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).

Abstract

Increased glucose in the blood can cause a buildup so that it cannot be absorbed by all of the body's cells, this problem can cause various disorders in the body's organs. To avoid problems, it is necessary to check the blood glucose level regularly. Monitoring blood sugar levels is currently still using invasive techniques that are painful, non-invasive monitoring is needed. This study develops a non-invasive method to predict blood glucose through image processing. For investigation, several invasive images and glucose levels were taken. Types of samples based on age classification, 20-60 years. For accuracy and simple analysis, 37 images of participants as volunteers, samples were evaluated and investigated under the gray level co-occurrence matrix (GLCM). In this study, an artificial neural network (ANN) was used for all training and hand texture testing to detect glucose levels. The performance of this model is evaluated using Root Mean Square Error (RMSE) and correlation coefficient (r). Clarke Error Grid Analysis (EGA) variance was used in this investigation to determine the accuracy of the method. The results showed that the RMSE was close to the standard value, the regression coefficient was 0.95, and the Clarke EGA analysis: 81.08 % was in the A zone. So that the blood glucose prediction model using the GLCM-ANN method is feasible to apply.

Abstract

Fibre Optics is a delivery medium to connect network points to multipoint. FTTH is a service provided to customers to meet internet needs in terms of voice, data and video (triple play) services. PT. Telkom has standards for determining network eligibility, namely Power Link Budget and Rise Time Budget. With a case study in Bontomanai Village, Bulukumba, it is possible to simulate the design of the FTTH network to measure BER (Bit Error Rate) for system performance. From the results of network design calculations that the Power Link Budget, one of which is the attenuation from STO to the customer, is 25.65 dB, where this value is still feasible because it is still in the standard range of PT. Telkom is 13 – 28 dB. The Rise Time Budget parameter obtained based on the analysis is 0.262 ns which has not yet crossed the NRZ degradation limit of 0.28 ns. Simulations have been carried out using Optisystem software to measure BER

Abstract

       PLTGU Sengkang which is operated by PT. CEPA Sengkang with a total capacity of 315 MW. One of the important components in the PLTGU system is a generator. In a generator there are many problems that arise, including generator efficiency problems. The research that will be carried out is to determine the generator efficiency value and then determine how much the generator efficiency value increases. In finding the efficiency value by making daily and monthly loading curves using generator output power, generator input power data, generator nameplate and generator power losses at 25%, 50%, 75%, and 100% loading. In this study, taking a sample that lasted for 1 month (31 days) of generator efficiency data for each loading and comparing the actual with the generator specifications, the difference for loading 25% experienced a decrease in efficiency of 0.35%, for loading 50% experienced an efficiency increase of 0.12%, for loading 75% increased efficiency of 0.25% and for loading 100% increased efficiency of 0.32%. In this study the generator has experienced reverse power so that the efficiency of the generator has decreased. The average efficiency in May 2022 was 96.21%, with an average load of 29.96 MW and an average input power of 31.14 MW. Referring to the manual book Block 2 PLTGU PT. CEPA Sengkang is known that the generator efficiency value is by design divided into 4 loadings. For loading 25% efficiency is 96.6%, for loading 50% efficiency is 98.45%, for loading 75% efficiency is 98.82%, and for loading 100% efficiency is 98.93% and so that the optimum efficiency of the generator occurs at a load of 54.2 MW (loading 100 %) with a value of 99.62%.

Abstract

In the current digital transformation era, network providers have long relied on WAN technology to support the business communications of their multi-local companies; however, in terms of infrastructure, cost, and even effectiveness, WAN technology is no longer sufficient to meet the needs and demands of telecommunications customers. In addition, given the magnitude of the company's need for internet network connections, technology is also needed to manage the use of traffic from rental links in the company so that it can optimize bandwidth usage from the link itself. Therefore one of the technological innovations to improve information processes is cloud-based digital innovation such as SD-WAN Traffic Steering technology. In this paper, the SD-WAN network design will be carried out on FortiGate series 50e devices by implementing traffic steering technology which can adjust a link's traffic flow according to the client's wishes. The results of the data obtained indicate that the utilization of ISP links owned by companies (Lintasarta and MNC) has been able to be used optimally, as evidenced by the use of bandwidth on each link successfully used according to the desired settings, where the settings provided have also been adjusted according to parameters of the type of each ISP service so that functionally the existing service link can be used optimally by the compan
