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.

With this educational opportunity it is hoped that the growth and development of students can achieve the expected goals. The success or failure of education in achieving its goals after evaluating the graduates produced by the school. If the graduates are in accordance with what has been set in the educational goals, then the educational effort can be said to be successful, and if on the contrary it is considered a failure in this case, it can be understood how important the assessment of learning is in education. Examination or assessment is an important component in education, especially learning assessment, and is important because assessment activities are carried out at least with the aim of knowing (1) the success of learning that has been implemented, (2) student abilities. and understanding of the material being studied, and (3) valuable information. Very useful as feedback for teachers in improving the learning activities that have been carried out. Likewise, if male and female students get high results because they answer all the test questions correctly, then the test questions need to be reviewed so that the test questions match the equation of difficulty percentage and ability percentage, from a height. Because the attributes of a proper evaluation are evaluations that consist of components such as validity, reliability, objectivity, practicality, difficulty level, and test item rating elevation. Therefore, it is necessary for every teacher to carry out a good evaluation process in teaching so that each achieves educational goals and improves educational problems, and the benefits of evaluation in teaching Arabic are available to all elements of the education system. The results obtained from this study are as follows: The researcher found that the form of the midterm exam questions for the Arabic language subject at Imam Muslim Islamic Boarding School was in the form of an essay test and there were ten questions in total. The researcher found a classification of difficulty level for each question, 7 moderate questions, and 3 easy questions, so it can be concluded that all questions are good and feasible to use. The researcher found the classification of the level of differential power that was ideal for each question, one question was not good, one question was limited to adequacy, 4 questions were good, and 4 questions were very good. It can be concluded that all questions are considered good and acceptable so that we can use these questions.
