Abstract

Salah satu hal yang menyebabkan rendahnya hasil belajar siswa kelas VI IPAS SDN Sidosermo I/427 Surabaya adalah masih digunakannya metode pembelajaran tradisional. Tujuan utama penelitian ini adalah untuk meningkatkan pemahaman siswa kelas VI tentang rangka tubuh manusia melalui penggunaan teknik pembelajaran kooperatif tipe STAD. Penelitian kelas ini menggunakan dua siklus. Dalam proses pengumpulan data digunakan tes dan observasi. Berdasarkan hasil penelitian, siklus I memperoleh rata-rata 46 dengan daya serap 46%, sedangkan siklus II memperoleh rata-rata 82 dengan daya serap 82%. Hal ini menunjukkan bahwa pemahaman siswa terhadap materi Rangka tubuh Manusia mengalami peningkatan. Dengan demikian, pada kelas VI SD Negeri Sidosermo I/427 Surabaya, penerapan pendekatan pembelajaran kooperatif tipe STAD dapat meningkatkan pemahaman siswa terhadap materi IPAS yang dibuktikan dengan meningkatnya hasil belajar siswa.

Abstract

This study aims to analyze a comparison of coal stockpile volumes using the DJI Mavic 3 Pro Unmanned Aerial Vehicle (UAV) method versus the truck count method at PT. Mitra Barito. Data collection was conducted through aerial photography using a UAV at altitudes of 60 meters and 70 meters, as well as Ground Control Point (GCP) measurements using GPS. The aerial imagery data was processed using photogrammetry software to generate orthophotos and a Digital Elevation Model (DEM), followed by a geometric accuracy test based on the Geospatial Information Agency Regulation No. 6 of 2018, using the Circular Error 90% (CE90) and Linear Error 90% (LE90) parameters. The research results show that high-quality processing at an altitude of 60 meters yields a CE90 value of 2.1619 meters and an LE90 value of 4.3656 meters, thereby meeting the accuracy standards for RBI maps at a scale of 1:5,000, Class 3 for horizontal accuracy, and a scale of 1:10,000, Class 3 for vertical accuracy. Volume calculations of the stockpile using UAVs yielded a result of 22,750.900 m³, while the truck count method produced a volume of 23,503.300 m³. The volume difference between the two methods was 753.400 m³, with a deviation percentage of 3.2%. Based on the research results, the UAV method is considered capable of providing relatively accurate calculations of coal stockpile volume.

Abstract

The distance learning policy is the best effort to minimize the spread of Covid-19 in schools. This study aims to see the response of students in distance learning in the 2013 curriculum. The research method used is a descriptive quantitative method and the data source is obtained from questionnaires given to 156 students in 12 elementary schools spread across 7 regencies/cities of East Java. The results showed that 100 percent of students took distance learning as scheduled, 51.3 percent of students accompanied by mothers, 10.3 percent of students accompanied by fathers, 20.5 percent of students accompanied by guardians, and 17.9 percent of students had no companions while studying. The communication tools used showed that 92.9 percent used social media, 71.8 percent of students found it difficult to understand thematic learning, 49.4 percent of the student assignment collection places were social media, and 92.9 percent of students thought distance learning added to technological knowledge.
