Pembuatan Dan Pengujian Mesin Penumbuk Daging Rendang Suir Kapasitas 1kg/Jam
Get PDFRendang is a typical food from Minangkabau that must be present in every custom event in Minangkabau, to improve the quality of the rendang meat, processed rendang meat is processed into processed rendang suir meat to improve the quality of its resistance. At this time the process of making rendang meat still uses a manual process which certainly does not fulfill all the desires of consumers, so the meat rending machine is made with a capacity of 1 kg / minute. This machine functions to pound rendang meat so that fiber from meat looks easier to stir. This machine aims to help the process of pulverizing the rendang meat to become flush. In this machine. The drive system is a fixed clutch, which is connected to one another. Making this frame using ST 37 iron whose dimensions are 350 mm x 550 mm x 700 mm. Whereas for the dimensions of pounding rendang suir meat is 10 mm x 200 mm x 350 mm. How it works rendang meat is placed on the bottom pounder. Then press the male clutch pedal so that there is friction between the male and female coupling so that the pulverization process occurs. After the collision results reach the desired release, step on the clutch pedal, then take the mashed meat. The making of rendang suir meat pounder machine begins with identification and field survey of whatever demands for the needs of producers of rendang suir meat. Then the next stage is the determination of several alternative planning, then the determination of the concept of planning, machine calculation, drawing the planning model
TINJAUAN RASIO KEUANGAN PADA PT. ACSET INDONUSA TBK PERIODE 2013-2016
Get PDFThe financial statements are one of the important sources of information and media used by corporate managers in the decision making process. PT ACSET Indonusa Tbk is the first construction company to offer its shares to the public on June 24, 2013. 2017 PT ACSET Indonusa Tbk acquires infrastructure projects in the form of Jakarta-Cikampek toll road with 49% portion of work. This study aims to analyze the financial ratios of PT. ACSET Indonusa Tbk period 2013-2016. The research method used is quantitative method and descriptive method. The results showed the liquidity ratio of PT. ACSET Indonusa Tbk is in good condition that the company can pay its current liabilities by using current assets, current assets minus inventories and cash. The company's solvability ratio is said to be less good, because it is above average of the industry > 50%, meaning the company's assets are financed by debt. The ratio of activity is below the industry average, it indicates that the use of assets is less good to generate sales. The latter profitability ratios are below average of industry, this indicates that the company is in poor condition, this causes the company must increase profit by reducing costs such as general and administrative costs, final tax costs and financial costs

Alat Pengering Kerupuk Palembang Dengan Menggunakan Gas LPG
Get PDFThis cracker dryer is made considering that there are still many cracker industries that use solar thermal energy directly to dry raw crackers before the frying process, so that the cracker production results will decrease due to inefficient drying process, therefore all obstacles are always experienced when using energy sunlight can be overcome by using a cracker dryer using gas (LPG). This cracker dryer has dimensions of length 550 mm x width of 450 mm x height of 1000 mm and size of drying rack with a length of 500 mm x width of 400 mm x height of 25 mm. This tool has 4 drying racks with a capacity of each rack 1.5 kg. This dryer uses the principle of convection that is utilizing heat energy generated from the heat of the fire produced through a gas-using stove (LPG), the radiated fire produces heat that enters the drying cabinet. Hot air is locked in a drying room, so that the heat can help the drying process of cracker

Analisa Kinematika Monobike Mechanical Toys Menggunakan GNU Octave dan Solidworks
Get PDFIndustry era 4.0 allows the use of cyber technology, both physical and non-physical, in all aspects of life, including the toy industry. 3-dimensional printers as a key technology industry 4.0 plays an important role. Before it is printed using a 3D printer, it becomes a real product ready to be marketed, first the product is simulated to find out if the toy product can move according to the kinematics that we design. This analysis includes the displacement, velocity, and linear and angular acceleration of the Monobike component. In this research, the analysis of component movements is limited to Link 3. In this study, a toy that can mimic the motion of an object as precisely as possible is determined, which is a monobike toy. Monobike mechanical toys mimic human activities of pedaling a bicycle. The methodology in this research is as follows: 1) Determine the dimensions of the monobike component, 2) Determine the monobike drive components, 3) Make a monobike kinematic diagram, 4) Perform kinematic analysis using the position vector of the monobike component, 5) Perform displacement, velocity calculations , and theoretical acceleration with Excel, 6) Perform kinematic analysis with Solidworks, 7) Comparison of theoretical calculation results and Solidworks simulation results. Based on the results of theoretical research and Solidworks simulations, the values of displacement, velocity and acceleration are close. The average error for linear displacement is 0.261%, linear velocity 0.852%, linear acceleration 0.7664%, angular velocity 0.372%, and angular acceleration 0.492%. Kinematic analysis in monobike mechanical toys theoretically using Excel and simulation with Solidworks software, the results are more or less the same, so it can be said that this research is accurate. Solidworks is recommended as software that can be used to simulate movements in kinematic analysis
Pengaruh Tinggi Air Masuk Dan Diameter Pipa Outlet Terhadap Tinggi Air Keluar Pompa Hidram
Get PDFThe pump is a device that can lift water from a lower height to a higher place, but because there are many pumps in the market that use electricity as a power plant and the selling price is quite high for rural communities, an appropriate pump is needed and cheap. Hydram pump is one alternative, where the workings of this tool can raise the water to a higher place with energy or power that comes from the water itself. Making Hydram pumps itself is relatively inexpensive, simple and durable. Hydram pumps are very popular because they work without using energy, so it is suitable for use in villages that do not have electricity. The purpose of this study was to determine the effect of the height of the incoming water and the diameter of the outlet pipe on the height of the outlet water at the hydram pump. In this study the height of the incoming water was varied as high as 0.5m, 1m and 1.5m while the diameter of the aoutlaet pipe was varied by 0.5inc, ¾ inc and 1 inc. From this experiment it was found that the height of the incoming water and the diameter of the outlet pipe significantly influence the height of the outgoing water, of the two factors most influential on the height of the outgoing water is the height of the incoming wate
