Abstract

The sun is the primary source of energy on the earth, but its light sometimes cause thermal discomfort for humans. The thermal engineering started one in the automotive sector in particular car is to install the air conditioner to lower the temperature of the cabin and use the tranfer window film to block sun light intensity. Testing the proper use of window film to determine the effect of inhibition of the ability to transfer the glass clarity of light intensity on the glass needs to be done to determine what percentage inhibition that has the intensity and the lower the cabin temperature, so the thermal comfort is achieved faster. From the results of the testing were conditioned using Solar ray Collector © PHYWE Systeme GmbH CO.KG. Inhibition obtained with 40% glass has an intensity of 39% and a temperature of 63.20 C, the glass has an intensity of 60% inhibition of 21% and a temperature of 61.90 C, the glass has an intensity of 80% inhibition of 8% and a temperature of 63.80 C. So the use of glass with 60% inhibition is best to accelerate the thermal comfort is achieved.

Abstract

Biodiesel adalah bahan bakar alternatif yang terbarukan dari lemak hewani dan nabati untuk menggantikan minyak solar. Oleh karena pemerintah menetapkan penggunaan campuran biodiesel 30% dalam minyak solar untuk bidang transportasi per Januari 2020, maka penggunaan teknologi ramah lingkungan, berkelanjutan dan ekonomis pada pilot plant biodiesel harus dilakukan untuk meningkatkan mutu serta harga biodiesel sehingga dapat setara dengan minyak solar. Beberapa jenis Teknologi pengolahan biodiesel, diantaranya adalah teknologi tanpa/nir katalis. Teknologi ini cuma membutuhkan bahan baku berupa minyak nabati dan metanol, tidak menggunakan katalis. Penggunaan metanol dalam bentuk uap superheated pada reaksi nir katalis membutuhkan peralatan yang dapat mengubah metanol cair menjadi uap superheated metanol. Konversi methanol menjadi superheated methanol pada penelitian ini dilakukan dengan menggunakan preheater metanol berdasarkan desain dari penelitian terdahulu menggunakan software ChemCAD. yang akan memanaskan metanol secara tidak langsung melalui fluida pemanas berupa thermal oil Mobiltherm 605, untuk mendapatkan uap metanol dari preheater metanol yang memenuhi syarat penggunaan yang tepat

Abstract

Matahari adalah sumber energi yang utama di bumi, namun paparannya kadangkala menimbulkan ketidak nyamanan termal bagi manusia. Rekayasa termalpun dilakukan salah satunya di sektor otomotif khususnya mobil yaitu dengan memasang alat pengkondisian udara untuk menurunkan temperatur kabin dan menggunakan kaca film untuk menghambat tranfer intensitas cahaya matahari. Pengujian penggunaan kaca film yang tepat untuk mengetahui Pengaruh Penghambatan Kebeningan Kaca Terhadap Kondisi Intensitas Cahaya Dan Panas Radiasi Dalam Ruang Kaca, tranfer intensitas cahaya pada kaca perlu dilakukan untuk mengetahui penghambatan berapa persenkah yang memiliki intensitas dan temperatur kabin paling rendah, sehingga kenyamanan termal lebih cepat tercapai. Dari hasil pengujian yang dikondisikan menggunakan Solar ray Collector Hasil Rancangan. didapat kaca 40% intensitas 65% temperatur 173,66%, kaca 60% intensitas 59% temperatur 168,79%, kaca 80% intensitas 56% temperatur 179,78%. Maka penggunaan kaca 60% adalah terbaik untuk mempercepat kenyamanan termal tercapai

Abstract

Today's technological growth is very rapid, companies continue to develop in technological innovation in their products. At the same time, it is necessary to increase adequate energy such as electric power, chemical power, and renewable alternative fuels to replace diesel oil, namely Biodiesel. As of January 2020, the government has implemented a fuel mixture for the transportation sector containing 30% biodiesel in diesel oil. There are many types of biodiesel processing technologies, including non-catalyst technology. This technology only requires raw materials in the form of oil and methanol, without using a catalyst. The use of methanol in the form of superheated vapor in a non-catalyzed response requires equipment that can replace liquid methanol into superheated methanol vapor. The conversion of methanol to superheated methanol in this research was carried out using a methanol preheater based on a design from previous research using the ChemCAD application. namely heating methanol indirectly through a heating fluid in the form of Mobiltherm 605 thermal oil. With mobiltherm hot at a temperature of 50ºC, the pump performance results are obtained with Capacity (Q) 0.0003 m^3/s, Head (H) 0.019 m, Power hydraulic (N_h) 119 watts, and efficiency (η) 95.2%. The greater the value of the density of the fluid, the greater the power used. In the case of Mobiltherm, which has a different fluid viscosity from water, the hydraulic power and efficiency obtained are also high. The mobiltherm 605 heat transfer rate is 35% through the double pipe annulus and the methanol temperature rate through the double pipe inner pipe

Abstract

Bioethanol is a clean fuel, renewable energy source that can be used in place of fossil fuels. Bioethanol has similar characteristics to gasoline fuel, making it an excellent alternative fuel for SI engines, contributing to the reduction of air pollution, the increased use of biofuels, and the removal of fossil fuel consumption. Analysis of the SI engine performance using gasoline fuel with an octane rating of 90 and gasoline-bioethanol blends containing up to 20% bioethanol concentration, each fuel blended at 5% by volume fraction. The purpose of this study is to present the experimental results for a spark ignition (SI) engine with a single injector that operates by using a gasoline-bioethanol blend as fuel. Analysis of the SI engine performance by using gasoline fuel with an octane rating of 90 and gasoline-bioethanol blends containing up to 20% bioethanol concentration. Each fuel was blended with bioethanol at an interval of 5% by volume fraction. The test was conducted on an SI engine with a capacity of 1500 cc, four cylinders, and a single injector was used to distribute fuel to each cylinder through the intake manifold. The shaft of the engine is connected to a 75 kW of eddy current dynamometer shaft to measure the engine torque. The engine load is controlled using an interface computer system. Load on an engine is done by increasing braking on the dynamometer, and real-time signals from the sensors are recorded. Each fuel sample is operated at full load or wide-open throttle (WOT) at speeds ranging from 1000 to 5500 revolutions per minute (rpm). The experiments show that adding bioethanol to gasoline fuel can have a significant effect on the single injector SI engine performance. When the bioethanol concentration of 10% (E10) by volume is used, it is possible to maintain engine power with lower fuel consumption or lower the energy supply to the engine cylinder, thereby increasing the thermal efficiency of the single-injector SI engine by 6.33% compared to gasoline fuel.
