Abstract

Peningkatan penggunaan plastik yang pesat akibat kemajuan teknologi dan gaya hidup praktis telah menyebabkan masalah serius dalam pengelolaan sampah plastik, terutama di lingkungan rumah tangga. Pada tahun 2023, sekitar 42,23% dari total sampah plastik di Indonesia dihasilkan oleh rumah tangga, dengan total mencapai 17,4 juta ton. Plastik sulit terurai dan memerlukan waktu ratusan tahun untuk terdegradasi secara alami. Meskipun pemerintah telah meluncurkan program 3R (Reuse, Reduce, Recycle) untuk menangani masalah ini, implementasinya di masyarakat terhambat oleh kurangnya fasilitas dan kesadaran untuk mendaur ulang sampah plastik. Salah satu solusi yang diusulkan adalah pengelolaan sampah plastik di tingkat rumah tangga melalui pencacahan, yang dapat mempermudah proses daur ulang. Penelitian ini bertujuan untuk merancang dan membangun mesin pencacah sampah plastik rumah tangga dengan proses pencacahan yang sederhana dan efisien. Mesin ini dirancang agar mudah digunakan di rumah tangga dan dapat membantu mengurangi volume sampah plastik. Hasil dari rancangan mesin ini mencakup berbagai komponen, seperti hoper input dan output, rangka, saringan, serta pisau bergerak dan pisau diam. Mesin ini menggunakan motor bensin dan sistem transmisi puli serta V-belt untuk menghubungkan motor dengan komponen pencacah. Mesin ini berhasil beroperasi dengan kapasitas 1100 rpm, menghasilkan ukuran cacahan plastik yang seragam, dan mampu mengolah 1 kg plastik dalam waktu 10 menit. Diharapkan mesin ini dapat mendukung upaya pengurangan timbunan sampah plastik rumah tangga dan mempercepat proses pendaur ulang.

Abstract

One of the impacts of population growth in a residential area is the problem of waste. If this problem is not immediately addressed, it will have a negative impact on residents around the settlement and the environment. This encourages collaboration from various parties, including universities and business actors of the Muara Abu Waste Bank to address this waste problem. This community service can be implemented by a team of lecturers from Nusa Cendana University with funding from the Ministry of Education, Science and Technology through BIMA. The objectives of this activity are first to provide education to residents of Oesapa Barat Village, especially around the Muara Abu coast, through waste bank management. The number of participants who attended this training was 50 residents, including waste bank customers. The second objective is to provide management training for the administrators of the Muara Abu Waste Bank (BSMA). The implementation of the activity consists of three stages: the preparation stage, the implementation stage, and the evaluation stage. The training material is the basics of waste bank management, including selection, sorting, packaging, and shipping. The following material introduces the management activities carried out during work, starting with customer deposits, sorting, weighing, storage, and bookkeeping of the waste bank account. For the waste bank administrators, the training focused on administrative systems and operational procedures. Educational activities also introduced creativity in recycled plastic waste products. The training, particularly for participants, resulted in increased knowledge of waste bank management. Before the training, only 38% of participants understood the material, whereas after the training this figure increased to 92%. Another impact was the rise in the number of BSMA customers, which grew from 39 to 68 by September 2025. This demonstrates the significant impact of this activity in raising public awareness of the benefits of waste banks.

Abstract

If without using an end plate, the wind direction is more spread out. From the main background of end plate testing, a study was conducted entitled "The Effect of End Plates on the Performance of Savonius Wind Turbines as Electric Power Generators". The test results show that with the same wind speed, it can produce greater turbine rotation if using an endplate compared to without using an endplate, from the results of the study at the same wind speed of 6.1 m / s it produces a rotor rotation of 652.5 rpm, Tip Speed ​​Ratio 0.8, power coefficient 0.5. In the turbine using endplate, this result is greater than the turbine without endplate by 488.9 rpm, Tip Speed ​​Ratio 0.4, power coefficient 0.2. The efficiency of the generator using endplate is better than without using endplate. Namely the maximum efficiency produced is 13.76% at a wind speed of 3.8 m/s. While without using endplate the maximum efficiency produced is 7.06% at a wind speed of 3.5 m/s.

Abstract

Indonesia has significant potential for hydropower development due to its mountainous and hilly topography, numerous rivers, and lakes/reservoirs that can be utilized as water energy sources. Water energy is harnessed for power generation using water turbines. One type of water turbine that can be used is a turbine with vertical or horizontal axis rotation, which can convert fluid energy into mechanical energy without requiring high head like other types of water turbines. One challenge is how to utilize the potential of relatively small water flow energy. Therefore, research is needed to transform constant water flow velocity to drive turbine or wheel shafts. The results show that the use of flow guide vanes on Savonius-type water turbines significantly affects turbine performance, with an average power coefficient increase of 5.80%. Additionally, the highest average power output of 3206.86% was obtained at a 45° deflector angle, which is higher compared to other angles such as 0°, 15°, 30°, and 60°.

Abstract

Roda gila merupakan salah satu komponen mesin yang berfungsi untuk menyimpan energi berupa energi kinetik hasil gerakan memutar poros engkol. Penelitian ini bertujuan untuk menganalisis pengaruh variasi susunan poros terhadap kinerja generator roda gila sehingga dapat digunakan sebagai bahan referensi pengembangan sistem penyimpanan energi mekanik berbasis roda gila yang lebih stabil. Pengujian dilakukan terhadap tiga susunan poros, yaitu tanpa roda gila, satu poros roda gila 30 kg, dan dua poros roda gila 12,5 kg dan 12,5 kg. Hasil penelitian dan analisis, dapat disimpulkan bahwa susunan poros roda gila berpengaruh terhadap kestabilan arus, tegangan, dan kecepatan putar. Tanpa roda, keluaran generator sangat tidak stabil. Susunan satu poros roda gila dengan massa 25 kg menunjukkan kestabilan yang membaik, meskipun masih terjadi penurunan saat beban aktif. Susunan dua poros roda gila yang masing-masing bermassa 12,5 kg memberikan stabilitas yang lebih baik daripada susunan satu poros karena energi kinetik total lebih besar pada poros A, yaitu 856,91 Joule dan poros B, yaitu 4.309,94 Joule. Dengan demikian, susunan dua poros roda gila bermassa 12,5 kg dan 12,5 kg merupakan yang paling efektif untuk menjaga stabilitas output generator.
