Nelayan tradisional adalah nelayan yang menangkap ikan pada malam hari, menggunakan perahu kecil. Nelayan menggunakan lampu sorot halogen yang dicatu dengan genset kecil, untuk menarik perhatian ikan. Kendala yang dihadapi nelayan yaitu harga minyak yang semakin mahal, kelangkaan minyak, getaran dan suara berisik dari genset yang membuat ikan takut mendekat, konsumsi energi yang tinggi dari lampu sorot halogen, serta polusi udara dan emisi karbondioksida dari penggunaan genset. Solusi yang ditawarkan yaitu mengganti genset dengan PLTS. PLTS yang dirancang yaitu, 2×80 ???????? modul surya dirangkai seri, 10 ???? charger controller dan 2×70 ????? baterai dirangkai seri untuk menyuplai 4×30 ???? lampu sorot LED. PLTS ini mampu memenuhi kebutuhan energi sebesar 174,52 kWh/tahun, dari 175,2 kWh/tahun, jadi sebanyak 99,6 % kebutuhan energi telah mampu disuplai. Investasi awal sistem PLTS ini yaitu 10.639.500 rupiah, dengan pengurangan emisi karbondioksida sebesar 63.291.569 ????????/?????????????????.

Disruption of short circuit flow of one ground phase that occurred on the transmissionline 150 kV Nusa Dua-Pesanggaran Substation, causing blackouts to occur in the Nusa DuaSubstation area extending to the surrounding area. The disruption that occurred failed to besecured because the GFR (Ground Fault Relay) relay could not detect the presence of a currentinterference so it failed to work. Assisted relays are needed to secure short circuit flowinterference one phase to help the GFR relay, where the selected relay is the DEF (DirectionalEarth Fault) relay. Installation of auxiliary relays requires planning and relay setting steps toobtain Iset, TMS and trip time. Calculations that have been done get the results of the GFR relayworking at a minimum interference of 1,200A while the DEF relay works at a minimuminterference of 0.521A. The one-phase disruption detected on the 150 kV channel based on thesimulation is below 300A. Def relay will work after the GFR relay does not manage to detectinterference of one phase of the land with a time span of 0 - 0.3 seconds.

Energy needs are increasing from year to year in line with the increasing population,economic growth, and high energy consumption. More than 86% of the world's energy todaycomes from fossil fuels, while the world's energy demand is increasing. One of theconsiderations for overcoming pollution caused by fossil fuels is to seek alternative energysystems. More than 90% of the energy that affects greenhouse gas emissions is the result ofburning fuels globally. Exhaust Fan is a good system for wind power extraction. This air exhaustsystem is suitable for power plants with wind turbines as a drive where the resulting wind speedis higher and consistent when compared to natural wind, but has turbulent characteristics. Thiswind is not good for the wind turbine. A honeycomb is a tool used to reduce this turbulentcharacteristic. The results obtained by the addition of a hexa type Honeycomb to the exhaustfan with a speed of 6m/s using a savonius type turbine, there was a decrease in turbine speedwhich was previously unstable between 952 to 1007 rpm to 866 rpm and the generator outputpower decreased by 0.3 watts. The addition of Honeycomb makes the turbine rotate speedstable at 866 rpm and the wind flow becomes laminar.

Permasalahan gangguan di jaringan distribusi 20 kV seringkali menyebabkan terputusnyapasokan daya listrik kepada pelanggan. Salah satu penyebab keandalan sistem kurang baik adalahkesalahan koordinasi setting relay pada penyulang. Seperti yang terjadi pada penyulang Ngurah Rai Idan Penyulang Ngurah Rai II dimana terdapat kesalahan koordinasi setting antara relay pada pangkalpenyulang yang terletak di Gardu Induk (GI) dengan relay pada di ujung jaringan yang terletak diGardu Hubung (GH). Untuk memecahkan masalah tersebut maka perlu dianalisis setting relay yangsudah ada (eksisting). Untuk membuktikan koordinasi setting relay sudah sempurna, maka akandilakukan simulasi menggunakan bantuan program computer yaitu Electrical Transient AnalysisProgram (ETAP). Dari hasil analisis diperoleh nilai setting dimulai dari setting Over Current Relay(OCR) pada pangkal penyulang (GI) 360 A dan Tms 0,36 sedangkan untuk nilai setting arus OCRpada ujung penyulang (GH) yang menggunakan relay directional 330 A dan TMS 0,16. Kemudianuntuk setting GFR pada pangkal penyulang (GI) diperoleh nilai 34 A dan TMS 0,2. Sedangkan settingGFR pada ujung penyulang (GH) yang menggunakan relay directional diperoleh nilai 31 A dan TMS0,1.

Penelitian ini mengembangkan piranti Self-Stabilizing 2-Axis menggunakan accelerometer ADXL345 berbasis mikrokontroler ATmega8. Piranti ini terdiri dari dua frame yaitu frame-stabil dan frame- bebas. Frame-stabil difungsikan untuk menunjang beban dan frame-bebas untuk menerima input perubahan kemiringan. Seluruh komponen elektronik dan mekanik ditempatkan pada frame-bebas guna mengurangi beban pada frame-stabil. Accelerometer ADXL345 diimplementasikan untuk mendeteksi kemiringan (x,y). Dua motor servo digerakan mikrokontroler berdasarkan nilai sensor untuk mencapai posisi stabil. Penelitian ini mendapatkan bahwa piranti Self-Stabilizing 2-Axis mendeteksi kemiringan dan menampilkan nilai kemiringan pada Liquid Crystal Display serta dapat menstabilkan frame-stabil ketika bagian luar alat mengalami perubahan kemiringan dari +90o hingga -90o. Hasil pengujian beban maksimal ±750 gram. Self – Stabilizing 2-Axis mendeteksi kemiringan dengan kesalahan 0,45 % pada sumbu X dan 0,05% pada sumbu Y.

Abang feeder receives electricity supply from transformer II 30 MVA GI Amlapura with a line length of 23 kms and has 67 distribution substations with data losses of 0,574 MW. Reducing losses, increasing reliability and continuity, one way to do this is to reconfigure feeders. The feeder reconfiguration will affect the value of the feeder impedance, so the resetting of the Over Current Relay, Ground Fault Relay and Recloser protection systems is needed. Resetting the protection of Amed OCR feeder obtained t value = 0.1 seconds, OCR recloser Tirtagangga obtained t value = 0.2 seconds, and Oang feeder Abang obtained t value = 0.3 seconds. Resetting the protection of the Amed GFR feeder obtained a value of 0.1 seconds, GFR recloser Tirtagangga 0.2 seconds, and GFR feeder Abang 0.3 seconds. The simulation results using the ETAP program are known to coordinate OCR, GFR and recloser already working well with grading time values ? 0.3 second, so it will not cause overlap or trip simultaneously.

Utilization of waste energy from exhaust fan air needs to be optimized considering thereis great potential where exhaust fan is widely used in the industrial sector. Exhaust wind fromexhaust fan can be utilized to generate electricity with horizontal wind turbine. Thecharacteristics of exhaust energy from exhaust fan that spreads and has medium to low speed,therefore its requires an optimization to get maximum wind energy from exhaust fan, one ofthem by the addition of a diffuser that can increase the performance of wind turbines byfocusing the wind around the rotor. Designing diffuser conducted using AutoDesk Inventor andsimulation CFD (Computational Fluid Dynamic) with SolidWorks. The results of this studyindicate, horizontal wind turbine with diffuser can increase wind turbine power up to 47.61% andincrease turbine rotational speed (rpm) up to 23.48% compared to wind turbines without adiffuser.
