Abstract

PLTGU is a gas and steam power plant, producing electrical energy of 3x526 MW. The PLTGU generation process has several supporting components, one of which is a three-phase induction motor. It requires a balanced three-phase supply voltage in its operation. The problem that frequently occurs is unbalanced voltage supply, causing an imbalance of current going to the motor stator, if not directly corrected. It causes a high temperature on the motor, possible to cause a fire. Based on the problems, a system for monitoring the protection of steam pump motorcycles due to voltage unbalance based on the Internet of Things is designed.  It used a 1-phase AC Adapter voltage sensor, a current sensor SCT-013, an Arduino Uno as the processor, and a web to display the system. The test results showed that the sensor could work well. It could read voltage with an error percentage not exceeding 1%. The percentage error of the current sensor SCT-013 was 5.15%, but the value difference between the sensor and the Avo meter was 0.01. The system was displayed on the web to make to monitor the motor condition more easily

Abstract

Kebutuhan teknologi kapal di zaman yang terus berkembang harus diimbangi dengan inovasi akan peningkatan fungsi teknologi. Air kotor yang ditampung dalam tangki pembuangan di kapal berupa kotoran manusia, cairan medis, air bekas laundry dan dapur, dan air hasil pemisahan oli. Pembuangan air kotor yang masih manual di beberapa kapal, diupayakan untuk dijadikan otomatis. Penambahan sensor akan mempermudah awak kapal dalam memantau level volume yang terisi di tangki pembuangan air. Pembuatan purwarupa membutuhkan kalibrasi sensor yang digunakan yaitu sensor ultrasonik JSN-SR04. Cara kalibrasi yaitu membandingkan hasil pembacaan sensor JSN-SR04 dengan alat ukur penggaris. Untuk memastikan akurasi pembacaan sensor maka dilakukan kalibrasi. Kalibrasi pengukuran jarak obyek menggunakan pembanding berupa penggaris. Hasil Pembacaam Sensor Ultrasonik JSN-SR04 dapat berfungsi sesuai yang dibutuhkan saat diletakkan di atas tangki purwarupa. Aktuator berupa pompa dan solenoid bekerja sesuai dengan program yang dibuat. Permukaan air yang tidak rata akibat guncangan dapat mempengaruhi pembacaan nilai sensor ultrasonik. Sistem sebaiknya ditambahkan komponen notifikasi seperti alarm buzzer atau lampu sebagai penanda air kotor telah dibuang atau tangki sedang kosong.

Abstract

The Minimum Competency Assessment is one of the national assessments used in 2021 by the Ministry of Education and Culture to replace the high school level national exam. It focuses on measuring literacy and numeric skills through students' logical abilities and reading comprehension. To trigger an increase in logic skills, SMAN 1 Lumajang students are given additional knowledge outside the curriculum. One of them is through the introduction of microcontrollers and PLCs, namely logic-based programming devices. This activity is also able to increase digital, technological and human literacy competencies in the era of the industrial revolution 4.0 because Microcontrollers and PLCs are widely used in the field of industrial automation. From the implementation of the activity it is known that the results of the participants' quizzes on each subject matter showed very satisfactory results with an average score of 76 and the results of the participants' tests at the end of the lesson also showed satisfactory results with an average score. out of 74. In addition, the results of the participant questionnaire in response to the implementation of the activity showed very good results. With these activities, the microcontroller and PLC can be used as one of the extracurricular activities to improve the competence of SMAN 1 Lumajang students.

Abstract

Udang merupakan salah satu komoditas budidaya unggulan di Indonesia, hal ini dapat dilihat dari tingginya permintaan pasar terhadap udang, baik di pasar lokal maupun dari pasar internasional. Salah satu contoh jenis udang yang banyak dibudidayakan di Indonesia adalah udang vaname (Litopenaeus vannamei). Udang vaname atau disebut juga udang putih merupakan spesies udang yang berasal dari Amerika Tengah dan Selatan, seperti Ekuador, Venezuela, Panama, dan Brazil. Selama ini di IBAP (Instalasi Budidaya Air Payau) Banjar Kemuning proses pengukuran parameter air secara manual dan tidak teratur mengakibatkan keterlambatan penanganan udang sakit. Melihat kondisi tersebut, penelitian ini akan membuat sistem yang mampu memantau dan mengklasifikasikan kondisi kualitas air pada tambak menggunakan metode fuzzy dengan parameter berupa pH, suhu, DO, TDS, dan kekeruhan air. Hasil klasifikasi dan pembacaan nilai parameter akan dikirimkan ke website. Berdasarkan hasil pengujian metode fuzzy rata-rata error pada toolbox Matlab dibandingkan Arduino adalah 1,06%. Sedangkan pada pengujian fuzzy menggunakan perhitungan manual dibandingkan dengan hasil pengujian pada toolbox Matlab terdapat error sebesar 0,44%

Abstract

The utilization of the Crushing and Barge Loading Conveyor (BLC) systems is important in coal processing. A crushing system is required as a tool for the process of crushing coal into smaller sizes and then transferring it to the stockpile. While a BLC system is needed to transport coal from the stockpile to the barge. In general, the control and supervision systems for crushing and BLC systems are carried out separately by two operators. However, the distance between two operators causes a time lag information. In this research, we create a Supervisory Control and Data Acquisition (SCADA) system with the type of Multiple Programmable Logic Controller (PLC) on the Crushing and BLC systems using Profinet communication integrated by two PLCs with one Human Machine Interface (HMI) and WinCC. The system is equipped with real-time data, automatic control, and online surveillance with smartphones via the S7APP application. The error resulting from the reading of each component by the HMI and smartphone reaches 0%, while for automatic control, the system works very well, having a success rate of 100%.
