There are many advanced technological discoveries in industry, including the coupled tank. Coupled tanks are several tanks connected to each other. One of the quantities that is often controlled in the industry is the control of water levels. Water level control in a PLC and IoT-based coupled tank system is a medium for controlling and monitoring water levels remotely in real-time. The sensor used is a Differential Pressure Transmitter (DPT) with a pump motor actuator which is connected to an Omron PLC using an inverter. There is a disturbance in the form of setting the control valve opening. The control method used is the PID method with Ziegler-Nichols tuning and trial and error. Both methods analyzed which performance of the system response characteristics was better. It is proven that PID tuning is suitable for water level control of coupled tank systems.

ABSTRAK SistemScada merupakan sistem yang sudah banyak digunakan untuk mengontrol dan memonitoring mesin-mesin di dunia industri, tetapi kontrol dan monitoring tersebut umumnya dilakukan disatu tempat saja. Pada perusahaan yang mempunyai plant-plant yang tersebar di lokasi yang berjauhan, banyak mengalami kesulitan dalam mengontrol plant-plant tersebut. Contoh pada mesin boiler, mesin yang memerlukan pengawasan yang lebih ketat karena mesin ini dapat menimbulkan ledakan jika terjadi kesalahan pada sistem. Perencanaan dan pembuatan penelitian ini membuat simulasi HMI scada untuk mengontrol dan memonitoring pada mesin boiler berbasis web gate yang terhubung melalui komunikasi sistem wireless LAN dan untuk softwere HMI menggunakan Vijeo designer. Dengan menggunakan sistem ini, bahkan sebuah PC yang hanya memiliki IE (Internet Explorer) dapat mengontrol dan memonitoring dimana saja selama masih memiliki jaringan web server. Untuk metode yang diterapkan penulis menggunakan metode eksperimen dengan melakukan pengujian sistem HMI scada berbasis web gate serta menganalisa jarak jangkauan jaringan komunikasi. Dari hasil pengujian dan analisa didapatkan bahwa sistem sesuai dengan perencanaan serta jarak jangkauan jaringan komunikasi maksimal 20 meter. Kata kunci:HMI, Scada, Web gate, Vijeo designer, PC Scada system is a system that has been widely used to control and monitor machines in industry, yet typically they both done concentrated in one place only. When a company has plants that scattered in some distant locations, it will be rather difficult to control the plants. For examples in boiler engines, machines that require more strict supervision because these machines can cause an explosion in case of system errors. This research make HMI scada simulation to control and monitor a web-gate-based boiler machine which is connected via wireless LAN system communication and for HMI softwere using Vijeo designer. Using this system, even a PC which only have IE (Internet Explorer) can do control and monitor anywhere as long as it still has a network web server. The method applied by the author is an experimental method by testing the HMI scada system based on web gate as well as analyzing the distance of network communication range. The results shows that the system is well-performed and the maximum distance network communication coverage is 20 meters. Keywords: HMI, Scada, Web gate, vijeo designer, PC

Pertumbuhan jumlah kendaraan mengakibatkan terjadinya peningkatan kepadatan lalu lintas yang menjadi salah satu faktor penyebab kemacetan. Salah satu cara untuk mengatasi kemacetan adalah dengan membangun suatu rekayasa sistem pengendalian lampu lalu lintas berdasarkan kepadatan kendaraan berbasis visual. Penelitian ini bertujuan untuk merancang dan mengimplementasikan pengendalian lampu lalu lintas menggunakan logika fuzzy yang terdiri dari tiga modul fuzzy: modul next phase, stop phase, dan switch phase yang berfungsi untuk memperpanjang atau mengakhiri fase yang sedang aktif dan memilih fase selanjutnya yang akan diaktifkan berdasarkan jumlah kendaraan, lama waktu hijau, dan lama waktu merah. Pengendalian lampu lalu lintas menggunakan logika fuzzy dirancang dan diimplementasikan pada mikrokontroler ARM Cortex-M4 (STNucleo F401RE) yang diintegrasikan dengan traffic monitoring menggunakan komunikasi serial. Traffic monitoring dibuat menggunakan Microsoft Visual Studio yang berfungsi sebagai pengolah citra lalu lintas untuk mendeteksi jumlah kendaraan di setiap jalur persimpangan dan sebagai user interface untuk memonitoring pengendalian lampu lalu lintas. Hasil penelitian menunjukkan bahwa kendali logika fuzzy berhasil menghasilkan lama penyalaan lampu hijau dan urutan fase berdasarkan jumlah kendaraan, lama waktu hijau, dan lama waktu merah. Kendali logika fuzzy dapat memperbaiki performansi kendali fixed-time pada pengendali lampu lalu lintas sebesar 28,21%. Kata kunci― pengendali lampu lalu lintas, kendali logika fuzzy, mikrokontroler, traffic monitoring Growth in the number of vehicles resulted in an increase in traffic density which became one of the causes of traffic congestion. One of the ways to overcome traffic congestion is through the development an engineering system of traffic light controller based on vehicle density. This research aim to design and implement a traffic light controller using fuzzy logic which consists of three fuzzy modules: next phase module, stop phase module, and switch phase module that serves to extend or terminate the current active phase and selecting the next green phase which will be activated based on the number of vehicles, the length of green time, and the length of Red Time. Traffic light controller using fuzzy logic was designed and implemented in ARM Cortex-M4 microcontroller (STNucleo F401RE) which was integrated with traffic monitoring using serial communication. Traffic monitoring was made using Microsoft Visual Studio that serves as a traffic image processing to detect the number of vehicles in each lane of intersection and as a user interface for monitoring the traffic light control. The results showed that fuzzy logic control success to generate length of green light and phase sequence based on the number of vehicles, the length of green time, and the length of Red Time. Fuzzy logic control improved the performance of fixed-time control on traffic light controller of 28.21%. Keywords: traffic light controller, fuzzy logic control, microcontroller, traffic monitoring

Metode kontrol Proporsional-Integral-Derivative (PID) banyak diterapkan di bidang industri. Kontroler ini memiliki parameter-parameter pengontrol, yaitu Kp, Ti, dan Td. Ketiga parameter tersebut diturunkan dari perhitungan matematis pada metode PID konvensional. Kesulitan timbul bila plant yang dikendalikan adalah sistem dengan orde tinggi. Maka dari itu, diperlukan metode penalaan PID yang dapat diterapkan dalam sistem orde tinggi. Metode Ziegler-Nichols merupakan sebuah metode penalaan PID yang dapat dilakukan secara otomatis tanpa memodelkan sistem. Pada penelitian ini dirancang kendali P, PI, dan PID pada pengaturan kecepatan motor DC menggunakan penalaan ziegler-nichols. Hasil penelitian menunjukkan bahwa risetime, settling time, dan maksimum overshoot pada kendali P tercapai lebih kecil dari kendali PI tetapi pada kendali P masih terdapat error steady state sedangkan pada kendali PI error steady state sudah dihilangkan. Sedangkan pada kendali PID dengan Kp = 175.44, Ki = 4408.22, dan Kd = 1.746 dapat mencapai error steady state (0%), risetime (0.00467s), settling time (0.0404s), maksimum overshoot (9.9%) yang lebih kecil dari kendali P dan PI dan memenuhi spesifikasi sistem yang telah ditentukan. Kata kunci: P, PI, PID, Motor DC, Ziegler-Nichols PID (Proportional-Integral-Derivative) control methods nowadays are widely applied in industry. This controller has control parameters, ie Kp, Ti, and Td. These three parameters are derived from mathematical calculations on conventional PID methods. The difficulty arises when the controlled plant is a system of high order. Therefore, a PID tuning method that can be applied in a high order system is required. The Ziegler-Nichols method is a PID tuning method that can be done automatically without modeling the system. This study designed P, PI, and PID control on DC motor density settings using ziegler-nichols tuning. The results show that the research, settling time, and maximum overshoot on P control is achieved less than PI control but on P control there is still steady state error while on the PI control the steady state error has been eliminated. While at the control of PID with Kp = 175.44, Ki = 4408.22, and Kd = 1.746 can reach steady state error (0%), risetime (0.00467s), settling time (0.0404s), maximum overshoot (9.9%) control P and PI and meet the specified system specifications. Keywords: P, PI, PID, DC Motor, Ziegler-Nichols
