Abstract

Penggunaan gearbox (differential mekanik) untuk stabilisasi roda kendaraan masih memiliki kekurangan yaitu perlunya perawatan secara rutin dan penyaluran torsi putar dari motor induksi ke roda tidak maksimal dikarenakan masih terdapat banyak losses pada gear. untuk memaksimalkan penyaluran torsi pada mobil listrik, kita membutuhkan suatu sistem untuk mengatur kecepatan motor penggerak roda kendaraan listrik secara elektronik. Penelitian ini membuat simulasi sistem electronic differential yang dikendalikan dengan teknik scalar control (V/F) dan teknik field oriented control dengan menggunakan software Simulink MATLAB version 7.8.0.(R2009a). Dari hasil simulasi dan pengujian, sistem electronic differential mampu bekerja seperti halnya differential secara mekanik, hal ini ditunjukkan saat kendaraan melaju di jalan yang lurus sistem electronic differential mampu memberikan referensi kecepatan yang sama dan referensi kecepatan yang berbeda pada kedua motor penggerak roda saat kendaraan sedang berbelok. Penggunaan teknik filed oriented control pada electronic differential memberikan performa yang lebih baik jika dibandingkan dengan teknik scalar control (V/F), hal ini di tunjukan dengan menghasilkan waktu steady state yang lebih cepat dan ripple torsi yang lebih kecil.

Abstract

ABSTRAK Kegiatan pengabdian kepada masyakakat di desa Dara Kunci kepada kelompok masyarakat nelayan tradisional ini bertujuan untuk mengurangi beban operasional dan meningkatkan produktifitas dan mengentaskan kemiskinan dalam jangka panjang. Dalam operasionalnya terutama melaut di malam hari, nelayan menggunakan aki untuk mensuplai daya lampu penerangan. Untuk penerangan 4 lampu 5 watt aki 12 volt hanya mampu bertahan selama 4 jam sehingga perlu melakukan inovasi/modifikasi mesin perahu agar bisa mengisi aki sendiri. Dengan menggunakan lampu penerangan yang telah modifikasi ini diharapkan nelayan dapat menambah jam operasionalnya yang biasanya hanya disiang hari menjadi malam hari. Bertambahnya jam operasi nelayan akan dapat meningkatkan tangkapan nelayan. Begitu pula dengan kemampuan nelayan merawat mesin perahu secara baik dan benar akan dapat menambah umur pemakain mesin. Sehingga kegiatan ini diharapkan dapat meningkatkan pengetahuan dan kesejahteraan masyarakat pesisir. Metode yang digunakan untuk mencapai tujuan kegiatan adalah metode penyuluhan perawatan mesin prahu dan pelatihan tentang teknologi lampu penerangan nelayan saat melaut pada malam hari. Untuk penerapan lampu penerangan saat melaut di malam hari dan penyuluhan perawatan mesin perahu digunakan metode Participatory Action Research (PAR) yaitu; melibatkan masyarakat kelompok nelayan secara langsung dalam kegiatan mulai dari penyiapan, perencanaan, dan pembuatan maupun pengoperasian alat sehingga nelayan dapat melaksanakan sendiri pembuatan lampu penerangan saat melaut di malam hari dan perawatan ringan perahu setelah kegiatan berakhir. Adapun hasil dari kegiatan ini adalah Mesin ketinting sebagai penggerak perahu dapat dimodifikasi dengan menambahkan alternator sebagai carge aki, dengan lama pengisian aki selama 4 jam dan peningkatan konsumsi bahan bakar sangat kecil yaitu 7 persen. Hasil dari penyuluhan ini adalah sekarang masyarakat lebih aman dan nyaman untuk melaut pada malam hari karena sudah ada lampu diperahunya yang sekaligus dapat membuat ikan mendekatinya. Dengan adanya pengisian aki mereka tidak lagi cemas akan kehabisan daya aki saat melaut. Begitu juga untuk perbaikan kerusakan kecil perahu sudah dapat ditangani sendiri.

Abstract

Electric vehicles are vehicles that are driven by electric motors using electrical energy derived from battery energy sources. Like most other electric vehicles, electric prototype vehicles are also controlled using throttle pedals on the steering wheel and also the braking system. This study also aims to determine how much electrical energy consumption is used in the vehicle, by varying the gear ratio and vehicle weight. The test method was carried out by releasing the throttle when the vehicle reached maximum speed, with the aim of being able to produce a lower level of energy consumption with higher efficiency. Gear ratio variations used were 6.43; 7.56; 8.57; 9.08 and 10.20 and vehicle weight variations used were 120.5 kg; 130.5 kg and 140.5 kg. The results of the test show that if the smaller the gear ratio used and the heavier the load from the vehicle, the greater the energy required. The results of this study indicate that, vehicles with lighter weight and with the use of larger gear ratio variations can reduce the consumption of electrical energy used. And can increase higher energy efficiency, so as to increase the maximum mileage range of the vehicle. The findings from this study can also provide additional information and valuable insights in the development of more efficient electric vehicles in the future.

Abstract

Continuously variable transmission (CVT) technology is currently something that is very commonly used in motorcycles for various reasons of practicality in use. This encourages the importance of CVT technology literacy in motorcycles to emerge in this context, because the CVT system has characteristics that inherently support fuel efficiency. CVT allows riders to enjoy smooth transmission ratio changes without the need for manual gear shifting. This is an advantage especially in urban traffic situations that often involve stop-and-go patterns, where the CVT system can keep the engine operating at an efficient speed. However, in order for the benefits of CVT to be felt to the maximum, riders need to understand how this technology works. CVT technology literacy includes knowledge of how to use the CVT system optimally, avoiding riding styles that can put excessive stress on the transmission, and understanding the maintenance needed to maintain CVT performance. Riders who are educated in CVT technology will apply fuel-efficient riding techniques, such as avoiding sudden acceleration or unnecessary braking, which will not only increase fuel efficiency but also extend the life of the CVT. In addition, regular maintenance, such as checking and replacing the CVT belt according to schedule, can prevent premature damage and ensure that the motorcycle continues to operate at its best performance. With adequate literacy, riders can not only save fuel and operational costs, but also support environmental sustainability by reducing emissions. Therefore, increasing public understanding of CVT technology is a strategic step to create more technologically aware and responsible motorcycle users.

Abstract

Borok Toyang Village, located in the West Sakra District, East Lombok Regency, has a very high potential for livestock farming, especially cattle and goats. However, farmers still face difficulties in providing high-quality feed for their livestock to ensure optimal growth and productivity. The traditional feed used reduces livestock growth and increases production costs. To address this issue, the socialization of elephant grass fermentation, a better livestock feed innovation, was carried out. This activity involves initial observation, socialization, and direct training for farmers in Borok Toyang Village. Observation was conducted to determine the condition of the farms and the feeding patterns. The training included the direct preparation of fermented feed, and socialization was provided through seminars and open discussions about the benefits of fermentation. The results of the activities show that farmers have a better understanding of the importance of innovation in providing livestock feed. It has been proven that the fermentation of elephant grass accelerates livestock growth, improves the nutritional quality of feed, and reduces dependence on expensive commercial feed. Additionally, this method helps ensure the availability of quality feed, especially during the dry season. Some farmers have expressed interest in adopting this method independently and plan to form small groups to share experiences in its implementation. Farmers in Borok Toyang Village hope to independently produce more livestock, reduce production costs, and enhance the village's economic resilience through livestock farming with this socialization and training.
