Abstract

Yoghurt is a pro-biotic beverage produced from the fermentation process of milk, namely from vegetable milk (soy milk) or animal milk (goat's milk and cow's milk). During the fermentation process, the chemical reactions that occur will turn milk into yogurt with the help of lactic acid bacteria. In the health sector, yogurt plays a role in increasing the body's immunity, digestive tract health and can prevent osteoporosis. In general, yogurt circulating in the community still has low nutritional content, so a more in-depth study needs to be done. The goal of this research is to examine the quality of yogurt by manipulating certain variables and adding other components to increase the yogurt's quality. Streptococcus thermophilus and Lactobacillus bulgaricus were used as starter as much as 12.5 mL each (10% of 500 mL of cream milk). The fixed variables in this study were the volume of goat's milk 500 ml, cream concentration 6%, pasteurization temperature 85°C, pasteurization time 15 minutes and fermentation temperature 45°C, while the independent variables were varying the length of the fermentation process for 3, 4, 5, 6, 7, 8 and 9 hours. From this study, it was concluded that yogurt with optimum results was obtained at a fermentation time of 6 hours, the pH value was 3.8, lactic acid content was 1.305%, protein content was 5.54%, fat content was 4.98%, and moisture content was 84.10%.

Abstract

UD. Teungku Aceh Coffee is a business engaged in coffee production. In the November 2020-October 2021 period, this business has not been able to achieve the predetermined production target, which is 300 kg per day and 7,000 kg per month. The purpose of this study was to measure partial productivity in the production process using the Objective Matrix (OMAX) method. The second objective is to provide recommendations for improvement of the ratio that causes a decrease in productivity based on fault tree analysis (FTA). The criteria measured are the use of raw materials, labor hours, production line workers, machine working hours and electrical energy consumption. Based on the results of the OMAX calculation, the lowest ratio score is the ratio 1, which means that it causes a decrease in productivity in the UD production process. Kopi Teungku Aceh is ratio 1. Recommendations for improvement are given to increase productivity in ratio 1, namely, forming an inspection section as a raw material inspection division by making an analysis report (LA) as evidence that raw material inspection has been carried out, making a firewood storage area in the factory yard that is empty, performs a mixed drying process between natural and automatic drying and ensures the availability of suppliers in the timely delivery of raw materials.

Abstract

PT Ravana Jaya is a company implementing construction services and steel plate fabrication. As for the activities of the steel plate fabrication process, labor makes direct contact with work activities that have a high risk of work accidents and are dangerous. Based on work accident report data from 2019 to 2021, the majority of work accidents occur in grinding activities caused by work conditions, operator experience and human error. The purpose of the study is to identify and analyze the factors of accidents that occur caused by human error using the CREAM method. The CREAM method is a method of analyzing human constraints that measures cognitive reliability and possible errors. The results showed that the cognitive function with the highest error value was found in the interpretation perspective of diagnosing inaccurate or incomplete data with a CFP value of 0.024 contained in Task 4.2 in the error mode ensuring the quality of the grinding stone in good condition and not cracked, Task 4.3 in the mode of ensuring that the rpm of the grinding stone is greater than the rpm of the grinding machine and Task 5.1 in the mode of checking the work area neatly before activities.

Abstract

LCA is a method for evaluating the potential environmental effect of a product or service system at all stages of its life cycle by quantifying resource usage and emissions connected with the system under consideration. This paper intends to give an overview of the numerous Life Cycle Assessment (LCA) studies that have been implemented in Indonesian industries in order to reduce the negative effects of pollution on the environment, low distribution, and energy and raw material conservation. In the Life Cycle Assessment (LCA), there are four system boundaries: (cradle to grave), (cradle to gate), (gate to grave), and (gate to grave) (Gate to gate). The scope of this study is restricted to a review of the literature on the application of Life Cycle Assessment from 2018 to 2021, it was published in peer-reviewed journals. There are 11 research publications on the internet with the keywords Life Cycle Assessment (LCA) regarding Life Cycle Assessment (LCA) in Indonesia, which is used to reduce environmental effect in industry. Waste management products, water management, manufacturing industry, mining, fisheries, and plantations are among the research journals covered.

Abstract The fast advancement of the business makes organizations are expected to keep on being useful with great quality. In this manner, the organization should have the option to keep up with each component connected with creation including machines. As one of the primary parts of creation, machines should be kept up with so their efficiency abilities are kept up with and work runs successfully. This study meant to break down the adequacy of welding machine execution through Total Productive Maintenance (TPM) at PT. Otson Safety Indonesia. The technique utilized is Overall Equipment Effectiveness (OEE) with three estimation pointers, in particular accessibility, execution proficiency, and nature of item. The examination was done in the period June-December 2021 which comprised of information on the quantity of creation, deficient items, margin time, and arranged free time. The outcomes got are the typical OEE worth of 58.07 with a piece of 96.56% accessible rate, 89.27%% execution rate, and 95.65% quality rate. The outcomes show that the OEE esteem is still far beneath the world norm, and from the three OEE pointers just the accessible rate is in the norm, while the exhibition rate and quality rate are underneath the norm. From these outcomes, it is important to make enhancements to expand the viability of the presentation on the welding machine.Keywords: Machinery, Productivity, TPM, Manufacturing, OEE. AbstrakPesatnya kemajuan bisnis membuat organisasi diharapkan untuk terus bermanfaat dengan kualitas yang baik.
