Abstract

The population growth and increasing economic activity in Samarinda City have led to a rising demand for temporary housing such as boarding houses. However, rental price determination is still largely based on the owner’s intuition rather than objective factors such as available facilities, room specifications, transportation accessibility, and proximity to public amenities. This study aims to develop a rental price prediction model for boarding houses using the Extreme Gradient Boosting (XGBoost) algorithm with a Knowledge Discovery in Database (KDD) approach. The research data were collected through a web scraping process from the Mamikos platform, yielding 231 initial records, which were then cleaned and filtered for outliers, resulting in 225 valid data points. Five main features derived from feature engineering were utilized in the model, namely Facility Score, Combined Specification Score, Nearest Place Score, Transportation Score, and Rental System Score. The evaluation results show that the XGBoost model achieved a Mean Absolute Error (MAE) of Rp348,822, a Root Mean Squared Error (RMSE) of Rp416,139, and a coefficient of determination (R²) of 0.612. These values indicate that the model can explain 61.2% of the variation in rental prices with reasonably good predictive performance. The feature importance analysis reveals that Facility Score and Combined Specification Score are the most influential factors affecting rental prices, while transportation and rental system factors contribute less significantly. This study is expected to serve as a reference for boarding house owners, tenants, and policymakers in determining more objective and competitive rental prices based on a data mining approach.

Abstract

Wicida Tvis one of the UKM (Student Activity Units) at STMIK Widya Cipta Dharma. The UKM has various social media and in this study the Wicida TvInstagram account was chosen, which aims to analyze the level of interaction with followers and other users on the content published on the Wicida Tv’s Instagram account. By using a mix method approach, with a focus on quantitative calculations for engagement rate results and qualitative methods are used to support the results of quantitative calculations. Data was collected based on Instagram content both photos, video viewers, reels, and posters uploaded in the last 1 year period (2025), in collecting engagement rate data not only using the number of likes, comments, shares, and reposts, but also can be taken by measuring how often people click on the link and bio in the post as well as the distribution of questionnaires which will later be processed using SPSS tools. The results of the analysis show that the engagement rate of the content on the Wicida TvInstagram account on average has an average engagement rate that can be said to be quite good. And while users are generally more interested in entertainment content than formal educational content, factors such as upload time and creativity have been shown to influence user engagement levels. This research provides insights for social media account managers in improving content strategies to achieve optimal follower engagement.

Abstract

Teacher Professional Education (PPG) for SMA / SMK in East Kalimantan Province is higher education after an undergraduate education program that prepares students to have jobs with special skills requirements to become teachers. The problems in registration that occur at the East Kalimantan Provincial Education and Culture Office are: The calculation of the test data is still calculated manually, so it is necessary to build a Decision Support System for Determination of Participants in the Professional Teacher Education (PPG) for SMA / SMK in East Kalimantan Province using the Web-based SMART Method. The data collection method uses the observation method and the system development method uses the method of the decision support system, namely the intelligence, design, choice, and implementation stages. Because this method has clear, practical stages. Then the system testing is White Box and Beta Testing. With the existence of a Decision Support System for Determining Who Participates in Professional Education for Teachers (PPG) for SMA / SMK in East Kalimantan Province with the Web-based SMART Method, it can handle the calculation process when the test has been implemented. In the test results it can be concluded that the results of testing the questionnaire questions to ten (10) respondents can be concluded that more than 78.2% of respondents answered that the Determination Decision Support System Participating in Teacher Professional Education (PPG) at the High School / Vocational School Level of East Kalimantan Province with the SMART Method Web-based meets the criteria for a good website or web application.
