Alternative fuel will be one of the solutions for resolving energy crisis that happening now. Methanol gel is one of them that have lot of benefits. In this paper will be discussing how to increase quality of methanol gel. The quality that we pursue is to decrease number of explosion when the process of incineration was executed. Only four factors observed in this study, include; using purple dye, number of NCl volume, number of layer, and using water as raw material. Experiment method used in this study was Taguchi Method with L8 orthogonal array and twice repetitions. The results that we get were quite surprising. Using ANOVA with 95% level of confidence as analyzer the results, show us that the influencing factors for methanol gel quality were using purple dye, number of layer, and using water.

Isolasi thermal merupakan metode atau proses yang digunakana untuk mengurangi laju perpindahan panas. Konstruksi instalasi pipa air panas, bahan pipa dan bahan isolasi yang digunakan akan menentukan kualitas aliranfluida kerja. Instalasi suatu isolasi pada alat uji aliran fluida dalam pipa air panas merupakan komponen utama dalam menjaga dan mendapatkan kesetabilan aliran panas fluida yang dibutuhkan. Aliran yang terdapat pada pipa saatpengujian adalah aliran laminar dan turbulen. Uap panas merupakan sumber utama dalam mengolah produksi, aliran pipa uap panas selalu dipengaruhi udara bebas, karena itu harus dilakukan pemilihan bahan isolasi yang sesuaispesifikasi yang dibutuhkan dalam rangka mendapatkan fungsi yang efektif dan efisien dalam menjaga dan mempertahankan panas pada pipa air panas. Untuk menentukan bahan yang paling tepat dalam mengurangi kehilangan panas pada pipa air panas, analisa dilakukan dengan menghitung jumlah kehilangan panas tanpa menggunakan bahan isolasi dan menggunakan isolasi dengan ketebalan bervariabel yaitu dengan ketebalan 10 mm dan 12 mm. Proses analisa dilakukan pada suhu tertentu yang dibutuhkan yaitu 50°C, 60°C dan 70°C.

The 3D printers process is applied to create prototype components, but at the last 3D Printers are often applied as last products. So, high accuracy is required in this case. In this research will find the optimalsetting of the dimensional accuracy 3D printers based fused deposition modeling. The method used isthe Taguchi method, the reason for using this method its efficiency, this is because the OrthogonalArray matrix requires less number of experiments than the classical experimental design. Analysis ofVariance is also needed in this method to see the factors that significantly influence the responsevariable. The results of this study indicate that the factors that significantly influence is printspeed bycontributing 53.08%, flowrate contributes 16.4%, and temperature heater block contributes 3.85% andoptimal setting is temperature heater block 190º, print speed 60mm/s and flowrate 6.28 mm3/s.

Salah satu upaya mengurangi kerugian akibat berhentinya proses produksi clinker/cement secara mendadak akibat kerusakan alat adalah memonitor kondisi peralatan secara terus menerus. Suspention preheater fan adalah salah satu peralatan yang sangat vital pada proses pembuatan clinker dimana salah satu komponennya adalah bearing. Untuk memantau kondisi bearing selama beroperasi maka di pasang peralatan pemantau getaran dan temperatur yang digunakan untuk memantau amplitudo getaran dan temperatur bearing. Berdasarkan hasil pengamatan, amplitudo getaran bearing yang nilainya dibawah 4,5 mm/s dan temperatur dibawah 700 menunjukan kondisi bearing yang masih dalam batas aman untuk beroperai. Sedangkan nilai amplitudo getaran yang mencapai 8,7mm/s dan temperatur 1200C menunjukan kondisi bearing yang sudah tidak aman untuk beroperasi. pada kondisi ini di dapati bearing rusak dan harus diganti. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa ketika terjadi kerusakan pada bearing besar getaran pada mesin SP Fan melonjak hingga melebihi batas aman dan pada saat bersamaan juga terjadi lonjakan temperatur. Terdapat hubungan antara nilai getaran dan temperatur yang disebabkan oleh gesekan antar komponen dalam bearing

The blade turbine is a component that experiences a very high stress on a wind turbine. Materialsoften used are aluminum composite, polymer and even steel. Aluminum has a high fatigue. Plasticis very suitable But it requires mold while steel has a great weight. Wood is an alternative materialfor a blade turbine. Because it is lightweight, strong, easily shaped, and has high fatique resistanceand is easy to obtain. In this research, a stress analysis on a blade with balsa wood material withfixed force 5 Newton is applied. The result of analysis by using Autodesk Inventor student version,shows that the minimum Stress that occurs is: 12.1265 N / m ^ 2 and the maximum stress is:955595 N / m ^ 2. The maximum stress occurs at the point / node 390 or the area near theassembly hub or fixed geometry marked in red.
