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.

Abstract

This study was conducted at PT. XYZ to evaluate and reduce the risk of musculoskeletal disorders among host streamers through the design of ergonomic workstations. The research method used was a quantitative case study approach, with the population consisting of employees at PT. XYZ who worked as host streamers. Primary data were collected through observation, questionnaires, guidelines, and interviews. Posture measurements were taken using the REBA (Rapid Entire Body Assessment) and RULA (Rapid Upper Limb Assessment) methods. The results indicated that prior to the intervention, host streamers had REBA and RULA scores that signified a high risk of musculoskeletal disorders, particularly in the neck, shoulders, back, and legs. After implementing an adjustable live streaming workstation design, along with adjustments to lighting and microphone positions, there was a significant decrease in the REBA and RULA scores. The REBA score decreased from 10 to 1, and the average RULA score dropped from 7 to 3. This indicated a significant reduction in the risk of musculoskeletal disorders. This indicates a significant reduction in the risk of musculoskeletal disorders. Thus, designing an adjustable ergonomic workbench significantly reduces the risk of musculoskeletal disorders in host streamers at PT XYZ and improves worker comfort.

Abstract

A key duplicate machine is indispensable for daily needs. There are so many functions that we can get by having a key machine. One example is that we can duplicate the keys we have everyday, whether house keys, car keys, motorcycle keys, or so on. The method applied in the design of this key duplicate machine construction begins with concept design, presentation of drawings, and identification of tools and materials used in the design of the key duplicate machine construction consisting of 2 types of machines, namely: DEFU 339C and DEFU 238BS. This key duplicate machine is designed to help residents duplicate the keys of both tools and vehicles so that they are not hampered when doing activities and become more efficient because the process of making duplicate keys uses tools designed by showing aspects of cost, efficiency, and effectiveness. This tool uses a power source from an electric motor with a minimalist construction design but with a relatively cheap tool production cost with similar products sold in the market. The process starts from selecting the type of key material, then the key material is recorded on a duplicate machine along with the parent key with the same shape so that it is precise and functions properly.

Abstract

Malang City, apart from being a city of education, has also developed small industries to support the development of the city. Rice is one of Indonesia's products, especially for the Indonesian people themselves. Because the staple food of Indonesian people is rice. So many rice farmers in Sukun Subdistrict, Malang City, especially in the Bandungrejosari area. The main obstacle faced by farmers is that in addition to limited capital, they also do not have adequate production support equipment. The process of threshing rice seeds is done traditionally using human labor so that the production process takes a very long time. This constraint causes low productivity of rice grains. With this argument, it is necessary to make a rice thresher machine that can improve the quality of production. This activity aims to apply Engineering Technology, this is the development of appropriate technology equipment to utilize the power of the rice thresher machine, the threshing process is faster and maximum to increase the efficiency of production time. With the application of the use of the developed rice thresher machine, it is hoped that it can help the MSME industry in running its business properly and profitably. The impact obtained from this activity is that this tool from an economic point of view is expected to have an impact on increasing income as a consequence of increasing production capacity. With the increase in production capacity, the demand for this commodity from rice farmers will also increase so that it can indirectly increase the income of the farmers themselves.
