The limitations of physical teaching aids pose a challenge to the effectiveness of learning in the heavy equipment course at Jambi Polytechnic. This study aims to address the issue by designing and building a low-cost excavator simulator prototype as an interactive learning medium. The research method consists of three main stages: component design using FUSION 360, manufacturing with 3D printing technology Fused Deposition Modeling (FDM) using PLA+ material, and assembly of a manual water-based hydraulic system utilizing syringes as actuators. The result is a functional prototype capable of accurately demonstrating all basic excavator movements, including base rotation, as well as boom, arm, and bucket movements controlled through levers. This simulator has proven to be an effective and practical teaching aid solution to enhance students’ practical understanding of mechanical principles and hydraulic systems in heavy equipment.

This research explores the use of oil palm empty fruit bunch waste fibers as an environmentally friendly reinforcement material for composite applications, aiming to replace conventional materials. The fabrication process utilized empty fruit bunch fibers, resin, and polylactic acid (PLA), with components produced using 3D printing technology. Mechanical properties were evaluated through tensile testing (ASTM D3039), compressive testing (ASTM D695), and Vickers microhardness testing (ASTM E384). The results showed an average maximum tensile strength of 8.18 MPa, while compressive testing yielded a maximum strength of 3.95 MPa. Vickers hardness values ranged from 19.53 to 29.04, with an average of 25.73. These findings highlight the potential of empty fruit bunch fiber composites as an alternative material that supports waste reduction and sustainability in the palm oil industry. However, further optimization of fiber fraction and surface treatment is needed to improve mechanical performance. This study not only contributes to scientific knowledge but also opens opportunities for sustainable material innovation in engineering applications

Purpose – This community empowerment program aims to enhance the independence and productivity of the Mina Usaha Bahagia Fishery Group through the implementation of an appropriate technology innovation—a fish pellet extruder machine—combined with integrated business management training. Design/methodology/approach – The program employed a needs assessment, the design and installation of a pellet extruder machine, and a series of technical and managerial training activities. Evaluation was conducted by measuring changes in production capacity, cost efficiency, and sales performance before and after the intervention. Findings – The implementation of the pellet machine significantly improved production efficiency by reducing the time required to produce 10 kg of feed from 120 minutes to 35 minutes and lowering production costs to Rp 6,500 per kilogram. Production capacity increased threefold, with enhanced pellet uniformity. On the managerial side, members demonstrated improved competencies in financial management and digital marketing, contributing to a 52% increase in group income. The establishment of a visual business identity further strengthened the group’s branding and marketing effectiveness. Originality/value – This program provides a distinctive integration of managerial training and appropriate technology application, which collectively demonstrated substantial improvements in both technical and business aspects within a community-scale fishery enterprise.

Industri manufaktur logam terus mengalami perkembangan pesat yang menuntut peningkatan efisiensi, dan kualitas. Salah satu proses pemesinan yang digunakan adalah proses end milling, yang mampu meningkatkan efisiensi dan presisi dalam pembuatan beragam komponen dari berbagai jenis material. Proses end milling memerlukan pencapaian sifat mampu mesin, yang memengaruhi kualitas produk, produktivitas, dan biaya produksi. Pemahaman parameter-proses seperti kecepatan spindel, kedalaman pemotongan, dan gerak makan menjadi kunci dalam mencapai hasil yang optimal dalam proses end milling. Penelitian ini memfokuskan pada pengaruh parameter-proses pada kekasaran permukaan material AISI D2, yang dikenal sebagai baja perkakas dengan ketahanan aus dan stabilitas dimensi tinggi. Hasil eksperimen menunjukkan variasi signifikan dalam kekasaran permukaan, dengan kecepatan spindel dan gerak makan memiliki pengaruh paling signifikan, diikuti oleh kedalaman pemotongan. Penggunaan kecepatan spindel yang tinggi menghasilkan permukaan yang lebih halus, sementara peningkatan gerak makan dapat meningkatkan kekasaran permukaan. Meskipun peningkatan kedalaman pemotongan cenderung meningkatkan kekasaran permukaan, dampaknya tidak signifikan secara statistik. Studi ini menyoroti pentingnya pengendalian parameter-proses dalam mencapai hasil yang diinginkan dalam proses end milling untuk material AISI D2.

Penelitian ini bertujuan untuk merancang dan membangun alat pemotong kentang yang efisien dan ergonomis untuk kebutuhan industri rumahan, terutama untuk mendukung produktivitas Usaha Mikro, Kecil, dan Menengah (UMKM). Permasalahan utama yang dihadapi pelaku usaha adalah lamanya proses pemotongan kentang secara manual yang berdampak pada waktu dan biaya produksi. Untuk itu, dilakukan perancangan alat dengan mempertimbangkan efisiensi waktu, kekuatan struktur, pemilihan material, dan mekanisme pemotongan. Metode penelitian meliputi tahap perancangan, pembuatan alat, serta pengujian kinerja alat dengan empat variasi ukuran mata pisau, yaitu 8 mm, 10 mm, 14 mm, dan 22 mm. Setiap variasi diuji sebanyak tiga kali dengan berat kentang yang sama, yaitu 1 kilogram. Hasil pengujian menunjukkan bahwa mata pisau 22 mm memberikan waktu pemotongan tercepat, rata-rata 0,67 menit per kilogram, sedangkan mata pisau 8 mm memerlukan waktu terlama yaitu 1,22 menit. Dengan demikian, alat ini mampu meningkatkan efisiensi kerja dan produktivitas dibandingkan pemotongan manual. Penelitian ini menunjukkan bahwa desain alat yang tepat dapat menjadi solusi praktis dan aplikatif bagi pelaku industri rumahan dalam pengolahan kentang secara cepat, seragam, dan efisien.
