Exploration is a mini form of research. The results of mini research can be used as teaching material. Exploratory activities will make a person more active and thorough. The aim of this research is to inventory the plants in the forest of Pontianak Digulis Park and conduct a literature study on the benefits of the plants found. Sampling was carried out observationally, and the type of research was descriptive. This research consists of two stages. The first stage of research includes identification using books of key determinations and benefits of plants found using literature studies. The second stage of research is analyzing its potential as teaching material or learning resource in the Megabiodiversity course. The research data was then documented and analyzed qualitatively. The results of the research found that there were 19 types of plants at the research location, namely durian, cengkodok, prawn pinch, banyan tree, orchid, bird's nest fern, mahogany, Bintangor, mangosteen, fern, banana tree, jampang, white teak, kekopian, hanjuang, red shoots, taro , fruit loh and laban. This type of plant has been widely studied and has a role. The role of the plants used indicates that the results of this research can be used as a learning resource in the Tropical Megabiodiversity course.

Antibiotic resistance is a global problem in the health sector. The level of antibiotic resistance that occurs can be caused by several influencing factors, including 6 isolates of rhizosphere bacteria that were successfully isolated from the rhizosphere of the Avicenia marina plant. The purpose of this study was to isolate and determine the best minimum inhibitory concentration of rhizosphere bacteria of the A. marina plant and its effectiveness in inhibiting pathogenic bacteria S. aureus. This study is a quantitative research method using the isolation and characterization of rhizosphere bacteria, antagonistic test of rhizosphere bacteria and test of the results of the extraction of filtrate of rhizosphere bacteria culture of A. marina plants. The results of this study were (1) five of the isolates of bacteria that were successfully isolated were included in the Bacilus type and 1 isolate of bacteria included in the Cocobasil type; (2) there were 3 of the 6 isolates that could inhibit the growth of pathogenic bacteria S. aureus with an inhibition range of 10.04-4.42 mm; (3) Rhizosphere bacterial isolate (TN 1) is an isolate with the best inhibition diameter and is categorized as strong, namely 10.04 mm; (4) ethyl acetate extract of Rhizosphere bacterial isolate culture filtrate (TN 1), has a minimum inhibitory concentration of 0.50% against pathogenic bacteria S.aureus with an inhibition diameter of 7.18 mm which is better when compared to the positive control using chloramphenicol.

This study aims to determine the diversity of sponge symbiont bacteria and the effectiveness of active compounds of bacteria that are symbiotic with marine sponges from Lemukutan Island waters. The methods in this study are isolation of sponge symbiont bacteria, characterization of sponge symbiont bacteria, antagonistic tests, activity tests of the best sponge symbiont bacterial isolate extract culture filtrate, and GCMS/MS tests. The results showed that nineteen isolates of sponge symbiont bacteria were successfully isolated from sponge types from Theonella cylindrica and Hyattella intestinalis sponges in Lemukutan waters. Seven isolates of sponge symbiont bacteria are included in the Gram-positive bacteria genre. While the other twelve are included in Gram-negative bacteria. Ten of the nineteen isolates of sponge symbiont bacteria have antibacterial activity for S. aureus. Isolate Sp4 10-6 B, based on the results of antagonistic tests, has an inhibition diameter of 10.28 mm, which is categorized as solid inhibition. Ethyl acetate extract of Sp4 10-6 culture filtrate has a minimum inhibitory concentration value of 0.5% against pathogenic bacteria S.aureus. The active compound with the potential for antibiotic development is the Tetradecane compound, which has the highest peak area of the eight other types of compounds. This shows that the concentration of the compound contained is higher than the other compounds. This compound is included in the aliphatic hydrocarbon and alkane groups.
