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. Keywords: Electric Wheelchair; Ergonomic Assessment; Anthropometry; RULA; Wheelchair Performance

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.

Abstract

Sate is one of the Indonesian specialties whose demand is increasing, so the need for skewers is also getting higher. For this reason, innovation is needed to be able to meet these needs. Because when using skewers in a traditional/manual production method, the quality of the skewers produced is not good and the production capacity is also low. Meanwhile, the existing skewer making machine still has some drawbacks. So in this study, a bamboo cutting machine was designed to increase the production of skewers with innovations to cover the shortcomings of existing machines. In this study, the skewer making machine was designed to have a slicing section, a shavings section (making skewers), and a sharpening section. The skewers produced have a diameter between 2.5 mm to 3 mm and a length of 210 mm with a production capacity of 3000 skewers per hour.

XXX menggunakan boiler tabung api berbahan bakar batubara sebagai uap. Tujuan penelitian ini adalah untuk menganalisis pengaruh nilai kalor batubara dan laju feed water terhadap terhadap efisiensi boiler tabung api 10 ton menggunakan teknik langsung. Data penelitian berasal dari lembar catatan operasi boiler untuk tiga periode pengamatan yaitu 3 Februari, 6 Februari, dan 9 Februari 2025, dengan durasi pengamatan 24 jam. Nilai batubara yang digunakan sekitar 24.001 kJ/kg, 22.644 kJ/kg, dan 23.121 kJ/kg. Menurut hasil penelitian, batubara dengan nilai kalor 24.001 kJ/kg menghasilkan efisiensi rata-rata tertinggi sebesar 78%, sedangkan batubara dengan nilai kalor 23.121 kJ/kg menghasilkan efisiensi rata-rata terendah sebesar 72%. Suhu udara rata-rata berkisar antara 83,0°C, 77,4°C, dan 73,4°C selama berbagai periode pengamatan. Temuan analisis menunjukkan bahwa peningkatan suhu dan suhu batubara feed water dapat meningkatkan efisiensi boiler, sedangkan peningkatan laju feed water berpotensi menurunkan efisiensi boiler. Akibatnya, efisiensi boiler tidak hanya dipengaruhi oleh kualitas bakar tetapi juga oleh kondisi operasi sistem. Oleh karena itu, perlu dilakukan penyesuaian terhadap kedua faktor tersebut untuk mencapai kinerja boiler yang optimal.

Abstract

Penelitian ini menganalisis pengaruh penggunaan tutup bak dan deflektor angin terhadap koefisien drag (Cd) pada truk menggunakan simulasi terowongan angin. Penelitian meliputi empat konfigurasi: truk tanpa modifikasi, truk dengan tutup bak, truk dengan deflektor angin, dan kombinasi keduanya. Variabel bebas meliputi jenis modifikasi dan kecepatan angin (7 m/s, 8,5 m/s, 10 m/s), sedangkan variabel yang terikat adalah nilai koefisien drag (Cd). Hasil percobaan menunjukkan bahwa kombinasi tutup bak dan deflektor angin memberikan penurunan Cd paling signifikan hingga 34% dibandingkan kondisi tanpa modifikasi, diikuti oleh penggunaan individu tutup bak (16%) dan deflektor angin (24%). Penurunan CD ini mengurangi gaya drag secara signifikan, meningkatkan efisiensi aerodinamika, serta mengurangi konsumsi bahan bakar. Dengan demikian, modifikasi ini direkomendasikan sebagai solusi praktis untuk meningkatkan efisiensi kendaraan niaga dan mendukung ekosistem.

Abstract

Penelitian ini mengkaji pemilihan material pada pemotong kertas manual kapasitas besar melalui pendekatan berbasis literatur dan data sekunder, dengan mengacu pada konfigurasi umum produk yang telah tersedia di pasaran. Fokus diarahkan pada analisis karakteristik teknis material dua komponen utama—pisau dan rangka—guna merumuskan rekomendasi desain produk lokal yang efisien, andal, dan tetap ekonomis. Analisis difokuskan pada perbandingan teknis material secara komparatif dan evaluasi multi-kriteria melalui weighted decision matrix. Hasil menunjukkan bahwa material seperti baja perkakas D2 dan SKD11, serta baja paduan rendah solid, memberikan performa unggul pada produk profesional, namun tidak efisien secara biaya untuk skala UMKM. Alternatif material seperti SK5 untuk pisau dan AISI 1020 untuk rangka dinilai mampu memberikan kompromi optimal antara performa teknis dan efisiensi biaya, dengan tetap mempertimbangkan ketersediaan lokal dan kemudahan manufaktur. Kajian ini memberikan kontribusi terhadap perancangan ulang pemotong kertas berbasis prinsip rekayasa material yang adaptif terhadap kebutuhan industri nasional skala kecil dan menengah.
