Abstract

Penelitian ini bertujuan untuk menganalisis kedudukan hukum Badan Penyelesaian Sengketa Konsumen (BPSK) sebagai lembaga quasi yudisial dalam penyelesaian sengketa konsumen di Indonesia. Dengan menggunakan metode penelitian yuridis normatif dengan memanfaatkan bahan hukum primer, bahan hukum sekunder dan tersier. Penelitian ini menyimpulkan bahwa sifat putusan BPSK yang final dan mengikat pada dasarnya tidak sesuai dengan makna final dan mengikat pada suatu putusan lembaga pengadilan. Hal ini menunjukkan bahwa status dan kedudukan unit BPSK dinilai berdasarkan persepsi administratif karena hanya memiliki kewenangan administratif sehingga keputusan tersebut mengasumsikan tidak dapat menjalankan kapasitas hukum apapun. Dengan demikian BPSK dapat dikategorikan sebagai lembaga quasi-judicial dan sifat putusannya tidak sama dengan sifat putusan pengadilan utama.

Abstract

Oil palm processing is one of the factors that determine the success of an oil palm plantation business. The Palm Oil Mill (PKS) in the context of the palm oil industry in Indonesia is understood as the unit of extraction of Crude Palm Oil (CPO) and palm kernel from the Fresh Fruit Bunches (FFB) of oil palm. The Palm Oil Mill (PKS) is the most upstream processing unit in the palm oil processing industry and is a critical point in the economic life cycle of palm fruit in particular and the palm oil industry in general. The purpose of this study was to find out how much percentage of palm oil loss was contained in the dregs of the press and to find out the optimal conditions for the screw press. The high or low percentage of oil loss in the process that occurs is influenced by several factors, namely the condition of the working pressure on the screw press and the capacity of the diluent water. The average percentage of loss of palm oil in the pressing process obtained from the data is June 5.07% with the norm of losses of pressed waste oil of 0.64%, the average of July is 4.92% with the norm of losses of pressed oil of 0, 64%, and an average of 4.98% in August with a normal loss of 0.64% of pressurized oil losses.

Abstract

Water is a crucial factor in ensuring smooth and high-quality production in palm oil mills. Minerals present in water can lead to scale formation, sedimentation, and equipment corrosion. Therefore, the demineralization process with cation and anion regeneration is beneficial to maintain water quality in accordance with op- erational standards. Water plays a vital role in the industrial sector; boilers, as primary steam generators, transform water into vapor through heating. However, operating without good water quality can result in issues like scale formation and corrosion. In water treatment processes, chemical substances are required for purification, such as Nalco 3276 for flocculation and Nalco 8173 for flocculant retention. The mineral content in water also affects chemical reactions, such as causing scale formation in boilers and influencing reaction processes. Demineral- ization is frequently employed across various industrial sectors, including palm oil mills, to treat boiler feedwater and other raw materials. Maintaining stable boiler feedwater usage by controlling pH and total hardness prevents problems in pipelines. This research focuses on cation and anion regeneration to reduce min- eral content in boiler feedwater at PT. Bakrie Sumatera Plantations, Tbk Palm Oil Mill Kisaran, with the aim to analyze the regeneration process using H2SO4 and NaOH dosages and identify factors causing issues during regeneration.

Abstract

Boiler blowdown is the removal of a portion of the water in a steam boiler which has a high TDS concentration and replacing it with new boiler feed water so that it will reduce the concentration of suspended or dissolved solid water from the boiler. The working system in the boiler is that heat is channeled to boiler water which will then form steam. Water has an important role in the boiler, if the water used is not according to standards it will cause problems such as scale, corrosion, deposits, carry over and other specific problems. In general, the water fed to the boiler contains a high content of TDS and other dissolved and insoluble solids in it. From this research it is known that during April, May and June the highest blowdown rate occurred on April 12, 2022, namely 2183.76 kg/hour and for the lowest blowdown rate occurred on June 7, 2022, namely 684.91 kg/hour. The highest blowdown time occurred on 12 April 2022, which was 0.74 minutes/hour or equivalent to 44.4 seconds, and the lowest blowdown time occurred on 07 June 2022, namely 0.23 minutes/hour or equivalent to 13.8 second. The high TDS value can affect the blowdown rate, blowdown time and blowdown percentage which will have an impact on the effectiveness of the blowdown rate, blowdown time and blowdown percentage in the boiler itself.

Abstract

Turbin uap merupakan sumber energi atau penggerak mula yang mengubah energi potensial menjadi energi kinetik kemudian mengubah energi kinetik tersebut menjadi energi mekanik berupa putaran poros turbin. Untuk melihat kemampuan turbin dalam mengubah energi kalor menjadi energi mekanik maka perlu diketahui perbandingan antara kerja aktual dengan kerja ideal yang disebut dengan efisiensi isentropik. Nilai efisiensi isentropik dipengaruhi oleh tekanan uap dan temperatur masuk turbin, laju massa uap, daya dan desain turbin. Pada penelitian ini diperoleh efisiensi isentropik turbin uap berdasarkan data spesifikasi sebesar 44,09% dan nilai efisiensi isentropik tertinggi pada saat turbin uap beroperasi sebesar 22,16%. Pada saat beroperasi diperoleh efisiensi tertinggi pada tekanan uap masuk sebesar 27 bar, tekanan uap keluar sebesar 3,4 bar dan kualitas uap sebesar 0,866. Tingginya efisiensi isentropik turbin uap dipengaruhi oleh temperatur, tekanan uap masuk dan tekanan uap keluar, serta umur atau umur turbin yang digunakan pada pabrik pengolahan kelapa sawit.

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.
