Abstract

The battery pack is one of the potential parts to be developed on a laboratory scale. The battery pack is a unit of several rechargeable battery cells assembled in series-parallel. Battery packs are generally equipped with a Battery management system (BMS). BMS is an electronic circuit that functions to limit the current and voltage entering the battery in the charging process when the battery is full. This will certainly prevent short circuits and increase battery life. As one of the vocational education institutions, SMK are expected to be able to read and take advantage of existing opportunities related to the increasing number of national vehicles and the acceleration of battery-based electric vehicles according to Presidential Regulation number 5 of 2019. In line with the link and match agenda of vocational universities with SMK, this community service team took the initiative to collaborate with SMK together with PTV as a facilitator and SMK teachers as SMK partners. This training activity begins with preparing an electric vehicle battery pack prototype and testing it in the automotive engine laboratory, engineering drawing and computing studio and DUDI partner workshops. At the end of the training, an evaluation was carried out in the form of a questionnaire on the success of the battery assembly training activities using a linkert scale. As a result, the battery assembly training which activities are measuring and monitoring battery pack, increase the knowledge of teachers about how to assemble 18650 lithium ion batteries according to the requirements of the motor that is used.

Abstract

Polypropylene is widely used in the automotive industry because it is lightweight, inexpensive, and easy to process, but it has limitations, including relatively low mechanical properties and a tendency to shrink. Cellulose nanofiber is used as an environmentally friendly reinforcement with high strength, but differences in properties between hydrophobic polypropylene and hydrophilic CNF result in poor compatibility. To overcome this, a polypropylene-graft-maleic anhydride (PP-g-MA) coupling agent is added to enhance interfacial bonding. This study aims to evaluate the effects of CNF and PP-g-MA content on the mechanical properties, thermal stability, and water resistance of polypropylene materials produced by extrusion and injection molding. The outcomes show that substituting 1 wt% CNF provides significant reinforcement, elevating the tensile strength to 22.90 MPa and the flexural strength to 29.70 MPa. At higher CNF contents, agglomeration occurs, leading to decreased mechanical properties and increased water absorption up to 0.35%. The substitution of PP-g-MA increased the compatibility of the PP/CNF composite, as indicated by the appearance of an ester peak in the FTIR, an increase in crystallinity in the DSC/XRD, and a shift in the onset of degradation by 340°C to 350°C in the PP/1CNF/5PP-g-MA composite. This formulation also produced a tensile strength of 25.60 MPa, a flexural strength of 33.00 MPa, and low water absorption. Although substituting CNF reduced impact strength, using PP-g-MA restored impact strength to near that of pure polypropylene. Overall, the PP/1CNF/5PP-g-MA composite was determined to be the optimal composition due to its balanced mechanical properties, thermal stability, and water resistance.

Abstract

This study investigates the fuel flow rate and engine rotational speed characteristics of a plug-in hybrid electric motorcycle using a Hybrid Control System Module Modification Combination Management (HCS-MCM) framework. The proposed system is designed for conversion-based applications at the workshop level, addressing the gap between advanced hybrid control strategies and practical implementation. A parallel hybrid configuration was adopted, integrating an internal combustion engine (ICE) and a 3 kW electric motor with a gear-dependent control strategy. Experimental testing was conducted under first and second gear conditions by analyzing the relationship between vehicle speed, engine speed (RPM), and the time required to consume 5 ml of fuel. The results show that the hybrid system consistently produces longer fuel consumption times compared to the conventional system, indicating improved fuel efficiency. The most significant improvement occurs in first gear, where the electric motor provides dominant torque assistance at low speeds, reducing the load on the ICE. In second gear, the hybrid system still demonstrates better efficiency; however, the performance gap decreases as the ICE becomes more dominant at higher speeds. These findings confirm that the proposed HCS-MCM framework effectively enhances fuel efficiency, acceleration performance, and energy utilization. The study contributes to the development of practical hybrid control systems for motorcycle conversion, particularly for small-scale workshop applications in developing countries.

Abstract

This study presents the optimization of burner design and experimental evaluation using liquid fuel derived from polypropylene (PP) waste pyrolysis to achieve high thermal efficiency. The increasing accumulation of plastic waste and rising energy demand have driven the development of alternative fuels and more efficient combustion systems. In this work, polypropylene waste was converted into liquid fuel through a pyrolysis process and subsequently utilized as the primary fuel in a modified burner system. The optimization focused on key design parameters, including nozzle diameter, air–fuel mixing configuration, and combustion chamber geometry to enhance atomization quality, flame stability, and heat transfer performance.Experimental tests were conducted under various operating conditions to evaluate combustion characteristics, fuel consumption rate, flame temperature, and thermal efficiency. The results show that the optimized burner configuration produced a stable blue–orange flame with improved atomization and more complete combustion compared to the initial design. The maximum thermal efficiency achieved was 105.54%, indicating a significant improvement due to better air–fuel mixing and reduced heat losses during the combustion process. Furthermore, the pyrolysis oil demonstrated strong potential as an alternative liquid fuel for small-scale thermal applications.This study provides a practical contribution to waste-to-energy technology by integrating burner design optimization with plastic waste-derived fuel utilization, offering an effective approach to enhance thermal system performance while supporting sustainable and scalable small-scale energy solutions.
