Abstract

The sterilization process in the boiling of fresh fruit bunches (FFB) of oil palm is a critical stage in crude palm oil (CPO) production. The primary goals of this process are to soften the bunches, deactivate destructive enzymes, and facilitate the separation of the fruitlets from the bunch. However, deviations in pressure and boiling duration from the standard can lead to oil losses, where oil is carried away by the condensate. This study analyzes the impact of pressure and boiling conditions on oil losses during the three peaks of sterilization. Results indicate that increased pressure above the standard, particularly during the first and second peaks, significantly contributes to higher oil losses. Additional factors influencing these losses include the physical condition of the fruit, steam pressure fluctuations, and the quality and stability of the steam used. At the third peak, despite reaching a pressure of 2.8 bar, technical issues such as sterilizer leaks and unstable steam supply also led to variations in oil losses. In conclusion, minimizing oil losses requires strict control over pressure, the physical condition of the fruit, and steam quality during the sterilization process.

Abstract

Crude Palm Oil (CPO) is a vegetable oil extracted from the mesocarp or flesh of the oil palm fruit after several processes of oil and kernel separation. One of the key steps in CPO processing is the oil purification stage at the clarification station, where an essential piece of equipment used is the Oil Purifier. During this stage, the purification process is crucial because if the oil still contains impurities or a high amount of water, it can degrade the quality of the oil. Therefore, the Oil Purifier must be carefully managed in the CPO processing because this process involves separating oil, water, and impurities before the oil is pumped to the vacuum dryer. If the purifier does not function properly, it can negatively affect the quality of the oil produced. Hence, a reassessment of the Oil Purifier in the Clarification Unit is necessary. The procedure for analyzing the samples involves assessing the moisture and impurity content in AOP (After Oil Purifier) and BOP (Before Oil Purifier) samples. The results indicate that the feed temperature significantly affects the moisture content in the Oil Purifier's output. Additionally, the feed flow rate also has a substantial impact on the moisture content in the Oil Purifier's output, where the moisture content of the oil from the purifier is related to the moisture content of the feed oil entering the purifier.

Abstract

Nitrogen dioxide (NO2) contributes greatly as a precursor to a number of harmful secondary air pollutants including nitric acid, the nitrate portion of secondary inorganic aerosols and oxidants including ozone. Nitrogen dioxide gas (NO2) is an ambient air pollutant along with the element nitrogen monoxide (NO) which is usually produced from human activities such as burning vehicle engine fuel, burning rubbish, burning coal and industry. This research aims to monitor the quality of air pollution in industrial areas in East Jakarta. The NO2 content in the air can be determined using the UV-Vis spectrophotometer method based on SNI 7119-2: 2017. The principle of NO2 testing uses a UV-Vis spectrophotometer based on SNI 7119-2: 2017. From the results of the tests carried out, it can be concluded that the NO2 level obtained in sample 1 was found to be 25,153 µg/Nm3, in sample 2 the NO2 level was 28,371 µg/Nm3, in sample 3 the NO2 level was 107,022 µg/Nm3, in sample 4 the NO2 level was 29,720 µg/Nm3. Nm3, and in sample 5 the NO2 level was 83.446 µg/Nm3. Based on PP RI No. 22 attachment VII of 2021 concerning air pollution control, the quality standard for NO2 is 200 µg/Nm3 for 1 hour. So it can be concluded from the results of the tests that have been carried out that the NO2 levels in the environment are still below the quality standard, which means that it is not a source of NO2 pollution, is safe and meets the requirements for human health and the environment.

Abstract

One of the palm oil processing industries in West Sumatra has raw materials in the form of fresh fruit bunches that come from their own farms and the community. In the processing process, there is a problem of loss of palm oil in the production process. This will affect the quality of the product, so the quality in the production process needs to be controlled, which is boiling. Based on the results of preliminary observations, the boiling station experienced loss of palm oil in condensate water discharge and loss of palm oil in empty bunches. Loss of palm oil in empty bunches is set as a standard of <0.129% by the company. The analysis will be carried out related to quality control, especially in the boiling process of one of the Palm Oil Mills in Sumatra using the QCC (quality control circle) method. From the results of the Quality Control Circle analysis, it can be seen that boiling time and boiling pressure greatly affect the loss of palm oil. The longer the boiling time, the greater the loss of palm oil, while the lower the boiling pressure, the greater the loss of palm oil. There are several factors that cause the loss of palm oil in the boiling process, including machines, people, raw material factors and methods. The machine factor is the main factor because the sterilizing machine cannot operate optimally until the required pressure is not reached.

Abstract

CPO (Crude Palm Oil) is yellow-colored crude palm oil derived from the extraction or forging of palm fruit flesh. Factors that determine the quality of CPO production are the levels of free fatty acids, moisture content, levels of impurities. The purpose of the analysis is to analyze how big the deviation of quality of CPO that is free fatty acid content, water content and dirt level by using control chart chart mean (X) and control chart range (R), identify the cause of problem (deviation) of quality of CPO with a causal diagram (fishbone), and provide suggestions for improvement to improve the quality of CPO that occurred. Results obtained from 28 samples were the number of samples outside the control limit for ALB levels of 12 samples with percentage of 43%, water content of 10 samples with percentage 36%, and dirt level that is 6 samples with percentage 21%. The most influential cause when viewed with the fishbone diagram of raw material, machinery and human factors. From the analysis results can be concluded that the quality of CPO production PT X produced there is still data outside the control limit. The quality of CPO produced is influenced by raw material, human and machine factors.

Abstract

Crude Palm Oil (CPO) is a vegetable oil derived from the fruit of the oil palm plant. During the processing of palm fruit into CPO, sludge is produced as a byproduct of the oil purification process. This sludge is reprocessed in a sludge centrifuge because it still contains oil, with hot water added as a diluent to facilitate the separation between sludge and oil. The addition of hot water helps maintain the balance in separating sludge and oil. Low water content will cause the incoming feed to become thicker, making it difficult to separate the oil in the sludge centrifuge. The sludge centrifuge separates the oil in the sludge using centrifugal force. To date, the company has been adding hot water at a rate of 1.5 tons per hour, resulting in oil losses in the heavy phase ranging from 0.9% to 1%. Due to the high oil content in the sludge, a study is needed to evaluate the performance of the sludge centrifuge in processing the sludge to ensure that oil losses in the heavy phase meet company standards. The method used to analyze oil losses is extraction. The results show that increasing the amount of hot water reduces the percentage of oil losses. Additionally, the optimal oil loss percentage occurs at a hot water addition of 3 tons/hour.

Abstract

This study evaluates the efficiency of the Takuma N750 water tube Boiler at a palm oil mill, which has a maximum evaporation capacity of 27 tons per hour. Boiler efficiency is crucial for converting thermal energy from fuel into steam, with operational data showing significant efficiency variations. The average efficiency was 54.34%, substantially below the target of 80%, with the highest recorded efficiency at 60.4% and the lowest at 51.08%. The analysis revealed an inverse relationship between excess air and Boiler efficiency; as excess air increases, efficiency decreases. For instance, with 139.22% excess air, efficiency dropped to 56.36%, compared to 60.4% with 123.44% excess air. The study concludes that optimizing excess air levels is essential for improving Boiler efficiency, recommending adjustments to combustion parameters and excess air control to enhance performance and reduce operational costs. This research offers insights into better Boiler operation and energy management in palm oil mills.
