Abstract

Electricity is one of basic human needs. However, PLN's ability to meet customer demands is hampered by its limitations. On the other hand, the sunny geographical advantage of Makassar city can be utilized as a new renewable and environmentally friendly energy source in a smart home. Smart house is a family residence that is able to synergize electricity usage based on the habits of its residents with the help of smart technology so that comfort, safety and efficiency of using electrical energy are obtained. The utilization of solar cell hybrid power – battery – PLN can be implemented in addition to meeting the needs of electricity load in the smart home, it can also contribute excess energy to fulfill off-grid building load.  Monte Carlo Simulation (MCS) is carried out at the beginning of data processing by randomly generating 24-hour models of solar irradiance and smart home load requirements along with weather conditions. PLN not only takes over fulfilling the needs of the smart home load when there is less and or no sunlight and minimum battery capacity conditions, but also it will charge the battery capacity up to 100% every midnight. On average, the daily load requirement for a smart home is almost half the energy produced by PVs, which are 12,439 kW and 24,509 kW respectively. Furthermore, the smart home hybrid power is capable of producing 8,946 MW of excess energy in a year to serve the off-grid building load needs.

Abstract

Penggunaan daya listrik pada gedung Kantor Bupati Kabupaten Halmahera Barat semakin hari semakin bertambah sesuai dengan kebutuhan dan perkembangan Kabupaten Halmahera Barat di masa akan datang, otomatis penambahan daya sangat diperlukan. Untuk memperoleh daya listrik terpasang yang efisien, oleh karena itu perlu dilakukan observasi dan perhitungan daya yang digunakan sesuai dengan ilmu kelistrikan.Konsumen komersial atau perkantoran rata-rata memiliki standar faktor kebutuhan sebesar  70% - 90% dan faktor beban 25% - 30% untuk mendapatkan penggunaan daya listrik yang efisien. Faktor kebutuhan adalah perbandingan antara kebutuhan maksimum (beban puncak) terhadap total daya tersambung.Total penggunaan daya maksimum 197,4 kVA dengan standar faktor kebutuhan sebesar 1,88. Total luas ruangan ber-AC 9.361 m2, dengan mengkomsumsi energi listrik selama satu bulan totalnya 36.135 kWh/bulan, jika di bandingkan dengan standar IKE maka nilainya sangat efisien, berbeda dengan perhitungan IKE untuk ruangan tidak ber-AC yang memiliki total luas ruangan 875 m2 dan mengkomsumsi energi selama satu bulan 2,484 kWh/bulan, jika di bandingkan dengan standar IKE untuk ruangan tidak ber-AC maka nilai IKEnya masuk kriteria ruangan yang boros atau sangat boros mengkomsumsi energi listrik.Kata kunci: Daya listrik terpasang, factor beban, faktor kebutuhan, perbandingan intensitas  komsumsi energi (IKE).
