Abstract

Class furniture, namely tables and chairs, are significant physical facilities because the furniture is used for teaching and learning activities. Pain in the neck, waist, right upper arm, right forearm and right wrist during the learning process due to non-ergonomic facilities. Therefore, this research aims to minimize the complaints of Musculoskeletal Disorder with the Ergonomic Learning Chair. In this study, descriptive research with the REBA method and the RULA method was used. With the REBA method, the final score obtained in Group C is 8, then this value is entered at Action Level 3, after which researchers can only find out that the student's body posture level is in the High category so that action is needed immediately. With the RULA method, the student's body activity results are at a Group C score of 7. The value is entered for Action Level 4 so that the student's posture is in the dangerous category for safety, health and comfort. Therefore, action is needed now to overcome this problem with the suggestion manufacture of Ergonomic Study Chair. From the results of the chair use test design analysis by distributing questionnaires to 35 students as a sample, it was found that there was a decrease in complaints of Musculoskeletal Disorder in the student body. With the contribution of the study table, it can be adjusted up and down (adjustable) to make the chair more comfortable.

Abstract

Product packaging is one of the critical factors in a product. The main problem with product packaging is the frequent occurrence of defects that exceed the company's targets and cause consumer disappointment. The purpose of this research is to minimise the occurrence of defects in product packaging so that recommendations for improvement and performance control mechanisms are needed. Improvement recommendations are made based on analysing the failure mode using the Pareto chart and FMEA (failure mode and effect analysis) tools. The results of this study are in the form of SOP recommendations for improvement and control mechanisms for 3 product packaging.

Abstract

National High School Malang is one of the best private schools with a myriad of achievements. In 2019, National High SchoolMalang was honored as one of Indonesia's best private schools by the Minister of Education and Culture. National High School Malang is one of the private schools in Malang City that has also been affected by the Covid-19 pandemic. The Covid-19 pandemic has not really ended and life must go on. The Covid-19 pandemic has indirectly changed labor patterns both in the scope of government, agencies, private sector, and others. This research aims to design a model for determining the criteria for providing performance-based incentives to teachers at National High SchoolMalang to improve service quality after the Covid-19 pandemic. In this study, the calculation results are used to determine the amount of incentive proposals that will be obtained by each teacher by taking into account the results of the performance assessment. Based on the results of the calculation of the proposed incentives, it can be concluded that there was an increase in the average incentive for each teacher by 35%. This shows that with an increase in incentives it is expected that there will be an increase in the value of work performance. And in line with the results of the calculation of the proposed incentive increase, it was found that there was also an increase in work performance of 51%. With this, it can be concluded that the provision of incentives has a major effect on increasing work performance.

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.
