Abstract

Pada penelitian ini dipaparkan tentang konversi yang dilakukan dengan mengubah kendaraan konvensional berbahan bakar bensin dengan listrik. Penggantian dilakukan dengan melepas Engine penggerak dan menggantikannya dengan motor penggerak yang secara otomatis ditambahkan dengan Baterai sebagai sumber energi. Selanjutnya dari hasil konversi tersebut dilakukan pengujian torsi dan rpm melalui Dynotest yaitu suatu metode pengujian performa mesin kendaraan (motor listrik) dengan cara melihat tenaga (power) dan torsi (torque). Torsi adalah kemampuan mesin untuk menggerakkan atau memindahkan kendaraan listrik dari kondisi diam hingga berjalan dan ketika berjalanpun ada variasi antara kecepatan dengan perubahan gigi yang dilakukan . Selain itu juga dengan Dynotest akan diketahui titik tertinggi nilai Torsi pada setiap gigi. Pada pengujian yang dilakukan didapatkan nilai perubahan gigi yang didapat dari gigi-1 kecepatan maks 20 km/jam, gigi-2 kecepatan maks 40 km/jam, gigi-3 kecepatan maks 60 km/jam dan gigi-4 kecepatan maks 80 km/jam. Pada kendaraan listrik ini pengukuran pada Ampere dan voltase dilakukan guna mengamati performa motor dan baterai sebagai komponen utama dan didapatkan nilai lonjakan pada setiap pergantian gigi.Lonjakan tersebut terjadi akibat dari kombinasi pijakan gas ,rem dan kopling yang bergantian guna mendapatkan nilai akselesari yang nyaman.

Abstract

A traffic accident is an unexpected and unintentional road event involving a vehicle with or without other road users which results in human casualties and property loss. Youth and productive age are one of the highest groups who become victims of traffic accidents. Therefore, safety riding is a program to prevent and reduce the number of traffic accidents. This research aims to determine the understanding of driving safety (safety riding) among automotive engineering education students at Muhammadiyah University of Puworejo. This research is a descriptive study with a cross sectional study design. This research was conducted from August - December 2023. The population in this research were students from the UMP automotive engineering education study program, from whom 160 research samples were then taken as respondents using random sampling. Data were analyzed using quantitative descriptive analysis. The research results show that students' understanding of the principles of road safety is in the high category, namely 52%. This means that students in the Automotive Engineering Education study program at Muhammadiyah University, Purworejo, have a good understanding of the principles of safety riding.

Abstract

The performance analysis of a 1 kWp off-grid Solar Power Plant (SPP) located on the terrace of the Energy Laboratory Building at Jakarta Polytechnic was conducted to determine the SPP's performance. The analysis involved comparing the design data with the actual installed system conditions. The methodology employed manual calculation of the SPP's power generation and simulation of its performance using PVSyst software. The analysis results indicated that the current performance ratio of the SPP is only 11%, primarily due to the low direct utilization of solar energy. A recommendation provided is to increase the load on the SPP system. Simulations conducted on the recommended load increase demonstrated a significant improvement in the performance ratio, with a value of 58%.

Abstract

Desa Pekutan khususnya di wilayah dusun 1,2,3 belum menggiat kegiatan bank sampah yang digunakan untuk mengelola sampah sehingga sampah dapat dimanfaatkan menjadi barang yang sedikit berguna dan bisa ditukar dengan nilai rupiah. Sehingga masyarakat harus bisa menyesuaikan dan memanfaatkan limbah ataupun barang yang sudah tidak terpakai khususnya yaitu limbah sampah organik maupun sampah non organik. Untuk Program kerja yang kedua yaitu pengadaan servis kunjung yang bekerja sama dengan astra honda purworejo. Permasalahan yang ada di Desa Pekutan, hanya terdapat sedikit bengkel sehingga warga sekitar kurang memperhatikan kondisi motor. Dengan adanya permasalahan tersebut kelompok KKN-T 36 memfasilitasi servis kunjung dengan harga yang terjangkau sehingga warga Desa Pekutan dapat memanfaatkan adanya acara tersebut. Program Kerja ketiga yaitu video profil. Teknologi informasi menjadi kebutuhan yang sangat penting bagi manusia. Media yang paling efektif adalah melalui video profil Desa Pekutan, diharapkan informasi yang diperoleh semakin lengkap. Video ini berupa video profil desa meliputi informasi geografis, mata pencaharian warga desa pekutan serta keadaan yang ada disekitar desa Pekutan.

Abstract

Ketosari Bener Purworejo Village is geographically one of the villages with narrow roads, with steep inclines and descents. Under these conditions, of course every vehicle, whether car or motorbike, that passes this road must be in good condition. A good engine condition is not enough if it is not supported by a good braking system. The condition of the engine and the performance of the brake system must be ensured that there is no interference or damage. This service activity aims to provide knowledge and information as well as practical or light skills to overcome problems and damage to motorbike brakes to the community. Service activities begin with preparation, implementation and reflection on activities. The training activities were carried out in the form of workshops, material presentations and questions and answers. The evaluation results obtained were: 1) Implementation of activities at 90%, 2) Mastery of resource material with a score of 95%, 3) Usefulness of the material or program with a score of 92%, and 4) Participant satisfaction with a score of 89%.
