Belt conveyor is a fairly simple equipment used to transport load units or bulk materials with a large capacity, the tool consists of belts that are resistant to the transport of solid objects. The sabuk used in this Belt Conveyor is made from various types of materials, for example from rubber, plastic, leather or metal which depends on the type and nature of the material to be transported.
The testing process of this tool starts by turning on the Conveyor Belt, the rotation on the Conveyor Belt is constant at a speed of 3.1 m / min and there is no speed setting, the speed of the Conveyor Belt can be known using the Tachometer tool and can be calculated manually using the formula v = s / t where v = speed, s = distance and t = time. When the object is attached to the Conveyor Belt the object will run and pass through the Ultrasonic sensor, when the position of the object is directly under the sensor, the sensor will detect the object based on the height or distance between the sensor and the object, so that Arduino Uno can carry out the work process of the object falls into category A, B or C.
Nowadays, energy sources in the world at the end until now tends to be filled using fossil fuels. It is estimated that the world energy consumption until 2025 is still dominated by fossil fuels, namely oil, natural gas and coal. The Ministry of Energy and Mineral Resources said that petroleum dominates 54% of energy use in Indonesia. One way to overcome the use of fossil energy sources is to replace them with renewable energy especially photovoltaic. Therefore, this paper presents solar charge system using Buck Converter PID Controller for Spotlight load. Buck Converter with PID Controller is used to produce a smaller and more stable output voltage from solar panels of 14.4 Volts for charging the battery. The PID parameter values ??obtained after performing calculations using the Analytic Tuning method and tuning are Kp = 0.0307, ??Ki = 58.20 and Kd = 0.000263. The expected result of this research is to design and implement a solar charge controller as a producer of electrical energy from environmentally friendly energy.
5S is a work culture from Japan that is easy to apply in daily activities, the 5S concept is simple so that it is easy for anyone to understand and understand. The introduction of 5S to Trimitsa Plus Vocational High School students was preceded by introducing what S consists of five parts, namely Seiri, Seiton, Seiso, Seiketsu and Shitsuke. The implementation of community service activities for SMK Plus Trimitsa students is a form of the JGU campus' contribution to the surrounding environment. This activity involved JGU campus students and lecturers who served as material presenters, escorted educational games about 5S and also helped implement 5S in the SMK Plus Trimitsa workshop. Students of SMK Plus Trimitsa are given the opportunity to ask questions and answers about 5S so that they can have the same understanding as the presenter of the material and games related to 5S, namely the game of arranging numbers and letters from boxes containing scattered numbers and letters. The aim is for students to be able to understand that there is a difference between messy and tidy working conditions where if a messy work environment will make it difficult for us to work.
Pemilihan arus pengelasan yang mempengaruhi hasil pengelasan adalah parameter pengelasan, kualitas hasil pengelasan di pengaruhi oleh energi panas yaitu arus las. apabila pemilihan arus las yang kurang tepat maka hasil pengelasan tidak akan teratur, melebar dan tidak rata. Penelitian ini bersifat eksperimen suatu cara untuk mencari hubungan sebab akibat antara dua faktor yang saling berpengaruh. Dengan melakukan pemeriksaan dan pengujian hasil las dengan arus pengelasan terhadap sifat-sifat mekanik hasil las pada poros tekuk baja st. 37 dan st 41 pada perancangan alat penekuk behel manual dengan menggunakan jenis las SMAW DC 400 G dan memakai jenis elektroda E7016 diameter 2,6 mm
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
