Abstract

Utilization of wire waste is feasible to be produced as a plate basket product. The partner who has implemented this innovation is UKM Putu Alwy Jaya. The community service team conducted socialization with the topic "green logistics". This topic is in accordance with the conditions that are being experienced by partners. The purpose of this activity is to increase the role of green logistics in products made from waste wire with selling value. The implementation method includes lectures, discussions, questions and answers and evaluations. Based on the results of the aspirations of the participants involved, it was stated that it was important to recapitulate the inventory of wire waste material every time an order was made to the supplier. Then, calculate the economic order quantity as a point of ordering in the future to minimize material delays. Scheduling optimization is related to the production period. Improving the function of work tools to speed up the production process of plate baskets is the main step. Straightening tools, cutting tools and packing techniques are closely related to green logistics. Therefore, the estimated time estimate, arriving at the destination, product condition, packaging condition is an achievement in green logistics.

Abstract

This community service program aims to identify the production process of Marning Lancar Jaya SMEs, including raw materials, equipment used, and methods for managing raw material capacity. The methods employed include lectures, interactive discussions, and Q&A sessions with SME operators. The program successfully mapped and documented the entire production process, encompassing stages such as raw material selection, washing, boiling, drying, seasoning, and frying. Furthermore, the program enhanced the knowledge and skills of the partners in managing the production process more efficiently and systematically. By standardizing the process, the quality and competitiveness of corn marning products were significantly improved, creating potential opportunities to expand the market reach of Marning Lancar Jaya SMEs.

Abstract

The small and medium-scale tofu industry faces production efficiency and waste management issues that impact economic and environmental performance. This study aims to optimize yellow tofu production by maximizing profits, minimizing raw material waste, and optimizing waste utilization into economically valuable products. The Multi-Objective Linear Programming (MOLP) approach is used to model the production system by considering the limitations of raw materials, production capacity, and working hours. Fishbone Diagram analysis is applied to identify factors causing waste generation based on human, machine, material, method, environment, and management aspects. The optimization results show that the optimal production of yellow tofu reaches 1,194.03 kg/day with an objective value of Rp 7,164,179, where the constraints of working hours and the use of turmeric are in binding conditions. The integration of waste utilization allows tofu dregs to be fully utilized as a by-product of 5.01 kg/day, so that net waste can be reduced to zero. The feasibility evaluation of a circular economy using NPV, IRR, B/C, and Payback Period shows that waste utilization is financially feasible. This research contributes to the formulation of efficient, sustainable, and environmentally friendly tofu production strategies for small and medium industries.
