Analisa Variasi Saringan Mesin Penggiling Daging Ayam Kapasitas 1 Kg Terhadap Waktu
Get PDFBakso is a type of chicken meat ball that is commonly found in Indonesian cuisine. Currently, chicken meatballs are one of the processed chicken meat products that have a particular taste. The biggest energy contribution comes from protein, which reaches 60 percent, followed by fat as much as 38% and carbohydrates as much as 2%. The high public demand for processed products such as chicken meatballs has resulted in most shops, from stalls, school canteens, grocery stores, to supermarkets selling chicken meatballs. Before the existence of modern meat grinding machines, the process of grinding chicken meat was very difficult, but now, with advances in technology, there are many grinding machines on the market that simplify the process of grinding meat. The business of making and selling chicken meatballs has attracted the interest of several community business groups with small and medium scale businesses. In order for the business of producing and selling chicken to meet public demand both in terms of quantity and in terms of quality, good planning and management is needed. The design method used includes grinding machine product design. The result of the design that has been done is the output diameter of the meat with a size of 5 mm with the appropriate results (fine on average). Where the diameter of 2 mm and 3 mm produces chicken meat that comes out very slowly and is very smooth and causes the meat to melt and the chicken meat comes out fast and smooth. Thus, it can be concluded that a chicken meat grinder machine can grind 1 kg of chicken meat in 1 minute and the appropriate output hole size is 5 mm with a smooth and fast output of chicken meat
Analisa Analisa Kelelahan Dan Kekerasan Pada Logam Axle shaft Dengan Pengelasan Gesek
No full textThe axle shaft is a component of the power transfer system which often experiences mechanical failure. The purpose of this study was to determine the degree of fatigue and hardness of metal shafts with variations in frictional load as information on friction welding recommendations on metal shafts. The research method used is the experimental method, which is a way to compare specimens with variations in friction welding loads of 2 kg, 4 kg, and 6 kg using the Rockwell method of hardness testing and fatigue testing using a rotary bending machine. From the research results it is recommended that friction welding on metal axle shafts can be carried out with a friction load of 6 kg because from the results of the fatigue test SPBG6 has the highest average fatigue strength compared to SPBG2 and SPBG4. This was reinforced by the results of the SPBG6 hardness test which showed the lowest hardness level for the parent metal at 80.44 HRA

Analisis Karakteristik Pasang Surut Air Laut terhadap Elevasi pada Pelabuhan Perairan Tanjung Uncang
Get PDFThe tidal wave of seawater is one of the critical factors in port planning related to determining elevation. This research aimed to assess the effect of a tidal wave in the planning of port elevation at the Port of Tanjung Uncang so that the ship's estimated time can be determined. The research method is quantitatively based on primary data from PT. Graha Trisaka Industri and field observations. The results showed that the types of tides at Tanjung Uncang port were mixed tides, prevailing semi diurnal, which experienced two high tides and two low tides in one day. The highest sea level elevation (HHWS) occurred at 354.8 cm (+166.2 cm from MSL) and the lowest low sea level elevation occurred at -20 cm (-186.2 cm from MSL)
Experimental and Numerical Evaluation of Mechanical Properties for Carbon Fiber Reinforced Epoxy LY5052 Composite for Prosthesis Structures
No full textCarbon Fiber Reinforced Epoxy is a material that is widely used in the manufacture of prosthesis structures. In this research, the carbon fiber used is plain weave-type carbon, while the matrix used is LY5052 epoxy, LY5052 epoxy has advantages such as low viscosity and long pot life making it possible to manufacture large-sized prostheses. The first step in this research is making specimens using the vacuum infusion method and then cutting the specimens with dimensions referring to ASTM D3039. Furthermore, tensile test experiments were carried out with the results obtained that the maximum stress () was 537.15 MPa. As an evaluation, a tensile test simulation was carried out with Finite element analysis using Abaqus software, the material properties used were the results of a tensile test experiment, in the process the mesh selection was carried out by input sizing control many times this was done to determine the accuracy of the results. The tensile test simulation results with abaqus software are 523.3 MPa when compared to the experimental, the difference is only 2.58%. based on experimental and simulation results, the mechanical properties of the Carbon Fiber Reinforced Epoxy LY5052 Composite material are almost the same, so that in the manufacture of prosthesis the mechanical properties data in this study can be used when performing numerical analysis in the prosthesis design process

No full textthe engine performance is very important at the automotive world, especially on 4-stroke motorcycles, where most people want the engine performance to be better and more economically. In this case to improve engine performance is done by changing the piston on the motor. With a different piston shape can increase the compression ratio. The purpose of this study is to determine changes in compression ratio, torque, power and fuel consumption, after replacing the piston. The test was carried out on a 2006 Honda Tiger, with a standard piston specification with a diameter of 64.5 mm (flat surface) and replaced with a 64.5 mm pro newtech piston (convex surface) by using Pertamax 92 fuel. The results obtained from the comparison of the compression value of 1, 6 : 1, 12.65 ft-lbs of torque, and 2.87 ft-lbs of power so that fuel consumption increases by 5.685
