The use of environmentally friendly stoves in the household sector can be an alternative to overcome the limited use of kerosene and the constrained supply of LPG. The purpose of the study was to develop a gasification stove design with the concept of Top Lith Up Draft on several variations of the column, namely without columns, column 2 holes and column 4 holes using cashew shell fuel which produces optimal gas fuel. The research method is the Top Lith Up Draft method, which is a gasification process semi-gasifier technology method that can produce fewer emissions that can harm human health. The results obtained indicate that the development of the TLUD gasification stove design from several variations of the column functions well. The gasification testing process carried out for the three variations of the column used resulted in good temperature values, namely for variations without a temperature column of 829 , column 2 holes of 935 , and column 4 holes of 934 . The best column variation is the 2 hole column with the highest temperature value of 935. Kata kunci: Gasification, TLUD, cashew shell, efficiency.

In the face of the depletion of fossil fuels, alternative fuels such as biomass are needed. However, biomass has a fairly low calorific value and several other disadvantages compared to petroleum. Therefore, a new breakthrough is needed to correct these weaknesses, one of which is the Torrefaction process. The purpose of this study was to determine the effect of torrefaction of coconut shell and cashew shell biomass on the physical and chemical properties of the material. This research was conducted using coconut shells and cashew shells. The results of this study indicate that the calorific value of coconut shells and cashew shells after torrefaction is 5115,297-5147,021 cal/gr. The water content in coconut shells is 2.718% and the value of water content in cashew shells is 2.397%, the ash content of coconut shells is 6.853% and the value of cashew shell ash content is 6.600%, the value of volatile levels of coconut shells is 14.885% and the value of volatile levels of cashew shells of 14.557% and the value of fixed carbon content of coconut shell is 75.574% and the value of fixed carbon content of cashew shell is 76.447%.

Industri rumah tangga merupakan salah satu jenis industri yang mudah dilakukan dan tidak membutuhkan modal besar. Dibutuhkan suatu alat penunjang dalam menjalankan usaha rumah tangga agar usaha tersebut dapat berjalan dengan baik. Penelitian ini dilakukan untuk mengetahui desain mesin, daya motor dan sistem kerja mesin spiner untuk industri rumah tangga tersebut. Hasil perancangan menunjukkan bahwa rancangan mesin spinner vertikal yang dibuat dapat beroperasi dengan baik dalam penirisan singkong parut dan kelapa parut dengan menggunakan motor listrik. Perancangan mesin spinner peniris vertikel yang dibuat memiliki tiga variasi kecepatan yaitu kecepatan I (1410 RPM), kecepatan II (1461 RPM) dan kecepatan III (1471 RPM). Pengujian alat dilakukan sebanyak tiga kali yaitu dalam waktu 5 menit, 10 menit dan 15 menit. Pengurangan massa bahan pada menit ke 10 hingga 15 cenderung lebih sedikit dimasing-masing kecepatan. Dari penelitian ini dapat disimpulkan bahwa penirisan pada singkong parut lebih efektif dilakukan di kecepatan ke III dengan waktu 10 menit dan massa yang tersisa sebesar 1,399 kg. Sedangkan hubungan antara waktu terhadap massa kelapa menghasilkan pengurangan massa bahan terbesar terjadi di 5 menit awal disetiap kecepatan. Sedangkan pengurangan massa pada menit ke 10 hingga 15 cenderung lebih sedikit pada masing-masing kecepatan. Dapat disimpulkan bahwa penirisan pada kelapa parut lebih efektif dilakukan di kecepatan ke III dengan waktu 15 menit dan massa yang tersisa sebesar 1,232 kg.

Every year the use of fossil fuels has increased, which requires finding alternative energy sources to replace fossil fuels. The existence of plastic waste, especially HDPE plastic and rice husks, is a potential to be used as renewable energy in the form of briquettes. This research was conducted to determine the potential use of plastic powder and biomass as an alternative fuel. The biomass used in this research is rice husk and HDPE plastic. To determine the quality of briquettes, several variations of the mixture of rice husks were used, namely: sample 1 = 90% rice husk + 10% High Density Polyethylene (HDPE) plastic, sample 2 = 80% rice husk + 20% High Density Polyethylene (HDPE) plastic, sample 3 = 70% rice husk + High Density Polyethylene (HDPE) plastic 30%, sample 4 = 100% rice husk. The test parameters used are proximate test (calorific value), flame length test, briquette resistance test. The test results obtained briquettes in sample 3 have a calorific value of 7586,853 cal/g and have a combustion rate value of 0,83 grams/minute.Keywords: Briquettes, Rice Husk, High Density Polyethylene (HDPE) Plastic, Calorific Value

Regarding the conversion system with a thermoelectric element which allows it to be used anytime and anywhere, that's why you need to position the tool correctly. With that, the research aims to find out the voltage produced and the performance of thermoelectrics as a generator of electrical energy. The method used in this research is a system for converting briquette heat energy into electrical energy. The variations in the research experiment are fan cooling 1, fan cooling 2 and water cooling. By using a charcoal briquette heater and three variations of cooling, the average voltage of cooling fan 1 0.660 V, cooling fan 2 0.769 V, water cooling 0.903 V can be produced and the average current of cooling fan 1 is 0.029 A, cooling fan 2 is 0.034 A, cooling Water 0.039 A. The characteristics of the resulting temperature difference show a significant increase along with the length of combustion time. The resulting voltage is higher if the hot combustion of the briquettes is carried out with a variation of water cooling. Keywords: Briquettes, electricity, hot side, thermoelectric, and voltage

Air pollution is caused by the activities of motorized vehicles that emit exhaust gas emissions, including CO, CO2, HC, NOX, SOX, and particulates. The purpose of this study was to determine how the effect of fuel variations on the time of fuel consumption and exhaust emissions on motorcycles and to find out how the composition of mixing premium fuel with ethanol affects the time of fuel consumption and exhaust emissions. This study uses 4 types of fuel, namely premium, pertalite, E-5, and E-10 and tested using 3 variations of throttle openings. From the test results, it is found that the most fuel consumption is found in the wide throttle opening on premium fuel = 0.77 L/h. For the results of the lowest CO and HC exhaust emissions found in the wide throttle opening on the E-10 fuel where the emission value of CO = 1.98% and HC = 1425 ppm. So it can be concluded that in comparison with the time of fuel consumption, the higher the throttle opening, the faster the fuel consumption will be and for exhaust gas emissions, the higher the throttle opening, the lower the CO and HC emission values. Mixing premium fuel with ethanol can make the fuel consumption time slower than pure premium and can also reduce the content of CO and HC exhaust emissions.Key words: Fuel, Exhaust emissions, Fuel consumption

Cassava skin is a waste of high-carbohydrate cassava that can be treated asa an alternative fuel source. As for the purpose of this study, it is to know how to produce bioethanol from cassava skin and how much ethanol is produced in the fermentation destilation procwss. Bioethanol research from the cassava skin is made by means of a fermentation process using a 9 and 12 day fariation with a 20,4 and 60 gram supplement of a mixture (leaven/yeast) of a 20,4 and 60 gram that is cut off by sample destilting devices. Research shows that the longer the fermentation from a mixture of refined caskbark and yeasts does not significantly affect the ethanol produced, since ethanol results from each fariation is 10%. Key words: Cassava suede, fermentation, bioethanol, renewable energy
