Abstract

The food supply chain in West Nusa Tenggara (NTB) faces several challenges, including poor transportation infrastructure, high distribution costs, and post-harvest losses. This study aims to design a mathematical model based on Linear Programming (LP) to improve the efficiency of the food supply chain in the region. The findings reveal that investments in transportation infrastructure, post-harvest technology, and technology-based information systems can significantly reduce distribution costs by 15%, decrease post-harvest losses by 25%, and enhance price stability. This model provides practical solutions to optimize food distribution and supports sustainable food security policies.

Abstract

Pengadangan Village, Pringgasela District, East Lombok Regency, West Nusa Tenggara Province has a superior commodity in the form of bananas. Despite having great potential, the banana sale industry in Pengadangan Village faces various challenges that hinder the development and improvement of product quality, including the process of drying banana sales is still highly dependent on sunlight, the packaging of banana sale products is still relatively simple and marketing problems that are currently still conventionally sold in the market and in stalls. The application of solar energy-based hybrid drying technology that is more efficient and environmentally friendly is a solution for Bale Sentosa MSMEs in overcoming the problem of the drying process in making banana sales. So far, MSME owners have carried out a traditional drying process where bananas are sold in the open in the open in direct sunlight. This condition causes banana sales to be easily contaminated by animals such as flies and dust. The service team provides solar energy-based hybrid system drying technology to improve the quality of banana sale products. The next process is the packaging of banana sale using paper standing pouch packaging equipped with brand labels. The owner of Bale Sentosa MSMEs is very happy and satisfied with the existence of solar energy-based hybrid drying because in addition to being very useful in overcoming the shortcomings of conventional method drying, the owner of Bale Sentosa MSMEs also gains an understanding of simple technology in drying using hybrid-based drying solar energy. In addition, the introduction of packaging is felt to be very useful because by providing information on packaging and by using modern packaging, the market can be expanded, not only in the surrounding area.
