PERANCANGAN MESIN PENGAYAK DAUN KERING BAHAN BAKU PUPUK ORGANIK DI CV. GLOBAL BUMI PUTRA DENGAN PENDEKATAN METODE PAHL AND BEITZ

In the current condition of more advanced technology, all activities will be easy with the emergence of various new tools that have more usability than the basic capabilities of the previous tools.  The more sophisticated the tool, the lighter the work done during the production process.  CV. Global Bumi Putra, one of the organic fertilizer factories in the city of Jember, is still carrying out the sieving process in a traditional way.  To increase the yield of dry leaf organic fertilizer, a dry leaf sieving machine was made.  The method used to design this machine is the Pahl and Beitz method.  There are 4 design stages in this method, namely planning and explaining tasks, designing product concepts, designing product forms, and the final phase of detailed design.  From the results of the design using the Pahl and Beitz method, the design of the dry leaf sieving machine with the machine frame uses iron material, in the form of a cube for the outside.  AC motor drive with electrical energy sources, transmission using belts and pulleys.  Minimum machine design with size P = 2 m, W = 1.5 m, T = 2 m.  The sieve on the machine is tubular, the size of the sieve net is 4 cm.  The average yield of 2 sacks of chopped leaves using a manual sieve was 5.36 kg in 10.31 minutes.  Meanwhile, from the test results of the sieving machine that was made, the average sieve yield of 2 chopped leaf sacks was 5.92 kg in 03.49 minutes.
