Abstract

Energi merupakan faktor penggerak segala aspek kehidupan, sehingga tidak heran bila energi menjadi hal terpenting dalam kehidupan manusia. Salah satunya yaitu Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) dengan variasa diameter pulley pada turbin, sebagai pengantar putaran ke dinamo menggunakan V Belt. Penelitian ini dilakukan untuk mengetahui variasi diameter pulley terhadap putaran dan daya yang di hasilkan turbin pelton. Pembuatan alat uji dilakukan di Laboratorium Material dan Teknologi Mekanik Jurusan Teknik Mesin Fakultas Teknik Universitas Halu Oleo. Dalam pengambilan data di gunakan beberapa variasi pulley sebagai perbandingan putaran pulley dan daya yang di keluarkan di namo. Pada pulley 1 dengan diameter 5,8 cm daya listrik yang di hasilkan sebesar 1,32 watt. Sedangkan pulley 2 diameter 7,6 cm daya listrik yang di hasilkan sebesar 0,67 watt. Dan pada pulley 3 diameter 10,16 cm daya listrik yang di hasilkan sebesar 0,41 watt. Dapat di simpulkan bahwa daya terbesar di hasilkan dinamo terdapat pada pulley 1 diameter 5,8 cm.

Abstract

This research is aiming to know the distribution of stress, strain, displacement as well as safety factor on bike tour chassis. The chassis was designed in Autodesk Inventor software and simulated using Autodesk Inventor software. Carbon steel and load of 120 kg, 150 kg, and 180 kg was used as material for the chassis. The results of this research indicate that maximum stress at the main frame can reach around 47,86 N/m2 in simulation and 45,83 N/m2 by manual calculation. On the other hand, the maximum stress can reach 2079×10 mm/mm in simulation and 2,29×10 N/m2 in from manual calculation. The maximum displacement happened on the frame is around 0,4684 mm in simulation while in calculation it can reach around 0,528. The maximum safety factor happened on the chasis is around 7,31 in simulation while in calculation it can reach around 7,63.

Abstract

Early marriage remains a significant social problem in rural areas, mainly due to low awareness among adolescents of the importance of education, psychological maturity, and economic readiness before marriage. This community service activity aims to provide counseling and guidance to school-age adolescents through the School-Age Adolescent Guidance (BRUS) program as a preventive measure to reduce the rate of early marriage. The implementation method is carried out through a participatory approach with stages of socialization, interactive counseling, group discussions, and psychosocial assistance. The counseling material covers healthy reproductive education, character building, motivation to continue education, and productive future planning. The results of the activity showed an increase in adolescents' understanding of the negative impacts of early marriage and a growing awareness to delay marriage until they reach the ideal maturity. Additionally, support from schools, parents, and community leaders is a crucial factor in the sustainability of the BRUS program. This initiative is expected to create a supportive social environment for adolescents to develop optimally without the burden of early marriage, thereby contributing to the improvement of human resource quality in rural areas.
