Abstract

Hygiene and product safety were the main issue that need to be assured by food industries, including amplang industries in Samarinda. Furthermore, workers safety was also important for improving small industries’ productivity. This paper aimed to evaluate application of Good Manufacturing Practise (GMP) and Work Improvements in Small Medium Entreprise (WISE) in two small industries that produce amplang. GMP is a system that ensures products are consistently produced and controlled according to set quality standards. (i.e., BPOM standard). WISE is a programme to assist micro, small and medium-sized enterprises improve working conditions and productivity using simple, effective and affordable techniques. The GMP study showed that SME Y had GMP value higher than SME X (i68% and 55%). These two SMEs have used clean water to produce amplang and store raw materials, end products and hazardous materials properly. The drawbacks of these two SMEs are the need to improve recording and documentation as well as make SOPs for product withdrawals from the market. UKM X needs to make SOPs for the cleanliness of the production area and improve product labels. The results of the WISE study of these two SMEs have not provided appropriate PPE for workers and have not promoted occupational health. Procedure for mitigating fire hazard had not developed although fire was one of the risk factors in these two SMEs. Evacuation path had not been provided and even, SME X had not provided the fire extinguishers. Furthermore, ergonomic work station obliged to design especially for workers who sit cross-legged, designing cross-legged chair with back rest.

Abstract

Most of the technology from universities (PT) related to technological innovation often fails to enter the market. This problem then becomes the basis and object of improvement in technology-based entrepreneurial practices (technopreneurs). Learning is carried out through Independence Learning Campus Independence (MBKM) which converts courses according to training subjects in collaboration with PUI UNS and BPPT. This practice is a model of participatory and collaborative learning, in which students are directly involved in solving existing case studies and act as perpetrators of technology commercialization and become technopreneurs. Students are initially given training materials in accordance with the curriculum and direct learning from existing tenants. As a result, through this learning process, students can design business process proposals that exist in tenants. The success of this learning method was assessed based on technopreneur analysis from students in answering problems faced by tenants based on aspects of product technology innovation, product development, business development, and its implementation at BMC. One of the tenants who is the object of the case study in this study is the start-up PT. EKM who have problems with the commercialization of technology in the case of konverter kit products.

Abstract

CV Tirta Alam Dodu is a privately owned company engaged in the beverage industry in the form of AMDK. The problem faced by the company is that there is a difference between demand and sales, or better known as the bullwhip effect problem. The purpose of this study is to reduce the bullwhip effect on the supply chain and optimize the amount of product inventory according to the amount of demand. The method used is the Collaborative Planning, Forecasting, and Replenishment (CPFR) method. Based on the results of the research conducted, it can be concluded that the analysis of demand forecasting calculations on AMDK products at CV Tirta Alam Dodu was carried out using historical data on product demand through five analytical methods, including Linear Trend, Moving Average, Exponential Smoothing, Decomposition, and Winter's Model. The best forecasting resulted in Winter's Model which showed the smallest error value compared to the other four models. The way to minimize so that it does not become a bullwhip effect is to use the CPFR method, where the bullwhip effect value is obtained on glass mineral water products and gallons of mineral water of 0,985 and 0,898, respectively. This result shows that there is no amplification of demand and has reached the company's target, which is to fall below number one. The way to optimize inventory so that there is no excess stock or shortage of stock in the product is to make the amount of inventory based on the amount of demand from the forecasting results plus the safety stock.

Abstract

Nowadays, competition among manufaktur industries is increasing rapidly. This competition causes similar industries to compete, including the automotive component industry. To win the competition, the automotive component manufaktur industry must carry out various repair methods. Improvements made include managing inventory, scheduling, delivery, quality management and eliminating waste. Based on observations, problems that often occur in the automotive component manufaktur industry are not achieving production output and unbalanced production lines so that problems such as waste and bootleneck arise. The purpose of this research is to design a model on the production line to increase production output and balance the production line. The method used to analyze and solve this problem is to design a conceptual model of Theory of Constraints (ToC). This method interprets structured and systematic stages to solve problems in the manufaktur industry. Based on the analysis, the results of this study produce a generic model that can be used in the automotive component industry. The models offered can increase production output, balance workloads and eliminate waste.
