Get PDFAbstract– In this study, the off-grid solar system is used to support the lighting for the residents in Dusun Sedayu. Each house had a total lighting power of 12 Watt consisting of two lamps of 5 Watt and 7 Watt lamp respectively. The technical analysis conducted includes several supporting components such as: the examination of solar panel capacity of 700 WP, the examination of the used battery capacity of 500 Ah, the examination of the BCU capacity of 60 Ampere and the election of the inverter of 12VDC / 220VAC 500 Watt. The results of the economical assessment obtained of the system are as follow: daily average power (P) which can be raised for 10 hours (07.00 am to 17.00 pm) is equal to 337.96 Watt, the average energy per day (Eh) is about 3,3796 kWh, the energy price per unit from the off-grid solar system is about Rp.13.294,46, - / kWh, and the period of return on investment (payback period) of the off-grid solar energy system is about 4.01 years. By analyzing the Internal Rate Of Return (IRR) of the off-grid solar system, it can be concluded some of the following: IRR with energy prices of Rp.415, - (TDL. PLN) is smaller than the MARR, therefore, the project is stated as infeasible. However, the IRR with energy prices of Rp. 13294.46, - (price per unit of energy) is greater than the MARR, thus, it can be claimed that this project is worth to be done.

Optimalisasi Pemakain Daya Tersambung (KVA) Pada RSUD Dr. Abdul Aziz Singkawang
Get PDFAbstract– RSUD Dr. Abdul Aziz Singkawang selalu ingin meningkatkan diri baik dari segi fisik maupun sarana medis agar dapat memberikan pelayanan yang terbaik pada masyarakat. Hal ini tentunya disertai dengan meningkatnya kebutuhan akan energi listrik. Oleh karena itu untuk mengoptimalkan dan mengefisiensikan penggunaan daya listrik tersambung diperlukan manajemen energi listrik. Optimalisasi pemakaian daya tersambung dilakukan melalui konservasi energi pada sistem tata cahaya dan sistem tata udara, yaitu dengan mengganti peralatan yang tidak efisien dengan peralatan yang lebih efisien seperti lampu LED dan AC Inverter serta memperbaiki faktor daya beban listrik menggunakan bank kapasitor. Dari hasil perhitungan didapat penggunaan lampu LED dapat menurunkan konsumsi energi listrik sebesar 86.641,1 kwh per tahun, atau setara dengan penghematan biaya sebesar Rp.77.976.99077.976.990 per tahun. Penggunaan AC Inverter dapat mengurangi penggunaan energi listrik AC sebesar 527.242,7 kwh per tahun atau setara dengan penghematan biaya sebesar Rp.476.218.250476.218.250 per tahun. Penggunakan bank kapasitor dapat memperbaiki faktor daya hingga 0,99 dan menghemat penggunaan daya tersambung sebesar 44,2015 kva (22,44%), atau 43,7595 kw sebagai daya aktif yang setara dengan penghematan biaya sebesar Rp. 271.399.919271.399.919,8. /tahun. Berdasarkan perbandingan antara besarnya biaya investasi dan biaya yang dihemat dari optimalisasi beban, cara optimalisasi ini layak untuk dilaksanakan.

Identifikasi Dampak Gangguan Harmonisa dan Ketidak Seimbangan Magnitude Tegangan Serta Sudut Phasa Pada Performa Motor Induksi
Get PDFAbstract– The quality of supply system is found to be very effective in deteriorating the performance of three phase induction motors, a class of electrical machines which is widely used in industrial power systems. This paper presents an attempt to identify the impacts of harmonics and unbalance on induction motor performance. The presence of voltage magnitude and/or phase angle unbalance in the supply system is considered as well as harmonics distortion. Computer simulations of a VFD fed induction motor under different quality conditions of supply system are implemented using Powersim (PSIM). Six scenarios of harmonics contained supply system are tested, i.e. scenario 1 : balanced voltage magnitude, balanced phase angle and balanced transformer; scenario 2 : balanced voltage magnitude, balanced phase angle and unbalanced transformer; scenario 3 : unbalanced voltage magnitude, balanced phase angle and balanced transformer; scenario 4 : unbalanced voltage magnitude, balanced phase angle and unbalanced transformer; scenario 5 : balanced voltage magnitude, unbalanced phase angle and balanced transformer, and scenario 6 : balanced voltage magnitude, unbalanced phase angle and unbalanced transformer. The test results indicate that the quality of supply system has significant impacts on the speed and mechanical torque of three phase induction motor operating with harmonics contained and unbalanced supply system. Keywords– harmonics, unbalance, voltage magnitude, phase angle, induction motor
Realisasi Pengering Ikan Menggunakan Energi Biomass dan Panel Surya
Get PDFAbstract– Proses pengeringan ikan di daerah keluarahan Sungai Pinyuh masih dilakukan secara tradisonal, yaitu dijemur di bawah sinar matahari. Proses ini memakan waktu yang cukup lama, dibutuhkan waktu dalam pengeringan ikan 2 sampai 4 hari dan itu pun tergantung adanya sinar matahari. Selain itu kualitas hasil pengeringan tradisional masih kurang baik. Alat pengering ikan yang dirancang memanfaatkan panas yang bersumber dari pembakaran biomass dan panel surya yang berfungsi sebagai kolektor panas. Sehingga proses pengeringan dapat berlangsung cepat, setiap saat dan tanpa tergantung sinar matahari. Pengendalian suhu pengeringan dilakukan dengan cara buka tutup saluran udara pada alat pengering. alat pengering ini terdiri dari kolektor surya, tungku pembakaran biomass, ruang pengering (box) dan blower. Ruang pengering berfungsi sebagai tempat diletakkan ikan-ikan yang akan dikeringkan. Blower berfungsi mengalirkan panas yang bersumber dari kolektor surya atau pembakaran bimomass ke ruang pengering. Hasil pengujian menunjukkan dalam waktu dua jam, proses pengeringan terhadap 1 Kg ikan basah turun menjadi 500 gr. hasil ini menunjukkan bahwa proses pengeringan dengan menggunakan alat pengering tenaga biomass dan surya lebih cepat dibandingkan proses pengeringan secara manual selama 4 hari. Kualitas ikan hasil pengeringan mesin lebih baik dibandingkan dengan pengeringan secara tradisional. Keywords– alat pengering, biomass , panel sury
