Abstract

Tatti Crochet is an MSME (Micro, Small, and Medium Enterprise) in Malang City engaged in the handicraft industry. The handicrafts produced are knitted goods, with a specialisation in knitting bags. As an MSME producing handicrafts, Tatti Crochet faces problems in human resources, especially knitters. The number of knitters currently available is three people, and this number cannot support the production needs of Tatti Crochet. This is one of the risks that must be faced not only by MSMEs but also by other organisations and companies. Risk management can be carried out by risk identification, evaluation and measurement, and risk management. One method that can be used to manage risk is the House of Risk. From the risk identification process, Tatti Crochet faced 22 risk events triggered by 29 agents. Based on the calculation of HOR Phase 1, 10 risk agents will enter HOR Phase 2 for determining preventive action, namely A11, A10, A18, A13, A14, A3, A12, A5, A28, and A4. Finally, one preventative measure was soon done with the highest ETD number, PA1, with ETD 1620.

Abstract

In the context of an organisation/company or business, operational scope is very important, including all risks. PT XYZ continues to demonstrate performance metrics with a compliance rate of less than 100% in the conduct of its business and is considered a risk in the Company's operational framework. Therefore, the purpose of this research is to propose improvement or control solutions to reduce operational risk and recommend the risk management ISO 31000 version of treatment. In principle, 2 (two) calculation steps were performed in this study, namely before and after providing repair solutions. The methods used are Failure Modes and Effects Analysis (FMEA) and risk matrix, Pareto charts are used to rank risks from highest to lowest, and fishbone diagrams to analyze repair solutions. As a result, the total risk score becomes R8 = 2.40 to 1.60, followed by a decrease from R2 = 0.96 to 0.16, R1 = 0.36 to 0.24, R6 = 0.108 to 0.03, R7 = 0.108 to 0.03, R4 = 0.096 to 0.02, R3 = 0.06 to 0.02 and R5 = 0.036 to 0.02. From the categorization of the risk matrix there is then also a decrease in impact which originally had 5 (five) low risk categories to 6 (six) risks, then 1 (one) medium risk and the remaining 1 (one) extreme risk. In accordance with ISO 31000:2018 risk management recommendations that risk before control, namely accepting risk is applied to 5 (five) risks, risk mitigation is applied to 1 (one) risk, avoiding risk is applied to 2 (two) risks. Risk after control, namely accepting risk is applied to 6 (six) risks, risk mitigation is applied to 1 (one) risk and risk avoidance is applied to 1 (one) risk.

Abstract

PT. ABC is a paint manufacturing company that has been established since 1978. The products it produces are various types of paint, both water based and solvent based. Inside PT. ABC has a Metal Production Department whose job is to make paint packaging cans, because PT. ABC makes cans for packaging its paint products independently. One of the work stations that play an important role in the continuity of the production process in the Metal Production Department is the component manufacturing work station. At the work station, the process of making components is carried out using a press machine, namely by carrying out the blanking / punching process on tinplate sheets according to the size needed. Data for 12 months shows maintenance activities that are not optimal and cause high downtime because the machine is damaged, this study aims to find out how much the performance of the machine is using the Equipment Effectiveness (OEE) method as well as the loss of machines that are damaged and reduce very high down time by implementing strategies scheduling of set up intervals on ring sheet press machines with the Reliability Centered Maintenance (RCM) method. The OEE calculation results show an effectiveness value of 77.22%. There are components that are still not good and are below world class standards, namely availability of 79.81% of the standard limit of 90%. And from the results of the six big losses analysis, it is obtained that the losses that are dominant to the low availability value are set up and adjustment with a losses percentage of 10.34%. Factors that affect the high set up and adjustment time are found through fishbone diagrams. RCM analysis is performed to calculate the set up and adjustment time intervals and then make a set up and adjustment time scheduling plan. As well as given suggestions for improvements given through humans, machines, materials, methods, and the environment it is hoped that the effectiveness of the ring sheet press 1 machine can increase.

Abstract

This study investigated the effect of the coffee drying process using a coffee drying house on the moisture content, acidity, caffeine value, and flavour of Arabica coffee. An experimental method with a two-factor analysis of variance was used to evaluate significant differences between three different drying processes: Before Drying Process, Sun Drying Process, and Drying Process with Coffee Drying House. The results showed that sun-drying coffee with a coffee drying house produced lower moisture content, acidity, and caffeine value than the other drying processes. The flavour of Arabica coffee produced by this method was also considered sweeter by coffee export standards. Statistical analysis with Anova Block Subsampling, Anova 1 Factor Fixed Model, and Anova 2 Factor Factorial Design showed that the coffee drying process using coffee drying houses significantly affects the quality of arabica coffee. This study concludes that coffee drying houses can be an effective solution in improving the quality of Arabica coffee by controlling the moisture content, acidity, and caffeine value. The results of this study contribute to understanding the process of drying coffee beans and the factors that affect the final quality of the product. Therefore, this study provides an essential scientific basis for coffee farmers and the coffee processing industry to improve the quality of their coffee.
