Abstract

Limbah batang tembakau mengandung selulosa yang berpotensi menjadi bahan bakar alternatif berupa bioetanol. bertujuan untuk mendapatkan karakteristik nyala api bioetanol limbah batang tembakau. Penelitian dilakukan dengan metode eksperimen. Batang tembakau yang digunakan adalah jenis Na Oogst dan Voor Oogst yang didapat dari daerah kabupaten Jember. Batang tembakau dikeringkan dan diolah menjadi serbuk berukuran random 8 mm – 10 mm, ≤ 0,26-1,19 mm dan 0,25 mm. Serbuk selanjutnya diproses delignifikasi, fermentasi dan distilasi. Produk bioetanol diukur massa jenis dan titik didihnya. Pengujian nyala api dilakukan dengan membakar 1 ml bioetanol dengan pemantikan api. Nyala api diamati dengan kamera dan dilakukan pengukuran durasi nyala menggunakan stopwatch. Hasil pengamatan diolah menggunakan aplikasi ImageJ untuk mendapatkan luas nyala api, dan prosentase warna api merah, kuning dan biru. Hasil penelitian menunjukkan adanya perbedaan produk dan karakteristik nyala api bioetanol berdasarkan 2 jenis tembakau yang digunakan

Abstract

Picco-hydro Power Plant (PLTPH) is a power plant that utilizes water energy to produce small-scale electricity. The power produced starts from tens of watts to 5 Kw. In this study, an economical PLTPH system was designed with the selection of the type of generator according to the mechanical power of the turbine. Turbine mechanical power measured an average of 150-280 Watt with the highest rotation of 135 RPM. Then choose a 300 Watt DC generator with a working ratio of 100-900 RPM. With the selection of cheap after market pulleys and analysis of the size of the transmission ratio, obtained a rotation ratio that can increase the turbine speed up to 810 RPM speed. Then a control panel and simple instruments were made as an electrical stabilizer, protection and measurement of the work of the generating unit. The power generated can turn on 16 DC lamps that have been installed on the lake road, with an optimal power reading of ±31 Watt. If turned on without loading the generator is capable of producing a voltage of up to 44 Volt DC.

Abstract

Several engineering companies in Indonesia still use conventional type machines which, when viewed from the point of view of maintenance, repair, and performance, are still far behind. More than that, we use automatic machines. The first step in this research is to find some related literature that supports it. Then observe the machine that roughly corresponds to the shape of the design later. Then make the design of the electric plate roll machine design. After the design is understood, then plan the equations needed in the analysis of this research. If it is known the equation that will be made when the data is obtained, it can be calculated immediately. The calculation is not adequate, there may be improper equation planning. The final step is when the calculation is done, the conclusion can be determined immediately. Based on the stages of the design process for the automatic system aluminum plate roller machine, several conclusions can be drawn for this final project, including for the roller machine itself using an asymmetric plate roller type with two high mill roll arrangements because this type of machine is the most popular plate roll machine simple

Abstract

The drill machining process requires the drill chuck shank as a coupler between the drill chuck and the drilling machine spindle. Limited availability of drill chuck shank especially for coordinate drilling machine 22 STA is the problem faced. The purpose of the design is to get a replacement of drill chuck shank because on the market that thing is difficult to obtain. The design methods include: the design of special device for placing the drill chuck shank in parallel position to the horizontal axis that is drilling jig with adjustable v-block to adjust the taper of the shank,machining a drilling jig with adjustable v-block, and trial drilling of eight holes on body of drill chuck shank. The real result obtained is drilling jig with adjustable v-block which can be used to make eight holes on body of drill chuck shank coordinate drilling machine 22 STA.

Abstract

3Dmortar printer is a combination of digital automation technology with cement mortar material technology. The problem that appears in 3Dmortar printer technology requires high financial investment, because this is in the process of development especially in Indonesian, this is to build a 3Dmortar printer machine with a focus on mechanical systems that can function optimally. Design of a 3Dprinter machine with a scale of 1x1x1m was successfully made with the Certasian type which has XYZ axes and has a machine weight of 84kg, can be travel speeds above 25mm/s, the frame used is steel with 40mm and 65mm right angle profiles. The supporting such as an extruder feeder as the regulator of mortar output is a 25mm of diameter nozzle with a 40mm of diameter screw thrust system. Mortar pump as a mortar supplier to an extruder with a hopper capacity of 30kg mortar mix with a 40mm of diameter screw drives the system at 68rpm, output can be obtained at the speed 1070gr/minute
