Abstract

Teknologi informasi dan telekomunikasi merupakan teknologi yang pertumbuhannya sangat cepat. BTS merupakan jaringan yang dipakai untuk memenuhi kebutuhan telekomunikasi seluler. Salah satu yang harus diperhitungkan dalam membangun sebuah BTS adalah  link budget. Link budget merupakan sebuah cara untuk menghitung mengenai semua parameter dalam transmisi sinyal mulai dari gain dan loss dari transmitter (Tx) sampai receiver (Rx) melalui media transmisi. Penelitian ini dilakukan pada BTS Rooftop yang berlokasi di Cemara IV. Adapun parameter yang dianalisis dalam link budget pembangunan BTS ini antara lain Coverage, Fresnel Zone, Free Space Loss, Effective Isotropic Radiated Power dan Received Signal Level. Analisis link budget dilakukan untuk memastikan bahwa level daya penerimaan lebih besar atau sama dengan level threshold ( RSL ≥ Rth ). Setelah melakukan perhitungan seluruh parameter link budget maka diperoleh nilai RSL pada BTS pancing sebesar  -31,2602 dBm dengan sensitivitas daya RAU (Rth) pada antena microwave BTS tersebut sebesar -76 dBm sedangkan nilai RSL pada MS sebesar -90,9799 dBm dengan sensitivitas MS (Rth) sebesar -101 dBm sehingga BTS Cemara IV layak on air.

Abstract

Biogas from liquid waste from palm oil processing, palm oil mill effluent (POME), can be utilized in biogas power plants as a source of renewable energy (PLTBg). The PLTBg electrical system is equipped with a coordinated protection system. Then, the protection system must also maintain the continuity of electrical service in parts that are not affected by disturbances. Coordination of the protection system is essential. In this research, the electrical transient analysis program (ETAP) carries out the short circuit current analysis, and the coordination of overcurrent protection is constructed from its inverse-definite minimum time characteristics. The analyzed data contributed to selecting the right protection devices. A combination of overcurrent protection, directional protection, and frequency protection change rate supported a reliable electrical power system for a biogas power generation plant as distributed generation. The result shows that modern microprocessor-based protection relays support several protection features in one device and can be integrated into a supervisory control and data acquisition (SCADA)-controlled protection system to enhance their capabilities.
