Abstract

This research intends to evaluate the features of traffic flow and the effectiveness of road infrastructure along Jl. A Yani Gedangan in Sidoarjo Regency. The study was carried out on a 1. 2-kilometer stretch from KM 2+100 to KM 3+300 over a week (from March 10 to March 16, 2026). Methods for field surveys involved measuring traffic volume, speed, travel duration, and road layout. The analysis of road performance is based on the 2023 Indonesian Road Capacity Guidelines (PKJI). Findings indicate that the Average Daily Traffic (ADT) stands at 17,867 passenger car units per day, with motorcycles constituting 65 percent of that total. The highest traffic volumes are recorded from 07:00 to 08:00, reaching 2,150 pcu per hour, and from 16:00 to 17:00 with 2,080 pcu per hour. The road's capacity is determined to be 2,344 pcu per hour, and the degree of saturation is calculated at 0. 917 during the morning peak and 0. 887 in the afternoon peak, categorizing it as saturated. In the morning peak hours, the average speed decreases to 18 kilometers per hour, resulting in a Level of Service rating of F, indicating severe congestion. In summary, the traffic flow characteristics on Jl. A Yani Gedangan are primarily dominated by motorcycles, featuring distinct morning and evening peak periods. However, the performance of road infrastructure falls short of acceptable standards due to high saturation levels, lower-than-acceptable speeds, and inadequate levels of service. Recommendations include measures to lower traffic volumes during peak times, implement controls on illegal parking, and enhance road infrastructure

Abstract

The Damri transport service operating between Terminal Purabaya and Juanda Airport is currently facing a situation of low usage of its fleet capacity. This scenario is reflected in the load factor, which stays under the ideal benchmark of 70% for public transportation, according to the Decree issued by the Director General of Land Transportation Number 687 of 2002. Such a situation highlights the necessity for enhancements in service quality and accompanying facilities. The purpose of this study is to pinpoint the existing gaps in service, establish priorities for service enhancement based on the significance and effectiveness of service characteristics, and evaluate the viability of creating waiting room facilities to aid in elevating service quality. The findings indicated that the most significant gap was identified in the disabled passengers' amenities, with a figure of (-1.74). Utilizing Importance Performance Analysis (IPA), four key factors were identified as top priorities for enhancement: information regarding security disturbances, service-related information, waiting area amenities, and accommodations for passengers with disabilities. The analysis of the viability related to the costs of constructing the Damri bus waiting area demonstrates that the endeavor is viable to proceed, exhibiting an IRR of 46%, a BCR greater than 1, and a positive NPV across all evaluated interest rates

Abstract

This study aimed to examine the effects of self-efficacy, technology support, learning motivation, learning environment, and digital literacy on the pedagogical readiness of students in the Primary Teacher Education Program (PGMI) at IAIN Curup. A quantitative survey design was employed, involving 408 students selected through stratified random sampling. Data were collected using a structured questionnaire and analyzed through Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results indicated that all constructs met the required validity and reliability criteria. Hypothesis testing revealed that self-efficacy, technology support, learning motivation, learning environment, and digital literacy each had a positive and significant effect on students’ pedagogical readiness. Among these factors, learning motivation emerged as the strongest predictor, followed by learning environment, self-efficacy, technology support, and digital literacy. The findings further demonstrated that the proposed model possessed substantial explanatory power, with an R² value of 0.787, indicating that 78.7% of the variance in pedagogical readiness was explained by the five predictor variables, while the remaining variance was attributable to factors outside the model. The study concludes that pedagogical readiness is shaped by the interaction of psychological, environmental, and technological factors. These findings provide important implications for developing more comprehensive and adaptive teacher education programs to meet the demands of twenty-first-century education

Abstract

Pain is one of the most common problems experienced by post sectio caesarea patients due to tissue damage. Poorly managed pain can interfere with the recovery process and patient comfort. Finger hold relaxation therapy is a non-pharmacological method that can help reduce pain by providing physical and emotional relaxation effects. The purpose of this study was to determine the effect of finger hold relaxation therapy on pain scale in post sectio caesarea patients at H.A Zaky Djunaid Hospital, Pekalongan City. This study used a quantitative research method with a quasi-experimental design using a pre-test post-test with control design. The sample consisted of 40 respondents, divided into 20 intervention and 20 control groups, using total sampling technique. The instrument used was the Numeric Rating Scale (NRS) to measure pain levels and SOP for finger hold relaxation therapy. Data analysis was conducted to determine differences before and after intervention. The results showed a decrease in pain scale in the intervention group compared to the control group. Statistical analysis indicated that finger hold relaxation therapy had a significant effect on reducing pain scale in post sectio caesarea patients. Finger hold relaxation therapy is effective in reducing pain scale in post sectio caesarea patients

Abstract

Sheath rot disease, triggered by Rhizoctonia solani infection, is a major pathological constraint in corn cultivation. Clinical manifestations of this disease are generally indicated by the appearance of necrotic spots on the leaf collar (auricle) and leaf blade, accompanied by tissue decay in the sheath area. This fungal agent has flexible transmission capabilities through air and soil, and can even survive in the soil for more than two years by forming dormant structures called sclerotia. This experiment was conducted in the Laboratory of the Faculty of Agriculture, Pattimura University, from April 9 to April 20, 2025. The main focus of this study was to explore the potential of plant extract-based biopesticides as alternative control agents that are environmentally friendly and able to maintain the quality of agricultural commodities. Statistical analysis using ANOVA revealed significant variations in the effectiveness of the formulas in suppressing pathogen development. Through these findings, this research is expected to contribute scientifically to the development of more sustainable crop protection methods in corn cultivation management

Abstract

The conversion of agricultural land in Indonesia continues to increase due to industrial, housing, and infrastructure development that is not balanced with efforts to protect sustainable food land. This condition poses a threat to food security, environmental sustainability, and agrarian justice. This research aims to reconstruct agrarian policies in controlling sustainable agricultural land conversion in Indonesia through an analysis of the effectiveness of regulations, institutions, and the implementation of applicable policies. The research uses normative legal methods with legislative, conceptual, and socio-legal approaches. Data was obtained through literature studies, documentation, and interviews with 15 informants consisting of academics, local governments, and farmers. Data analysis was carried out qualitatively through legal interpretation techniques and thematic analysis. The results of the study show that the policy of controlling land use transfer is still sectoral, there is weak supervision, and there is an insynchronization between spatial planning policies and economic development. This research offers a reconstruction of agrarian policies based on integrated governance, strengthening supervision, and legal protection of sustainable agricultural land

Abstract

Planned Value (PV) represents the expected expenses for tasks designated for a particular timeframe and outlined in the financial plan, also referred to as the Budgeted Cost of Work Scheduled (BCWS). This figure is calculated by taking the proportion of intended progress as per the timeline and multiplying it by the expenses earmarked for the project as detailed in the Bill of Quantities (RAB). PV or BCWS = (percentage of planned progress) x (Budget) PV or BCWS calculation for Week 1. PV or BCWS = (percentage of plan) x (total budget for the project) PV or BCWS = (0. 07%) x (Rp. 2,270,000,000). PV or BCWS = Rp. 1,589,000. Earned Value (EV) or BCWP reflects the budgeted costs associated with work that has been finished, calculated by multiplying the percentage of actual progress by the budget. EV or BCWP = (percentage of actual progress) x (Budget) EV or BCWP calculation for Week 1. EV or BCWP = (percentage of actual progress) x (total budget for the project) EV or BCWP = (0. 07%) x (Rp. 2,270,000,000). EV or BCWP = Rp. 1,589,000. According to the assessment conducted, the project duration was completed 7 days ahead of the projected timeline of 133 days. The assessment indicated that the final expenses were below the contracted amount of Rp. 2,189,355,000, resulting in cost efficiency

Abstract

The implementation of the Responsive Phase through Critical Path Method (CPM) analysis has successfully identified the impact of flood force majeure on the project's critical path quantitatively. Based on the project's weekly report data, an additional duration of 14 days was determined for the Structural Excavation and 28 days for the Vero River due to inundation, which was officially documented in the supervisor's instruction letter to the PPK. The results of the impacted CPM analysis indicate a shift in the project completion date from November 17, 2025, to December 1, 2025, so that the EOT amount of 14 calendar days was determined as the contractor's contractual right based on Articles 1244–1245 of the Civil Code. This delay is categorized as an excusable non-culpable delay so that the contractor cannot be subject to delay fines (liquidated damages) for these 14 days. The Three Phase Intervention Model (Preventive–Responsive–Recovery) has been successfully formulated into an Applicable Work Guideline consisting of 21 systematic steps and equipped with a checklist of 12 formal legal attachment documents for EOT claims. This model integrates CPM analysis, EOT mechanisms, and crashing optimization in one continuous framework, Preventive produces a baseline schedule as a reference, Responsive identifies impacts and determines EOT rights, and Recovery formulates an optimal acceleration strategy. This guideline has been proven to strengthen the basis of contract administration and technical justification for claims for time extensions and acceleration costs on bridge projects affected by flood force majeure

Abstract

The construction of the New Classroom Building (RKB) at MIN 5 Tulungagung has potential Occupational Safety and Health (OSH) risks because it involves construction activities, work equipment, labor, and diverse project environmental conditions. This study aims to identify OSH risk factors, determine risk levels and priorities, and analyze the impact of dominant risks on project implementation time. The results show that there are 20 OSH risk factors classified into environmental, human, equipment, work method, and management/organizational factors. The highest dominant risk is the lack of internal communication and coordination among project parties, with a risk value of 12.240. Other priority risks include extreme weather 11.778, dust exposure due to construction activities 10.444, and lack of worker skills 10.427, which are classified as high risks, while not using personal protective equipment (PPE) 9.747 is classified as a moderate risk. No risks are classified as very high. Based on expert judgement, extreme weather has the greatest estimated delay of 1–7 days, while other risks may cause delays of 1–3 days. Therefore, OSH risk control needs to be implemented systematically to improve work safety, maintain work smoothness, and support timely project implementation
