Abstract

PT Menthobi Makmur Lestari is a growing industrial company in the field of palm oil production. The company is targeting increased palm oil production to forecast capacity plans and manufacturing facilities. One of the prediction methods used is multiple linear regression. The free variables used for prediction are the age of the tree, land area (ha), number of trees, number of vines, and the bound variable is the yield of oil palm production. The results of the correlation test using multiple regression showed a significant correlation of 0.05 or less. Hypothesis testing includes multiple linear regression and correlation using the t test and f test with a significance level of α = 0.05. The value of multiple correlation analysis (R) is 0.947 and the coefficient of determination is 90%. The performance of the multiple regression equation is the accuracy of predictions with an average absolute error percentage (MAPE) of 21%, which is formed from the validation of training and testing data.

Abstract

Peneladi Village, Pana, Kapuas District, Sanggau Regency, West Kalimantan, is a center for oil palm plantations with high production potential. However, most farmers still rely on conventional cultivation methods that do not fully adhere to Good Agricultural Practices (GAP) standards. This impacts low productivity, the quality of fresh fruit bunches (FFB), and environmental sustainability. This community service activity aims to provide technical assistance and education on the application of GAP in oil palm cultivation, including land management, balanced fertilization, integrated pest management (IPM), and timely harvesting. Implementation methods include outreach, training, demonstration plots (demplots), and field assistance. The activity results showed an 85% increase in farmers' knowledge and skills based on pre- and post-test evaluations, as well as the implementation of more environmentally friendly and efficient cultivation practices. Farmers began implementing a fertilizer system based on soil analysis results, proper frond pruning, and mechanical weed control to reduce herbicide use. This activity contributed to increasing farmer awareness of the importance of sustainable production and environmental management. Going forward, it is hoped that GAP implementation can be consistently implemented to increase oil palm productivity in Penyeladi Village, maintain the quality of fresh fruit bunches (FFB), and preserve ecosystem sustainability.

Abstract

This study investigated the effect of the sterilization time of Fresh Fruit Bunch (FFB) on the Free Fatty Acid (FFA) content in Crude Palm Oil (CPO). It evaluated its implications for sterilization asset performance. A laboratory-scale experiment was conducted using a manual steam sterilizer heated by a gas stove, resulting in fluctuating sterilization temperatures. Three sterilization durations (30, 45, and 60 min) were tested, each with two replicate groups. Crude oil was extracted using a hydraulic press, and FFA content was determined using alkali titration 0.2 N NaOH and phenolphthalein indicator. The results showed considerable variation in FFA content among treatments. The lowest FFA value (2.50%) was obtained in the 60-min treatment and was the only result that complied with the Indonesian National Standard (SNI 01-2901-2006), which limits FFA content to 5.00%. In contrast, the highest FFA values reached 13.13% and 13.30% in the 45-min and 60-min treatments, respectively. These findings indicate that temperature instability during sterilization had a greater impact on FFA formation than sterilization duration. From an asset management perspective, sterilization equipment is a critical asset whose operational performance directly influences product quality. Therefore, maintaining stable sterilization temperatures is essential for minimizing FFA formation and ensuring consistent CPO quality.
