Abstract

Seiring dengan kemajuan teknologi informasi dan memasuki era revolusi industri 4.0, pemanfaatan teknologi dalam aktivitas manusia semakin meningkat. Data kini menjadi aset berharga, dan kemampuan dalam mengumpulkan, menganalisis, serta menginterpretasi data telah menjadi keterampilan krusial dalam dunia kerja dan pendidikan. Pendidikan memainkan peran penting dalam mempersiapkan generasi mendatang untuk menghadapi tantangan global yang semakin kompleks. Di SMAN 1 Kembang Kabupaten Jepara, terdapat beberapa masalah utama, yaitu keterbatasan akses dan pemahaman siswa mengenai data, kurangnya pengalaman dalam visualisasi data, dan minimnya pemahaman tentang manfaat visualisasi data. Program pelatihan ini bertujuan untuk meningkatkan pemahaman siswa mengenai data dan teknik visualisasi melalui penyampaian materi konseptual tentang konsep data dan visualisasi, penggunaan Google Data Studio, dan pembuatan dashboard visualisasi. Pelaksanaan PKM ini menggunakan metode interaktif dan demontrasi kepada siswa kelas 11 SMAN 1 Kembang sebanyak 20 orang. Hasil PKM menunjukkan bahwa siswa mampu meningkatkan pemahaman mereka tentang konsep dasar data, jenis-jenis data, dan pentingnya visualisasi data. Siswa juga menunjukkan kemajuan yang baik dalam keterampilan teknis terkait penggunaan Google Data Studio untuk mengolah dan memvisualisasikan data. Mereka berhasil menerapkan berbagai fitur untuk menyusun grafik, diagram, dan visualisasi lain yang sesuai dengan data yang diberikan. Hasil visualisasi ini memperlihatkan kemampuan siswa dalam menyajikan data dengan cara yang informatif dan menarik.

Abstract

Data mining merupakan suatu metode yang baik untuk menangani data skala besar. Performasi menjadi penting dalam metode data mining. Salah satu metode yang memiliki performasi terbaik adalah K-Nearest Neighbor (KNN). Artikel ini membahas terkait performasi K-NN. Data yang digunakan pada penelitian ini adalah Diabetes. Data dibagi menjadi 80% data trainingdan 20% data testing. Dengan menggunakan 11 tetangga terdekat, model menghasilkan akurasi sebesar 0.765625. Angka ini mencerminkan kinerja yang baik. Metrik kritis termasuk akurasi sebesar 0.77, presisi sebesar 0.80, dan recall sebesar 0.85. Hasil ini menunjukkan bahwa model KNN memiliki potensi untuk mengklasifikasikan pasien diabetes dengan akurasi yang baik.

Abstract

Infrastructure development is a strategic element in improving public services and economic growth. South Sumatra Province, with its large economic potential, faces challenges in managing efficient and sustainable infrastructure development. This research aims to apply the Fuzzy Gustafson Kessel (FGK) method in decision making related to infrastructure development in South Sumatra Province. FGK combines fuzzy logic with Gustafson Kessel clustering algorithm to handle uncertainty and data variation from various stakeholders. The data used in this study includes population and geographic census data from the Central Bureau of Statistics of South Sumatra Province in 2023, with five indicators: population, area, population growth rate, population density, and poverty rate. The results show that South Sumatra is divided into three main clusters based on its infrastructure and demographic characteristics. This clustering is expected to improve the effectiveness and efficiency of infrastructure development decision-making, provide more appropriate policy recommendations, and potentially be applied in other regions with similar challenges.

Abstract

This study aims to analyze the factors influencing the Human Development Index (HDI) in West Java Province using the Geographically Weighted Regression (GWR) approach. The independent variables used in this study are the Open Unemployment Rate (TPT), School Participation Rate for ages 16–18 (APS_16_18), Population Density, and Gross Regional Domestic Product per Capita (PPK). The modeling was carried out by comparing various kernel functions, namely Gaussian, Bisquare, and Tricube, as well as two bandwidth approaches: fixed and adaptive. The results indicate that the GWR model with a Gaussian kernel and a fixed bandwidth approach provides the best performance based on the lowest AIC value. Compared to the classical Ordinary Least Squares (OLS) model, the GWR model offers a better explanation of spatial variation in HDI across the study area. Although the GWR model was not statistically significant overall based on the ANOVA test, local analysis showed that the variables TPT and PPK had significant effects in all districts and cities, while APS_16_18 and Population Density were not significant in any region. These findings demonstrate that the GWR model is capable of capturing spatial heterogeneity that is not detected by the global regression model.
