Industrial Needs

The needs for added value of agricultural products is increasing, both in the form of health benefits and of reducing pollution waste. The sorting-out fruits that are just wasted can still be used as materials that have added value. In general, fruits contain glucose which is the basic ingredient in processing of bioethanol. Even though the quality has decreased, it still contains glucose which can then be fermented into bioethanol or organic fertilizer. Recently, the pharmaceutical and food and beverage industries require a large supply of bioethanol for further processing according to the industrial needs. Meanwhile, agricultural land is increasingly promoting organic farming. The objective of this activity is to produce new products from fruit waste into bioethanol and organic fertilizers that are useful for both the community and the government so that they can be used as the right solution to reduce environmental pollution and create new business opportunities. Bioethanol processing method uses Saccharomyces cerevisiae as a biocatalyst and uses an EM4 activator to produce organic fertilizers. This activity produces an output product in the form of bioethanol 46.78 % and organic fertilizer which contain 1% N.

Working Principle

Dunia otomotif yang semakin berkembang menuntut perubahan agar alat transportasi lebih baik, tidak hanya pada mesinnya yang irit bahan bakar melainkan juga pada tingkat kenyamanan dalam berkendaraan. Salah satunya adalah perubahan pada sistem transmisi. Tujuan dari penelitian Tugas Akhir ini adalah untuk mengetahui prinsip kerja dan pengaruh variasi berat roller CVT (Continuously Varible Transmission) terhadap sepeda motor Yamaha Mio Soul 110 cc. Proses penelitian ini menggunakan metode eksperimental. Penelitian ini melakukan pengujian variasi berat roller menggunakan ukuran 7 gram , 10,5 gram dan 13 gram. Setelah dilakukan penggantian roller diharapkan dapat meningkatkan kinerja dari motor bakar 4 langkah. Metode penelitian yang digunakan adalah metode eksperimen yaitu dengan menahan throttle pada 3000 rpm, setelah stabil kemudian throttle diputar secara perlahan dengan interval 1000 rpm hingga 7000 rpm. Dari hasil analisis pengukuran untuk hasil pengujian variasi roller, jika menggunakan roller yang beratnya 13 gram maka meningkatkan prestasi mesin yaitu torsi 3,2 (Nm) dan mendapatkan daya yang maksimal sebesar 2,34 (kW) pada putaran mesin 7000 rpm, bahan bakar spesifik terbilang irit hanya 0,772 (kg/kWh) dan efisiensi thermal 10,41 (%). Hal ini terjadi karena berat roller mempengaruhi gaya sentrifugal pada pulley primer sehingga semakin berat roller maka mesin pada putaran tinggi ,akan semakin kuat menjepit sabuk V belt. sehingga pada putaran tinggi untuk mentransfer torsi dan daya ke roda belakang lebih besar.Kata Kunci :Performa, Transmisi, CVT, Variasi RollerThe growing automotive world is demanding changes so that transportation is better, not only in the fuel-efficient engine but also in the level of comfort in driving. One of them is a change in the transmission system. The purpose of this final project research is to determine the working principle and the effect of variations in the weight of the CVT (Continuously Variable Transmission) roller on the 110cc Yamaha Mio Soul motorcycle.This research process uses an experimental method. This study tested the variation of roller weight using a size of 7 grams, 10.5 grams and 13 grams. After changing the roller, it is expected to improve the performance of the 4 stroke combustion motor. The research method used is an experimental method by holding the throttle at 3000 rpm, after it is stable then the throttle is rotated slowly at intervals of 1000 rpm to 7000 rpm. From the results of measurement analysis for the results of roller variation testing, if using a roller that weighs 13 grams increases engine performance ie torque of 3.2 (Nm) and gets maximum power of 2.34 (kW) at 7000 rpm engine speed, specific fuel relatively economical only 0.772 (kg/kWh) and thermal efficiency 10.41 (%). This happens because the weight of the roller affects the centrifugal force on the primary pulley so that the heavier the roller, the machine at high speed, the stronger the V belt belt will be clamped. so at high speed to transfer greater torque and power to the rear wheels.

Electron Energy Loss Spectra

The normal method of background subtraction in quantitative EELS analysis involves fitting an expression of the form I=AE-r to an energy window preceding the edge of interest; E is energy loss, A and r are fitting parameters. The calculated fit is then extrapolated under the edge, allowing the required signal to be extracted. In the case where the characteristic energy loss is small (E < 100eV), the background does not approximate to this simple form. One cause of this is multiple scattering. Even if the effects of multiple scattering are removed by deconvolution, it is not clear that the background from the recovered single scattering distribution follows this simple form, and, in any case, deconvolution can introduce artefacts.The above difficulties are particularly severe in the case of Al-Li alloys, where the Li K edge at ~52eV overlaps the Al L2,3 edge at ~72eV, and sharp plasmon peaks occur at intervals of ~15eV in the low loss region. An alternative background fitting technique, based on the work of Zanchi et al, has been tested on spectra taken from pure Al films, with a view to extending the analysis to Al-Li alloys.
