Abstract

This research aims to achieve the smallest possible turning radius for the knuckle joint while also meeting the regulations set by the Shell Eco-Marathon (SEM) committee regarding the design angles and lengths. Calculations and testing are conducted using simulation methods to obtain suitable angles and lengths for the knuckle. This simulation method involves a series of analyses to obtain data such as static turning radius diagrams, followed by an analysis using the camber calculation formula. The shape, angle, length, and design of the knuckle are considered with regard to driving safety factors. The findings of this study indicate that for a six-meter turning radius, the outer wheel requires a steering angle of δ_0=10.868°, and the inner wheel requires a steering angle of δ_i=77.397°. After improvements, for a 5.5-meter turning radius, the outer wheel requires a steering angle of δ_0=15.960°, and the inner wheel requires a steering angle of δ_i=71.321°. It can be concluded that this design can optimize the performance of the knuckle steering system.

Abstract

This study discusses the distribution of heat in the drum brake system using the experimental method using drums as the braking medium. The test was carried out using the brake test prototype process with the application of press and release. The test data collection technique is using three methods, namely by applying the same amount of press and release of the brake (20 seconds of pressure and 20 seconds of release), the application of press and release of the brake is released more than pressed (30 seconds is released and 10 seconds is pressed), and the application of press and release is more pressed than released (20 seconds pressed and 10 seconds released). The results showed that the highest temperature obtained in the application of brakes for 20 seconds and release for 20 seconds on standard drum brakes reached 61.8 º C, while applying the brakes for 10 seconds and releasing them for 30 seconds reached 46.3 º C, and applying the brakes for 20 seconds and releasing them for 10 seconds achieved a temperature increase of 73.5 º C. Penelitian ini berdiskusi tentang distribusi panas pada sistem rem tromol dengan metode eksperimen menggunakan tromol sebagai media pengereman. Adapun teknik pengambilan data pengujian yaitu dengan tiga metode, yaitu dengan pengaplikasian tekan dan lepas rem sama banyak (20 detik tekan dan 20 detik lepas), pengaplikasian tekan dan lepas rem lebih banyak dilepas dari pada ditekan (30 detik dilepas dan 10 detik ditekan), dan pengaplikasian tekan dan lepas rem lebih banyak ditekan dari pada dilepas (20 detik ditekan dan 10 detik dilepas). Hasil penelitian menunjukkan suhu tertinggi yang didapatkan pada pengaplikasian rem selama 20 detik dan lepas selama 20 detik pada rem tromol standard mencapai 61,8oC, sementara pengaplikasian rem 10 detik dan lepas selama 30 detik mencapapi 46,3oC, dan pengaplikasian rem 20 detik dan lepas selama 10 detik mencapai kenaikan suhu 73,5oC.

Abstract

The purpose of this research is to design a Computer-Based Inventory application of equipment in the Heavy Equipment Workshop of Padang State Polytechnic. Historically, the borrowing, returning, utility, and tool data recording have been manual processes involving a substantial amount of paperwork, often leading to errors in item placement, difficulties in accessing information, and the risk of data loss. This application not only provides a centralized platform for recording and monitoring inventory but also facilitates real-time information access. With this technology, workshops can avoid shortages or excesses of items, enhance the efficiency of heavy equipment utilization, and optimize maintenance cycles. The methodology employed in developing this application is the Waterfall Development Method. The research outcome is a computer-based application using Visual Basic and SQL Server Database. Penelitian ini bertujuan untuk merancang aplikasi Inventaris Berbasis Komputer peralatan di Workshop Alat Berat Politeknik Negeri Padang. Selama ini peminjaman, pengembalian, Utility, dan pendataan tools dilakukan secara manual menggunakan kertas sehingga memakan waktu dan kertas yang banyak, seringkali mengakibatkan kesalahan peletakan barang, kesulitan akses informasi, dan risiko kehilangan data. Aplikasi inventaris workshop alat berat ini tidak hanya menyediakan platform terpusat untuk mencatat dan memantau inventaris, tetapi juga memberikan kemudahan dalam mengakses informasi secara real-time. Metode yang digunakan pada pembuatan aplikasi ini adalah Metode Research and Development (R&D) dengan model Pengembangan Waterfall. Hasil penelitian ini adalah aplikasi berbasis komputer menggunakan Visual Basic dan SQL Server Database yang dapat digunakan untuk peminjaman dan pengembalian inventaris di workshop alat berat sehingga semua tools dapat terdata dengan baik.

Abstract

Most motorbike users desire enhanced engine performance beyond the usual level. Typically, users of 2-stroke motorcycles enhance engine performance by modifying the diameter of the carburetor venture and adjusting the compression ratio. This study employs an experimental approach to investigate the impact of alterations in venturi size and compression ratio on the performance of a 2-stroke petrol motorcycle. Torque measurements are obtained using a dynamometer, whereas fuel consumption measurements are obtained using a burette. Subsequently, the generated results are utilized as graphical representations for analysis. Based on the findings of torque research, the utilization of a venturi diameter of 29 mm coupled with a compression ratio of 7.5:1 demonstrates the most significant enhancement in torque. Meanwhile, the findings of the SFC research indicate that using a venturi diameter of 28 mm and a compression ratio of 7.5:1 yields the lowest value. Sebagian besar pengguna sepeda motor menginginkan kinerja mesin yang lebih baik daripada kinerja mesin standar. Pada umumnya pengguna motor 2 langkah untuk meningkatkan kinerja mesin melakukan perubahan pada diameter venturi karburator dan rasio kompresi. Penelitian ini menggunakan metode eksperimental yang bertujuan untuk mengetahui perubahan ukuran venturi dan rasio kompresi terhadap kinerja motor bensin 2 langkah. Pemgambilan data torsi menggunakan alat dynamometer sedangkan pengambilan data konsumsi bahan bakar menggunakan alat buret. Kemudian hasil yang diperoleh dijadikan grafik untuk dilakukan analisis. Mengacu pada pada hasil penelitian torsi, penggunaan diameter venturi 29 mm dengan rasio kompresi 7,5 : 1 menunjukkan peningkatan torsi paling tinggi. Sedangkan pada hasil penelitian SFC, penggunaan diameter venturi 28 mm dengan rasio kompresi 7,5 : 1 menunjukkan nilai paling rendah.

Abstract

This study explores the construction of a smoke machine for visualizing air movement in a wind tunnel. The device produces synthetic smoke using a flat nickel wire heating mechanism to heat liquid glycerin. During the test, three coils were selected to produces the smoke namely flat nickel wire, each with a resistance of 3.5 Ω. A power supply adapter with a 220V DC input and 24V 10A output powers the device. Glycerin liquid is used as the heating medium due to its safety and compatibility with the machine and wind tunnel equipment. The equipment heats 200 ml of glycerin, evaporating it in about 2-3 minutes to produce sufficient smoke. According to research, the device can operate for 4 minutes, allowing the observation of air movements in the wind tunnel using a slow-motion camera. Penelitian ini membahas tentang proses pembuatan alat smoke machine pada wind tunnel sebagai visualisasi aliran udara. Alat ini digunakan sebagai alat penghasil asap buatan (smoke). Peneliti merancang alat menggunakan alat pemanas tipe kawat nikel pipih dengan memanaskan cairan glycerin. Dari percobaan yang telah dilakukan peneliti memutuskan menggunakan 3 buah lilitan kawat nikel pipih dengan tahanan 3,5 Ω. Untuk arus supply menggunakan adaptor power supply dengan input 220V DC output 24V 10A dan menggunakan cairan glycerin yang akan dipanaskan, dikarenakan cairan ini aman untuk digunakan dan tidak menyebabkan kerusakan pada alat smoke machine maupun wind tunnel. Prinsip kerja alat ini yaitu memanaskan cairan glycerin sebanyak 200 ml sehingga menguap yang membutuhkan waktu sekitar 2-4 untuk menghasilkan asap yang baik dan bagus. Dari hasil penelitian alat ini dapat digunakan selama 4 menit menggunakan kamera slow motion di wind tunnel dalam proses visualisasi aliran udara.
