Abstract

Horseshoe is used to avoid the failures of horse's hooves due to extreme impact and wear loads. The horse's hooves are repeatedly subjected to loadings during walking, trotting, running and jumping. In this research, we introduce a newly developed horseshoes made of polymeric composite materials. The horseshoes are placed inside the leather boot; it is a specially designed for horse. The process of making horseshoes and horse boots were discussed and the responses of the horse shoes as well as horses were analyzed. The horses were subjected to a series of testing, e.g., walking, trotting, and running. The result of the tests indicate that horseshoes and horse boots are quite strong, light, and safe to be used on horses. The response of horses shows that the horseshoe and boots are quite comfortable for them. This can be seen because there are no significant behavioral changes of the horse before and after wearing the boot. After being used to, it was shown that there is no damage or crack of the horseshoe. Therefore, it can be concluded that the composite horseshoe is safe and good to be used as horseshoe material.

Abstract

Pegas ulir adalah salah satu komponen elastis, biasa dibuat dari lilitan kawat baja dengan sifat pegas yang elastis, pegas berfungsi untuk menerima getaran dan memberikan gaya akibat dari beban yang di berikan seperti pegas yang terpasang pada vibrating screen di stasiun pemurnian. Gaya yang di hasilkan sebuah pegas biasa tarikan atau tekanan. Pegas merupakan salah satu komponen penting pada alat vibrating screen karena pegas digunakan untuk menopang beban dan juga menghasilkan getaran yang di teruskan dari getaran bandu pada elektromotor vibrating screen. Karena pegas menerima beban tekan dan juga beban tarik maka haruslah di perhitungkan kekuatan pegas yang di gunakan sesuai dengan beban yang di terima dan dilakukan perawatan agar menghindari dari kerusakan pada pegas. Pada penelitian ini di lakukan pengujian pada pegas ulir vibrating screen bahan baja AISI 1045 dengan kategori baja karbon menengah menggunakan metode uji kekerasan dan uji tarik. Pada uji kekerasan besarnya vickers hardness rata-rata (Hv) pada pegas yang terjadi pada bahan I, II dan III adalah 274,5866 Hv, 120,8289 Hv dan 326,6700 Hv. Pada uji Tarik besarnya tegangan tarik (σB) pada pegas yang terjadi pada bahan I, II dan III adalah 101,48 Kgf/ , 105,49 Kgf/ dan 109,47 Kgf/.

Abstract

The chain is a series of links or rings that are connected or fixed so that they form vertically. Chains are used to move luggage or as a substitute for additional strength. One of the most commonly used chains is made of the hardest metal, steel. One is a chain roller mounted on an empty coil conveyor. This conveyor serves to carry empty coils to the shelter. The chain also plays a role in the distribution of materials from one place to another to make it more efficient. In this study, the authors tested five chain materials to determine the breaking stress and the factors that influence chain breaking. After the authors tested the steel chain material, the value of the chain tensile stress (σB), based on the test results after averaged was 880 Kgf/cm2, and the chain fracture stress (σF) after averaged was 764. is Kgf/. the average strain on the chain (ԑ) is 8.9°. Causes of chain breaks are overload, fatigue, improper heat treatment, improper design and manufacture, and lack of maintenance.

Abstract

This study aims to determine the mechanical structure of polymeric foam reinforced with fiberglass horseshoes. Observations are focused on the average maximum impact force and the average maximum impact stress obtained from the free fall impact test. Testing the free fall impact structure with an impactor weight of 10 kg on five horseshoe test specimens 1, 2, 3, 4 and 5 with an impact distance of 2.5 meters, 2 meters, 1.5 meters, 1 meter and 0.5 meters, the results are horse shoe test specimens does not experience cracks / broken. The results obtained are in the form of the highest stress on the 1A test specimen with a stress value of 0.154 MPa and the maximum force found in the 1A test specimen of 874.95 N. with an impactor weight of 12.5 kg the test specimen cracks / breaks at a height of 3 m and 2.5 m, resulting in the highest impact stress value in sample 6B of 0.21 MPa and a force of 1185.5 N. then the force and stress will be higher but the level of damage will also be greater.

Abstract

Screw conveyor merupakan salah satu pemindahan bahan yang digunakan didalam industri yang bertujuan untuk mengangkut material. Pemilihan penggunaan screw conveyor untuk mengangkut material tersebut dikarenakan lebih efektif dalam memindahkan material, lebih ramah terhadap lingkungan serta memilki struktur yang sederhana dan sangat efisien. Pengaruh sudut kemiringan screw conveyor dengan variasi 10°, 15°, 20° terhadap beban maksimum. Objek observasi yang penulis tuangkan dalam penelitian ini adalah pengaruh sudut kemiringan screw conveyor terhadap beban maksimum pada sudut screw conveyor. Tujuan penelitian ini untuk mengetahui kemiringan screw conveyor dengan variasi 10°, 15°, 20° terhadap beban maksimum, dan mengetahui besarnya beban maksimum akibat pengaruh sudut kemiringan. Manfaatnya, memahami bagaimana pengaruh sudut kemiringan screw conveyor dengan 10°, 15°, 20°. Berdasarkan hasil analisis dan perhitungan besarnya kapasitas screw conveyor dan beban maksimum di PT. X diperoleh besar kapasitas screw conveyor dengan variasi 10° menghasilkan kapasitas 15,1 ton/jam pada variasi 15° menghasilkan kapasitas 13,2 ton/jam dan variasi 20° menghasilkan kapasitas 12,2 ton/jam.
