Perbandingan Penggunaan Platform Google Classrom dan Grup Whatsapp Dalam Pembelajaran Online Selama Pandemi Covid-19

Dampak dari adanya pandemi COVID-19 pada sistem pendidikan di Indonesia adalah seluruh kegiatan pembelajaran dilaksanakan di rumah masing-masing melalui aplikasi yang tersedia. Pembelajaran online dilakukan melalui berbagai platform seperti google classroom  dan grup whatsapp. Pelaksanaan pembelajaran online perlu menggunakan platform yang mampu menunjang ketecapaian tujuan mata kuliah, untuk itu, perlu diketahui platform mana yang mampu menunjang ketercapaian tujuan mata kuliah sehingga hasil belajar juga baik. Penelitian ini bertujuan untuk membandingkan hasil belajar yang menggunakan platform google classroom dan grup whatsapp dan seberapa efektifnya kedua platform tersebut selama pandemi COVID-19. Jenis penelitian yang dilakukan pada penelitian ini adalah penelitian quasi experiment dengan desain pretest-postest nonequivalent multiple-group design. Populasi dalam penelitian ini adalah seluruh mahasiswa semester 2 yang mengikuti pembelajaran online dengan google classroom dan grup whatsapp. Sampel pada penelitian ini berjumlah 48 mahasiswa yang terbagi menjadi 2 kelompok sesuai perlakuan dengan jumlah masing-masing kelompok 24 mahasiswa. Data hasil belajar mahasiswa diperoleh dari hasil pre test, yaitu nilai Ujian Tengah Semester sebelum dilaksanakan pembelajaran online dan nilai post test, yaitu nilai Ujian Akhir Semester setelah dilaksanakan pembelajaran online pada kedua kelompok perlakuan, data kemudian diolah dengan menggunakan bantuan software Microsoft Excell dan SPSS 25 Hasil penelitian menunjukan bahwa hasil belajar kedua kelas sama sebelum diberi perlakuan dan hasil belajar kedua kelas berbeda setelah diberi perlakuan atau dengan kata lain kelas yang menggunakan platform google classroom  lebih baik dari pada kelas yang menggunakan platform grup whatsapp. Pembelajaran dengan platform google classroom  lebih efektif daripada dengan platform grup whatsapp

PERSEPSI MAHASISWA TERHADAP PRAKTIKUM DARING MATA KULIAH KIMIA ANALISIS

During the COVID-19 pandemic period, every education unit requires an online learning process, not only for theoretical courses, but also for practical courses, including analytical chemistry practicum courses. Student perceptions of online lectures can help students in implementing the process lectures during the Covid 19 pandemic, because a good and correct lecture will help students improve their understanding and knowledge of students. This study aims to find out students perception about online practicum in analytical chemistry. This research is a qualitative descriptive study. The sample was taken using simple random sampling consisted of 45 students. Data were obtained using questionnaires and in-depth interviews.

Perbandingan Aktivitas Ekstrak Daun Tapak Dara (Catharanthus Roseus) dan TBHQ Sebagai Antioksidan Minyak Goreng Terhadap Fotooksidasi UV-C

Cooking oil is one of the sources of human energy with a total consumption of 290 million tons/year by the public. The largest use of cooking oil is the household sector which generally gets its oil from traditional markets. The oil that is traded in the market is often not covered properly so that it is easily exposed to sunlight. The light that hits the oil can cause damage, including the formation of peroxide compounds. Efforts to overcome the damage include adding natural antioxidants as an alternative to synthetic antioxidants. This study aims to determine the impact of 254nm ultraviolet photooxidation on the containment of oil oxidation by the addition of tapak Dara leaf extract and TBHQ. The oil was photo oxidized with variations of 1, 3, 6, and 12 hours to determine the hold. To determine the quality of the oil, three parameters of sample testing were carried out, namely free fatty acid content, peroxide number, and water content. The results of photooxidation showed that cooking oil with tapak Dara leaf extract had lower holding activity than TBHQ. This value was measured on the peroxide number and free fatty acid content, while the measurement of the water content of the measured containment activity was better with a value that met SNI, namely <0.1

Hair Growth Activity Test of Hair Tonic that Contain Combination of Green Tea Leaf Extract and Celery Leaf Extract

Hair loss is an abnormality where the amount of hair is less or more than normal with or without visible thinning. Excessive hair loss can lead to baldness. The prevalence of hair loss in women aged 14-28 years in Jakarta is 50%, and in Surabaya, it occurs in 53.3% of hijab users. One of the formulations that could be used to prevent hair loss is hair tonic formulations. Hair tonic is a cosmetic formulation that functions to stimulate hair growths, both in normal hair and in hair loss and baldness. Hair tonic can be developed from natural ingredients such as green tea leaves, celery leaves, or a combination of both. Green tea leaves contain epigallocatechin-3-gallate and flavonoids which have hair growth activity, while celery leaf (Apium graveolens L.) contain apigenin compounds that have hair growth activity. This research aims to formulation and evaluation of hair tonic contain ethanol extract of green tea leaves (Camellia Sinensis L.), celery leaf (Apium grave lens L.), and a combination of ethanol extract of green tea leaves (Camellia Sinensis L.) and celery leaf (Apium grave lens L.) in guinea pigs. This study is an experimental type of quantitative research with a true experimental design. laboratory and Completely Randomized Design (CRD). Hair tonic formulations were made with 6 formulations given to 6 groups of guinea pigs with a total of 4 guinea pigs in each group. The formulations used were negative control, positive control of celery leaf extract, positive control of green tea leaf extract, formulation of 1 green tea leaf 7,5% and celery leaf extract 2,5%, formulation of 2 green tea leaf 5% and celery leaf extract 5%, formulation 3 green tea leaf extract 2,5% and celery leaf extract 7,5%. Evaluation of hair tonic formulations was carried out by physical evaluation with organoleptic tests and pH tests. Evaluation of hair growths activity observed the hair growth of guinea pigs every 7 days for 28 days and measured it with a caliper. The results of the organoleptic test of organoleptically stable hair tonic formulations were assessed from the color, smell, and texture that did not change. The results of the pH test met the requirements for the skin's pH value of 4.5-6.5. The results of the hair growth test on hair tonic formulations showed that all formulations could grow hair in guinea pigs. Green tea leaves (Camellia sinensis L) extract, celery leaves (Apium grave lens L), and the combination of green tea leaves (Camellia sinensis L) extract and celery leaves (Apium grave lens L) extract can be formulated and used as hair growth in guinea pigs. The best grow hair fast formulation is a combination of green tea leaves extract: celery leaves extract is 2,5%:7,5%

The effects of Eucheuma cottonii on alveolar macrophages and malondialdehyde levels in bronchoalveolar lavage fluid in chronically particulate matter 10 coal dust-exposed rats

Objective(s):To investigate the effect of Eucheuma cottonii on alveolar macrophages (AM) and malondialdehyde (MDA) levels in bronchoalveolar lavage fluids (BALF) in particulate matter 10 (PM10) coal dust-exposed rats. Materials and Methods: Ten groups, including a non exposed group and groups exposed to coal dust at doses of 6.25 (CD6.25), 12.5 (CD12.5), or 25 mg/m3 (CD25) an hour daily for 6 months with or without supplementation of ethanolic extract of E. cottonii at doses of 150 (EC150) or 300 mg/kg BW (EC300). The number of macrophages was determined using a light microscope. MDA levels were measured by TBARS assay. Results: EC150 insignificantly (P > 0.05) reduces the AM in CD groups compared to non treatment groups. EC150 and EC300 significantly (P < 0.05) decreased MDA levels in CD12.5 and CD25 groups relative to non treatment groups. Conclusion: E. cottonii attenuated oxidative stress in chronic exposure of PM10 coal dust
