Abstract

The availability of sawdust as a growing medium for oyster mushrooms is becoming increasingly limited, thus alternative raw materials are needed. Rice straw, as an abundant agricultural waste, has potential for use, but requires chopping to an ideal size of 2–5 mm. This research designed and built a rice straw chopper with a 1 HP electric motor drive and a pulley-belt transmission system. The research methods included observations of mushroom farmers, literature studies, design planning, technical calculations (torque, power, capacity), prototype fabrication, and performance testing. The test results show that the machine's production capacity reaches 2.78–3.24 kg/hour with efficiency between 94–97% depending on the number of blades. The machine operates stably, produces cuts according to standards, and is easy to operate. These findings provide a practical solution for mushroom farmers in utilizing straw waste as an economically valuable growing medium.

Abstract

The CIGS (Copper Indium Gallium Selenide) thin film solar cells have been widely studied for a long time and have achieved an important position in the photovoltaic (PV) market. CIGS is one of the most promising materials for thin film solar cell applications. In this study, a thin film synthesis process was carried out on an ITO (Indium Tin Oxide) substrate using CIGS and TiO2 (titanium Dioxide) with deposition time variations of 30. 45 and 60 minutes using the PVD DC (Physical Vapor Deposition Direct Current) Sputtering method. Based on the test results, there was a shift in the diffraction peak along with the addition of the TiO2 layer, which indicated that the crystallization of ITO began to decrease and the TiO2 peak began to appear at deposition times of 45 minutes and 60 minutes. The formation of polycrystalline indicates good crystallization and surface uniformity. The highest layer thickness was obtained at a deposition time of 60 minutes, which was 426 nm, due to the particle agglomeration process on the substrate surface. The larger the particle agglomerates formed, the thicker the layer on the substrate surface. The results of the UV-Vis (Ultraviolet Visible) spectrophotometer test also showed that the overall band gap energy value corresponds to the ideal value for photovoltaic thin films, namely in the range of 1.04 eV to 3.5 eV.
