Abstract

Along with the very rapid development of infrastructure and construction in Indonesia in the era of globalization, the Indonesian government has carried out various large-scale projects to achieve the increasingly complex expectations of society. This will trigger the growth of the construction industry in Indonesia and become one of the main goals in the framework of national development. An infrastructure development project is an activity carried out with limited time and resources to achieve a specified final result. One of the construction projects currently being developed is Road Works. The Earned Value method can be used to determine cost performance and implementation time during the project and the indicators used for analysis include: BCWP (Budget Cost of Work Performance), BCWS (Budget Cost of Work Schedule), ACWP (Actual Cost of Work Performance), SV (Schedule Variance), CV (Cost Variance), SPI (Schedule Performance Index), CPI (Cost Performance Index), EAC (Estimated At Complete) and ET (Estimated To Complete) and TE (Time Estimate). Conclusions from this research is to determine the estimated costs and time for project completion. In the data analysis in the 9th week, the project schedule performance (CPI) was 1.14, greater than 1, while (SPI) was 0.587, less than 1. The results of the calculation of projected costs for the remaining work (ETC) were IDR. 1,586,686,537.62 and total project costs (EAC) of Rp. 2,509,041,243.08.

Abstract

Project completion delays have adverse consequences on a contractor's credibility and result in additional penalty costs, reducing potential profits. To mitigate these issues and optimize project outcomes, refining activity schedules and budgets is crucial. The Earned Value Method proves effective in monitoring and controlling project activities. In the case of the Kediri airport access road construction project, weeks 1 to 6 revealed a negative Cost Variance (CV), indicating higher-than-planned costs, while weeks 7 to 8 showed a positive CV, suggesting costs were lower than anticipated. Schedule Variance (SV) for the 1st week was unfavorable, indicating a delay, and SV>1 from weeks 2 to 8 signaled a project delay. The Estimate to Complete (ETC) is IDR 17,470,510,292.77, and the Estimate at Complete (EAC) is IDR 32,509,153,464.05. The Time Estimate (TE) forecasts project completion in 89 calendar days, five days beyond the contracted 84 days. Employing the Earned Value Method enhances project performance evaluation and decision-making to avoid delays and cost overruns.

Abstract

One of the project types is the Construction Project. The main activity components of this type of project consist of feasibility assessment, engineering design, procurement and construction. In construction projects very often delays occur where the realization in the field does not match the schedule of the implementation plan, due to several factors that occur, even though a careful plan has been prepared but in practice in the field there are still many problems in implementation. The purpose of this study was to determine the cost and time performance in the implementation that took place from week -1 to week 17 on the Subali Bridge Construction project, Sutojayan Kec. (D.G.008), Blitar Regency using Earned Value. From the results of the analysis it can be seen that the costs incurred are lower than the planned costs, this can be seen in the CPI value of 1.28 while the implementation time is slower than the planned schedule indicated by the SPI value of 0.71. The results of the calculation of the estimated project cost of Rp. 8,214,904,015.36 with a budget plan of Rp. 10,502,000,000.00 there is an efficiency of Rp. 2,287,095.64 (21.78%). with an estimated completion time of 19.43 weeks, indicating that the project is delayed for 2.43 weeks from the planned 17 weeks.

Abstract

The construction project of the McD Pontianak building encountered significant challenges due to a tight schedule of 110 calendar days and unforeseen delays arising from the existing building's foundation. These delays led to a setback in the construction progress, prompting the need for strategic measures to accelerate the project and mitigate the delays amounting to 11.48%, equivalent to 12.63 days. The potential financial consequences of this delay were estimated at IDR 228,366,605. In order to expedite the construction process, the chosen acceleration method was the crashing method, involving an increase in overtime ranging from 1 to 4 working hours, in accordance with relevant laws and regulations. This required a comprehensive analysis encompassing normal cost, normal duration, critical path, productivity, crashing cost, and crashing duration calculations. Upon thorough examination, it was determined that the optimal solution to overcome the delays was to implement an additional 2 hours of overtime. However, this decision came with associated costs, resulting in a necessary expenditure of IDR 93,651,965 to achieve a crashing time of 18.30 days. Despite the increased financial commitment, this strategic approach was deemed essential to meet the project's original schedule and avoid potential penalties. The findings and conclusions drawn from this analysis provide valuable insights into effective project management and decision-making in the face of unexpected challenges in the construction industry.

Abstract

Jabung District is a sub-district located in the Malang Regency area of 135.89 km2 or around 4.56 percent of the total area of Malang Regency. This sub-district consists of 15 villages, including Argosari, Gadingkembar, Gunungjati, Jabung, Kemantren, Kemiri, Kenongo, Ngadirejo, Pandansari Lor, Sidomulyo, Sidorejo, Slamparejo, Sukolilo, Sukopuro, and Taji. With a population of 74,311 people in 2020, with a population density of 592 people/km2. In Jabung District, especially in 4 villages, including Pandansari Lor Village, Gading Kembar Village, Argosari Village, and Kemiri Village, there is currently a water shortage. Siuk Source Potential has water potential large enough to meet the standard needs in these 4 villages by gravity. From the results of instantaneous discharge measurements during the dry season in 2021, it can be seen that the discharge in Sumber Siuk is 65 l/sec, and the planned collection to fulfill these 4 villages is 20 l/sec. Construction of the broncaptering and raw water distribution network was built in 3 stages. Before the physical implementation of the installation of distribution pipes in stage 3, a trial run was carried out from stage 1 and stage 2.

Abstract

Implementation of construction projects often faces delays in work completion. Delays in project completion that exceed the time limit specified in the contract cause losses both from the contractor as the executor and the assignor. Project implementers pay more attention to the cost aspects incurred and often ignore the time control of project implementation so that project implementation often experiences delays in work. The purpose of this study is to analyze the time efficiency carried out by the provider from the beginning of the work, during monitoring, to the end of the project implementation. And estimate how much it costs from the start of work, when monitoring until the project is completed using the Earned Value Method. From the analysis, results and discussion of the Bondowoso Polije Campus Administration Building project, it can be concluded that the project work time exceeds 2,543 weeks for the total work and will experience a loss of Rp 393,323,318.10 from the reduction of the total contract minus the total financing. Therefore, the construction management proposes to shift the work schedule to work that does not require the achievement of the main construction. In addition, the contractor should communicate to the assignor of the Administration Building project to increase the duration of the administrative building construction project work. And participate in finding alternative suppliers of the main material without having to wait for the vendor to get the material needed.

Abstract

Sapodilla, also known as Manilkara zapota or sawo, is being studied as a potential natural remedy for diarrhea caused by Escherichia coli bacteria. The objective of this research is to investigate the inhibitory effects of sapodilla leaf extract on the growth of Escherichia coli bacteria. The method involves formulating sapodilla leaf extract at various concentrations and dividing them into seven groups, including positive and negative controls. The concentrations tested are 2%, 20%, 25%, 30%, and 50% sapodilla leaf extract. The results indicate that sapodilla leaf extract exhibits a mild inhibitory effect on bacterial growth, measuring 6.9 mm in the inhibition zone. Notably, the 50% concentration of sapodilla leaf extract demonstrates a moderate inhibitory effect, with a larger inhibition zone measuring 29.1 mm. This study sheds light on the potential of sapodilla leaf extract as a natural antimicrobial agent, providing valuable insights for further exploration and development of alternative treatments for Escherichia coli-induced diarrhea.
