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

Ships are sea transportation that is often used in Indonesia. However, who would have thought that the transportation would become a case because of the frequent occurrence of accidents. This has been proven from data from the KNKT (National Transportation Safety Committee) which noted that from 2012 to 2017 there had been an increase in accidents in the waters. In fact, according to the National Search and Rescue Agency (Basarnas) in 2020 there have been 878 incidents with victims reaching 4658 people. In this final project, the author makes a prototype of BNWAS (Bridge Navigational Watch Alarm System) equipped with obstacle warning using image processing with the otsu method strengthened by thresholding-based segmentation with inverse technique (TsTN), distance detection using the triangle similarity method, real-time tracking with GPS (Global Positioning System) and the entire system can be observed on the Android application. The Final Project performs several analyzes including performance analysis by calculating the accuracy of the BNWAS alarm system, image detection accuracy, distance detection accuracy, GPS accuracy, overall system testing accuracy and packet loss. The accuracy of each system is very good because the error is below 2%, while for overall system testing has a very good performance with a delay of 179.8 ms and 0% packet loss.

Abstract

Tiga perempat wilayah Negara Kesatuan Republik Indonesia (NKRI) merupakan wilayah perairan.NKRI adalah negara kepulauan dengan jumlah pulau terbanyak di dunia yaitu 17.504 pulau serta mempunyai panjang garis pantai terpanjang kedua di dunia setelah Kanada. Kebiasaan nelayan Indonesia memasuki wilayah perairan negara lain membuat nelayan Indonesia ditangkap oleh penegak hukum negara lain. Kebiasaan nelayan Indonesia memasuki wilayah perikanan Australia kerap menimbulkan pasang surut hubungan kedua negara. Oleh karena itu, dalam penelitian ini dibuat prototipe perangkat yang dapat memberikan informasi kepada nelayan ketika berlayar bahwa posisi kapal melanggar batas perairan negara lain atau tidak. Sebagian besar kapal-kapal nelayan tradisional tersebut tidak dilengkapi dengan alat navigasi yang memadai. Sehingga perlu perangkat yang dapat memberikan informasi dini kepada jika telah mendekati batas zona perairan negara lain. Prototipe dibuat dengan menggunakan Arduino Mega 2560 / Arduino Uno dan GPS Neo-6M. Modul GPS Neo 6M digunakan sebagai penentuan lokasi posisi kapal kapal, posisi kapal latitude (x) dan longitude (y). Kemudian titik-titik pada garis perbatasan garis, data latitude (xi) dan longitude (yi) diinputkan terlebih dahulu dalam mikrokontroller. Mikrokontroller menghitung jarak posisi kapal dengan titik-titik pada garis perbatasan. Dari pengujian dan pengambilan data yang telah dilakukan, diketahui bahwa rata-rata error dengan Arduino Mega adalah 3,19 % dan dengan menggunakan Arduino Uno nilai error (rata-rata) adalah 5,32 %.

Abstract

Calibration is required for various kinds of tools from kitchen tools such as stirrers or mixers to medical tools such as temperature calibration, ECG, blood pressure, and other instrumentation tools to be according to the required standards. In medical devices, a digital tachometer has been used as a calibration support device to measure the speed of objects that rotate in RPM on the centrifuge. Some medical devices are calibrated in km/hour, for example, the ergo cycle and treadmill. Two different devices or a conversion from RPM to km/hour are required. The research aimed to design a measurement device that performed calibration of devices with different units, namely tachometer that can be used to measure speed in RPM and km/hr. Based on the research objective, a tool was made to measure the motor's rotational speed using the E18-D80NK sensor, microcontroller, and LCD without touching the object being measured.

Abstract

Body health is the most important thing for human life. The heart is one of the organs of the body that is very important for humans. The heart functions to regulate the circulation of oxygen-rich blood and to carry leftover food in the body. Heart rate illustrates how hard the heart works. The heart rate needs to be monitored to find out the patient's condition. BPM measurement and temperature is an activity of measuring heart rate and body temperature. The patient’s body temperature affects the patient's rapid heart to pump blood throughout the body.  The study aims to design a heart rate and body temperature measuring device using an infrared LED as a transmitter and a photodiode as a receiver, an LM35 as the temperature sensor, and an LCD to display the final output. This tool uses an ATMega8 microcontroller as the controlling system.  The device was completed with data storage and temperature indicators.  The result of the test on the device showed that the device performed very well in measuring the heart rate and body temperature of adult patients aged 20 until 40 years old.

Abstract

Lack of river and watershed management will cause problems and disasters. One of it is the flood that can cause physical, social and economic loss. So countermeasures or flood anticipation are needed by using the Early Warning System (EWS) to provide early information if a flood is going to occur. This study uses five input indicators: temperature, humidity, water discharge, water surface altitude and rainfall data that will produce output in the form of notifications and alarms for the Early Warning System (EWS). Then the input and output data configuration will be processed using a Backpropagation Neural Network. Data used is data recorded in real-time on the research object for two weeks with the composition of training and testing data with a percentage of 80% and 20%. The best backpropagation neural network model used has the input of 5 neurons layer architecture, 15 neurons as the hidden layer and three neurons as the output layer. The flood prediction result uses the Backpropagation Neural Network method, has an RMSE score performance of 2.16e-21 and a percentage success testing system of 91.33%. It shows that the model has an excellent accuracy level.
