Abstract

Provinsi Sumatera Selatan merupakan salah satu kontributor utama dalam produksi beras di Indonesia. Pada tahun 2021, proyek pertanian yang dikenal dengan sebutan "food estate" diresmikan di lima kabupaten di Sumatera Selatan, yaitu Ogan Ilir, Ogan Komering Ilir, Banyuasin, Ogan Komering Selatan, dan Ogan Komering Ulu Timur (OKU Timur). Namun, rencana ini menimbulkan masalah mulai dari peraturan, modal, hingga masalah lingkungan. Penelitian ini menerapkan model ARIMA, yang singkatan dari Auto Regressive Integrated Moving Average Model, sebagai metode peramalan. Hasil peramalan menunjukkan bahwa peningkatan dari tahun 2023 hingga 2030 mengalami peningkatan signifikan. Beberapa strategi utama melibatkan teknologi pertanian modern, pelatihan petani, pengelolaan udara yang efisien, pemupukan yang tepat, pengendalian hama dan penyakit, investasi infrastruktur, diversifikasi produk pertanian, pengembangan tambah nilai, dan pentingnya pemantauan dan evaluasi. Rekomendasi dalam penelitian ini berupa partisipasi modal dalam program, bantuan dan pemantauan dari pemerintah, peraturan yang jelas, ketersediaan input tepat waktu, jumlah, dan harga yang sesuai, penanaman terjadwal, dan penyimpanan untuk stabilitas produk.

Abstract

The development of satellite data has played an important role in monitoring natural disasters on the Earth's surface. Providing an overview of the current conditions of a volcanic crisis, including information on lava flow extension, is a challenge in observing volcanoes. Various methods were used to map lava flows, such as identifying lava on optical satellite images and detecting thermal anomalies emitted by hot lava. This study aimed to generate a preliminary map of active lava flow caused by the 2022 Mauna Loa eruption in near real-time by analyzing fire radiative power (FRP) data acquired from Suomi National Polar-orbiting Partnership (S-NPP) and National Oceanic and Atmospheric Administration-20 (NOAA-20) satellites. FRP data was filtered to identify lava flow using statistically determined thresholds from its value distribution, including the 5th percentile, 3rd quartile, mean, and 95th percentile. The obtained active lava flow map is evaluated using confusion matrix analysis by comparing the estimated map with the reference map. The maps generated using various thresholds were compared, and the best result was provided by the threshold of the 3rd quartile, with S-NPP and NOAA-20 FRP threshold values of 27.2 and 27.9 MW/pixel, respectively, with overall accuracy reaching 97%. The higher threshold reduced the overestimated lava location represented by a false positive (FP) value. The results show that the active lava originated from the summit caldera, and the eruptive fissure on the northeast flank extended to the northeastern area with an estimated daily distance reaching about 18 km from a certain reference point. This preliminary lava flow map can provide general information regarding areas prone to lava flows, especially around Mauna Loa, and support related parties in updating hazard zones rapidly. The findings should help make immediate decisions for evacuation routes and public warnings when an eruption occurs without visiting the volcanic area directly.

Abstract

Abstract: This study aims to describe students' mathematical communication skills in solving comparison problems. A total of 32 sixth-grade students at AlWashliyah 80 Kisaran Private Elementary School were the subjects of this study. Data were collected by giving three essay questions focusing on comparison material. The results of the analysis showed that only a small percentage of students, namely 18.75%, had high mathematical communication skills. Another 25% were in the moderate category, while the majority of students, 56.25%, were classified as having low communication skills. Students in the high category were able to meet all the expected indicators, while students in the moderate category were only able to master two indicators. Students in the low category were generally only able to achieve one indicator. These findings confirm that mathematical communication skills play an important role in helping students understand problems and solve math questions more effectively.Keywords: Analysis; ability; mathematical communication; comparison.Abstrak: Penelitian ini bertujuan menggambarkan kemampuan komunikasi matematis siswa dalam menyelesaikan soal perbandingan. Sebanyak 32 siswa kelas VI di SD Swasta AlWashliyah 80 Kisaran menjadi subjek dalam penelitian ini. Data dikumpulkan melalui pemberian tiga soal uraian yang berfokus pada materi perbandingan. Hasil analisis menunjukkan bahwa hanya sebagian kecil siswa, yakni 18,75%, yang memiliki kemampuan komunikasi matematis pada kategori tinggi. Sebanyak 25% lainnya berada pada kategori sedang, sedangkan mayoritas siswa, yaitu 56,25%, tergolong memiliki kemampuan komunikasi yang rendah. Siswa yang termasuk kategori tinggi mampu memenuhi seluruh indikator yang diharapkan, sementara siswa yang berada pada kategori sedang hanya dapat menguasai dua indikator. Adapun siswa dengan kategori rendah umumnya hanya mampu mencapai satu indikator saja. Temuan ini menegaskan bahwa kemampuan komunikasi matematis memegang peran penting dalam membantu siswa memahami persoalan dan menyelesaikan soal matematika secara lebih efektif.Kata kunci: Analisis; kemampuan; komunikasi matematis; perbandingan.
