Abstract

The rapid advancement of Information Technology has become a crucial element in enhancing business decision-making efficiency. Putra Mart, a prominent wholesaler in Bintuhan City, faces significant operational challenges due to its reliance on manual inventory recording and supply management systems. These manual processes often lead to data inaccuracies, stock imbalances, and difficulties in identifying market demand patterns. This research aims to address these issues by implementing data mining techniques using the K-Means Clustering algorithm to categorize inventory data into strategic groups based on stock levels and supply frequency.The system development follows the structured Waterfall model, which includes requirements analysis, system design using Data Flow Diagrams (DFD), coding with Visual Basic .Net 2010, and database management using SQL Server 2008. The clustering process utilizes the Euclidean Distance formula to measure the proximity between data points and centroids, effectively partitioning the items into two main clusters: "Fast Moving" and "Slow Moving" goods.The results of the analysis on 2020 transaction data successfully identified a clear distribution of products, with Cluster 1 accounting for 40% of the tested items. System testing through the Blackbox method confirmed that all functional features operate correctly, while a user satisfaction survey yielded a score of 84%, categorized as "Good." This study concludes that the implementation of the K-Means algorithm provides a reliable, data-driven solution for Putra Mart to optimize its inventory management, minimize deadstock, and improve overall service quality for its partner stores

Abstract

The accumulation of waste at Pasar Minggu Market in Bengkulu City has become an environmental issue that affects cleanliness, public health, and the comfort of trading activities in the market area. This condition is not only caused by the limited availability of waste management facilities but is also related to the lack of effective communication between the government as the environmental management authority and the community and traders as users of public space. This study aims to analyze the crisis communication carried out by the Environmental Agency of Bengkulu City in handling the waste problem at Pasar Minggu Market. The research employed a qualitative approach with a descriptive method to provide an in-depth description of the communication processes involved in managing this environmental crisis. Data were collected through in-depth interviews, field observations, and documentation involving informants from the Environmental Agency, market traders, and local community members around Pasar Minggu Market. The findings indicate that the government’s communication in addressing the waste crisis has not been effective because it tends to use a one-way communication pattern and does not actively involve the community in waste management efforts. In addition, limited waste transportation facilities, inadequate waste disposal infrastructure, and low public awareness of environmental cleanliness further worsen the situation. Therefore, strengthening a more participatory communication strategy is necessary through increased direct socialization, transparent information dissemination, and active involvement of both the community and traders in maintaining the cleanliness of the market environment in a sustainable manner.

Abstract

This study examines the role of public relations of the Seluma Regency Regional House of Representatives in increasing public trust through digital communication on the institution’s Instagram account. The development of digital media has transformed communication patterns between public institutions and society, making information transparency, responsiveness, communication consistency, and public involvement important factors in building public trust in government institutions. The purpose of this research is to analyze how the public relations unit of the Seluma Regency Regional House of Representatives manages digital communication through Instagram in order to enhance public trust. This research uses a qualitative approach with a descriptive method. Data were collected through interviews with public relations officers and social media administrators, observation of digital communication activities on the institution’s Instagram account, and supporting documentation related to public communication activities. The findings show that the Instagram account of the Seluma Regency Regional House of Representatives functions as a medium for basic information transparency by publishing institutional activities such as meetings, working visits, and other official agendas. However, the transparency presented is still dominated by visual documentation and does not provide sufficient substantive information regarding the results of activities or policy decisions. Responsiveness to public questions and comments remains limited, causing digital communication to operate mostly in a one way pattern. Although posting activities appear relatively consistent, the accountability of information is not yet fully developed because the content emphasizes activity documentation rather than the explanation of institutional performance outcomes. In addition, public involvement remains low because interactions from citizens are rarely followed by visible responses or follow up from the institutio.

Abstract

This research aims to implementation the symetric probability algorithm in building an expert system to diagnose diseases due by nutritional disorders. Disturbances in nutritional balance can cause a person's performance in activities to be not optimal and can even cause diseases that will interfere with daily routines. The lack of knowledge and concern for nutritional balance in the body is the cause of the emergence of health problems, in addition to the difficulty of access to consult a doctor also causes people to be less concerned about nutritional balance disorders. To overcome these problems, it is necessary to build an expert system to help someone diagnose diseases due to nutritional disorders and solutions that can be done online so that it is expected to facilitate users. The implementation of symetric probability used in this expert system can provide diagnoses of nutritional disorders expressed as a percentage to measure the certainty value of a hypothesis against a fact of disease due to nutritional disorders experienced by adults. This expert system was built using PHP programming language and MySQL database. This expert system can be used as a tool that makes it easier for people to diagnose early symptoms of diseases due to nutritional disorders because it can be accessed online.

Abstract

KUA Ulu Musi Sub-district is one of KUA offices in Empat Lawang Regency that plays an important role in recording and facilitating marriage processes, including issuing permits, recording, and issuing related documents. Until now, data processing at KUA Ulu Musi has been done manually through data recording books, and the number of marriages is written on a board provided as information. Given that the number of marriages fluctuates annually from 2014 to 2023, KUA sometimes faces difficulties in ensuring the availability of documents, managing wedding queues, and preparing the necessary facilities. The implementation of data mining in predicting the number of marriages using the least squares method at KUA Ulu Musi can provide information regarding the predicted number of marriages for the following year, enabling KUA to prepare sufficient administrative staff and personnel to serve prospective couples optimally and avoid case backlogs during certain periods. Based on test data with two data conditions—odd numbers (2014–2022) and even numbers (2014–2023) the predicted number of marriages for 2023 was 166, and for 2024, it was 168. From the accuracy level testing, the accuracy level calculation yielded a MAPE error percentage of 18.43%, indicating good accuracy. This shows that the least squares method is sufficiently reliable in predicting the number of marriages at KUA Ulu Musi.
