Abstract

Perkembangan industri telah memasuki era industry 4.0. Salah satu teknologi di era ini adalah yang dikenal dengan Internet of Things (IoT). Industri dituntut untuk dapat beradaptasi dengan teknologi baru ini, termasuk industri proses. IoT membawa konsep fleksibilitas, efisiensi dan produktifitas melalui teknologi informasi yang cerdas berbasis internet. Proses yang sebelumnya hanya dapat dikendalikan dan dipantau melalui ruang kontrol dengan komunikasi serial berbasis kabel, saat ini ditutut untuk dapat dikendalikan dan dipantau kapan saja dan di mana saja dengan komunikasi berbasis internet. Dalam penelitian ini, kami membangun prototype satu lup sistem kontrol proses level dengan kontroler utama menggunakan mikrokontroler ATmega328p. Kontrol PID diimplementasikan ke dalam algoritma mikrokontroler yang terintegrasi dengan ESP3286 sehingga pengendalian dan pemantauan dapat dilakukan di mana saja dan kapan saja via Human Machine Interface (HMI) berbasis website. Pengujian pada prototype menunjukkan hasil yang menjanjikan dengan karakteristik respon sistem kontrol: zero offset, maximum overshoot 3 cm dan settling time sekitar 125 detik. Penggunaan website sebagai HMI dapat berjalan dengan baik dengan waktu tunda maksimal sebesar 3 detik jika dibandingkan transfer data dengan komunikasi serial.

Abstract

Sistem kontrol bertingkat merupakan salah satu skema kontrol yang banyak digunakan di industri proses. Skema kontrol ini menawarkan respon terhadap gangguan yang relatif lebih baik jika dibandingkan dengan sistem kontrol single-loop. Dalam penelitian ini, peneliti melakukan desain dan implementasi sistem kontrol bertingkat untuk level fluida (primary loop) dan aliran fluida (secondary loop). Kontroler fuzzy-PID dirancang untuk primary loop sehingga kecepatan respon primary loop. Kontroler Fuzzy-PID adalah kontroler PID yang dapat ditala oleh kontrol logika fuzzy. Parameter PID dapat dirubah oleh keluaran kontrol logika fuzzy  berdasarkan setpoint yang diberikan. Sistem kontrol hasil rancangan diuji dengan simulasi dan diimplementasikan dalam bentuk prototype berbasis Arduino. Hasil pengujian pada prototype menunjukan hasil yang menjanjikan: respon zero overshoot dan zero offset dengan settling time yang berbeda-beda menyesuaikan setpoint yang diberikan.

Abstract

Energy usage is constanly increasing with regard to technology invention, equipment number growth and people growth. So, we have to do energy conservation. The first step in energy conservation implementation is energy audit. By doing energy audit, we are able to identify energy saving potential in audit object. In this paper, we provide a study case of energy audit in office building in Indonesia performed on 2018. This office building has an area of approximately 1.120 m2 with Rp 10,889,658 of average of energy use per month. Energy audit had performed on electricity system, air conditioning system, lighting system dan energy management system. Energy usage profile had been identified and modeled using linear approximation so the main factor of energy usage can be known. Energy saving potential that can be obtained is about 2.358 kWh (30,45%) with Rp 2,431,359 of cost saving approximation per month or Rp 29,176,308 per year.

Abstract

Custody transfer is an important activity in the oil and gas industry which requires high accuracy. In keeping the metering system in an accurate condition, dynamic testing is needed as an evaluation of the custody transfer metering system. In carrying out dynamic testing, software is needed so that calculations will be more accurate and minimize errors. Calculation software in the market is currently quite expensive and does not cover all the calculation needs needed in the field, it is necessary to make calculation software that suits your needs and has a low price. With this software, it is hoped that it can simplify the calculation process and speed up troubleshooting time when there is a measurement deviation because the data read in the flowcomp can be directly proven for its accuracy. In finding a correction factor, a method is needed that is able to determine the value between two known values. Fuzzy method is considered capable of solving these problems. Sugeno fuzzy method is suitable for use in this study because it has an output in the form of a constant. After testing several random samples, the results of the Sugeno fuzzy method have the greatest error on the MPMS API table, namely 0.00004. When compared with the interpolation method, the fuzzy method has the same results as the value generated by the interpolation method. So it can be concluded that the fuzzy method can be used as a calculation method in finding the correction factor.

Abstract

Kebutuhan listrik semakin lama semakin meningkat dengan adanya penambahan-penambahan peralatan elektronik didalam sebuah rumah,tempat kerja, institusi swasta atau pemerintah oleh karena itu timbulah sebuah masalah bagaimana kita bisa memantau pemakaian energi ini secara real time.Sistem ini terdiri dari bagian hardware yang terdiri dari sensor yang berfungsi untuk mensensing variabel listrik seperti arus, tegangan, frekuensi, daya sedangkan controller berfungsi untuk memproses beserta melakukan perhitungan data dari sensor. Kemudian controller mengirimkan data hasil pengukuran ke database MYSQL yang ada di cloud server. Sistem aplikasi berbasis website dan mobile ini menampilkan data-data hasil pengukuran energi listrik yang ditampilkan dalam bentuk grafik beserta informasi lainya menggunakan pemrograman PHP dan aplikasi blynk sehingga kita bisa memonitoring pemakaian energi listrik secara realtime menggunakan jaringan internet.

Abstract

A temperature control system is required in any situationthat requires a certain temperature to remain stable.Likewise, in the electrical processtank heater that requires a control system, because the temperature is notby the set value will cause overheating it,causing the product temperature is not as desired and can even causea dangerous explosion. In this project, the design is carried outtemperature control on the prototype electrical tank heater usingPLC Nano V5.2 as the controller, and the control method used is fuzzy Sugeno.Fuzzy logic has a value of obscurity and obscuritybetween right and wrong and control systems. Membership value may varyfrom 0 to 1. This means a situation can have two values, “yes or no” and "right or wrong", so it seems as if there is a "gray" area. Fuzzy Sugenois a fuzzy inference method for the conditions represented inthe form of IF–THEN, where the system output is not a fuzzy set but a constant form. Test results on the prototype confirm that the systemcontrol with PLC as controller and fuzzy as control methodhas a good ability to adapt the time needed totake longer to reach a stable state at higher temperatures (33.5°C to 37°C).Then at lower temperatures (29°C to 33.5°C). Haiwell-capable interfaceschange set values, display real-time graphs, and send commands toset PWM.

Abstract

In dealing with era society 5.0, a gas company uses the Automatic Meter Reading (AMR) system, which is a remote data reading automation technology system for measuring instrument data in the field, which then conveys the information to the center via communication media data. In the Metering/Regulating Station (M/RS) installation, AMR is connected to the Electronic Volume Converter (EVC) which functions to transmit data from measuring instrument readings in the EVC to the data collection server. The modem on the AMR system uses a power supply from the solar panel system during the day and a battery system at night. The system for handling incomplete data disturbances is currently still in corrective action due to the unavailability of a solar panel monitoring system in the AMR system, causing difficulties for the team in conducting root cause analysis due to problems with battery voltage which are unable to cure AMR. To change the operation and maintenance activities of the AMR system, which was previously corrective action into preventive action, the authors will design and build a long-distance integrated solar panel monitoring system at AMR with the following features monitoring temperature, voltage, and current modules of solar panels, monitoring temperature and battery loading, and AMR remote restart function.
