Abstract

ABSTRACT Achievement of the performance of the 2017 contract target of PT PLN (Persero) Central Kalimantan UIP, namely 54 contracted procurement packages and in 2018 there were 57 procurement targets with a temporary budget ceiling of Rp. 1,501,933,269,600.00. So as to achieve the 2018 contracted procurement target it will have an impact on the achievement of the 2019 Commercial Operation Date (COD) efforts needed to accelerate the implementation of goods and services. One of the basic knowledge (common knowledge) for acceleration in a knowledge management construction starts from adding three elements, including: labor, equipment, and overtime / overtime. After a Root Cause Problem Solver (RCPS) and priority scale selection process are carried out, two priority Problem Solving results have never been implemented as an effort to accelerate implementation, namely Parallel Work with Person In Charge (PIC) Method and Monitoring of Procurement Implementation Schedules with S-Curve Analysis . Keywords:Contracted, Person In Charge (PIC), Package, IDR (Rupiah).

Abstract

One of the effects of reduced transformer life is the frequent occurrence of disturbances, disturbances that can occur in the form of contamination of insulating oil which has an impact on transformer damage. To reduce the damage, a research was carried out, in this study it was carried out to see the effect of water contaminants contained in the insulation of transformer oil using the Breakdown Voltage method by looking at the value of the translucent voltage. There are 2 types of insulating oil used during testing, mineral, and vegetable oil, while the test equipment used is the BAUR Oil Tester DPA, with the standard IEC 60156:2018 test equipment. Which is adapted to the standard specification SPLN 49-1:1982 which states that new oil has a breakdown voltage value of 30 kV/2.5 mm. The results of the test show that the breakdown voltage value is influenced by water contaminants where the more contaminants contained, the faster the breakdown voltage value will decrease. This research can be an indication to maintain the transformer resistance.

Abstract

The negative impact of fossil-fueled plants and the lack of public understanding of renewable energy lies behind the holding of these PKM activities with the aim of educating and at the same time transferring technology that is directly beneficial to the community in the form of solar powered street lighting. From the surveys that have been conducted where there are no available street lighting facilities so that there are some community activities that are difficult to do at night. From this work, there were two important things, among others, that the community gained an understanding of renewable energy and knowledge to efficiently use energy to reduce the environmental impact of the dominant fossil power plant in Indonesia. The second is that with the help of solar-powered street lights, the community is very helpful in carrying out activities at night and creates more secure conditions in the community.

Abstract

Renewable energy resources are currently being developed in Indonesia. The government is also targeting renewable energy mix of 23% to be achieved in 2025. Solar Photovoltaic Generation System is one of a form of renewable energy that is currently being developed in Indonesia. Several industrial estates in Indonesia are filled with factories with fairly large buildings and have great potential for the development of Rooftop Solar Photovoltaic with the advantage of reducing land investment costs and of course without reducing the functionality of factory operational. The purpose of this research is to simulate the technical and economic performance of Solar Photovoltaic on grid 200kWP installed on the roof of a factory building using Helioscope software in an industrial estate area in West Java. The simulation results show that the average value for Global Horizontal Irradiance (GHI) is 138.2 kWh/m2, Electrical Energy Production is 21,977 kWh, and the Performance Ratio (PR) in one year is 78.06. Meanwhile, the total annual Electrical Energy Production is 263,723.6 kWh. The total investment value of the Rooftop Solar Photovoltaic on Grid system in this factory building is Rp. 2,457,850,800. Based on the economic feasibility study made, it can be concluded that the Rooftop Solar Photovoltaic on Grid system with a power of 200 kWP in the factory building is economically feasible as long as the interest rate is less than 12.71% (Internal Rate of Return/ IRR).

Abstract

Environmental damage can be caused by an imbalance of the earth’ constituent elements, which one of the elements is scarcity of clean water in the earth. Dearth of clean water is predicted that will be experienced more than a half of word population of nine million of human being in 2050. The phenomenon of the scarcity of the clean water has been occurred especially in Indonesia that it is a country which has six percent of the potential of the clean water, but in fact it shows the need of the clean water of Indonesia population are still not enough. The dearth of the clean water needs to get serious attention from all stake holder, included people in the boarding school. An effort to decrease the scarcity of the clean water rate is by behaving frugally in using the clean water. To do that need to do socialization massively to the people and it require a long time. Therefore, beside the socialization massively, engineering to decrease the flow rate in using the clean water through the valves that is by applicating flow control method. This simple technology of flow control application, the community service team and Nurul Haramain boarding school located in Kampung Saitem, Ciburayut, Cigombong, Bogor, West Java are collaborated. A measurement result of flow rate before the flow restrictor is applicated in the valve is 7.76 liter/minute and after applicated decrease to 1.13 litter/minute. Percentage of decreasing is to reach 83 percent.

Abstract

Renewable energy is growing, one of which is by controlling solar energy. A solar power plant (PLTS) is a power generation system that utilizes solar energy to become electrical energy through photovoltaic modules, which are included in environmentally friendly energy so that it becomes a renewable, effective, more efficient, and reliable plant. The research designing the modeling of PLTS on a grid was carried out on the roof of a gas power plant (PLTG) which generated 164.47 MWh / year. Analyzing modeling in the addition of the Rooftop Solar System that enters the network can reduce exhaust emissions from the use of other equipment for four years with an average of PLN by 99.29%, PLTG #1 by 99.06 and PLTG #2 by 99.11%. The impact of the addition of the PLTS Rooftop on the quality of power entering the 3.3 kV network system is seen that the feeder 2-panel bus has improved to 97.82% of the voltage drop of 72.67% in line with the PLN 3 panel, the improvement is made by providing capacitors of 3x4Mvar. Feeder 3 improved to 97.61% of the voltage drop of 78.87%, in line with the PLN 4 panel. The improvement was carried out by providing a capacitor of 2x4Mvar. Panel feeder four was seen to have improved to 99.21% from an excess voltage of 109.23% in line with the generating equipment, and the improvement was made by reducing capacitors by 0.1 Mvar from the used 5x0.1 Mvar.
