Oil palm empty bunches (TKKS) are solid waste from palm oil processing which is quite large and until now its utilization is still not optimal. Therefore, it is necessary to innovate the processing technology of oil palm empty bunches in order to produce products that have more usefulness and high economic value as well. One of the processed products from the solid waste of oil palm empty bunches is composite. By utilizing solid waste of oil palm empty bunches (EFB) to be used as a base material for making (filler) and BTQN 157 EX resin as a matrix, catalysts as hardeners and glass fibers (fiberglass) as reinforcement are expected to produce composite boards that have proven quality by testing. impact standard ASTM E23. This research was conducted at the STIPAP TPHP Laboratory and the Laboratory of Basic Phenomena of Mechanical Engineering, the Medan Institute of Technology (ITM). The research period was 2 months, namely July - August 2019. This research used handmade methods and charphy impact testing with a composition of 29% OPEFB fiber, 157 ex 70% BTQN resin, 1% catalyst and glass fiber. The results showed that the average absorption energy of the 8 samples was 0.833 Joules and the average impact price was 0.0108 joules / mm2.

In the last 10 years, the Palm Oil Mill (PKS) in Indonesia has grown very rapidly. Most of the large names of oil palm plantations have gradually changed throughout Indonesia to oil palm plantations. One of the processes to achieve efficiency in the Palm Oil Mill can be determined in the fruit ripening process. Where the perfection of the ripening process is influenced by the condition of the fruit and the ripening system. One of the problems that need to be faced in the vertical boiling process is the occurrence of losses or also called oil loss in the condensate air. Oil losses can occur due to various factors, including differences in fruit sources processed in the PKS. In this study, a factorial complete randomized planning method will be used which has two factors. The highest losses are in third party fruit/community fruit with a total of 11.04%, and the lowest total losses are in core plantation fruit with a total of 4.8%. The highest oil losses are in third party fruit or community fruit, this is due to the length of time the fruit has been sorted overnight which can cause the fruit to be overripe and also in fruit that is injured by the loader. The results of this analysis show that the double peak system has a significant impact on oil losses to third parties/community members.

Oil palm plantations are widespread in Indonesia, triggering the birth of many palm oil processing industries, so that this plant becomes a commodity for the country. Palm oil factories process fresh fruit bunches (FFB) which will later produce crude palm oil (CPO) and palm kernel oil (PKO) as derivative products. Based on my experience and information, kernel processing in PKS cannot be fully maximized. Because many kernels are heated for a very long time so that the cost of production is high, and also many kernels are abandoned, moldy and smell rancid because the quality of the kernel is not fully achieved. In this case, the best processing of the kernel is needed. So that the quality of the kernel can be achieved. In this final assignment, it will be analyzed how the quality of the kernel is if heated with time and temperature below previous research. So that the kernel quality will be obtained according to SNI 01-000201- 1987 with lower energy consumption. This study will use a non-factorial random design method because it only has 1 factor, namely temperature variation (70 OC, 80 OC, and 100 OC).

This Community Service Program was conducted to introduce and implement hydroponic technology that utilizes waste from Nile tilapia farming as a source of organic fertilizer. This activity was located in Dolok Sagala Village, Dolok Masihul District, Serdang Bedagai Regency. The method used in this PKM included training and direct mentoring of the community in creating and managing a hydroponic system for cultivating Brassica Rapa plants. This activity showed that the hydroponic system using fish waste as organic fertilizer produced high-quality Brassica Rapa plants. Additionally, this program provided the community with new knowledge about the benefits and potential of hydroponic technology as a modern agricultural solution in limited land areas. The success of this program is expected to be adopted more widely by the community to enhance local food security and economic welfare.

To increase palm oil production, special attention must be given to various factors that influence plant growth. One crucial step is ensuring optimal care for immature plants to improve their quality and yield. Unfortunately, many smallholder palm oil farmers face limited knowledge and resources to apply proper care practices. Therefore, targeted efforts are needed to help them understand the importance of palm oil plant care to sustain and enhance the profitability of this sector. In Bukit Cermin Hilir Village, Dolok Masihul District, Serdang Bedagai Regency, palm oil plant care uses two main techniques. The first technique is pruning, which involves removing fronds below the fruit bunches. This process facilitates pollination, increases the number of fresh fruit bunches, eases harvesting, and prevents excessive evaporation during the dry season. The second technique is circle clearing, which involves clearing a circular area around the palm tree with a radius of 0.6–1.5 meters to prevent weed growth that could disrupt the plants. Pruning is categorized into three types based on the plant’s age: initial pruning, production pruning, and maintenance pruning. The number of fronds left on each tree ranges from 28 to 54. These care practices optimize plant growth, simplify farm management, and contribute to producing higher-quality palm oil yields.
