Abstract

Air conditioning is strongly influenced by Refrigerant. R.22 refrigerant is currently still widely used with high level of electric power consumption. The purpose of this research is to analyze the influence of types of refrigerant to the electric power consumption of AC by measuring the electric power requirement of each Refrigerant (R.22, R.410, R.32, EnggasM60 and Isceon MO99). The results showed that R.410 uses 335 Watt with the total cost of Rp 42,210 / month, R.32 uses 328 Watt power with the total cost of Rp 41.328 / month, R.22 uses 271 Watt power with theotal cost of Rp 34.146 / month, Huffin M60 uses 262 Watt power with the total cost of Rp 33.012 / month. While Isceon M099 requires 262 Watt with the total cost of Rp 33.012 / month at the temperature of 24,4 ° C.

Abstract

Beban sistem kelistrikan di Bali saat ini adalah 662 MW yang disuplai dari unitpembangkitan pada GI Pesanggaran, GI Pemaron, GI Gilimanuk dan unit kabel laut yangberasal dari Jawa. Rencana penambahan pasokan daya listrik untuk Provinsi Bali tahun 2013-2022 adalah pembangkitan Kabel Laut (2014), PLTU IPP (Independent Power Producer)Celukan Bawang (2015) dan jaringan Saluran Udara Tegangan Ekstra Tinggi (SUTET) 500 kV(2017). Analisis peramalan beban tahun 2013-2022 menggunakan metode regresi linear danmelakukan analisis kapasitas CB dengan menghitung arus hubung singkat menggunakanprogram ETAP. Berdasarkan hasil analisis diperoleh peramalan beban daya listrik pada sistemkelistrikan di Bali tahun 2022 adalah sebesar 1227.4 MW. Hasil analisis kapasitas CB sistemkelistrikan di Bali tahun 2013-2022 perlu dilakukan penambahan kapasitas CB pada GIGilimanuk (42.349kA), GI Kapal (40.701kA) dan GI Pesanggaran (43.918kA).

Abstract

Electromagnetic launchers are devices that use electromagnetic forces to launch high-speed projectiles, utilizing accelerated armature shifts along with a pair of conductive rails. Electromagnetic launchers have been studied as high-speed ballistic launchers for various applications such as military weapons to space launches. Based on the development of capacitor technology and the limited development of electromagnetic launchers, especially in the field of launching high-speed projectiles with capacitor supply as the development of electromagnetic weapons technology, research was carried out by making the design of electromagnetic launchers with capacitor supply to produce high-speed projectiles (more than 180m/s based on variations in rifle bullet speed) as the development of electromagnetic weapons technology. The results of the research on the design of electromagnetic launchers with capacitor supply obtained the final projectile velocity value of 200,644 m/s, which consists of three main components namely the rail system, the gas injector, and the supply system.
