Abstract

Regeneration of Imperata grassland areas is becoming increasingly important, both to create new secondary forest and to recover the original biodiversity. We studied the diversity of plant communities in secondary succession of Imperata grasslands using 45 subplots of 9 linear transects (10 m x 100 m). Data was collected and all stems over 10 cm dbh were identified  , the Importance Values Index (IVI) for all trees were calculated, saplings and seedlings were counted  and analysed, and soil samples were taken and analysed. Results showed that  after more than 10 years of regeneration, 65 families were encountered consisting of 164 species, which were dominated by Vernonia arborea Buch.-Ham, Vitex pinnata L., Macaranga gigantea (Reichb.f. & Zoll.) Muell.Arg., Symplocos crassipes C.B. Clarke, Artocarpus odoratissimus Miq., and Bridelia glauca Blume. The effects of regeneration, from Imperata grassland to secondary forest, on soil were the strongest in the A-horizon where an increase in carbon, N content, and pH were observed. Our result shows that Imperata grasslands appear to be permanent because of frequent fires and human interferences and so far few efforts have been made to promote sustainable rehabilitation. If protected from fire and other disturbances, such as shifting cultivation, Imperata grassland will grow and develop into secondary forest.

Abstract

Background: Yellow wood (Coscinium fenestratum) is one of the typical forest plants of East Kalimantan. The hallmark of this plant is the roots, stems and the fruits pulp have a yellow color. There have been many studies on its use and potential in treating liver disease. However, there is limited research about the use of their fruits peel. Objectives: The purpose of this study was as an initial screening of the antioxidant and antibacterial activity from yellow wood (Coscinium fenestratum) fruits peel. Material and Methods: The yellow wood fruits peel was extracted using methanol solvent to obtain the MeOH extract of their fruits peel. The DPPH test was carried out to determined its antioxidant activity (25,50 and 100 ppm). The agar well difusion method was carried out to determined its antibacterial activity. Phytochemical tests are also carried out to determined the secondary metabolites of that fruits peel. Results: The results of the phytochemical test showed that the fruits peel contained alkaloids, flavonoids, carbohydrates, and tannins, but there were no terpenoids or steroids. The fruits peel has an antioxidant activity (58%) at 100 ppm concentration. While the antibacterial test showed strong inhibition at 100 ppm concentration on S. mutans, S. aureus, P. acne and E. coli bacteria. Conclusions: The fruits peel of the yellow wood has compounds that have strong antibacterial activity and medium antioxidant activity.

Abstract

Background: Contemporary’s trend in education indoensian has shifted orientation of madrasah, caused disapperance its humanistic-religious character, neglecting of spiritual aspect in practice. On the contrary, empirical-pragmatice inhibited madrasah to adapt with contempoary education dynamics, such a charactes by al-Ghazali, who stated that ultimate reality can not gained by rational-empiric without involving  spiritual intuition. Porpuse of the study:  This study proposes a unique framework for integrating Al-Ghazali’s epistemology into madrasah education, aiming to harmonize divine revelation, reason, and spiritual intuition in shaping contemporary educational practices. Method: This study employed a library research method using secondary sources, such as scientific texts, journal articles, and classical books, with in-depth information gathering to identify impact of the relationship between scriptural revelation (naql), reason(aql), and intuition in Al-Ghazali’s thought. Result: Al-Ghazali posited that reason(aql) and empirical experience are insufficient for realization of the ultimate truth without the incorporation of spiritual experience (irfani), gained through creation enviroment namely riyadhah (spiritual training), al-Ghazali stated character was a soul spontaneity, Conclusion:  thus, it can be concluded that the reconstruction of the madrasah's epistemology has a potential to harmonize the dimensions of scriptural revelation (naql), reason (aql), and intuition (irfani). it is crucial for madrasahs to adapt to contemporary era while maintaining their identity as formal Islamic education through a holistic approach, ensuring that students are intellectually competent as well as morally and spiritually grounded.
