Abstract

Clean water is water that is used for daily needs and becomes drinking water after being boiled first. The distribution system is a system that is directly related to consumers, which has the main function of distributing water that has met the requirements to all service areas. In addition to the problem of the clean water supply system, the problem of the capacity of the clean water treatment system (IPA) is also an obstacle with the continued growth of the population in the future. The need for clean water that meets health standards continues to increase every year, which is also experienced by Sangatta City which is in line with the increase in population and public awareness of health. Based on the background of this problem, the title of this study is Feasibility Analysis of Investment in the Clean Water System of Perumda Air Minum Tirta Tuah Benua Kutai Timur Sangatta City. The solution method in this calculation for the Feasibility Investment Analysis uses the Net Present Value (NPV) method, the Break Event Point (BEP) method. From the results of the analysis, it was obtained that the NPV value was Rp 29,586,543,082 (NPV> 0). So the investment in developing the production capacity and clean water network of Perumda Air Minum Tirta Tuah Benua, Kaliorang District, is feasible to continue. A positive NPV value or greater than (> 0) indicates that the income is greater than the invested value. The return value is obtained in the 9th year, marked by the accumulation of minus profits becoming positive after the 9th year. This explains that the investment in replacing the clean water distribution network of Perumda Air Minum Tirta Tuah Benua, Kaliorang District is feasible to run, because there is a return on investment as evidenced by the BEP value for 9 years.

Abstract

Dr. Soetomo Street drainage channel in Samarinda often experiences flooding during the rainy season. With the existing puddles, it will disrupt the activities of the surrounding community. If the puddle problem is not resolved, it can cause a bigger disaster that harms the local community. If the puddle problem is not resolved, it can cause a bigger disaster that harms the local community, both property and lives. Dr. Soetomo Street is one of the roads in Samarinda City that still often experiences puddles due to drainage channels that cannot accommodate or drain surface water. This research was conducted with the intention of controlling costs using the earned value method. The research method with calculations and analysis using the Earned Value Analysis Concept. The project cost performance did not match the budgeted costs in the 14th week, the costs incurred were Rp. 6,728,308,349 with an actual weight of 59.25%. The calculation of the CPI value <1 from week 1 to week 12. This means that the project from week 1 to week 14 cost more than planned or the project was more wasteful. At the end of the review period, namely week 12, the estimated total final project cost was Rp. 6,728,308,349, taken from the EAC value. If the tendency of the project performance condition is the same as at the end of the review, namely week 12, the estimated value does not exceed the project plan cost of Rp. 4,750,000,000.

Abstract

Water is a very vital natural resource and is needed to determine the sustainability of life of all living things on this earth. The problem faced is that the clean water system to residential areas is not smooth, to overcome this, a good clean water distribution network and good clean water system management are needed and are able to serve the clean water needs of residents in the area. In order to realize this, a fairly large investment is needed. One of them is by implementing company investment in the form of increasing the capacity of the raw water supply system. Based on the background mentioned, the title of this study is Feasibility Analysis of Clean Water System Investment at Perumda Air Minum Tirta Tuah Benua Kutai Timur, Kaliorang District. The solution method in this calculation for Feasibility Investment Analysis uses the Net Present Value (NPV) method, the Internal Rate of Return (IRR) method. From the results of the analysis, it was obtained that the NPV value was IDR 4,627,419,730 (NPV> 0). So the investment in developing production capacity and clean water networks at Perumda Air Minum Tirta Tuah Benua, Kaliorang District, is feasible to continue. A positive NPV value or greater than (>0) indicates that the income is greater than the invested value. The IRR value obtained is 15.50% > 10% (the minimum expected interest rate), so the investment in developing the production capacity and clean water network of Perumda Air Minum Tirta Tuah Benua, Kaliorang District is feasible to be implemented.

Abstract

In Indonesia, Building Maintenance Guidelines have been stipulated in the Regulation of the Minister of Public Works No. 24/PRT/M/2008 concerning Guidelines for Building Maintenance and Care. The construction of the office building of the KARHUTLA workshop of UPTD KPHP Berau Barat is certain to increase every year, of course it must be followed by good and planned management, not only construction costs but there are important costs that need to be considered as a reference for managers to run and operate the building, namely planning the future costs of the building itself including operational costs, maintenance costs and replacement. The Life Cycle Cost (LCC) method is one part of the building management and maintenance strategy. From the background of the problem, a study was conducted entitled Analysis of Maintenance Based on Life Cycle Cost in the Office Building of the KARHUTLA Workshop of UPTD KPHP Berau Barat. The solution method in this calculation is for Investment Feasibility Analysis using Initial Cost Analysis, Operational Cost Analysis, Maintenance and Care Cost Analysis, Demolition Cost Analysis. From the results of the analysis, it was obtained that there were three groups that compiled the Life Cycle Cost analysis plan for the UPTD Berau Barat workshop building, namely, initial construction costs, operational costs, maintenance costs and demolition costs. The initial construction cost of the UPTD Berau Barat workshop building cost Rp2,515,780,000.00 (48%), operational costs of Rp870,000,000.00 (17%), maintenance and care costs of Rp1,601,275,363.86 (30%), demolition costs of Rp251,178,000.00 (5%). The total Life Cycle Cost of the UPTD Berau Barat workshop building for 25 years is Rp5,234,233,363.86. In operational costs, the largest cost is the utility cost of Rp540,000,000.00 (62%) followed by employee salary costs of Rp330,000,000.00 (38%). In terms of maintenance costs, the largest costs are architectural costs of Rp. 1,433,035,692.66 (92%), followed by mechanical & electrical costs of Rp. 123,719,815.22 (8%).
