Savonius water turbine is one of the simplest design and low cost production that attracts wide attention. A single stage Savonius water turbine with horizontal axis is applied in a pipe with diameter of 3 inch to give variation in the deflector angle. Deflector is used to focusing the flow so the torque is increased by the blade curvature in the turbine. This simulation uses the SolidWork 2013 software. The aim of this simulation is to obtain the best performance in each deflector angle, then the result is compared with a turbine without deflector. The deflector performance is analyzed by the pressure contour, the torque and the angle of attack. The deflector angle is vary in different angle of 20°, 30°, 40° and 50° with the deflector ratio of 50%. By using debit input of 12,2x10-3 m3/s, the results show that angle deflector of 30° is obtained as the best performance where it produce the pressure contour about 279820,99 Pa, torque of 0,6070 Nm and more stable in angle of attack. Keywords: picohydro, SolidWork, Savonius, deflector, torque

Currently, bread is one of the alternative staple foods that is quite in demand by the public. This has resulted in the bread making industry being enthusiastically welcomed by business people because it has bright and open opportunities for large and small scales. However, the Micro, Small and Medium Enterprises (MSMEs) industry is unable to compete. One of them is because of the use of technology in the dough kneading process. This article discusses product planning for a horizontal type of bread dough mixer using the Design for Manufacturing and Assembly (DFMA) method and Quality Function Deployment (QFD) analysis where the design is based on design, materials, analysis, and equipment and manufacturing process planning. In this study, the Action Research method, engineering engineering and the Solidwork simulation design software were used. The design of the machine can be used for a stirring capacity of 10 kg and a rotation speed of 40 rpm. The results of the design consist of several main parts, namely the main frame, container, stirrer, motor, and transmission system

Mertan Village, Sukoharjo has excellent potential in the livestock and agricultural sectors that support goatfarming businesses. This potential has not been utilized by farmers due to lack of knowledge and skills in feedprocessing. Providing good and appropriate feed to goats will increase livestock productivity and farmer income.Skills regarding reproduction by farmers are also still not optimal. Livestock have not been able to achieve efficientreproduction. As a solution to this problem, community service activities are carried out so that farmers can implementimproved feed management through the manufacture of complete feed and silage processing. Improvement in thereproductive aspect can be done by providing assistance to farmers on good and correct reproductive management.The methods used in this community service activity include the transfer of knowledge presented in extensionactivities in the form of: (1) introduction to types of goat feed ingredients, (2) Preparation of complete pellet feed andsilage for goats, (3) Application of feed manufacturing technology, (4) Socialization of goat livestock reproductionmanagement (5) Monitoring and assistance. The results of the activities are that farmers understand and are able toproduce quality feed and carry out reproductive improvements. The community service program that wasimplemented had a positive impact on farmers in Mertan Village, Sukoharjo. The understanding and skills of goatfarmers have increased with this activity. Farmers gain knowledge transfer in the form of types of feed ingredients,feed improvement technology, making quality feed and livestock reproduction efficiency. Farmers' participation inthis activity was very enthusiastic and responded well and received benefits from increasing the productivity of BoerGoat farming

The halal industry is a large and rapidly growing market that encompasses various sectors. This review of literature is motivated by the growing demand for halal products, the importance of trade among Muslim-majority nations, and the need for a deeper understanding of how companies deal with competitive barriers when venturing into new markets. Bibliometric analysis used to identify key publications, authors, and keywords, as well as to track trends and patterns over time. The findings of this study can inform businesses, policymakers, and industry stakeholders about effective approaches to internationalizing halal food businesses and contribute to the sustainable growth of the halal food industry. Moreover, identifying several key research trends and gaps can provide insights for future researchers, especially in unexplored areas within the study of the internationalization of halal food.

The increasing use of composite materials, especially for the two-wheeled vehicle industry, requires an in-depth study of fibre direction. Where the fiber direction can determine the occurrence of initial damage to the composite material. This study aims to produce a composite board from oil palm fruit fibre reinforced with a polyester matrix. In this study, the composite board consists of 3 types, namely sample 1 (discontinuous direction 0°), sample 2 (discontinuous direction 90°), and sample 3 (random fibre direction). The highest bending and impact test results were in specimen 1 with a 0° fibre direction, namely 63.93 MPa and 0.519 Joules/mm2, while the lowest bending and impact test results were in specimen 3 with a random fibre direction, namely 58.63 MPa and 0.382 Joules/mm2. Specimens with horizontal fibre directions have higher strength values. When the fibres are arranged in a 90° direction and a random direction, the mechanical strength is lower, because the load is mostly borne by the material matrix, which is generally weaker than the fibres. Macrophotography at 0° shows that the bonding mechanism of oil palm fruit fibres with the polyester resin matrix is quite good, with visible fibre pullout. This indicates that the bond between the fibre and the matrix weakens as the applied load increases. When the matrix fails, the fibres can still bear the load, so the fracture process does not occur simultaneously with the matrix failure. If the composite fibres become more brittle and the load is distributed to the fibres, which pulls them out, this will result in high toughness and bending strength.
