Abstract

This research was conducted to determine the gandaria population and the factors that influence it. The method used was the 10 m X 10 m plot method, with a total of 240 plot plots at 7 different stations based on the presence of gandaria plants. There were 976 trees with a density value of 0.09 ind/m2 or ± 1 individual/11 m2, with a cluster distribution pattern. Factors that affect the gandaria population are the burning of the gandaria population area, land conversion by humans, changes in plant types and factors of increased population growth.

Abstract

Waiheru coastal waters are a coastal area that has diverse ecosystems (mangrove forests, seagrass beds, and other marine biota), so that it has quite high potential for coastal and marine resources (both fish and non-fish). The potential of trevally fish resources in Indonesian waters needs to be known so that it can be developed as an asset in marine tourism activities. The trevally fish is a type of surface (pelagic) fish. This fish is very popular with the community and lives in shallow coastal waters, corals and rocks. The aim of this study was to determine the diversity of trevally fish in the coastal waters of Waeheru, the inner part of Ambon Bay. The research was conducted in August 2013. Sample identification was carried out at UPT Laboratory, Ambon Marine Biota Conservation Center. Observational type research is by making direct observations in the field. Sampling stations consist of 3 stations, repeated 3 times at each station. From the results of the study obtained 11 species of Bubara fish (Carangidae) and 66 individuals. The highest diversity index value was found at station II, namely, 941 and the lowest was found at station III, namely 1,435. The diversity of fish species that is more commonly found is the Caranx Sexfasciatus fish which can be found at each station. The results of water quality measurements in the coastal waters of Waeheru still show a good range for fish life in these waters.

Abstract

Local fruit is one type of natural wealth in Indonesia which has many benefits in the economic sector. Local fruit plants in Indonesia are a fairly large source of income in the agricultural sector to help the community's economy, especially the people of Maluku Province. Uraur Village is one of the villages in Maluku Province. This research aims to determine and explain the community structure and habitat of local fruit-producing trees, including tree types, number of individuals, density, frequency, dominance, importance value index and diversity index. The method used is quantitative descriptive. The environmental parameters measured are soil and air temperature, soil and air humidity, pH and light intensity. The results of this research found 19 types of local fruit plants with 12 families and 12 genera with species diversity belonging to the medium category. Environmental parameters at the research location support the growth of local fruit plants because the habitat at the research location is relatively good. Air temperature ranges from 29-35oC, soil temperature ranges from 28.4-32.16oC, air humidity ranges from 44-68%, soil moisture ranges from 28.4-32.2%, pH 7 and light intensity ranges from 694 -1541 lux.
