Abstract

The effort to make cow dung has significant added value is the main purpose of this community service activity. The fact is still not much effort to increase the added value of cow dung such as making cow dung into organic fertilizer products with commercial value. Besides, this activity also aims to create a healthy community environment and provide an impact of economic improvement of local communities. Method of implementation of activity begins with observation and mapping area, socialization, implementation, analysis and evaluation, and improvement. The observations were conducted to review the Kalipucang Hamlet area as a whole, interviewing with all components of the community, such as village apparatus and villagers or viewing the field conditions directly as well as doing this mapping to clarify the situation and characteristics of Kalipucang Hamlet related to livestock and land, then socialized to the head of RT, Chairman of the RW, and the local village chief and community. Socialization also serves to explore more deeply about the problems experienced by the community and the solutions needed, so as to provide an output that is in accordance with the wishes and needs of the community. The location of the implementation of this program is in the cattle field of the group Andini Makmur, Kalipucang Hamlet, Bangunjiwo, Bantul, DIY. The series of activities of community service programs that will be carried out include several stages : organic fertilizer material delivery, construction of fertilizer production site, livestock collection, organic fertilizer practice, organic fertilizer monitoring, organic fertilizer cooperative system, launching and evaluation and mentoring. From this activity produced organic fertilizer and successfully established a cooperative that manages the process of making organic fertilizer, packing, until the commercialization. From this activity obtained significant added value in economic aspect as well as from the side of public health because no longer there is pollution from cow dung d neighborhood of residence. Keyword : Cow dung, organic fertilizer, community service, marketing.

Abstract

Blade design and material selection for savonius turbines need to accurate to produce high power input. This research aims to make the most robust blade material by vacuum infusion manufactured. The hybrid laminate composite applied in the manufacture of Savonius turbine blades consists of woven carbon fiber with chopped strand mat glass fiber and woven glass fiber. The variations of fiber composition comprised of five layers, namely 5An (5 layers of woven glass fiber), 5Ac (5 layers of chopped strand mat glass fiber), 2C-3An (2 woven carbon fiber-3 woven glass), and 2C-3Ac (2 woven carbon fiber-3 chopped strand mat glass fiber). The results showed 2C-3An for the best variation of hybrid laminate composite with the tensile strength of 219 MPa, with the modulus of elasticity of 6.8 GPa and the smallest density was 1.21 g/cm3.

Abstract

Due to advancements in the industrial sector, aluminum is progressively gaining popularity as a material of choice in the field of engineering. A pulley is a component that functions as a link or transfers power or engine rotation to the load via the V-belt belt. This study aims to determine the characterization of aluminum material made by the centrifugal casting method from used brake shoes with rotational speed variables of 0 RPM, 100 RPM, and 200 RPM. The characterization of the casting results in this study was analyzed using the Brinell hardness test and the Charpy impact test. The results of the Brinell hardness test showed that aluminum castings for making pulleys with an additional 100 RPM die rotation speed had a Brinell hardness value of 53.22 BHN. The results of the impact test with the Charpy method showed that specimens with a mold rotation speed of 100 RPM had an impact value of 0.0135 kg.m/mm2. The results of this study concluded that variations in rotational speed of 100 RPM in the casting of pulleys made of used aluminum using the centrifugal casting method can produce products that have good toughness.

Abstract

Introduction – VI (Vacuum Infusion) method. The HLC consist of 1 ply carbon woven roving carbon 4 plies glass fiber woven roving (WR-WR), and another variation is 1 ply carbon woven roving and 4 plies glass fiber chopped strand mat (WR-CSM). The different types of glass fiber on the carbon woven roving of HLC is objecting to this research. The manufacture of HLC by VI using 0.8 Bar pressure to flow the polyester resin. The panel HLC cutting according to the ASTM (American Standard Testing and Material) D3039 for tensile strength and ASTM D790 for the flexural test of HLC. The HLC mechanical strength depends on the excellent bonding in the interfacial laminate stress. The direction of WR-WR gives a good effect against tensile load, and the fracture after the test is minor multiple cracks (ductile) and lowest delamination fracture. The WR-WR has the highest tensile stress and modulus by 162.9 MPa and 5.2 GPa, respectively. The flexural test has been resulted in the highest modulus by 8.8 GPa. These mechanical characteristics according to applicated on Savonius Blade Turbine. Purpose – Knowing the mechanical strength of the Carbon/Glass-reinforced hybrid laminate composite, which is suitable for application to the savonius turbine blade Methodology/Approach – We are composing one carbon fiber and four glass fibers in a WR-CSM and WR-WR arrangement. The process of making hybrid laminate composite with the Vacuum Infusion method. Findings – The result of this research is to choose a fiber arrangement that has high mechanical strength and good bonding between fiber layers. Originality/ Value/ Implication – The composite manufacture with vacuum infusion process produces a thin product which light and strong properties.
