Abstract

The reliability of the electric power distribution system refers to its ability to provide sufficient electricity supply to consumers with satisfactory quality. There are several methods used to calculate the level of reliability of a distribution system, such as the Section Technique method and the Reliability Index Assessment (RIA) method, by considering reliability index values such as the System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), and Customer Average Interruption Duration Index (CAIDI). This study analyzed the reliability of the 20kV distribution system in the Prajurit feeder at the Balaraja main substation. Based on the analysis using the Section Technique method, the reliability index values for the Prajurit feeder were obtained at 2.1876 for SAIFI, 20.9624 for SAIDI, and 9.5823 for CAIDI. The analysis using the RIA method showed reliability index values of 2.2025 for SAIFI, 21.3445 for SAIDI, and 9.6910 for CAIDI. The reliability of the distribution system was also tested using computer simulation, and the reliability index values were found to be 1.5697 for SAIFI, 18.6939 for SAIDI, and 11.9092 for CAIDI. Therefore, based on the analysis, simulation, and reliability index standards stated in SPLN 68-2: 1986, the electric power distribution network in the Prajurit feeder can be categorized as a reliable network.

Abstract

Extreme event is a short scale rare phenomenon, but it has a quite a serious impact on the various  aspects of life. Studies on the prediction of extreme rainfall that occurred in the  region is needed to minimize the adverse effects of global climate, so the farmers and stakeholders will have a good knowledge about the climate. It is especially extreme  rainfall  events so anticipation  can  be  done early, than  the  production of  rice plant can be maximized and the losses can be minimized. To fulfil these needs, it requires statistical methods that can explain  the extreme  rainfall.  Extreme Value Theory is a statistical  method to identify extreme events. For data rainfall, snow, river flow, or temperature are classified as spacial data being a multivariate data because it’s observed in several locations, and therefore Spatial Extreme Value Method is developed. In the case of Spatial Extreme Value, the approach is often used Copula approach and max-stable process. Copula approach assumes that marginal distribution of extreme values follow a uniform  distribution. Therefore, this study discusses the Spatial modelling of Extreme Value with Copula approach in one of East Java's rice production centres is Ngawi Regency. It is hoped that the method will improve the accuracy of predicting extreme events.

Abstract

Natural fiber reinforced composites are widely applied to equipment with materials that have a combination of two basic properties, namely strength and lightness. This study aims to determine the optimum ability of kenaf stem fiber and tobacco stem fiber which contain relatively high cellulose to be used as soundproofing materials and also to utilize tobacco stems which were originally considered as agricultural waste to become a more useful raw material. Comparison of stem fiber ratio kenaf and tobacco stem fiber 100:0, 60:40, 50:50, 40:60, and 0:100. From the research results obtained, the composite exhaust produces the smallest sound, namely 81.6 dBA at a fiber ratio variation of 60:40 at 1500 RPM and produces the biggest sound, namely 99.1 dBA at a fiber ratio variation of 0:100 at RPM 3500. Results it can be said that the damping of the composite exhaust is quite good because it is not too far from the quality standard threshold of 83 dBA. The ability of kenaf stem fiber to reduce noise is better than that of tobacco stem fiber because the cellulose content in kenaf stem fiber (by 50%) is higher than that of tobacco stem fiber (by 37%).

Abstract

The dc output voltage of the solar cell is regulated due to changes in the intensity of sunlight shining on the surface of the solar cell, so that in the treatment of storing the dc output voltage of the solar cell to an external electrical load energy saver becomes unstable. Testing the occurrence of regulation of the dc output voltage of the solar cell expressed as the Vo(cell) parameter is carried out by changing the distance of the white light intensity irradiation from the LED lamp to the surface of the solar cell. The research method of adding a dc-dc converter device to the output part of the solar cell produces a stable dc output voltage parameter from the dc-dc converter device. The results of the research on charging energy storage on HP charge batteries using (1) the output voltage supply without the dc-dc converter parameter Vo(cell) obtained the results of charging the electrical energy load of the hp charge battery at Wb1(bat.) = 1.408 watt.hours and ( 2) The use of the supply voltage output Vo(conv.) from the dc-dc converter results in charging the electrical energy load for charging the battery charge hp reaching Wb2(bat.) = 1.426 watt.hours. There is a difference in the length of time it takes for the results of electrical energy to fill the cell phone charge battery using an output voltage source supply originating from a dc-dc converter regulator compared to an output voltage source without using a dc-dc converter regulator.

Abstract

Providing a return line for short-circuit currents or fault currents to a low-resistance ground, grounding system is useful for achieving a uniform potential voltage over a given area of buildings and equipment. Because a large voltage difference can occur if a fault current is forced to ground against a high resistance. Placement of the electrode to be planted is one of the elements to obtain a low grounding resistance value. Grounding resistance measurements, which will serve as a guide for the grounding system design process, are required during the planning stage for certain types of grounding systems. The problem is how the grounding resistance is affected by the buried depth of the rod conductor and the soil type resistance. Therefore, it is very important to conduct research and testing to determine the extent to which these parameters influence. The experimental results of measuring resistance on dry and wet soils are on dry soil 30 cm obtained 98.48 Ω, 60 cm obtained 37.07 Ω, 90 cm obtained 20.52 Ω, 120 cm obtained 19.77 Ω, and for wet soil at a depth of 30 cm obtained 43.34 Ω, 60 cm obtained 22.21 Ω, 90 cm obtained 15.43 Ω, 120 cm obtained 11.66 Ω.  So to get the 5Ω value we make an estimate by adding a depth of 56.603 cm for wet soil and 38.58 cm for dry soil, then the length of the electrode needed is 176.603 cm for wet soil and 158.58 cm for dry soil.
