Abstract

The need for increasingly advanced technology covers almost all existing aspects and one of them is within the company, including the personnel department. There are many processes within the staffing department such as employee permits, leave applications that are still done manually and have to interact face-to-face with superiors and HRD and also apply for permits such as overtime, official permits. This activity is still carried out manually and is not effective because too many related parties are involved to obtain permits. Therefore, a system is urgently needed to simplify the process and make the process effective. System development using waterfall which includes system survey, system analysis, system design, system creation, system implementation, and system maintenance which is expected to make it easier for employees to apply for leave, apply for overtime and apply for official permits. This application is based on a website and the creation of this application program uses the waterfall method and uses programming languages ​​such as PHP, javascript and CSS.

Abstract

Provision, management and distribution of water on agricultural land is one of the important factors that affect the quantity and quality of agricultural products. An irrigation canal technology is needed that is able to flow through all agricultural land according to the water needs of each land. Smart irrigation systems can be a solution to this problem. The smart irrigation technology that was previously developed has several limitations such as the length of time data transmission takes to reach the client, sensor devices in the field must take turns sending data and receiving data resulting in data not being sent or not being read properly, besides that the system that has been developed previously depends on to one factor, namely the water level to determine the degree of openness of the floodgates. In this research a fast sensor to cloud communication system is designed using websocket technology. This system is also designed to send and receive data simultaneously using full duplect communication technology. As well as using artificial intelligence with the decision tree algorithm to regulate the openness of the floodgates based on the water requirement for the rice fields, the water level in the irrigation canals and the speed of the water flow. This research produced a prototype of an intelligent irrigation system that can send data to clients with an average time of 417ms, the system is also able to handle 500 clients that are connected directly to the server. The system can also send and receive data simultaneously with a difference in time when data is received at the sensor node or at the central node which can reach 0ms. This prototype also succeeded in making an artificial intelligence system that is accurate, fast and real-life. This artificial intelligence can handle 500 requests simultaneously with an execution time of 544ms.

Abstract

Noise contamination in electrocardiogram (ECG) monitoring systems can lead to errors in analysis and diagnosis, resulting in a high false alarm rate (FAR). Various studies have been conducted to reduce or eliminate noise in ECG signals. However, some noise characteristics overlap with the frequency range of ECG signals, which occur randomly and are transient. This results in shape alteration and amplitude reduction in P and R waves. The author proposed a framework for eliminating noise in ECG signals using the stationary wavelet transform method and interval-dependent thresholds (IDT) based on the change point detection method to address these challenges. The proposed framework decomposes the input electrocardiogram (ECG) signal at a specific level using the Stationary Wavelet Transform method, resulting in detail and approximation coefficients. Interval detection focuses on the initial detailed coefficient, d1, chosen due to its significant content of noise coefficients, especially high-frequency noise. Subsequently, threshold values are computed for each interval. Hard and soft thresholding processes are then applied individually to each interval. Finally, reconstruction occurs using the inverse stationary wavelet transform method on the threshold coefficient outcomes. Two measurement matrices, root mean square error (RMSE) and percentage root mean squared difference (PRD), were used to measure the performance of the proposed framework. In addition, the proposed framework was compared to stationary wavelet transform (SWT) and discrete wavelet transform (DWT). The test results showed that the proposed method outperforms DWT and SWT. The proposed framework obtained an average increase in RMSE scores of 18% and 45% compared to the SWT and DWT methods, respectively, and PRD values of 17% and 37% compared to the SWT and DWT methods, respectively. So, using IDT in the stationary wavelet transform method can improve the denoising performance. With the development of this new framework for denoising ECG signals, we hope it can become an alternative method for other researchers to utilize in denoising ECG signals.

Abstract

This study aims to experimentally analyze the effect of coolant temperature on the performance of a Thermoelectric Generator (TEG) combined with a finned aluminum heatsink. The TEG operates based on the Seebeck effect, where a temperature difference between the hot and cold sides generates electrical energy. The experiment employed six SP-1848 TEG modules arranged in series and mounted on a heatsink partially immersed in static water as a cooling fluid. Measurements were taken every 300 seconds for a total of 3600 seconds, monitoring parameters such as hot side temperature (Th), coolant temperature (Tc), voltage, and current, as well as calculated power and efficiency. The results showed that the increasing exposure time to solar heat gradually raised Th, while Tc increased more slowly. The resulting temperature difference (ΔT) directly contributed to an increase in electrical power output of more than 0.005 W, and TEG efficiency exceeding 14%. This study highlights the importance of thermal management through heatsinks and coolant fluids in optimizing TEG performance, particularly in small-scale renewable energy applications.
