Abstract

The condensation process of smoke in charcoal-burning systems generates high temperatures that pose a critical thermal risk to PVC piping, which has a melting point of 85 °C. This study presents the design and implementation of a distributed temperature sensing system using dual-channel Type-K thermocouples controlled by an Arduino Uno microcontroller. The system is equipped with fault-tolerant logging and real-time monitoring features, utilizing the MAX6675 thermocouple amplifier module for digital signal acquisition. Two sensors are strategically placed along the smoke conduit to capture temperature differentials between primary and secondary zones. Experimental testing was conducted over six consecutive days with data acquisition sessions at noon and midnight. The highest recorded temperature from the primary sensor reached 83.75 °C, while the secondary sensor recorded significantly lower values, indicating a thermal gradient of 23.8 °C between inlet and outlet. Comparative calibration using an umbrella-type analog thermometer revealed a minimal deviation of 0.41 °C, confirming the system’s accuracy. Two sets of error profiling showed variations in measurement consistency, with average error rates of 13.79% and 5.93% across a 30 °C–80 °C reference range. Voltage stability was maintained throughout all test scenarios, with a constant 5 V input and 4.4 V output. The system successfully demonstrated its ability to perform dual-point thermal detection with resilient performance under fluctuating combustion conditions. This sensor-integrated platform is well-suited for thermal protection and early intervention in biomass-based liquid smoke condensation systems, particularly in small-scale applications using low-melting-point materials such as PVC.

Abstract

A Very rapid population growth has resulted in fossil energy being gradually depleted and environmental pollution getting worse. So far, burning fossil fuels has produced about 40% of global carbon dioxide (CO2) emissions, which are considered a major source of greenhouse gases. The Internal Combustion Engine (ICE) has become the main power source for cars, trucks, locomotives, and ships. In ordinary diesel engines, less than 45% of the fuel energy can be converted into useful work output from the crankshaft, and the remaining energy is largely lost through exhaust gases and jacket water. One way that can be done is to utilize the waste from the internal combustion engine (ICE). This method uses the Organic Rankine Cycle (ORC) system by utilizing the wasted heat generated by the Diesel engine when operating, through the engine coolant coming out of the engine gap (water jacket) to the radiator. In this study, the study focused on the exergy analysis of each component in the ORC system integrated in the diesel engine cooling unit which was simulated using Aspen Plus software. The analytical method used in this study is the exergy method with variations in ambient temperature of 20oC, 21oC, 22oC, 23oC, 24oC, 25oC, 26oC, 27 oC, and 28 oC using the working fluid R141B. The results showed that the greatest exergy destruction was found in the components of the pump, evaporator, and turbine.

Abstract

Penerapan sistem pengereman regeneratif pada kendaraan listrik memerlukan kondisi traksi yang stabil, terutama pada roda belakang yang sering mengalami penurunan gaya normal selama perlambatan. Penelitian ini bertujuan untuk mengevaluasi pengaruh karakteristik suspensi terhadap performa pengereman regeneratif, dengan memfokuskan pada interaksi dinamis antara sistem suspensi belakang dan distribusi beban vertikal. Metode yang digunakan berupa pemodelan matematis kendaraan dengan tujuh derajat kebebasan (7 - degree of freedom), mencakup translasi vertikal, rotasi pitch dan roll, serta respons masing-masing roda melalui sistem pegas dan redaman. Simulasi dilakukan dengan variasi kekakuan pegas antara 20 hingga 60 kN/m dan perlambatan 1,5–3 m/s². Hasil menunjukkan bahwa penurunan gaya normal roda belakang berbanding lurus dengan meningkatnya perlambatan, sehingga menurunkan torsi regeneratif maksimum hingga lebih dari 40 % pada konfigurasi suspensi lunak. Nilai kekakuan optimal ditemukan pada kisaran 40 – 50 kN/m, yang mampu menjaga traksi roda belakang tanpa mengorbankan kenyamanan vertikal kendaraan. Model 7 derajat kebebasan yang dikembangkan terbukti mampu merepresentasikan interaksi antara karakteristik suspensi dan efisiensi pengereman regeneratif secara akurat. Kesimpulan utama dari studi ini adalah bahwa desain suspensi harus menjadi bagian integral dari sistem pengereman regeneratif agar efisiensi energi kendaraan listrik dapat ditingkatkan tanpa mengorbankan stabilitas maupun kenyamanan. Temuan ini dapat menjadi dasar pengembangan lebih lanjut menuju sistem suspensi semi-aktif berbasis kontrol adaptif.

Abstract

The limited availability of electrical training media in motorcycle vocational schools leads to theoretical learning and reduces students’ hands-on experience. This community service project aimed to design, construct, and implement a motorcycle electrical trainer for the Department of Motorcycle Engineering and Business (TBSM) at SMK Negeri 3 Bengkalis. The trainer integrates four main subsystems: lighting, charging, ignition, and electric starter, assembled on a safe and ergonomic educational panel. The method consisted of needs analysis, design, component selection, fabrication, functional testing, module development, and classroom implementation with teacher–student mentoring. Functional tests showed that all subsystems operated according to the design, including protection through fuses and accessible measuring points. Classroom use received positive responses; the trainer was considered relevant to the curriculum and helped students understand circuit flow, perform voltage measurements, and practice basic fault diagnosis. The activity produced a trainer unit, practicum modules, and opportunities for scientific publications and intellectual property.

Abstract

Optimizing valve seat reconditioning requires balancing sealing performance, surface integrity, energy consumption, and component wear within practical workshop constraints. This study presents the design, development, and multi-objective optimisation of a low-cost automatic valve lapping system using a hybrid Response Surface Methodology (RSM) and Non-dominated Sorting Genetic Algorithm II (NSGA-II) framework. A prototype automatic valve lapping rig was developed by integrating a DC-motor-driven spindle with adjustable spring loading and an Arduino-based control and data-acquisition system, enabling controlled variation of spindle speed (300–600 rpm) and axial load (60–140 N). Leakage time, surface roughness (Ra), electrical energy consumption, and valve wear volume were measured using a three-level factorial design. Quadratic response surface models with satisfactory statistical adequacy were established for all responses. The RSM models were employed in NSGA-II to maximise leakage time and minimise surface roughness, energy consumption, and wear, subject to practical operational constraints. The optimisation results reveal clear trade-offs between sealing quality, energy efficiency, and component life, and identify an optimal operating window of approximately 430–470 rpm and 90–110 N, providing a robust compromise solution and a practical operating map for workshop valve seat reconditioning.

Abstract

Waste shredder blades operate under abrasive contact and intermittent impacts from heterogeneous materials, making surface hardness a key property for maintaining cutting performance and reducing premature dulling. This study evaluates the effect of a 850°C heat-treatment route on the hardness of ST37 low-carbon steel used for shredder-blade applications. Plate specimens (100 mm × 100 mm × 10 mm) were prepared and tested under four conditions: untreated (as-received), pack carburizing using coconut-shell charcoal followed by furnace cooling, quenching in used oil, and quenching in saltwater (brine). Hardness was measured using the Rockwell C method (ASTM E18) with a diamond cone indenter (10 kgf minor load and 150 kgf major load). For each condition, ten hardness readings were collected and analyzed using one-way ANOVA (α = 0.05).The untreated specimens yielded an average hardness of 83.85 HRC. The pack-carburized and furnace-cooled condition resulted in a substantial decrease to 69.35 HRC, accompanied by higher variability, indicating a less favorable hardness response under the applied cooling route. In contrast, quenching after heating at 850°C increased hardness to 85.55 HRC for used-oil quenching and 88.35 HRC for brine quenching, with brine showing the highest mean value but also a wider scatter. ANOVA confirmed that the treatment route significantly influenced hardness (p < 0.05). Overall, the results indicate that, under the present parameters, quenching routes are more effective than the pack carburizing + furnace cooling route for improving blade hardness, while process consistency is important to control hardness dispersion, particularly for brine quenching.

Abstract

This study investigates the wear-hardness trade-off of quenched AISI M2 High-Speed Steel (HSS) cutting tools subjected to three austenitizing temperatures (800, 900, and 1000°C) and three quenching media (salt water, Bromus oil, and SAE 20 oil), without subsequent tempering treatment. A factorial dataset consisting of three austenitizing temperatures (800, 900, and 1000°C) and three quenching media (salt water, Bromus oil, and SAE 20 oil) was analyzed under fixed turning parameters (n=300 rpm, f=0.19 mm/rev, a_p=1.5 mm). Tool performance was evaluated using flank wear (VB) and Rockwell hardness (HRC), with five hardness readings per condition to quantify repeatability. The results show a dominant temperature effect: VB decreases monotonically as austenitizing temperature increases, while hardness rises markedly at 1000°C, forming a favorable region with simultaneously low wear and high hardness. The best combined performance was obtained at 1000°C with SAE 20 oil, achieving VB = 0.066 mm and HRC ≈ 82.8. A desirability-style composite index D, derived from normalized VB (smaller-is-better) and HRC (larger-is-better), produced decision and rank maps that consistently identified the 1000°C region as the optimal operating window, with oil quenching preferred when high-temperature austenitizing is feasible. Hardness repeatability metrics further indicated that the 1000°C conditions exhibit the lowest scatter, strengthening their practical robustness. The proposed mapping framework offers a compact, reproducible approach to visualize the wear–hardness trade-off and to rank heat-treatment conditions using existing experimental data.
