Abstract

This research aims to evaluate the effectiveness of the PINTAR application, a Massive Open Online Course (MOOC) platform designed to support the training of State Civil Apparatus (ASN) within the West Sumatra Ministry of Religion. Using the ITIL V4 framework, this research assesses service quality, user satisfaction levels, and identifies areas that require improvement to ensure applications can provide optimal benefits. Evaluation is carried out through direct observation of application use, in-depth interviews with stakeholders, and distributing questionnaires to users. The research results show that the PINTAR application has met most of the service quality standards, especially in terms of accessibility, relevance of training materials and interactive features offered. However, there are several weaknesses that need to be corrected, such as limited transparency in managing user data, a lack of regular service evaluations, and the responsiveness of technical support which is still not optimal. Users highly appreciate the time flexibility, ease of navigation, and interactive features such as learning simulations and live sessions with expert instructors. On the other hand, the survey also revealed the need to strengthen technological infrastructure and increase the competence of technical support teams to handle user complaints more effectively. By applying ITIL V4 principles, this research offers strategic recommendations for further development of the PINTAR application. Recommended improvement steps include increasing governance transparency, additional training for technical teams, development of more sophisticated reporting features, and regular evaluation of training materials. In conclusion, although the PINTAR application has made a significant contribution in supporting ASN training, continuous improvement efforts are needed to ensure this application can continue to be relevant and provide maximum added value for users.

Abstract

The rapid development of Information and Communication Technology (ICT) has significantly impacted various aspects of human life, including governance. The City of Jambi, with an area of 205.58 km², manages approximately 7,147 Civil Servants (ASN) and 3,543 Contract Employees across various agencies. Human resource services in the city are managed by the Regional Civil Service and Human Resource Development Agency of Jambi City. Despite having a human resource management system in place, the current data collection process is still done manually using Microsoft Excel, which hampers data processing efficiency, causes frequent data duplication, and complicates reporting. To address these issues, this study aims to design a web-based Contract Employee Information System, which is expected to improve data accuracy and facilitate the management of employee information, both for ASN and Non-ASN employees. This system is anticipated to enhance the efficiency of data collection, storage, and reporting, while also supporting faster and more accurate decision-making in Jambi City Government

Abstract

Oral and dental health is an integral part of general health, yet high treatment costs and limited availability of dentists, especially in non-urban areas, often lead the public to delay examinations until complaints worsen. This research aims to develop a web-based expert system capable of providing early indications of oral and dental diseases quickly, accurately, and accessibly through a self-screening mechanism. This web application provides an expert system developed using Python (Flask) and designed with login/logout features for data security, as well as storing user information and diagnosis results in a database. The system utilizes the Forward Chaining method as the primary inference engine to process user-inputted symptoms, and integrates Certainty Factor to calculate and determine the confidence level of the diagnosis results. Testing has demonstrated ease of use, where users only need to answer symptom questions with "yes" or "no" to obtain a disease diagnosis and relevant treatment suggestions. Performance analysis based on trials with 40 simulated data shows the system achieved an accuracy rate of 85%, making it a reliable tool for initial screening.

Abstract

Artificial intelligence is the computer science sector which facilitates computers in performing tasks traditionally performed by humans. One of the interesting applications of ai is a system of experts, designed to mimic an expert's thinking and knowledge. In this study, a web-based expert system was developed to diagnose stunted potential in children of an early age by employing advanced methodologies of chaining. The purpose of this system is to increase public awareness and help parents recognize early stunting signs, thus enabling timely intervention. The system is developed with a cascading approach to ensure that each stage of development is implemented by a planned approach. Test results show that the system has a high diagnostic accuracy level, so it can be relied upon as an aid in a stunted risk assessment.
