Indonesia one of the plants that leaves and seeds grow has many useful benefits for human life, namely candlenut. The post-harvest handling of candlenut at the farm level it is generally still done traditionally where candlenut is drying on the floor or by direct exposure to solar radiation. They need approximately 7-9 days to get the appropriate drying results. Candlenut drying is influenced by the intensity of solar radiation on temperature and drying time according to the required hazelnut content. the dry hazelnut can use solar radiation power that is solar dryer. Absorbent plate is one component that is very important because it functions to absorb the intensity of solar radiation and convert it into heat energy and move it to the workpiece (candlenut) above it. In this study, testing was done on variations of the absorbent plates of zinc, aluminum and iron as well as variations in the thickness of the absorbent plates. Data collection starts at 09:00 until 15:00 WITA in sunny weather conditions. The results showed that the aluminum absorbent plate with a thickness of 0.04 mm was more effective and efficient in drying the candlenut to increase the productivity of the candlenut. The highest absorbent plate temperature and drying time were found on the aluminum absorbent plate with a thickness of 0.4 mm that is 72.36 oC and a drying time of 6 hours and meets the standard of moisture content of candlenut solution, which is 5.3%.

Determining the optimal route is very important in distribution of goods or services, because it can reduce costs and time. CV. Al-Zaman is a company that distributes urea fertilizer in Sumbawa Regency. So far, the company has never determined the shortest route in fertilizer distribution. This research will analyze the determination of the shortest route of distribution of fertilizer by CV. Al-Zaman, whose distribution route was previously modeled into the Vehicle Routing Problem (VRP) model, then the model was solved using the Saving Matrix method in determining the shortest route. So far, the distribution process is based on the driver's experience without analyzing the shortest route first. The distribution is carried out by 15 vehicle fleets with a capacity of 10 tons. The distribution process carried out by the vehicle fleet starts from the warehouse to all destination stores (vertex) and then returns to the warehouse. The results of the analysis using the Saving Matrix method and the VRP model resulted in savings of 75.1 km from the routes that have been used by the company.

Feed is all that can be eaten by livestock, both in the form of organic and inorganic materials, which can be partially or completely digested and does not interfere with health. Good feed is feed that contains quality food substances, such as energy, protein, fat, minerals and vitamins, to produce high-quality and high-quantity meat products. 70% of production costs are spent on feed. Therefore, assistance and training are needed so that the use of feed is efficient and meets the nutritional needs of livestock. The activity was carried out on August 4, 2020, located in the Sebewe Village, Moyo Utara District, Sumbawa Regency, West Nusa Tenggara Province. The activity method is in the form of Problem-Solution and Demo directly to the community. This activity began with the delivery of material on livestock rearing management (mating management), weaning management, management of feeding and care, then continued with activities giving material on cattle feed formulations, demos of making cattle feed and operation and maintenance of animal feed machines (concentrates). The conclusion from this activity is that farmers in Sebewe Village, Moyo Utara District, have not implemented good feeding management for beef cattle and concentrated feed for livestock. This is due to the lack of knowledge and understanding of the community about good management of maintenance and feeding of beef cattle.
