In Bali, especially at Tiga Nusa, the need for electricity is increasing along with the development of the construction of resorts and hotels. In this study, a sample of cases was taken in 2014 regarding the Lembongan feeder network system which was still installed with several LBS (Load Break Switch) which used to localize interference. Therefore, to anticipate interference and improve the reliability of feeders, one of many ways is to add an automatic back cover (recloser). This study aims to determine the optimal recloser location in the Lembongan feeder by using a combined method of fuzzy logic and particle swarm optimization with the help of MATLAB software. The results of this study obtained the best location of the recloser in group 5, namely the area between LBS SD 3, LBS Celagi Empak, and LBS Lembongan by adding one recloser. The SAIFI value is 1,9471 times / customer / year and the SAIDI value is 1,4596 hours / customer / year where the world class service parameter standard for the SAIFI reliability index is 3 times / customer / year and the SAIDI reliability index is 2,5 hours / customer / year.

An electric power system will get overload disturbance if a plant that was previouslyable to supply power to a system that is outage, causes other plants that are still operating tohave the entire load of the system. This study aims to see the performance of under frequencyrelay (UFR) that has been installed in the Bali system in overcoming overload disturbances,namely in the form of generator outages according to the scenario that has been made. Themethod used is to model the load shedding scheme using UFR in software and run according tothe scenario. The scenario referred to is a disturbance that causes one or more generators toexperience blackouts due to disturbances. The results of the analysis show that under thefrequency relay (UFR) installed in the Bali system it cannot return the system frequency to itsnormal state, namely the system has a shortage of generating power with a steady statefrequency below 49.8 Hz in the 3rd, 4th fault scenarios. , and the 5th while the system hasexcess power generation with a stable state frequency above 50.2 Hz at the 9th and 10thdisturbances.

The need for electricity in this global era is increasing, so that a more reliable electrical system is needed. A reliable system cannot be separated from interference, so there needs to be a system reliability analysis and power loss to the feeder by configuring the network. This research was conducted to find the reliability index value in the form of interference frequency and duration of interference (SAIFI and SAIDI). In one Tabanan feeder the results obtained exceed the standard so reconfiguration is performed Based on the analysis obtained before reconfiguration, the reliability index for SAIFI is 6,7456 (failure / year) and SAIDI is 11,4767 (hour / year) and power loss by 6,27 %. After reconfiguration of Tabanan feeder, the reliability index was better, for SAIFI is 5.2475 (disturbance / year) and SAIDI is 9,8798 (hour / year), the power loss was 2.82%. Sanggulan feeder is a new feeder reconfiguration result from Tabanan feeder, where the analysis was carried out to find out the reliability index of Sanggulan feeder, it was obtained the SAIFI value of 4.5753 (disturbance / year) and SAIDI of 9.5297 (hour / year) and power loss of 4,80%.

Energi alternatif merupakan sumber energi terbarukan, contohnya seperti matahari, angin, air, biomasa dan panas bumi. Energi pasang surut merupakan pemanfaatan energi yang dihasilkan dalam perpindahan massa air akibat pasang surut dengan efek rotasi bumi dan gravitasi bulan. Energi ini banyak terdapat diselat karena pada selat terjadi penyempitan ruang gerak arus sehingga kecepatan arus menjadi lebih cepat. Salah satunya adalah Selat Pulau Serangan. Tujuan penelitian ini adalah mengetahui potensi energi listrik dan kerapatan daya di Selat Pulau Serangan. Pengukuran arus laut menggunakan metode Lagrange dan alat Current Meter di delapan titik penelitian, kemudian dengan metode Regresi Sederhana Deret Waktu untuk meramalkan ketinggian air. Hasil perhitungan menunjukkan bahwa energi yang dihasilkan saat pasang mencapai 248,028046 kilo Joule selama 24 jam, sedangkan saat surut mencapai 251,8062 kilo Joule selama 24 jam. Untuk rapat daya terbesar berada disekitar jembatan berkisar 25,3604 – 47,05809 W/m2, sedangkan rapat daya terkecil berada di sebelah utara jembatan berkisar 0,012069 – 0,121019 W/m2.

Electric load in Sumbawa Besar Regency from 2011 - 2018 experienced an average increase of ± 6.6%. The electric load for the following year is not yet known, so forecasting is needed. Electric load forecasting has an important role in the energy management system. Many methods can be used for forecasting, one of them is the fuzzy logic method. Fuzzy logic method consists of 3 components, those are Fuzzification, Fuzzy Inference System, and Defuzzification. Fuzzification is an important component of the fuzzy logic method, so the proper configuration is needed in order to produce forecasting that is close to the actual data. The simulation was carried out in 3 conditions, those are the first conditions (3 membership functions), the second condition (5 membership functions), and the third condition (7 membership functions). The third condition obtained a MAPE value of 2,42%, while the second condition was 3,34%, and the first condition was 6,51%. The third condition obtained the simulation results in 2026 at 24,75MW, while the second condition was at 23,26 MW, and the first condition was at 20,97MW. The third condition is the best condition in this study, because it has the smallest MAPE value.
