Abstract

Desa Pegundungan, yang terletak di Kabupaten Banjarnegara, memiliki potensi besar dalam pemanfaatan gas rawa sebagai sumber energi alternatif. Namun, pemanfaatan gas rawa di desa ini belum optimal karena tingginya kandungan gas Hidrogen Sulfida (H₂S) yang bertindak sebagai pengotor. Keberadaan H₂S menyebabkan berbagai masalah, seperti korosi pada peralatan masak dan perubahan warna api menjadi merah, yang berdampak negatif pada efisiensi dan keamanan penggunaan gas rawa sebagai bahan bakar rumah tangga. Untuk mengatasi permasalahan ini, program penerapan alat purifikasi gas rawa telah dilaksanakan. Alat purifikasi ini dirancang untuk memurnikan gas rawa dengan menetralisir kandungan H₂S, sehingga menghasilkan gas yang lebih bersih dan aman untuk digunakan. Program ini melibatkan beberapa tahapan, termasuk observasi awal, perancangan dan pembuatan alat, uji coba, serta pelatihan kepada masyarakat setempat tentang cara penggunaan dan pemeliharaan alat purifikasi. Hasil dari program ini menunjukkan peningkatan kualitas gas rawa yang signifikan, dengan kandungan H₂S yang berhasil dikurangi secara substansial. Sebagai langkah awal, lima alat purifikasi telah dipasang dan manfaatnya sudah dapat dirasakan oleh masyarakat Desa Pegundungan. Program ini diharapkan dapat menjadi solusi berkelanjutan dalam pemanfaatan gas rawa yang lebih optimal dan aman di masa mendatang.

Abstract

This study aims to analyze the effect of variations in the chassis configuration of an electric vehicle prototype on structural performance using the Finite Element Analysis (FEA) method. The chassis was designed using 6061 aluminum with a C-channel profile in three configuration variations: H, X, and Y. Three-dimensional modeling and simulation were performed using Autodesk Inventor 2025 software based on a total static load of approximately 1,668 N, derived from an assumed mass budget of 170 kg for a single-seat prototype, was applied at the driver's feet, seat, and backrest, and at the motor and battery mounts, representing the weight of the driver and vehicle components. The analyzed parameters included the distribution of von Mises stress, displacement, and the safety factor to determine the most optimal chassis configuration. The simulation results showed that all variations met the safety criteria, as they had a safety factor of 15. The H-pattern configuration produced a maximum von Mises stress of 18.13 MPa with a displacement of 0.70 mm; the X-pattern produced a stress of 17.17 MPa with a displacement of 0.57 mm; while the Y-pattern produced the lowest stress of 16.48 MPa with a displacement of 0.59 mm. Based on a comparison of these three parameters, the Y-pattern configuration provides a more even load distribution, resulting in the best structural performance compared to the H and X patterns. The research findings indicate that variations in chassis geometry affect stress and strain characteristics, and can therefore serve as a reference in the development of prototype electric vehicle chassis designs that are lightweight, safe, and have good structural strength.

Abstract

Engine performance refers to the capability of an internal combustion engine to convert input energy, specifically fuel, into useful power. One method to enhance engine performance is to modify components of the intake system that affect airflow. A turbo insulator, which is a modified gasket connecting the carburetor to the intake manifold, is designed to generate turbulent airflow into the combustion chamber, thus improving combustion efficiency. This study aims to design and evaluate a turbo insulator on the intake manifold of a Suzuki Shogun NR-125 CC motorcycle through experimental testing of its impact on engine performance—specifically torque and power. A descriptive analysis method was employed for data analysis. Engine performance testing was conducted using an engine dynamometer, following ISO 1585 standards, within an engine speed range of 3,000 to 9,000 rpm, under standard factory conditions and with various turbo insulator configurations (5 and 7 blades, 45° and 60° blade angles, 4 mm and 8 mm thicknesses). The results indicate that the turbo insulator improves engine performance. The most optimal configuration, V-5 (5 blades, 45° angle, 8 mm thickness), achieved a maximum torque of 11.27 Nm at 3,500 rpm and a maximum power output of 10 HP at 7,750

Abstract

The performance of vortex turbines in ultra-low-head hydropower plants is crucial for harnessing energy in irrigation channels and small rivers. Therefore, an optimal design is needed to maximize the conversion of flow energy into electrical power. This study aims to evaluate and determine the best-performing configuration of ultra-low-head vortex turbines. The method used is Computational Fluid Dynamics (CFD) simulations employing the k-ω Standard turbulence model, with variations in the number of blades (3, 5, and 7) and a fixed blade angle of 15°. The results show that the 7-blade configuration with a 15° angle provides superior performance, generating 3.90 W of power, reducing NPSH by 2%, and increasing force by 6%, with a force value of 52.65 N. The implications of these findings suggest that the 7-blade–15° configuration is a suitable design reference for optimizing ultra-low-head vortex turbines in micro-scale hydroelectric power plants, supporting the utilization of renewable energy in irrigation networks and rural areas.

Abstract

Plasma gasification is a technology that utilizes high plasma energy to convert organic and inorganic materials into syngas. In hot plasma gasification, a plasma torch heats and decomposes waste into synthetic gas (syngas). This study is expected to improve understanding of efficient and effective plasma gasification operating parameters. The experimental method in this study uses variations of DC electric currents of 30 A, 40 A, 50 A, and 60 A, with three replicates conducted for each experimental condition at a constant operating pressure of 5 bar and a gas flow rate of 21 L/min. The highest arc length and temperature were obtained at 60A with argon as the plasma gas (20 mm, 563.67ºC) and with air as the plasma gas (25 mm, 215ºC). Electric current and plasma gas type can affect the efficiency of gasification using a plasma torch; higher electric current increases arc length and temperature. Air can be used as a plasma gas alternative to other plasma gases. This research can serve as a reference for developing gasification technology using a plasma torch.
