Abstract

This study aims to analyze the mechanical strength of composites with bamboo fiber and glass powder reinforcement using an epoxy matrix. The study used a hand lay-up method with three variations of volume fraction composition, namely (1) 15% bamboo fiber, 15% glass powder, 70% resin, (2) 20% bamboo fiber, 10% glass powder, 70% resin, and (3) 25% bamboo fiber, 5% glass powder, 70% resin. The bamboo fiber used was the result of alkali treatment using 15% NaOH solution to remove lignin and cellulose, while the glass powder was obtained from household glass waste with a particle size of 60 mesh. Mechanical property testing included tensile testing (ASTM D638 Type 1), compression testing (ASTM D695-96), and impact testing (ASTM D256), while morphological structure analysis was carried out using Scanning Electron Microscope (SEM) testing. The results showed that the volume fraction composition of 25:5:70 produced the highest tensile strength with an average value of 95.69 N/mm² and the highest impact strength of 29.91 J/mm. Meanwhile, the composition of 15:15:70 obtained the highest compressive strength of 57.13 MPa. SEM analysis of the composite fracture showed the occurrence of full out fiber, debonding, and void phenomena in the matrix, which affected the decrease in the material strength value. This indicates that variations in the composition of bamboo fiber and glass powder can optimize the mechanical properties of composites, while supporting the utilization of natural materials and waste as environmentally friendly innovation materials for automotive applications, especially Yamaha Vixion motorcycle visor products.

Abstract

Nglurah Hamlet is known as the “Kampung Sewu Kembang”. This hamlet is famous as a hamlet producing ornamental plants / flowers that supply various kinds of plants to the Karanganyar area to outside Java. Around Dusun Nglurah there are abundant calliandra plants which are usually used by local residents for raw materials for making fertilizers as fertilizer for ornamental plants. However, the use of calliandra fertilizer is limited to household use, it has not been mass produced and the manufacturing process is still simple. By providing training solutions to the community members of the Nglurah hamlet in the form of life skills, in the form of training in making compost made from calliandra which can be used as a provision for the skills of residents, especially youth groups in the world of work and entrepreneurship, and are ready to compete in the competition in the world of work. Implementation of Community Partnership Program (PKM) activities in Mitra 1, the target solution provided using a training method with a model for delivering material on the theory of the composting process, the practice of making compost and packaging to facilitate sales

Abstract

Kegiatan pengabdian ini bertujuan untuk menerapkan teknologi Mesin CNC Ukir Kayu dengan Sistem Pengaturan Tekanan Otomatis sebagai solusi peningkatan presisi dan efisiensi proses produksi kerajinan kayu di Desa Bantur, Kabupaten Malang. Desa Bantur dikenal sebagai sentra mebel, namun proses produksi kerajinan kayu masih dilakukan secara manual dengan presisi yang rendah. Inovasi mesin CNC ini dikembangkan untuk mengatur gaya tekan pahat terhadap kekerasan kayu secara otomatis menggunakan sensor tekanan dan sistem kontrol berbasis Mach3. Metode pelaksanaan meliputi perancangan mesin, pelatihan pengoperasian bagi anggota Karang Taruna Rajawali 56, dan uji performa alat. Hasil penerapan menunjukkan peningkatan efisiensi waktu produksi hingga 40% dan peningkatan kualitas hasil ukiran sebesar 30%. Penerapan teknologi CNC adaptif ini tidak hanya meningkatkan produktivitas, tetapi juga membuka peluang wirausaha berbasis teknologi di kalangan pemuda desa

Abstract

Structural batteries are a crucial solution in dealing with issues related to vehicle electrification to achieve energy sustainability in the future. However, the development of structural battery technology for electric-powered ships is still very limited. In particular, there are limitations in evaluating the mechanical performance of carbon fiber/polyester-PEG based composite materials for structural battery applications in electrically powered vessels. The main focus of this research is to fabricate carbon fiber/polyester-PEG to further observe the performance of its mechanical properties and structure when interacting with sea water. The value of the addition of polyethylene glycol (PEG) to the fabrication carried out was varied by 0%, 10%, and 25%. The results show that addition of 10% PEG produces a composite with the highest tensile strength, increasing the toughness of the polyester material. However, all samples experienced a decrease in tensile strength after immersion due to decreased bond performance between the fibers and seawater. The addition of 25% PEG resulted in a significant decrease in mechanical properties because high levels of PEG content made the sample easily brittle and destroyed when interacting with seawater. This research can provide initial studies on the development of carbon fiber/polyester-PEG composite materials that can be used as structural battery building materials for future electric boat applications.

Abstract

The purpose of this study is to examine how changing the volume percentage of sisal fiber and mahogany wood powder composites can improve their mechanical qualities. The hand lay-up method was used to create composites with a set resin volume fraction of 50% and varying volume fractions of sisal fiber and mahogany sawdust (30%:20%, 35%:15%, 40%:10%, 45%:5%, and 50%:0%). The tensile test (ASTM D638), bending test (ASTM D790), and impact test (ISO 179-1) were among the tests. According to the results, the best impact toughness (70.34 KJ/mm²) was achieved with a combination of 45% fiber and 5% powder. The composition with the maximum tensile strength (23.36 MPa), strain (0.041%), and elastic modulus (574.20 Pa) was 40% fiber and 10% powder; the composition with the highest bending strength (124.50 N/mm²) was 50% fiber and 0% powder. The best composition from the impact test—45% fiber and 5% powder—is used in this study's rearview mirror cover product.
