Abstract

Telah dilakukan uji perlindungan terhadap sinar UV oleh senyawa hasil fraksinasi ekstrak metanol semipolar kulit buah G. mangostana Linn secara in vitro dengan menggunakan alat spektrofotometer UV-Visibel. Uji perlindungan terhadap sinar UV dilakukan berdasarkan metode Mansur dengan mengukur serapan larutan uji dalam pelarut etanol pada konsentrasi 20 mg/100 ml pada panjang gelombang 290 sampai 320 nm. Hasil pengujian secara in vitro menunjukkan bahwa fraksi n-heksan memiliki kemampuan perlindungan UV sedang ; SPF (Sun Protection Factor) 15,02 ± 0,01, fraksi diklorometan dan  butanol memiliki kemampuan perlindungan UV ultra.dengan SPF masing-masingnya adalah 67,62 ± 1,68 dan 61,12 ± 0,24. Hasil penelitian menunjukkan fraksi diklormetan memiliki potensi proteksi terhadap sinar UV paling baik dibanding kedua fraksi yang lain.tify>  Key word : Garcinia mangostana, tyle=mso-bidi-font-style:normal>urkumin dan analognya, SPRMs, docking, reseptor  progesteron IA28 -language:IN>Antiradikal, DPPH, IC50, fenolik total, Elephantopus schaber L., Ocimum basilicum L.forma citratum Back., Graptophylum pictum Griff, Gynura procumbens Merr.

Abstract

Teaching and learning activities take place both in either a classroom with a lecturer or outside of classroom such as at home and library to achieving educational goals. In the process of teaching and learning in the campus lecturers are required to perform optimally the curriculum that has been set in the form of syllabus. One of the components contained in the syllabus is teaching methods as well as the means and resources of the lessons that will be given to the students, who have an important role in implementing the learning process to achieve the set goals. Library has an important role in supporting the learning materials required by students and support the smooth teaching and learning process so that the goals set can be achieved. The attainment of this goal for the personal development of students educates themselves on an ongoing basis to solve problems and enhance social attitudes. The existence of UPT Library at the University of Muhammadiyah Bengkulu is very important because teaching and learning activities are generally limited and incomplete and often is a new supporter for the development of student lessons. So clearly the essence of UPT UMB library is the center of learning resources and information sources. From the observation, many students of Muhammadiyah University of Bengkulu were still very rarely visit the library, and they had lack of interest in reading. Based on these problems, the writer was interested in raising the title "Intensity of Library Exposure to Students Learning Outcomes (Case Study of Muhammadiyah University of Bengkulu). The formulation of the problem was how the Intensity Relationship Utilization UPT Library University of Muhammadiyah Bengkulu and how the results of student learning University of Muhammadiyah Bengkulu. The purpose of this study to determine the relationship of Intensity Utilization of UPT Library University of Muhammadiyah Bengkulu and to know the results of student learning University of Muhammadiyah Bengkulu

Abstract

In this study a High Performance Liquid Chromatography (HPLC) has been used for determination of rubraxanton on bark extracts Garcinia spp (Garcinia mangostana, Garcinia Cowa, Garcinia griffitii, Garcinia dioica and Garcinia forbesii). HPLC system consisted of C-18 reversed phase column with a length of 250 mm, diameter 4.6 mm, 20 mL injection volume, mobile phase methanol: water (gradient system with polarity) and flow rate of 1ml/min. Rubraxanton levels obtained in this study; 9.161% for G.mangostana, 6.942% for G.cowa, 6.762% for G.dioica, 0.499% for G.forbesii and 0.229% for G.griffitii. The method has been validated for specificity, linearity, accuracy, precision, limits of detection (LOD) and limits of quantitation (LOQ). The linearity of the method can be seen from the regression coefficient r=0.9996 with a linearity range from 1.72 to 55 ug/ml. Recovery of rubraxanton in the extract of G.mangostana was between 99.61 to 101.08%. Intra and inter day precision showed relatively small level of standard deviation (lower than 2%). Limit Of Detection (LOD) and Limit Of Quantitation (LOQ) are 0.55 ug/ml and 1.82 ug/ml respectively.Keywords : rubraxanton, bark extracts, Garcinia spp.

Abstract

The Covid-19 pandemic has brought a huge change to today's life. The rapid spread of the process made the government make various efforts to overcome this. One of them is by limiting activities, namely learning activities boldly (school from home). Courageous learning activities make students learn from home. However, in practice many parents and students complain that they are not interested in doing these learning activities. This study aims to determine the impact of distance learning activities (school from home) on the stress of middle and high school students in West Sumatra. The measuring instrument of this research is the Perceived Stress Scale (PSS) by Cohen. The results showed that most junior and senior high school students experienced stress in the moderate category. This is sufficient to indicate that the subject feels that his current life is stressful. Regarding the feelings of subjects with COVID-19, most of the subjects felt worried (26%), afraid (17%), and felt shocked (14%). At the beginning of the pandemic, as many as 94.7% of students felt that the covid-19 virus was dangerous and only 5.3% felt it was harmless. Keywords: Stress, Covid-19, teenager Pandemi Covid-19 memberikan perubahan besar terhadap kehidupan saat ini. Cepatnya proses penyebaran membuat pemerintah melakukan berbagai upaya untuk mengatasi hal tersebut. Salah satunya dengan membatasi kegiatan, yaitu kegiatan belajar secara daring (school from home). Kegiatan pembelajaran daring membuat siswa belajar dari rumah. Namun, pada prakteknya banyak orangtua dan siswa yang mengeluhkan bahwa mereka merasa tidak termotivasi dalam melakukan kegiatan pembelajaran tersebut. Penelitian ini bertujuan untuk mengetahui dampak kegiatan pembelajaran jarak jauh (school from home) terhadap stress siswa SMP dan SMA di Sumatera Barat. Alat ukur penelitian ini menggunakan skala Perceived Stress Scale (PSS) oleh Cohen. Hasil penelitian menunjukkan bahwa sebagian besar siswa SMP dan SMA mengalami stress pada kategori sedang. Hal ini mengindikasikan bahwa subjek merasa kehidupannya saat ini cukup membuat stress. Terkait dengan perasaan subjek dengan covid-19, sebagian besar subjek merasa merasa cemas (26%), takut (17%), dan merasa kaget (14%). Saat awal pandemi, sebanyak 94,7% siswa merasa bahwa virus covid-19 ini berbahaya dan hanya 5,3% yang merasa tidak berbahaya.Kata Kunci: Stress, Covid-19, Remaja
