Abstract

Developments in the field of materials, especially the use of polymers as basic materials, are growing, this is because it meets human needs in improving welfare by processing a basic material into a material that can be used. Synthetic materials such as polymers are widely used in the manufacture of materials combined with other materials. So that it can create new materials either by adding natural fibers or synthetic fibers. Composites can be arranged using natural fibers, such as jute fibers then combined with woven roving. Jute fiber is an organic waste that is widely obtained as a burlap sack hole in traditional markets. Synthetic fibers or artificial fibers have advantages such as strong, corrosion and heat resistant fibers and are easy to mass produce. Making composites can be done several methods, one of which is using the vacuum bagging method with a technique of using pressure to direct the resin to the fibers. The researcher's goal is to determine the characteristics of tensile tests and bending tests using vaccum bagging. There are also tests carried out in the form of tensile tests that refer to the ASTM D638 standard variations of natural and synthetic fiber specimens (hybrid) In the form of yield values of 62.94 Mpa and tensil 85.9. Non-hybrid fibers can be yielded at 28.7 Mpa and tensile at 32.9 Mpa. While the bending test. In hybrid fibers, bending strength is obtained with a value of 1,126.96 MPa. In non-hybrid fibers, bending strength results were obtained with a value of 643.30 Mpa.

Abstract

This study aims to investigate the effect of temperature with constant agitation at 164 rpm on the fabrication of composite materials using the Vacuum Assisted Resin Infusion (VARI) method. In this research, composite materials were made with a polyester resin matrix reinforced with fiberglass. The challenge in the VARI process, which is the difficulty in controlling the viscosity of the solution when infused into the fibers, was addressed by using a stirrer in the feed resin tank. Heating was intended to increase the surface tension of the resin, allowing it to better penetrate the fibers. The variations used were stirring at a speed of 164 rpm and heating temperature variations of 28°C, 35°C, and 50°C. By stirring and heating the resin and catalyst solution, it is expected to achieve a more uniform viscosity, resulting in better composite material compared to methods without heating and without mixing. Based on the test results, the highest average bending strength was found in the specimen stirred with a mixer at 35°C, with a value of 359.91 MPa. The lowest average bending strength was found in the specimen with a temperature variation of 28°C, with a value of 133.7 MPa, and the bending strength at the temperature variation of 50°C was 348.81 MPa. The impact on bending strength is due to the presence of voids, which are gas or air trapped within the specimen structure. This is evidenced by micrographic analysis and density measurements, where the 28°C variation had the lowest density of 2.01 gr/cm3, while the 35°C and 50°C variations had the same density of 2.41 gr/cm3.

Abstract

This study aims to determine the effect of variations in the size of the pineapple leaf fiber frame on the flexural strength and modulus of elasticity of pineapple leaf fiber composites and iron sand. Variations in the size of the pineapple leaf fiber frame used are 5%, 10%, and 15%. The method of making composite specimens uses the vacuum bagging method. Flexural strength testing was carried out using the three point bending method. The results showed that the variation of pineapple leaf fiber frame size had a significant effect on the flexural strength and modulus of elasticity of pineapple leaf fiber and iron sand composites. Test specimens with 15% frame size variation had a maximum flexural strength of 76.9 MPa and a maximum elastic modulus of 639.76 MPa. Test specimens with 10% frame size variation had an average flexural strength of 53.7 MPa and an average elastic modulus of 192.74 MPa. Test specimens with 5% frame size variation had an average flexural strength of 44.3 MPa and an average elastic modulus of 164.04 MPa. The increase in flexural strength and modulus of elasticity of pineapple leaf fiber and iron sand composites with 15% frame size variation is due to several factors, namely: First, the increase in the number of pineapple leaf fibers in the composite. The greater the number of pineapple leaf fibers, the greater the tensile strength and modulus of elasticity of the composite. Second, the increase in composite density. The larger the size of the pineapple leaf fiber frame, the smaller the cavity formed in the composite. Cavities in the composite can reduce the tensile strength and elastic modulus of the composite. Based on the results of this study, it can be concluded that the use of 15% frame size variation as pineapple leaf fiber reinforcement can be used to make a matrix that can increase flexural strength and elastic modulus.

Abstract

Composites are a combination of two or more materials and each has its own properties and characteristics and produces one material with stronger properties than the supporting material. In this study using aluminum, carbon fiber and combined using epoxy resin. This research will produce new material products with variations without surface treatment (TST), HTG, HDG, and 2HDG. The manufacturing process in this study uses the hand lay up method and continues with the vacuum bagging method and is pressed with an iron plate. Shear testing was carried out with the aim of knowing the strength of the specimen against the applied shear force. The results obtained after shear testing of the three TST variations obtained the highest shear stress value in the TST 1 variation of 3.21 MPa and a maximum load of 1141.10 N. Then in the three HTG specimens obtained the highest shear stress value in HTG 1 of 5.54 MPa and 1768.57 N. Then in the three HDG specimens obtained the highest shear stress value in HTG 1 of 5.54 MPa and 1768.57 N. Then in the three HDG specimens, the highest shear value was obtained in HDG 2 of 3.00 MPa and 1005.99 N. Then in the three 2HDG specimens, the highest value was obtained in 2HDG 1 of 2.94 MPa and 1074.59 N. From the test results it is found that the specimen with the HTG variation has a higher shear stress value than the other variations. The type of failure in the kosongan and HTG variation specimens experienced a type of adhesive shear failure and in the HDG and 2HDG variations experienced cohesive shear failure.

Abstract

Rapid technological advances, especially in the field of Unmanned Aerial Vehicles (UAV), have presented new challenges in the development of precision components. UAV, which can operate remotely or autonomously, require highly accurate components to ensure optimal performance and reliability. One important aspect in making UAV components is the casting process, where dimensional errors can affect the final performance of the UAV. This research aims to design and produce J-1B UAV Dies components using the sand casting method using used aluminum material. The research methodology carried out included experiments and observations, starting with 3D design using the SolidWorks application and continuing with making aluminum molds. During the casting process, it is known that the component size experiences significant shrinkage due to cooling of the molten metal, with a shrinkage percentage reaching 5.40% in the body section and 2.11% in the tail section. This shrinkage occurs due to changes in temperature which affect the volume of the metal when it hardens, as well as other factors such as removal of mold patterns and finishing processes which affect the final dimensions of the product. Variability in metal melting temperatures and casting techniques also contributes to product dimensional inaccuracies. This research emphasizes the importance of careful planning and strict quality control to minimize size differences and ensure conformity to the initial design. This research is fully funded by the STTKD campus, which is expected to equip the facilities and infrastructure for STTKD cadets in learning materials and support the development of UAV technology in the future.

Abstract

Traffic congestion in the school environment, especially during school departure and return hours, is a significant problem. This study aims to identify the causes of traffic congestion and evaluate strategies that can be applied in overcoming these problems. The research method used is descriptive with a qualitative approach, using observation, interviews, and documentation as data collection techniques. SWOT analysis was conducted to assess the internal and external factors of the applied strategy. The results showed that congestion is caused by various factors, including student shuttle activities, indiscriminate vehicle parking, limited parking lots, crossing the road, and street vendors selling around the school. The Transportation Agency's efforts include traffic regulation by officers in the field and appeals to schools and parents. However, there are weaknesses in terms of limited human resources and traffic infrastructure. The conclusion of this study is the need to optimize existing strategies, including additional personnel, provision of “kiss and ride” parking facilities, and procurement of more adequate traffic signs. In addition, enforcement of traffic rules and socialization to the community need to be improved in order to maintain smooth traffic flow and improve safety around schools.

Abstract

Perubahan iklim merupakan salah satu tantangan terbesar yang dihadapi dunia saat ini, dengan emisi gas rumah kaca (GRK) sebagai faktor utama yang mempercepat pemanasan global. Kota Palangka Raya, yang terletak di tengah ekosistem lahan gambut yang luas, memiliki potensi besar untuk berkontribusi dalam mitigasi perubahan iklim melalui mekanisme perdagangan karbon. Penelitian ini bertujuan untuk mengidentifikasi potensi, tantangan, dan kebijakan yang mendukung implementasi perdagangan karbon di Kota Palangka Raya dalam rangka mendukung pembangunan ekonomi berkelanjutan dan upaya mitigasi perubahan iklim. Metode penelitian yang digunakan adalah pendekatan kualitatif dengan teknik wawancara mendalam, observasi lapangan, dan analisis dokumen. Hasil penelitian menunjukkan bahwa Palangka Raya memiliki potensi besar dalam menghasilkan kredit karbon dari proyek konservasi lahan gambut dan hutan, yang dapat memberikan manfaat ekonomi bagi masyarakat lokal. Namun, tantangan utama yang dihadapi adalah tingginya laju deforestasi, kurangnya infrastruktur dan kapasitas teknis, serta minimnya partisipasi masyarakat dan sektor swasta dalam program perdagangan karbon. Selain itu, regulasi lokal yang mendukung implementasi perdagangan karbon masih perlu diperkuat. Penelitian ini merekomendasikan peningkatan kesadaran masyarakat, pengembangan kapasitas teknis, dan perumusan kebijakan lokal yang lebih terarah untuk mendukung perdagangan karbon di Palangka Raya. Dengan demikian, perdagangan karbon berpotensi menjadi instrumen yang efektif dalam mengurangi emisi GRK sekaligus mendukung pembangunan ekonomi berkelanjutan di Kota Palangka Raya. Namun, keberhasilan implementasi program ini memerlukan sinergi antara pemerintah, masyarakat, sektor swasta, dan komunitas internasional.
