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 urges the need for alternative energy solutions, including 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, which had been 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 stable, indicating consistent condensation of pyrolysis gases into liquid bio-oil. This study has successfully provided insight into the optimization of a particle size of the waste processing of corn cob into energy by using the pyrolysis method

Abstract

Kebutuhan energi yang terus meningkat diiringi pertumbuhan populasi dan ekonomi global mendorong pencarian solusi alternatif. Blueprint Pengelolaan Energi Nasional 2006-2025 Indonesia menetapkan target energi untuk tahun 2025, termasuk peningkatan penggunaan batu bara dan energi terbarukan. Limbah tempurung kelapa dan cangkang kemiri, yang masih belum optimal dimanfaatkan, menjadi fokus penelitian ini untuk digunakan sebagai bahan bakar alternatif dalam bentuk briket. Penelitian sebelumnya menunjukkan berbagai cara efisien untuk memanfaatkan kedua limbah tersebut. Modifikasi kompor briket dengan tempurung kelapa menghasilkan briket dengan nilai kalor tinggi, sementara briket cangkang kemiri dapat mengurangi polusi dan meningkatkan efisiensi termal. Penelitian ini mencoba mencampur kedua limbah ini dengan berbagai komposisi untuk mengevaluasi efektivitasnya sebagai pengganti minyak tanah yang semakin langka. Penggunaan tempurung kelapa dalam briket umum, namun, dapat menjadi mahal. Oleh karena itu, solusi yang diajukan adalah menambahkan limbah pertanian, seperti cangkang kemiri, untuk mengurangi biaya produksi tanpa mengorbankan kualitas briket. Penelitian ini membandingkan berbagai komposisi briket, termasuk CK50% + TK50%, CK40% + TK60%, CK60% + TK40%, CK30% + TK70%, CK70% + TK30%, CK20% + TK80%, dan CK80% + TK20%. Parameter yang diuji melibatkan kadar air, kadar abu, waktu pembakaran, dan shutter index. Hasil penelitian menunjukkan bahwa komposisi CK60% + TK40% dan CK20% + TK80% menunjukkan performa terbaik. Keduanya memberikan briket dengan daya tahan tinggi, stabilitas, dan efisiensi waktu pembakaran optimal. Kombinasi CK30% + TK70% dan CK20% + TK80% menunjukkan kadar air dan kadar abu stabil, sementara CK50% + TK50%, CK20% + TK80%, dan CK30% + TK70% menunjukkan waktu pembakaran yang lebih lama. Shutter index pada CK60% + TK40% dan CK20% + TK80% menunjukkan daya tahan yang kuat.

Abstract

Hydroponics is an agricultural system that requires electricity to drive water pumps that flow irrigation, and solar panels are tools to convert solar energy into electrical energy. The drawback of installing solar panels so far is static so that the power received is not optimal, considering that the sun is always moving around the earth. In this case a solar panel with a solar tracker system is used as a source of electrical energy for the water pump. The purpose of using a solar tracker on this hydroponic solar panel is to optimize the absorption of the energy received by the solar panel. The method used in this research is the method of literature study and experimental research. The research was conducted from March 4 - April 15 2023 from 07.00 - 18.00 WIB with 1 day of static position testing each, and 1 day of solar tracker solar panels every day. The total power obtained during the test was 2823.31W on the solar tracker system after deducting the power consumption of the solar tracker system, while in a static position the power obtained was 1843.71W. On the solar tracker system it takes 3 Hours 54 Minutes to charge the battery after the battery power is used for 13 hours. Meanwhile, in a static position it takes 6 hours. The conclusion from this study is that the solar panel solar tracker system in hydroponics is capable of producing a power increase of 53% compared to hydroponic solar panels in a static position.
