No full textPepper powder is currently widely marketed in packaged form. The process of packing pepper manually has several drawbacks. In addition to the speed of the packaging process, there is also the problem of weighing the packaging accurately. This study aims to design and build a tool for automatically filling pepper powder into bottles based on Arduino Nano. Conveyors are used to place bottles precisely at the filling position. The process of filling the powdered pepper automatically starts after the bottle is detected by the photoelectric sensor. A Screw is used to put the ground pepper into the bottle, while the load cell sensor is used to measure the weight of the powdered pepper filling. The performance of this filling system shows that the average duration of filling time is 0.97 seconds per gram, while the accuracy of reading the weight of filling pepper powder has an error rate of 2.78%. Information during the filling process, which includes the weight of the powder that has entered the bottle, the amount of production, and information on the remaining ingredients available in the hopper, can be properly monitored through the HMI display
Towards automatic Maude specifications generation from C functions
Get PDFIn this paper, we aim to contribute to the knowledge about how imperative C functions can be transformed to Maude functional and system modules respectively. Maude is a formal specification language characterized by simplicity, expressivity and good performance. It is a multi-paradigm meta-language based on rewriting logic and equational theories used to specify, simulate and formally verify concurrent and distributed systems. Maude has been used to define the operational semantics of many programming and specification languages. In particular, the addition of this paper is to close the gap between a subset of the C standard language and Maude relying on a transformational approach.

PROSES PRODUKSI STAND GRIPPER MENGGUNAKAN CNC MILLING 3 AXIS TIPE WELLE CV 1060
Get PDFOne of the efforts made in the education sector to increase the need for human resources is to implement a system that can create a workforce that is ready to apply their knowledge in the field of work. To apply the knowledge they have gained while attending lectures, students are given the opportunity to go directly to a company which is usually called an industrial internship. While carrying out industrial internships at Solo Technopark, students are placed in the CNC design and machining section. The stand gripper production process goes through several stages, namely designing product images, creating a numerical control program with Autodesk powermill software, and computer numerical control milling (CNC milling) machining processes. The problem that occurs during the stand gripper production process is that there is very little material gripping due to the size of the initial material which has very little difference with the size of the finished workpiece. The solution to this problem is to ensure strong clamping and the help of parallel blocks so that the material does not move during the execution of the workpiece
