Abstract

Polytechnic is a university that organizesvocational education in various science and technology clusters.The learning process in polytechnic is dominated by practicumthat is 70% and 30% theory. The amount of laboratorypercentage affects the large number of laboratory. Eachlaboratory has a laboratory responsible (technician) in charge ofrecording and monitoring the completeness and condition of thepracticum equipment. Tools and materials used in the process ofpracticum is an asset and laboratory inventory that must alwaysbe maintained and checked the condition of the equipment. InUjung Pandang State Polytechnic (PNUP) in terms of assetmonitoring and practicum inventory is still done manually.Therefore need to make an application to monitor assets andlaboratory inventory, especially on campus two. It is known thatsince 2014 there are three departments that have implementedthe teaching and learning process in two campuses includingseveral laboratories have also been transferred to the twocampuses, such as electrical engineering majors, majoring inbusiness administration and accounting majors. So with thisapplication will greatly help technicians because no longer do thereporting or request tool manually and with this application inmonitoring the condition of the tool is damaged and tools thatneed further improvement more easily and can be quicklyupdated. The creation of this system begins with the needsanalysis, design design as the basis of system development, theright of access consists of technicians of each laboratory andprocurement department on campus one, content creationconsists of laboratory data, checking tools and materials, repairtools and materials and demand tools and materials then printdata laboratory

Abstract

Savonius wind turbines are wind turbines that canoperate at low wind speeds, this type of turbine is very suitable tobe used in several places in Indonesia. The research aims toimprove the performance of the Savonius wind turbine withvariations in the number of turbine blades as well as variations inthe velocity of wind speed. The research method wasexperimental where wind turbine testing was carried out withvariations in the number of turbine blades with number of 2, 3and 4 blades, other variations carried out were wind speed at 3.5;4,5; 5.5 and 6.5 m/s. The study results show that the 2-bladeturbine produces greater rotation, but the torque moment islower than the 3 and 4 blade turbines, this can be seen in the lowefficiency of the 2 blade turbine at low wind speeds with highloading. At 3.5 m / s wind turbines 2 blade turbines haveefficiency that tends to be the same as 3 and 4 blade turbines upto 0.5 N but at loads of 0.6 - 1.2 N 2 blade turbines have lowerefficiency, while at wind speeds of 4.5 - 6.5 m / s 2 blade turbineshave greater efficiency than turbines 3 and 4 blades up to a loadof 1.2 N but if the load is added then the efficiency of 2-bladeturbines can be smaller than efficiency 3 and 4-blade.

Abstract

The obligation of Muslim towards their relatives who died there are four cases, namely bathing, believing, praying and burying. The community considers that there is no need to think about how to care for the body from the beginning to the finish because there are already their own officers. Rhile in a hadist from ‘Aisyah said Rasullah SAW: “Anyone who bathes a corpse and is guarded by trust and cannot be opened (secret) about the protection of the sympathy for the people there hen comes from sin for hs condition. Based on the hadist mentioned the person who mentioned bathe the corpse in priority is his own closest family, then if the family cannot, then other people can do it, while bathing is included in the case of receiving a corpse based on the results of an interview with teacher Madrasah Diniyah Baitul Athfal by agreeing to him about the management of the body, it is expected if it involves family members. Who can use the world od the sunna of the prophet and also in the future can be used as a successor. In Madrasah Diniyah Baitul Athfal involved in the learning process due to shortages in madrasah are short plus students do not have books about the management of bodies or jurisprudence books become obstacles in the process of learning. Teaching lessons for students or instructors. After obtaining data from data collection, .researchers create a system with predetermined and more relevant methods using the Multimedia Development Life Cycle (MDLC) Method. Based on the results obtained for 9352 and included in the category of Good, then the application was validated that can be applied to the research object.
