Abstract

Trash, especially plastic trash in the water, remains a problem in Indonesia due to the fact that conventional methods are restricted and employ inefficient heavy equipment. Automation-based technological solutions, such as the Remote Controlled (RC) Boat Trash Collector, are promising and sustainable answers. This research focuses on the design and implementation of a remote steering mechanism for a solar-powered RC Boat Trash Collector. This system is energized by solar panels as a source of renewable energy, a conveyor system for garbage picking, and a Jumper T-Lite V2 2.4 GHz frequency remote control as the main controller. The process of research was carried out by designing, constructing, and testing the performance of the ship, for example, testing the drive motor, servo rudder, conveyor system, and test range control. The test results showed that the steering system responds well with an effective range of up to 300 meters, and the solar panels can extend the vessel's operating time. The conveyor mechanism also performs well in gathering floating debris into a collection bin. By the integration of this system, the RC Boat Trash Collector has proven to be effective, efficient, and environmentally friendly in assisting waste cleaning in bodies of water while being a platform for the implementation of sustainable, renewable energy technology.

Abstract

Urban environments pose significant challenges for wind energy utilization due to highly complex, non-uniform, and turbulence-dominated airflow around buildings. Although the Savonius vertical-axis turbine is capable of operating under such conditions, its performance remains highly sensitive to installation placement and configuration. This study conducts a two-dimensional CFD investigation to evaluate the aerodynamic behavior of two tandem-arranged Savonius turbines mounted adjacent to a wall. Two blade-orientation configurations are assessed: Configuration 1, where the returning blades face each other, and Configuration 2, where the advancing blades are adjacent. Transient simulations employing a validated CFD framework with the Realizable k-ε turbulence model are performed at a 7 m/s inflow velocity across a range of tip speed ratios. The results reveal pronounced wall–flow interactions characterized by flow deflection and blockage effects. Configuration 2 demonstrates superior aerodynamic performance, achieving a higher maximum power coefficient over a broader TSR range. This improvement is attributed to a favorable “nozzle effect” generated between the advancing blade of the front turbine and the wall, which accelerates the incoming flow toward the rear turbine and enhances its inflow conditions. In contrast, Configuration 1 exhibits stronger wake interference and more severe blockage, particularly at higher TSR values. Overall, the findings indicate that an adjacent advancing-blade arrangement optimizes aerodynamic interaction and energy extraction for wall-mounted tandem Savonius turbines, offering valuable insights for the design of small-scale urban wind energy systems.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh media PhET Simulation terhadap hasil belajar kognitif peserta didik pada materi pewarisan sifat makhluk hidup. Latar belakang penelitian ini didasarkan pada rendahnya hasil belajar peserta didik serta kurang menariknya media pembelajaran yang digunakan di salah satu SMP Negeri di Bondowoso. Penelitian ini menggunakan metode kuasi eksperimen dengan desain Pre-Test and Post-Test with Non-Equivalent Control Group Design. Sampel terdiri dari dua kelas, yaitu kelas eksperimen yang menggunakan media PhET Simulation dan kelas kontrol yang menggunakan media konvensional (LKS). Pengumpulan data dilakukan melalui observasi, wawancara, dokumentasi, dan tes berupa pretest dan posttest. Analisis data menggunakan uji statistik non-parametrik Mann-Whitney. Hasil penelitian menunjukkan adanya perbedaan yang signifikan antara hasil belajar kognitif peserta didik kelas eksperimen dan kelas kontrol, dengan nilai signifikansi (2-tailed) sebesar 0,000 < 0,05. Hal ini menunjukkan bahwa penggunaan media PhET Simulation memberikan pengaruh positif terhadap peningkatan hasil belajar kognitif peserta didik. Media ini mampu meningkatkan keterlibatan dan pemahaman konsep peserta didik melalui visualisasi interaktif, serta mempermudah guru dalam menyampaikan materi secara lebih efektif. Oleh karena itu, media PhET Simulation direkomendasikan sebagai alternatif inovatif dalam pembelajaran sains untuk meningkatkan hasil belajar kognitif peserta didik.
