Abstract

The risk of Musculoskeletal Disorders (MSDs) is one of the problems that often occurs in manual handling workers with heavy loads in repetitive work movements for a long time. One example of this movement is the manual palletization activity of Bottled Drinking Water products at PT XYZ. Initial observations showed that 18 workers felt limb discomfort while stacking cardboards of 18kg water bottles. This study aims to determine the Recommended Weight Limit (RWL) used to measure the lifting load limit for workers; Lifting Index (LI) measurement that can describe the level of safety of lifting loads.The results showed that the load limit in drinking water palletization activities exceeded RWL, while the results of the LI calculation showed that manual palletization activities of bottled drinking water had a score of 6.4 where the LI score according to the safety standards of lifting activities was 1. These results indicate that manual palletization activities are not safe for workers and are at risk of causing MSDs. This is evidenced by the results of the assessment of the level of work posture discomfort using NBM which shows the highest pain score in the lower back of the body. Furthermore, workload measurement results vary from heavy to very heavy. From all parameters measured, it can be seen that the manual palletization activity of Bottled Drinking Water products at PT XYZ is very poor. The recommendation that can be proposed is to change the work system of manual palletization activities to a mechanical or automatic system.

Abstract

Gudeg is one of traditional food prefered by public in Yogyakarta. To meet the standard and quality requirements for Gudeg product the industry is required to be capable of making improvement to production procedure in each flow of its production activities. An analysis of the implementation of GMPs (Good Manufacturing Practices) to Gudeg SMEs in Yogyakarta is deemed important.  It aims to identify the factors of the highest non-conformities and to provide solutions in creating a better food production procedure for Gudeg SMEs in Yogyakarta. The aspects that had the highest incompatibility values were formulated using the 5 Why's Analysis method and Ishikawa diagrams. The research aims: 1) to analyze the implementation of GMPs in one of the SMEs in Gudeg production in Yogyakarta; 2) to analyze the factors of the highest discrepancy with the implementation of GMPs; and 3) to give suggestions for the improvements such nonconformities. The results of the assessment of the implementation of GMPs in Gudeg SMEs showed that the level of GMPs implementation was good with a conformity (93.30%). The highest discrepancy was found in the employee aspect (37.5%) due to the absence of employee training regarding food sanitation and safety in the industry, also the lack of reference standards for the application of GMPs in industry.

Abstract

Roasting process is the most important process in processing Phaleria macrocarpa (also called as Mahkota Dewa/God’s Crown) into dried tea product. It aims to change the color, texture, and reduce the water content of Phaleria macrocarpa to extend the shelf life and simplify the distribution and serving process. This study aims to determine the effects of temperature and time in the roasting process on the physicochemical properties of Phaleria macrocarpa including water content, color, texture, and their effect on antioxidant activity (AOA) using DPPH method. The design experiment for this study was by varying the treatments at temperature of 80℃, 100℃, and 120℃ and time at 40, 60, and 80 minutes in the process of roasting Phaleria macrocarpa fruit. Furthermore, the tea of Phaleria macrocarpa produced in each treatment and the standard samples from the industry were analyzed for its physicochemical properties and antioxidant activities. The results of multiple regression analysis showed that the correlation coefficient (r value) between the variables of temperature and time on water content, color, and AOA was 0.827; 0.944; and 0.886 respectively. Increasing temperature and roasting time caused a decrease in water content, color and AOA; however, multiple regression analysis showed a weak correlation between temperature and time on the texture of Phaleria macrocarpa with a correlation coefficient (r value) of 0.095. The best treatment based on research that has been done was found at a temperature of 100℃ for 60 minutes with a total score of effectiveness index (EI) of 0.688. In this treatment it was found the average water content at 1.31 ± 0.20%, lightness at 21.80, redness at 5.10, yellowness at 9.65, texture at 1.16 kgf, and AOA at 82.33 ± 0.30%. Meanwhile, the best physicochemical characteristics and AOA based on the effectiveness index showed results close to the standard sample test values. The slight difference was found in the value of the water content in which at the same temperature and roasting time it showed different values between the test samples and standard samples. The water content in standard samples showed a higher value, probably due to poor storage process. Hence, it is deemed necessary to improve the storage process of Phaleria macrocarpa tea product on industrial scale.

Abstract

One of the impacts of the COVID-19 pandemic is the delay in face-to-face activities, one of which is the delay in holding job fair event. The reduction in the implementation of offline job fairs has encouraged job seekers to seek work through online media. Website X and Website Y are examples of websites used to find jobs online. With the current increase in find jobs through Website X and Website Y, the usability and display of their website need to be evaluated. Usability and display evaluation aims to identify usability problems and correct these problems, to increase the usability of a design. The objective of this study is to find out whether there is a significant difference of the time needed to find job vacancy between Website X and Website Y website, to find out whether there is a significant difference of the time needed to find job vacancy between male and female on both Website X and Website Y website, and to find out user perspective on both Website X and Website Y website related to system aspects, user aspects, and interaction aspects by using usability questionnaire. The advantage of this research is that it can help website developers by pointing out areas that require development or improvement. Other than that, this study might provide suggestions for job vacancy websites that are more user-friendly. Based on the results of the study it was found that Website X and Website Y had problems related to user perceptions of the safety of using the website, user comfort with using colors on the website, and the user's ability to remember menus and website appearance. The results also show that there is a significant difference between the time needed to carry out activities on Website X and Website Y.

Abstract

PT Perkebunan Nusantara VIII Pasirmalang (PTPN VIII) is a tea processing industry that has effectively transitioned into a shareholder in black tea powder. The attainment of tea processing outcomes did not rise in response to the increased demand. In actuality, 2020's product output never quite reached the production goal. The pandemic conditions at the time had an impact on black tea processing as well. The company hasn't looked into the causes of unsteady manufacturing in more detail. Consequently, in order to assess the performance of the business, production productivity must be measured. By using a variety of input elements to determine the company's performance value, the Objective Matrix (OMAX) method is the tool utilized. Three inputs are taken into consideration while calculating productivity: labor, electricity, and raw materials. The OMAX method was used to measure manufacturing process productivity, and the results indicate that in 2020, December 2020 had the best achievement and February 2020 saw the lowest.
