Abstract

Dalam industri alat berat, masalah keamanan dan pemantauan operasional unit yang ditinggalkan tanpa pengawasan telah menjadi isu signifikan. Risiko pencurian komponen alat berat dan kurangnya pemantauan real-time saat berada di daerah terpencil atau dari jarak jauh menjadi kendala utama. Penelitian ini bertujuan untuk mengembangkan Sistem Monitoring Portable untuk Operasional dan Anti Blind Spot guna meningkatkan keamanan operator dan orang di sekitar serta mengurangi titik blind spot. Sistem ini menggunakan teknologi kamera yang dipasang pada alat berat untuk pemantauan real-time dan deteksi dini potensi pencurian komponen. Metode penelitian yang dilakukan meliputi perancangan dan pemasangan Sistem Monitoring dan Anti Blind Spot pada unit alat berat. Dengan pemasangan Kamera 360 Portable, keamanan komponen meningkat berkat tersedianya sistem pemantauan video real-time. Desain dan implementasi Kamera 360 Portable memungkinkan pengambilan video dan gambar dari jarak jauh melalui perangkat ponsel operator atau pemilik unit selama terhubung dengan internet. Hasil penelitian menunjukkan bahwa penggunaan Kamera 360 Portable berhasil mengurangi persentase blind spot pada berbagai unit alat berat. Pada Excavator 313D, blind spot berhasil dikurangi sebesar 83,57%, sedangkan pada Bulldozer D3K, penurunan blind spot mencapai 79,82%. Sementara itu, pada Truk Kontainer, persentase penurunan blind spot sebesar 62,06%.

Abstract

Starting motors have an important role in running heavy equipment engines, accuracy in testing starting motor components is a very important factor. Practical learning using starting motor testing media is used to practice starting motor assembly and disassembly. The problems experienced by students in this course are limited practical equipment and lack of student skills regarding assembly and disassembly of motor starting systems. The aim of this research is to create learning media for testing motor starting systems and create a motor starting system testing guide so that it can be used as a practical tool in heavy equipment maintenance workshops. Experimental methods and work processes include: 1) determining materials, 2) designing the frame, 3) working on the frame, 4) making disassembly guides, testing, and starting motor assembly. The results of this research are that the learning media is equipped with the main components of the motor starting system, measurements that display motor starting system testing information, namely: the process of disassembly, testing and assembly of the starting motor, so that this learning media can increase students' understanding of the function and operation of the starting motor. system, as well as providing practical experience in testing and understanding related components.

Abstract

Sampah plastik menjadi masalah lingkungan global karena sulit terurai secara alami dan dapat mencemari air, tanah, dan udara. Untuk mengatasi masalah ini, proses daur ulang plastik menjadi solusi yang penting. Mesin pencacah plastik merupakan alat utama dalam daur ulang, namun banyak mesin yang masih menghadapi masalah dalam hal kapasitas dan kualitas hasil cacahan. Beberapa mesin pencacah plastik sebelumnya memiliki keterbatasan seperti ukuran cacahan yang besar dan ketidakstabilan dalam proses pencacahan. Tujuan penelitian ini adalah untuk mengembangkan mesin pencacah plastik dengan meningkatkan kapasitas dan menghasilkan cacahan yang lebih kecil dan seragam. Metode yang digunakan dalam penelitian ini adalah modifikasi desain mesin dengan mengganti sistem pemotongan menggunakan pisau dengan sudut kemiringan 45°, penambahan saringan, serta sistem pendinginan dengan pompa air untuk menghindari panas berlebih. Hasil penelitian menunjukkan bahwa mesin modifikasi mampu menghasilkan cacahan dengan ukuran rata-rata 7,7 mm x 6,4 mm dan kapasitas produksi 21,6 kg/jam. Mesin ini juga lebih efisien dengan waktu pencacahan rata-rata 2 menit 30 detik per 1 kg plastik, dibandingkan dengan mesin sebelumnya yang membutuhkan waktu 2 menit 48 detik. Kesimpulannya, mesin pencacah plastik yang dimodifikasi dapat meningkatkan efisiensi pencacahan dan menghasilkan cacahan plastik yang lebih kecil dan lebih seragam, yang mendukung proses daur ulang plastik yang lebih ramah lingkungan.

Abstract

This research explores the evolution of technology in pineapple peeling, from the use of manual knives to sophisticated pneumatic technology. The main focus is on pineapple peeling machine design, working principles, and calculating time efficiency between machine and manual peeling. The aim is to broaden students' understanding of designing machines and provide guidance for students in applying pneumatic technology. The study began with literature observations and field studies to collect price and specification data as well as information components about pineapple. Next, planning, manufacturing, and testing of the machine are carried out. Data was collected from both stripping processes for further analysis. The research results include machine designs with main components such as actuators, knife blades, knife fasteners, and machine frames, as well as pneumatic component specifications, which are explained in detail. A comparison of stripping times shows a significant increase in efficiency with the machine, with the fastest time of 9.09 seconds and the longest time of 447 seconds for manual stripping. This research contributes to the development of pineapple processing technology and increases efficiency in the fruit processing industry as a whole.

Abstract

Engine stand is an iron frame used as an engine mount. The working principle of an engine stand is to facilitate engine maintenance and repairs. Based on a case study conducted by the researcher, it was found that Politeknik Negeri Ujung Pandang Automotive Workshop did not yet have an engine stand, especially for the Suzuki ST 100 engine. This is also an obstacle when students carry out maintenance and repair practicums. The purpose of this study is to make it easier for students to carry out maintenance and repairs on the engine, so that the Suzuki ST 100 can be operated again as a learning medium for practicums. The place where the Engine Stand was made was at the Ujung Pandang State Polytechnic Automotive Workshop which was carried out from May to August 2024. The method in this study was to assemble the components on the frame, then install the engine on the engine stand that had been made, then overhaul the engine to ensure that the engine could work properly. The test results obtained were that all components could function normally again and the engine stand was safe to use because the strength of the engine stand frame to withstand an engine load of 90 kg, there was no change either bent or broken. The conclusion of this study is that the engine stand can be used as a strong engine mount and the Suzuki ST 100 engine can run normally after making several repairs and replacing its components.
