Abstract

Penyulingan minyak nilam dilakukan dengan energi panas yang diperoleh dari hasil pembakaran kayu bakar didalam dapur atau minyak tanah dengan menggunakan burner. Diperlukan suatu rekayasa untuk dapat meningkatkan efisiensi penggunaan bahan bakar yang ada, sehingga dapat menekan biaya produksi bagi industri kecil penyulingan minyak nilam. Salah satu upaya peningkatan efisiensi penggunaan bahan bakar adalah dengan memanfaatkan sisa panas pembakaran yang keluar dari dapur menuju pipa cerobong asap. Temperatur udara panas yang keluar dari cerobong masih cukup tinggi, sehingga perlu dimanfaatkan. Sistem penyulingan yang digunakan adalah sistem ganda yang terdiri dari ketel induk dan ketel kecil Berdasarkan tekanan tertinggi yang dihasilkan oleh ketel yaitu 14 kg/cm2 kondisi uap yang dihasilkan adalah uap jenuh karena tekanan tersebut lebih besar dari tekanan uap untuk air mendidih yaitu 11 kg/cm2. Kebutuhan bahan bakar yang digunakan untuk menghasilkan uap dari ketel adalah rata-rata 6 s/d 7 kg dengan kapasitas ketel induk 5 kg dan ketel kecil 2 kg.

Abstract

A vortex turbine is a turbine that operates by utilizing a vortex flow as a drive for turbine blades which then the turbine shaft is connected to a generator to convert shaft mechanical energy into the form of electrical energy. In this study a test will be carried out on a vortex turbine with a head of 1 m, a flow rate of 0.12 m3/s. In the testing process, 3 types of blades will be used, namely straight blades, curved blades and finned curved blades. After testing, it can be concluded that the highest power is found in the curved blade of 959.08 Watt and then the finned curved blade is 714.38 Watt, while the lowest power is found in the straight blade type of 582.48 Watt. The resulting rotation can be seen in the graph below. The highest rotation is found in the finned curved blade of 540.00 rpm and the next is the curved blade of 517.67 rpm, while the lowest rotation is found in the straight blade type of 510.67 rpm. For the efficiency of each metal blade, it can be seen that curved blades are still the highest followed by curved blades with finned blades, the lowest being straight blades with salty blade efficiencies of 98%, 73% and 59%

Abstract

Continuously Variable Transmission (CVT) transmission system on automatic motorcycles has an important role in efficiently distributing engine power to the wheels. One of the main components in the CVT system is the secondary spring, which plays a role in regulating the back pressure of the secondary pulley to maintain belt tension in the power transfer process, the level of secondary spring stiffness can affect the characteristics of power transfer. This study aims to analyze the effect of the stiffness of the Dytona brand secondary spring with three variations of stiffness (1000 RPM, 1500 RPM, 2000 RPM) on the performance of the Honda Scoopy motorcycle. The method used is an experiment with a quantitative approach, where each variation of the secondary spring is tested using a BRT 50 LA dyno test machine to obtain data such as power, torque, acceleration and top speed. The test results show that the secondary spring with lower stiffness provides a faster initial response and is able to maintain the transmission ratio longer at high speeds. Meanwhile, the secondary spring with higher stiffness provides a greater power boost, but reduces top speed because the transmission ratio decreases faster. It can be concluded that the selection of secondary spring stiffness must be adjusted to the desired performance characteristics, whether to achieve maximum power or optimize acceleration efficiency and high speed. This finding can be used as a reference in modifying the CVT system to improve motorcycle performance, especially the Honda Scoopy

Abstract

The blade on the cane cutter machine is the part most susceptible to damage because it operates under dynamic conditions with high impact loads, continuous friction, and rapid rotation. Blade damage on the cane cutter at PG Krebet Baru I is a recurring problem, with replacement frequency reaching six times per milling season. The topic of this research is to analyze the strength of the cane cutter blade at PG Krebet Baru I using ANSYS Workbench 2025 R1 software. The blade strength analysis includes stress distribution, deformation, and safety factor for each load variable using ANSYS Workbench 2025 R1. The limitations of this study include: simulations conducted only on the cane cutter blade under static load conditions, and data used as the basis for the simulation include blade dimensions, material type, and rotation speed of the cane cutter machine at PG Krebet Baru I. The results of the calculations obtained the loads applied for the simulation, namely a minimum load of 5,707 N, an average load of 8,561 N, and a maximum load of 11,415 N. The simulation results of the cane cutter blade showed that at a minimum load of 5,707 N, the Maximum Total Deformation was 0.048 mm, the Maximum (von-Mises) Stress was 22.3 MPa, the Maximum Shear Stress was 12.9 MPa, and the Safety Factor was 11.2. At the average load of 8,561 N, the Maximum Total Deformation was 0.073 mm, the Maximum (von-Mises) Stress was 33.4 MPa, the Maximum Shear Stress was 19.3 MPa, and the Safety Factor was 7.4. And at the maximum load of 11,415 N, the Maximum Total Deformation was 0.097 mm, the Maximum (von-Mises) Stress was 44.6 MPa, the Maximum Shear Stress was 25.7 MPa, and the Safety Factor was 5.6

Abstract

Kinerja sistem pembakaran pada multi-fuel boiler sangat dipengaruhi oleh karakteristik pasir silika sebagai bed material serta kecenderungan terjadinya sinterisasi dan aglomerasi akibat kontaminasi abu biomassa. Penelitian ini menganalisis parameter hidrodinamika bed meliputi Archimedes Number (Ar), Reynolds minimum fluidization (Remf), dan kecepatan minimum fluidisasi (Umf) bersamaan dengan indeks-indeks kimia abu, seperti Ash Index (AI), Bed Index (BI), Agglomeration Alkali Index (AAI), Alkali/Silica ratio, Sintering Agglomeration Risk (SAR dan SART), serta parameter termal seperti PFR, TRF, CRI, dan FI. Data hasil pengamatan menunjukkan nilai Ar berada pada rentang 1,06×10⁶ – 1,27×10⁶, yang mengindikasikan karakteristik partikel pasir dominan berada pada regime fluidisasi stabil. Nilai Remf (177–197) dan Umf (1,04–1,08 m/s) memperkuat bahwa kondisi operasional boiler berada di kisaran fluidisasi yang aman. Indeks kimia menunjukkan AI (0,11–0,13) dan BI (0,08–0,09) tergolong rendah, menandakan risiko fouling dan slagging yang minimal. Rasio Alkali/Silika (0,15–0,19) masih berada dalam batas aman sehingga tidak memicu reaksi pembentukan silikat bertitik leleh rendah. Nilai AAI (0,116–0,151) serta SAR (0,86–1,12) menunjukkan bahwa potensi aglomerasi berada pada tingkat moderate, dipengaruhi oleh variasi kandungan alkali dalam fuel mix (bark, fiber, dan mixed biomass). Parameter termal TRF (0,02–0,29) dan CRI (0,31–0,42) memperlihatkan kecenderungan moderat terhadap pembentukan kerak pada temperatur tinggi, sedangkan FI (0,66–0,73) berada pada kategori stabil. Secara keseluruhan, hasil analisis menunjukkan bahwa kondisi operasi fluidized bed boiler pada industri pulp & paper dalam penelitian ini stabil dan berada dalam rentang aman, dengan risiko sinterisasi dan aglomerasi tergolong moderate–rendah. Pengendalian ukuran pasir, pemantauan kontaminasi alkali, dan optimasi rasio fuel mix direkomendasikan untuk menjaga keandalan operasi jangka panjang.
