Abstract

Metode mengajar sangat berperan dalam proses belajar mengajar, apapun pendekatan dan model yang digunakandalam mengajar , maka harus didukung oleh metode mengajar. Dalam kegiatan mengajar makin tepat metode yangdigunakan, maka makin efektif dan efesien kegiatan pembelajaran yang pada akhirnya akan menunjang danmengantarkan keberhasilan belajar mengajar yang dilakukan oleh guru atau dosen. Metode dalam mengajar berperansebagai alat untuk menciptakan proses mengajar dan belajar. Telah dilakukan penelitian terhadap penerapan metodepenugasan dan tanya jawab dalam mengajar konsep sifat koligatif larutan. Tujuan dari penelitian adalah untukmengetahui: ada tidaknya perbedaan hasil belajar Mahasiswa pada konsep sifat koligatif larutan yang diajarkandengan metode penugasan dan metode tanya jawab. Dengan penerapan metode tersebut diharapkan dapat diketahuimetode yang mana terjadi peningkatan hasil belajar mahasiswa. Uji t digunakan untuk membandingkan hasil belajarMahasiswa yang diajarkan dengan metode Penugasan dan metode tanya jawab, Hasil analisis data hasil ujianmahasiswa diperoleh thitung sebesar 0,276 dan ttabel pada α 0,05 sebesar 2,021, karena thitung lebih kecil dari ttabelmaka Ho diterima dan Ha ditolak sehingga dapat disimpulkan, tidak terdapat perbedaan hasil belajar mahasiswa untukmata kuliah kimia dasar yang diajarkan dengan menggunakan metode penugasan dan metode tanya jawab.

Abstract

Most of the materials in chemical bond are abstract concepts such as ions, ionic radii and orbital. Concepts are considerably difficult to be studied by students who have not had formal thinking ability. This difficulty may be caused error concept, namely the concept of student understanding is different from the agreement by experts. One source of error is the concept of the textbooks used in the learning process. Inproper emplanation or inadequate chemical bonds in the material in the books or high school chemistry teaching materials can lead to errors in sudent. The remedial concept using materials that have been corrected his mistakes and shortcomings plus can reduce errors that occur in students' concept.

Abstract

Corona virus disease/COVID-19 is an acute respiratory infection caused by SARS-CoV-2 and has become a pandemic. COVID-19 can be prevented by efforts such as physical distancing, washing hands, using masks and self-isolation as well as regional isolation. Moringa is a plant that can be used both as food and medicine. The purpose of this study was to observe the activity of Moringa leaf compounds in inhibiting Mpro (main protease) SARS-CoV-2. Moringa leaf compounds tested were Gamma tocopherol, Benzyl glucosinolate and Chlorogenic acid. The compound was taken from pubchem, while Mpro SARS-CoV-2 (receptor) was obtained from the world protein bank with the PDB code 6W63. This research was conducted using the In Silico method and AutoDock Vina software was used for the tethering process. The results of gridbox optimization by re-tethering control ligands obtained RMSD results of 0.122 . The results showed free energy Gibbs (ΔG) Gamma tocopherol (-6.8 kcal/mol), Benzyl glucosinolat (-6.6 kcal/mol), and Chlorogenic acid (-7.0 kcal/mol) which indicated a stable inhibitory reaction of Moringa leaf compounds against Mpro SARS-CoV-2. Based on Lipinski's rules, the compounds from Moringa leaves tested were qualified to be used as herbal medicines to be used orally.

Abstract

Ablution is a ritual activity that is quite important in the implementation of prayer. The amount of waste water produced by Ablution activities is large and the reserves are abundant. It is estimated that in one month a mosque with 4325 visitors per week who performs ablution produces 86.5 m3/person/month of ablution waste. This potential waste can be used for various purposes such as watering plants, or aquaculture, and as a pico hydro power plant. The Pico hydro power plant is a term used for hydroelectric power generation capacities below 5 KVA or even smaller, ranging from 200-300 VA. Pico hydro can be generated from a turbine, which is rotated by the natural water flow at a minimum of one meter inclination, the power generated is not too large and is suitable for simple electrical equipment. Ablution waste has the potential to be developed as a pico hydro power plant.
