Cows are one of the most widely cultivated livestock animals in Indonesia, especially in the Asahan district alone, according to data from Asahan in Figures for 2022, in Asahan District in 2021 there will be 146,511 heads spread across 25 sub-districts. Cow disease is no longer a strange thing for livestock breeders. The symptoms that appear in cattle must be known as soon as possible before the disease appears with a ferocity that will cause the risk of death in cattle. death in Mr Poniman's cattle. Due to tympanic disease (bloating), at the time of this incident there were still few cows and people did not know how to treat it, so the cows eventually died with enlarged stomachs. With the availability of technology, the author built an expert system for diagnosing cattle diseases that can diagnose cattle diseases and provide treatment suggestions, both medical and natural, using the forward chaining method and certainty factor. Forward chaining first selects facts that are appropriate to the problem that is occurring, and the certainty factor will determine the result of the percentage of confidence of an expert. This system was built based on a website.

Sales forecasting is an important element in inventory management to ensure product availability in accordance with market demand. One method that can be used for forecasting is the Single Moving Average (SMA), which works by calculating the average sales in a certain period to identify future sales trends. This research aims to implement the SMA method in forecasting sales of motorbike spare parts in order to increase stock management efficiency and reduce the risk of excess or shortage of inventory. This research method involves collecting historical data on sales of motorbike spare parts in a certain period, which is then analyzed using the SMA method with various average period lengths to determine the best accuracy. The research results show that the SMA method can provide fairly accurate estimates of future demand patterns. With better forecasting, stores or distributors can optimize procurement strategies and reduce unnecessary carrying costs. Apart from that, implementing this method also contributes to increasing customer satisfaction because product availability can be more guaranteed. The conclusion of this research shows that the Single Moving Average method is a simple but effective forecasting technique in motorcycle spare parts inventory management. Implementation of this method can help business people make more appropriate decisions in stock planning and marketing strategies.

This research aims to develop an expert system in diagnosing diseases in potato plants using the Case Based Reasoning (CBR) method approach combined with the K-Nearest Neighbor (K-NN) algorithm. The system is designed to help farmers identify the type of disease based on the symptoms that appear, as well as provide relevant solutions to increase crop productivity. In previous research, the CBR method showed a limited accuracy rate of 74% because it only relied on one algorithm. Through the application of two methods in data analysis, namely CBR and K-NN, this study succeeded in increasing the diagnosis accuracy to be higher than the previous approach of 80%. The system is implemented in the form of a web-based application that is easily accessible by farmers. The results show that the integration of these two methods provides more optimal, effective, and accurate results in detecting potato plant diseases based on symptom data. The findings are expected to contribute significantly to the development of agricultural technology, especially in improving the harvest success of potato farmers in Indonesia.

The challenge of accurately identifying instances of crime and traffic issues has rendered the precise localization thereof difficult, thereby impeding the populace's access to information concerning areas of high risk and safety. Employing a Geographic Information System (GIS)-based mapping system utilizing the K-means clustering method, spatial data pertaining to crime and traffic concerns are grouped. The primary objective is to aid in the identification of high-risk areas concerning crime and traffic matters. The methodology employed in this study revolves around the application of the K-means clustering method to categorize spatial data relevant to crime and traffic issues. K-means clustering represents a non-hierarchical cluster analysis technique designed to partition data into multiple groups based on spatial similarities. Research findings elucidate that through the utilization of the K-means clustering method, three distinct sets of clusters predicated upon the intensity of crime and traffic issues emerge. Consequently, from these clustering outcomes, districts and specific locales falling within each cluster, denoted as moderately vulnerable (C1), vulnerable (C2), and highly vulnerable (C3), can be delineated. This system is poised to furnish recommendations to pertinent authorities for addressing areas exhibiting heightened intensity levels while concurrently facilitating the generation of reports and dissemination of information to the public via a dedicated website pertaining to areas at elevated risk of crime and traffic issues.

Scheduling in education has been a common issue faced, particularly concerning the mismatch between class hours and teacher availability. Addressing this necessitated careful precision and a significant amount of time for subject scheduling. Genetic algorithms emerged as a suitable choice for managing school subject scheduling due to their capability to address multi-criteria and multi-objective problems inspired by biological evolution. The concept of genetic algorithms could be effectively applied in the context of schedule arrangement within educational institutions. This study employed a quantitative methodology and implemented the Rapid Application Development (RAD) system development method. The utilization of genetic algorithms in subject scheduling, as demonstrated in this research, was deemed beneficial for correctional institutions previously engaged in manual scheduling processes. The outcomes indicated the success of the genetic algorithm approach in resolving school scheduling issues by seeking optimal scheduling combinations, as evidenced by achieving maximum fitness values and minimal errors (in this case, an error value of 0), indicating the absence of class schedule conflicts.

Perkembangan teknologi informasi yang pesat telah merambah hampir semua aspek kehidupan, termasuk di bidang kelautan dan perikanan. Dinas Kelautan dan Perikanan Provinsi Sumatera Utara menggunakan sistem informasi e-log book untuk mengumpulkan data secara akurat. Institusi ini bertanggung jawab memantau kegiatan perikanan, termasuk data penangkapan ikan dan lokasi operasi. Penggunaan log book fisik oleh nelayan untuk mencatat hasil tangkapan sering kali memakan waktu dan menghasilkan data yang kurang terstruktur. Aplikasi e-log book dikembangkan menggunakan metode Progressive Web App (PWA) dan GPS untuk melacak lokasi nelayan dan kapal, memungkinkan pelaporan dengan informasi lokasi yang akurat. Sistem ini mencatat dan mengunggah data penangkapan ikan, serta menyimpan data secara offline. Dengan demikian, nelayan dapat mengisi log book di lokasi penangkapan menggunakan perangkat seluler dan merekam lokasi penangkapan secara akurat, yang membantu dalam pemantauan dan pelaporan yang lebih akurat. Sistem e-log book penangkapan ikan ini mempermudah pengumpulan data yang akurat serta pencatatan hasil tangkapan ikan dan pengirimannya ke pihak berwenang oleh petugas. Keakuratan data penangkapan ikan merupakan faktor krusial dalam mendukung pengelolaan sumber daya ikan, dan penerapan teknologi e-log book adalah solusi efektif untuk meningkatkan kecepatan dan akurasi data tersebut. Analisis terhadap kesenjangan penerapan teknologi e-log book di Indonesia menunjukkan bahwa e-log book yang dikembangkan sudah memadai dari segi perangkat keras, perangkat lunak,komunikasi data (satelit dan GSM/GPRS), dan sistem integrator.

World University Ranking is a system tool that functions to measure and assess all the best universities around the world (World Class University) which aims to advance all Universities through websites owned by each University. There are several problems in choosing a college. The selection of campuses or State Universities (PTN) is still often a problem or obstacle for every prospective student and parent to choose further education for the future of their children, especially as we often know that there are many universities in Indonesia. Indonesia ranges from state universities to private universities. One of the efforts in the selection recommendations made to facilitate this is to conduct an assessment of the best PTN. In this study, the Simple AdditiveWeighting (SAW) method was applied to the best college recommendation system. The criteria used are Tuition Fees, Academic Reputation, Employer Reputation, Teaching, Research, and Citation. After the criteria are determined, the next process is theranking process of the existing alternatives. The results of each method can provide recommendations for students or parents in choosing a college.
