Abstract

Abstract. In the growth of microorganisms such as fungi, it is necessary to grow a medium that can provide nutrients and as an energy source. Other alternative carbohydrate sources include potatoes, breadfruit, sago, and cassava, which is a distinctive and easy to find food companion. This type of research is descriptive with cross sectional design that aims to determine the difference in alternative media variation from various sources of carbohydrate to Candida albicans. The samples were then made to be the treatment for the creation of alternative media from various carbohydrate sources that further carried out the growth test against Candida albicans. The results of the study are the average growth of colonies on alternative media from Potato carbide sources, namely 655 colonies, breadfruit 1380 colonies, cassava 862 colonies, 372 sago colonies, and semi-synthetic media as a control of 874 colonies. This indicates there is growth of Candida albicans on all alternative media so that it can be used as an alternative medium of fungi growth, as well as the best growth of Candida albicans found in the media Breadfruit Dextrose Agar.

Abstract

Abstract. An inventory of bamboo species in various regions is carried out to explore its potential in the local community so that each type can be utilized and conserved optimally. This study aims to determine the types of bamboo found in Tompobulu Village, the status of kinship between species, and the benefits of bamboo for people's lives. Exploration has been carried out using the tracking method. The species found were identified morphologically on the culm, culm sheath, branches, and leaves. Data were analyzed quantitatively using cluster analysis with UPGMA. PCA was used to determine the role of each morphological character in accession grouping. This study identified eight bamboo species from five genera, namely Bambusa striata, B. vulgaris, Dendrocalamus asper, Gigantochloa atter, Gigantochloa sp., Schizostacyum brachycladum, Schizostacyum sp., and Nastus sp. The kinship dendrogram shows the cluster separation between Nastus and Schizostacyum with Bambusa, Dendrocalamus, and Gigantochloa. All species identified have been used by the community, Gigantochloa atter has the most benefits than other types of bamboo. The results of this study further enrich the biodiversity of bamboo in Indonesia and strengthen the current taxonomic position of bamboo.Keywords: bamboo, bulusaraung mountain, inventory, pangkep, tompobulu village

Abstract

Meningkatnya kejadian resistensi bakteri terhadap antibiotik, mendorong pemanfaatan obat herbal dalam mengobati penyakit infeksi. Daun Acacia auriculiformis diketahui memiliki senyawa metabolit yang dapat menghambat pertumbuhan bakteri Gram positif dan negatif. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri ekstrak daun A. auriculiformis terhadap pertumbuhan bakteri Bacilus sp., Staphylococcus aureus dan Escherichia coli secara in vitro. Penelitian ini dilakukan dengan mengekstrak daun A. auriculiformis menggunakan pelarut etanol. Uji daya hambat ekstrak daun A. auriculiformis dilakukan dengan metode difusi sumur. Adanya aktivitas antibakteri ditunjukkan dengan adanya zona bening di sekitar sumur. Hasil penelitian menunjukkan bahwa ekstrak daun A. auriculiformis memiliki kemampuan menghambat pertumbuhan bakteri Bacillus sp. dan Staphylococcus aureus dengan kategori daya hambat tergolong kuat. Ekstrak daun A. auriculiformis tidak mampu menghambat pertumbuhan bakteri Escherichia coli. Uji golongan senyawa dengan metode skrining fitokimia menunjukkan bahwa daun akasia mengandung senyawa flavonoid dan tanin yang bersifat antibakteri.
