Through MS, we can imitate and project the real state of a method to get information about the time of manufacture. Our research focuses on modelling and simulation with Discrete Event Simulation (DES) and Agent-Based Simulation (ABS) using AnyLogic Software to provide information related to the pesticide production process at PT DAI. The results of this study provide an overview of the production process in 2D with some information such as processing time, machine idle time, and overall system utilization. Processing percentage values obtained from nine work stations in the range 89.93% -99.99% and overall system utilization with a value of 0.94.

In the industrial world, quality control is essential to meet customer demand. The problem formulated in this study is the assessment of the Defect of the Cutter Case produced by PT. The object in this study is the Cutter Case product. The number of samples used was 450 units. The Cutter Case will be inspected for the number of defective products and defect criteria that are met for each product unit, and the length and width of the product surface. Rules for the type of defect studied were melting, non-jagging, and bent. The method used in solving problems in this study is the Six Sigma method, namely DMAIC (Define, Measure, Analyse, Improve, Control).

Clothing products are also known as the time changing industry, which is an industry that must continue to innovate to meet consumer desires. Berastagi clothing products are one of the typical souvenirs of the Berastagi tourism area. Based on a preliminary survey conducted on 84 tourists, 70.24 percent stated that the dress design was not attractive. As many as 70 percent of the tourists state that the design of these clothes is outdated. Therefore it is necessary to design new clothes designs. The method used in this study is kansei engineering to identify the kansei, items, and product categories that are consumer’s preferences. In this study, four questionnaires were used. The first questionnaire is an open questionnaire that is used to analyze the product word kansei. The results are obtained in the form of nineteen kansei words which will be used as input to the second questionnaire. Each kansei...

Tropical fruits as agricultural products have a large number of consumers in North Sumatra. The number of sales of tropical fruit is strongly influenced by selling price. The flow of this product from farm to consumer involves supplier, consumer, and producer supply chain subsystem. This study begins by expanding the main model of the tropical fruit's supply chain and come across the matter variables. Anylogic software is being used for the method analysis and applied by modeling and simulation of the tropical fruit supply chain. The results indicate that the supply chain of tropical fruit in North Sumatra is cross-sectoral due to it is relative to some consecutive relation.

If the product not delivered at the right time, the quality of the product will decrease. Due to this situation, the optimization of the logistics process is an essential aspect of operations in the supply chain system of durian. To estimate how long the product will arrive to the consumer can be obtained by performing a real system simulation and a software-based digital system. With the help of AnyLogic software, we model logistics process optimization based on discrete systems and agent-based Geographic Information System (GIS) simulations. The simulation produces a visualization of a real process model of the durian supply chain logistics, order time estimation, and supplier utility in durian distribution in North Sumatra province. Estimating model shows the estimated time of the order from the farm to the distributor location in Berastagi of 2.43 hours, Padang Bulan...

This supply chain system must be analyzed deeply to get the optimum value to solve problem that have occurred so far related with economic, social and environmental aspect. This research begins by developing the primary model of supply chain of durian and find the problem variables. Then the system analysis is done through modeling and simulation of durian supply chains using anylogic software. The results show that the durian industrial system in North Sumatra is cross-sectoral because it is related to several related relationships. Optimization is carried out with a supply chain behavior prediction system in the next 10 years seen from social, economic, and environmental aspects. After increasing productivity from 0.72% by 1.69%, the use of chemical-based fertilizers is 104.952 tons / year in the following 10 years. In addition to the economic aspect, the increase in farmer profits to Rp. 2,475,010,917, -, adding labor to 250,340 people / year.
