Abstract

This study aims to evaluate and compare warehouse management performance in Garut Regency based on five main variables: warehouse layout, equipment, SOP standards, human resources (HR), and occupational health and safety (K3). A mixed-method approach was applied, where the Analytical Hierarchy Process (AHP) was used to determine the weight of each variable, while the Simple Additive Weighting (SAW) method was employed to calculate the total performance score (utility score) and rank warehouses according to the weighted scores of each variable. Data were collected from eight different warehouses through direct observation, interviews, and warehouse check-up audits using a Likert scale. The results show that warehouse layout holds the highest weight at 44.95%, followed by SOP at 23.67%, equipment at 15.02%, HR at 9.75%, and K3 at 6.62%. Warehouse 5 achieved the highest performance score of 94%, indicating the most optimal warehouse management due to its strong performance in layout and K3, as well as high utility scores in the other variables. In contrast, Warehouse 6 obtained the lowest score of 58%, mainly due to poor layout, limited equipment, and weak SOP, highlighting the need for significant improvements. These findings emphasize that layout and SOP are the most dominant factors in determining warehouse management effectiveness, while the other variables serve as supporting elements. The results also indicate that larger-scale companies tend to achieve higher utility scores, reflecting greater maturity across the five evaluated variables.

Abstract

Forage grass is the main feed for ruminant livestock such as cattle and goats. However, the chopping process is still mostly done manually using a sickle, which is inefficient and requires considerable time and energy. This research aims to design and fabricate a simple grass chopper machine powered by an electric motor that is economical, compact, and easy to operate by small-scale farmers. The methods used include component design using 3D software, mechanical calculations (transmission, force, power, torque, shaft diameter), fabrication of the tool, and load simulation analysis using simulation software. The results showed that the machine uses an electric motor with a blade rotational speed of 835.71 rpm, driving force of 9.81 N, and power of 60.07 W. The motor side shaft diameter is 8 mm, while the blade side shaft is 10 mm. Simulation results indicated a maximum stress of 13,670 N/m², which is far below the yield strength of ironwood (ulin wood) at 55.64 MPa, resulting in a safety factor of 4068.9, indicating that the structure is safe. The maximum displacement is 0.00321 mm and maximum strain is 2.99 x 10⁻⁶, showing very small deformation, thus the structure is stiff and stable. The total fabrication cost of the tool is IDR 634,000. This grass chopper machine is deemed feasible for use and can improve the work efficiency of small-scale farmers.
