Abstract

Abstract— The transfer of goods from one place to another in the production process in a common industry we encounter using conveyors. Conveyors have replaced human labor used in moving production goods from one place to another in the industry. By using conveyors, the transfer time can be reduced and not dependent on humans anymore. Conveyor control can use a controller in the form of a PLC. PLC programming can use many methods, one of which is the cascade method. The beginning of the development of this method is widely used in pneumatic systems, but as time goes by this method is used in completing sequential systems. The ideal cascade method is used for sequential processes without an iterative process, the theory is easy to understand, the results are easy to implement. In this study the type of PLC used is CPM1 from OMRON. By using Cascade method, the result from construction of ladder diagram is obtained by 59 rung, 6 timer, 18 relay, and the program capacity is 3 KB.Keywords: Conveyor, PLC, Ladder diagram, Cascade method, relay group.

Abstract

In a pressure process control system when the system is loaded or when the load is released from the system, there will be a change in the system response form. Changes in the form of the response because the load or release of the load changes the dynamics of the system. In the controller industry commonly used are conventional PI or PID. However, due to the large variations in load, the PID controller is unable to meet the specifications. Adaptive settings are one of the regulatory methods in which controllers can respond to modify their behavior due to changes in dynamics due to loading and characteristics of interference. Self-Tunning Regulator (STR) is an adaptive arrangement scheme. Parameter estimation is one part of STR. In this paper the implementation of STR with parameter estimation using the neural network approach (NN STR) is carried out on the pressure regulation system in the Process Rig 38-741. The test results showed that the nominal load condition of NN STR with learning rate = 25 had the closest performance to the design results with a overshoot value of 23.7% and the settling time of 283.8 seconds was in accordance with the specifications of the desired range. In testing with the condition of changes in NN STR load with a learning rate = 20 shows the best performance against all the criteria used. While for testing the nominal load on the variation of NN set-point STR with learning rate = 10 shows the best performance on all the criteria used.Keywords:artificial nerual network, PI, pressure process rig 38-714, self-tuning regulator.

Abstract

In industry, conveyor is a means of transportation to move production materials. Conveyor not just move the goods but there are other processes such as counting the number of goods, filling the liquid and so forth because it is equipped with certain sensors and actuators. These processes can be automated by using PLCs as controllers by executing instruction programs in the form of ladder diagrams. The complexity of automation processes in conveyors requires the use of many relays in PLC programming and is difficult to apply to low-specification PLCs. Of course the procurement of PLC with high specifications require a lot of money. In order to overcome these problems it is necessary a method that can minimize the number of relays used so that the program becomes shorter. By using state diagram, the result of construction of ladder diagram is obtained by 32 rung and the program capacity is 3 KB.Keywords: Conveyor, Flow-Table/State Diagram, Ladder Diagram, PLC, Rung.

Abstract

Ketidakpastian dalam aplikasi kontrol kemudi tidak dapat dihindari. Apabila ada perubahan parameter atau gangguan lain pada sistem, kontroler dapat menjadi tidak stabil. Desain kontroler yang diajukan berupa Linear Quadratic Tracker (LQT) untuk kemudi lateral mobil otonom dengan adanya ketidakpastian internal dari parameter massa, momen inersia, dan konstanta kekauan menikung, sehingga hasil dari penelitian ini diharapkan kontroler lebih robust terhadap ketidakpastian dan tetap dapat mengikuti input yang diberikan. Kontroler yang diajukan sudah robust terhadap variasi parameter massa dan momen inersia akibat pembobotan serta konstanta kekakuan menikung untuk roda depan dan belakang akibat perubahan tekanan udara dan ketebalan roda. Kontroler yang dijaukan juga dapat mengikuti input yang diberikan dengan eror kecil dengan adanya ketidakpastian parameter.

Abstract

Konten ceramah agama adalah salah satu topik yang sangat populer dan berpengaruh besar terhadap pola pikir masyarakat. Pesantren Raudlatul Ulum 1 Suramadu diasuh oleh seorang ulama yang memiliki kapasitas keilmuan tinggi yaitu K.H. Ma’kruf Khozin. Beliau saat ini menjadi ketua bidang fatwa MUI Jawa Timur. Ceramah-ceramah beliau sangat berbobot, mencerahkan, menarik dan mudah difahami. Ceramah tersebut banyak membahas fikih agama Islam dari berbagai sudut pandang. Masalahnya adalah masih sedikit dokumentasi dalam bentuk video apalagi yang diupload pada kanal YouTube. Kendala utama dari masalah tersebut adalah kurangnya sarana perekaman video, sistem pengolah dan pengunggah video ke kanal YouTube yang baik dan mudah dioperasikan oleh santri pondok pesantren dimana notabene kurang mengenal teknologi. Pada pengabdian masyarakat ini kami akan menghibahkan sebuah studio mini. Studio ini merupakan sebuah desktop komputer yang dilengkapi dengan peralatan audio dan video untuk perekaman dan dipacking dalam sebuah mini troli sehingga mudah dipindahkan. Software pengolah video menggunakan jenis open source yaitu Open Broadcaster Software (OBS) yang sangat mudah dan tidak berbayar. Topik ini sesuai dengan satu dari 17 tujuan Peta Jalan dan Tema Ungulan Pusat Kajian Pembangunan Berkelanjutan (SDGs) 2023 yakni Pendidikan (Education),yaitu menjamin pendidikan yang berkualitas, inklusif dan adil, meningkatkan kesempatan belajar bagi semua. Studio mini ini digunakan untuk merekam dan mengunggah ceramah ustadz-ustadz di Ponpes Raudlatul Ulum 1 Suramadu ke kanal sosial media, sehingga menambah jumlah referensi video pembelajaran agama bagi masyarakat Indonesia dan dunia sehingga meningkatkan toleransi dalam beragama dan antar umat beragama.
