Abstract

Congestion at toll roads has become a pervasive issue in contemporary times, predominantly manifesting at toll booths during the payment process. A noteworthy contributor to this congestion has been identified as the sluggish operational speed of boom gates. In response to this challenge, a modification strategy was implemented to enhance the operational efficiency of existing boom gates. The primary modification involved substituting the conventional electric motor with a more advanced Brushless DC (BLDC) motor boasting a power rating of 660 watts. Additionally, an innovative augmentation integrated a motorcycle disk brake system into the boom gate mechanism. Replacing the original electric motor's internal brake system with the disk brake system aimed to optimize the overall performance of the boom gate. The integration of the motorcycle disk brake system was further complemented by incorporating the push braking system (knoken braking system), serving as the actuator instead of the traditional motorcycle lever handle. This strategic substitution was instrumental in activating the disk brake function at the boom gate. During peak rush hours, the modified boom gate underwent rigorous testing at both the Ciawi and Kelapa Gading toll gates. Results from the trial activities unveiled a remarkable improvement in the boom gate's operational speed. Specifically, the opening speed demonstrated an impressive surge of 51 percent, catapulting from 548 ms to 265 ms. Similarly, the closing speed exhibited a commendable enhancement of 44 percent, elevating from 602 ms to 332 ms. Furthermore, the boom gate cycle per hour experienced a notable escalation, increasing by 25 percent from 356 to 449 cars per hour. These findings underscore the efficacy of the implemented modifications in ameliorating congestion issues at toll booths.

Abstract

Drying cassava pulp is an important stage in the cassava processing process so that the final product has good quality and high shelf life. This research aims to design and calculate the heating system in a cassava pulp drying machine based on a rotary dryer with a capacity of 5 kg/hour. The methods used include preliminary studies and field observations, literature review, and technical calculations including air flow velocity, moisture content, heat required, drying efficiency, and fuel requirements. The calculation results show that the total heat energy required to reduce the water content of cassava pulp from 20% to 5% is 2176.73 kJ, while the heat provided by the heating air is 4493.88 kJ with a thermal efficiency of 48.44%. The fuel used is LPG with a requirement of approximately 50 grams per drying cycle. The system shows potential as an effective alternative to traditional drying methods, especially for household or micro-enterprise scale. Further optimisation is required to improve the thermal efficiency and heat distribution.

Abstract

Floods are the most frequent natural disasters that hit Indonesia and have a major impact on people's lives, especially in coastal areas such as Brebes which often face flash floods, so that conventional transportation systems are often completely paralyzed and hinder the evacuation process and distribution of aid. This research aims to develop amphibious motorcycles as an affordable alternative transportation solution in accordance with local conditions by utilizing local materials such as Styrofoam to overcome the limitations of access to similar technology in Indonesia. The research method used an experimental approach by designing and testing an amphibious motorcycle buoy made of used Styrofoam fruit boxes coated with plywood and fiber with dimensions of 179 cm × 37 cm × 38 cm per unit, mounted on Honda Beat motorcycles. The test was carried out through four loading variations ranging from no-load conditions to a maximum load of 223 kg, by measuring the depth of the dipped float to evaluate buoyancy based on the Archimedes principle. The results showed that the buoy was able to withstand a maximum load of 223 kg in stable conditions with a dip depth of 17 cm, resulting in an actual buoyancy force of 119 N although theoretical calculations showed a maximum capacity of 432 kg (4,233.6 N). The buoy system with a total weight of 24 kg (2 units) has a safety margin of 55.3% and is capable of operating with passengers up to 80 kg with maintained stability. This study validates that the design of the amphibious motorcycle has a strong theoretical basis and has been experimentally proven as an effective emergency transportation solution based on local materials for flood disaster mitigation in Indonesia.

Abstract

This article reviews the fabrication methods of metal matrix composites (MMCs) in liquid state. Metal matrix composites, especially aluminium metal matrix composites (AMMCs), are widely used in automotive, aviation, and medical industries due to their superior properties such as low density, good wear resistance, and specific strength. Liquid-based manufacturing processes include infiltration, stir casting, centrifugal casting, squeeze casting, vacuum die-casting, compocasting, and rheocasting. Each method offers specific advantages in reinforcement distribution, cost efficiency, and complex shape manufacturability. Infiltration is effective in achieving good interfacial bonding; stir casting is popular because it is simple and economical for mass production; centrifugal casting excels in forming high-density and wear-resistant composites; squeeze casting and vacuum die casting increase the strength and density of composites; while compocasting and rheocasting offer more homogeneous microstructure and grain refinement. This review shows that the selection of method should be based on the specific application requirements and material characteristics to achieve optimum mechanical properties. With improvements in technology and control of process parameters, liquid casting methods offer significant potential for the manufacture of high-performance structural and functional components.

Abstract

The modern industrial era is characterized by the high complexity of systems and the demand for operational efficiency, making maintenance systems play a crucial role in ensuring reliability, safety, and sustainability of production processes. Reliability-Centered Maintenance (RCM) has emerged as a strategic approach to replace conventional Preventive Maintenance (PM) methods, which are often static and inefficient. This study compares the effectiveness of RCM and PM in terms of maintenance cost and risk through a literature review across various industrial sectors, including power generation, automotive, maritime, food and beverage, and energy distribution systems. The results show that RCM implementation can reduce unplanned downtime by up to 55.77%, increase system reliability by 28%, lower maintenance costs from 20% to 70%, and raise system availability from 57% to over 90% in some cases. RCM has also proven to be more adaptive to actual equipment conditions, supports risk-based decision-making, and is more effective in scheduling maintenance for critical assets. Although its implementation requires more data resources and technical expertise, RCM demonstrates superior long-term performance. This study recommends the integration of a hybrid strategy that combines the strengths of RCM, PM, and predictive approaches powered by digital technologies to comprehensively enhance the efficiency and reliability of maintenance systems.

Abstract

Post-Weld Heat Treatment (PWHT) is a widely employed thermal method used to relieve residual stresses and enhance the mechanical properties of welded joints. This study investigates the effect of PWHT on the mechanical and microstructural properties of SS400 steel welded using the Gas Metal Arc Welding (GMAW) process. The research focuses on evaluating how variations in PWHT temperature influence tensile strength. impact toughness. hardness. and microstructural characteristics. Specimens were subjected to PWHT for 1 hour with a 15-minute holding time. followed by natural cooling at room temperature. The results indicate that PWHT significantly improves impact toughness and refines grain structure. especially in the Heat Affected Zone (HAZ). while leading to a reduction in tensile strength compared to untreated specimens. Higher PWHT temperatures promoted the formation of finer ferrite and bainitic phases. contributing to enhanced ductility and toughness but reduced hardness due to grain coarsening. Microstructural analysis confirmed a shift in phase composition. where an increased ferrite content resulted in lower hardness. while a dominant pearlite phase corresponded with higher hardness values. Overall. this study highlights the importance of optimizing PWHT parameters to achieve a desirable balance between strength. hardness. and toughness in SS400 welded joints. particularly for structural applications such as shipbuilding.

Abstract

Surface quality of machined parts is an important indicator in determining the final performance of engineering components. One of the main factors influencing this parameter is the type of coolant used during the cutting process. This study is a literature review aimed at systematically comparing the effects of synthetic, mineral, and vegetable-based coolants on surface roughness in various machining processes such as turning, milling, and drilling. The literature review method involved searching reputable scientific articles indexed in Scopus, with a focus on quantitative surface roughness data (Ra). The analysis results showed that plant-based coolants provided the best performance, with a reduction in Ra values of up to 55% compared to conventional mineral coolants. Meanwhile, synthetic coolants demonstrated high cooling capabilities but their lubricating properties remained below those of plant-based coolants. Mineral fluids were found to have the lowest performance in terms of surface quality and environmental impact. This study confirms that the use of plant-based fluids, particularly in Minimum Quantity Lubrication (MQL) systems, is a promising solution for achieving efficient, sustainable, and environmentally friendly machining processes.

Abstract

Noise control is a growing concern in built environments, vehicles, and industrial machines. Porous multi-layer composite materials are currently the most used for this purpose. Some of them are felt-based materials widely utilized in acoustic applications due to their excellent sound absorption properties, flexibility, lightweight nature, and low manufacturing cost. Some synthetics & hybrid fiber materials are widely used for acoustic purposes. To optimize the acoustic performance, one of the materials, such as resinated felt, is commonly combined with nano-porous materials like spunbond, a PET-based non-woven material, as a skin layer due to their adjustable fiber structure and cost-effectiveness. Bonding compression techniques—including hot pressing, thermal bonding with low-melting fibers, and skin lamination spunbond are crucial in fabricating multi-layer acoustic composites from porous materials. This review synthesizes findings from studies detailing process parameters, material choices, and how compression affects porosity, fiber entanglement, and inter-layer bonding to optimize sound absorption. Special attention is given to the effects of processing parameters on porosity, air permeability, and fiber orientation—factors that critically influence acoustic behavior. Challenges such as frequency-dependent performance loss and scalability limits are discussed. Future research should target the development of the cycle optimization process and real durability evaluation.

Abstract

Motor vehicle exhaust emissions containing carbon monoxide (CO) and hydrocarbons (HC) are a strategic issue for Indonesia, which has not yet set an age limit for motor vehicles. As a control measure, the Indonesian government itself has issued regulations on exhaust gas emission quality standards for motorized vehicles that are used by the public through Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 8 of 2023. Catalytic converter technology is the most effective system for reducing CO and HC emissions. Currently, it is from the Platinum Gold Metal (PGM) group, namely Platinum, Palladium, Rhodium which is still very expensive. This article uses a literature review research method with reference sources originating from previous research journals by comparing. This paper will discuss gas emissions, the development of converter catalytic materials and also the effectiveness of converter catalytic materials from the non-PGM metal group, namely Copper (Cu) and Brass/ Brass (CuZn) which has been proven to be able to reduce exhaust gas emissions so that it can be an alternative as a converter catitic at a more affordable price for the wider community
