Abstract

Tingginya angka kecelakaan lalu lintas yang melibatkan truk (12%) menggarisbawahi urgensi peningkatan keselamatan kendaraan berat ini. Penelitian ini dilatarbelakangi oleh seringnya insiden akibat patah as atau poros belakang. Untuk memahami fenomena ini, simulasi Finite Element Analysis (FEA) diterapkan guna memvisualisasikan sebaran tegangan dan deformasi pada poros belakang dump truck HINO 500. Analisis ini dilakukan dengan memvariasikan beban 26-35 ton, mencakup beban standar dan overload) dengan tujuan utama mengidentifikasi area konsentrasi tegangan dan potensi titik kegagalan fatik pada poros roda. Hasil penelitian menunjukan bahwa tegangan tertinggi terjadi variasi beban 35 Ton dengan nilai tegangan sebesar 1,76 x 10^8 N/m^2 dengan nilai tegangan tertinggi terjadi pada bagian ujung poros roda gigi dan ujung bagian dekat piringan. Nilai masih terbilang aman karena nilai tegangan lebih kecil dari nilai batas tegangan material yaitu 4,6 x 10^8 N/m^2. Sementara hasil simulasi FEA defleksi sebesar 4,026 x 10^-3 m dan hasil simulasi fatigue failure menunjukan pada variasi beban 26 ton memiliki life cycle terbesar 314.886 dan nilai life cycle terkecil terjadi pada variasi beban 35 Ton dengan nilai life cycle sebesar 46.523.

Abstract

In the sheet metal forming process within the automotive and heavy machinery industries, the Dandori frame component in the die system plays a crucial role as a compressive load-bearing support. This study aims to analyze the static performance of the Dandori frame structure in a press machine using SAPH440 material. The method employed is the Finite Element Method (FEM) based on SolidWorks software to evaluate displacement, von Mises stress, and the factor of safety parameters under load variations of 1000 kg and 2000 kg. Simulation results show that the maximum deformation is only 0.032 mm, indicating high structural stiffness. The maximum stress recorded is 14.286 MPa, uniformly distributed without excessive concentration, and well below the material's yield strength. Meanwhile, the factor of safety is evenly distributed with a value of 3 throughout the structure, indicating a safe design condition. Overall, the simulation results demonstrate that SAPH440 is a suitable and effective material for use in Dandori die frames under static load applications.

Abstract

Meningkatnya limbah plastik mendorong pengembangan teknologi daur ulang yang berkelanjutan, salah satunya adalah konversi limbah polimer menjadi filamen untuk pencetakan 3D. Penelitian ini bertujuan untuk merancang dan mensimulasikan pembebanan pada rangka mesin penghancur dan ekstruder filamen sebagai bagian dari sistem pengolahan limbah plastik. Proses penelitian meliputi identifikasi kebutuhan pengguna, penyusunan spesifikasi teknis, pengembangan dan seleksi konsep desain menggunakan metode matriks keputusan, hingga analisis numerik berbasis Finite Element Analysis (FEA). Dari tiga alternatif desain, konsep 3 terpilih dengan nilai evaluasi tertinggi (29 dari 40). Simulasi struktural dilakukan pada tiga jenis material: Aluminium 6061, Steel AISI 5140, dan Steel AISI 1018 HR. Hasil menunjukkan bahwa Steel AISI 5140 memiliki performa struktural terbaik dengan tegangan Von Mises terendah (40,18 MPa), faktor keamanan tertinggi (10,41), dan displacement yang relatif rendah (1,215 mm). Dengan mempertimbangkan kekuatan, kekakuan, dan margin keamanan, Steel AISI 5140 dipilih sebagai material optimal untuk pembuatan prototipe. Penelitian ini membuktikan bahwa pendekatan berbasis pemodelan dan simulasi mampu menghasilkan desain yang andal dan siap untuk tahap pengembangan lebih lanjut.

Abstract

Mining activities require regular maintenance of heavy equipment to ensure operational reliability. This study aims to design a special tool to support the rebushing process for the Torq Rod and Radius Rod of the HD7857 unit, enhancing work efficiency and quality. The research method includes interviews, needs analysis, and simulations using the Finite Element Analysis (FEA) method. The design results indicate that the tool can withstand pressure up to 600 bar (420 kN), with a maximum stress of 402.6 MPa, a safety factor of 1.14, and deformation within elastic limits. However, it is recommended to limit the pressure to 500 bar to maintain tool reliability. This tool design is expected to reduce errors in bushing installation, standardize work quality, and minimize unit downtime. The study contributes to the development of heavy equipment maintenance tools and can serve as a reference for similar future research

Abstract

The global energy crisis caused by the limits of oil reserves urging the needs for alternative energy solution, including a pyrolysis-based oil energy. In this study, we investigate the pyrolysis of corn cob biomass with varying particle sizes (3 mesh, 5 mesh, 7 mesh, and 10 mesh) to evaluate its effect on product yields and physical properties. Each experiment was conducted for 90 minutes using 300 grams of feedstock, pre-dried in a microwave oven at 120°C for 2 hours. The results revealed that the bio-oil yield decreased with smaller particle sizes, from 31.52% at 3 mesh to 26.12% at 10 mesh. Conversely, bio-char yield increased from 37.48% to 46.47%, while bio-gas yield decreased from 31.00% to 27.42%. This suggests that excessively small particle sizes reduce bio-oil yield due to uncontrolled reactions despite their higher surface area. The bio-oil density ranged between 1.0235 and 1.0353 g/ml, indicating consistent physical properties across particle sizes. The inlet and outlet temperatures of the reactor (T1 and T2) and condenser (T3 and T4) remained relatively increasingly stable, indicating consistent condensation of pyrolysis gases into liquid bio-oil. This study has successfully provided an insight into the optimization of particle size of the waste processing of corn cob into energy by using the pyrolysis method.

Abstract

Desa Palasari, Kecamatan Cijeruk, Kabupaten Bogor, memiliki potensi agraris yang signifikan terutama pada komoditas singkong dan ubi jalar putih. Namun, hasil panen sebagian besar masih dijual dalam bentuk mentah dengan harga rendah sehingga berdampak pada rendahnya nilai tambah dan ketergantungan petani terhadap tengkulak. Program Pengabdian kepada Masyarakat ini bertujuan meningkatkan keterampilan masyarakat dalam mengolah singkong dan ubi jalar menjadi produk bernilai jual, khususnya keripik, melalui rangkaian sosialisasi, pelatihan, dan pendampingan. Metode pelaksanaan mencakup penyampaian materi teoritis, demonstrasi langsung proses produksi, hingga praktik mandiri peserta dengan bimbingan real-time. Hasil kegiatan menunjukkan peningkatan signifikan pada pemahaman dan keterampilan teknis masyarakat, mulai dari pemilihan bahan baku, teknik pengirisan seragam, pengaturan suhu penggorengan, hingga penerapan varian rasa (original, balado, barbeque, sapi panggang, cokelat). Produk yang dihasilkan memenuhi standar mutu, higienis, serta memiliki daya tarik pasar lebih luas. Dampak nyata dari kegiatan ini adalah meningkatnya kapasitas masyarakat dalam menghasilkan produk bernilai tambah, terbukanya peluang usaha rumah tangga, dan berkurangnya ketergantungan pada tengkulak. Keberlanjutan program ini diharapkan terwujud melalui penguatan kelembagaan kelompok tani dan dukungan pemasaran digital sehingga produk keripik dapat bersaing di tingkat regional maupun nasional. Dengan demikian, pengolahan pangan berbasis singkong dan ubi jalar dapat menjadi strategi efektif dalam pemberdayaan ekonomi masyarakat secara berkelanjutan.

Abstract

Kebutuhan akan komposit ramah lingkungan mendorong pemanfaatan bio-fiber sebagai penguat. Penelitian ini mengkaji pengaruh variasi massa serat resam (Dicranopteris linearis) dan ijuk (Arenga pinnata) serta perlakuan alkalisasi NaOH 5% (2 jam) terhadap kekuatan tarik komposit bermatriks epoksi. Spesimen dibuat dengan metode hand lay-up sesuai ASTM D638 Tipe I pada tiga tingkat massa serat (1, 2, 3 g) untuk dua kondisi (tanpa alkalisasi dan beralkalisasi), masing-masing dua replikasi (total 24 spesimen). Hasil pengujian menunjukkan respons yang berbeda antara kedua serat. Pada ijuk, perlakuan alkalisasi menghasilkan tren kenaikan kekuatan tarik yang linier dan stabil seiring meningkatnya massa (27,42 → 31,88 → 34,59 MPa; R² ≈ 0,98), sekaligus menurunkan variasi data (coefficient of variant (CV) kelompok ≈11,6%). Tanpa alkalisasi, kekuatan material cenderung lebih lemah (29,07 → 19,08 → 36,06 MPa; R² ≈ 0,17) dengan variasi yang lebih tinggi (CV ≈30,4%). Pada resam, alkalisasi menghasilkan nilai optimum pada fraksi massa 2 g (22,43 MPa) namun menurun di 3 g (16,10 MPa), sedangkan tanpa alkalisasi nilainya moderat (16,53; 19,38; 16,12 MPa) dengan konsistensi lebih baik (CV ≈ 10,27% vs 18,61% beralkali). Seluruh kekuatan tarik melebihi acuan SAE J1717 (8,09 MPa).
