Sandra Amalia, Yuliani Setyaningsih, Suroto Suroto — Wed, 23 Jul 2025 00:00:00 +0000

Carpal tunnel syndrome (CTS) is a prevalent musculoskeletal disorder resulting from compression of the median nerve in the wrist, leading to symptoms such as pain, tingling, and weakness in the hands. Workers in the informal sector, particularly tailors, are at significant risk due to repetitive hand movements, prolonged static postures, and suboptimal ergonomic conditions. This study aims to analyze the occupational risk factors associated with CTS complaints among informal sector tailors in Cimahi City, focusing on age, smoking habits, and working hours. Using a cross-sectional design, data were collected from 107 tailor respondents through purposive sampling and assessed via structured questionnaires. The findings revealed a statistically significant association between age and CTS complaints (p-value = 0.001), indicating that older workers are more susceptible to the disorder. However, no significant correlation was found between smoking habits and CTS complaints (p-value = 0.269). Conversely, a strong association was identified between working hours and CTS complaints (p-value = 0.001), suggesting that prolonged working time increases the risk of developing symptoms. This research contributes valuable insights into occupational health risk factors for tailors, emphasizing the need for improved workplace ergonomics and targeted preventive interventions.

Wed, 16 Jul 2025 00:00:00 +0000

Suradadi District is one of the districts in Tegal Regency, located in the Pantura (North Coast) area of Java. The availability of clean water is a significant issue in coastal regions, as wells that have been dug often yield brackish to saline water. The objective of this study is to identify the distribution of seawater intrusion in the coastal area of Suradadi District, Tegal Regency. The method employed is the Vertical Electrical Sounding (VES) geoelectrical method at five measurement points, each spaced approximately 600 meters apart. Data acquisition was carried out at five parallel lines, with point spacing ranging from 300 to 1000 meters. Seawater intrusion in the study area is widespread, extending up to approximately ±2300 meters inland from the coastline. Intrusion was identified at depth intervals as follows: point 1 at depths of 0.5–27 meters, point 2 at 1–27 meters, point 3 at 3.5–13 meters, point 4 at 10–14 meters, and point 5 at 14–17 meters. The extent of intrusion in this area is primarily attributed to the lithological composition, which is dominated by alluvial deposits consisting of sand, silt, and clay.

Annisa Triana Talmera, Mahendra Wardhana, Vita Ratnasari — Tue, 15 Jul 2025 00:00:00 +0000

The increasingly intense competition in Indonesia's e-commerce industry is compelling platforms like Tokopedia to shift from price war strategies to enhancing user experience to build long-term loyalty. This study aims to analyze the influence of User Interface (UI) and User Experience (UX) elements on User Satisfaction and User Loyalty on the Tokopedia platform. Specifically, this research also examines the mediating role of User Satisfaction in the relationship between UI/UX and User Loyalty. This research utilizes a quantitative approach with non-probability sampling through a purposive sampling technique. Data were collected via an online questionnaire distributed to 150 active Tokopedia users residing in the Jabodetabek area. The data analysis technique used is Partial Least Squares Structural Equation Modeling (PLS-SEM) with the SmartPLS 4 software. The results indicate that User Interface (UI) and User Experience (UX) have a positive and significant effect on User Satisfaction. Subsequently, User Satisfaction is also proven to have a positive and significant effect on User Loyalty. However, the key finding of this research is the insignificance of the direct effects of UI and UX on User Loyalty. Further analysis confirms the role of User Satisfaction as a full mediation variable. This indicates that the entire influence of UI and UX on User Loyalty is fully channeled through User Satisfaction. This study concludes that satisfaction is a crucial strategic bridge that must be crossed to convert a good user experience into tangible customer loyalty. The implication for Tokopedia is that investments in UI/UX improvements will not be effective in increasing loyalty if they are not accompanied by strategies that ensure these features genuinely satisfy users first.

Shorea Helminasari, Shakira Mustafa, Muhammad Edhil Arfan — Sat, 26 Jul 2025 00:00:00 +0000

Waste has become a serious global issue experienced by almost all regions of the world, including Indonesia. The prevailing stigma in waste management within society has been that the government handles waste from the source, to temporary disposal sites (TPS), and then to final disposal sites (TPA). Waste management is a major challenge often faced by urban communities, including the city of Samarinda. Samarinda has various destination areas with tourism and economic potential that attract the attention of local residents as well as international visitors. One such place is Kampung Ketupat, a tourism village located in Samarinda Seberang District, Mesjid Subdistrict, specifically in the Mangkupalas Road area. This area is officially managed by the Tourism Awareness Group (Pokdarwis), which reports that some residents still frequently dispose of waste into the river without proper waste disposal management. Kampung Ketupat has great potential to become a sustainable community-based ecotourism area. Strategic steps in distributing information related to independent waste management by involving creative industry players and local communities will not only help reduce environmental impacts but also increase public awareness of the importance of environmental sustainability as a tourism asset. Kampung Ketupat can serve as a model for community-based waste management in line with Samarinda City Regional Regulation Number 5 of 2021 concerning waste management. This activity aims to implement a community-based service model in Kampung Ketupat, Samarinda City, involving Pokdarwis as well as the local government. The activities include training, seminars, public discussions, and community awareness campaigns. Regular evaluations will be conducted to ensure the sustainability and success of this program. It is expected that the residents of Kampung Ketupat, Samarinda City, will be more actively involved in independent waste management and the creative industry as a potential ecotourism industry.

Factors Affecting the Underpricing of Shares of Companies that Conduct Initial Public Offerings with the Auditor's Reputation as a Moderator

Tue, 15 Jul 2025 00:00:00 +0000

Underpricing remains a prevalent phenomenon in initial public offerings (IPOs) in Indonesia. Despite global and national economic uncertainties, statistical data from the Indonesia Stock Exchange (IDX) reveal significant growth in both the investor base and the number of IPOs during the 2020–2024 period. This study aims to identify the determinants of underpricing for companies that conducted IPOs on the IDX between 2020 and 2024, with auditor reputation serving as a moderating variable. This quantitative research employs Signaling Theory to analyze the informational cues available during and after the IPO process. The independent variables examined in relation to underpricing include Return on Assets (ROA), Debt to Equity Ratio (DER), Earnings Per Share (EPS), and Firm Size, with Auditor Reputation incorporated as a moderating variable to assess its influence on the relationships. The study’s population consists of firms that completed IPOs on the IDX from 2020 to 2024. A purposive sampling technique was utilized, resulting in a final sample of 177 companies. Data analysis was conducted using SPSS software, specifically applying the Moderated Regression Analysis method. The findings offer empirical evidence that DER has a significant effect on underpricing. In contrast, ROA, EPS, and Firm Size do not exhibit a statistically significant impact on underpricing. Furthermore, statistical tests indicate that Auditor Reputation does not enhance the moderating effect of ROA, DER, EPS, or Firm Size on underpricing.

Effect of the Addition of Sikacrete-W and Viscocrete-3115n on the Compressive Strength of Concrete in Waterlogged Bore Pile Casting Work

Wed, 23 Jul 2025 00:00:00 +0000

This study examines the effect of the addition of Sikacrete-W and Viscocrete-3115N additives on the compressive strength of concrete in waterlogged bore pile casting work. Concrete is an important construction material, but underground casting can lead to washout and segregation, which negatively impacts concrete quality. In this study, variations of Sikacrete-W addition of 3%, 5%, and 10% and 0.6% Viscocrete-3115N were used to improve the cohesion and viscosity of the mixture. The test results showed that the average compressive strength of concrete with the addition of additives was lower than that of normal concrete, with the largest decrease occurring in the 10% Sikacrete-W mixture. Meanwhile, a 5% Sikacrete-W mixture yielded an optimal compressive strength of 31.74 MPa, suggesting that the addition of additives could affect the characteristics of concrete under special conditions.

Lupus Erytematous Syndrome and Anti Phospolipid Syndrome in a 44-Year-Old Man

Aqsha Tiara Viazelda, I Nyoman Suarjana — Mon, 28 Jul 2025 00:00:00 +0000

Antiphospholipid syndrome (APS) is a blood clotting condition characterized by thrombosis and obstetric disorders, more common in women. This case is rarely found in men due to vague symptoms. We reported a 34-year-old male patient who was admitted to Ulin Hospital on April 6, 2022 with complaints of headache, joint pain, and a history of autoimmune disorders. The patient develops cerebrovascular conditions at a young age. The diagnosis is made based on an anamnesis, physical examination, laboratory, and CT Scan, which shows Systemic Lupus Erytematous with APS. Laboratory results showed increased leukocytes, cholesterol, and coagulation, as well as high anticoagulant lupus. The therapies provided include methyl prednisolone, hyloquin, Myfortic, and the anticoagulant warfarin with a target of INR 2-3. The manifestations of APS and Lupus Erytematous vary, so a proper clinical approach is required. The diagnosis of APS in men is often overlooked due to the lack of obvious obstetric symptoms. Without supporting examinations, treatment cannot be carried out effectively, which can worsen the patient's condition. Patients are required to routinely monitor INR for anticoagulants, and evaluations are required for laboratory examinations to prevent economic losses.

Amiodarone, Extreme AV Block and Pseudo-Pacemaker Syndrome: A Malady Caused By A Cure

Tue, 22 Jul 2025 00:00:00 +0000

Amiodarone is a potent antiarrhythmic that is used to treat supraventricular tachycardia (SVT). However, its substantial impact on atrioventricular (AV) nodal conduction can obscure or exacerbate underlying delays, resulting in rare conditions such as pseudo-pacemaker syndrome (PPMS). This syndrome is the result of an extreme prolongation of the PR interval, which results in AV dyssynchrony and hemodynamic compromise in the absence of an implanted device. A 25-year-old male presented with SVT, which was further complicated by hypokalemia. The case revealed a pre-existing AV nodal conduction delay. Therefore, we present the case. The patient transitioned to sinus rhythm after receiving amiodarone; however, they experienced a persistent and severe PR interval prolongation that exceeded 400 ms. The symptoms of vertigo and palpitations, which were consistent with PPMS, were induced by this severe conduction block and persisted for more than ten days, a reflection of the long half-life of amiodarone. This case concludes that amiodarone can dangerously exacerbate latent AV nodal disease in young adults, underscoring the necessity of recognizing PPMS as a clinical consequence of iatrogenic PR prolongation and emphasizing the need for cautious use and monitoring of antiarrhythmic drugs in patients with any evidence of conduction abnormalities.

Gilbert Stefhen, Dedy Suryadi, Titi Iswari — Sat, 19 Jul 2025 00:00:00 +0000

The rapid growth of the e-commerce sector in Indonesia has increased the demand for reliable and timely logistics services. However, challenges such as delayed pickups and deliveries continue to occur, leading to the accumulation of operational penalties. This study aims to develop a mathematical model based on the Vehicle Routing Problem (VRP) that addresses the complexities of modern logistics distribution. The proposed model, named HFMTVRPDPTW (Heterogeneous Fleet Multi-Trip Vehicle Routing Problem with Delivery and Pickup and Time Windows), incorporates five key elements: vehicle capacity, fleet heterogeneity, service time windows, simultaneous pickup and delivery, and multi-trip operations within a single working period. A systematic literature review of twenty-one prior studies was conducted to identify research gaps and inform the model’s development. The model is formulated using an integer linear programming (ILP) approach and aims to optimize service time accuracy while minimizing delays. The findings suggest that this model provides a more comprehensive and realistic approach to distribution challenges and offers an original contribution to the development of adaptive and efficient VRP models for logistics operations.

Hypertension is a leading non-communicable disease-causing mortality and reducing employee productivity. Its high prevalence in the workplace is linked to lifestyle factors and low awareness of prevention. This study aimed to analyze the effect of hypertension prevention programs on employee awareness and hypertension status in animal feed companies in Semarang. A quasi-experimental design with pre-test and post-test control groups was employed. From a population of 257 employees, 30 samples were selected for each group. Data were collected via questionnaires and observation sheets. The intervention consisted of a hypertension prevention program including

sosialisasi

(socialization) about hypertension prevention and routine blood pressure monitoring. Data analysis used paired t-tests and Wilcoxon tests. Sixty subjects participated, with mean ages of 43.87 years (intervention) and 40.23 years (control). In the intervention group, 60% had a family history of hypertension. Significant improvement in awareness was observed in the intervention group (p = 0.000) but not in the control group (p = 0.493). The intervention significantly reduced systolic (p = 0.000) and diastolic (p = 0.012) blood pressure and lowered hypertension prevalence from 63.3% to 40%, whereas the control group showed no change. In conclusion, workplace hypertension prevention programs effectively increase employee awareness and reduce blood pressure and hypertension prevalence. These programs are recommended as preventive strategies in occupational health management.

Slamet Wahyudi, Vita Ratnasari — Thu, 31 Jul 2025 00:00:00 +0000

Harmonious relations between companies and surrounding communities are the dream of every industry. In reality, however, industries often experience conflicts with surrounding communities. This is due to several factors, namely those related to employment and environmental impacts. A notable social conflict occurred in 2012 when approximately 64 local residents staged a demonstration. To mitigate such conflicts, the company has adopted a community engagement approach through its Corporate Social Responsibility (CSR) program. This study examines the alignment and implementation of CSR programs in relation to their impact on environmental performance at a bio-manufacturing company located in East Java, Indonesia. To date, the company's CSR programs have incorporated suggestions from the local community. Based on company data, the percentage of social CSR programs is highly dominant at 83.5%, consisting of charity, religious, and natural disaster relief initiatives. This study employs an explanatory quantitative approach to test existing theories or hypotheses, aiming to strengthen or add to previous research findings. While other studies only use the CSR disclosure variable, this study includes the type of CSR variable that influences CSR disclosure and several external influences on environmental performance. The sample size for this study is 300 respondents from the community surrounding the company. Data was collected through the distribution of questionnaires and analyzed using SEM-PLS software. The results of the study indicate that CSR disclosure, pro-environmental community actions, and environmental NGOs have a positive and significant effect on environmental performance. The suitability of CSR programs for the community is the main factor influencing the value of CSR disclosure satisfaction. This study shows that the appropriate CSR programs for companies are social CSR, health CSR, and environmental CSR.

Lissa Pratiwi, Endang Parahyanti — Tue, 15 Jul 2025 00:00:00 +0000

Based on data from the Ministry of Education and Culture in 2024, there is a difference in the implementation and learning outcomes of the Independent Curriculum between the secondary school level and the elementary school level. School readiness, one of which is the capacity of teachers, is a factor in this difference. From previous research, an individual's capacity to be ready to change affects an organization's readiness to face change. This study aims to see the influence of Psychological Capital on Readiness for Change with the Perception of the Effectiveness of the Professional Learning Community as a moderator. Participants are 143 high school teachers (SMP/SMA/SMK/equivalent) who have been active in the Professional Learning Community in the past year, either MGMP or Learning Community. Sampling with non-probability sampling, specifically convenience sampling. The measurement tools used are the Readiness for Change Scale (Hanpachern, 1997), the Psychological Capital Questionnaire (PCQ-12) (Luthans et al., 2007), and the Professional Learning Community Assessment-Revised (PLCA-R) shorter version (Moosa et al., 2020). The results of the regression test with Hayess' macro-PROCESS Model 1 show that Psychological Capital has a positive and significant influence on Readiness for Chang. However, the Professional Learning Community cannot moderate the influence of Psychological Capital on Readiness for Change. Interventions on Psychological Capital, for example in the form of training, can be carried out by both school management and policy makers in education to increase teachers' readiness to change, especially in this era of highly dynamic educational change.

Naila Zanubah Arifah, Dina Helianti, Erfan Efendi — Mon, 28 Jul 2025 00:00:00 +0000

The aging process leads to skin changes such as wrinkles and loss of elasticity, often accelerated by premature aging caused by factors like UV radiation and reactive oxygen species (ROS). Elastase, an enzyme responsible for degrading elastin in the skin’s extracellular matrix, plays a critical role in this process. This study aimed to investigate the anti-elastase potential of koro komak (Lablab purpureus) extract, a plant rich in polyphenolic compounds, through in vitro testing. A quasi-experimental design was employed, using different concentrations of the extract compared to ascorbic acid as a positive control. Phytochemical screening confirmed the presence of flavonoids, phenols, and tannins. The extract exhibited moderate anti-elastase activity with an IC?? value of 128 ?g/mL, and at 200 ?g/mL concentration, it inhibited elastase enzyme activity by 65.90%. These findings suggest that koro komak extract has promising potential as a natural anti-aging agent by protecting skin elasticity through elastase inhibition.

Marriage or Freedom? Indonesia's Generation-Z Dilemma in the Midst of Social and Economic Pressure

Tue, 15 Jul 2025 00:00:00 +0000

This study aims to explore Indonesian Generation Z's perceptions of the institution of marriage, identify factors driving marriage postponement, and understand the dynamics of social value change in contemporary society. Using a phenomenological qualitative approach, this research involved 15 participants aged 18-28 from South Jakarta, Bogor, and South Tangerang who were interviewed in-depth with semi-structured guidelines. Data analysis was conducted using NVivo software through open coding, axial coding, and selective coding stages. The results show that Generation Z still regards marriage as a sacred and meaningful institution, but positions it more personally and reflectively as a legal and emotional commitment undertaken consciously. The decision to postpone marriage is influenced by factors of financial readiness, mental and emotional maturity, and alignment of life vision and mission with partners. Meanwhile, social values about marriage have undergone significant shifts from primary life goals to flexible, egalitarian life choices based on self-actualization. Digitization and social media exposure are also found to be factors that strengthen anxiety toward long-term relationships, especially through negative narratives about divorce or unhealthy relationships. These findings align with Maslow's theory of needs, where Generation Z's decisions about marriage reflect the need for financial security, self-esteem, and self-actualization. This study makes an important contribution to enriching qualitative literature on Indonesian youth relationship dynamics, while offering recommendations for BKKBN, Ministry of Youth and Sports, and educational institutions in formulating youth empowerment policies and relationship literacy education.

Route Choice Analysis to Office Areas Using “All or Nothing” Approach and User Perceptions

Wed, 23 Jul 2025 00:00:00 +0000

Route selection is a critical process in designing an efficient transportation system, as inaccuracies in route choice can lead to delays and adverse effects on worker health and productivity. The purpose of this study is to identify preferences and factors influencing the selection of travel routes, as well as to map alternative routes based on these influential factors. The methods employed in this study include a questionnaire survey of office workers, which was then analyzed using the ordinal logit model and multinomial logistic regression with the assistance of SPSS software. Additionally, the all-or-nothing assignment method was applied to determine the optimal routes, using ArcGIS as a geospatial mapping and analysis tool. The results indicated that traffic density, distance, travel cost, and travel time were the primary factors affecting route choice decisions, with cost being the most significant. Conversely, individual characteristics such as age, gender, and education level did not have a statistically significant effect. This study recommends the adoption of an alternative route selection model to identify the most efficient commuting routes from various zones within the region, considering key factors such as traffic congestion levels, distance, cost, and travel time efficiency.

Dwi Suwondo, Evi Octavia — Tue, 15 Jul 2025 00:00:00 +0000

This study aims to analyze the cost of hemodialysis services in patients with Chronic Kidney Failure (CKD) at Dr. Abdul Radjak Purwakarta Hospital using the Activity-Based Costing (ABC) approach with a bottom-up method. In addition, this study also identifies inefficiency factors through Value Stream Mapping (VSM) analysis. This study is quantitative descriptive research that aims to determine the value of independent variables, either one or more variables, without making comparisons with other variables. The results of the study showed that the cost of hemodialysis units amounted to Rp 949,048 per action, consisting of direct costs of Rp 752,513, direct resources overhead of Rp 131,498, and indirect resources overhead of Rp 65,037. The largest cost component comes from the labour-related aspect, accounting for 62.7% of the total direct costs, followed by service-related (24.2%) and non-functional unit employee costs (75.72% of indirect overhead). The efficiency of the service process reached 92%, but it was found that 8% of non-value added activities mainly occurred in the registration and final administration process. A comparison between ABC's unit cost and INA-CBG's rate shows a cost difference, with a cost recovery rate of 99%, which means hospitals have a deficit of 1% per procedure. The results of this study confirm the importance of using the ABC method in the calculation of hospital service costs as well as the integration of lean approaches to improve operational efficiency and accuracy of financial decision-making in the hemodialysis service unit.

The Wakal-Taeno road on Ambon Island is a crucial link between Ambon City and the Leihitu sub-district. Although completed in 2023 using Presidential Instruction funds and officially operational in 2024, the road has already experienced multiple functional failures. This study retrospectively analyzes contributing factors and reassesses risks using the SNI ISO/IEC 31010:2016 standard. Primary data were collected through visual field inspections, supported by secondary data from news reports and academic sources. Root Cause Analysis (RCA) was employed to identify core problems, while the ISO framework guided risk identification, probability-impact analysis, and risk evaluation. Key issues identified include the collapse of a temporary Bailey bridge in June 2025, landslides on slopes, and settlement of bridge approaches. RCA revealed root causes such as insufficient geotechnical and hydrological investigations, unsuitable design and materials selection, incomplete risk assessments, and reactive, rather than proactive, maintenance strategies. The risk reassessment categorized bridge collapse, slope failures, and approach instability as high and unacceptable risks (risk scores: 16–20), while drainage system deficiencies were moderate (score: 12), and early pavement degradation was low (score: 9). Recommendations include constructing permanent bridges designed according to local geotechnical conditions, slope stabilization and reinforcement, integrated drainage systems, and proactive maintenance programs. Applying the SNI ISO/IEC 31010:2016 framework from the planning stage, alongside enhanced inter-agency coordination, is essential for sustainable infrastructure development in hazard-prone regions. Validation was ensured through data triangulation, member checking, and methodological transparency to strengthen the study’s credibility.

The Use of Type D and Type F Admixtures Concrete and Their Effects on Setting Time and Compressive Strength

Tue, 15 Jul 2025 00:00:00 +0000

The challenges of concrete usage in Indonesia, such as hot weather, remote construction sites, and improper manual casting practices, often lead to reduced concrete quality due to excessive water addition. This study investigates the effects of Type D (*Sika-Plastiment-83am*) and Type F (Sikament-LN) admixtures on concrete's setting time and compressive strength to address these issues. The research aims to optimize admixture dosages (0.2%, 0.25%, and 0.3% by cement weight) to enhance concrete performance while adhering to SNI and ASTM standards. Methods included literature reviews, field studies, and laboratory tests, such as slump tests, compressive strength tests (at 7, 14, and 28 days), and initial setting time measurements using penetrometers. Findings revealed that admixtures significantly improved compressive strength (31.6–34.0 MPa, exceeding the 30.0 MPa target) and extended initial setting times (3 hours 45 minutes to 5 hours 10 minutes) compared to untreated concrete (2 hours 20 minutes). The optimal dosage balanced workability (slump: 12±2 cm) and delayed hardening, ensuring suitability for casting. The study concludes that admixtures effectively replace water addition, enhancing strength and workability while mitigating premature drying. Practical implications include recommendations for admixture use in hot climates and remote projects to maintain concrete quality and durability.

It reflects a contextual form of mindfulness—spiritually rooted and harmoniously integrated with nilai budaya (cultural values) and keseimbangan batin (inner balance). Thus, this study affirms that mindfulness, when grounded in local traditions, can serve as a genuine form of indigenous psychology rooted in collective identity and cultural wisdom.

Utilization Of Waste Glass Material In Asphalt Concrete-Wearing Course (Acwc) As A Substitute For Fine Aggregate

Sat, 19 Jul 2025 00:00:00 +0000

Sustainable development encourages the use of waste as an alternative material in infrastructure, including on road pavement. This study evaluated the performance of Laston Coated Wear (AC-WC) asphalt mixture with the substitution of glass waste as fine aggregates in variations in 0%, 10%, 20%, and 30% levels. Material characteristics testing as well as Marshall tests and residual stability were carried out referring to the General Specification of Highways Division 6 of 2018 Revision 2. The results show that the glass waste meets the technical specifications as a fine aggregate. Blends with 10% glass content produce the highest Marshall stability value of 93.4% and the best overall performance. The Optimum Asphalt (KAO) content has increased as the glass content has increased, but it remains below the normal mix KAO. Mixing with glass also shows good water resistance. Therefore, a 10% glass waste substitution is recommended as an alternative to fine aggregates in AC-WC mixtures to support environmentally friendly road infrastructure.
