Abstract

Indonesia is an archipelago country that is ranked top of the world for its breadth and wealth. More than 75,000 km2 or almost 14% of the world's coral is in Indonesia. The growth of coral reefs in a sea water is strongly influenced by the quality of waters such as chemical oceanographic factors, namely salinity, pH, DO, nitrate and phosphate. The data collection was carried out twice in September and November 2019 in Damas Waters, Trenggalek, East Java. The purpose of this study is to influence the quality of waters on the growth of coral reefs in Damas, Trenggalek, East Java. The sampling method is purposive random sampling that is the determination of the sample with certain considerations. The location points used by 20 stations are spread, namely on artificial reefs, natural coral reefs, open seas and the area around the harbor. Measurements made include in situ water quality with a multiparameter measurement tool, namely AAQ. The results showed the quality of waters in accordance with environmental quality standards with a value of (1) salinity 31.5 - 3.6 (2) pH 7.9 - 8.1 (3) DO> 5 mg / L (4) Nitrate 0.001-0.007 mg / l (5) Phosphate 0.012 - 0.345 mg / L. Correlation value of all components> 0.5 then the relationship of each parameter and coral reef affect each other.

Abstract

The aim of this research is to identify the surface structures of geothermal area in Kawi-Songgoriti based on lineament density and surface manifestation. The lineament density is processed by using satellite image as the input data. The surface structures were analyzed through the density of lineaments on the surface with FFD method. The lineaments are assumed associated with fractures or faults found in geothermal areas those are generally covered by surface manifestation which are hard to be identified. These faults and fractures were assumed as weak line that act as fluid thermal movement, thereby it can be used as guidance for the location of permeable area or a reservoir.  As a result, the high lineament density can be found in Kawi thus assumed as the control of Songgoriti manifestation.

Abstract

Currently the construction of reclamation in Jakarta Bay being carried out on several islands that have been approved by the Government of Indonesia and located nearby the Mangroves forests ecosystem which always inundated by seawater and are affected by tides.  The purpose of this study were analyzing the changes in the mangrove ecosystem area due to the changes in Total Suspended Solid (TSS) based sedimentation and the effect of hydro-oceanography factors on the TSS. This research was conducted using a literature study, processing the LANDSAT OLI images for the analysis of mangrove changes, TSS analysis, and analysis of the effect of hydro-oceanography on TSS within the years of 2013 to 2020. The results of this study indicate that the area of mangrove forest on the coast of North Jakarta is enlarging by 3-5 ha/year, especially in the reclamation island area due to the process of sedimentation which is influenced by hydrooceanography. High sedimentation can be shown from the high value of Total Suspended Solid (TSS) in the waters. The TSS values processed by the satellites images also showed a significant increase during these years between 2013 to 2020 except December 2018 experienced the lowest value. While the hydro-oceanographic factor has lesser effect on the TSS value compare to mangrove ecosystem in the study area.
