Abstract

The partner in this program is a collaboration with the Mechanical Students Association (HMM) of all universities studying in the Mechanical Engineering study program which is currently completing its final project in Aceh. The partner's problem is the lack of ability to write scientific articles, and, not knowing how to submit scientific articles via OJS (Oper Journal System), and the solution offered is to provide an introduction to strategies for writing scientific articles and the OJS stages in the journal publishing process, provide training in creating author accounts at OJS, providing training on submitting scientific articles through OJS, outreach on how to write scientific articles, as well as training on writing scientific articles. The results of service activities are that partners can recognize OJS and the OJS stages in the journal publishing process, partners have author accounts and can submit scientific articles to OJS, partners can write scientific articles well and correctly. Monitoring and evaluation are also carried out for the sustainability of further activities to resolve partner problems.

Abstract

Building a safety culture in the home or family environment will tend to be more difficult than building a safety culture in the workplace. This community service program aims to provide health and safety education to housewives in Naga Umbang Village, Lhoknga District, Aceh. Through various outreach activities, such as seminars, workshops and practical demonstrations, it is hoped that housewives can increase understanding and awareness of the importance of good health practices and safety measures in everyday life. It is hoped that the results of this program evaluation can provide constructive input for continuous improvement and increasing the welfare of local communities.

Abstract

This report describes efforts to implement renewable energy technologies as a solution to meet the energy needs of the fishing community in Lam Awe, Aceh Besar. A community engagement approach was used to integrate renewable energy technologies into the daily lives of the fishing community. The study includes the process of identifying community needs, selecting appropriate technologies, and implementing renewable energy solutions. Research methods included participatory surveys, training sessions, and mentoring to ensure active participation and deep understanding from the local community. The results indicate that the implementation of renewable energy can enhance energy access, reduce operational costs, and support environmental sustainability in coastal areas. This report contributes to the context of sustainable technology application for fishing communities, highlighting the importance of collaboration between academics, practitioners, and communities in developing sustainable energy solutions.

Abstract

This study was focused on the characterize the hibridisation of kenaf and sugar palm fibre in reinforcing the polypropylene matrix. Addition of MAPP (Maleic Anhydride Polypropylene) was used as compatibilizing agent with variation of 2%, 3% and 5%. The specimen materials were prepared with 30% amounts of fibres while the ratios between kenaf and sugar palm fibre are 10:20, 15:15 and 20:10. The composites were fabricated using melt mixer technique and followed by compression molding process. The specimens were cut according ASTM Standard D790 for conducting the flexural testing. After testing done, the results shown that flexural strength of composites tend to decreased when the content of MAPP increased. The ultimate flexural strength was attained at 2% MAPP addition of the hybrid composites with 20% kenaf fibres. Among the composites with different ratios, the hybrid composites that contain more kenaf fibres exhibit the higher value in flexural strength than the composites that contain more sugar palm fibres.

Abstract

This study investigates the fatigue behavior of sugar palm fibre (SPF)-reinforced thermoplastic polyurethane (TPU) composites with varying fibre contents (10 wt%, 20 wt%, and 30 wt%). The composites were fabricated using extrusion followed by hot press moulding. Tensile tests were conducted in accordance with ASTM D638 to determine the ultimate tensile strength (UTS), and fatigue tests were performed under stress levels of 80%, 70%, 60%, and 50% of the UTS, following ASTM D7791. The results indicate that an increase in fibre content leads to a reduction in both tensile strength and fatigue life, likely due to poor interfacial bonding and fibre agglomeration. Fatigue life was found to be significantly higher at lower stress levels across all fibre contents. These findings provide valuable information about the potential and limitations of SPF/TPU composites for applications involving cyclic loading, particularly in lightweight and sustainable material applications

Abstract

The development of  biodegradable plastics offers a  sustainable alternative to conventional ones, reducing environmental impact. This research is the fabrication and characterization of biodegradable plastic films derived from large-leafed mangrove (Bruguiera gymnorrhiza) starch, chitosan, and clove essential oil (CEO)  as  an  antioxidant  additive.  Glycerol  was  used  as  a plasticizer, while carboxymethyl cellulose (CMC) and carrageenan were incorporated as thickeners. The effects of glycerol (2.7–9 ml), chitosan (4– 6% m/m), and CEO (0–8% m/m) concentrations on mechanical properties, morphology, and biodegradability were examined. Fourier-transform infrared (FTIR) spectroscopy confirmed the successful incorporation of chitosan and CEO. Scanning electron microscopy (SEM) revealed surface roughness and cavities due to incomplete chitosan dissolution. The optimized formulation (3% starch, 5 ml glycerol, 5% chitosan, and 5% CEO) exhibited superior mechanical properties, with a tensile strength of 710.98 MPa, Young’s modulus of 582.65 MPa, and elongation at break of 121.4%. Soil burial tests demonstrated complete degradation within 14 days. These findings highlight the potential of mangrove starch-based bioplastics for food packaging and eco-friendly applications.
