Abstract

MTsS Harapan Bangsa membuka kelas berbasis teknologi informasi sebagai upaya meningkatkan kualitas pembelajaran melalui sistem kelas digital. Namun, pelaksanaannya menghadapi kendala, terutama keterbatasan perangkat dan biaya tambahan seperti kebutuhan smartphone, paket data, serta langganan aplikasi Jelajah Ilmu yang mencapai ratusan ribu rupiah per tahun. Kondisi ini menimbulkan beragam persepsi dari orang tua siswa. Penelitian ini menggunakan metode deskriptif kualitatif dengan subjek kepala madrasah, guru kelas, dan orang tua siswa kelas digital. Data dikumpulkan melalui observasi, wawancara, dan dokumentasi, kemudian dianalisis menggunakan teknik analisis kualitatif. Hasil penelitian menunjukkan bahwa pelaksanaan kelas digital dimulai dengan pembelian akses aplikasi Jelajah Ilmu oleh siswa. Guru memanfaatkan aplikasi tersebut dalam proses belajar mengajar dengan menampilkannya melalui infokus, sementara materi dapat diakses langsung oleh siswa tanpa perlu mencatat atau membeli buku paket. Sistem ini membantu siswa belajar lebih praktis dan mendorong penguasaan teknologi. Persepsi orang tua menunjukkan adanya manfaat seperti kemudahan akses materi, peningkatan motivasi belajar, perluasan wawasan, dan peningkatan kemampuan teknologi. Namun, mereka juga menilai bahwa kelas digital menambah beban biaya pendidikan.

Abstract

Rising atmospheric CO₂ emissions from fossil fuel-based industries have intensified the need for effective mitigation strategies, with Carbon Capture and Storage (CCS) in geological formations, particularly un-mined coal seams necessitates specialized research into numerous critical factors that are equivalent thorough characterization of coal properties such as porosity, permeability, uniaxial compressive strength (UCS), poisson ratio, and brittleness. This study serves as a preliminary assessment of the CCS potential of Coal Seam D in the Suban Burung Block, South Sumatra Basin, using drilling data from four wells (within area 960 m × 860 m). This study aims to describe the coal seam D strata for underground CO2 storage. Coal Seam D was identified from core sample data, with laboratory analyses conducted to determine density and porosity values. Then, in this study we predict velocity (Vp and Vs), UCS values, and BI using petrophysical and rock physics approaches. The analysis by integrates well correlation, estimation of elastic and mechanical parameters, and spatial interpolation of petrophysical properties. Results indicate that Coal Seam D has a thickness of 8.1–10.7 m and porosity ranging from 0.14–0.198. Mechanical properties show Uniaxial Compressive Strength (UCS) values of 9.5-9.7 MPa and a Brittleness Index 0.47–0.50 which indicate coal with low to medium strength and medium brittleness. Based on the preliminary analysis, the coal seam D in this region exhibits favorable candidate for implementation CO₂ storage in South Sumatra, Indonesia.
