Abstract

Along with the grave of the population of Denpasar City more especially the South Denpasar sub-district from year to year resulted in an increase in the amount of clean water needs. The increase in clean water needs is certainly necessarily anticipated early to avoid the potential lack of clean water in the future. For this reason, a study is needed to find out how the estimated clean water needs in the next future 10 years. Before calculating, first is to know the estimated population in the next 10 years or 2030. To calculate data on the number of population in the last five years to find the average population growth. Using the geometry method, then calculated the estimated population in 2030. The result is, the population in 2030 was 408499 people. Meanwhile, data is also needed related to the current average of clean water. The data was obtained through a survey using the questionnaire method. The sample in this survey was determined using the Slovin formula, where the number of PDAM water customers in 2020 was 19788 home connections and by using a tolerance limit of 10%, then the number of respondents was 100 home connections. Of the 100 respondents, the result is the average use of clean water of 120 liters/person/day. With this data, the need for clean water needs in the next 10 years with service coverage is 80% of the total population. The result is, the total clean water requirement in 2030 was 668.7756 liters/second. With this enormous need, water sources are needed with high production capacity to meet the needs of 2030.

Abstract

Time and cost are very influential on the success and failure of a project. Benchmark for project success is seen from the short completion with minimal costs without leaving the quality of the work. Systematic project management is needed to ensure that the project implementation time is in accordance with the contract or even faster so that the costs incurred can provide benefits. The purpose of this study was to determine the performance of the Balai Serbaguna project in terms of project costs and time. Performance analysis on the construction project of the Multipurpose Hall in Tabanan district using the Earned Value Management (EVM) Method. The Earned Value Management method uses three indicators in its calculation, namely: ACWP (Actual Cost Work Performance), BCWP (Budget Cost Work Performance), BCWS (Budget Cost Work Schedule). Project performance can be seen from the calculation of the CPI (Cost Performance Index). During the 8 weeks of the project implementation, it can be seen that the CPI performance in weeks 1, 2, 3, 7, and 8 of the CPI is <1, which means that the project implementation budget is greater than the planned budget, so the project is said to be not good in terms of costs. At week 4 and 5 the CPI is worth> 1, which means that the project implementation budget is smaller than the planned budget, which can be said to be good in terms of costs.
