Abstract

The most widely generated waste is organic waste, which is 60% compared to other types of waste. So far, NRC has been able to process organic waste to be used as animal feed products for catfish or pellets. The production capacity that can be carried out by the NRC company is 150 kg to 200 kg per day, but the organic waste obtained at this time has not been able to reach the required production capacity. Based on this, it is necessary to propose a better organic waste supply chain model for NRC companies. The purpose of this study will be to map the supply chain of organic waste into catfish feed. The supply chain model made is the current supply chain and the proposed supply chain. The final output of the study will compare current conditions and proposed supply chain models. The simulation results with arena software show the acquisition of organic waste as much as 352 kg. That means organic waste obtained by the NRC company from the 4 waste banks is 352 kg. Recommended supply chain recommendations have 4 waste bank suppliers, with each bank having a minimum of 3 waste producers.

Abstract

The effort to preserve batik is to maintain the continuity of batik production. Coloring process is one of the important processes in batik production. In addition to the dyeing technique, there is a “colet” technique in batik coloring process. Colet technique is considered an efficient technique in saving coloring dyes. The colet process is still carried out without standards and does not consider ergonomic aspects. This study aims to analyze the risk level of batik workers posture in colet technique coloring process. This research is an observational study with data analysis using the Rapid Entire Body Assessment (REBA) and Nordic Body Map (NBM). Based on the measurement, the risk level with the initial work posture has a score 9 and 7, which means the posture needs immediate corrective action to prevent occupational diseases. The implementation of Ergonomic “Colet” workbench is a way to improve work posture so the risk could be decreased, with score 4 both in standing and sitting working position.
