Publisher : PT. Marosk Zada Cemerlang

Penelitian ini memiliki tujuan untuk mengetahui tingkat efektivitas pembelajaran daring mata kuliah fisika di perguruan tinggi. Penelitian ini merupakan penelitian studi literatur dengan mengambil referensi dari beberapa jurnal dan sumber pustaka dengan pemaparan secara naratif untuk melihat efektifitas pembelajaran daring di perguruan tinggi. Sebagai pendidik, dosen memanfaatkan berbagai media pembelajaran dan aplikasi digital yang diharapkan dapat terintegrasi pada pengalaman belajar mahasiswa dan tetap mengacu pada capaian pembelajaran dalam rencana pembelajaran semester (RPS). Fisika merupakan salah satu mata kuliah wajib. Pembelajaran daring pada mata kuliah fisika di perguruan tinggi memang cukup baik, namun memiliki kendala terhadap pemahaman terhadap materi fisika yang diajarkan oleh dosen di antaranya pembelajaran yang diberikan lebih dominan teoritis dan kegiatan praktikum tidak optimal dilaksanakan. Sehingga efektivitas pembelajaran daring mata kuliah fisika di perguruan tinggi dapat dikategorikan cukup efektif karena hasilnya tidak optimal.

Publisher : Universitas Negeri Medan

Penelitian ini bertujuan untuk menentukan penyebaran batuan dan fluida yang terdapat di bawah permukaan daerah potensi panas bumi di desa Huta Baru kecamatan Sipirok kabupaten Tapanuli Selatan berdasarkan analisa nilai resistivitas. Penelitian dilakukan dengan menggunakan metode geolistrik schlumberger, didasari dengan hukum Ohm untuk mengetahui nilai resistivitas jenis perlapisan batuan pada tiap lapisan permukaan bumi. Dengan menginjeksikan arus melalui dua elektroda arus maka beda potensial yang muncul dapat terukur dari elektroda potensial. Data pengukuran di lapangan berupa beda potensial dan arus dapat digunakan untuk menghitung harga resistivitas semu (Apprent Resistivity) yang diperoleh dengan alat geolistrik (Resistivity meter), ARES-G4 v4.7 SN: 0609135 (Autematic Resistivity System). Kemudian data yang diperoleh dibuat gambar model penampang dua dimensi dengan menggunakan software Res2Dinv untuk menampilkan penampang kontur nilai resistivitas perlapisan batuan. Hasil penelitian geolistrik menunjukkan bahwa daerah penelitian memiliki nilai resistivitas yang berbeda-beda yang berkisar antara 4,72 m hingga 167 m. Pola penyebaran fluida geothermal pada daerah penelitian tersebar secara lateral, dimana lapisan pasiran sebagai zona konduktif dan lapisan tanah lanauan sebagai lapisan penutupnya.
