Abstract

Algae macro is a part of sea plants and  it belongs to lower division plant.  Morphologically, there is no difference between its root, stem, dan leaf.  This plant is known as thallus.  This organism can do photosynthesis, it has clorofil and a simple reproduction  structure.  Ecologically, algae macro is involved in producing oxygen for its habitat and other sea biota.The purpose of this research is to provide information about the presence of varieties of algae macro in the Isenebuai village’s sea shore in the district of Rumberpon and  to look at the ecology, which includes the density, frequency, diversity and uniformity of algae macro.  The method used is the transect line using exploration survey technique.  The result of this research found 30 algae species.  According to the species diversity Shannon-Wiener index, the number is 1,786 or medium whereas species uniformity index, the number is 0,859 approaches 1, so that the uniformity in species is varied.

Abstract

This study aims to examine the physical and chemical conditions of the soil in the rhizosphere of Rhizophora sp. mangroves in East Bintuni Village. The soil samples were collected from two locations, namely, the Rhizopora mangrove around the central market and the mangrove forest on Jalan Nusantara. The results of the laboratory analysis showed that the soil of the Mangrove Mangrove Around the Central Market has a soil texture of 3.75%; dust 54.80%; clay 41.45% so that based on the soil texture triangle by the United States Department of Agriculture (USDA), it belongs to the Silty clay class. The C-organic value of mangrove soil around the market was 5.90% and the archipelago mangrove forests were 5.12% in the very high category. The pH value of the Rhisphere mangrove is 2.95, and the pH value is 3.82, both locations of the pH criteria were very acidic. The Al and Fe values of the RH mangrove are very high (22.86 cmol/kg) and the C-Organic value is very low (39.6 and 41.1, respectively) while the CEC value is medium (18.8 and 41.2, respectively). The results could inform conservation and management practices, helping to preserve and restore mangrove habitats in the region and potentially guiding similar efforts in other coastal areas. In addition, research could examine the long-term effects of these soil conditions on mangrove ecosystems' ability to provide critical ecological services, such as carbon sequestration and coastal protection.

Abstract

Isolation of secondary metabolites from bacteria that have a symbiont with Ascidians has been shown to have enormous potential. This study aims to identify the types of secondary metabolites in Bacillus sp. which has a symbiont with A. gemmata. The research was carried out using laboratory experimental methods by means of phytochemical screening. After testing, the results of the characterization of bacteria that lead to the genus Bacillus and the secondary metabolites contained are alkaloid compounds
