Abstract

The quality of electricity supply at consumer’s side is highly affected by its distribution networks. The distribution system reliability can be determined by using a number of reliability indices. The most commonly used indices are SAIFI (Systems Average Interruption Frequency Index) and SAIDI (Systems Average Interruption Duration Index). The calculation of SAIFI and SAIDI requires probability of outage indices for installed power system equipment (λ).Calculation of reliability indices usually follows PLN Standard SPLN 59:1985. Within thestandard, the λ value for distribution line is divided into 2 categories, which are overhead and underground distribution lines. In fact, there are a number of conductor types used for distribution lines that may have different values of λ.This research is focused to a determination of λ values for AAACOC (All Aluminium Alloy Conductor Cable) and MVTIC (Medium Voltage Twisted Insulated Cable). Distribution system failure data is collected from a number of distribution lines in Bali. Data collection was carried out using a TMP (“Tingkat Mutu Pelayanan”/Service Quality Level) Recorder. Data analysis then carried out to calculate the λ values and the reliability indices.The new λ values for AAACOC and MVTIC are found to be 0.187 and 0.089/km/year, respectively. The results indicated that the new value of λ for AAACOC and MVTIC are more realistic and suitable for reliability analysis particularly in Bali Distribution Systems.

Abstract

Optimasi pemasangan dan kapasitas kapasitor shunt pada Penyulang Menjangan dilakukan untuk kompensasi daya reaktif pada jaringan distribusi primer sehingga dapat memperbaiki faktor daya, mengurangi rugi-rugi jaringan dan memperbaiki profil tegangan pada jaringan distribusi Penyulang Menjangan setelah dilakukan pemasangan kapasitor shunt. Untuk mendapatkan nilai yang optimum dari parameter-parameter tersebut, menggunakan proses optimasi dengan metode Capacitor Sizing – Radial Network. Dari hasil studi simulasi optimasi kapasitor shunt pada Penyulang Menjangan, diperoleh letak optimum dari kapasitor shunt pada jarak 92.724 ft (27,82 km) dari sumber atau jika digambarkan pada diagram segaris berada sebelum Bus 28 (GR 122) dengan kapasitas 1.800 kVAR. Setelah dilakukan pemasangan kapasitor shunt tersebut, faktor daya naik dari kondisi awal simulasi 0,79 menjadi 0,91, tegangan pada Bus 91 (GR 115) mengalami peningkatan sebesar 16,4% (dimana kondisi awal simulasi 75,05% naik menjadi 91,42%) serta penurunan rugi-rugi jaringan sebesar 29,3%.

Abstract

In communication systems using microwave waves (microwave links), the presence of noise and multipath fading can reduce and reduce the performance of communication systems. Microwave propagation is influenced by several things in the reception system besides having to LOS (Line of Sight) there is a reflected signal from the surface that is causing interference (multipath signal). By using the diversity maximal ratio combining technique on systems affected by noise and fading, it is used through BER (Bit Error Rate) analysis. The use of research simulations to determine the improvement of the system at the recipient by comparing before and after using the maximal ratio combining technique

Abstract

Abstract— Basically, building a system is to meet the needs of its users, where the system must consider the ease, comfort, and satisfaction of using the information system. Several studies have shown that these aspects can be measured through usability analysis. This research was conducted to analyze the usability of a project management information system developed and used at PT. Baliyoni Saguna Group. The purpose of this study is to determine the level of usability of information systems or usability by measuring four aspects of usability, Measurements are made using the Use Questionnaire which is measured using a Linkert scale with a scale of 5. So it is hoped that this research in the future can be a reference for companies to continue to develop information systems to support business activities and increase company competitiveness. The results of the study indicate that the Ayoowork Baliyoni information system has a good usability level with a score interpretation value of 62.07%. The scores of each aspect measured are usefulness with a score of 593 or 62.94%, ease of use 61.39%, ease of learning 60.59%, and satisfaction with 63.03%.

Abstract

Bali Regional Income Board is a regional organization tasked with determining the amount of local tax revenue target for the next fiscal year. Currently still done manually in accordance with existing upgrading trends from previous years. So it needs to be done in way that can be measured and accurate forecasting. In recent studies, it shows that forecasting by combining conventional and artificial intelligence (hybrid) methods results in better forecasting accuracy. By that reason, the writer tries to forecast the target of revenue from Motor Vehicle Tax (PKB and BBNKB), which contribute 70% to Bali Province income by combining ARIMA method and Genetic Algorithm. The data used consisted of five groups: yearly and new Vehicles that have linear data types, and as Reverse Names, Entrance Mutations and Output Mutations that have non-linear data types. Each data group consisted of PKB and BBNKB, where it’s monthly realization data from 2011 to 2016 used to be training data and realization data for 2017 as test data. The Combined forecasting mechanism is performed using ARIMA to forecast linear data and using Genetic Algorithms for non-linear data. As a benchmark for combined forecasting using ARIMA and Genetic Algorithms, forecasting using ARIMA and Genetic Algorithms independently is used for all data types (linear and nonlinear). Testing is done by comparing data of forecasting result with that 3 different methods for year 2017 with data realization year 2017. Then the error percentage is counted using MAPE. From the test results obtained for ARIMA MAPE value of 3.63, Genetic Algorithm 4.72 and combined ARIMA and Genetic Algorithm of 1.13. Thus, the result of forecasting with combination ARIMA and Genetic Algorithm have the best result and then used to forecasting target of PKB for 2018 and so on

Abstract

Penyambungan Distributed Generation pada sebuah jaringan distribusi menimbulkan dampak meningkatnya rugi-rugi daya yang diakibatkan lokasi penyambungan DG yang kurang tepat. Salah satu cara yang dilakukan untuk mengurangi rugi-rugi daya adalah penentuan lokasi penyambungan DG yang tepat dengan optimasi. Optimasi lokasi penyambungan DG pada Penyulang Bangli bertujuan untuk meminimalkan rugi-rugi daya pada system distribusi di Penyulang Bangli. Dari hasil aliran daya awal diperoleh nilai rugi-rugi daya pada sistem distribusi Penyulang Bangli sebesar 160,120 kW. Optimasi penyambungan DG ini menggunakan metode Particle Swarm Optimization. Metode PSO ini dipilih karena dapat menghasilkan nilai (hasil) yang lebih stabil sesuai dengan fitness yang dimasukkan. Hasil pengaplikasikan metode PSO pada sistem jaringan distribusi Penyulang Bangli, diperoleh lokasi penyambungan DG yang menghasilkan rugi-rugi daya minimum terdapat pada titik 123 (Tembuku 14) dengan rugi-rugi sebesar 108,870kW atau terjadi penurunan rugi-rugi daya sebesar 51,2kW jika dibandingkan dengan kondisi eksisting penyambungan DG dititik 210 (bangklet 1) pada Penyulang Bangli rugi-ruginya hanya mengalami penurunan sebesar 46,8 kW. Hasil yang didapat dari optimasi penyambungan DG menggunakan metode Particle Swarm Optimization memiliki nilai penurunan rugi-rugi daya yang lebih besar yaitu sekitar 32%.

Abstract

New and renewable energy has become the green energy trend in the electric power system going forward. The Bayu Power Station (PLTB) is one of the centers of electricity generation with a primary source of energy that is pollution-free and environmentally friendly. Currently in the South Sulawesi system, PLTB has operated with a total power of 70 MW at a base load of around 700 MW. Because PLTB is very dependent on wind conditions, the power generated becomes unstable and this has a significant intermittent effect on the stability of the system. The results of this study indicate that the intermittent composition of nuclear power plants is increasing from the April-July 2018 period. This ever increasing contribution disrupts frequency stability in the South Sulawesi system
