Abstract

This study aims to destroy an automatic egg incubator, where the performance parameters to be monitored are the temperature and humidity of the incubator. The monitoring system uses the Internet of Things (IoT) application. The egg incubator utilizes the lamp's heat to maintain the room temperature's stability. Utilizing the DHT11 sensor, the temperature data will be processed on the Wemos d1 microcontroller, which is then sent to the internet wirelessly. The temperature and humidity data results will be read in real-time using IoT with the Blynk platform, which can also be accessed using a smartphone. The results of this study apply IoT technology to the monitoring system for measuring conditions of the incubator temperature and humidity parameter values. All device modules will be packaged into embedded systems integrated with environmentally friendly IoT innovation rules and support the technological era of the industrial revolution 4.0. The results of measurements at the incubator's location and the monitoring using the Blynk application are relatively the same, and the success rate of hatching eggs reaches 74% of the total eggs put into the incubator

Abstract

Scientific publications are a means of delivering research results and innovations of researchers. Recently, researchers' interest in publishing publications is also increasing. This increase occurred in the publication of papers through scientific conferences. This encourages the need for the use of information technology to facilitate conference management. However, the application of the conference management system is still minimal. Based on these problems, this study proposes a web-based conference management method. The system is built using a MySQL database and Model-View-Controller (MVC) code architecture in PHP. Therefore, every conference process can be included in the system. the system is designed with three main modules, namely the participant/presenter module, reviewer module, and committee/admin module, which covers the entire conference process starting from registration, paper submission, review, payment and distribution of presentation rooms. Trials and evaluations are carried out using the Black Box Testing method to ensure the system can work well. The results of the tests and evaluations that have been carried out show that the proposed system is proven to have good performance with a score of 100% or successfully fulfills all existing test scenarios

Abstract

The protection system is essential in the 20 kV distribution network system. The 20 kV equipment control system is supplied from 2 sources: PT (Potential Transformer) and DC voltage supply (Battery). If the protection relay and mechanics do not get a DC voltage supply, it will have an impact on the equipment not being able to trip when there is a disturbance in the network. There is no DC voltage supply due to battery failure or damage. For this reason, it is necessary to operate the tool manually, which results in the normalization process taking longer because it takes time and long distances, so the duration of outages is even greater. In this study, a monitoring system for the battery of the equipment will be made where previously observations were made about the need for this tool. The method used by the tool uses the blynk application as a receiver of direct voltage and temperature measurement reports that are connected to the gsm module. As a microcontroller processes, Arduino Nano commands from intelligent phones, generating a measurement report from the battery. GSM SIM 900 module as a data receiver and sender in the system. This tool is easy to apply to the system because it does not require a sufficient additional voltage source from the battery. The results of this study become a solution for companies to improve their 20 kV. distribution network system.

Abstract

The heart is an organ that never stops moving, even when humans sleep. The heart rate must constantly be monitored to determine whether our heart rate is average or not. The heart and humans are also not spared from checking body temperature. Because body temperature can indicate the presence or absence of disease in a person's body, in this study, the detector detects heart and body temperature with a monitoring graphic display that makes it easier for users/patients to detect heart detection (BPM) which is equipped with a graphic display and also body temperature which is also on the display screen. The research method used is an experimental method where the tool is made with a standard size of the original tool. Moreover, from the data collection results, it can be interpreted that the tool is feasible to use and follows medical device calibration standards with correction results for heart rate, namely 2.0%, 0.6%, and 1.0%.

Abstract

Predictive maintenance is a treatment for the actual operation of the equipment to optimize the company's operations. The output of predictive program maintenance is data, this treatment includes the type of "condition based maintenance" where changes in the condition of the machine or equipment are detected so that proactive actions are taken before the occurrence of machine damage. The K-nearest Neighbor (K-NN) algorithm is a simple supervised machine learning algorithm that is used to solve problems based on classification and regression. K-NN works by finding the query distance and all database examples, selecting a certain number of examples (K) adjacent to the query, then selecting the frequent label (in classification) or the average label (in regression). The purpose of this algorithm is to classify new object conditions based on attributes and samples from the training database. So that a predictive analysis is carried out on the damage to generating equipment using the machine learning application method of the Nearest Neighbor type or the classification of conditions used to predict the age or condition of an equipment by modeling according to the standard Operation & Maintenance of equipment. By doing predictive analysis, maintenance will lead to condition based maintenance so that the KPI (Key Performance Indicator) of operating performance in the form of increasing values, such as Capacity Factor (CF), Equivalent Availbility Factor (EAF) becomes optimal and prevents the generator from tripping suddenly. which is called sudden outage frequency (SdOF), as well as more efficient maintenance costs.

Abstract

As a provider of electricity services, PLN is required to provide service and supply of electricity with good quality, continuity, improvement and efficiency. Disturbances in distribution systems are short circuit faults between phases or ground phase faults. To protect properly, proper coordination of relay settings is required. Among the equipment in the protection system used in distribution lines are overcurrent relays (OCR) and ground fault relays (GFR). In this study, an analysis of the OCR and GFR settings will be carried out on a 20 kV cubicle at the Sanga-Sanga Substation, East Kalimantan, with the help of the DigSILENT Power Factory 15.1.7 application with a disturbance simulation at 10% and 90% of the feeder length. Based on the analysis results, it is obtained that the short circuit results of 3 phases, 2 phases, and 1 phase to the ground have a value that is not much different from the calculation, while the OCR setting for the outgoing relay is 0.8 A on the secondary side. TMS is 0.083 seconds while the relay is on the incoming side of 20 kV 1 A and TMS of 0.198 seconds. The GFR setting for the outgoing relay is 0.06 A on the secondary side, and TMS is 0.1 seconds, and the relay on the incoming side is 20 kV 0.015 A and TMS is 0.26 seconds).
