Abstract

Increasing air pollution in DKI Jakarta has become an increasingly pressing environmental issue, which has a direct impact on public health and environmental sustainability. Therefore, it is very important to have a system that manages data-based air pollution levels. The purpose of this research is to classify air quality in DKI Jakarta through Air Pollutant Standard Index (ISPU) data. This data consists of parameters such as dust particles (PM10, PM2.5), sulfur dioxide (SO2), carbon monoxide (CO), surface ozone (O3), and nitrogen dioxide (NO2), as well as two classification algorithms used, namely C4.5 and Naïve Bayes. This research also seeks to compare the effectiveness of the two algorithms based on ISPU data collected in 15 Jakarta areas. The approach used in this research is to divide the data using three ratio scenarios, namely 70% : 30%, 80% : 20%, and 90%: 10%. In addition, performance assessment is carried out using accuracy, precision, recall and f1 score metrics. The experimental results showed better performance of C4.5, with an average accuracy of 95%, precision of 99%, recall of 94% and f1-score of 97%. In contrast, Naïve Bayes recorded an average accuracy of 81%, precision of 93%, recall of 73% and f1-score of 82%. These findings corroborate the validity of the C4. 5 algorithm is more effective in air quality classification based on ISPU, thus making it a reliable resource for air quality monitoring and management in DKI Jakarta, as well as supporting decision-making in air pollution control policies.

Abstract

This study analyzes the interrelationships between weather parameters, including average temperature (Tavg), relative humidity (RH_avg), rainfall (RR), and average wind speed (ff_avg) in North Jakarta and Central Jakarta, and compares the performance of Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) models in predicting these parameters. Data was collected from Tanjung Priok Maritime Meteorological Station in North Jakarta and Kemayoran Meteorological Station in Central Jakarta from December 2021 to December 2024. The results show that GRU performs better in North Jakarta, with RMSE of 9,02, MSE of 81,28, and MAE of 4,21 at 75 epochs, while LSTM yields RMSE of 10,02, MSE of 100,34, and MAE of 4,62 at 50 epochs. Conversely, LSTM outperforms GRU in Central Jakarta, with RMSE of 8,96, MSE of 80,22, and MAE of 4,65 at 100 epochs, while GRU produces RMSE of 9,53, MSE of 90,78, and MAE of 4,85 at 75 epochs. GRU is more effective in capturing extreme fluctuations, while LSTM excels in predicting interrelationships between parameters. This study provides insights into selecting the appropriate weather prediction model based on the priority of prediction accuracy or the ability to capture extreme fluctuations

Abstract

e-Puskesmas is an information system based on data and communication innovation in giving wellbeing administrations which is essential for the benefit of both patients and health care providers. However, the use of e-Puskesmas is still a challenge because some Puskesmas officers have difficulty in using e-Puskesmas. E-Puskesmas was introduced in 2016 and began to be used in Bekasi City Puskesmas in 2019. This study aimed to determine the intensity of e-Puskesmas use as reviewed from sociodemographic and user perception perspectives using the Technology Acceptance Model (TAM) concept. This study was a quantitative research with a cross-sectional design. The sampling method used was multistage random sampling, with a sample consisting of 214 health center officers from five health centers. The research instrument used was a Google Forms questionnaire. The data obtained were statistically tested using the chi-square test. The results showed that sociodemographic factors had a significant relationship with the intensity of e-Puskesmas use. In addition, there was a significant relationship between the perceived usefulness variable (0.018), perceived ease of use (0.014), and intensity of e-Puskesmas use.

Abstract

Based on (Law of the Republic of Indonesia No. 43 of 2007 concerning Libraries) it is stipulated that libraries are administrative institutions such as written, printed or recorded works that are professional and standardized systems that meet the needs of education, research, information, and preservation, and recreation of visitors (Chapter I Paragraph 1) In the law called "Chapter V Article 14 Paragraph 3" then regulated by all libraries provide good services to advance information and communication technology. Thus the authors try to formulate the problem, namely how to create a computerized school book lending program and use a web-based program using codeigniter at SD Muhammadiyah 2 Waru in order to process data faster and with a minimum error rate.

Abstract

This research dives into the complex dynamics between information technology, organizational culture, and employees at bfreshgigi, a dental health company that is transforming in the digital era. Through in-depth interviews with six employees from various positions, the study reveals how information technology is not just a tool, but a fundamental game changer. Organizational culture emerged as a critical counterweight, sometimes supporting innovation, but sometimes hampered by hierarchical structures. Employee performance was found to go far beyond mere productivity, encompassing adaptability and creativity. The findings suggest that alignment between technology, culture and performance is critical; when aligned, the results are outstanding, but imbalances can trigger stress and demoralization. This study not only enriches theoretical understanding but also offers practical insights for organizations struggling with digital transformation.
