Abstract

The development of information and communication technology is currently increased, especially related to social media. Nowadays, many people get information through social media, especially Twitter, because of its easy access and it doesn't cost much. However, it has a negative impact in the form of spreading fake news or hoaxes that are difficult to detect. In this research, the authors developed a hoax news detection model using the Convolutional Neural Network and the TF-IDF weighting method. Feature selection is performed using Information Gain with various features, such as unigram, bigram, trigram and a combination of the three. Testing is done with 3 scenarios, classification, classification by weighting, classification by weighting and feature selection. The parameter used in the information gain feature selection is the threshold 0.8. The results showed that the classification by weighting and feature selection produced the highest accuracy that is equal to 95.56% on the unigram + bigram features with a comparison of training data and test data 50:50.

Abstract

PDAM Tirta Patriot has implemented information systems for its business process but still has deficiencies, including some business processes that do not have documented guidelines and procedures. Furthermore, the human resources in PDAM Tirta Patriot are insufficient for improving IT governance due to the lack of reliable personnel in the IT unit. Given the importance of IT for PDAM, an audit is needed to evaluate the capability of the IT unit in managing IT. COBIT 5 provides a goals cascade to align the company with its business goals. However, the goals cascade does not provide priority to IT-related goals. Therefore, for prioritizing IT-related goals, this research uses Analytical Hierarchy Process (AHP). From the AHP result, the selected domains are APO01, MEA01, and APO07. This research aims to determine the current capability level and analyze the gap between it and the chosen target capability level, precisely level 2. The current capability level of PDAM Tirta Patriot from domain APO01 is 1, MEA01 is 0, and APO07 is 0, which means none of those have reached the target capability level. Recommendations are given based on the unfulfilled work product for domains that do not reach the target capability level.

Abstract

Project monitoring is an important aspect of project management that can affect project success. In interviews with PT Gerbang Sinergi Prima (GSP) stakeholders, project monitoring is still uses manual ways to make the process more efficient and accurate. As a result, it causes delays, cost overruns, or even project failure. Hence, this research aims to develop a mobile application for project monitoring at GSP. The development of the GSP project monitoring mobile application uses a Scrum pattern based on Agile methodology and testing with black-box and user accepted testing (UAT). The Scrum pattern could help the development team produce effective and efficient mobile application development according to changing project needs. The results showed that project monitoring using mobile applications has a positive effect on the effectiveness of project monitoring. Black box testing results showed 100% success on nine modules, ensuring all features functioned adequately. UAT showed 74% positive statements that met user needs and 46% negative statements indicating the application was quite convenient. Furthermore, the mobile project monitoring application is consistently and continuously used for all ongoing projects in the company. We suggested that it is necessary to conduct training for new users of the mobile project monitoring application.

Abstract

Vaccine hesitancy remains a critical public health issue in urban Indonesia, where healthcare access coexists with growing skepticism toward immunization. This study assessed the impact of a structured health education program on improving vaccine literacy and reducing parental hesitancy toward childhood vaccination. Using a quasi-experimental pre–post design, 240 parents from two urban health centers in Jakarta and Surabaya were assigned to intervention and control groups. The intervention included seminars, printed materials, and moderated WhatsApp discussions. Data on vaccine literacy, vaccination intent, institutional trust, and misinformation exposure were collected through validated instruments and analyzed using paired t-tests and multiple regression. Results showed a 33.1% improvement in vaccine literacy and a 28% increase in vaccination intent among the intervention group. Institutional trust and participation in the education program emerged as key predictors of reduced hesitancy, whereas misinformation exposure had a strong negative influence. In areas with low trust in healthcare institutions and high misinformation exposure—where over 40% of parents reported encountering false vaccine narratives—the intervention’s impact was weaker. The findings highlight that effective vaccine education must go beyond knowledge dissemination by integrating cultural narratives, emotional engagement, and community-based trust-building. While structured education enhances literacy and intent, sustainable behavioral change requires a multidimensional strategy combining education, empathy, and institutional credibility to strengthen urban immunization efforts.

Abstract

BIM (Building Information Modeling) is a 3D model simulation that connects planning, design, construction, and operational information to increase construction effectiveness and efficiency. However, BIM adoption in Indonesia is relatively slow. Therefore, the identification of BIM implementation conditions is carried out to determine the direction of its development. Optimal BIM implementation is based on two factors: BIM functions maturity and implementation of supporting facilities. Based on research, most BIM is used in the project phases: Construction, Design, and Planning using the applications: REVIT, Navisworks, and BIM 360. The main benefits of using BIM are: Collaboration Team Building, Communication, and Clash Detection. Rules (Preparation, Regulations, and Contracts) are the main factors inhibiting BIM Implementation. Regulations need to be drawn up regarding applications that are often used by construction implementers. The development for BIM implementation is formulated into 8 Proposals which are divided into 3 stages: Short, Medium, and Long. BIM implementation has the potential to develop traditional DBB (Design-Bid-Build) Project Delivery into DB (Design-Build). There are as many BIM implementations with DBB type as DB, showing that the use of BIM can facilitate the use of DB. The involvement of a BIM Engineer is essential in implementing projects with BIM. Keywords: BIM (Building Information Modeling), BIM application, BIM engineer, BIM implementation roadmap, conditions for implementing BIM in other countries, identification of BIM implementation conditions, implementation barriers, maturity of BIM function utilization, project delivery, supporting facilities
