Abstract

This study examines the multivariate relationship between educational social media utilization (Set X: X₁ = frequency of use, X₂ = active participation in educational activities, X₃ = creativity in creating language-related content, X₄ = content utilization for language learning) and productive language skills (Set Y: Y₁ = creative writing in digital media, Y₂ = speaking in digital media, Y₃ = debating in digital contexts, Y₄ = constructing multimodal texts) among senior secondary school students. Employing a quantitative, multivariate correlational design, 200 eleventh-grade students from SMAN 6 Tangerang Regency were selected via purposive sampling. Data were collected through validated Likert-scale questionnaires and productive language performance tasks administered online via Google Form during September 2025. Instrument reliability was established via Cronbach’s α (0.81–0.89) and McDonald’s ω (0.82–0.88), with content validity confirmed by three language education experts. Canonical Correlation Analysis (CCA) was conducted using SPSS 27, yielding four canonical functions with canonical correlations (Rc) of 0.580, 0.490, 0.258, and 0.077, respectively. Wilks’ Lambda tests confirmed that the first three canonical functions were statistically significant (overall Λ = 0.468, p < .001; Λ = 0.705, p < .001; Λ = 0.928, p = .006), while the fourth was not (Λ = 0.994, p = .280). Analysis of canonical structure coefficients revealed that Canonical Function 1 was predominantly defined by X₂ (r = 0.874) and Y₄ (r = 0.902); Function 2 by X₃ (r = −0.940) and Y₂ (r = 0.948); and Function 3 primarily by Y₃ (r = −0.983). These findings collectively indicate that students who engage more actively and creatively in educational social media activities demonstrate superior productive language competencies, particularly in multimodal composition and digital speaking, underscoring the pedagogical value of structured social media integration in secondary language education.

Abstract

This study analyzes flood vulnerability in the Angke-Pesanggrahan Watershed, Jakarta, which faces increased risks due to land-use changes. The study aims to calculate the 50-year return period flood discharge, map flood-prone zones, and formulate mitigation recommendations using spatial mapping. A quantitative approach was employed, analyzing 15 years of rainfall data from five stations. Methodology included data consistency testing, Spearman’s correlation, stationarity, and outlier identification, followed by regional rainfall analysis using Thiessen Polygons. The Log Pearson Type III distribution was applied for frequency analysis, and the Nakayasu Synthetic Unit Hydrograph method estimated flood discharge. Flood-prone zones were mapped using scoring and overlay techniques in a Geographic Information System (GIS). Results show that the 50-year flood discharge reaches 1.128 m3/s, exceeding existing river capacity. Mapping simulations identified flood depths of 3–6 meters in downstream areas, with high-risk zones concentrated in Northern Kembangan, Kedaung Kali Angke, Kapuk Muara, Kamal Muara, Eastern Cengkareng, and Northern Kedoya, where surface runoff contributes up to 90%. Spatial analysis categorized 257.18 km2 as non-prone, 92.14 km2 as moderately prone, 75.75 km2 as prone, and 58.57 km2 as highly prone. This study concludes that the Angke-Pesanggrahan Watershed, particularly the Cengkareng Drain section, requires urgent technical intervention, including river normalization and catchment area optimization. These findings provide a crucial spatial database for sustainable flood mitigation and risk-based decision-making in urban planning.

Abstract

Penelitian ini bertujuan untuk menganalisis konsentrasi karbon dioksida (CO₂) di kawasan industri Kota Cilegon, mengkaji distribusi spasialnya, serta mengidentifikasi wilayah dengan tingkat konsentrasi tertinggi guna mendukung pengelolaan lingkungan. Metode yang digunakan adalah deskriptif kuantitatif dengan pendekatan observasional berbasis data sekunder yang diperoleh dari PT Krakatau Sarana Infrastruktur (KSI) dan BMKG selama periode 2020–2024 dalam bentuk deret waktu (time series). Analisis data meliputi statistik deskriptif, uji normalitas Kolmogorov-Smirnov, uji korelasi Spearman, serta analisis temporal untuk mengidentifikasi pola dan tren perubahan konsentrasi CO₂. Hasil penelitian menunjukkan bahwa rata-rata konsentrasi CO₂ sebesar 415,675 ppm dengan tren peningkatan sebesar ±2,27% dari tahun 2020 hingga 2024. Analisis menunjukkan bahwa suhu memiliki hubungan positif sedang dan signifikan terhadap konsentrasi CO₂ (ρ = 0,427), sedangkan variabel meteorologi lainnya tidak menunjukkan pengaruh signifikan. Selain itu, analisis temporal memperlihatkan adanya peningkatan konsentrasi CO₂ secara konsisten, yang mengindikasikan akumulasi emisi di atmosfer, serta menunjukkan adanya variasi distribusi yang dipengaruhi oleh aktivitas industri. Implikasi penelitian ini menegaskan pentingnya pengendalian emisi berbasis wilayah serta pemanfaatan analisis spasial sebagai dasar dalam pengambilan kebijakan yang lebih efektif dan berkelanjutan dalam pengelolaan kualitas udara.

Abstract

Kabupaten Serang merupakan salah satu wilayah yang memiliki potensi tinggi terhadap bencana tanah longsor. Kondisi ini dipengaruhi oleh karakteristik topografi yang bervariasi, mulai dari dataran rendah hingga kawasan perbukitan dengan lereng yang curam. Variasi morfologi tersebut menyebabkan perbedaan tingkat kestabilan lahan, sehingga beberapa area menjadi lebih rentan terhadap pergerakan tanah. Penelitian ini bertujuan untuk menganalisis dan memetakan tingkat kerawanan tanah longsor di Kabupaten Serang dengan menggunakan metode SMORPH (Slope Morphology), yang berfokus pada parameter bentuk lereng dan kemiringan lereng sebagai indikator utama potensi longsor. Dalam penelitian ini, pengolahan data dilakukan dengan memanfaatkan perangkat lunak ArcGIS 10.8. Peta kemiringan lereng dihasilkan menggunakan tools slope, sedangkan peta bentuk lereng diperoleh melalui tools curvature. Kedua peta tersebut kemudian dioverlay untuk menghasilkan peta tingkat kerawanan longsor berdasarkan klasifikasi matriks SMORPH. Pendekatan ini memungkinkan identifikasi wilayah rawan longsor secara lebih sistematis dan spasial. Hasil analisis menunjukkan bahwa sebagian besar wilayah Kabupaten Serang tergolong dalam kategori kerawanan longsor rendah dengan luas mencapai 107.670,74 hektar atau sekitar 73,47% dari total wilayah. Sementara itu, kategori kerawanan sedang mencakup luas 20.173,75 hektar atau sebesar 13,77%. Adapun wilayah dengan tingkat kerawanan tinggi memiliki luas 8.701,82 hektar atau sekitar 12,76%. Daerah dengan kerawanan tinggi umumnya tersebar di Kecamatan Bojonegara, Mancak, dan Padarincang, yang didominasi oleh kemiringan lereng yang curam. Hasil penelitian ini diharapkan dapat menjadi dasar dalam upaya mitigasi bencana serta perencanaan tata ruang wilayah yang lebih aman dan berkelanjutan.

Abstract

Background Problems: The critical importance of maintaining physical fitness among high school students to mitigate the potential health hazards associated with a sedentary lifestyle. Research Objectives: This study aims to explore the impact of futsal and hadang extracurricular activities on adolescent cardiovascular and respiratory fitness. Methods: This research used an experimental study with pre-post design and control group. Ninety students from Serang City high schools were divided into three groups: Futsal Extracurricular, Hadang Extracurricular, and Control. Initial assessments established baseline fitness levels, followed by an 8-weeks program and post-program evaluations. Findings and Results: The results showed an increase in aerobic capacity and respiratory capacity after 8-weeks extracurricular program in both groups. The futsal extracurricular group experienced a higly significant increase aerobic capacity and respiratory capacity compared to the baseline. Meanwhile, the hadang extracurricular group experienced a significant increase aerobic capacity and respiratory capacity compared to the baseline. Conversely, the control group appears to exhibit a decline in both aerobic and respiratory capacities, although it is important to note that these changes did not reach statistical significance in our study. Conclusion: In conclusion, this study provided valuable insights into how futsal and hadang extracurricular activities impact adolescent cardiovascular and respiratory fitness. These findings were relevant for educators and policymakers, highlighting the role of extracurricular programs in enhancing students' overall well-being. Additionally, it contributes to our understanding of how specific activities can influence the cardiovascular and respiratory health of adolescents.
