Abstract

Penelitian ini bertujuan untuk merancang dan meningkatkan sistem pembangkit listrik tenaga surya dengan menambahkan sirip pendingin guna meningkatkan efisiensi operasional kerja. Tiga variasi prototipe dikembangkan dalam penelitian ini: prototipe pertama dengan 4 sirip pendingin, prototipe kedua dengan 6 sirip pendingin, dan prototipe ketiga tanpa sirip pendingin. Sirip pendingin disusun secara vertikal dan diselaraskan untuk mengoptimalkan aliran udara. Pengaruh sirip pendingin dievaluasi dengan mengukur berbagai parameter, termasuk suhu, intensitas, arus, tegangan, daya masuk, daya keluar, dan efisiensi keseluruhan panel surya. Temuan penelitian menunjukkan bahwa penambahan sirip pendingin menghasilkan suhu panel yang lebih rendah, sementara intensitas, arus, tegangan, daya masuk, daya keluar, dan efisiensi meningkat. Secara khusus, sirip pendingin juga berkontribusi dalam menstabilkan tegangan.

Abstract

This study aims to analyze the effect of blade edge angle geometry on the particle size distribution and quality of shredded materials, ranging from plastic to cardboard, using a rotary cutter–type shredding machine. The blade edge angles investigated in this study were 35° and 60°, with test materials consisting of polyethylene terephthalate (PET) plastic, plastic bags, and cardboard. Operating parameters of the machine, including rotational speed, number of blades, and blade thickness, were kept constant throughout the experiments. The analysis focused on shredding capacity, particle size distribution, and the quality of shredded products in terms of shape uniformity and process stability. The results indicate that the 35° blade angle produces higher shredding capacity, smaller and more uniform particle sizes, and better overall shredding quality compared to the 60° blade angle. In contrast, the 60° blade angle tends to produce longer and less uniform particles, particularly for flexible plastic materials, and increases the likelihood of material clogging during the shredding process. Based on these findings, it can be concluded that a blade edge angle of 35° is the optimal configuration for achieving efficient shredding performance and high-quality plastic output, thereby supporting recycling processes.

Abstract

This study investigates the relationship between microstructural changes and mechanical properties in an edge joint of ST 37 steel following Shielded Metal Arc Welding (SMAW) at 100 A using an E6013 electrode, without subsequent heat treatment. The analysis focuses on the Weld metal, Heat Affected Zone (HAZ), and Base metal through metallographic examination and Vickers hardness testing. The results indicate that variations in hardness values are strongly influenced by microstructural transformations induced by the thermal cycle during welding. The HAZ exhibits the highest hardness (172 HV), which correlates with an increase in the pearlite fraction to approximately 60% because of a relatively rapid cooling rate. This phase transformation leads to a harder microstructure, although it tends to be more brittle compared to the other regions. Meanwhile, Weld-metal records a hardness of 157 HV, and the Base metal shows 142 HV, reflecting differences in composition and thermal history across each zone. Overall, the average joint hardness of 157.33 HV demonstrates that despite significant microstructural modifications, the mechanical integrity of the welded joint remains acceptable and meets relevant standards.

Abstract

This study aims to analyze the effect of variations in the rotational speed of an electric motor on shredding capacity and the average size of shredded output in a plastic waste shredding machine. The method used is an experimental approach by conducting direct tests on a shredding machine using a single-phase electric motor with a power of 2 HP, with speed variations of 600 rpm, 900 rpm, and 1200 rpm. The test materials include plastic bottles, plastic bags, and cardboard, with a shredding time of 2 minutes for each test. The observed parameters include the mass of shredded material, shredding capacity (kg/h), and the average size of the shredded output. The results show that the highest shredding capacity for plastic bottles and plastic bags was achieved at a speed of 900 rpm, reaching 25.20 kg/h and 13.50 kg/h, respectively, while for cardboard material, the highest capacity was obtained at 600 rpm, reaching 28.59 kg/h. These findings indicate that increasing rotational speed does not always result in the highest shredding capacity for all materials, as the physical characteristics of the materials influence the shredding performance.
