Biodiesel Production from POME (Palm Oil Mill Effluent) and Effects on Diesel Engine Perfor-mance

Abstract

one way to reduce the scarcity of fuel oil is to make environmentally friendly alternative fuels such as biodiesel. The utilization of biodiesel can be a new energy source and also help reduce the excessive use of fuel, especially diesel and diesel oil in Indonesia. In Indonesia, the amount of palm oil will reach 49.7 tons by 2021, and this data is up 2.9% from the previous year. Palm fruit is processed into CPO. More palm oil processing will produce waste called POME (Palm Oil Mill Effluent). The diesel engine transesterification method is suitable for the manufacture of biodiesel. The amount of base on the catalyst's surface affects the catalyst's activity. So that the higher the base value on the catalyst, the higher the yield of biodiesel that will be produced. The biodiesel produced will be tested on a 4-stroke diesel engine with a B5 and B10 blending composition. The study's results showed that the density and viscosity values for B5 were 5.8 cSt and 810 Kg/m3 and for B10 were 6.3 cSt and 860 Kg/m3. As for engine performance, power, torque, and SFC for B5 fuel at 4000-watt load conditions and 1000 Rpm, engine speeds are 1.18 Kw, 11.28 Nm, and 256.8 gr/Kw. B10 at 4000-watt load condition and 1000 Rpm engine speed is 1.16 Kw, 11.12 Nm, and 269.2 gr/Kw.

Perencanaan Distribusi Penerangan Kapal Ikan Multipurpose 70 GT Menggunakan Metode Zonal Cavity

“…Dalam penentuan mesin utama dan generator harus benar-benar akurat karena hal ini terkait dengan biaya operasional kapal khususnya konsumsi bahan bakar. Semakin besar daya dan torsi suatu mesin maka akan berdampak pada konsumsi bahan bakar juka akan semakin besar [4][5] [6], sehingga perlu dilakukan perencanaan yang matang seperti perencanaan distribusi penerangan yang hemat energi agar mesin (generator) yang digunakan tidak terlalu boros [7] [8]. Dalam merencanakan instalasi dan distribusi penerangan di atas kapal harus mengikuti standar dari regulasi yang mengatur tentang intensitas tingkat pencahayaan ruangan di atas kapal.…”

Effect of Temperature Variations of Corn (Maize) Oil Biodiesel on Torque Values and Thermal Efficiency of Diesel Engines

“…Studies of the potential of algae [7] and the potential of animal oil to become biodiesel indicate that animal oil with a mixture of up to B60 can provide a good thermal efficiency value for the engine as well as a low emission value compared to fossil fuels [8]. Biodiesel production from pome (palm oil milf effluent) results good engine performance values compared to diesel fuel [9]. The research that uses corn oil (maize) also gives good performance values for diesel engines [10].…”

Testing the Inclination of an Industrial Diesel Engine Under Static Conditions According to the International Convention for the Safety of Life at Sea (SOLAS) Regulations

“…email: amaliaikaw@lecturer.itk.ac.id Wira Setiawan is with Department of Naval Architecture, Kalimantan Institute of Technology, Balikpapan, 76127, Indonesia. e-mail : wira@lecturer.itk.ac.id Diesel engines have good performance if the power and torque produced are large, as well as the thermal efficiency values must also be high (between 30% Thermal Efficiency (ηth) to 50%) and low Specific Fuel Consumption (SFC) values [7] [8]. Because ship engines operate longer than industrial engines and the working environment of ship engines is different from the work environment of industrial engines, there must be special requirements met by diesel engines before they are said to be suitable for use on ships.…”

“…Due to the unstable working environment of the ship's engine due to the influence of waves, it is feared that the resulting engine performance value will also not be good, if usually engine performance testing is limited to fuel variations such as the effect of modifying the timing of natural gas injection on engine performance [12], a combination of biodiesel from microalgal [13], variations of biodiesel fuel from animal oils [14], determination of engine performance values with biodiesel from palm oil mill effluent (POME) [8] and calculation of performance values using corn oil [7]. All of these research was carried out under normal engine conditions (not in tilted conditions) or in the sense that they were only to test engine performance, for offshore.…”
