Abstract

Program pemberdayaan siswa dalam literasi kebencanaan melalui edukasi mitigasi bencana berbasis kolaboratif di SMPN 1 Bolango Selatan dilaksanakan sebagai upaya meningkatkan kesiapsiagaan dan kemampuan siswa dalam menghadapi potensi bencana di wilayah yang memiliki kerentanan tinggi. Program ini dirancang melalui empat tahapan utama, yaitu analisis kebutuhan dan pemetaan risiko, pembelajaran partisipatif berbasis kelas, pelatihan serta simulasi respons darurat. Hasil pelaksanaan menunjukkan peningkatan signifikan pada aspek pengetahuan, keterampilan teknis, dan sikap kesiapsiagaan siswa. Siswa mampu mengenali tanda-tanda awal bencana, memahami jalur evakuasi, melakukan tindakan mitigasi sederhana, serta melaksanakan pertolongan pertama dasar. Pendekatan kolaboratif terbukti efektif dalam menghadirkan pengalaman belajar autentik melalui interaksi langsung dengan praktisi kebencanaan dan lingkungan nyata. Program ini juga mendorong terbentuknya budaya sadar bencana di lingkungan sekolah, serta membuka peluang replikasi di sekolah lain yang memiliki risiko bencana serupa. Secara keseluruhan, program ini berkontribusi pada peningkatan ketangguhan sekolah dan masyarakat melalui pemberdayaan siswa sebagai agen kesiapsiagaan bencana.

Abstract

Danau Limboto mengalami permasalahan sedimentasi yang signifikan akibat erosi daerah aliran sungai (DAS). Sedimen Danau Limboto (SDL) yang terakumulasi di dasar danau berupa material lempung halus yang selama ini belum dimanfaatkan secara optimal. Penelitian ini bertujuan untuk menjelaskan teknik pembuatan paving block berbasis Sedimen Danau Limboto (SDL) dengan penambahan biochar sekam padi 5%, 7,5% dan 10%. Tahapan penelitian meliputi pengambilan dan pengolahan sedimen, proses pirolisis sekam padi menjadi biochar, pencampuran, pencetakan paving block, serta perawatan paving block. Hasil penelitian menunjukkan bahwa nilai kuat tekan tertinggi diperoleh Formula 3 dengan variasi biochar 5% yaitu sebesar 7,25 MPa. Hal tersebut menunjukan bahwa Sedimen Danau Limboto (SDL) berpotensi digunakan sebagai bahan alternatif paving block, sedangkan biochar sekam padi berkontribusi terhadap karakteristik material yang lebih ramah lingkungan dan berpori. Teknik pembuatan yang tepat berpengaruh signifikan terhadap mutu paving block yang dihasilkan.

Abstract

Soil erosion is a major problem on sloping land that can reduce soil fertility and agricultural productivity. This study aims to analyze the effectiveness of palm fiber (ijuk) nets and corn plants in controlling soil erosion on land with a slope of approximately 57° in Bina Jaya Village, Tolangohula District, Gorontalo Regency. The method used was a field experiment with three treatments: Plot I (ijuk net + corn), Plot II (ijuk net), and Plot III (without treatment). The observed data included rainfall, soil erosion mass, and corn growth used to calculate the Leaf Area Index (LAI). The results showed that Plot I produced the lowest soil erosion (16.8 kg), followed by Plot II (23.7 kg), and Plot III (84.5 kg). Rainfall had a direct influence on increasing soil erosion, especially on untreated land. Increasing LAI values contributed to reducing erosion by improving soil cover and reducing runoff. The effectiveness of the ijuk net reached 80.1% when combined with vegetation and 71.9% without vegetation. Therefore, the combination of ijuk net and corn plants is proven to be an effective, simple, economical, and sustainable soil conservation method for sloping land.

Abstract

This research investigates the exact solution of the Kantowski-Sachs metric within the framework of  gravity theory, with the matter distribution described as a perfect fluid. The  gravitational field equations are first derived using the modified Einstein-Hilbert action principle. Next, the system of field equations is solved by applying the assumption that the expansion scalar  is proportional to the shear scalar , thus obtaining a relationship between the Kantowski-Sachs metric coefficients. The obtained solution is used to analyze several physical parameters, including the Hubble parameter , spatial volume , expansion scalar , shear scalar , deceleration parameter , and jerk parameter . The results show that the model describes an anisotropic universe that begins from a Big Bang-type singularity, undergoes a decelerating expansion phase, and produces a jerk parameter value greater than the prediction of the  model. These findings indicate a deviation in the expansion dynamics of the early universe, although the interpretation is still limited by the assumption of proportionality  and the selection of a specific form of the function . Therefore, further testing of observational data is necessary to assess the validity of this model.

Abstract

Terrestrial nuclear radiation is natural radiation originating from the decay of radionuclides in rocks and soil, with a distribution influenced by the geological and geomorphological conditions of the region. Peling Island, Banggai Islands Regency, is dominated by karst areas that have the potential to influence the distribution of terrestrial nuclear radiation, but spatial information regarding radiation in this region is still limited. This study aims to analyze the spatial distribution of terrestrial nuclear radiation dose rates in the eastern region of Peling Island. Measurements were carried out at 144 sample points systematically distributed using an observation grid measuring 1500 m × 1500 m. At each point, a Pocket Geiger Type 6 detector was placed at a height of ±1 m above the ground surface and connected to a smartphone via the Pocket Geiger Type 6 application. Data were recorded every 2 minutes, and stored in CSV and KML formats. The data were then processed using two software, namely, ArcgGIS with the IDW method and Python for spatial classification and analysis. The results showed a uniform distribution of radiation dose rates without any spikes or extreme differences between measurement areas, with a range of ≤0.02 to 0.14 µSv/h and an average of 0.0504 µSv/h. The annual effective dose was recorded at 0.0883 mSv/y. This value is still below the effective dose limit for the general public of 1 mSv/y.
