No full textWaste Bank is a business The Enviro\u2718 entity engaged in the social sector that manages and utilizes waste with the aim of maintaining the environment and welfare in the surrounding community. Processes related to activities that can be carried out in the waste bank, such as customer registration, sales of waste, withdrawal of customer balances, preparation of waste sales reports. There are shortcomings in the waste bank process, where all processes are carried out manually and there is no system to facilitate the process. To overcome this, we need a web-based information system that aims to assist in managing customer data and waste data. Making this system using the System Development Life Cycle method with a prototype model. Based on the results of blackbox testing, it can be ensured that the system created can help make it easier for customers to register and view catalogs and make it easier for waste banks to collect waste data and manage data. Broadly speaking, from the test results, all system functionality can run well. This can be proven in process testing and can also be proven in the questionnaire analysis process which shows the functionality of the system that has been built is considered quite good in supporting the processes that run in the enviro\u2718 waste bank

Pengaruh Sudut Sudu Turbin Jenis Taper Terhadap Tip Speed Ratio (TSR) dan Power Coefficient (CP) pada Turbin Angin Horisontal Berbasis Q-Blade
Get PDFThe utilization of wind energy as a power plant still needs to be improved by looking at the turbine performance, which is not always the same in different regional conditions. This study aims to determine the effect of the blade angle of the turbine on the tip speed ratio (TSR) and power coefficient (CP) by using a Q-Blade simulation. Q-Blade software can predict the value of the power generated at the blade rotation by comparing the CP and TSR values. The type of airfoil NACA 4412, taper blade, blade\u27s numbers (4), blade radius (0.3 m), wind speed ± 3.6 m/s were fixed variables in this study. The simulation generated a graph of the relationship between CP and TSR changed and a simulation image of the load distribution ensued in the blade geometry. The blade angle of 30 at the TSR number 5 produced the highest CP values, which was ±0.4. The low loading value in the axis/rotor region, at a variation of the blade angle of 30, balances the centrifugal force on the rotating fluid. The centrifugal force produces thrust on the turbine so that the blade rotates with a high CP value in that area
