Abstract

Pabrik Kelapa Sawit Sungai Rungau Mill mempunyai bahan bakar biomassa yang sangat melimpah. Akan tetapi penggunaan sumber bahan bakar ini harus dioptimalkan agar performa pabrik dapat berjalan dengan baik dengan cara mengkaji kebutuhan energi secara aktual. Jumlah dan komposisi bahan bakar yang digunakan harus diperhatikan sesuai dengan kebutuhan. Kelebihan atau kekurangan bahan bakar dapat menyebabkan terjadinya penurunan tekanan dan komposisi yang tidak tepat yang akan menyebabkan perambatan panas yang kurang baik. Tujuan dari penelitian ini adalah mengkaji kebutuhan dan komposisi bahan bakar yang sesuai dengan energi yang dibutuhkan untuk proses produksi kelapa sawit. Pabrik Kelapa Sawit Sungai Rungau Mill mempunyai sistem pembangkit uap yang mengubah air menjadi steam untuk menggerakan turbin uap dengan bahan bakar serabut dan cangkang hasil dari proses produksi tandan buah segar. Metode yang digunakan dalam penelitian ini adalah pengukuran langsung di Pabrik Kelapa Sawit Sungai Rungau Mill dengan berbagai instrumen dan peralatan yang ada. Dari proses produksi tandan buah segar dengan kapasitas 82,3 ton/jam diperoleh serabut dan cangkang masing-masing sebanyak 11,36 ton/jam dan 4,73 ton/jam. Kemudian bahan bakar tersebut dipakai untuk boiler dengan jumlah serabut 10,60 ton sedangkan cangkang 2,73 ton dengan persentase 79,49 % serabut dan 20,51 % cangkang. Selanjutnya pembakaran dalam boiler menghasilkan steam dengan jumlah 43,2 ton/jam yang digunakan untuk menggerakan turbin sehingga menghasilkan daya listrik sebesar 1475 kWh.

Abstract

Indonesia is the largest producer of Crude Palm Oil (CPO) in the world. The use of CPO is mostly for edible oils and biofuels. Even though CPO potential is huge, the development of CPO in other forms is still limited. CPO has a melting point of 25˚C - 50˚C which is suitable to be develoved in the environment of Indonesia. This characteristic allows CPO to be used as phase change material. This study examines the use of CPO as a material to reduce the thermal conductivity of light bricks. The idea is to make the brick as a building material has the ability to maintain room conditions from fluctuative ambient temperatures. The results showed that the addition of effective CPO to reduce the thermal conductivity of light bricks was 2.5 to 7.5 ml per 160 cm3.

Abstract

Steam is a utility that have an essential function in palm oil production. Steam is mainly used in steam turbine to move the generator to produce electricity. Steam also has a lot of other functions such as heating cold oil in storage tank, heating coil in kernel drying, etc. Steam is produced in a machine called boiler. Boiler require a treated feed water as an input. To maintain boiler performance and lifetime, one need to control the TDS (Total Dissolved Solid) in boiler feed water in a range of 2100 2500 ppm. TDS is a parameter that shows the solid concentration which dissolved in the water. TDS has to be checked every hour to maintain its concentration controlled. In a practical use, TDS monitoring is a simple process but take a lot of time to proceed. Water from the sampling pipe collected in a bottle then cooled until room temperature. TDS from cooled boiler water then measured with a device called TDS meter. To control TDS value in the standard condition, the measurement time need to be reduced. Therefore, a faster method to measure TDS in boiler water is needed. An easier and faster measurement using a system which consisted of sensor, microcontroller, LCD display is one of the idea to reduce unneccessary measuring time. The development and experiment of this TDS monitoring device is situated in Nagasakti Palm Oil Mill, Riau Province, Indonesia.
