Abstract

Pertandingan Boccia adalah salah satu olahraga paralimpiade yang paling cepat berkembang. Olahraga boccia dibedakan berdasarkan tujuan kompetisi yang bergantung pada kemampuan disik dan fungsionalnya. Atlet boccia diklasifikasikan di salah satu dari empat kelas: BC1, BC2, BC3, atauBC4. Kelas atlet BC3 ditujukan untuk atlet dengan disfungsi lokomotor yang sangat parah di keempatekstremitas,sehinggamereka membutuhkan bantuan dari asisten dan alat bantu. Saat ini, Boccia National Paralympic Committee (NPC) Surakarta memerlukan pengembangan alat penunjang pada olahragabocciaklasifikasiBC3yaitupadahelmbertongkatpointer.Helmbocciayangtersediadipasaran harganya cukup mahal dan masih  mempunyai tingkat akurasi yang rendah dengan standar keamanan dan kenyamanan atlet yang belumterpenuhi. Sehingga dapat memengaruhi keselamatan maupun hasil akhir olahraga boccia. Helm boccia ini berfungsi untuk membantuatlet dalam mengarahkan, membidikarahsasaranbola, dan menggulirkan bola. Berdasarkan pemaparan diatas maka muncul sebuah gagasan untuk membuat produk helmbertongkat dengan akurasi dan standar keamanan yang memadai serta dengan harga yang terjangkau. Kata Kunci : Boccia BC3, Alat Bantu Olahraga Boccia, Helm BocciaPertandingan Boccia adalah salah satu olahraga paralimpiade yang paling cepat berkembang.

Abstract

The lack of rainfall and the absence of catchment areas are the main factors of the lack of water in Puron Village. Making biopori becomes solutive because it is useful for water absorption, reducing standing water, composting containers, and fertilizing the soil. Artificial biopores are made by making holes in the ground using tools such as crowbars or using ground drilling machines. The use of aids model adapted to the drill bit based on the state of the soil contour. This research is focused on classifying drill bits and redesigning which is in accordance with the condition of the soil environment in Puron Village, Bulu District, Sukoharjo Regency. So that biopori holes can be created more effectively and efficiently. The research method was carried out through the classification of tool drill bits through the house of quality product (HOQ) and redesign using Autodesk Fusion 360 software application. It was found that the design with a screw drill model with a pointed spiral has a high product quality value and can applied in puron Village. The design of the drill bit by adjusting the contours of the Puron Village can make a 100 mm diameter biopori hole. The design specifications of the drill bit with steel cast with 12 spiral plates with a length of 1300 mm with a diameter of 115 mm can be driven with a 10 HP engine. The design results have maximum stress, displacement, reaction force and strain of 3.62 MPa, 0.00081 mm, 0.35 N, and 0.000015.

Abstract

The placement of outdoor fitness equipment at tourist attractions is one of the attractions for tourists. Besides that, it can also be used as a means of health socialization for the community in public places. The elliptical trainer type air walker is a popular fitness tool because it is easy to use and has a small risk of injury. Elliptical trainer has a working principle like a walking person where movement is influenced by the force of the hand and leg movements. The design of an elliptical trainer fitness equipment that will be placed in a public place needs to be done to get a good level of security. This article discusses the design of an elliptical trainer device that is safe to place outdoors. The design process uses the Solidworks 2017a application. The elliptical trainer is divided into 4 parts, namely the main frame, drive shaft, hand handle, and leg handle. The manufacturing process is carried out based on Design Manufacture and Assembly and machinery to reduce the risk of manufacturing failure and make it easier to work on. The result of the elliptical trainer design has dimensions of 2,500 x 1,800 x 1,000 mm. The main frame has a safety factor of 3 with a displacement of 8,524e-7 mm.
