Abstract

Human resources (HR) need to be considered in a company, because HR is the most important factor in producing a quality product. Human resource management (HRM) is one of the fields of general management which includes aspects of planning, organizing, implementing and controlling. In a company, it can be said that one of the most important resources is a human being who is an employee, laborer or worker. At PT. In Panarub Industry, there are employees who are overloaded with work and some are underworked. The distribution of orders is different but the time to complete is the same so that it makes working hours increase (overtime), this causes less concentration at work and can reduce product quality. The current workload allocation from the FTE calculation results is 1 position below 1.28 and 6 positions above 1.28. The optimal need for people from the actual total FTE calculation is 156 to 163. Recommendations for PT. Panarub Industry In the D1 building, 7 people are recruited. This will have an impact on reducing the value of overtime in achieving future targets, and can minimize unwanted risks. With this research, the allocation of the performance burden of PT. Panarub Industry's employees will be in accordance with production needs and will run smoothly, so that productivity can reach the target.Keywords: Human resource management, Full time equivalent, Human Resources, Workload Allocation, Workload Analysis

Abstract

The table is a furniture that has a basic surface and legs as a buffer that varies in shape and function. The design of this product is intentionally dedicated to the needs of a table that has a large capacity to store food, drinks, and even other tools. But the dimensions of the OS Table is currently felt not to provide comfort to its users. Therefore, the idea arose to redesign the multifunctional table design (OS Table) to create comfort for its users. This research was conducted using the Anthropometry method. Based on the results of data processing that has been done by collecting anthropometric data, namely Popliteal Height (Tpo), Elbow Length to Hands (Pst), Sitting Elbow Height (Tsd), Coverage of Hands Forward (Jtd) and Length of Hand Range (Prt), then it can be concluded the results of the OS Table redesign by using the 5th percentile for the smallest and the 95th percentile for the largest resulting in the dimensions of the maximum length of the table is 150 cm and the minimum length of the table is 118 cm, the width of the table is 69 cm while the height of the table is 69 cm. This multifunctional table (OS Table) has been redesigned to achieve an ergonomic dimension, thus providing comfort for the user.Keywords: Tables , OS Table, Anthropometry, Ergonomics, Product Design

Abstract

In line with technological advancements and increased consumer expectations, quality has become a key factor in the service industry. PT. XYZ, which operates in the aircraft maintenance field, faces the challenge of reducing defects in the aircraft painting touch-up process. This research aims to reduce these defects using the DMAIC method. The DMAIC phases include define, measure, analyze, improve, and control. In the define phase, it was found that dust defects were the most dominant. Initial measurements showed an average DPMO (defects per million opportunities) of 12,129 and a sigma of 3.773. Analysis using the Ishikawa diagram identified the root causes of the problem, and FMEA helped determine the priority root causes that needed immediate improvement. The main causes of the aircraft paint touch-up defects were material cleaning that left fibers on the surface to be painted, and the spray gun being in an un optimized condition for use. Suggested improvements included procuring the appropriate cleaning materials and implementing a preventive maintenance checklist for the spray gun. The implementation of these improvements showed a reduction in dust defects, with the DPMO dropping to 3,477 and sigma increasing to 4.209. These results demonstrate that the improvements made were effective in reducing defects and enhancing painting quality.Keywords: DPMO, sigma, DMAIC, dust defects, aircraft painting.
