Electricity is very important for the growth and economy of a country. Biomass wastes such as waste from oil palm plantation companies can be harnessed for this purpose since they are usually abundant in nature. The aim of this study is to evaluate the utilization of empty palm fruit bunch for the generation of electricity. The empty fruit bunch (EFB) was used in firing a steam turbine plant (boiler) for the generation of electricity. The power plant that was used in this research is owned by PRESCO Nigeria Limited located in Ikpoba-Okha local government area of Edo state. 1.7 MW of electricity was generated by burning empty fruit bunch (EFB) at a rate of 896 kg/h when the steam boiler was used. This value was compared with the traditional power plant fired using methane gas which produces 4.5MW. This value (1.7 MW) shows that EFB is a very good alternative for firing a boiler plant, power generation and elimination of wastes.

Natural gas is a source of energy that comes from the earth which is depleting every day, an alternative source of energy is needed and one of the sources comes from biogas. There is an abundance of empty fruit bunch (EFB) that comes from palm oil plantation that can become a substrate for biogas production. A methodology of fermentation based on Verein Deutscher Ingenieure was used to utilize EFB as a substrate to produce biogas using biogas sludge and wastewater sludge as inoculum in wet fermentation process under mesophilic condition. Another optimization was done by adding a different water ratio to the inoculum mixture. In 20 days, an average of 6gr from 150gr of total EFB used in each sample was consumed by the microbes. The best result from 20 days of experiment with both biogas sludge and wastewater sludge as inoculum were the one added with 150gr of water that produced 2910ml and 2185ml of gas respectively. The highest CH 4 produced achieved from biogas sludge and wastewater sludge with an addition of 150gr of water to the inoculum were 27% and 22% CH 4 respectively. This shows that biogas sludge is better in term of volume of gas that is produced and CH percentage.

Pada umumnya petani jamur dalam melakukan proses sterilisasi masih menggunakan alat sederhana berupa bejana dari drum bekas yang dipanaskan dengan tungku/gas elpiji, sehingga suhu tidak tercapai (< 100 oC), waktu pemanasan terlalu lama (6-8 jam) dan lebih 30% terkontaminasi oleh jamur liar. Tujuan dari modifikasi alat ini adalah mengetahui suhu dan tekanan yang optimal pada proses sterilisasi media tumbuh jamur (Baglog), sehingga  kontaminasi jamur liar dapat berkurang, kapasitas produksi dapat ditingkatkan dan waktu sterilisasi baglog dapat dipersingkat. Metode yang digunakan  adalah pertama melakukan desain gambar alat, kemudian pembuatan alat, uji coba dan unjuk kerja alat. Modifikasi Alat, terdiri dari 2 (dua) Unit yaitu Boiler dan Sterilisator. Boiler adalah bejana tertutup dimana panas pembakaran dialirkan ke air sampai terbentuk air panas atau steam, kemudian digunakan untuk mengalirkan panas ke suatu proses. Unit  boiler yang digunakan tipe  Water Tube Boiler, tipe ini  air umpan boiler  mengalir melalui pipa–pipa masuk ke dalam bejana. Air yang tersikulasi dipanaskan oleh gas pembakar membentuk steam pada daerah uap dalam bejana. Unit  boiler terbuat dari  plat baja tebal 3,5 mm, tinggi 125 cm dan diameter 57 cm, dilengkapi dengantermometer,presure gauge,savety valve,kran pengalir uap panas. Bagian dalam bawah terdapat pipa pemanas air dari pipa schedule 1 inch, yang dipasang horizontal 20 buah. Di bagian samping dipasang pipa kaca tebal 5 mm untuk memantau level air. Kaki dari besi baja Kanal U/ UNP  tinggi 30 cm. Sterilisator atau autoklaf ; alat pemanas tertutup untuk mensterilisasi suatu benda menggunakan uap bersuhu dan bertekanan tinggi (1210C, 15 lbf/in2) selama kurang lebih 15 menit. Suhu yang tinggi inilah yang akan membunuh microorganisme. Unit sterilisator dari plat stainless steel tebal 2 mm, tinggi 150 cm dan diameter 120 cm. Bagian dalam diberi plat stainless steel vorporasi tebal 1,3 mm dan rak dorong dari kawat stainless steel setinggi 27 cm. Bagian atas dipasang   termometer. Kaki dari baja siku  setinggi  50 cm. Hasil uji coba unjuk kerja alat diperoleh  kapasitas stelisator 350-500 baglog, suhu  berkisar 100-120 0C tekanan 1,5-1,9 bar, waktu tercapainya suhu pada alat 2-3 jam.

Electricity Costs

In the animal feed industry, steam is used in pellet making machines. In this process, steam from the boiler is distributed to the pellet mill through the pipe. The purpose of this study is to observe the waste of electricity costs of operating a boiler by calculating heat loss in a distribution pipe. The method of assessing heat loss is done by calculating losses caused by heat loss in the boiler distribution. Then make a calculation application model based on the data obtained. From the data analyzed, the amount of heat lost in the non-insulating distribution pipe is 0.766 kJ/s with a loss of Rp 5.628,600 operating costs per month compared to heat loss in an isolated pipe condition of 0.047 kJ/s with losses which cost slightly more than Rp 368 190 / month. This heat loss calculation process is made on an android application by entering the calculation formula on the program and the data that has been obtained.
