Abstract

Sepeda adalah solusi untuk menciptakan transportasi yang ramah lingkungan. Karena jarak antara jurusan di ITS cukup jauh, ITS bermaksud membantu transportasi antar jurusan dengan sepeda kampus. Atas dasar tersebut, pada tahun 2014 Laboratorium Perancangan dan Pengembangan Produk telah merancang dan membuat sepeda multigender untuk civitas akademika ITS. Dari hasil uji fungsi menunjukkan sepeda tersebut masih belum stabil dan aman pada saat berbelok. Demikian pula dari hasil uji ergonomi sepeda juga masih kurang nyaman untuk dikendarai, karena dari responden wanita nilai RULAnya masih ada yang 4. Oleh karena itu perlu dilakukan pengembangan sepeda khususnya pada desain rangka yang baru. Langkah- langkah penelitian yang dilakukan adalah evaluasi sepeda multigender yang ada. Dari evaluasi tersebut pada langkah awal dilakukan perubahan geometri rangka, yaitu sudut head tube dari 80° menjadi 74°, dan wheelbase tidak melebihi standar yaitu 1150mm. Selanjutnya dilakukan perubahan profil rangka utama dari bentuk round square menjadi ellips. Hal ini dimaksudkan untuk menambah kekakuan rangka. Setelah itu dilakukan evaluasi resiko cedera pengendara, baik laki- laki maupun perempuan dengan metode RULA (Rapid Upper Limb Assessment) dengan menggunakan software CATIA V5R20. Selanjutnya melakukan analisa kekuatan material, khususnya analisa tegangan yang terjadi pada rangka utama. Kemudian diakhiri dengan langkah membuat gambar detail rancangan sepeda tersebut dengan software CATIA V5R20. iv Hasil dari penelitian ini adalah rancangan sepeda ITS dengan spesifikasi panjang total 1217mm dan tinggi 930mm. Jarak antara wheelbase 1150mm, diameter roda depan dan belakang sama yaitu 670mm. Sudut headtube rangka 74°. Dari analisa ergonomi menunjukkan bahwa nilai dari RULA pria dan wanita adalah 3. Rangka utama sepeda ITS terbuat dari material A ST45 berbentuk elips mampu menahan beban 100kg, dimana tegangan maksimum yang terjadi dari hasil analisa dengan menggunakan software CATIA V5R20 sebesar 57,8 MPa, lebih kecil daripada tegangan ijin material A ST45 sebesar 60MPa. Kemudian didapatkan perancangan proses manufaktur dan perakitan rangka, serta perakitan rancangan sepeda. ================================================================================================== The bike is the solution to creating an environmentally friendly transport. Because the distance between the departments in ITS far enough away, ITS meant to help transportation between campus by bicycle Department. On the basis of the aforementioned, in 2014 the laboratory design and product development have been designing and making the bike multigender for civitas academica ITS. From the results of the test function demonstrates the bike is still not stable and secure at the time of the turn. Similarly, the results of the test bike ergonomics are also less comfortable to drive, because of the respondents women RULA value there is 4. Therefore it needs to be done especially on the design of bicycle development order a new one. The steps research done is a bicycle evaluation multigender. The evaluation of the first step done change the geometry of the frame, i.e., the angle of the head tube of 80° to 74°, and becomes a wheelbase not exceeding the standard IE 1150mm. next conducted major order of profile changes the shape of the round square became the ellips. It is intended to increase the stiffness of the frame. After it's done an evaluation of the risk of injury to riders, both men and women with RULA methods (Rapid Upper Limb Assessment) using the software CATIA V5R20. Further analysis of strength of materials, in particular the analysis of voltage that occurs in the main frame. Then ends with steps to make the bike design detail images with software CATIA V5R20. vi The results of this research is the design of the bike with ITS specifications total length 1217mm and high 930mm. The distance between the 1150mm wheelbase, front and rear wheel diameter is the same i.e. 670mm. 74° headtube Angle order. Analysis of ergonomics showed that the value of RULA men and women is 3. The main bike frame ITS made of material with elliptical A ST45 is able to withstand a load of 100 kg, where the maximum voltage that occurs from the results of the analysis using the software CATIA V5R20 of average 57,8 MPa, smaller than the tension of the material permits A ST45 of 60MPa. Then obtained the manufacturing and Assembly process design framework, as well as Assembly design of the bike.
