Abstract

Abstract: Airless tires are the best innovation for military tactical vehicles in carrying out the Army's main tasks for military tactical even peace support operations and war military operations. However, in its development there are still imperfections in the results, its fabrications in the adhesion between polyurethane and natural rubber. Therefore, the researchers aimed to develop the adhesion between polyurethane and natural rubber. In this research, a quantitative experimental method was used, namely by varying the hardness of natural rubber and polyurethane to determine the right hardness for airless tires for maximum adhesion. The problem that occurs is that the adhesive glue with the tire tread is problematic, resulting in a tire tread condition without air being released. In carrying out the research, a function test was carried out with a planned weight of 4,500 Kg. Based on the results of the tests that carried out, the correct result was obtained, namely the elongation at break of the most appropriate type of polyurethane L100, which was 9.287 MPa. In order to achieve the goal, namely the appropriate level of elasticity between polyurethane and natural rubber so as to be able to glue the spokes and tire treads, in the end the wheel rotation will rotate according to the desired elasticity.

Abstract

The tire without air is a tire that has a very extraordinary influence on the units of vehicle users, both public vehicles and tactical vehicles in the military. In addition to being used in the field of duty, this airless tire can be used for other supporting vehicles of army so there are not many obstacles during operations. Therefore, it takes good materials and proper calculations in making this airless tire tread so that in the future there are no obstacles when using it. The research methods used are experimental methods and field studies. The study was conducted repeatedly and the data was taken directly in the field. After mechanical testing of the rubber material is done to find out the physical properties of the strength of the material. Furthermore, the entire printing and assembly process is carried out and tested on the vehicle, for the conclusion of static analysis of rubber sample material that has been done has determined the proper hardness for the material connected with polyurethane, the appropriate hardness for this rubber is 80 KN/mm. The process has been tested from each sample of rubber hardness variations and the results are determined, in addition to rheometer testing or maturation process takes 5 minutes and is given a temperature of 100 °C and is assisted by hydraulic so that air from volcanic rubber is lost with the help of hydraulic pressure.

Abstract

Senjata Lawan Tank (SLT) merupakan senjata untuk menetralisir serangan tank. TNI AD memiliki 5 jenis SLT peleton dan 5 jenis SLT Kompi di seluruh satuan, tetapi disatuan TNI AD khususnya infanteri tidak memiliki munisi latihnya karena Roket SLT tersebut sangat mahal dan dapat digunakan sekali pakai saja. Politeknik Kodiklat TNI AD telah membuat roket berbahan Polyethylene. Dari roket tersebut hasilnya mengalami kegagalan dalam hal kekuatan pada roket latih tersebut berupa keretakan, dan mengalami deformasi. Pada Penelitian ini peneliti merancang sebuah body roket dengan konsep menggunakan bahan pvc (polyvinyl chloride). Tujuan penelitian ini adalah untuk untuk mengetahui kemampuan Bahan Body Roket SLT Latih dengan menggunakan bahan PVC (Polyvinyl Chloride).dari hasil uji tarik, uji impak bahwa PVC layak sebagai body roket anti tank latih. Kelebihan bahan PVC lebih kuat, lebih kaku sehingga pada saat diisi tekanan bahan tidak mengembang, tetapi mampu menerima beban yang kuat, serta mempunyai ketebalan dan keringanan yang sangat baik, kemudian dari hasil pengujian balistik dengan tekanan 15 bar sampai dengan 25 bar dengan jarak capai terjauh 164 meter menunjukkan bahwa roket tersebut secara keseluruhan permukaan ujung roket dan body roket tidak mengalami deformasi serta bentuk roket tidak mengalami perubahan dimensi seperti semula setelah menumbuk tanah yang permukaannya lembek maupun tanah yang permukaannya keras. Hal ini menunjukkan bahwa bahan PVC mempunyai kemampuan untuk body roket SLT Latih.

Abstract

Salah satu aplikasi penting dari peredaman getaran adalah pada joint coupling tank, khususnya pada kendaraan militer seperti tank FV101 Scorpion. Joint coupling adalah komponen yang sangat penting pada komponen mesin pada tank scorpion. Komponen ini berfungsi untuk penghubung antara mesin dengan rangkaian transmisi pada tank scorpion. Tujuan penelitian ini yaitu untuk mendalaminya secara lebih rinci dan mendapatkan pemahaman yang lebih akurat tentang bagaimana bahan karet dapat efektif berperan dalam meredam getaran pada komponen kritis, seperti joint coupling tank pada tank FV101 Scorpion. Metode penelitian yang digunakan yaitu pengujian mekanik dan uji vulkanisasi dari beberapa spesimen yang merupakan campuran dari beberapa material. Dari hasil penelitian menunjukkan spesimen dengan kompon campuran material dalam gram yaitu NR (75), SBR (25), ZnO (10), Stearic Acid (2), IPPD (3), Flexton (1) Carbon Black (75), CBS (1), Sulfur (2,5) dan Mineral (5) memeliki hasil uji mekanik dan uji vulkanisasi yang lebih baik dari spesimen lainnya yang ada dalam penelitian ini. Berdasarkan hasil ini dapat disimpulkan spesimen dengan campuran tersebut mempunyai kemampuan sebagai karet peredam pada joint coupling tank .

Abstract

A solar cell-powered water purification system (SC-WPS) was developed and installed to generate clean water using renewable energy at the Polytechnic of the Indonesian Army (POLTEKAD). Developed and implemented using renewable energy from a 100 Wp solar panel, a solar cell-powered water purification system (SC-WPS) was designed to address this issue. The battery performance of the system is the primary focus of this work, encompassing battery discharge, state of charge (SOC), and key electrical parameters such as voltage, current, power, and solar irradiation data. Under test, the solar panel generated up to 495.7 Wh/day with a peak power of 93.28 W. Although the voltage remained between 12.78 V and 12.84 V, the battery depletion process showed stability; the total energy generated increased from 92.2 Wh in the first hour to 766.1 Wh by the tenth hour. Although the solar panel efficiency of the system peaked at 15.2%, factors such as uneven sunshine and energy loss caused it to decline over time. These results underscore the need to maximize battery capacity and solar panel efficiency to ensure continuous system operation for water purification in areas with varying sunshine levels.
