“…Jumlah batubara yang masuk ke pulverizer berubah-ubah sesuai dengan beban unit pembangkit [2]. Oleh karena itu, outputcoal feeder pun berubah-ubah sesuai kebutuhannya.Pengaturan output coal feederdapat dilakukan dengan dua cara yaitu dengan motor penggerak yang putarannya dapat diatur (variable speedmotor) atau dengan motor putaran tetap yang dilengkapi dengan variable speed drive [3].…”

PT. ABZ is one of the big companies that runs its main business in the field of power generation in Indonesia. The company is experiencing problems in one of its equipment, namely coal feeder units 1-4 which often occurs coal plugging or coal blockage. Coal feeder is one of the main equipment that serves to regulate the amount of coal entering the pulverizer. This study aims to determine the root cause of problems from coal plugging or coal obstruction in coal feeder equipment at PT. ABZ using the FTA (Fault Tree Analysis) Method and provides a proposed improvement with the 5W + 1 H Method (what, why, who, when, where and how). Based on the analysis using FTA, it was found that the cause of coal plugging or blockage that occurs in coal feeder machines is due to contamination of the coal used, low calorific value of coal, the machine operates continuously, the machine is old, lack of control from the workers and coal wet when you want to use. Proposed improvements have been made and one of them is by separating wet coal from dry coal automatically using a coal online analyzer. Keyword : Coal Plugging, Coal Feeder, Fault Tree Analysis PT. ABZ merupakan salah satu perusahaan besar yang menjalankan bisnis utamanya dibidang pembangkit tenaga listrik di Indonesia. Perusahaan ini mengalami permasalahan di salah satu peralatannya yaitu coal feeder unit 1-4 yang sering terjadi coal plugging atau penyumbatan batubara. Coal feeder merupakan salah satu peralatan utama yang berfungsi untuk mengatur jumlah batubara yang masuk ke pulverizer. Penelitian ini bertujuan untuk mengetahui akar penyebab masalah dari gangguan coal plugging atau peyumbatan batubara di peralatan coal feeder di PT. ABZ dengan menggunakan Metode FTA (Fault Tree Analysis) dan memberikan usulan perbaikan dengan Metode 5W + 1 H (what, why, who, when, where dan how). Berdasarkan analisa menggunakan FTA, didapatkan bahwa penyebab coal plugging atau penyumbatan yang terjadi pada mesin coal feeder adalah dikarenakan adanya kontaminasi pada batubara yang digunakan, nilai kalori batubara yang rendah, mesin beroperasi secara terus menerus, mesin sudah tua, kurangnya kontrol dari pihak pekerja dan batubara basah saat akan digunakan. Usulan perbaikan telah dibuat dan salah satunya adalah dengan cara memisahkan batubara basah dengan batubara yang kering secara otomatis menggunakan alat coal online analyzer.

Indonesia is a tropical country which become one of the largest producer country of biomass especially from agricultural and forestry sector. One of the biomass source that has not been widely utilized is sago. Sago is an alternative source of carbohydrates besides rice, especially in the eastern region such as Papua. The potential of sago in Papua was 66,593 tons in 2018. This potential produces sago waste from processing sago starch, which can pollute the environment. Utilization of sago waste in the form of sago production waste as a source of biomass for electricity generation is an alternative solution. The result shows that sago pulp can be processed into briquettes with the calorific value of 6,327.4 kcal/kg – 6,946.7 kcal/kg. Sago production waste generated from the processing of sago starch is 14% so that the daily waste potential is 25.54 tons/day. Based on this potential, OWRS technology using pyrolysis-gasification obtained 6.6 tons/day of sago charcoal briquettes. The potential of heat energy was 42.03 Gcal/day. The potential of electricity that can be produced with updraft-fixed bed gasification from sago charcoal briquettes was 5.18 MWh. The theoretical power is 2.03 MW with an output power of 215.83 kW at 11% efficiency.
