Abstract

Remaja masjid di Yayasan Sabilul Mutaqin berusia 12-24 tahun, dimana rentang usia ini merupakan kelompok dengan tingkat penetrasi internet tertinggi. Usia remaja sangat penting sekali untuk belajar literasi digital sebagai bekal menjalani kehidupan sehari-hari agar dapat lebih baik mengelola kehidupan digital mereka, mengurangi risiko online, dan memanfaatkan teknologi dengan cara yang bermanfaat bagi perkembangan pribadi dan sosial mereka. Level literasi digital di Indonesia saat ini sekitar 62%, angka yang lebih rendah jika dibandingkan dengan rata-rata level literasi digital di negara-negara ASEAN lainnya. Sehingga kegiatan pengabdian kemasyarakatan ini sangatlah penting untuk menaikkan level literasi di kalangan remaja terutama pada aspek etika digital dan budaya digital. Hal ini sejalan dengan program Gerakan Nasional Literasi Digital untuk meningkatkan keterampilan digital masyarakat Indonesia yang dilakukan oleh Kementerian Kominfo dengan menyasar salah satu segmennya, yaitu masyarakat umum terutama remaja. Solusi yang dipilih adalah pemberian pembekalan dan pelatihan literasi digital, terutama pada dua aspek utama, yaitu etika digital (digital ethics) dan budaya digital (digital culture) yang islami dalam pelaksanaannya. Hasil kegiatan kami dengan adanya kegiatan ini adalah peserta menyadari pentingnya literasi digital dan dapat menerapkan penggunaan sosial media dengan bijak sesuai etika (dapat membedakan mana konten negatif dan positif), dan budaya islami (mengetahui pentingnya moderasi beragama sebagai warga negara).

Abstract

In the context of Sleman Regency, Indonesia, the rate of drug abuse is increasing due to insufficient dissemination of information about the types of drugs and the negative impacts resulting from drug abuse. One of the contributing factors is the lack of socialization among the community, leading to their limited knowledge about the types of drugs and the dangers of improper use or using medication without a doctor's prescription. The approach applied to combat this problem is a systematic method that involves planning the system, analysis, design, implementation, testing, and maintenance. These steps must be carried out in a sequential manner. The system itself will be developed using programming languages such as PHP, JavaScript, and MySQL server for data processing

Abstract

This study examines user sentiment towards online vehicle tax renewal applications by utilizing the Support Vector Machine (SVM) algorithm. The data was collected from user reviews on the Google Play Store for three major applications: New Sakpole, Sapawarga, and Timsalut. The reviews were preprocessed through steps including normalization, case folding, tokenization, and stopword removal. The SVM algorithm was then applied to classify the reviews into positive or negative sentiments. A comparative analysis was performed with K-Nearest Neighbors (KNN) and Naïve Bayes, with SVM demonstrating the best performance, achieving an accuracy of 76.5%. In addition to accuracy, metrics such as precision, recall, and F1-score were also evaluated to provide a more comprehensive assessment of the models. The results indicate that while these applications help facilitate vehicle tax payments, there remains significant user dissatisfaction, particularly related to technical issues and usability concerns. This study offers valuable insights for application developers, highlighting areas for improvement in functionality and user experience to better meet public expectations.

Abstract

This study aims to compare the performance of three clustering algorithms, namely Fuzzy C-Means, K-Means, and DBSCAN, in grouping houses based on their specifications and prices. The data used includes features such as price, building area, land area, number of bedrooms, number of bathrooms, and availability of garages. The performance of these algorithms was evaluated using Silhouette Score and Davies-Bouldin Score to determine the quality of cluster separation. The results indicate that K-Means achieved the best performance with the highest Silhouette Score of 0.7702 for two clusters, followed by Fuzzy C-Means, which excelled in handling overlapping clusters. DBSCAN, while effective in detecting outliers, showed suboptimal performance for this housing dataset. These findings suggest that K-Means is the most suitable clustering method for housing data, while Fuzzy C-Means and DBSCAN can serve as alternatives depending on the data characteristics. This research is expected to assist in making the house searching and classification process more efficient and provide additional insights for developers in shaping housing market strategies.

Abstract

The warning of a global recession expected in 2023 is currently the world's concern. Global financial institutions have raised interest rates to lower inflation, which has led to this problem. This study aims to evaluate the effect of interest rates and inflation on Indonesia's economic growth and compare the performance of machine learning models, specifically Random Forest and XGBoost, in analyzing the impact of inflation. A qualitative methodology was used for the literature survey, while the quantitative approach involved the implementation of machine learning algorithms using the Ensemble Method. The results show that Random Forest performs better than XGBoost in predicting the impact of inflation on economic growth, with MSE values of 0.799 and 0.864 and MAE of 0.576 and 0.619, respectively. In addition, the R-squared value of Random Forest 0.908 is also higher than that of XGBoost 0.901, indicating that the model can better explain the variation in the target data. The practical implication of this study is that the Random Forest model can be more effectively used in analyzing the impact of inflation on Indonesia's economic growth. Recommendations for future research include exploring other methods and using more extended time series to deepen the understanding of the relationship between interest rates, inflation, and economic growth.

Abstract

Alzheimer's disease is a type of neurodegenerative disorder that causes a decline in cognitive function. Early detection is crucial to enable more effective interventions and slow the progression of the disease. However, the diagnosis of Alzheimer's disease often faces challenges, particularly in detecting the early stages of the disease from complex and diverse medical data. This study aims to optimize the Random Forest algorithm using the Random Search method for detecting Alzheimer's disease. The Random Forest algorithm was applied as the primary model in this research, while hyperparameter optimization was performed using the Random Search method to improve model performance. The results showed that the Random Forest model without optimization achieved an accuracy of 96%. After performing hyperparameter optimization, the model's accuracy increased to 97%. In conclusion, the application of hyperparameter optimization using the Random Search method successfully enhanced the performance of the Random Forest model. The resulting model provides more accurate predictions, making it a reliable tool for the early detection of Alzheimer's disease.

Abstract

Covid-19 or Coronavirus is a virus that is found in humans and animals. This virus can infect humans to cause various diseases such as flu, to serious diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). In Indonesia, the spread of Covid-19 cases continues to increase and is evenly distributed in all provinces in Indonesia because of the fairly rapid spread due to the vast area in Indonesia, making it possible for grouping based on regions in Indonesia to be needed which will result in the center points of the spread of this Covid-19 case. This study aims to group Covid-19 data into a cluster using the K-Means Clustering Data Mining Algorithm. The Covid-19 data used in this study is Covid-19 data on July 6, 2021 which was taken from the official website of Kawal Covid-19 (KawalCovid-19.id). The attributes used are positive cases, recovered, and died. The clusters formed from the results of research using K-Means Clustering are 3 clusters with the first cluster consisting of 2 provinces, the second cluster 3 provinces, and for the third cluster 29 provinces. The cluster with the largest Covid-19 spread rate is cluster one. From this study, the accuracy was 91.176% and evaluated using the Davies-Bouldin Index yielded a fairly good cluster result with a value of 0.493371469.
