The poultry industry plays a crucial role in meeting the growing global demand for meat. However, the feather plucking process remains a significant challenge, particularly for small-scale poultry farmers who often rely on manual methods that are time-consuming, labor-intensive, and potentially unhygienic. This study aimed to design and construct an affordable and efficient poultry feather plucking machine with a 2 kg processing capacity. The machine was designed using 3D modeling software and constructed using plastic materials for the bucket and rotating disc, and steel for the electric motor mount. The use of plastic components aimed to reduce production costs while maintaining efficiency and minimizing the risk of damage to poultry skin during the plucking process. Functional tests were conducted to evaluate the machine's performance, revealing an average processing time of 28 s per bird, a 30% reduction compared to manual plucking. The machine's efficiency was also assessed, demonstrating a 30% improvement over manual methods. The total production cost of the machine was Rp. 450,000, which is more economical than previous studies. Although the developed machine showed promising results, further study is needed to explore additional parameters such as energy consumption, maintenance requirements, and long-term durability. The incorporation of machine learning algorithms for automated cycle time optimization based on different poultry sizes and feather densities could also be investigated in future studies. Overall, this study contributes to the development of affordable and efficient poultry feather plucking machines, which can benefit small-scale poultry farmers and improve the overall efficiency of the poultry industry.

The design of executive chairs for trains was carried out to improve safety, comfort and aesthetics of the train. Seat design innovation was made by prioritizing passenger comfort and paying attention to the S curve of the passenger's spine. This research carried out a redesign of the Indonesian railway executive chair with the added advantage of a chair that can be tilted up to 40° from the initial position of 10°. After the design concept is selected, a simulation will be done on three critical parts of the train seat including chair frame, footrest, and footrest frame. According to investigation, there are facilities tailored to user needs, starting from a folding table, middle arm rest, reclining seat 40°, rotate system 180°, and footrest. The mechanism used for reclining seats with the help of a gas spring to adjust the backrest and a rotate system mechanism with plate bearings. Thus, the seat can be adjusted to the direction of the train's advance. The final chair dimensions of 1101x´1091´x632 mm and material ASTM A36, polypropylene, rubber.

The Pre-Delivery Installation (PDI) Department of PT. XYZ is tasked with carrying out the installation process of imported heavy equipment attachment units, including one of the leading excavator units. Obstacles that arise can affect installation productivity. The gap between the actual installation results of 78 units and the company's target of 156 units requires a solution or resolution to improve the process that can be implemented. Therefore, it is necessary to investigate the wait time associated with decreased productivity, which is the longest component of the installation process. This work has a purpose to analyze lead time of the excavator attachment unit installation process. The method is applied with a time study approach referring to data sheets and observations, then processing lead time data using pie charts, Pareto diagrams, and fishbone diagrams. Furthermore, we review the planning calendar, realization, and improvement engineering. Reduction is carried out by providing additional work personnel and procuring sanding machine tools to reduce the installation and critical time of the planning calendar. The realization condition for 562 minutes with the implementation of improvement engineering is reduced to 318 minutes. Thus, it can speed up implementation time of the excavator attachment in unit installation process to 224 minutes or 44%.
