Abstract

DITSAMAPTA Polda Utara Sumatera is one of the Working Units of the North Sumatra Regional Police, based on Police Regulation Number 14 of 2018 DITSAMAPTA has a main role and task in terms of fostering and carrying out general police duties (regulation, guarding, escorting, patrolling, handling Tipiring, handling TPTK, security and rescue assistance), crowd control and demonstrations, animal assistance in carrying out tracking, deterrence, providing tactical assistance in carrying out investigative and investigative duties. From these various tasks, DITSAMAPTA has problems in collecting data and placing personnel to carry out their main daily tasks, so that things often occur such as multiple assignments to one personnel, several main tasks are not fulfilled due to errors in reporting the number of personnel in real terms, and other tasks related to the assignment or placement of personnel, this is because DITSAMAPTA in its personnel data collection is still manual, resulting in inaccurate information and confusion in deciding the policies of leaders in the field. Given these problems, a study was conducted to monitor the activities of DITSAMAPTA personnel which aims to provide convenience in finding information on any personnel on duty, standby, not entering the office such as: sick, permits, leave and so on. Monitoring of personnel activities is carried out using a website-based application. The website is a platform to make it easier to find information and facilitate communication. The application applies the UCD (User Centered Design) method where the system can provide more accurate and precise according to user needs.

Abstract

The building is an important part of the wedding ceremony. Especially if the event owner does not have sufficient land. So far, it's been difficult for the community to decide which wedding hall they want. Both in terms of location, building design, rental prices etc. The purpose of this research is to apply the Multi Attribute Utility Theory (MAUT) method to recommend building rental services. The criteria used to select a building are location, price, facilities, parking space capacity, and number of guests. The alternatives used are Adi Mulia Hotel Medan, Caffe Bel Mondo Medan, Andaliman Hall, Aceh Sepakat, Al-amjad Convention Hall, Wisma Mahina Center, Mutiara Suara Nafiti Convention Hall, Namaken Hall, Al-Maruf Multipurpose Building, and the Dharma Wanita Petisah Building. The results of applying the MAUT method show that the Al-Amjad Convention Hall is most recommended as the building that best fits the given criteria.

Abstract

Workshop activities in the field of education are urgently needed to provide the latest information in the learning process, especially for elementary schools in remote areas. To carry out these activities requires large funds and also resource persons who have expertise in their fields. Therefore, it is necessary to have financial assistance or funding from several people which are commonly called crowdfunding and also volunteers who can help elementary schools. So that workshops and educational activities regarding education can be carried out to support the learning and teaching process properly. To overcome this problem, a crowdfunding application was built that can manage financial assistance from the community and volunteer teaching staff, so that they can carry out educational activities or workshops for elementary schools in remote areas that need these activities. This research uses the Lean Startup method as application development because the method is easy to implement so that the resulting application is in accordance with the needs. Where there are three stages, namely building, measuring and studying so that it makes it easier to design applications that are tailored to the existing target market. The results of this research are this mobile-based crowdfunding application that can help fundraise and also volunteer teaching staff to be able to hold educational activities and workshops for elementary schools in remote areas.Keywords: Crowdfunding, Workshop, Lean Startup, Elementary School.

Abstract

This study aims to analyze research trends and knowledge structures in explainable artificial intelligence (XAI) for predictive modeling through a bibliometric review approach. Data were obtained from Scopus metadata in BIB format exported on June 30, 2026. The initial search strategy yielded 343 documents, which were then filtered based on article document type, English language, and journal source, resulting in 177 articles analyzed for the period 2015-2026. The analysis was conducted using a bibliometric approach through mapping publication productivity, journals and primary authors, influential documents, country contributions, keyword co-occurrence, trend topics, thematic maps, and thematic evolution. The results show that XAI research for predictive modeling experienced a strong acceleration after 2023, indicating a shift in focus from predictive models that are solely accuracy-oriented to models that are transparent, explainable, and accountable. The intellectual structure of this field is interdisciplinary, with contributions from computer science, education, health, energy, environment, geospatial, industry, materials, and engineering. The dominant themes center on machine learning, data mining, forecasting, interpretability, SHAP, LIME, and deep learning, while emerging themes focus on counterfactual explanation, causality-aware forecasting, physics-informed learning, transformers, and graph neural networks. This study identifies five key gaps: method, data, application, theory, and evaluation. The primary contribution of this research is to provide a systematic mapping of the developments, intellectual actors, dominant themes, emerging themes, and future research agendas of XAI to build more accurate, transparent, auditable, and accountable predictive modeling
