Abstract

The world has been shocked by the emergence of COVID-19 since December 2019 which is an acute respiratory disease caused by a corona virus called severe acute respiratory syndrome coronavirus 2 or abbreviated as SARSCoV-2 (Gorbalenya et al., 2020). As of June 17, 2020, the World Health Organization (WHO) noted that there were 8,061,550 people infected with COVID-19 and 440,290 people died (WHO, 2020a). Even though the Case Fatality Rate (CFR) of COVID-19 is only around 5.46%, this disease is very dangerous because of its spread so fast it has infected 216 countries (Worldometer, 2020). To prevent uncontrolled spread, WHO declared COVID-19 a pandemic on March 11, 2020 (WHO, 2020b) to increase awareness of this disease. The status of this pandemic is a concern for the world to make various efforts to prevent the spread of COVID-19. One way to protect yourself from spreading COVID-19 is to use Personal Protective Equipment. Face shield is a personal protective device that functions to protect the face from exposure to dangerous substances in the case of the spread of the Covid-19 virus. A good face shield is a face shield that has a high level of durability, has high material quality, has a sufficient level of elasticity, and the costs incurred are not too expensive.In choosing the best alternative in making a decision, the right method is needed so that the best alternative is obtained from various predetermined criteria.Then the Analytical Hierarchy Process (AHP) method is used to select the best alternative material to be used in making the Face Shield. Based on the results of the research conducted, it can be seen that each alternative has the advantage of the criteria felt by the respondent.However, of the four criteria for selecting the face shield material, the most superior or chosen as the choice is mica.Judging from the percentage of mica against the Durability criteria is 31.7%, the percentage of mica against the quality criteria is 43.1%.

Abstract

A Learning environment is a place where the learning process takes place. In the implementation of the learning process, most student activities are carried out in a sitting position. Therefore the conditions and seating arrangements, the shape of the chairs, the various equipment and facilities that support the teaching and learning process must be a concern. An uncomfortable sitting position can affect the quality of learning. Also, uncomfortable lecture chairs will affect the user's concentration in learning so that this condition will accelerate the onset of fatigue. The application of the production process that we carried out for the manufacture of our redesigned lecture chairs (flexible chair) has been produced with a total time of 370 minutes with parts, namely, the mainframe, headrests, leg rests, back frame, and supporting materials with a total of 5 operators. We hope that this article can help other fellow students to produce an item and make an analysis of the production process.

Abstract

A process in a company or industry will never be separated from the name of the production, production is an important part of the running of a company or industry. This research aims to provide input to the company to be able to calculate the need for future production targets based on previous production data so that the company can prepare all production needs. Production can also be interpreted as an activity to increase the use of goods and benefits in fulfilling daily activities. In practice, a person or business entity that carries out production activities is called a producer. Producers produce goods to be sold to meet the needs of others and theirindividuals. Production activities, there is an activity of processing raw materials into semi-finished materials, and then proceeding from semi-finished materials to finished materials. Therefore, a separate focus is needed to determine the amount of production, output, and input that is done. One thing that can be done is knowing up to calculating the needs of all processes to the production target. While the focus of production activities from the production system to inventory is First, forecasting is important and foremost. Second, inventory control is very important in the production system for inventory, especially in planning the purchase and delivery of raw materials and components. Third, the production of large quantities of inventory items is more structured.

Abstract

Quality control is an activity that must be carried out by a company so that the products produced are in accordance with the standards set by the company in order to meet customer satisfaction. This research was conducted in order to obtain the results of the quality control analysis which then the results of the analysis will be used as an effort to reduce the number of defects in product packaging in the future at PG Kremboong. This research in solving the problem using the seven tools method. This seven tools method uses 7 quality control tools, namely Check Sheet, Control Chart, Cause and Effect Diagram, Pareto Diagram, Histogram, Scatter Diagram and Stratification so that a quantitative measurement is produced that shows the extent to which management objectives have been achieved. From the analysis using the seven tools, the defects in granulated sugar with 50 kg packages were produced, namely, less light prints (146), torn packages (299), dirty packages (224) and loose seams (200). The defect with torn packaging is the most dominant type of defect. Improvement steps to reduce the number of defects in sugar packaging in the future are carried out on 5 factors, namely humans, methods, machines, materials and the environment based on a comparison between the causes of the problem and the standards applicable in the company.

Abstract

In an increasingly advanced era, allproperty or home furniture is required to have arenewable innovation and efficiency. This is becauseproperty or home furniture currently has a very largemass or size. Large furniture sizes such as chairs andtables have an average area of 500cm2. Almost 90% ofIndonesian people have tables and chairs as the contentsof their household furniture. Not only functioned athome, in restaurants, cafes, malls, offices, in parks andall places where if there is interaction between humans,there must be chairs and tables as places for interaction.But sometimes the owners of chairs and tables oftencomplain about the size of the tables and chairs, so they need a large enough area to place these two items. Theproblem that exists in society today is the narrowing ofempty land in one place. Sometimes there is homefurniture that is not ergonomic, such as a chair that istoo high, a table that is too low and so on. By using thisanthopometric method, the measurements obtainedinclude a chair along the 95th percentile 25 cm, chairlength 33 cm 95th percentile, table length 68 cm 5thpercentile, chair height 39 cm 5th percentile, table height69 cm 5th percentile, and finally lower surface height. atable of 54 cm on the 95th percentile, and it is hoped thatthe manufacture of a chair flexibility table productdesign can overcome all the problems of land limitationsthat exist in today's society.
