    KARAKTERISTIK PEMANEN DAYA LISTRIK BERBASIS GETARAN STRUKTUR

    La Ode Ahmad Barata; Samhuddin Samhuddin

    Rekayasa Mesin, Vol. 13 No. 3 · 2023 · Indonesian · DOAJ

    Mechanical vibration is a potential source of micro-electrical energy harvesting mechanisms for micro electrical power supply for IoT system networks, wireless and sensors where the power requirements are relatively lower and available independently. In this study, the characteristics of the…

    ANALISIS KARAKTERISTIK ALIRAN MELALUI PENAMPANG PERSEGI PANJANG MENGGUNAKAN MODEL TURBULEN LARGE EDDY SIMULATION (LES)

    La Ode Ahmad Barata; Samhuddin Samhuddin

    Rekayasa Mesin, Vol. 15 No. 1 · 2024 · Indonesian · DOAJ

    Dynamic response, fatigue, and stability issues of a structure are closely related to flow behavior past a bluff body structure. Flow past the free-end rectangular prism is investigated numerically using a Large Eddy Simulation (LES) turbulence model at Re = 22000. The prism model has a constant…

    Experimental Investigation of Bladeless Power Generator from Wind-induced Vibration

    La Ode Ahmad Barata; Kiwata Takahiro; Toshiyuki Ueno et al.

    International Journal of Renewable Energy Development, Vol. 11 No. 3 · 2022 · English · DOAJ Scopus

    The power harvester unit from flow-induced vibration (FIV) was designed to harness energy from low flow velocity based on the magnetostrictive effect on the galfenol (Fe – Ga alloy) strip induced by the oscillating bluff body. This study aimed to investigate the cross-section variation’s effect on…

    Socialization and training on production of bio-charcoal made from biomass waste using a double-tube reactor

    Lukas Kano Mangalla; Raden Rinova Sisworo; Budiman Sudia et al.

    Abdimas: Jurnal Pengabdian Masyarakat Universitas Merdeka Malang, Vol. 8 No. 1 · 2023 · Indonesian · DOAJ

    Proper handling of biomass waste can turn waste into something beneficial for society. One way that can be done is to convert biomass waste into quality biochar for energy needs and agriculture as a planting medium. This partnership program is intended to provide education and practical knowledge…
