Abstract

The manipulator robot is one of the most widely used robots in the industry. The movement of the robot manipulator in this sector is a mechanical system that requires a mathematical modeling method to represent its geometric aspects and manipulate its dynamic parts. One of the most critical industries is healthcare. In this paper, a simulation is carried out on one of the factors, namely patient injection. The research results from this simulation used Webots software and was successfully simulated using a 6-degree-of-freedom robot. The positions simulated in several movements include: gripper position opens to take the needle, gripper closes to take the needle, the needle is held and directed to the patient, the needle is inserted into the patient area and pulled out again, returning to its initial position by placing the needle. However, this simulation does not add a needle so that only the 3D simulated robot movement can move by entering the expected position value to inject the patient according to the target.

Abstract

Raw materials as the most important factors in production activities, are obtained from suppliers. Suppliers are partners who ensure the availability of raw materials for the continuity of the company's production. Therefore, it is necessary for companies to choose the right supplier. The problem that occurs in Pak Wit's Tofu SME is that SMEs often change suppliers in procuring soybean raw materials because the SMEs do not have a fixed soybean supplier. This fact results in no certainty of raw materials from the supplier so that SMEs often experience a shortage of quality raw materials. This study aims to select the best supplier according to the criteria set by SMEs. There are 4 suppliers who are candidates with 4 criterias (price, quality, service and flexibility in delivery) used in choosing the best supplier. This research uses AHP to weight the criteria and TOPSIS to rank suppliers. The results of calculations with AHP found that the quality criteria were the first priority, with a value of 0.58. While with the TOPSIS method it was found that supplier 2 was the selected supplier with the highest preference of 0.941.

Abstract

Differences in cultural dimensions across countries can influence approaches and behavior patterns in education. Therefore, this study aims to analyze the influence of culture on problem-solving and decision-making in student projects in Indonesia and Germany. A comparative approach between the two countries identifies significant cultural differences in power distance, individualism, masculinity, uncertainty avoidance, long-term orientation, and indulgence. The research method used is a qualitative approach with descriptive analysis. Data was collected through interviews and observations of students involved in the project. The study results show that cultural differences affect students' approaches to problem-solving and decision-making. In Indonesia, group cooperation and conformity to social norms play an important role, while independence and critical thinking are prioritized in Germany. The implications of this research are the importance of increasing cultural awareness, developing collaborative skills, increasing independence and critical thinking, and empowering students with cultural knowledge. By understanding cultural differences and taking the right steps, educators can create an inclusive learning environment and prepare students to face the challenges of an increasingly globalized world.

Abstract

The sales report of SMEs at the Banyuwangi Festival is an indicator of the success of the festival. In the process of collecting the sales report, the Banyuwangi Tourism and Culture Office, as the current responsible party, still does it without an information system, making the management of the sales report of SMEs at the Banyuwangi Festival inefficient. Using the Rapid Application Diagram (RAD) method, the design of an ERP system in the form of a point of sale module based on the Odoo application at the Banyuwangi Tourism and Culture Office and the Banyuwangi Festival SMEs is carried out to obtain an efficient process of collecting the sales report of SMEs at the Banyuwangi Festival. The design using the RAD method is carried out to obtain results that are in line with user needs. The results of this research show that the designed ERP system can improve business process efficiency for institutions and efficient sales management for SMEs. The impact of this research is expected to improve data management accuracy, increase collaboration, and optimize sales of Banyuwangi Festival SME products.

Abstract

PT. Medion Farma Jaya is a company that produces livestock equipment, parts, and plastic packaging. One of the products produced by PT. Medion Farma Jaya is a 5-CC measuring spoon. This mass production process is based on what the company needs to package it with other products, or that can be from customer orders. This research is focused on the 5 CC measuring spoon product (SEN5CC) because, according to the company's 2021 historical data, there is a large percentage of rejected or defective products. Because of these problems, things can be done. The effect on the response to defective products is the setting of the injection Moulding machine by trial and error. Therefore, this research aims to find optimal settings for the machine for injection molding so that it can improve the quality of the product. To find out the optimal settings in this research, the response surface method was used. Based on this method is useful for getting the optimal level of factors or parameters that are significant to the response results. Based on research results, the factors used significantly influence optimal results, namely the melting temperature factor of 260 °C, holding pressure of 30 bar, and injection pressure of 62 bar. Therefore, the predicted response value was -25.1667, which meets the minimum target for the rejected product.
