<![CDATA[Composites made from polylactic acid (PLA) and natural fibers offer a sustainable alternative material that is biodegradable and derived from renewable sources. This review journal examines processing techniques, types of material testing, and the enhancement of the capabilities of natural fiber PLA composites to determine their potential applications as a substitute for conventional materials. From existing research journals discussing PLA and Natural Fiber-based composite materials with applications in various sectors, such as automotive, manufacturing and healthcare, it is known that the commonly used processing techniques are hot pressing and vacuum bagging to produce homogeneous fiber distribution and strong matrix-fiber bonds. Material testing is carried out through tensile tests, elastic modulus, and elongation to evaluate the mechanical properties of the composites. The results also show an increase in mechanical ability of 25-35% compared to pure materials, with fiber surface modification that can improve interfacial adhesion. PLA and natural fiber composites provide a sustainable material solution with competitive mechanical performance. Further research is needed to develop environmentally friendly fiber surface modification methods and scalable manufacturing techniques to expand industrial applications.]]>

<![CDATA[Epoxy resin is a thermosetting polymer widely used in composite materials due to its high mechanical strength, excellent chemical resistance, and strong adhesion. In composite structures, epoxy acts as a matrix that binds and protects the reinforcing fibers while transferring loads between components. The reinforcing fibers may be synthetic (e.g., fiberglass, carbon) known for their high tensile strength, or natural fibers (e.g., kenaf, ramie), which offer advantages in sustainability and low weight. With the growing demand for lightweight, efficient, and environmentally friendly automotive materials, epoxy-based composites show significant potential for use in body panels, interior parts, and structural vehicle components. However, challenges remain, such as poor interfacial bonding between epoxy and natural fibers, thermal degradation, and relatively high production costs. This study aims to systematically review current research trends, applications, and research gaps in the development of epoxy resin composites for automotive components, particularly those reinforced with natural fibers. The method used is a Scoping Review based on the PRISMA-ScR framework, covering 50 scientific articles published between 2015 and 2025. The results indicate that kenaf, ramie, and jute fibers have strong potential as sustainable reinforcements, although improvements in interfacial compatibility and processing technology are still critical. The study implies the importance of advancing bio-based epoxy resins, hybrid manufacturing techniques, and the utilization of local natural fibers as part of a sustainable automotive strategy]]>

<![CDATA[The use of mineral oil based and synthetic coolants in machining processes remains dominant, despite their negative impacts on the environment and occupational health. Vegetable oils have emerged as an environment friendly alternative due to their biodegradable, non toxic properties, and renewable sources. However, thermal and tribological limitations restrict their performance under extreme conditions. To address this, various studies have investigated the addition of nanoparticles to vegetable oils to form nanofluids with improved lubrication and cooling performance. Nanoparticles such as aluminum oxide (Al₂O₃), molybdenum disulfide (MoS₂), and graphene have been shown to enhance thermal conductivity, reduce friction, and form protective tribological layers. This literature review discusses the effect of the combination of vegetable oil and nanoparticles on surface roughness in machining processes. The results show that nanofluids can significantly reduce surface roughness, particularly in Minimum Quantity Lubrication (MQL) systems. The effectiveness of nanofluids is greatly influenced by the type, size, and concentration of nanoparticles, where the optimal concentration varies but remains within a certain range (e.g., 2.5% for Al₂O₃). This study emphasizes that the development of plant-based nanofluids is a strategic approach toward efficient, environment friendly, and sustainable machining.]]>

<![CDATA[Recent research on sustainable heat-treatment processes highlights the strong potential of vegetable oils as environmentally benign quenching media. This review integrates thermo-physical characteristics, cooling behavior, and mechanical performance reported in key studies from 2010–2024. Vegetable oils demonstrate higher quenching severity (H-value 0.17–0.21) than mineral oils (0.11–0.14), supported by stable viscosity ranges (20.78–110.35 cSt at 40°C; 6.9–33.65 cSt at 100°C) and superior thermal conductivity (0.131–0.182 W/m°C) relative to SAE40 (0.145 W/m°C). Their mechanical performance is consistently favorable: palm kernel oil yields hardness up to 40.85 HRC, cottonseed oil ~33.25 HRC, and groundnut oil produces ~173.8 HV with yield strength reaching 805 MPa. Neem seed oil exhibits exceptional hardness (68.7 HRA) and tensile strength (2122 MPa), while marula oil significantly enhances the hardness and tensile strength of medium-carbon steels. Soybean, sunflower, and canola oils applied to AISI 1045 steel deliver hardness levels of 41–50 HRC. Impact toughness also improves, with neem oil reaching 15 J and additive-modified quenchants containing 5% metal salts achieving up to 131 J. Antioxidant-fortified oils (Irganox L109, TBHQ, Propyl Gallate) further improve oxidation resistance without impairing cooling performance. Overall, properly stabilized vegetable oils represent robust, efficient, and environmentally responsible quenching alternatives for the heat treatment of low- and medium-carbon steels.]]>

<![CDATA[Abstract--Increased production of organic waste from the livestock, agriculture, urban, and agro-industrial sectors poses significant environmental challenges if not managed properly. Anaerobic digestion (AD) is an effective technology for processing organic waste while producing renewable energy in the form of biogas. However, the performance of the AD process is greatly influenced by substrate characteristics, such as the carbon to nitrogen (C/N) ratio, lignocellulose content, nitrogen content, and chemical conditions of the substrate. This article aims to conduct a comparative review of various types of animal and plant-based organic waste used in biogas production through the AD process, with an emphasis on methane potential, operational constraints, and process optimization strategies. The method used is a narrative literature review of national and international journal articles discussing the utilization of livestock manure (cattle, chicken, pigs, and goats), food waste, lignocellulosic biomass (rice straw, water hyacinth, and grass), and agro-industrial liquid waste (tofu liquid waste and Palm Oil Mill Effluent/POME). The results of the study show that cow manure has good process stability but relatively moderate methane yield, while chicken and pig manure have higher methane potential but are susceptible to ammonia inhibition. Plant-based and agro-industrial waste generally has high energy potential, but faces obstacles in the form of slow hydrolysis, acidic pH, and nutrient imbalance. Based on the results of the study, anaerobic co-digestion (ACoD) has been proven to be the most effective strategy for optimizing biogas production. This approach is able to balance the C/N ratio, increase buffer capacity, reduce inhibition effects, and improve microbiological stability. The combination of substrates that produces a mixed C/N ratio in the optimal range of 20–30 has been consistently reported to increase methane yield and AD process stability. Thus, substrate selection and formulation through co-digestion are key to developing an efficient and sustainable biogas system.]]>

<![CDATA[he utilization of water energy to generate electrical energy is carried out using a technology called Hydroelectric Power Plant (PLTA). Hydroelectric power plant simulation tools that use software are indeed practical, where students immediately get data and graphs of test results, however, as a result, students do not understand the measuring tools at all. And do not know how to measure data obtained in practicum. The hydroelectric system simulation tool located in the mechanical engineering laboratory of Mercu Buana University experienced trouble with the software so it could not be used. An analysis will be carried out on the hydroelectric simulation tool that will be modified. Therefore, the simulation tool needs to be modified, the modification is done using the VDI 2221 method. Modification of the hydroelectric system simulation tool with the VDI 2221 method so that it can display water discharge, turbine RPM, regulate turbine torque, generator output voltage and amperage. Based on the design results using the VDI 2221 method, 5 variant combinations were produced. Where the design variant 5 best meets the criteria and parameters that suit the needs of the hydroelectric system simulation tool, with an OWV value of 7.76 greater than other variant combinations. This OWV value is an ideal solution that suits the needs. Data processing from the test resulted in a pump brake horsepower of 946 watts, a pump water horsepower of 407.7 watts, a turbine power of 243.99 watts, and a generator output power of 175.2 watts.]]>

<![CDATA[This study investigates the influence of spring pitch on energy storage capacity by analyzing the behavior of a spring-loaded Tamiya car system impacted by a cue ball rolling down an inclined plane. Springs with varying pitches were tested to analyze the relationship between their geometric characteristics and the mechanical energy stored during impact. Using principles of energy conservation, momentum, and restitution, the experiment calculated the spring constant, compression distance, and corresponding energy output. Results indicated that larger pitch distances generally yielded higher spring constants and energy storage, leading to greater displacement of the Tamiya car. Data showed that spring’s ability to absorb and convert kinetic energy is significantly influenced by its stiffness, which is affected by pitch and number of active coils. The study validates theoretical models with experimental outcomes and supports the hypothesis that spring geometry directly impacts energy efficiency. These findings contribute to optimizing spring design for energy storage applications, particularly in mechanical and sustainable energy systems where energy transfer and compact mechanical design are critical. ]]>

<![CDATA[Penetrant testing is a non-destructive testing method used to detect welding defects on the surface of welded materials by applying a penetrant liquid. Its working principle is based on capillarity, namely the ability of a liquid to seep into small openings or defects. This study aims to analyze the effect of dwell time on the results and size of welding defects in Gas Metal Arc Welding (GMAW) using S355J2 carbon steel material. The dwell time variations applied were 1 minute, 3 minutes, 6 minutes, 9 minutes, 12 minutes, and 15 minutes. The test results indicate that variations in dwell time influence the readability of defect indications on the weld surface. The longer the dwell time, the higher the sensitivity of defect detection and the wider the defects revealed. The conclusion of this study demonstrates that selecting the appropriate dwell time in penetrant testing is crucial to obtaining accurate and efficient inspection results in detecting welding defects in S355J2 carbon steel.]]>
