Abstract

The distribution of soybean raw materials is not only related to aspects of quality and smooth production of tofu making but can also influence cost efficiency to increase competitiveness. In this situation, the number of soybeans shipped, transportation costs per unit, and the choice of transportation service used are transportation model issues. This research aims to determine the cheapest cost of sending soybean raw materials from four agent locations to three tofu factory locations with a choice of two transportation services that can be adopted. The case studied is a case of unbalanced transportation with supply greater than demand. The method used is the application of a transportation model, with the Northwest Corner method to determine the initial base solution and the Modified Distribution method to optimize distribution costs for soybean raw materials in the context of tofu production supply. Based on data processing, the results showed that the first and second transportation services offered services with a total shipping cost of IDR 691,750 and IDR 605,250. Observation of these differences leads to the conclusion that the second transportation service offers the most optimal value for money. The research results provide additional knowledge for tofu makers in optimizing costs and delivery routes for soybean raw materials, supporting production continuity, and increasing competitiveness in an ever-changing market.

Abstract

Global warming has become a major concern due to its impacts on the environment and human life. One way to reduce these impacts is by increasing the use of renewable energy. Introducing the concept of renewable energy at the elementary school level is expected to foster students’ awareness and understanding of the importance of using clean energy. This Community Service (PkM) program aims to enhance the knowledge and understanding of students and teachers at SD Islam Al Azhar 5, West Jakarta, regarding solar-based renewable energy through an interactive learning approach. The activities were carried out in several stages, including survey, socialization, training, evaluation, and sustainability. The socialization session was delivered through material presentations supported by engaging visual media, while the training involved assembling toys powered by solar energy. The results showed strong enthusiasm, improved understanding of renewable energy among students and teachers, and enhanced teacher skills in implementing interactive learning. This program also encouraged greater awareness of the importance of adopting renewable energy in daily life.
