Perancangan alat ini adalah hasil observasi dan studi literatur di kabupaten Tanah Laut yaitu pada limbah pabrik penggilingan padi (Dedak), jagung, dan ikan laut yang sudah rusak dari nelayan jumlahnya melipah. Hampir setiap hari limbah tersebut ada, akan tetapi masih belum banyak dimanfaatkan secara optimal oleh peternak maupun masyarakat sekitar. Khususnya sebagai pakan ternak alternatif, karena belum adanya penggunaan mesin pencetak pelet apung dari bahan dedak, jagung, dan ikan laut yang sudah rusak dari nelayan. Biasanya mesin ini hanya digunakan dalam pencetakan pelet dari bahan dedak halus dan frementasi yang telah dirancang khusus untuk membuat pakan ternak. Perancangan ini dilakukan untuk untuk memebuat alat pencetak pelet dari dedak, jagung, dan ikan laut yang sudah rusak dari nelayan beserta menghitung kapasitas produksinya. Hasil perancangan menggunakan motor diesel 24 PK/HP 2.200 rpm, pompa pendingin ¾ inci, tangki pendingin dengan panjang 1 m/180 liter, menghasilkan kapasitas 75-100 kg/jam. Kata kunci: dedak, jagung, ikan rucah, mesin pencetak pelet
Sistem rem adalah komponen yang ada pada mobil termasuk keamanan dalam berkendara. Untuk keamanan pengendara maka harus dibutuhkan sistem pengereman yang optimal. Perawatan minyak rem dilakukan dengan cara pengecekan minyak rem. Jika minyak rem habis maka minyak rem diganti. Untuk mempermudah pengisian minyak rem maka dibuatlah Alat pengisian minyak rem secara otomatis agar memudahkan saat pengisian minyak rem. Tujuan penelitian ini yaitu untuk mengetahui cara kerja kelistrikan pada alat pengisian minyak rem dan mengetahui Tegangan Baterai, Tegangan Motor, Arus Motor dan Volume minyak rem. Alat ini mempunyai sistem kelistrikan dan rangkaian sistem kelistrikan alat pengisian minyak rem otomatis berawal dari baterai menuju ke Fuse lalu ke Switch terus ke Potensiometer sprayer terus ke motor Washer. Adapun pengukuran pada alat pengisian minyak rem yaitu mengukur Tegangan, Arus, dan Volume. Dari hasil pengukuran Tegangan, Arus danVolume keluarnya minyak rem yang di lakukan sebanyak tiga kali pengukuran di dapat nilai rata rata yaitu pengukuran tegangan batrai nilai rata ratanya 12,41 V. Tegangan Motor nilai rata-ratanya yaitu 10,7 V. Arus Motor nilai rata-ratanya yaitu 0,57 danVolume keluarnya minyak rem niai rata-ratanya yaitu 40,25 ml/s. Pengisian minyak rem yang lebih optimal yaitu dilakukan pada putaran potensiometer keempat karena diputaran keempat volume keluarnya minyak rem lebih cepat.
Although Palm Oil Mill Effluent (POME) can be used as a raw material for biodiesel production, the POME contains an excessive amount of Free Fatty Acids (FFA), necessitating a preliminary process and esterification. POME is degummed using phosphate acid and bleached with carbon active. Additionally, this study used KOH-impregnated zeolite to reduce FFA. The purpose of this study is to determine the effect of adding impregnated zeolite on esterification. POME was heated to 600C for 30 minutes, then degumming with 3 % of phosphate acid for 30 minutes, followed by bleaching with carbon active with a comparison ratio of 8:3 at 1000C for 1 hour, and finally, esterification with 3 percent impregnated zeolite from the POME weight at 600C for 4 hours. The analysis was conducted using titration methods to determine the FFA of each esterification. The data will be compared between zeolite and non-zeolite degumming, bleaching, and esterification. The results indicated that the most effective method for reducing FFA was degumming, bleaching, and esterification with zeolite.
Fuel oil (BBM) is a type of non-renewable fuel so that its availability will eventually run out, to overcome this it is necessary to conduct research that can use environmentally friendly energy, one of which is electricity. In recent years, the development of electric power-based vehicles has increased rapidly, both for lighting, transportation, and so on. Electric bicycles are an example of a means of transportation that uses electricity and is environmentally friendly. This bicycle can be used by anyone and can be taken anywhere besides being relatively inexpensive, making it an effective, efficient and environmentally friendly means of transportation. The bicycle propulsion system uses a BLDC electric motor which is controlled by the ECU and throtle. Where electrical energy is stored first in a battery/battery and then flowed to the BLDC electric dynamo so that the bicycle wheels can rotate. Based on research results, electric bicycles can travel at a maximum speed of 22.22 km/hour
Transport is one of the main community needs, but along with the increasing number of transport such as motorcycles and increasing also use of fuel oil.While fuel oil are currently derived from fossil where is not sustainable, alternative fuel can use water as fuel, by the process elektrolysis. Water is a compound composed of hydrogen and oxygen, both compound this is a flammable that can be used as alternative fuel or known as gas HHO . When used alternative fuel, gas HHO used along with fuel oil (bi-fuel) .This research discussed of the use of a generator HHO (tool gas producer HHO) on a motorcycle to a variation with an electrolyte namely fresh water, sea water and aquadesh in order to know some of the form a generator HHO that is the generator, the rate of the production of gas and efficiency of gas. This research obtained the best grades HHO power generator at 6.01 watts , the rate of the production of gas by 0.015 and efficiency as much as 1,265 when using aquades. Keywords: HHO, HHO generator, electrolysis
