Abstract

Hingga saat ini, beberapa wilayah telah menerapkan kebijakan pembelajaran jarak jauh (PJJ)  secara dalam jaringan (daring) atau diistilahkan dengan PJJ online. Learning management system (LMS) digunakan untuk membuat materi PJJ online berbasis web dan mengelola kegiatan pembelajaran serta hasil-hasilnya sehingga memudahkan peserta didik dalam proses PJJ online kapan pun dan di mana pun. Tujuan penelitian ini adalah mengimplementasikan LMS Edmodo, Google Classroom dan Schoology untuk PJJ online pada mata kuliah Fisika 1 sekaligus membandingkan performanya. Metode penelitian yang digunakan adalah deskriptif kualitatif dan metode Qualitative Weight and Sum (QWS). Fitur-fitur utama yang dievaluasi adalah: (1) Alat komunikasi (dalam bentuk fitur Forum, Chat dan Kelas Sinkron); (2) Fitur materi pembelajaran; (3) Administrasi (dalam bentuk fitur Otorisasi Kelas serta Kehadiran; (4) Tugas online (dalam bentuk fitur Tugas dan Kuis); (5) Penilaian; dan (6) Kolaborasi. Secara keseluruhan, rekapitulasi hasil evaluasi QWS dari ketiga LMS menunjukkan bahwa Schoology mengakomodasi lebih banyak fitur-fitur yang dibutuhkan layaknya sebuah LMS dibandingkan dengan Edmodo dan Google Classroom. Oleh karena itu, jika diurutkan berdasarkan peringkat maka Schoology sebagai peringkat pertama, Google Classroom sebagai peringkat kedua dan Edmodo sebagai peringkat ketiga.

Abstract

The most commonly used method for measuring the density of liquids is based on Archimedes' law. Lubricating oil generally has a defined density standard to show the quality of the oil. The purpose of this study is to determine oil density simply by applying Archimedes' law. This research was conducted in three steps. First, the measurement of the empty pycnometer. Second, the measurement of the pycnometer mass containing distilled water and oil. Third, measurement of copper mass in the medium of air, distilled water and oil. From the results of measurements and calculations, the obtained density of distilled water is (0.995 ± 3,582 x 10-4) gr/cm3 whose value is very close to the value of 1 gr/cm3 so that the distilled water used in this study is suitable as a reference/standard in finding volume copper; oil density is (0.868 ± 2.14 x 10-3) gr/cm3 whose value is very close to the value of oil density measured and calculated with a pycnometer of (0.875 ± 4.637 x 10-4) gr/cm3.

Abstract

COVID-19 virus have affected educational activities to be carried out through e-learning. Discord and Google Jamboard offer advantages in delivering synchronous e-learning. The purpose of this research is to implement e-learning of Physics 1 course using Discord integrated with Google Jamboard and Powerpoint. In this research, we used qualitative-descriptive method which conducted in several steps, i.e: (1) Discord installation and Physics 1 Class preparation; (2) Virtual Tablet Server installation and its testing for mobile phone; (3) Learning materials preparation in Powerpoint; (4) Implementation of Physics 1 Class using Discord integrated with Google Jamboard and Powerpoint; (5) Evaluation of the results and (6) Surveying of student’s opinion about e-learning using using Discord integrated with Google Jamboard and Powerpoint. Discord can be used as an alternative e-learning tool because of its practical use as well as more powerful when integrated with Google Jamboard and Powerpoint, especially for mathematical-analytics subject such as Physics. This is supported by the results of a survey in which 34 out of 39 students said they wanted to use Discord and Google Jamboard for other mathematical-analytics subjects.

Abstract

Tujuan penelitian ini untuk merancang dan mengimplementasikan prototype sistem otomatisasi pada sel electrolyzer sehingga dapat diperkirakan pengaturan tegangan, waktu alir arus listrik dan konsentrasi cairan elektrolit yang optimal dalam menghasilkan gas Brown. Perangkat keras yang digunakan adalah sel electrolyzer tipe wet cell, bubbler dan rangkaian elektronika sistem otomatisasi. Komponen-komponen rangkaian elektronika sistem otomatisasi yang digunakan yaitu Arduino Nano R3, sensor suhu DS18B20, sensor suhu DHT11, LCD, buzzer, relay, power supply adjuster, kipas, konektor dan LED. Sel electrolyzer dapat berfungsi dalam menghasilkan gas Brown baik pada tegangan 5V, 10 dan 15 V serta pada konsentrasi elektrolit 1% dan 5%. Kemudian, sistem otomasi memberikan perkiraan kinerja optimal sel electrolyzer pada tegangan 15V, konsentrasi cairan elektrolit 5% dan waktu alir arus listrik sebesar 1,5 detik. Setelah mencapai kondisi tersebut, maka sel electrolyzer mulai bekerja lagi setelah suhu sudah turun kurang dari 50 OC.
