Abstract

The Semambu rattan (Calamus scipionum Lour) plant contains phenolic compounds, such as flavonoids and polyphenols that have the ability as antioxidants. Therefore, the community often consumes C scipionum Lour, and the stiff stems are made of crafts. However, the skin, the content of which is not scientifically known, is currently considered a waste in the community. This study was conducted to determine the results of phytochemical tests and the activity of methanol extract of young bark of the Semambu rattan plant (C. scipionum Lour). The bark of young Semambu rattan stems is extracted by maceration, and then the extract obtained is carried out by phytochemical screening. Antioxidant acrypability was measured using the DPPH method at a wavelength of 517nm. The results of phytochemical testing of young bark extract of C. scipionum Lour contain flavonoids, saponins, tannins, alkaloids and terpenoids. The research results on antioxidant young stem bark C. scipionum Lour with positive control in the form of ascorbic acid obtained results IC50 = 65.10 ppm, which is classified as a potent antioxidant. The conclusion of this study is that the extract of the young bark of Semambu rattan (C. scipionum Lour) can be used as an alternative antioxidant.

Abstract

The development of globalization in the previously traditional economic sector has shifted towards digitalization, affecting the high use of the Shopee application by Jambi University PPKn students. This phenomenon has resulted in consumptive behavior that is not in harmony with the values of Pancasila. This study aims to determine the impact of the intensity of using the Shopee application on student consumptive behavior, by considering the Pancasila perspective. A quantitative approach was used in this study through survey methods, involving 39 respondents. Data analysis using SPSS Version 26 shows that the intensity of using the Shopee application significantly affects the consumptive behavior of Jambi University PPKn students, with a p-value of < alpha (0.000 < 0.05). The effect reached 54.3%, while other influencing factors were not studied in this study.

Abstract

Indonesia merupakan negara tropis yang selalu disinari matahari sepanjang tahun. Sinar matahari dapat berdampak buruk bagi kesehatan kulit karena mengandung sinar ultra violet. Oleh karena itu, penting untuk mencegah efek buruk paparan sinar matahari dengan menghindari paparan yang berlebihan dengan menggunakan tabir surya. Penelitian ini bertujuan untuk mengetahui potensi tabir surya pada tanaman daun senduduk (Melastoma malabathricum L.). Penelitian ini dilakukan dengan menggunakan spektrofotometer UV-Vis untuk penentuan nilai SPF. Hasil ekstrak etanol daun senduduk positif mengandung alkaloid, flavanoid, saponin, steroid, dan tanin. Nilai SPF yang dihasilkan dari ekstrak etanol daun senduduk konsentrasi 100 ; 400 ; dan 700 ppm menghasilkan nilai SPF sebesar 17,28 ; 31,4 ; dan 40 yang dikategorikan sebagai proteksi ultra.

Abstract

Penelitian ini bertujuan untuk menganalisis Profil Pelajar Pancasila dengan berlandaskan kearifan lokal Suku Anak Dalam (SAD) Jambi. Metode penelitian ini adalah kualitatif deskriptif. Adapun subjek dalam penelitian ini ialah para Tumenggung, Mengku dan masyarakat SAD Jambi. Untuk teknik  pengumpulan  data  yang digunakan  dalam penelitian  ini  yaitu  melalui  pengamatan (observasi), wawancara, studi literatur, dan studi dokumentasi kemudian dianalisis untuk menjelaskan Profil Pelajar Pancasila yang berbasis kearifan lokal SAD Jambi. Temuan penelitian menunjukkan bahwa keenam dimensi termasuk elemen kunci dari Profil Pelajar Pancasila telah terimplementasikan dengan baik melalui kearifan lokal dalam kehidupan masyarakat SAD Jambi secara turun-temurun. Temuan ini menekankan pentingnya pengkajian kearifan lokal khususnya pada SAD Jambi sebagai salah satu wujud pelestarian. Profil Pelajar Pancasila ditetapkan oleh Kemendikbudristek diajarkan pada pendidikan formal saja. SAD Jambi, yang mayoritas anggotanya tidak mendapatkan akses ke pendidikan formal, tidak sepenuhnya memahami keenam dimensi Profil Pelajar Pancasila tersebut. Namun, adat istiadat, kebiasaan, dan tradisi yang dimiliki oleh masyarakat SAD Jambi telah menerapkan setiap dimensi Profil Pelajar Pancasila dalam kehidupan sehari-hari mereka secara turun-temurun. Penelitian ini dapat membantu mengintegrasikan kearifan lokal SAD ke dalam kurikulum pendidikan formal dan non-formal.

Abstract

The SARS-CoV-2 virus is the infectious agent that causes COVID-19, a feverish condition brought on by inflammation in the infected patient’s body. Sungkai leaf (Peronema canescens Jack) is one of the Indonesian people who rely on herbal remedies to treat COVID-19. This study aims to determine how much flavonoids are present in ethanol, ethyl acetate, and n-hexane extracts, as well as the anti-inflammatory properties of ethanol extract, ethanol fraction, and n-hexane fraction of Sungkai leaves. The procedure was performed in-vitro with a UV-Visible spectrophotometer by observing the absorption response to inhibition of denaturation of inflammatory protein. The inhibition value was then computed via linear regression, and the IC50 and IC70 values were ascertained afterward. The ethanol fraction, ethanol extract, and n-hexane fraction in this investigation had the best inhibition values (%) at a concentration of 15 ppm, corresponding to 74.27%, 54.48%, and 18.52%. The sungkai leaves ethanol fraction > n-hexane fraction > ethanol extract had the best IC50 and IC70 values. Comparatively, the ethanol extract contained the largest amounts of flavonoids, 38.782 μg/mL.

Abstract

Sungkai (Peronema canescens Jack) is a plant that has phenolic content as an antioxidant that can enhance the immune system (immunomodulator). This study aimed to determine the phenolic content and antioxidant activity of Sungkai leaves (Peronema canescens Jack). The method  of antioxidant with invitro using of the DPPH where the ability of a compound to inhibit DPPH radicals is calculated from the absorbance value using UV-Vis spectroscopy. And Determination of total phenolic content was carried out using UV VIS spectroscopy at a wavelength of 745 nm with the help of Folin Ciocalteu reagentand a nd gallic acid standard curve . The test results showed that the water and ethanol extracts with a concentration of 0.1% had a phenolic content of 0.002% and 0.007%, their antioxidant activity (IC50) with a concentration of 0.02; 0.04; 0.06; 0.08; and 0.1% in the water and ethanol extracts of Sungkai leaves have values of 0.025% and 0.03% respectively. Therefore the best antioxidant activity (IC50) was extracts ethanol of sungkai leaves with phenolic content  of 0.007% and IC50  of 0.03%.

Abstract

Areca catechu L. has been widely used as a traditional medicine in medicinal practices in various countries around the world. Areca nut contains secondary metabolite compounds such as alkaloids, flavonoids, triterpenoids, steroids, and tannins so it has great potential to be developed as a medicine. The use of anti-inflammatory drugs from natural ingredients is widely developed because synthetic non-steroidal anti-inflammatory drugs cause side effects to the body such as nausea, diarrhea, headaches, and stomach ulcers. This study aims to determine the content of secondary metabolites and determine the anti-inflammatory activity of ethanol extracts of young and old areca nut seeds. Old areca nut seeds used are areca nut fruits that have an orange color while young areca nut seeds are areca nut fruits that have a green color. The anti-inflammatory activity test method was carried out using the protein denaturation inhibition method at 5, 10, 15, and 20 ppm extract concentrations. The results of this study indicate that young and old areca nut seeds positively contain alkaloids, flavonoids, tannins, and saponins and negatively contain steroids. The results of anti-inflammatory activity testing show that ethanol extracts of young and old areca nut seeds have the potential as anti-inflammatory because they have a percentage value of protein denaturation inhibition greater than 20%. A comparison of anti-inflammatory activity between areca nut seeds can be seen from the IC50 value of ethanol extract. The IC50 results show that young areca seeds have an IC50 value of 7.42 ppm which is higher than the old areca seeds of 11.52 ppm
