Abstract

The process of planting corn using conventional methods that have been happening in the community so far has become a problem faced by partners. As a result, the corn planting process takes a long time due to the stages of land preparation, seed placement, and corn covering not occurring simultaneously. By providing training and direct assistance to partners on the use of corn seed planting tools, it can improve their understanding and skills in using the tool effectively. By conducting socialization methods to provide understanding to partners with the aim of the community understanding the use of corn seed planting tools based on the double seed hopper and understanding how to maintain the tool. Thus, with this tool, the corn seed planting process becomes faster. Corn planting is the most widely produced crop in the world, and corn seed plants are most suitable for planting in high-temperature areas. Especially in Indonesia, corn plants cover more than 100 million hectares, consisting of 70 countries and even 53 developing countries. The tool being socialized is a simple tool that is used with human power by pushing without the use of motorized equipment. In the planting process, the spacing between corn seed plants and the number of corn seeds can be adjusted during the planting process. The vessel or container supplying corn seeds is a hopper located at the top, and a hole is provided at the bottom of the hopper, which is the outlet channel. Thus, the results of this socialization can shorten the time in the corn seed planting process. Keywords : corn seed; produktif; corn seed planting tool; hopper; maintenance

Abstract

Historically, cloves were one of the main spices that drove international trade routes and the arrival of Europeans to the Indonesian archipelago. Cloves remain a crucial commodity today, particularly for the clove cigarette, pharmaceutical, food, beverage, and essential oil industries. Drying cloves is a crucial stage in the post-harvest process, aimed at reducing water content and improving product quality. This clove drying machine socialization aims to accelerate clove production in Buttu Bartong village, addressing the energy needs of clove drying machines with various heating elements: electric, gas, and biomass heaters. The method used is socialization of clove drying machines with various heating elements to accelerate clove harvest production in Buttu Bartong village. Electric heaters provide more stable temperature control, while gas heaters show lower operational costs. This socialization is expected to provide recommendations regarding optimal drying systems, which are not only energy efficient but also economical, thus supporting the sustainability of optimal clove processing production.

Abstract

This report presents the results of a field observation on the strategic role of the prebreaker machine in improving the quality of crumb rubber of the Standard Indonesian Rubber 20 (SIR 20) type at PT Bridgestone Sumatra Rubber Estate. The background of this observation is based on the complexity of processing raw rubber materials (Bokar), which are often contaminated by organic and inorganic materials that can reduce the physical integrity of tire products. The main objective of the observation is to evaluate the mechanical effectiveness of the prebreaker machine in reducing material size, improving contaminant removal efficiency, and preparing the rubber structure for optimal drying stages. The methods applied include participatory observation on the wet processing line, technical sampling, and comparative analysis of quality control laboratory data during the fieldwork practice period. The results indicate that the use of the prebreaker machine significantly reduces dirt content to below the threshold of 0.16% in accordance with SNI 1903:2011 standards and minimizes the formation of white spot defects through improved crumb homogeneity. The conclusion of this study confirms that optimizing blade configuration and rotational speed of the prebreaker machine is a key determinant in producing raw rubber that meets the technical specifications of the global automotive industry, while also supporting energy efficiency in subsequent production stages.

Abstract

The Community Service Program (KPPM) that has been implemented has had a positive impact on the community, particularly in raising awareness about the importance of maintaining environmental cleanliness. Through this program, the people of Pardomuan Village—especially the youth—have gained a deeper understanding of the importance of keeping the environment clean as an integral part of daily life. As a result of this activity, the community has become more active in mutual cooperation and in working together with the local government to create a waste-free environment. Considering that environmental cleanliness is both a right and a shared necessity in maintaining a healthy environment, it is hoped that similar activities can be carried out sustainably to provide long-term benefits for both the local community and visiting tourists.

Abstract

Processing leaves to make compost is generally still done by chopping using a machete, or many are not chopped, making it difficult for the leaves to decompose or rot. This research aims to determine the results of chopping using a single blade and by varying the size of the blade and varying the rotation speed of the machine. The benefit of this research is to determine the influence of leaf chopper machine components, especially the number of leaf chopper blades, using descriptive qualitative research methods with data collection methods, literature studies and observations. The research location is in the HKBP Nommensen University Laboratory workshop, Pematang Siantar, North Sumatra. The research process took the form of testing carried out in several stages, namely using a single blade by varying the length of the blade and varying the rotation speed of the machine to compare the speed and chopping results. Three trials were carried out each with varying blade lengths of 30cm, 35cm and 40cm and rotation variations of 2500rpm, 3000rpm and 5000rpm. The results are in the form of a comparison of speed and counting results between variations of 30cm, 35cm and 40cm. The test results more effectively lead to variations in blade size of 40cm. And the results of testing the engine rotation speed which is more effective leads to a rotation speed variation of 5000rpm.

Abstract

Onan Lama Village has abundant natural resources in the form of sugar palm (aren), yet its utilization remains limited to traditional products with relatively low added value. The main problems faced by the community include a lack of knowledge regarding product diversification and limited processing technology, particularly in the peeling process, which is still carried out manually, making it inefficient and time-consuming. This Community Service Program aims to improve community knowledge and skills through counseling on sugar palm product diversification and the application of a modern sugar palm peeling machine. The methods employed in this program include socialization, training on machine operation, and direct assistance to community groups. The activities were also complemented by demonstrations of processing sugar palm into various value-added products, such as palm sugar, kolang-kaling, and other derivative products. The results indicate an increase in community understanding of the potential for sugar palm product diversification, as well as improved work efficiency through the use of a modern peeling machine, which accelerates the processing time and reduces labor intensity. This program is expected to enable the community of Onan Lama Village to develop sugar palm-based enterprises more optimally, increase the economic value of their products, and promote community economic independence. Furthermore, the implementation of this appropriate technology is expected to be sustainable and serve as a development model for other regions with similar potential.
