Abstract

Opak Desi UKM is an UKM engaged in producing opaque crackers made from sweet potatoes/cassava. However, the work environment in these SMEs still does not have a clean kitchen standard. This clean kitchen standard is known as the GMP rules (Good Manufacturing Practice). GMP is a guideline for how to produce food with the aim that producers meet the predetermined requirements to produce quality food products in accordance with consumer demands. The problem is that the production area in SMEs is less hygienic and uncomfortable for workers and the flow of materials that occur experience cross movement, which means they intersect and also occur double tracking which causes the production process to be hampered. This research was completed using the assessment of the GMP checklist to evaluate the overall work system. The results of the checklist assessment are processed using the AHP method. The results of the assessment show that the criteria for storage and material handling with a weight of 1.65658 for UKM Opak are work system improvement priorities. Some of the proposed recommendations for improving the work system are the design of the SSOP work system, GMP, and the design of a new layout adapted to food safety and hygiene standards. The recommendations are expected to be able to increase productivity in the production process as well as safer, healthier and more comfortable working conditions.

Abstract

PT. Toba Pulp Lestari, Tbk is a company engaged in the pulp and kerta production business with domestic and foreign product marketing areas. PT. Toba Pulp Lestari, Tbk is one of Indonesia's largest pulp and paper producing companies. The purpose of this study is to determine the ability of the process based on existing off-grade products using the Failure Mode and Effect Analysis and Fault Tree Analysis methods to then control and analyze the causes of off-grade products and seek improvements. The results showed that there were 3 types of off-grade products: Low Brightness, Dirt Count, and Viscosity. From the calculation, the results were obtained that the largest off-grade products were X1 (viscosity) with a number of smallpox products as much as 167 tons with 26.95%, X2 (brightness) with a number of defective products with as much as 332 tons with 53.55%, and X3 (dirt count) with the number of defective products as much as 124 tons with 20%. From the FMEA results, the highest Risk Priority Number (RPN) value was obtained, namely 432 for the cause of failure due to irregular setting of the temperature and time of the digester and washing machine at Low Brightness failure. For continuous improvement, various aspects are carried out, namely human aspects, work environment, work methods, machines, and, materials.
