PROSES MANUFAKTUR MESIN DISC MILL DAN MIXER PENGGILING PAKAN UNGGAS PORTABLE Muhammad, Iqrok Dependence on relatively expensive commercial feed is one of the challenges faced by small-scale poultry farmers. One alternative solution is to produce feed independently using an integrated disc mill and mixer. This study aimed to: (1) identify the manufacturing process of a portable poultry feed grinding disc mill and mixer, including material selection, cutting, forming, machining, joining, and component finishing; and (2) analyze the performance of the manufactured machine in terms of performance, quality, economic value, and functionality. The research methods included a literature review, machine design, preparation of tools and materials, manufacturing, assembly, and machine testing. The manufacturing process consisted of material selection, cutting, forming, machining, joining, and finishing. Machine testing was conducted to evaluate performance, quality, economic value, and functionality, followed by analysis of the test results based on the predetermined specifications. Research results indicate that the machine's manufacturing process was successfully completed through stages including material selection, cutting, forming, machining, joining, and finishing. The machine delivers a production capacity of 10.5–16.8 kg/h, energy consumption of 0.72–16.67 Wh/kg, an average operating efficiency of 84.27%, vibration levels of 0.550–1.01 mm/s, and noise levels of 65.44–67.66 dB. Regarding quality, the grinding fineness on a 60-mesh sieve reached 76%–93%, while feed homogeneity showed a Coefficient of Variation (CV) of 1.08–1.32. The total manufacturing cost was IDR 935,000, and the machine weighed 8.025 kg, thereby meeting portability criteria. Consequently, the resulting disc mill and mixer unit offers performance, quality, economic value, and functionality suitable for small- to medium-scale poultry feed processing.

PERANCANGAN MESIN DISC MILL DAN MIXER PENGGILING PAKAN UNGGAS PORTABLE Selpi High feed costs are one of the main challenges faced by small- and medium-scale poultry farmers. One approach to reducing production costs is to produce feed independently through the grinding and mixing of raw materials. This study aimed to design a portable poultry feed grinding and mixing machine that integrates disc mill and mixer functions into a single unit, as well as to analyze its production capacity, energy consumption, grinding fineness, feed homogeneity, portability, and economic value. The research employed the Engineering Design Research (EDR) method, consisting of needs analysis, literature review, design specification determination, conceptual design, design calculations, technical drawing using SolidWorks, and design analysis and evaluation. The results showed that the machine successfully integrated disc mill and mixer functions using a single drive motor. The machine has dimensions of 30 × 30 × 40 cm, a weight of 8.025 kg, a container volume of 28.26 liters, an effective working volume of 19.78 liters, and an effective material capacity of 10.88 kg. The production capacity reached a minimum of 10 kg/hour with an average processing time of 102 seconds. The machine uses a 200.2-watt electric motor with an energy consumption of 0,72 -16,67 kWh. The grinding process achieved a fineness level of ≥70% passing through a 60-mesh sieve, while feed homogeneity reached ≥70%. The estimated design cost of the machine was IDR 935,000. Therefore, the designed machine is compact, lightweight, energy-efficient, and economical, making it potentially suitable for supporting independent poultry feed processing in small- and medium-scale farms.

Perancangan Sistem Penerangan Dan Pengisian Baterai Untuk Alat Peraga Kelistrikan Dasar Di SMK Muhammadiyah Kawali Gozali, Iqbal Maulana Basic electrical learning in vocational high schools requires practical media that can connect theoretical concepts with actual vehicle electrical systems. Limited teaching aids at SMK Muhammadiyah Kawali have constrained practical activities related to vehicle lighting and battery charging systems. This study aims to design and produce a simple, safe, easy-to-operate, and learning oriented teaching aid for basic automotive electrical systems. An engineering design method was employed through needs identification, literature study, alternative design selection, design modeling, technical calculations, fabrication, preparation of standard operating procedures, and functional testing. The teaching aid uses a 12 V DC source with major components consisting of a 12 V 35 Ah battery, headlights, turn signals, brake lights, reverse lights, position lights, switches, relays, fuses, a regulator, an alternator, and an electric motor. The first design alternative was selected because it was simpler, more economical, structurally rigid, and more mobile. The final teaching aid measures 700 mm × 600 mm × 800 mm and uses a 30 × 30 mm hollow steel frame with a thickness of 1.5 mm. The theoretical lighting load is 450 W with a current requirement of 37.5 A when all loads operate simultaneously; therefore, the lighting functions are operated alternately. The charging system uses a 12 V alternator with an 8 A output, corresponding to a theoretical power of 96 W. Functional testing showed that the lighting components could operate and the charging system increased battery voltage to approximately 14 V. The teaching aid is equipped with operating and assembly procedures as well as a practical module, supporting its use as a learning medium for basic vehicle electrical practice.
