Abstract

This research was conducted to assess the level of community satisfaction with clean water services provided through the PAMSIMAS (Community-Based Drinking Water and Sanitation Provision) program in Tihu Village, Bonepantai Subdistrict. Clean water is a fundamental necessity for life; however, the PAMSIMAS service still faces several issues, such as low water clarity and unstable supply, particularly during the rainy season. This evaluation aimed to identify the extent to which the community feels satisfied and to provide recommendations for program management improvement. This research employed a quantitative method with a descriptive design. The sample consisted of 60 respondents out of 150 active users, determined using the Slovin formula. Data were collected using a Likert-scale-based questionnaire covering seven main variables: water quality, continuity, reliability, accessibility, cost affordability, community participation, and responsiveness to complaints. The data were analyzed using SPSS with validity tests, reliability tests, and descriptive analysis. The results indicated that the majority of the community was reasonably satisfied with the PAMSIMAS clean water service, although complaints remained regarding water quality and availability. Then, validity and reliability tests confirmed that the research instruments were appropriate for use. The highest satisfaction levels were found in accessibility and affordability, while water quality and continuity received the lowest satisfaction scores. Overall, the PAMSIMAS clean water service in Tihu Village has provided considerable benefits; however, improvements are needed, particularly in technical aspects and water distribution management, to ensure sustainable and equitable service in the future.

Abstract

This research aimed to analyze the acceleration of project execution time using the Time Cost Trade Off (TCTO) method on the road preservation project of the Biluhu Barat – Gorontalo segment. Delays in construction projects may result in negative impacts on time, cost, and work quality. Therefore, acceleration strategies are required to reduce project duration without compromising cost efficiency. The TCTO method was applied through simulations involving overtime work and the addition of heavy equipment for activities located on the critical path. The data analyzed in this research included the time schedule, Budget Plan (RAB), and Unit Price Analysis (AHSP). Simulations were conducted on 7 critical path work items using Microsoft Project 2021 software. The analysis results indicate that applying the Time Cost Trade Off method with additional overtime hours led to both time and cost efficiency. The project cost under the 1-hour overtime alternative was recorded at IDR 42,011,519,325.19 with a duration of 146 days; for 2-hour overtime, the cost was IDR 42,190,670,502.55 with a duration of 142 days; for 3-hour overtime, the cost reached IDR 42,389,837,881.99 with a duration of 140 days; and for 4-hour overtime, the total cost was IDR 42,624,339,782.86 with a duration of 138 days.

Abstract

This study presents an in-depth analysis of the impact of the Time-Cost Trade-Off (TCTO) method on the time and cost efficiency of a project for the construction of septic tanks and their supporting facilities in Boalemo Regency. This construction project is part of the implementation of a Presidential Instruction (Inpres) aimed at improving domestic wastewater management in the region, with the project carried out in five subdistricts: Paguyaman, Paguyaman Pantai, Wonosari, Botumoito, and Mananggu. The research methodology utilized relevant secondary data, including the Budget Plan (RAB), the predetermined project duration schedule, and technical implementation records from the field. These data were comprehensively analyzed using Microsoft Project software and manual calculations to identify the critical path, as well as to calculate the crash duration, crash cost, and cost slope. Several acceleration scenarios were tested by adding 2, 3, and 4 hours of overtime. The results indicate that the addition of 2 hours of overtime achieved the most efficient balance, shortening the project duration to 72 days with a total cost of IDR 12,570,663,957. Meanwhile, the 3-hour overtime scenario reduced the duration to 70 days at a cost of IDR 12,639,692,694, and the 4-hour overtime scenario cut the duration to 69 days with a cost of IDR 12,708,721,431. These findings demonstrate that acceleration through overtime offers flexible options for project managers to achieve efficiency while considering the associated cost implications.

Abstract

Time and cost control are essential factors in ensuring the successful execution of construction projects. This study aims to compare project performance with the initial plan and evaluate the remaining time and cost required to complete the project. The Earned Value Analysis method was applied to analyze the project performance indices, allowing the assessment of cost efficiency, schedule efficiency, and the estimated time and cost required for project completion. The object of this study is the Food Security Warehouse Construction Project of the Indonesian National Police at Gorontalo Regional Police. The analysis was carried out using S-curve data, planned progress, and actual project cost realization. The analysis results show that from week 1 to week 17, the BCWP value is consistently higher than the BCWS value, indicating that the project progress is ahead of schedule (SPI > 1). This condition is reinforced by the ACWP value being lower than BCWP, as well as positive CV and SV values with CPI and SPI > 1, which demonstrates that cost and schedule control have been managed effectively and efficiently. Based on the estimation results, the project can be completed on time, cost-efficiently, and 100% without requiring additional budget, thus remaining within the initial budget limit of Rp5,180,854,000.

Abstract

Public transportation plays an important role in supporting community mobility and economic activities. One of the transportation modes that is still widely used by the public is the Intercity and Interprovincial Bus (AKAP). The success of bus transportation services is determined not only by the operator's ability to provide vehicles but also by the quality of services delivered to passengers. Passenger satisfaction is an important indicator in evaluating transportation service quality because it is closely related to customer loyalty and service sustainability. This study aims to analyze passenger satisfaction with the service quality of AKAP buses operating on the Gorontalo–Kotamobagu route at Dungingi Terminal and to identify service dimensions that require improvement. This research employed a quantitative approach using a survey method involving 65 respondents selected through purposive sampling. The research instrument was developed based on the five SERVQUAL dimensions, namely tangibles, reliability, responsiveness, assurance, and empathy. Data were analyzed using the Customer Satisfaction Index (CSI) and GAP analysis to measure the discrepancy between passengers’ perceptions and expectations. The results indicate that all research instruments were valid and reliable, with Cronbach’s Alpha values greater than 0.60. The GAP analysis revealed negative values across all service dimensions, indicating that the quality of service has not fully met passenger expectations. The tangibles and reliability dimensions showed the largest service gaps. Furthermore, the Customer Satisfaction Index value was 76.47%, which falls within the satisfied category. Nevertheless, improvements in service quality are still required, particularly regarding physical facilities, travel comfort, and departure punctuality.
