In general, solid waste from the palm oil industry contains high organic matter, which has an impact on environmental pollution. Improper handling of waste will pollute the environment. Various efforts have been made to process and increase the economic value of palm oil solid waste. Palm oil waste is the residue from the oil palm plant which is not included in the main product or is a by-product of the palm oil processing process, either in the form of solid waste or liquid waste. Oil palm solid waste can be in the form of empty fruit bunches, shells, bfiber and palm fronds. This research was carried out as an innovation from the previous research process with a differentiator, namely palm fronds, which in previous studies used empty palm oil bunches as raw material. In this study, hydrogen peroxide was used as a factor to determine the quality of paper made from palm fronds. Bleaching is a process of removing the color contained in the fiber due to the presence of lignin in the pulp with the help of chemicals. With three different concentration treatments aimed to determine the difference in the degree of whiteness, grammage and moisture content of the paper. Based on the results of the analysis of variance, it showed that the effect was significantly different on the concentration of the bleach solution (H2O2) with a variation of the concentration of 8% on the grammage with the highest grammage of 4% and 6% concentrations, and also had the lowest water content but at a concentration of (H2O2) 4% and 6% have higher water content.

Unproductive oil palm stems can produce Umbut which is the raw material for bioethanol production. In general, the production process of bioethanol from lignocellulosic materials includes oil palm stalks. The bioethanol production process goes through several stages of physical, chemical or biological pretreatment, polymer saccharification, sugar fermentation, and ethanol separation and purification. This study aims to determine the production of bioethanol from oil palm stems (Elaeis Guineensis Jacq) through a pretreatment process using H2S04 and fermentation using baker's yeast (Saccharomyces cerevisiae). The method used in this study was a Completely Randomized Design (CRD) Non Factorial with 3 treatment levels and 1 control, and 3 repetitions (Triplo) with a total sample of 12 samples. The resulting bioethanol is then tested (moisture content, yield, and pH). The resulting data were analyzed using ANOVA and Duncan's test. Based on the results of this study, the best treatment was found in the H0 treatment with a yield of 34.5%, 1.52% moisture content and 5,6 % pH

Palm Oil Mill Effluent (POME) is abundantly available in the palm oil industry and has significant potential for generating renewable energy, specifically biogas, through the biogasification process. This study investigates the relationship between the reduction of Chemical Oxygen Demand (COD) values and pH changes in POME during the biogas production process. The study employs a Completely Randomized Design (CRD) with a single factor and four levels. Data were analyzed over five observation periods spanning 24 days. The results show a significant decrease in COD concentration from 96,300 mg/L on day 0 to 22,720 mg/L on day 24. This reduction is attributed to microbial activity, with Effective Microorganisms (EM4) being used in this research. Additionally, an inverse relationship between pH and COD was observed, where an increase in pH correlated with a decrease in COD. Biogas production also increased over time, with the cumulative biogas volume reaching 5.2 liters on day 24. The study concludes that more alkaline environmental conditions support the activity of microorganisms responsible for COD reduction and higher biogas production. Recommendations for future research include adding parameters such as temperature and Volatile Fatty Acids (VFA), and further investigation into more effective and efficient microorganism seeding. Thus, this research provides insights into the biogasification process and the development of more efficient and sustainable biogas technology.

The results showed that liquid smoke grade 2 of palm oil shells were able to reduce the content of free fatty acids in crude palm oil. The results of the best free fatty acid levels found in the sample of the spray treatment method decreased by 0.38% and the combination decreased by 0.52%, the results obtained were greatly decreased and met the Indonesian National Standard 01-2901-2006. The water content and dirt content produced are still very high, the lowest average water content is obtained by sample B2 with a result of 0.94% and the highest average result is obtained by sample A, which is 0.99% and the result of dirt content with an average result The lowest average was obtained by sample B with a result of 1.38% and the highest average result was obtained by sample B2 with an average result of 4.2%. The results of high water content and dirt content were caused by obtaining crude palm oil by pressing using a manual tool with a cloth so the results obtained did not meet the Indonesian National Standard 01-2901-2006, namely 0.5%. Then the results of DOBI levels (Deterioritation Of Bleachability Index) were obtained with the lowest result of 2.56 from the results of sample B1 and the highest result of 2.25 ppm from the results of B3, if it is associated with the quality of the oil obtained is still not sufficient, it is still not meeting the standards set. determined by PORIM (Palm Oil Research Institute of Malaysia) which is 2.36 – 3.24. For the level of carotene produced, it is still not enough, namely, the lowest average result is 4.26 ppm from sample B3 and the highest average result is obtained by sample A, which is 488 ppm, so it still does not meet the quality standards of carotene parameters according to Palm Oil Refiners. Association of Malaysia (PORAM) which is 500 - 700 ppm.

The Continuous Settling Tank (CST) is a tank at the clarification station of a palm oil mill used for the sedimentation process of oil, water, and sludge. The optimal performance of the CST is evaluated based on the overflow produced, considering the quality of water content and the level of oil impurities according to standards. Controlling the percentage of impurities in the oil requires an optimal thickness level during collection. The thickness of the fluid layer in the CST tank can be measured using a bamboo stick. However, the bamboo used to measure the fluid thickness is inaccurate because the bamboo inserted into the CST tank, with the expectation that sludge will adhere to it, is often cleaned by the oil layer, and the bamboo has to be inserted repeatedly, making it inefficient. Therefore, it is necessary to create a device to measure oil thickness based on Archimedes' principle, using a float. The objective of this research is to create a measuring device to control the quality of crude oil in the Continuous Settling Tank based on the oil thickness. The design of this research uses two methods: descriptive and experimental. The research results show that after the implementation of the measuring device as a thickness indicator, oil quality control in the CST becomes efficient. With an oil thickness of 50 cm, the average quality of crude oil is observed to be the best, with a water content of 0.45% and an impurity level of 0.49%.

Acceleration of processing for fresh fruit bunches (FFB) is crucial to increase profitability and business opportunities for oil palm farmers. This research aims to evaluate the effect of using gamal (Gliricidia sepium) leaves and the duration of ripening on the percentage of FFB processing as well as the quality of crude palm oil. This study employed a factorial completely randomized design (CRD). The data were analyzed using ANOVA with Duncan’s Multiple Range Test at a significance level of 5%. The results of the analysis showed that the best treatment was S3T2 (40% gamal leaves, 20 h of ripening) with a natural processing percentage of 45.87% of the FFB weight and 60.34% of the total bunch weight. The use of gamal leaves and the duration of ripening significantly affected the quality parameters of the oil, especially the free fatty acid content. Treatment S1T1 (20% gamal leaves, 10 h of ripening) showed the best results with a free fatty acid value of 1.30%, meeting the quality standard (<5%). However, the moisture content still exceeded the quality standard (<0.5%), although treatment S3T2 yielded the best result at 0.63%. While, the impurity content quality met the quality standard (<0.5%), with the best value achieved by treatment S1T1 at 0.15%.
