Emisi gas hasil pembakaran bahan bakar fosil secara teoritis mengandung polutan emisi gas yang terdiri dari gas-gas COx, NOx, HC, Ox, SO2 dan logam-logam berat. Pembakaran bahan bakar fosil pada sektor transportasi berkontribusi paling besar terhadap polusi yang dihasilkan oleh emisi gas buang mesin otomotif. Oleh karena itu perlu dilakukan penanganan yang tepat terhadap emisi gas mesin otomotif ini. Hal ini telah dirancang bentuk geometris alat yang berfungsi sebagai media adsorbsi emisi gas mesin otomotif yang disebut bed reactor (BR). Bentuk geometris dari BR dirancang merujuk kepada bentuk geometris dari knalpot (muffler) kenderaan mobil mini bus. BR yang dirancang terdiri dari 2 (dua) jenis BR yaitu jenis aliran laminar dan aliran turbulen. Bentuk geometris BR, berbentuk penampang elips dengan sumbu mayor = 192 mm, sumbu minor = 125 mm, dan panjang muffler = 320 mm, untuk jenis aliran laminar. Sedangkan BR jenis aliran turbulen berbentuk penampang elips dengan sumbu mayor 192 mm dan sumbu minor 125 mm, dan panjang muffler L = 350 mm. Daya adsorbsi BR telah diuji dengan bantuan alat uji emisi gas jenis anycar autochek gas & smoke versi 1.5.1.E-1. Daya adsorbsi BR maksimum untuk jenis aliran laminar terhadap gas CO2 = 47,76 % dan untuk aliran turbulen CO = 42,72 % & gas HC = 35,40 %, masing-masing BR diisi zeolit alam dengan besar butir 10 mesh.","PeriodicalId":102197,"journal":{"name":"JOURNAL OF MECHANICAL ENGINEERING MANUFACTURES MATERIALS AND ENERGY","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127645660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process of drying red onion is one of the important factors in producing the best quality of red onion. Environmentally friendly and easy operation and maintenance technology is the desired technology. In the process of engine design, the strength of the material and structure are the main factors of the building of the machine. Calculation with finite element method (FEM) is the best choice to obtain information on stress distribution on a machine structure. In this study, the calculation of the FEM method was assisted by Ansys APDL 15.0 software. The objectives of this study were: (1) calculation of the load on the tray structure, (2) the distribution of stress on the tray structure, seat, and frame for red onion dryers, and (3) analyzing the strength of the material using the Tresca and Energy Distortion methods. The input load comes from the weight of the tray and red onion. The analytical method used is the finite element method with the type of structural analysis and Beam 3Node 189 element type. Based on the FEM simulation results, the maximum stress that occurs in the tray is 1.22 MPa and the maximum deflection is 0.0055 mm. The maximum stress in the tray support structure is 33.25 MPa and the maximum deflection is 0.014 mm. The maximum stress on the frame structure of the onion drying machine is 0.89 MPa and the maximum deflection is 0.000235 mm which occurs in the middle of the machine structure. Using the Tresca and Distortion Energy theories, it is found that the stresses that occur are still far from the failure criteria for all structures. Likewise, the deflection that occurs is very small so that the construction of the onion drying machine is safe to use.","PeriodicalId":102197,"journal":{"name":"JOURNAL OF MECHANICAL ENGINEERING MANUFACTURES MATERIALS AND ENERGY","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131167946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beton busa merupakan jenis beton ringan yang menggunakan foam dan serat TKKS sebagai agregat ringannya. Beton busa telah diteliti dan dikembangkan menjadi berbagai produk bangunan ringan, salah satunya ialah genteng ringan. Fenomena hujan es dapat merusak pesawat, mobil, dan tentu saja atap rumah. Penelitian ini bertujuan untuk menganalisa respon mekanik produk genteng dari material komposit beton busa diperkuat serat TKKS akibat beban impak yang diakibatkan hujan es. Untuk memverifikasi hasil pengukuran, dilakukan pula simulasi beban impak menggunakan software Ansys. Pengujian impak hail (hujan es), dilakukan menggunakan alat uji kompresor impak (KOMPAK) dengan batang aluminium sebagai impactor-nya. Pengukuran tegangan pada spesimen diukur dengan menggunakan strain gages untuk beton. Pengujian divariasikan dengan jarak impak striker dan impactor. Dari penelitian ini diperoleh hasil bahwa produk genteng tidak mengalami kegagalan hingga kecepatan impak 14 m/detik. Pada jarak impak 60 mm (kecepatan impak 16,09 m/detik) genteng mulai mengalami kerusakan, dengan tegangan yang terukur pada strain gage sebesar 1,07 MPa.
