ABSTRACT Indonesia is currently the largest palm oil producer in the world with a production of around 3,855,000 tons/year This study discusses the potential and quality of palm oil based on the duration of fruit storage . , 2, 3, 4, 5, 6 and 7 day. The research was carried out from November to December 2023, at PT Inti Guna Nabati. Sarolangun. South Sumatra. The parameters measured for oil potential are crude palm oil (CPO) content, and the quality of palm oil measured is the bleaching regression index (DOBI), free fatty acid content, and moisture content from northern FFB suppliers (Rasau B2 Pamenang Village. Merangin Distric. and southern FFB suppliers (Setia Marg Village. Muara Lakitan Distric. Free fatty acids are determined by titration, and moisture content is measured with an electronic moisture analyzer. The purpose of this study is to find out the quality of the two FFB suppliers that are good and suitable for further processing at PKS IGUN. It will be better to bring FFB 1-2 days after harvest directly to the mill because the quality still meets the criteria of the IGUN mill. The results of the study show that the quality potential of FFB is the longer it is stored, the higher the FFA level, the lower the moist, the lower the DOBI. Based on the results of the study, the length of fruit storage has a bad effect on the quality of palm oil. Based on the results of CPO research from Rasau B2 Pamenang Village. Merangin District for FFA 2. 00 and DOBI 1. 712, while the results of CPO research from Setia Marga Village. Muara Lakitan District are FFA 2. 48, moist 0. 47 and DOBI 1. Of the two research results, the CPO results from Rasau B2 Pamenang Village. Kec are better. Keywords : palm oil. FFA, laundry, moist INTRODUCTION The oil palm (Elaeis quinensis Jac. is a tropical plant belonging to the Palmae family and native to West Africa. However, there are those who state that oil palm comes from the United States, namely Brazil because more oil palm species are found in Brazilian forests compared to Africa. (Yan Fauzi, 2. In general, there are two types of palm oil, namely palm oil derived from the extraction of fruit pulp . and palm oil derived from the extraction of palm kernel . The result of fruit pulp extraction is called crude oil or Crude Palm Oil (CPO), while the result of fruit core extraction is called kernel or PKO (Palm Kernel Oi. Crude Palm Oil (CPO) is the result of processing the pulp of oil palm fruit. In the form of a rather thick oil with a reddish-yellow-orange color. (Ardha Panca Wardanu, 2. Among the businesses owned by Dharma Agung Wijaya (DAW) Group, in addition to being engaged in energy and resources, it also has a business in the plantation sector and owns several palm oil mills (PKS) spread across Sumatra and Kalimantan. PT Inti Guna Nabati (PT. IGUN) is one of the units of the company engaged in oil palm (Feby Yuliantika, 2. PKS Inti Guna Nabati is one of the 4 factories owned by Dharma Agung Wijaya (DAW) which was taken over from PT MAS (Mitra Agroila Sejahter. In the FFB processing process, the IGUN Palm Oil Mill (PKS) has a processing capacity of 30 tons/hour. In accordance with the purpose of establishing the palm oil mill, it is to carry out activities to process palm oil Fresh Fruit Bunches (FFB) into palm oil or Crude Palm Oil and Palm Kernel (Kerne. (Feby Yuliantika, 2. In the palm oil processing process, the quality of the processed products is highly determined by the raw materials. Palm oil processing requires good quality both qualitatively and quantitatively. The low quality of palm oil is largely determined by many factors. These factors can be directly from the nature of the parent tree, post-harvest handling, transportation and errors during processing. Jurnal Reaksi (Journal of Science and Technolog. Jurusan Teknik Kimia Politeknik Negeri Lhokseumawe Vol 22 No. Desember 2024 ISSN 1693-248X Quality control is one of the most important functions of a company to be able to win competition in the industrial world. Quality control activities are expected to help companies maintain and improve the quality of their products by controlling the level of product defects to the level of zero defects. Therefore, these quality control activities can be carried out starting from raw materials, during the production process to the final product and adjusted to the set standards. Quality standards are the most important thing to determine good quality palm oil. Good palm oil quality must have several factors that determine its quality standards, such as the content of Free Fatty Acids (FFA). Moisture and Dirt. The oil palm plant which is the raw material for the Inti Guna Nabati PKS is the Tenera variety of palm oil, because from an economic point of view the Tenera variety produces high oil, so that it benefits the mill. The quality of palm oil production as a food ingredient has quality aspects related to the parameters of fatty acid content, moisture content and dirt content. Palm oil mills are operated in a continuous series, where the results of the previous process are carried over to the next. Mistakes in the initial process will get bad results in the next process. Free Fatty Acids (FFA. are acids that are released on hydrolysis from fats. There is a wide variety of fats, but for calculations, palm oil's FFA content is considered to be Palmitic Acid . olecular weight Moisture content is the amount of water content present in the sample. Moisture content can affect the quality of CPO, the higher the moisture content, the lower the quality of CPO. Impurity levels are insoluble substances in oil, which can be filtered after the oil is dissolved in a solvent. The content of free fatty acids (FFA), moisture content and impurities in palm oil in storage tanks or storage tanks before being marketed are analyzed to determine the quality of palm oil. In this case, the cleanliness of the storage tank needs to be maintained, by washing it 2 times in 1 year to reduce the increase in free fatty acid levels, moisture content and dirt levels. In PKS IGUN itself does not have its own garden, so the raw materials that go to the PKS only rely on FFB from local farmers. The obstacle is the quality or quality of the FFB of the farmers. Lack of understanding of farmers regarding harvesting based on the level of fruit ripeness. And the company itself has not been able to provide quality standards to farmers so that farmers only refer to the color of FFB . and directly send the FFB to the mill. At PKS IGUN, analysis is carried out every day to determine the quality of CPO. After analysis. CPO can be sent directly to be marketed, because the longer CPO is stored in the storage tank, it will cause the low quality of the CPO, unless there are obstacles such as transportation and damaged roads that do not allow oil to be shipped or marketed with the record that the selling price of palm oil is cheap. In this study, the author conducted research for 4 days, because within 4 days it was possible to know the quality of the CPO that had been processed and would be sent or marketed by PKS IGUN every day. An increase in the level of free fatty acids can also occur in the hydrolysis process in the factory, in which chemical decomposition occurs assisted by water and takes place under certain conditions. Hot water and steam water at a certain temperature are auxiliary materials in the processing process. However, a less careful processing process results in unwanted side effects, the quality of the oil decreases because water at certain temperature conditions does not help the processing process but instead decreases the quality of the oil. Based on the description above, a study was conducted with the title "The Effect of Storage Time and Origin of Raw Materials on CPO Quality on FFA. DOBI and Moist Parameters in PKS Inti Guna Nabati".

Figure 3 shows that based on the results of the analysis, the treatment of the length of the fruit storage time for 7 days, is significantly different from the results. This means that the treatment of the length of the fruit storage time has a significant effect on the content of palm oil-free fatty acids. The longer the fruit is stored, the higher the content of palm oil-free fatty acids. From the results of the study, it is known that the average increase in palm oil-free fatty acids for fruit storage for 1 day, 2 days, 3 days, 4 days, 5 days, 6 days and 7 days in a row for suppliers from the north is 0. 06%, 0. 10%, 0. 10%, 0. 13%, 0. 33%, 0. 12% and suppliers from the South is 0. 13%, 0. 33%, 0. 13%, 0. 58% and 0. The main factor that determines the fatty acid content is the age of the fruit used to process the oil. The longer it is stored, the higher the contamination, damage, and free fatty acid content of the oil. Man and Moh . stated that free fatty acids in palm oil (CPO) can increase due to enzyme activity in palm fruit and lipase microbes. The Ministry of Industry . stated that high-quality palm oil has a content of no more than 2% free fatty acids, and the standard quality of free fatty acids is not more than 5%. Quality palm oil will produce the lowest free fatty acid content of around Laundry Value Analysis Heat the oil sample from oil palm fruit extraction at a temperature of 60-70 C until it looks dilute and homogeneous, then weigh the oil sample as much as 0. 2 g into a volume of 50 ml, then add nhexane to the limit of the volumetric flask and shake the solution to combine the oil and n-hexane . , and measure the arbonsiness of the sample using a spectrophotometer.
