Abstract

The development of physical facilities in Indonesia is increasing rapidly along with the promotion of modernization. In the implementation of a project it is very rare to find a project that goes exactly as planned. Generally, they experience delays from what was planned, both in terms of time and progress of work, but there are also projects that experience acceleration from the initial schedule planned. The research objectives were to determine time and cost performance, and to determine cost estimates and final project completion time for the Well Pad stockpiling and compaction project in the Rokan Riau Oil and Gas Block environment. The method used in this study is the Earned Value method which combines the elements of cost and time as well as the physical performance of the work. The data obtained from the project includes the project time schedule, budget plan (RAB), project weekly reports and actual costs, then an analysis of costs, schedules, variances and performance indexes is carried out by explaining the problems that arise during the research. Based on the results of the analysis and discussion, the calculation of the CPI value is> 1 from the 1st week to the 16th week. This means that from the 1st week to the 16th week, the project cost is more economical. The EAS calculation for the 16th week estimates the project completion time is 116 days or 16 weeks. This means that the project is experiencing a delay from the planned schedule. At the end of the review period, an estimated final project cost of Rp. 4,022,024,000.00. And the estimated time for project completion is 116 days, which means the project will be completed in a longer time than planned, which is 211 days.

Abstract

Law enforcement discretion is an essential instrument in judicial practice that provides flexibility for judges or law enforcement officials to make decisions based on juridical, moral, and propriety considerations, outside of rigid legal provisions. One of its strategic applications is in prejudicieel geschil, which is a mechanism to postpone the examination of criminal cases until there is a civil case decision that has a substantial relationship with the subject matter of the criminal case, which aims to prevent contradictions in decisions between courts. This mechanism is regulated in Supreme Court Regulation Number 1 of 1956 and Supreme Court Circular Letter Number 4 of 1980, which distinguishes two forms of prejudicieel geschil, namely question pre judicielles a l action (mandatory delay) and question prejudicielles au judgement (facultative delay). Based on normative legal research with a statute approach and conceptual approach. Keywords: Discretion, Law Enforcement, Prejudicieel Geschil

Abstract

The solution to the transportation problem lies in assessing the performance of related road sections and intersections, and analyzing different traffic management schemes to optimize efficiency. This study aims to compare the performance of a road network simulation model for the Pahlawan road area. Data analysis includes examining origin-destination matrices, vehicle free speeds, vehicle behavior, and intersection control. The simulation model, calibrated and validated using Vissim, represents real-world conditions. Implementing SLFF (Single Lane Free Flow) and MLFF (Multi Lane Free Flow) systems at toll gates (scenarios 1 and 2) reduced queues, particularly at the Pancasila Monument Roundabout and Jalan Jati Raya. Adding a new toll gate via Jalan Kahuripan further improved traffic on Jalan Pahlawan compared to scenarios 1 and 2. However, converting the Gelora Delta roundabout into an underpass without additional measures worsened toll gate queues. Effective traffic performance can be achieved by combining the Gelora Delta roundabout underpass with either the SLFF toll payment system (scenario 5), MLFF (scenario 6), or the addition of a new toll gate (scenario 3).

Along with population growth and rapid development in Bandung Regency, demand for clean water is increasing. The development of a clean water supply system for Perumda Drinking water Tirta Raharja certainly requires a study of the feasibility of investing in the development of a drinking water supply system (SPAM) from the Cibulakan spring of Perumda Drinking Water Tirta Raharja, Bandung district so that it can be known to what extent the process is beneficial for the community and of course for the Government. The settlement method in this calculation for Feasibility Investment Analysis uses the Net Present Value (NPV) method and the Break Event Point (BEP) method. From the results of the investment feasibility analysis from the financial aspect with the Net Present Value (NVP) investment assessment, an NPV value of IDR 518,181,911,866 (NPV > 0) was obtained. So, the development of a Drinking Water Supply System (SPAM) from the Cibulakan springs of the Tirta Raharja Drinking Water Company, Bandung Regency is worth continuing. An NPV value that is positive or greater than (> 0) indicates that the income is greater than the value invested. The results of the Break Even Point (BEP) investment assessment showed that the return value occurred in the 14th year with the accumulation of negative profits being marked as positive after the 14th year. This explains that the investment in developing a Drinking Water Supply System (SPAM) from the Cibulakan springs of Perumda Drinking water Tirta Raharja in Bandung Regency is worth running, because there is a return on investment as proven by the BEP value for 7 years.
