Abstract

Work accidents are unwanted cases, often unexpected, that can cause loss of time, property, or death, and occur as part of or related to a work process in an industrial work environment. This study aims to implement the Hazard Identification and Risk Assessment Risk Control (HIRARC) process at PT Empat Perdana Carton Indonesia in Karawang to prevent and minimize work accidents due to lack of employee awareness of occupational health and safety. The method used to solve the problems that occurred at PT Empat Perdana Carton Indonesia is by using the HIRARC method. From the results of the implementation of the HIRARC method, it is known that the potential hazards that can occur in the sawing machine department are the noise produced by the sawing machine which is risky for hearing and sharp objects on the sawing machine are at risk of injuring the hands and feet. While the dangers in the production department are not using double mask which are at risk of respiratory disorders such as shortness of breath due to chemicals produced by the production process and not wearing hand PPE which is at risk of injury to the hands.

Abstract

Respiratory diseases are illnesses that attacks the respiratory organ system in humans. Unfortunately, the general public does not realize that symptoms such as shortness of breath, coughing and others can become serious illnesses if not treated promptly. Therefore, an expert system designed for early diagnosis of respiratory diseases was developed in this research. The Certainty Factor method is applied in this expert system in the form of a website-based software. From the results of the black box testing, it was concluded that the system can provide accurate diagnosis results. Furthermore, the final evaluation by users using the Technology Acceptance Model yielded a result of 89.21%, showing that the developed system can be accepted by users in diagnosing respiratory diseases effectively.

Abstract

Traditional retail, as well as micro, small, and medium-sized firms, play an important part in the Indonesian economy. However, with the rise of progressive business competition, such as competition from modern retail, traditional retail requires a strategy to better its business and performance. The purpose of this study is to identify consumer behavior in traditional retail based on data mining using Association rules-market basket analysis (AR-MBA). Data were gathered by collecting 150 shopping transactions. Furthermore, the pre-processing stage involved data cleansing, transformation, and reduction. The study's findings revealed that several association rules were established and validated. Based on these findings, various insights were obtained, including the fact that department 3 (snacks) is the most purchased item and is associated with items in other departments; there are association rules between powdered drinks and snacks, candy and snacks, toiletries, snacks, instant noodles and snacks, cigarettes and flavored drinks, and mineral water and flavored drinks. The findings are used to improve the performance and to expand the retail industry. This study recommends product stock management by increasing the number of products that consumers frequently purchase, product marketing strategies such as discounts, product bundling, and other promotions, and layout proposals based on association rules.

Abstract

The learning process that takes place at SMAS Dwi Putra still uses conventional learning methods that only rely on printed books and learning is not yet interactive. This research aims to implement a new method for continuing learning using education-based e-learning. The aim of this research is to determine the validity and practicality of education-based e-learning. This research methodology is Research and Development (R&D) using the 4D development model, namely define, design, development and disseminate. The subjects of this research were 10 class X students and 1 SMAS Dwi Putra teacher in ICT subjects, especially Microsoft Word material. The research results showed that the Edukati e-learning media validity questionnaire was 84% in the very valid category, and the material validity questionnaire was 94% in the very valid category. Apart from that, the practicality results for the teacher response questionnaire were 96% in the very practical category, and the student response questionnaire was 8.36% in the very practical category. According to this data, it can be concluded that the implementation of Edukati-based e-learning in ICT subjects, especially Microsoft Word material at SMAS Dwi Putra, was declared very valid and very practical.

Abstract

Decision support system is a system that can be a problem solving quickly, especially in ranking and identifying the score of choices from highest to lowest. The research conducted aims to use the MOORA approach in determining superior products, so that it can help companies in the marketing process, selection, and production decisions based on the best product recommendations produced. In this research, the case study discussed is the selection of production-worthy products to meet quality. If the process is still done manually, it takes a long time and the evaluation process becomes inefficient. Therefore, a decision support system was designed to support the evaluation process. The MOORA method is used in the implementation of this system to test its accuracy. The results obtained from this system will be tested through sensitivity tests to criteria, value weighting, and correction tests, with the aim of knowing the number of criteria that can be added.
