Abstract

A generator is a device or engine that generates electrical energy from the presence of mechanical energy obtained from a prime mover in the form of a diesel engine as the prime mover which then drives an AC generator or alternator, causing an electrical voltage. The aim of this research is that the generator can supply electricity needs at the Sumur Welut site by changing or modifying diameter of the wire on the alternator. This analysis includes the Stator and Rotor on the Alternator generator so that it can produce the electricity needed. From the test results, the load generated after being modified can supply power at the site but the fuel consumption is more wasteful, namely 0.9 liters / minute and also the generator temperature increases to 88.2 C. So that the radiator planning is done by changing the surface area of ​​the radiator from 2915 cm2 to 8077 cm2. Or change the radiator fan, which originally changed the wind speed of 4.7 m / s to 13 m / s. Keywords: Generator, Alternator, Load Testing, Radiator, Cost.

Abstract

Indonesia is a tropical country, which gets a lot of sunshine every year. Harvesting energy from solar heat is an alternative solution to obtain renewable and environmentally friendly electrical energy. The purpose of this research is to design and test the temperature and flow of the working fluid of a solar collector for energy harvesting. The method used is true experiment research by making a solar collector prototype. Measurement of the temperature and pressure of the working fluid is carried out by varying the power of the heating lamp as a substitute for sunlight in the test. The experimental results show that the greater the heat energy received by the solar collector, the higher the temperature of the working fluid and the resulting pressure during the same test. The highest temperature recorded for the liquid coming out of the solar collector reaches 63.6 oC with a maximum pressure difference of 19.6 Pascals. The results of this test will be followed by testing the flow rate of the working fluid to determine the power potential of the working fluid for harvesting energy. Highlights: Efficiency Enhancement: Optimizing solar collector design for increased heat energy absorption and efficient energy conversion. Temperature-Pressure Correlation: Investigating the relationship between heat energy, working fluid temperature, and pressure for better energy yield. Flow Rate Analysis: Assessing working fluid flow to gauge energy potential and inform effective energy harvesting strategies. Keywords: solar collector, temperature, fluid pressure, energy harvesting

Abstract

The increasing demand for renewable energy has encouraged research into the development of bioethanol from abundant local raw materials, one of which is corn kernels which are rich in starch. This study was conducted to determine the effect of variations in distillation temperature on the volume and purity of bioethanol produced from fermented corn kernels. The research process begins with material preparation, namely sowing corn kernels until they germinate, grinding, then fermenting with yeast (Saccharomyces cerevisiae) for 7 days. The fermentation results were then distilled for 30 minutes using a simple distillation apparatus with three temperature variations, namely 70°C, 80°C, and 90°C. The volume of bioethanol was measured using a measuring cup, while the ethanol content was tested using an alcohol meter. The results showed that at a temperature of 70°C a volume of 130 ml of bioethanol was obtained with a purity of 67%, at a temperature of 80°C a volume of 168 ml was obtained with the highest purity of 83%, while at a temperature of 90°C the volume increased to 191 ml but the purity decreased to 73%. The data demonstrates a trade-off between ethanol volume and purity, where higher heating temperatures increase volume, but purity does not always increase. This study concludes that the optimal distillation temperature is 80°C, as lower energy can produce bioethanol with a combination of a relatively large volume and the highest purity.

Abstract

General Background: Electric wheelchairs are widely used to support mobility and daily activities for individuals with physical disabilities. Specific Background: User comfort and operational capability of electric wheelchairs are strongly associated with ergonomic suitability, anthropometric compatibility, and technical performance under different operating conditions. Knowledge Gap: Previous studies have not sufficiently evaluated the relationship between user anthropometry, upper limb posture, and the mechanical performance of non folding electric wheelchairs for users with specific physical limitations. Aims: This study aimed to evaluate the ergonomic suitability and performance characteristics of a non folding electric wheelchair using anthropometric analysis, Rapid Upper Limb Assessment (RULA), and propulsion and steering performance testing. Results: The findings showed several mismatches between user body dimensions and wheelchair dimensions, particularly in footrest height, footrest length, and armrest height. RULA analysis produced a score of 4, indicating that posture modifications are required. Performance testing demonstrated that the wheelchair could carry loads up to 120 kg and travel approximately 15.36 km on a full battery charge, but limitations were identified in climbing ability, maximum speed, steering control, and obstacle clearance. Novelty: This study integrates ergonomic evaluation and technical performance testing on a non folding electric wheelchair designed for users with asymmetric physical conditions. Implications: The results provide practical recommendations for improving wheelchair ergonomics, steering stability, energy efficiency, and mechanical configuration to support safer and more comfortable mobility for users with disabilities.Highlights: Anthropometric comparison identified dimensional mismatches in armrest and footrest configuration. Postural evaluation indicated corrective adjustment requirements for upper body positioning. Mechanical testing revealed limitations in slope navigation, steering response, and maximum travel speed.

Abstract

Sprayer penghasil busa, atau foam sprayer, adalah alat yang digunakan untuk menghasilkan busa tebal dan lembut, sering kali terhubung dengan pressure washer. Ada juga handheld foam sprayer yang portabel dan dipompa secara manual, cocok untuk penggunaan kecil. Keunggulan sprayer ini terletak pada kemampuannya mengangkat kotoran tanpa menggores cat kendaraan, berkat busa yang bertindak sebagai pelumas. Penelitian ini memodifikasi handheld foam sprayer menjadi otomatis menggunakan kompresor dengan mengganti pompa sprayer dengan sliplock yang disambungkan ke pressure gauge. Pengujian tekanan pada sprayer yang dimodifikasi bertujuan untuk mengukur performa dan efisiensi penyemprotan. Tekanan yang tepat sangat penting, karena tekanan rendah menghasilkan semburan tidak merata, sedangkan tekanan tinggi berisiko merusak sprayer. Pengujian dilakukan tiga kali dengan takaran 1 liter air dan 50 ml sabun pada tekanan 10, 20, dan 30 Psi. Hasil menunjukkan bahwa tekanan yang lebih tinggi menghasilkan lebih banyak busa: pada 10 Psi, total campuran 260 ml (50 ml air dan 210 ml busa), pada 20 Psi menjadi 320 ml, dan pada 30 Psi mencapai 430 ml. Uji penyemprotan sabun pada spakbor menunjukkan efektivitas dalam mengangkat kotoran. Hasilnya, pada 10 Psi, spakbor masih kotor, sedangkan pada 20 Psi terlihat lebih bersih, dan pada 30 Psi, hasilnya sangat memuaskan dengan spakbor yang bersih. Penelitian ini menunjukkan bahwa variasi tekanan berpengaruh signifikan terhadap efektivitas pembersihan. Peningkatan tekanan meningkatkan jumlah busa dan kemampuan sprayer dalam membersihkan. Dengan demikian, pemahaman mengenai tekanan penyemprotan sangat penting untuk mencapai hasil pembersihan yang optimal dan memperpanjang umur alat.
