Abstract

Machines are an important factor in the industrial world to produce a product in a company. PT. XYZ is a company engaged in the food industry for sweeteners processed from tapioca flour and corn flour where, through research observations, data is obtained that there are problems that are often faced such as damage to the Agitator Autoclave machine, unavailability of spare parts ( spare parts) needed when there is a breakdown and a breakdown schedule for maintenance workers who have to work overtime. The purpose of this study is to determine the current condition of machine maintenance to reduce damage or failures, the level of machine effectiveness and provide alternative solutions to increase machine effectiveness. The research method used is quantitative using the Overall Equipment Effectiveness (OEE) method, Six Big Losses, Failure Modes and Effects Analysis. The results of the study resulted in an Overall Equipment Effectiveness (OEE) value of 75.07%. The low OEE value on the Agitator Autoclave machine is due to the low performance factor because the engine speed does not match its ideal speed and also the low idle and minor losses in the losses factor caused by frequent breakdowns. Suggestions and suggestions that can be recommended are to periodically evaluate machines and replace old machines.

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

To prepare civil servants who are professional, capable of competing, and capable of anticipating rapid world developments in various aspects of life, in order to improve service quality and awareness of the need for quality human resources, various strategies that can improve employee performance must be implemented. One strategy is to provide additional employee income as a form of motivation (TPP). The goal of this study is to assess community satisfaction with the performance of the Central Sumba Regency's cooperative, SME, industry, and trade departments using Voice of Customer data. The research method employs questionnaires to assess customer satisfaction with the PDCA approach, as well as service quality and IPA analysis. The findings of this study indicate that people are dissatisfied with the performance of employees and that changes must be made. The final results obtained after using the PDCA approach and analysis using servqual and Importance Performance Analysis (IPA) are performance factors that are priority improvements and performance that must be maintained in order to meet community satisfaction.

Abstract

The oil and gas industry is a workplace with many sources of danger, such as gas pressure, explosions, fire, electricity, moving equipment, and transportation. Field observations often result in work being stopped due to findings regarding unsafe conditions and unsafe actions in the workplace. Efforts can be made to protect workers' occupational health and safety by creating a safe climate in the workplace. This research aims to provide improvement solutions based on the safety climate factors that are most important in improving occupational health and safety in construction work. This research uses quantitative research methods. The research was conducted at the PT XYZ Bunyu fieldwork area in Bulungan Regency, North Kalimantan Province. The population used was all construction work employees under the supervision of the operation & surface facilities construction department, totalling 200 workers, while the sample was 180 workers. This research uses the Exploratory Factor Analysis method. The safety climate factor analysis results show that the total variance is 86.538%. Four factors were produced: training and compliance for occupational health and safety at 60.58%, leadership, knowledge, and attitude of workers at 15.392%, management commitment and worker initiative at 6.313%, and safety campaign at 4.248%. Implementing the proposed improvements uses one factor, a safety campaign, where observations indicate that field implementation has been carried out well. This research does not analyse the relationship between the influence of safety climate factors on occupational health and safety; the suggestions for further research include examining the relationship between the influence of safety climate factors on occupational health and safety to find out the technical aspects and to apply existing factors directly in the field.

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.
