Abstract

Liquefied Petroleum Gas (LPG) or more commonly known as LPG gas is a gas stove fuel that comes from the results of liquefied petroleum gas and is then put into a tube, one of which is a 3-kilogram tube. The behavior of dependence on the consumption of 3-kilogram gas cylinders from the people of Banggai Regency can be seen from the use of non-subsidized 3 kilogram LPG gas, namely (±) 32. 002 people/group, the second is the consumption rate from subsidies and non-subsidies, namely 38. 864 units from total users, namely (±) 45. 000 people/groups with a supply of 30. 800 units and the third about frequent scarcity in 2020 and early 2021 reported by Banggai News and Obormotindok. Simulation Method Dynamic systems are modeling and running simulations of real systems to analyze problems and present solutions from policy scenarios from the researcher's perspective. By using this method, researchers can identify the behavior of 3 kilograms of gas consumption from the rate of consumption and demand through tables and graphs using the Powersim Studio 7 software. The results of the study present 3 policy scenarios, namely the first scenario regarding an increase in the transition to 99% non-subsidized gas cylinders with simulation results, namely September 1 2021 - October 1 2022 the demand is fulfilled, the second scenario regarding the addition of a 7th agent with simulation results, namely September 1 2021 - April 1 2023 demand can still be fulfilled and the third scenario regarding an increase in the transition to 99% non-subsidized gas cylinders and the addition of a 7th agent with simulation results, namely 1 September 2021 – 1 September 2023 the demand for needs is fulfilled. The conclusion is that the third policy scenario will be taken because among the policy scenarios presented, the preparation of tube supplies is fulfilled within two years, namely September 1 2021 - September 1 2023.

Abstract

Today's laser cutting machining process is often utilized in large industries as well as individual and student scientific projects. Acrylic is one of the materials whose processing involves a lot of laser cutting, but currently many laser cutting, especially low power ones, are not optimally optimized. In this study, the author wants to optimize laser cutting with 6.5 Watt power using the Taguchi optimization method on solid black acrylic material with a thickness of 3 mm, with reference to the surface roughness value of the workpiece after being subjected to the laser cutting process using the Ra unit. The control factors included are laser distance, laser power, cutting speed and cooling time. The experimental process was carried out 27 times with replication of measurements 2 times. The best result from the experiment was the roughness measurement value of 0.782 µm while the mean roughness value was 2.271 µm. After conducting the experiment, it is known that the best results are obtained with a laser distance factor of 20.6mm, cutting speed of 70 mm/min, laser power of 6.5 watts and cooling time of 10 s. Meanwhile, the effect of factors on the surface roughness results is the laser distance 27%, cutting speed 40.9%, laser power 18.9% and cooling time 7.05%. After calibrating the laser cutting, the cutting accuracy increased from ± 1mm to ± 0.4 mm or an increase of 60%, with an average final dimension measurement of 24.87 mm.

Abstract

In the automotive industry, after-sales service becomes one of the marketing strategies used. The obstacles arose when there was a problem with the products, but the services related follow-up decisions problem report from customers seems too long because the information delivered by the dealer has not been fulfilled. This research aims to identify waste and implement improvements that can reach the standard after-sales service time set by the company. This study uses the value stream mapping (VSM) method combined with a root cause analysis approach to reduce waste. The problem identification found that the most prolonged decision was the starting system. Then, the dominant waste is a waiting process. The VSM improved processing time efficiency by 34.47% or 33.97 hours (1.4 days). This result proved that the overall reporting time reached 60 hours (2 days) as the company target.

Abstract

Rice is the staple food with a continuous increase of it’s demand. Therefore, it’s availability should be well-maintained. Rice farmers and millers don’t yet have an advantageous position. Other risks also has the potential to disrupt the rice production process. This study aims to analyze and create priority risk mitigation in the rice supply chain of PPU. The methods used in this research were ISM to create a risk structure, FMECA to assess risk, and AHP to mitigate priority risk. There were  41 risks, consist of 26 risks for farmers and 15 risks for millers. Based on FMECA result, the priority risk from farmers is poor quality rice seeds (RPN of 112 and a medium criticality level). The priority risk from millers is damage to the rice grinder machine (RPN of 490 and a very high criticality level). The mitigation strategies were prepared by considering the interrelationships between risks in the ISM. If totaled based on the results, there were 11 risks for farmers that could be overcome by the 6 alternative mitigation strategies that exist. As for the rice mill, there were 6 risks that could be overcome by the 4 alternative mitigation strategies that exist. All of these alternatives were calculated using the AHP method. The priority mitigation for the farmer's were routine monitoring and maintaining the moisture content of the seeds, while the priority mitigation for the millers were periodic maintenance scheduling and the provision of spare engine components.
