Abstract

Coral reefs are one of the important ecosystems that need data inventory in order to manage marine resources both spatially and temporally. Remote sensing with drone technology is one of the vehicles for collecting data related to coral reef ecosystems in real time. Along with the times, drones are widely used in research both in terrestrial and in coastal areas. This research was conducted on December 4 – 10, 2018 in the Karang Lebar, Seribu Islands, Jakarta. The purpose of this research was to explored the ability of drones as a vehicle to complement field survey data for coral reef mapping. In addition, conducting a pixel-based analysis for coral reef classification based on WorldView-2 satellite imagery using field survey data and additional data from drone data. Based on the results of the study, information was obtained that drone imagery can help visual interpretation in detecting coral reefs. Thus, field survey data that are not covered in the research area can be assisted by the use of drones as a complementary vehicle for field survey data. The coral reef classification process using WorldView-2 imagery can be mapped well. Drone imagery has proven to be an alternative in field data collection as a training area in identifying coral reef objects, such as with massive coral lifeforms that can be clearly seen from drone images. It's just that visual interpretation is limited because of the water column, making it difficult to identify objects.

Abstract

The large potential of marine fisheries owned by the City of Bengkulu can be an economic source for the local community. The fish potential comes from pelagic fish and reef fish. One of the reef fish is the parrot fish (Scaridae). Parrot fish in Bengkulu City are obtained from Tikus Island which are sold on Malabero Beach. The purpose of this study was to analyze the ecobiological aspects of parrot fish (Scaridae) in Tikus Island waters, Bengkulu City. The results of this study are expected to provide information in the form of valid data regarding the ecobiological aspects of parrot fish (Scaridae) in Tikus Island waters, Bengkulu City. In this study, data collection to look at ecological or environmental aspects was carried out by direct observation in the field at 3 stations, while biological aspects, namely food habits (amount/type of food), were observed through a microscope in the laboratory. The results of water parameter measurements, namely the temperature at station 1 ranged from 28-29 0C, station 2 is 29 0C, station 3 is 29 0C. pH value at station 1 is 7.0-7.3, station 2 is 7.3-7.7, station 3 is 6.5-7.1. Salinity values at station 1 is 31 ppt, station 2 is 30 ppt and station 3 is 31 ppt. Dissolved oxygen (DO) at station 1 ranged from 5.6-6.3 mg/L, station 2 5.2-5.3 mg/L and station 3 5.6-6.1 mg/L. The water brightness at station 1 is 9.2 m, at station 2 is 6.6 m and at station 3 is 7.4 m. Current velocity at station 1 ranges from 0.09-0.11 m/s, station 2 are 0.08-0.14 m/s, and at station 3 ranges from 0.05-0.09 m/s. Water depth at station 1 is 9.2 m, station 2 is 7.3 and station 3 is 7.5 m. These results indicate that Tikus Island water have a good environment for survival and habitat of parrot fish (Scaridae) or other marine biota. Furthermore, the biological aspects studied are food habits. Based on the identification results, 4 groups of food types were found in the parrot fish stomach, namely phytoplankton, zooplankton, sand coral, and were not identified. The percentage of food groups found from phytoplankton, zooplankton, sand coral, and not identified were 53%, 3%, 15%, 29%, respectively.
