Abstract

Pabrik kelapa sawit (PKS) adalah fasilitas produksi yang memproses tandan buah kelapa sawit menjadi crude palm oil (CPO), yang merupakan minyak mentah kelapa sawit. Proses pengolahan tandan buah kelapa sawit menjadi CPO membutuhkan sejumlah besar energi untuk menggerakkan mesin dan peralatan di berbagai stasiun di dalam pabrik kelapa sawit. Energi yang digunakan dalam PKS berasal dari dua sumber utama, yaitu boiler dan generator set (genset). Uap, yang dihasilkan oleh boiler, digunakan sebagai penggerak turbin untuk menghasilkan energi listrik di dalam pabrik kelapa sawit. Namun, salah satu tantangan yang dihadapi dalam penggunaan energi potensial uap ini adalah sifatnya yang rentan kehilangan panas. Banyak upaya telah dilakukan untuk mengurangi kehilangan energi panas, seperti mengisolasi saluran pipa uap, menganalisis isolasi pipa uap untuk mengurangi kerugian panas, serta memeriksa kerusakan isolasi uap yang dapat menyebabkan kerugian energi panas. Oleh karena itu, penelitian ini dilakukan untuk mengevaluasi kerugian energi panas akibat konveksi pada pipa saluran uap dari turbin menuju BPV (back pressure vessel) di PKS. Penelitian ini berjudul " Analisa Kehilangan Panas Secara Konveksi Pada Saluran Steam (Pipa) Dari Turbin Ke BPV (Back Pressure Vessel) Pada PKS (Pabrik Kelapa Sawit) Kapasitas 45 Ton/Jam Studi Kasus Turangie Palm Oil Mill PT. PP. London Sumatra Indonesia, Tbk."

Abstract

Efisiensi turbin merupakan sebuah parameter dari derajat keberhasilan system turbin untuk mendekati proses ideal dengan satuan persen (%). Efisiensi turbin diketahui dengan membandingkan kerja ideal turbin dengan kerja aktual turbin. Laju massa uap adalah jumlah uap yang mengalir ke turbin uap dalam satuan waktu. Penelitian ini bertujuan untuk mengetahui pengaruh laju massa uap terhadap  nilai efisiensi turbin uap. Penelitian dilaksanakan pada 3 oktober-16 oktober 2023 di pabrik kelapa sawit kapasitas 50 ton/jam. Adapun metode yang digunakan dalam penelitian ini yaitu menggunakan metode Deskriptif Kuantitatif berdasarkan data primer pada turbin uap. Rata-rata laju massa uap yang terjadi pada 3 oktober-16 oktober 2023 yaitu 6,70 kg/s atau 24,12 ton/jam. Sedangkan rata-rata efisiensi kerja turbin uap pada periode yang sama 32,69 %. Nilai efisiensi kerja turbin uap tertinggi yang tercapai pada 3 oktober-16 oktober 2023 di pabrik kelapa sawit Kapasitas 50 Ton/Jam yaitu 37,365% dengan laju massa uap 6,38 kg/s. Dari penelitian ini dapat diketahui bahwasanya laju massa uap berpengaruh signifikan terhadap efisiensi kerja turbin uap, dapat dilihat dari koefisien persamaan regresi yang negatif, yang berarti semakin besar laju massa uap, nilai efisiensi turbin uap juga akan menurun, begitu pula sebaliknya.

Abstract

The productivity of rubber plantations is determined by the type of clone, the age of the plant, the level of land suitability, and the exploitation system applied. The exploitation system applied determines the productivity of the rubber plantation because it is related to the use of the skin and the physiological process of latex. Implementing the right exploitation system can ensure high and sustainable productivity. On the other hand, the implementation of the wrong exploitation system can result in low productivity and shorten the economic life of the plant. This study aims to determine the productivity of rubber plants in clone PB 260 with various tapping systems. This research was conducted at Afdeling I Kebun Bangun PT. Perkebunan Nusantara III using a descriptive analysis method by collecting secondary data on the productivity of the PB 260 clone rubber plant from 2016 – 2020. The parameters observed were the production data of the PB 260 clone rubber plant with various tapping systems. The results of this study indicate that the analysis of rubber plant productivity data in 2016 – 2020 had the highest production in 2017 with a planting year of 2009 and the lowest in 2020 with a planting year of 2000. Meanwhile, overall, the highest production was in 2018 and the lowest was in 2016. The factors that influence the high and low productivity are caused by the tapping system that is not permanent or changing, the lack of application of fertilization, the reduction in the number of trees in the field caused by being attacked by JAP (White Root Fungus), KAS (Dry Alur Sadap), Moldy Road, fallen trees due to strong winds, and the age of the plants. The relationship between production and cost of goods/kg is that the greater the production obtained, the lower the cost of goods/kg.

Abstract

The smoke chamber used has a capacity of 3,420 kg with a rubber sheet smoking period of five days. Reducing the water content (moisture content) on the rubber sheet is used by heating it with a smoking system. For smoke chamber operations, the fumigation temperature used on the first day is 40 - 45°C, on the second day 45 - 50°C, on the third day 50 - 55°C, on the fourth day 55 - 60°C, and on the fifth day the smoking temperature was maintained at 60°C. FDF and IDF are two air distribution devices, where the FDF functions to blow the air into the smoke chamber and the IDF draws the air into the smoke chamber. The balance between exhaled air and that drawn out of the smoke chamber must be proportional. Too much airflow will collect in the smoke chamber and too much the air withdrawal will affect heat transfer. After installing the FDF and IDF tools, the smoking time is 4 (four) days, so the use of smoked wood (rubber stem wood) is reduced from 3.19 m3 (for 5 days of smoking) to 2.55 m3 (for 4 days of smoking). There is a saving of one operational day. Reducing the use of smoked wood has an impact on processing efficiency. Heat energy from smoking has also increased. Before the installation of the FDF and IDF devices, the amount of heat energy was 64,074 kcal/day (320,372 kcal in 5 days). After installing the FDF and IDF devices, they increase the amount of air / oxygen (O2) in the combustion process so that there is an additional heat energy of 9,461 kcal/day (47,305 kcal in 5 days). The total amount of heat energy produced is 367,677 kcal for 5 (five) days of smoking. FDF and IDF are two air blowers commonly known as blowers with their respective specifications: The FDF used has an electric power of 3 kilowatts (4 horsepower/hp) with a rotation of 1,420 rpm, while the IDF has an electric power of 7.5 kilowatts (10 horsepower/hp). hp) at 1,440 rpm.

Abstract

Oil palm is a plantation crop that has an important role in Indonesia today. This plant is a plant that produces vegetable oil and its derivative products. The processing of oil palm empty bunches into particle board as a strategy for utilizing solid waste from oil palm processing has been carried out. The test was carried out to determine the hardness, weight and moisture content to produce particle board. The board making was carried out in April - August 2020. The location was at the Laboratory of Soil and Fertilizer at the College of Agricultural Agribusiness and Plantation (STIPAP) and the Laboratory of Industrial Chemistry Polytechnic Medan (PTKI). The results showed that the largest water content of oil palm empty fruit bunches was obtained by 44%, then for the weight of the content obtained 1.131 gr / cm3 with a ratio of 50% oil palm empty bunches fiber and 50% resin adhesive and a hardness test value of 76 kg. . The moisture content can affect the resistance and weight of the particle board so that drying is necessary. Meanwhile, the weight of the contents has an effect on particle density, thereby increasing the hardness of the material.

Abstract

The Palm Oil Factory (PKS) is a factory that operates to process Fresh Fruit Bunches/FFB into several products, the main products of the palm oil factory are Crude Palm Oil (CPO) and Palm Kernel Oil (PKO). This research aims to measure temperature temperature in the distribution pipe between the turbine and the back pressure vessel which uses the observation method by observing directly. The results of this research show that on T1 on the first day the temperature was 161.5°C, on the second day there was a fairly low temperature drop at 142°C, on T2 it was not far from T1, on T3 there was a decrease in temperature in the boiler and at T4 there is a fairly low decrease and increase in temperature. Researcher Manarik concluded that a decrease in temperature between the distribution pipe between the turbine and the Back Pressure Vessel is a common occurrence in palm oil mills, and this can affect the operational efficiency and performance of the mill. Therefore, this research aims to determine the loss of heat energy. by conduction in the steam distribution pipe entitled "Analysis of Heat Loss by Conduction in the Steam Channel (Pipe) from the Turbine to the Back Pressure Vessel in a Palm Oil Mill (PKS) with a Capacity of 45 Tons/Hour"
