Abstract

A room that should be comfortable for humans can create a sense of absence and appear diseases and other health problems. These rooms can be from boarding rooms, hotels, office rooms, even hospital rooms. Room occupancy prediction is expected to help humans in choosing the right room. Occupancy prediction has been evaluted with various statistical classification models such as Linier Discriminat Analysis LDA, Classification And Regresion Trees (CART), and Random Forest (RF). This study proposed learning approach to classification of room occupancy with multi layer perceptron (MLP). The result shows that a proper MLP tuning paramaters was able estimate the occupancy with 88.2% of accuracy

Abstract

Poor urban air quality is a major public health concern, especially in highly urbanized areas. This study aims to predict health risks associated with air pollution using machine learning techniques based on environmental variables. The dataset used, Urban Air Quality and Health Impact, contains 1,000 rows and 46 columns, including temperature, humidity, wind speed, dew point, ultraviolet (UV) index, and health risk scores from major U.S. cities. As an improvement over previous studies using linear regression and Random Forest (R-squared 0.89; Mean Squared Error/MSE 0.65), this research implements an optimized Extreme Gradient Boosting (XGBoost) model. The model was fine-tuned using Randomized Search on key hyperparameters and evaluated with an 80:20 data split. It achieved an R-squared of 0.9692 and MSE of 0.0122. Dew point and wind speed were identified as the most influential features. Although synthetic, the dataset reflects environmental patterns similar to Indonesian urban areas. This study does not adopt a text mining framework but instead uses a supervised regression approach based on environmental features. Its main novelty lies in the first application of an optimized XGBoost model using complex variables such as feels-like temperature to estimate urban health risk. Limitations include the absence of real-world validation with Indonesian data and the lack of analysis on interactions between variables

Abstract

Non-formal educational institutions such as tutoring centers play a vital role in enhancing the quality of education within communities. However, many of these institutions face challenges in management governance, particularly in establishing standardized operational procedures and financial accountability systems. This community engagement program aimed to strengthen the management capacity of the Eka Learning Center (ELC) by developing Standard Operating Procedures (SOPs) and an accountable, transparent bookkeeping system using Microsoft Excel. The method adopted was a participatory approach, consisting of socialization sessions, technical training, simulation practices, and intensive mentoring for ELC administrators. The outcomes demonstrated a significant improvement in the partners’ understanding and skills in preparing applicable SOP documents and recording financial transactions systematically through customized Excel templates. Furthermore, the partners showed enhanced capacity in generating basic financial reports that are internally and externally accountable. This program contributed positively to increasing operational efficiency and institutional transparency. The success of this activity is expected to serve as a model for similar educational institutions and support the achievement of Sustainable Development Goals (SDGs), particularly in the areas of quality education and good institutional governance.
