EFEKTIVITAS MODEL PEMBELAJARAN SEARCH, SOLVE, CREATE AND SHARE (SSCS) UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS SISWA KELAS X MAN YOGYAKARTA I PADA MATERI ALAT-ALAT OPTIK

Telah dilakukan penelitian eksperimen untuk mengetahui perbedaan keterampilan berpikir kritis antara siswa yang mengikuti model pembelajaran Search, Solve, Create and Share (SSCS) dan siswa yang mengikuti model pembelajaran ekspositori, serta untuk mengetahui efektivitas model pembelajaran SSCS untuk meningkatkan keterampilan berpikir kritis siswa pada materi Alat-Alat Optik. Populasi dalam penelitian ini adalah siswa kelas X MIA MAN Yogyakarta I Tahun Ajaran 2014/2015. Pengambilan sampel dengan teknik simple random sampling. Teknik pengumpulan data yang digunakan adalah tes, dan instrumen berupa soal pretest dan posttest. Teknik analisis data yang digunakan adalah statistik parametrik berupa uji-t, normalized gain (N-gain) serta ukuran efek. Hasil penelitian menunjukkan bahwa perbedaan rata-rata skor posttest kelompok eksperimen dan kontrol menunjukkan nilai sig.(2-tailed) sebesar 0,000 lebih kecil dari taraf signifikansi 0,05, sehingga disimpulkan bahwa model pembelajaran SSCS efektif untuk meningkatkan keterampilan berpikir kritis siswa dalam materi Alat-Alat Optik. Cacah siswa yang lulus dengan nilai ≥ 65 sebanyak 23 siswa (85,19%) dan nilai N-gain kelas eksperimen (0,64) lebih besar dari nilai N-gain kelas kontrol (0,45), dan keduanya berada diklasifikasi sedang. Ukuran efek berada pada klasifikasi tinggi, yaitu sebesar 1,073.Kata kunci: model SSCS, keterampilan berpikir kritis, Alat-Alat Optik

A Simple Aerial Photogrammetric Mapping System Overview and Image Acquisition Using Unmanned Aerial Vehicles (UAVs)

Aerial photogrammetry is one of the Alternative technologies for more detailed data, real time, fast and cheaper. Nowadays, many photogrammetric mapping methods have used UAV / unmanned drones or drones to retrieve and record data from an object in the earth. The application of drones in the field of geospatial science today is in great demand because of its relatively easy operation and relatively affordable cost compared to satellite systems especially high - resolution satellite imagery.  This research aims to determine the stage or overview of data retrieval process with DJI Phantom 4 (multi - rotor quad - copter drone) with processing using third party software. This research also produces 2 - dimensional high resolution image data on the research area. Utilization of third party software (Agisoft PhotoScan) making it easier to acquire and process aerial photogrammetric data. The results of aerial photogrammetric recording with a flying altitude of 70 meters obtained high resolution images with a spatial resolution of 2 inches / pixels.&nbsp
