Abstract

Waste management is a pressing issue in Probolinggo Regency and City, necessitating swift action to mitigate environmental impacts. The construction of the Probolinggo Regional Waste Landfill (TPA) aims to address this challenge through cross-regional sanitation services. Proper financing is crucial for successful infrastructure development, and this study compares government budget (APBN/APBD) and non-government (regional loans) financing schemes. Utilizing a quantitative approach with primary and secondary data, the analysis indicates the viability of both financing options. Government-sourced investment shows an NPV of Rp 431,148,007,790, IRR 40.55%, BCR 1.07, and a 3-year payback period. Meanwhile, non-government or regional loans exhibit an NPV of Rp 110,115,495,905, IRR 9.03%, BCR 1.3, and a 9-year payback period. The decision-making process, weighing financial and non-financial criteria, favors regional loans/loans as the preferred financing scheme for the Probolinggo TPASR project. This research emphasizes the importance of a well-selected financing scheme to ensure the success and sustainability of the Probolinggo Regional Waste Landfill infrastructure.

Abstract

The problem in implementing the construction of the Madrasah Muallimin Muallimat Tambak Beras Jombang Building is that the available funds and time are limited. The approach regarding the material needed for this building work is light brick compared to other work items. In wall masonry work using light brick/hebel, it is necessary to analyze whether the work time can be faster and whether the price comparison obtained is cheaper. The research method used is Value Engineering analysis to produce cost savings. The results of this research include: a) Based on the results of cost and time analysis for wall items, namely by proposing alternative materials as replacements for the initial materials, resulting in cost savings of Rp. 28,298,995.61, and b) When compared with productivity, a builder is able to complete a red brick wall in 133 days, whereas with light brick wall material a builder is able to complete the work in 66 days. So, in terms of work speed, lightweight bricks are faster than red brick walls.

Abstract

In construction project control, the main factors of concern are quality, time and cost control. So it is necessary to use one method in the implementation of its control. This study aims to analyze the time and cost of the Raci OPD Office Building Construction project. The benefit of this research is to anticipate potential delays that occur in the project. The problem limitation is focused on work that has not been completed in the remaining time of the contract period. To analyze time and cost, this research uses Critical Path Method (CPM) and Time-Cost Trade- Off (TCTO) which begins with determining the work network and critical path. TCTO analysis is carried out by shortening the duration of work by adding 3 hours of overtime and calculating the Crash Slope of each job on the critical path. Rescheduling is done by accelerating the work that has the lowest cost The results showed that the most effective rescheduling was carried out on the Lt.3 Installation and Plastering work with the acquisition of an acceleration duration of 8 days. And the total cost required for this acceleration is Rp. 29,441,424, - or Rp. 1,226,726,- per day for 24 days.

Abstract

The use of personnel applications for data collection and archiving employee information is crucial for every agency, including the Civil Service Police Unit and Tapin Fire Department. Despite having existing means for personnel data collection and archiving, the agency lacks a proficient personnel application. Currently, data collection and archiving are still carried out manually using Microsoft Word and Excel. Additionally, some data is stored in hard copy form and placed in binders, making it susceptible to damage or loss. Recognizing these challenges, the idea of developing a website-based personnel application emerged to streamline the personnel department's processes. The chosen programming languages for this application are PHP, HTML, and the Laravel Framework, with MySQL as the database. The research employed the waterfall model, incorporating data collection techniques such as observation, interviews, and documentation. The research findings reveal that the Tapin Civil Service Police Unit and Tapin Fire Department lack a competent human resources application. Consequently, a comprehensive application has been developed to address these shortcomings. Test results demonstrate that the application's features function as intended. In essence, the creation of this application has successfully met its primary objective of addressing data collection and archiving issues within the Civil Service Police Unit and Tapin Fire Department.

Abstract

Contractors involved in construction projects face the crucial challenge of effectively managing time to ensure the timely completion of the project as stipulated in the contract, if not earlier. Efficient time management not only facilitates adherence to contractual obligations but also transforms incurred costs into profitable outcomes, thereby preventing financial penalties associated with project delays. Consequently, the strategic implementation of acceleration efforts emerges as a pivotal solution to address and mitigate the complexities inherent in construction project timelines. The acceleration process is intricately tied to the identification and prioritization of critical activities within the project schedule. By employing a comprehensive approach that integrates both cost and time analyses, the Crashing method with additional modifications emerges as a valuable tool in this endeavor. The Crashing method involves a strategic acceleration of critical activities, coupled with a meticulous calculation of the additional costs incurred due to the acceleration process. A compelling case study that exemplifies the efficacy of the Crashing method and its supplementary measure of alternative overtime work is evident in the Tanjung Uncang Pier construction project in Batam City. Through the meticulous application of the Crashing method and the incorporation of alternative overtime work, the project's completion timeline was successfully curtailed from the originally delayed schedule of 257 calendar days to a more expedited 244 calendar days.

Abstract

Watu Ulo Beach serves as a vital hub for fishing communities, supplying resources for sea fishing and serving as a landing point for catches. The local government plans to construct a fishing port at Watu Ulo to enhance facilities for fishermen. This study assesses the financial feasibility and sensitivity of investing in the port's construction, considering three income scenarios: pessimistic, moderate, and optimistic. Financial analysis using NPV, IRR, BCR, and PP methods deems the project feasible for moderate and optimistic scenarios, but not for the pessimistic scenario due to IRR (6.15%) < MARR (7.72%). Sensitivity analysis reveals that revenue sensitivity is critical for all scenarios, with the investment becoming unfeasible if revenue falls below certain thresholds: -13.67% for pessimistic, -39.96% for moderate, and -40.75% for optimistic scenarios. Operating cost sensitivity is also crucial, rendering the investment unfeasible if costs deviate beyond specific thresholds: -15.96% for pessimistic, +22.67% for moderate, and 25.59% for optimistic scenarios.

Abstract

Project delays often serve as a catalyst for conflicts and disagreements between project owners and contractors, leading to significant financial implications. Such delays result in costly consequences for both parties involved. Contractors face the imposition of penalty fines as stipulated in the contractual agreement, alongside incurring overhead costs during the prolonged project duration. Conversely, owners experience a direct impact on their revenue streams due to delays in the operationalization of the facility. In the context of the construction of the Surabaya Open University Distance Learning Program Unit building phase II, the examination of cost and time performance becomes imperative. Employing the earned value method offers a comprehensive approach to project performance evaluation, involving a meticulous comparison of actual expenses and timelines with the initially anticipated costs. This analytical approach aids in understanding the project's progress and identifying areas where adjustments may be necessary to mitigate potential delays. The Earned Value Method (EVM) analysis of the Surabaya Open University Distance Learning Program Unit building phase II reveals a projected total cost of IDR 73,908,443,223.09 by the time the project reaches completion. This estimation provides stakeholders with valuable insights into the financial commitment required for the successful conclusion of the project. Additionally, the anticipated timeline for completion is estimated at 53 weeks, serving as a crucial parameter for project planning and management.

Abstract

The Kali Kamoning Watershed in Sampang Regency, spanning 35,421.15 Ha, experiences annual major floods affecting Sampang City. Despite various attempts and budget allocations at different administrative levels, flooding remains a persistent issue. A proposed solution is the implementation of an Ecodrains-based sponge village model for flood control, specifically targeting upstream areas like Karang Penang, Robatal, Kedungdung, Omben, and Sampang sub-districts. The model, cost-effective and easy to construct, utilizes the HEC-HMS software for technical analysis, simulating river capacity and calculating flood reduction. The sponge village model demonstrates a substantial reduction of flooding by 73.14%, equivalent to 326.3 m3/sec. The Q25th flood discharge measures 446.1 m3/sec. Estimated construction costs using the SNI method amount to IDR 917,588,260,000, aiming to control the Q25th flood. This innovative approach offers a promising strategy for mitigating flooding in Sampang City through sustainable watershed management and cost-efficient infrastructure development. Key terms: Watershed, Flood Reduction, Ecodrains, Sponge Village Model, HEC-HMS, Q25th, Construction Costs.
