Abstract

This study presents a flywheel-assisted regenerative braking system (FARBS) designed to improve energy recovery and voltage stability in electric vehicles (EVs). Conventional regenerative braking systems (RBS) suffer from short energy retention durations and voltage fluctuations, limiting their efficiency. The proposed system incorporates a spherical shell flywheel (120 mm radius, 20 mm thickness, 3 kg mass) directly into the braking mechanism to prolong energy recovery and optimise braking efficiency. Experimental results demonstrate a 439% increase in energy recovery duration, extending from 1.15 seconds (2000 RPM) to 6.2 seconds (4500 RPM). Voltage retention improves significantly, increasing from 10.3V to 19.2V, ensuring sustained voltage delivery. Kinetic energy storage attains 580 J at 4500 RPM, exhibiting a 23.4% increase over 2000 RPM. The flywheel system quadruples power output longevity, sustaining 6.40 W for 6.2 seconds at 4500 RPM, compared to 2.2 seconds without the flywheel. Energy recovery efficiency peaks at 16 J at 4500 RPM, an improvement of 275% in comparison to the baseline 4 J. Optimisation analysis confirms that increasing flywheel mass (1 kg to 3 kg) improves energy recovery by 194%, while a spherical shell flywheel improves energy recovery, achieving 327 J. This is twice as much as that of a solid disk (162 J). Carbon fibre outperforms steel, boosting energy recovery by 94%, while increasing the thickness from 10 mm to 20 mm, and resulting in a 200% efficiency gain. These findings underline the superiority of flywheel-assisted energy recovery, paving the way for high-efficiency braking solutions in EVs, public transportation and railway networks.

Abstract

The critique on the failure of Islamic organizations to represent the Islamic nature has been pointed towards employees’ competency in understanding the Islamic concept. Hence, this study seeks to delve into the understanding of the employee in Islamic organizations regarding the concept, implementation and challenges in such organizations by employing the qualitative method. The study involves three Islamic organizations namely Islamic Banking, Takaful and Islamic Property Management Company located in three states of the East Coast of Peninsular Malaysia i.e. Kelantan, Terengganu and Pahang. Managerial employees from the three organizations were interviewed and the outcomes were triangulated with the experts. The findings show understanding among managerial employees in Islamic organizations is appropriate but there are still more that need to be improved.

Abstract

Reproduksi merupakan kunci utama dalam pengembangbiakan ternak, karena proses reproduksi ternak yang normal diikuti oleh produksi ternak yang baik. Reproduksi dianggap sebagai salah satu aspek untuk meningkatkan produksi dan populasi ternak. Penelitian ini bertujuan untuk mengetahui efisiensi reproduksi Sapi Donggala di Kabupaten Donggala. Penelitian ini dilaksanakan di 5 kecamatan yaitu Kecamatan Tanantovea, Sindue Tobata, Sindue Tambosabura, Balaesang, dan Banawa Tengah . Penentuan lokasi menggunakan purposive sampling dan responden ditentukan secara accidental sampling. Pengambilan data menggunakan metode sampling terhadap peternak Sapi Donggala di 5 kecamatan tersebut. Data yang dikumpulkan adalah data Tahun 2022.  Variabel yang diamati berupa karakteristik peternak dan data reproduktivitas. Karakteristik peternak terdiri dari umur, pendidikan, dan pengalaman beternak. Sedangkan data reproduktivitas berupa umur pertama dikawinkan, lama kebuntingan, dan Calving Interval (CI).  Hasil penelitian diperoleh umur peternak terbanyak yaitu umur 15-65 tahun (96%), tingkat pendidikan terbanyak yaitu SMP (42%), pengalaman beternak tertinggi yaitu 3-10 tahun (67%), umur pertama dikawinkan tertinggi umur 1,6-2 tahun (46%), lama kebuntingan sebanyak 270-290 hari (69%), dan calving interval (CI) diatas 12 bulan (73%). Hasil penelitian menunjukkan bahwa efisiensi reproduksi Sapi Donggala di Kabupaten Donggala masih tergolong rendah

Abstract

Pembelajaran berbasis proyek Project-Based Learning (PjBL) merupakan pendekatan inovatif dalam proses belajar-mengajar yang memungkinkan siswa untuk mengembangkan kompetensi abad ke-21 seperti kolaborasi, berpikir kritis, dan keterampilan komunikasi. Artikel ini bertujuan untuk melaporkan hasil kegiatan pengabdian kepada masyarakat berupa sosialisasi pembelajaran berbasis proyek kepada guru-guru MA Bustanul Wa'izin NW Janggawana. Kegiatan ini meliputi pelatihan, workshop, dan pendampingan implementasi. Hasil kegiatan menunjukkan bahwa guru-guru mampu memahami konsep dasar PjBL merancang proyek pembelajaran, serta mengimplementasikannya di kelas. Kegiatan ini diikuti oleh 20 orang guru yang menjadi peserta kegiatan sosialisasi. Dari hasil kegiatan penelitian ini menunjukkan setelah dilakukan kegiatan sosialisasi, pemahaman guru pemahaman terkait dengan pembelajaran berbasis project pada kurikulum merdeka menjadi meningkat. Dari hasil posttest yang dilakukan setelah kegiatan, menunjukkan bahwa terjadi peningkatan pemahaman dari sebelumnya dari pretest. Sekitar 80% guru mengaku memiliki pemahaman yang baik setelah mengikuti kegiatan. Selain itu, dengan pemahaman yang baik, 80% guru memiliki komitmen untuk dapat melaksanakan pembelajaran berbasis project di kelas mereka. Tentunya hal ini disesuaikan dengan materi pembelajaran mereka dan diwujudkan juga dalam bentuk RPP.

Abstract

Limited forage for livestock during the dry season has an impact on low livestock productivity, so a source of feed other than grass is needed as an effort to utilize local resources.The purpose of research is voluntary feed intake level and organik matter digestibility adult female goat given by 3 different feed.  It was carried out on experimental farm of Hasanuddin University for 3 months. A total of six a head of adult male goats aged around 1.5 years with preliminary weights 11-15 kg were used and place at individual pen of 100 x 50 x 100 cm with 80 cm above ground level. This research was designed using RBSL with 3 treatments and it was used 2 heads of goat replication. The feed treatment covered 3 kinds of leaves, namely mango (R1), jackfruit (R2), and banana (R3). The voluntary feed intake (kg/day) was measured based on difference between given and remained feed weights.  The measurement of feed digestibility (%) using Total Collecting Method, covering total of feed comsumption and total of goat faeces (24 hours) separeted with urine. The research result showed that the voluntary feed intake level R1 leaves was heigher than R2 and R3 leaves, whereas the level of crude fiber digestibility and crude fat of R1 higher than  R2  and R3, but digestibility of crude protein R3 higher than R1 dan R2.

Abstract

Noise pollution can be categorized as a danger in silence. In school, noise pollution inhibits the focus of learning, impairs learning and cognitive development, for example, students' skills to think and understand both oral and written comprehension may be hampered by noise. Many schools in Malaysia experience excessive noise pollution as their locations are very near busy roads. This will be one factor that hinders the implementation of the education system in producing holistic students in order to prepare for the 4IR era. Knowing the importance of this problem, a group of researchers from UTM GREENPrompt, School of Civil Engineering, Universiti Teknologi Malaysia together with industry partners have built a special class called 'Serene Classroom' through a community project to overcome this problem. A classroom on the second floor of Sekolah Kebangsaan Kampong Pasir, Johor Bahru that has traffic noise exposure from the Skudai-Johor Bahru highway was selected for this purpose. The community project is in collaboration with the Johor State Education Department, Ministry of Education Malaysia and industrial partners, such as Vibrant Echo Company, Sanjung Sempurna Sdn. Bhd. and DZAZ Collection. The implementation of the project, the lessons learned from the project and challenges for the implementation are discussed. Technically, Serene classrooms significantly reduce the level of noise pollution for more conducive learning and have received better perceptions from students and teachers. Therefore, hopefully more ‘Serene Classroom’ community projects can be implemented in schools, especially in urban areas affected by high noise levels as a way to reduce the renovation costs on schools.
