Abstract

PG Kebon Agung berdiri tahun 1905 dan pada saat ini kapasitas giling 6.000 tth. Boiler merupakan mesin yang paling vital dalam pabrik gula, karena selain digunakan sebagai sumber energi pemanas untuk memasak gula di bagian proses juga digunakan sebagai pembangkit listrik. Sumber energi untuk proses produksi gula dihasilkan dari ketel uap dalam bentuk uap panas (steam). Kebutuhan uap di PG Kebon Agung disuplai menggunakan 3 buah boiler dengan merk Yoshimine dan Jiangxy liang lian (JJ) dengan kapasitas 80 ton/jam. Bahan bakar yang digunakan oleh boiler yaitu Baggase atau sekam padi. Seiring dengan bertambah banyak akan konsumsi gula maka PG. Kebon Agung di tuntut untuk menjaga perfomansi mesin-mesin produksinya. Karena jika mesin-mesin pada industri gula tersebut digunakan secara terus menerus, maka akan mempengaruhi keandalan atau (performa) dan umur pakainya. Hal ini akan berpengaruh langsung terhadap efisiensi produksi. Oleh karena itu perlu dilakukan analisa terhadap siklus rankine apakah masih dalam batasan kondisi yang andal atau tidak. Metodologi yang digunkakan dalam penelitian ini melakukan perhitungan siklus rankine sistem pembangkit uap pada PG. Kebon Agung Malang. Untuk mengetahui efisiensi siklus rankine, hate rate, efisiensi boiler dapat dilakukan analisis termodinamika menggunakan data operasional pada berbagai komponen seperti boiler, turbin, dan pompa. Penelitian ini diharapkan dapat mengetahui kinerja masing-masing komponen, efisiensi siklus rankine, hate rate serta efisiensi pada boiler. Berdasarkan hasil analisis thermodinamika di dapat Total daya yang dihasilkan turbin adalah sebesar 11389.79 kW, daya total yang dihasilkan pompa adalah 128,22 kW, kalor yang dihasilkan boiler sebesar 224788,87 kW kW, Kalor yang diperlukan untuk proses sebesar 40439,85 kW. didapatkan heat rate sebesar 21693,35 kJ/kWh. Didapatkan efisiensi siklus sebesar 23 % menandakan plant di PG. Kebon Agung berjalan dengan baik. Hasil perhitungan Direct Method efisiensi boiler diperoleh Efisiensi boiler yoshimine 1 sebesar 71,20 %, yoshimine 2 sebesar 71, 52 % dan Jian Lian Liax sebesar 71,10 % sehingga rata-rata efisiensi boiler yaitu 71%. Efisiensi isentropic turbin diperoleh efisiensi sebesar Turbin St.Gilingan 64%, St. Power Plant 64%, Turbin IDF FDF FW 62%

PG Kebon Agung was founded in 1905 and at this time the milling capacity is 6,000 tth. Boilers are the most vital machines in sugar factories, because in addition to being used as a source of heating energy to cook sugar in the process section, it is also used as a power plant. The energy source for the sugar production process is produced from the steam boiler in the form of hot steam (steam). Steam needs in PG Kebon Agung are supplied using 3 boilers with the yoshimine and Jiangxy liang lian (JJ) brands with a capacity of 80 tons / hour. The fuel used by the boiler is Baggase or rice husks. As the consumption of sugar increases, PG. Kebon Agung is required to maintain the perfomancy of its production machines. Because if the machines in the sugar industry are used continuously, it will affect their reliability or (performance) and service life. This will have a direct effect on production efficiency. Therefore, it is necessary to analyze the rankine cycle whether it is still within the limits of reliable conditions or not. The methodology used in this study calculated the rankine cycle of the steam generation system on PG. Kebon Agung Malang. To determine the efficiency of the rankine cycle, hate rate, boiler efficiency can be carried out thermodynamic analysis using operational data on various components such as boilers, turbines, and pumps. This research is expected to be able to determine the performance of each component, rankine cycle efficiency, hate rate and efficiency in boilers. Based on the results of thermodynamic analysis in can The total power produced by the turbine is 11389.79 kW, the total power generated by the pump is 128,22 kW, the heat produced by the boiler is 224788,87 kW, the heat required for the process is 40793.28 kW. obtained a heat rate of 21693,35 kJ/kWh. Obtained cycle efficiency of 23% indicates a plant in PG. Kebon Agung went well The results of the Direct Method calculation of boiler efficiency obtained yoshimine 1 boiler efficiency of 71.20%, yoshimine 2 of 71.52% and Jian Lian Liax of 71.10% so that the average boiler efficiency is 71%. The efficiency of the isentropic turbine is obtained by the efficiency of the St. Mill Turbine 64%, St. Power Plant 64%, IDF FDF FW Turbine 62%
