Abstract

This study aims to determine soil pH values using various dilution levels with water (H₂O) and 1 N KCl solution, and to analyze their effects on soil acidity and its implications for soil fertility. Soil pH is an important indicator that influences nutrient availability and plant growth, particularly in oil palm cultivation. The research was conducted in an ITSI Soil Laboratory by mixing air-dried soil with H₂O and KCl in ratios of 1:1 and 1:2.5. The results showed that soil pH mixed with water ranged from 5.3 to 5.8 (slightly acidic), while soil mixed with 1 N KCl had lower pH values, ranging from 4.2 to 4.4 (strongly acidic). The decrease in pH when using KCl solution is due to the exchange of H⁺ and Al³⁺ ions from soil colloids into the solution, resulting in increased soil acidity. This condition can reduce nutrient availability, suppress microbial activity, and potentially lead to toxicity in plants if not properly managed. Therefore, soil pH management through liming is necessary to achieve optimal conditions for plant growth.

Abstract

Palm Oil Mill Effluent (POME) is a major by product of the palm oil industry, characterized by high organic content (COD 40,000 - 100,000 mg/L) and significant environmental risk if untrated. This study aims to Optimize POME conversion into biogasthrough anaerobic digestion, focusing on technical parameters (COD, pH, temperature) at PT Tunas Baru Lampung. Using a quantitative approach, data were collected over 12 months and analyzed via multiple linear regression. Results indicate COD as the dominant factor (β = 0.866, p=0.000), with optimal biogas production at pH 6.8 - 7.4 and mesophilic temperatures (30–40°C). The estimated electricity potential reached 54.62 MW/month, reducing CO₂ emissions by 21,533 tons/year. Challenges include infrastructure limitations and regulatory gaps. Recommendations include adopting advanced digester technologies, policy incentives, and further industrial-scale research. This study contributes to green manufacturing by aligning waste management with renewable energy goals and circular economy principles

Abstract

Each cooking oil has differences, especially in the content of antioxidant compounds. Oil with high antioxidant content can reduce oil damage during the process of use. The content of antioxidant compounds in red palm oil and cooking oil can cause oil damage in red palm oil and cooking oil also varies. The study aims to determine the effect of oil type on antioxidant levels in red palm oil with the deep fat frying method and to determine the difference in temperature affecting antioxidant levels in cooking oil with the deep fat frying method. This study was conducted using the Completely Randomized Design method in factorial form, with 2 treatment factors. The first treatment is the type of oil (M) consisting of M1 = red palm oil (RPO) and M2 = palm cooking oil (PO). The second factor is the variation of frying temperature with the deep fat frying method with 4 levels, namely: S1 = without frying (control), S2 = 180 ° C, S3 = 230 ° C and S4 = 280 ° C. Data analysis was carried out descriptively. The results of the study showed that red palm oil has a higher antioxidant content compared to palm oil and cooking oil with the deep fat frying method. Red palm oil has a DPPH percentage of 28.01%, while palm cooking oil has a DPPH percentage of 28.90. The lower the DPPH percentage, the higher the antioxidant content. The antioxidant content of red palm oil and cooking oil with the deep fat frying method differs with increasing frying temperature. Red palm oil experiences a decrease in antioxidant content with increasing frying temperature, while palm cooking oil experiences an increase in antioxidant content with increasing frying temperature.

Abstract

The palm oil industry plays a vital role in the Indonesian economy, with palm oil (CPO) and palm kernel (PKO) yields as indicators of processing efficiency. This study aims to analyze the yield of CPO and PKO at 30 ton/hour PKS through a quantitative approach with field methods and laboratory tests. Raw and boiled Fresh Fruit Bunch (FFB) samples were taken from 30 ton/hour PKS in Langkat Regency, North Sumatra, then analyzed using material balance, moisture content, oil extraction (soxhletation), and kernel separation. The results showed that the average CPO yield on raw FFB was higher (32.12%) than that on boiled FFB (23.94%), while the PKO yield on boiled FFB (7.74%) was superior to that on raw FFB (3.84%). Factors such as fruit maturity, sterilization process, and extraction efficiency have a significant effect on yield. The findings recommend optimizing the quality of raw materials and processing processes to increase productivity. This study provides a scientific basis for mill in performance evaluation and yield improvement strategies

Abstract

Oil losses in crude palm oil (CPO) production significantly impact process efficiency and industrial profitability. This study analyzes the causes and extent of oil losses at various processing stages, including empty fruit bunches, pressed fiber, nuts, and liquid effluent, using Soxhlet extraction with n-hexane solvent. Results indicate that while total oil losses remain within acceptable limits, certain components such as empty fruit bunches and liquid effluent exceed standard thresholds. Key contributing factors include raw material quality (underripe or residual fruit), equipment inefficiencies (such as digester maceration and centrifuge separation), and operational errors. The Soxhlet extraction method proved effective in measuring oil losses due to its ability to separate compounds based on density differences without damaging oil components. This study recommends improvements in sterilization processes, equipment optimization, and enhanced operational monitoring to reduce oil losses. The findings provide valuable insights for the industry to enhance production efficiency and minimize economic losses

Abstract

This study aimed to determine the effect of fruit maturity levels on the oxidative color stability of crude palm oil (CPO) during heating. Fruit conditions used were unripe, ripe, overripe, and bruised. Samples were heated at 100°C for 0, 6, 12, 18, and 24 hours. The peroxide value and color (Red-Yellow) were measured using Lovibond Tintometer. Results showed that the combination of ripe and overripe fruits had the highest stability in red and yellow colors, while mixtures involving bruised and unripe fruits showed significant degradation. Prolonged heating accelerated the degradation of carotenoid pigments. The study indicates that fruit maturity significantly affects the oxidative stability of palm oil color.

Abstract

Palm oil and red palm oil are food ingredients that are rich in essential nutrients such as vitamin E and carotene. This study aims to analyze the levels of vitamin E and carotene in red palm oil and palm oil after deep fat frying with different temperature variations. The deep fat frying process was carried out at temperatures of 32°C, 180°C, 230°C and 280°C to determine the effect of temperature on the nutritional content. Analysis of vitamin E content was carried out using the UV-Vis spectrophotometry method, while analysis of carotene levels was carried out using the spectrophotometry method. The results showed that there was a decrease in vitamin E and carotene levels in both types of oil along with increasing frying temperature. A more significant decrease occurred at temperatures from 32°C to 180°C compared to temperatures from 230°C and 280°C. In addition, red palm oil has higher levels of vitamin E and carotene compared to palm oil at all temperature variations. These findings indicate the importance of considering temperature in the frying process to minimize nutrient loss in cooking oil, especially in oils with high vitamin E and carotene content such as red palm oil.

Abstract

Blanching at initial process can be done at the beginning before the process so that it will maintain the quality. Blanching is done to inactivate the endogenous lipase enzyme so that the rate of formation of free fatty acids and volatile compounds from the oil is inhibited. Blanching treatment affects Free Fatty Acids (FFA) and Deterioration Of Bleachability Index (DOBI). This process is a preliminary treatment before the fruit is processed in the factory. This study aims to determine the effect of blanching treatment on fruit bunches to maintain CPO quality from increasing Free Fatty Acids (FFA) and maintaining the Deterioration Of Bleachability Index (DOBI) value. This research was conducted in the PTPN IV laboratory, MAYANG PKS Unit. The time of this research was carried out from June to August 2022. This study used the Completely Randomized Design (CRD) method, the first independent variable is blanching time with three levels, namely 0, 10, and 20 minutes. The second independent variable is the storage time which also consists of three levels, namely 0, 24, and 48 hours. Samples with 20-minute blanching treatment showed the lowest ALB levels of 7.72% and a DOBI value of 2.53.
