Abstract

This paper presents a new method for fault classification and detection in transmission lines using the Chimp Optimization Algorithm (ChOA) integrated with Support Vector Machine (SVM). The adding complexity of modern power schemes demands more accurate and efficient methods for identifying and classifying faults to ensure system reliability and minimize downtime. The proposed method leverages the strengths of ChOA, an optimization procedure motivated by the social actions of chimpanzees, to optimize the parameters of the SVM, enhancing its ability to classify different types of faults accurately. By combining ChOA with SVM, the method not only improves fault classification accuracy but also reduces computational time, making it suitable for real-time applications. Extensive simulations were conducted using various fault scenarios and configurations to justify the execution of the ChOA-SVM model. The outcomes demonstrate that the suggested approach outperforms traditional fault detection procedures in precision, speed, and adaptability to different transmission line conditions. This study aids to the field of power system protection by giving a robust and efficient solution for fault classification and detection, with potential applications in enhancing the resilience and reliability of transmission networks..

Abstract

SMPN 1 Sedati or commonly called SPENSASED is a junior high school located in Sedati, Sidoarjo Regency, East Java Province, Indonesia. The school has a long history of creating quality education programs for its students. Over time, SMPN 1 Sedati has become one of the fastest growing educational units and has earned the nickname Movers School. The curriculum used at SMPN 1 Sedati is an independent curriculum, which focuses on developing students' interests and talents. Not only the academic program is improved, but the extracurricular program is also very concerned. But on the other hand, the development of technology at SMPN 1 Sedati tends not to be as fast as the educational program. As an example of the topic I used, namely about Committee Financial Governance, the absence of a program that can support the performance of the staff in charge makes everything related to committee finances must be done manually and cannot be monitored in real time. In the design, the author explores further information about the main needs of the treasurer and financial staff at SMPN 1 Sedati as the main support in the system development process. The author aims to assist related parties in managing committee finances in order to create transparency and actual information.

Abstract

Purwoyoso Health Center, located at Jl. Siliwangi No. 572, is a non-inpatient health facility that provides medical record and laboratory examination services. Currently, the patient data recording and search system is still done manually, resulting in difficulties in finding patient data who do not bring a medical book (KIB), as well as increasing the risk of data duplication and loss. To overcome this problem, the development of a web-based medical record service application is proposed as an effective solution, by following the waterfall method and using tools such as DFD, flowchart, and MySQL database. Application testing will be carried out using the black box method to ensure its functionality. The advantages of this application include increased efficiency of service time, ease of searching for patient data, and better data storage security. With the implementation of this application, it is hoped that Purwoyoso Health Center can improve the quality of medical record services and provide faster and more accurate access to patient information, as well as support better decision-making in health services.

Abstract

Agriculture is one of the mainstays of the country's economy, especially the horticulture sub-sector such as fruits and vegetables. Tomato plants are one of the leading commodities. However, the failure of tomato cultivation due to the many types of diseases that exist is still an obstacle and interferes with plant growth, reduces yields, and even causes tomato plant death. This study aims to detect tomato leaf diseases by comparing the performance of the two YOLOv5 and YOLOv8 models. The purpose of comparing models is to determine the level of accuracy and to conclude which version of YOLO provides a better level of accuracy in the hope of helping to determine which method is most appropriate and appropriate to needs. The results showed that both YOLOv5m and YOLOv8m models performed very well in detection. Both models showed high precision, recall, and mAP values. YOLOv8m is better able to detect all objects in the image where the precision value is superior to YOLOv5m. YOLOv8m is superior in precision with a value of 0.95%, a difference of 0.02% with YOLOv5m and mAP50:95 which is 0.92%, a difference of 0.02% with YOLOv5m which means that YOLOv8m is better at identifying objects very precisely and objects of various sizes, but YOLOv8m requires a slightly longer training time than YOLOv5m. YOLOv8m is better able to detect all objects in the image where the precision value is 0.02% superior to YOLOv5m
