Abstract

Two different turbulence models, i.e. Spalart Allmaras (SA) and Reynolds stress model (RSM) are used as turbulence model in the cyclone investigation via numerical simulation. The appropriate turbulence model is key parameter on the analysis of cyclone performance. The cyclone has a characteristic diameter of 30 cm. Four different inlet gas velocities, i.e. 13.6 m/s, 14.7 m/s, 16.3 m/s, and 17.8 m/s are simulated in FLUENT. It is found that the particle separation efficiency is higher 90% for all inlet gas velocities variation when RSM is used as turbulence model. The pressure drop is increasing linearly with the inlet gas velocity. The utilization of RSM can give better result of efficiency and pressure drop than SA turbulence model.

Bahan baku biogas yang digunakan pada penelitian ini berasal dari kotoran sapi. Pengambilan biogas dilakukan di kelompok ternak sapi Pandan Mulyo, Bantul, Yogyakarta. Generator yang digunakan berkapasitas daya 2.200-Watt dan variasi pembebanan 660, 720, 780, 840, dan 900 Wat. Parameter yang diambil berupa tegangan, arus, putaran mesin, dan debit biogas. Hasil penelitian menunjukkan daya keluaran genset dari 5 variasi pembebanan yaitu 660, 720, 780, 840, dan 900 Watt berturut-turut adalah 599,4; 651; 681,6; 676,5; dan 668,5 Watt. Nilai konsumsi bahan bakar dari 5 variasi pembebanan yaitu 0,645; 0,652; 0,673; 0,680; dan 0,727 kg/jam. Dari 5 variasi pembebanan menunjukkan bahwa unjuk kerja paling optimal dari genset berbahan bakar biogas ini berada pada tingkat pembebanan 660 Watt dengan daya keluaran yang dihasilkan sebesar 599,4 Watt.AbstrakThe performance testing of biogas-fueled generators has not been carried out much.

Abstract

Based Village Law No. 6 of 2014 states legitimacy for village apparatus to organize a government in the village. The quality and quantity of human resources (HR) determine the success rate of government management and programs. The condition of village apparatus that show a low level of professionalism both in creativity, innovation, institutional management becomes a serious problem. The quality of village apparatus human resources that are currently reflected in the services produced in the pandemic era is quite declining, especially the entry of technology systems that require village apparatus to change the service system from manual to system with technology (computer). Such as simple bookkeeping that becomes the main point of recording and reporting every village activity. This community service program aims to provide training and assistance in upgrading simple bookkeeping skills and application use (Ms. Office) in Gembol village. The method of the community service program in the form of assistance to Gembol village devices is by preparing, licensing, socialization of activities, surveys, observation, and mentoring in the form of education, training, and measurement of results. Community service in Gembol village has been carried out successfully. The evaluation results showed the interest of village apparatus in improving the quality of human resources through mentoring and training sustainably. The improvement in training results can be seen from the evaluation that shows the low understanding of village apparatus for simple bookkeeping by Law No. 6 of 2014.

Abstract

Makalah ini menyajikan proses perancangan mesin roller spinning yang digunakan untuk membuat panci dari plat aluminium. Proses perancangan digunakan untuk menentukan dimensi dari komponen penting dari mesin roller spinning dan kebutuhan daya penggeraknya. Proses perancangan melibatkan persamaan-persamaan yang diambil dari beberapa referensi. Hasil dari perancangan ini menampilkan bahwa kebutuhan ukuran baut sambungan flange poros-mandrel minimal berukuran M6 kelas 4.6 berjumlah 8 buah, diameter poros penggerak minimal sebesar 40,54 mm terbuat dari bahan baka AISI 6150. Kebutuhan daya pengerolan bervariasi tergantung dari ketebalan plat dan kecepatan putar motor yang digunakan, semakin tebal plat dan kecepatan motor maka penggunaan daya penggerak semakin besar. Untuk kebutuhan industri mikro disarankan kecepatan putar maksimum sebesar 500 rpm agar kebutuhan daya untuk pengerolan plat tebal 1,5 mm cukup dengan motor listrik berkapasitas 1 HP.

Abstract

AbstrakPenelitian ini bertujuan menguji secara eksperimental pengaruh penggunaan campuran minyak pirolisis dan pertalite pada torsi, tenaga, dan konsumsi bahan bakar motor bensin Honda Beat 110cc. Minyak pirolisis dicampur dengan pertalite dengan persentase volume minyak pirolisis: 0%, 5%, 10%, 20%, dan 30%. Metode yang digunakan dalam penelitian ini adalah menggunakan dynotest tool kit dan fuel consumtion test. Parameter yang diukur adalah nilai torsi, daya, dan konsumsi bahan bakar. Hasil penelitian menunjukkan bahwa pertalite murni menghasilkan torsi dan daya tertinggi dibandingkan dengan variasi campuran pertalite dengan minyak pirolisis lainnya. Hal ini dimungkinkan karena nilai viskositas pertalite lebih rendah dibandingkan dengan variasi lainnya. Konsumsi bahan bakar terendah terdapat pada variasi 70% volume pertalite dan 30% volume minyak pirolisis yang menghasilkan konsumsi bahan bakar sebesar 41,66 km/I.AbstractThis study aims to experimentally test the effect of using a mixture of pyrolysis oil and Pertalite on torque, power and fuel consumption of the 110cc Honda Beat gasoline motor. Pyrolysis oil is mixed with pertalite with the percentage volume of pyrolysis oil: 0%, 5%, 10%, 20%, and 30%. The method used in this study is to use the dynotest tool kit and fuel consumption test. The parameters measured are the value of torque, power and fuel consumption. The results showed that pure pertalite produced the highest torque and power compared to variations of the pertalite mixture with other pyrolysis oils. This is possible because the pertalite viscosity value is lower compared to other variations. The lowest fuel consumption is found in 70% volume of pertalite and 30% volume of pyrolysis oil which results in fuel consumption of 41.66 km / I.

Abstract

Briquettes are solids that are generally made from agricultural waste materials. Char briquettes are one of the alternative energies for daily needs. This study used char from palm shell and LDPE microwave-assisted co-pyrolysis at 450 Watts. The briquettes were made from the product of co-pyrolysis of palm shell and Low-Density Polyethylene (LDPE) with variations in the composition of 0:100, 50:50, and 100:0 and pressure of 50 kg/cm2, 100 kg/cm2, 150 kg/cm2, and 200 kg/cm2. In this research, thermogravimetry analysis (TGA) was the method used to determine combustion characteristics. This study aimed to determine the combustion characteristics, including the Initiation Temperature of Fixed Carbon (ITFC), Initiation Temperature of Volatile Matter (ITVM), Peak of weight loss rate Temperature (PT), Activation Energy (Ea), and Mass Loss Rate (MLR). The results showed that the increased briquettes pressure increases the ITVM, ITFC, PT, and EA. The higher LDPE composition in the briquettes decreased the ITVM, ITFC, PT, and Ea, but increased the MLR.

Abstract

Biodiesel has attracted attention as an alternative fuel in efforts to reduce emissions and dependence on fossil fuels. Among various potential sources for biodiesel production, jatropha and corn oil have stood out due to their availability and high yield potential. However, each has unique characteristics that affect their performance as fuels. Jatropha oil has relatively high viscosity, while corn oil is generally used as a food ingredient. This study aimed to explore the potential of combining jatropha and corn biodiesel in different proportions and its impact on fuel characteristics and diesel engine spray injection. Both types of oil were processed into biodiesel through esterification and transesterification processes. Subsequently, biodiesel mixtures were created in ratios of 1:4 and 4:1. Each mixture was then varied with diesel to produce B5, B10, B15, B20, B25, B30, B35, and B40. Each sample was tested for its physical properties such as density and viscosity, and injection spray angle. The results of this study indicated that the density and viscosity values of the 1:4 jatropha-corn biodiesel mixture were lower than those of the 4:1 jatropha-corn biodiesel mixture. There was a significant relationship between viscosity and density with the injection angle. The higher the density and viscosity, the narrower the injection angle.
