This paper presents a modeling and analysis of the levelized cost of electricity (LCoE) related to solar Photovoltaic (PV) power plants. As the PV matures, the economic feasibility of PV projects is increasingly being evaluated using the LCoE. Regulation of the Minister of Energy and Mineral Resources of the Republic of Indonesia Number 19 the Year 2016 concerning the purchase of electricity from PV Power Plants by PT PLN (Persero) for On-Grid PV in East Nusa Tenggara with a purchase of 0.23 US$ / kWh, but the purchase price of electricity for Off-Grid PV system have not been determined. The aim of this study was to analyze LCoE for PV systems so that could help policymakers and PV investors to calculate the cost of providing PV systems for rural areas, especially in Kupang Regency. The research method uses an LCoE modeling approach. The results showed that LCoE PV On-Grid system at the level of 0.19-0.21 US$/kWh, and LPoE at the level of 0.21-0.23 US$/kWh. LCoE Off-Grid PV system at the level of 0.29-0.31 US$/kWh, and LPoE at the level of 0.31-0.33 US$/kW. The result from modeling PV On-Grid System, estimated by 2030, LPoE at the maximum level of 0.24 US$/kWh.

Perkembangan makro baik nasional pada umumnya dan Nusa Tenggara Timur (NTT) khususnya telah memperlihatkan adanya perubahan ke arah yang makin baik dalam berbagai bidang. Namun demikian, pembangunan daerah ini masih membutuhkan kerja keras dari berbagai kalangan terutama Usaha Mikro Kecil Menengah (UMKM) dalam menghadapi persaingan bebas dan lebih khusus menghadapi Masyarakat Ekonomi ASEAN yang sudah mulai berlaku di tahun 2016. Program Pengembangan Produk Unggulan Daerah (PPPUD) ini bertujuan untuk meningkatkan hasil produksi dengan mempercepat proses pengerjaan produksi UMKM usaha mebeler berbasis teknologi tepat guna yang lebih modern. Mitra program PPPUD ini adalah UD. Gusti Karya yang merupakan salah satu pelaku UMKM di Kota Kupang. Menurut mitra, kerajinan mebeler saat ini sangat digemari oleh masyarakat kota kupang, sebab selain kuat, mebel dapat dibuat sesuai selera konsumen. Adapun cara peningkatan produksi yang diterapkan pada kegiatan ini adalah melakukan peremajaan peralatan teknologi tepat guna dengan sistem yang lebih modern dibandingkan dengan peralatan yang mereka miliki saat ini. Luaran yang diharapkan dari program ini adalah peningkatan produksi sehingga dapat meningkatkan penghasilan dari mitra. Berdasarkan hasil pendampingan dan monitoring yang dilakukan setelah kegiatan ini diketahui bahwa, dengan adanya penerapan teknologi tepat guna tersebut dapat meningkatkan kinerja produksi mitra sampai 40 persen lebih cepat dari yang sebelumnya.

The macroeconomic growth in East Nusa Tenggara (NTT) has shown changes for the better in var-ious fi elds. This improving economic growth has also had a positive impact on the retail business sector. This is indicated by the increasing interest of the people of Kupang city towards wooden furniture. However, the increasing public interest in furniture is a challenge for furniture entrepreneurs to be able to meet these needs. UD. Gusti Karya is a micro business unit that produces furniture in the city of Kupang. UD. Gusti Karya has started its activities since 1997, but until now the turnover generated has continued to decline due to the limited functionality of the furniture machines used. This activity is part of the PPPUD Program in partnership with UD. Gusti Karya. This activity aims to provide solutions to problems that are being faced by UD. Gusti Karya, which is a micro business unit that produces furniture in the city of Kupang. The solution given is related to productivity problems, by providing assistance and the application of more modern multi-functional furniture machines. Because according to partners, so far, they still use manual equipment more, so it is necessary to implement machines that have more modern technology than those currently available. The output that was achieved from the implementation of this program was an increase in productivity which resulted in an increase in partner turnover by 78.9% from the previous one.

Bolok Steam Power Plant has its own 6.3 kV usage network to service loads such as Feed Water Pump and Circulating Pump Feed. This self-use network is expected to supply unit loads at the Bolok coal-fired steam power plant without any interference. The presence of disturbances such as short circuit in the electric power system can cause problems such as damage to electrical equipment and the emergence of a power outage. Therefore problems that arise like this require an analytical study to determine the short circuit current that will occur while reducing the consequences that arise. This study aims to determine the largest short circuit fault current with the help of ETAP 12.6.0 software. Short circuit simulation results with ETAP 12.6.0 will be compared with manual calculations based on positive, negative and zero sequence impedance values from the point of disturbance location. Based on the results of the research that has been done, it is known that the type of two-phase short circuit interference to the ground is the largest type of interference, which is equal to 10,615 kA on the generator bus. Whereas for the smallest type of short circuit interference is the type of disturbance one phase to the ground that is equal to 3,967 kA on the OutGoing II bus. From the results of the simulations conducted, it can also be seen that changes in the value of short circuit fault currents are affected by changes in the number of operating loads. The more load that operates the positive and negative sequence impedance the smaller and the value of the short circuit current will be greater, while the zero sequence impedance does not affect the amount of load operating, as well as the opposite.

ABSTRACT The research aims to determine the size of the OCR Motor Pump, Grading Time OCR Motor Pump, coordination Motor Pump OCR and auxiliary OCR on PLTU SMS Energy in the Bolok industrial area.  Research started by collecting electricity data PLTU SMS Energy in the form of secondary data. These data are used to create single line diagrams, simulations and analysis using ETAP 12.6.0. The results of the research get an  OCR Setting with the following short-circuiting value parameters.  Setting relay Bus 1 FCP with Ip = 3 A and TMS = 0.1 s, setting relay Auxiliary bus I with IP = 2 A and TMS = 0.21 s, setting relay bus OutGoing 1 with IP = 0.6666 A and TMS = 0.30 s and setting relay bus G1 with IP = 1 A and TMS = 0.45 S. TMS OCR on Pump motor is plotted faster due to the most downstream OCR location with smaller short-circuited tension. From the coordinating curve of Grading Time obtained that has been in accordance with IEEE Standard 242-namely  0.2 – 0.4 seconds.  Keywords: Over Current Relay, OCR Coordination, Grading time, OCR setting, ETAP 12.6.0   ABSTRAK Penelitian ini bertujuan untuk mengetahui besaran settingan OCR Motor Pump, Grading Time OCR Motor Pump, koordinasi OCR Motor Pump dan OCR auxiliary pada PLTU SMS Energi di kawasan industri Bolok.  Penelitian diawali dengan mengumpulkan data kelistrikan PLTU SMS Energy berupa data sekunder.
