Abstract

At this time, the discovery in the field of composites continues to grow. Using foamed polymer composites reinforced with natural fibers continues to be researched and developed to obtain alternative materials to replace metals. Composite materials have unique characteristics and are lighter in weight. Natural fibers from bagasse fiber can function as reinforcement in polymer composites. This study aimed to obtain the effect of variations in bagasse fiber on composite polymer foam materials due to compressive strength loads. This polymer composite material was made by varying bagasse fiber with a mesh fiber size of 300, 400, and 500. Three variations of the constituent materials were measured based on the density ratio of the materials. The constituent materials consist of resin, polyurethane, and fiber, respectively are: label A = (85%, 15%, 0%); label B = (84%, 15%, 1%); Label C = (83%,15%, 2%); and label D = (82%, 15%, 3%). Specimens, for each composition, are three specimens. The technique for making specimens uses the method of pouring into molds concerning ASTM D-638. The testing machine for compressive strength of this polymer composite material using the Tensilon RTF-1350 tool. From the data obtained from the results of the maximum compressive strength test occurs in the fiber size of the specimen labeled D (500 Mesh) with a compressive stress of 5.674 MPa and a strain of 0.186 mm/mm. From these data, it can be concluded that the smaller the size of the bagasse fiber, the better the tensile strength of the polymer foam composite material.

Abstract

Composites are materials that have specific properties based on their constituent materials. The constituent materials consist of binders and reinforcements. Reinforcing materials come from synthetic fibers and natural fibers. Natural fibers can be waste that is wasted in the environment. These wastes include bagasse waste and clam shells. These wastes are made into fibers. Resin is mixed with fiber and blowing agent, then stirred until evenly distributed and poured into the mold, resulting in a composite material. This study aims to obtain the strength of composite materials due to three-point bending loading with the laminate fiber layer method. The manufacture of this test specimen uses bagasse powder and clamshell powder formed with a casting system. This material consists of 4 layers. The first and third layers are clamshell powder, and the second and third layers are bagasse powder. The fiber sizes of the specimens are 300mesh, 400mesh, and 500mesh. The fiber fraction ratio was 10% and 15%. The models were laminated and tested for three-point bending. The best results were found in the 500 mesh fiber size specimen, with a fraction ratio of 85% resin and 15% clam shell powder and bagasse. The maximum stress obtained was 63.46 MPa and strain 0.59 mm, with a bending force of 487.42 N.

Abstract

Reinforced concrete is a crucial element in infrastructure. However, it is unfortunate that the issue of corrosion in reinforced concrete structures has a significant impact and requires detailed consideration. Since the 1980s, research on corrosion-related problems has been initiated, one of which involves the SACP (Sacrificial Anode Cathodic Protection) approach using Zn sacrificial anodes. The purpose of this method is to control the corrosion rate in reinforced concrete. Environmental factors, such as the composition of solutions, play a role in influencing the resulting corrosion rate. Therefore, research is conducted by applying different solutions, namely 4% and 5% NaCl solutions, as well as Freshwater. This aims to compare the effects of these solutions on the measured corrosion rate using Zn anodes. The test results over a 4-week period indicate that the 5% NaCl solution exhibits a very high corrosion rate, as evidenced by the corrosion potential value of -790.3 mV. Conversely, the freshwater solution demonstrates a lower corrosion rate, with a corrosion potential value of -225.6 mV and a corrosion risk of only around 10%. This research provides a deeper understanding of the impact of solutions on the corrosion rate in reinforced concrete and offers a more scientific and contemporary perspective in line with current developments.

Abstract

Renewable energy utilization has become a primary focus in addressing the negative impacts of fossil fuel usage for electricity needs. One proposed solution is using water flow energy through a Pelton turbine. However, traditional materials used in Pelton turbines, especially metals, have disadvantages such as high inertia and susceptibility to corrosion. In this study, we replaced the Pelton turbine's material with fiberglass composite, which offers lower inertia and better corrosion resistance. This study aims to evaluate the performance of the Pelton turbine using fiberglass composite material. Tests were conducted by connecting the turbine to a generator and installing three adjustable nozzles, divided into seven sections based on the number of nozzles opened. Voltage, current, and electric power were measured using a power meter. The results show that with a load consisting of LED light bulbs, the section with one nozzle open (Section 2) achieved the best power output of 1.11 watts, while the section with two nozzles open (Section 6) achieved the best power output of 1.66 watts. Without load, the highest voltage occurred in Section 2 with one nozzle open at 30.9 volts, while the highest power was recorded in Section 4 with two nozzles open at 31.26 volts

Abstract

The manufacturing industry is growing rapidly, especially in terms of industrial workshops. According to BPS data for 2017, in 2016 the development of the manufacturing industry increased by 4.74%. Engineering design or machine design is a series of processes that translate the results of a system into performance, to explain work in detail on the components used. Mechanical pressing is the process of extracting fat or oil through pressure applied to grains with an oil content of around (30%-70%). The aim of the research is to design a machine for squeezing avocado seeds into oil using a screw press, to obtain the length of time for pressing avocado seeds using a screw press and the percentage of biodiesel raw material oil obtained from avocado seeds in 1 kg after going through degumming. This research was carried out using the machine design method, calculating the length of pressing time and the amount of avocado seed seepage. The load pressure on the press is 360 N/m with an electric motor capacity of 0.88 HP and a rotation speed of 17.5 ????????m. Pressing 1 kg of avocado seeds is 58:39 seconds then the raw material for biodiesel oil is 23 grams/1 kg.

Abstract

This research created an innovative single-stage U-type Savonius wind turbine with water hyacinth composite material, intended for low wind speeds. With the steps of wind speed measurement, turbine rotation monitoring, and power measurement, interesting results such as a wind speed of 4.52 m/s producing a power of 5.17 volts were revealed. The significance lies in the potential of the water hyacinth composite turbine in utilizing low wind speeds to generate electricity. The conclusion notes the achievements in the manufacturing process of Savonius turbine blades and suggests that these findings provide an important basis for the development of composite-based wind turbines as an environmentally friendly renewable energy source.
