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.

Abstract

In everyday life, both organic and inorganic waste remain persistent problems, with plastic waste being a significant environmental concern in Indonesia. According to the Ministry of Environment and Forestry, the national waste volume in 2021 was estimated at 68.5 million tons. Although most plastics are recyclable, efficient recycling depends on proper size reduction mechanisms. Polyethylene terephthalate (PET) is one of the most commonly used plastics, and polylactic acid (PLA) is also increasingly applied due to its biodegradable properties. However, there is a lack of comparative studies on blade design performance for shredding different plastic types. This study aims to develop a plastic shredder capable of processing PET, PLA, and their mixtures, and to evaluate the effect of three blade configurations—straight, zig-zag, and wave—on particle size outcomes. Experimental testing revealed that straight blades produced the largest average particle sizes: 5.63 mm for PET and 5.04 mm for PLA. Zig-zag blades yielded the smallest sizes: 4.70 mm for PET and 2.36 mm for PLA. The wave blade configuration produced intermediate results: 5.60 mm for PET and 4.17 mm for PLA. PLA consistently resulted in smaller particles than PET across all configurations. The zig-zag blade design proved most effective for fine shredding, particularly for PLA material. These results highlight the importance of blade geometry in optimizing shredding performance and plastic recyclability. This research provides insights for the development of efficient, small-scale recycling machines tailored to different plastic types and offers a practical approach for reducing plastic waste in local communities
