In the industrial era 4.0, the automation system technology used is growing rapidly. Automation systems in the industry are very useful, especially in reducing production time. One of the tools that can be used to simulate production in an industry is the Modular Production System (MPS). MPS itself consists of several stations to simulate the production process on a small scale. In a production system, of course, a system is needed that can detect abnormal workpiece conditions. This system will be driven by a Programmable Logic Controller (PLC). This system will be placed at the distribution station. The rejection system in MPS is needed because, in MPS there is still a manual process, namely in the process of inserting workpieces into the stack magazine. with this manual process, it is likely that workpieces with abnormal conditions will be processed by MPS. This condition is unlikely to be processed further to the pick and place station. Therefore, objects with abnormal conditions must be separated by this rejection system. There are 2 methods used to conduct this research, namely using the 5/3 valve and the positive stop method. Data collection from both methods is done by experiment. From the experimental results of the two methods, it can be seen that the best method used for this system is the positive stop method. This method is the most appropriate method because it can produce a very accurate swivel arm stop position. From the data obtained, using the 5/3 valve method with a pressure of 4 bar the swivel arm stop position ranges from 22.4 cm to reach more than 25.8 cm, and at a pressure of 5 bar the swivel arm height ranges from 25.8 cm to more. By using the positive stop method the swivel arm stops exactly at the specified swivel arm height because the swivel arm is held by the pneumatic cylinder.

Modular Production System is a station unit consisting of industrial components in the form of pneumatic and electrical components controlled by a Programmable Logic Controller which is directed for industry-oriented vocational training. In a Modular Production System, there are several types of stations, one of which is the pick and place station which consists of two modules, namely the pick and place module and the conveyor module. This design discusses the optimization of the design of the top cover feeding unit at the pick and place station because the top cover is dislocated every time there is a change in position when the vacuum sucks the top cover. This design optimization is done by redesigning the feeding unit slider. By doing this optimization, it can make the feeding unit accommodate the top cover where it should be and improve the process capability of the system. The results of this optimization are determined based on the process capability values, before optimization the resulting values were 1.0417 for Capabiity Process and 0.77 for the index. Then after design optimization, the values are 3.402 for Capabilty Process and 6.396 for the index and produce a total force of 0.205 N by using a slider feeding unit tilt angle of 14o. This tilt angle was determined as the most optimal angle because it resulted in the least system failure.

Impeller adalah komponen utama pompa sentrifugal yang sering mengalami kegagalan seperti erosi, korosi dan kavitasi. Untuk mencegah kegagalan tersebut, salah satu cara yang digunakan adalah memberikan pelapis dengan metode TWAS. Pada penelitian yang telah ada, coating dengan metode TWAS menjadi salah satu pilihan yang banyak digunakan, namun belum banyak penelitian yang membahas mengenai pengaruh pengulangan sandblasting pada coating metode TWAS. Penelitian ini bertujuan untuk mengetahui pengaruh pengulangan sandblasting pada impeller pompa berbahan baku stainless steel 304 dengan metode Twin Wire Arc Spray Coating dengan NiAl sebagai bond coat dan FeCrBSiMn sebagai top coat. Penelitian ini menggunakan spesimen tanpa diberikan pelapisan dan spesimen tebaik yakni yang diberi pelapisan dengan satu pengulangan sandblasting. Karakterisasi dilakukan untuk mengetahui kekasaran permukaan (ISO 8503), kekerasan lapisan (ASTM E384), coating (ASTM D4541), dan laju korosi (ASTM G102). Pengujian SEM dan analisis ImageJ dilakukan untuk mengetahui struktur lapisan. Hasil penelitian menunjukan sandblasting dengan satu pengulangan memiliki hasil kekasaran permukaan dan ketebalan lapisan terendah. Namun, memiliki hasil karakterisasi lapisan paling optimal dengan porositas dan unmelt terendah, kekerasan tertinggi dengan 1081.6 HV dengan coating yang sudah sesuai dengan standar yakni 14.5 MPa dan semakin banyak pengulangan sandblasting, semakin tinggi laju korosinya. Kesimpulan dari penelitian ini adalah satu pengulangan sandblasting dalam metode TWAS sudah memberikan kualitas terbaik yang dapat meningkatkan performa dan penggunaan impeller pompa.
