Abstract

The primary objective of this study is to investigate how different sizes of drive pulleys influence the performance of an electric motorcycle equipped with a BLDC motor. This was approached using an experimental technique that combined dynotesting and road testing where three drive pulley diameters of 42T, 44T, and 46T were used. While the road tests were intended to measure the top speed of the motorcycle, the dynotests were aimed at acquiring the necessary data to calculate the torque and power. Based on the results of this study, an increase in the drive pulley's diameter will increase the speed of the electric motorcycle, although it will lower the torque. It was found that the 42T drive pulley offers the greatest torque, which is 16.54 Nm at a power of 5.2 HP, and the 46T drive pulley allows for the greatest speed of 63.37 km/h. It is thus apparent that for performance to be properly tailored to the motorcycle, a balance should be struck in line with the intended purpose, which can either be acceleration or the cruising speed.

Abstract

Pondok Pesantren Miftahul Huda Doho, Madiun, memiliki potensi besar untuk pengembangan usaha berbasis sumber daya lokal, terutama melalui budidaya lebah kelanceng. Namun, potensi ini belum dikelola secara optimal. Program pelatihan ini bertujuan untuk meningkatkan keterampilan dan jiwa kewirausahaan santri dengan menggunakan metode kuantitatif melalui evaluasi awal dan evaluasi akhir untuk mengukur efektivitas pelatihan. Hasil menunjukkan tingkat keberhasilan mencapai 85%, didukung oleh antusiasme tinggi peserta dalam mengikuti teori dan praktik budidaya lebah kelanceng. Program ini memberikan dasar keterampilan untuk mendukung kemandirian dan pengelolaan usaha berbasis agribisnis secara berkelanjutan.

Abstract

The fan broom home industry in Jabalsari Village, Sumbergempol District, Tulungagung Regency, experiences production constraints in the fibre combing and straightening process, which is still conducted manually using simple and non-ergonomic tools. At Sapu Kipas Pak Slamet, a craftsmen group of fourteen members, this stage became the main production bottleneck due to long processing time, high physical workload, and inconsistent product quality. The lack of written work standards and production records also hindered performance evaluation. This community service programme aimed to improve production efficiency and productivity through the application of an appropriate-technology fibre combing and straightening machine and basic production management improvement. A participatory needs-based approach was applied through socialisation, baseline mapping, technology implementation, operator training, mentoring, evaluation, and sustainability planning. The developed machine, equipped with a single-phase electric motor, spiked combing rollers, worm-gear reducer, belt-pulley transmission, bearings, electrical panel, and safety covers, was fabricated, tested, installed, and operated independently by the partner. The programme also delivered three standard operating procedures, one training module, and two production recording forms. Production improvements are being monitored through daily records due to the absence of previous baseline data.
