Abstract

Natural resource management that does not pay attention to the principles of conservation of natural resources and the environment will have negative implications for environmental sustainability. With the discovery of gold on the coast of Tamiouw Village at this time, residents' activities have shifted to gold mining activities in the coastal area of Tamilouw. This study aims to determine the impact of gold mining on the physical environment in Tamilouw Village, Amahai District, Central Maluku Regency, as well as to determine the impact of gold mining on the social and economic environment of the local community. The research was conducted using non-experimental methods, namely exploratory descriptive, field observations and literature study. The results showed that gold mining carried out in Tamilouw Village uses mercury in the process of separating gold from sand, although there are also some people who carryout traditional processing. What some people are worried about is that the disposal of mercury waste is not carried out according to the required procedures, so that it will have an impact on environmental damage. The existence of mining activities does not affect the social aspects, namely education, health and age and gender; while from the economic aspect, it also contributes to increasing people's income.

Abstract

Analysis of Chromium (Cr) heavy metal content in sediment have been done at inner part of Ambon Bay by using Atomic Absorption Spectrofotometer (AAS). This analysis has been done in six sampling areas, they are : Galala (the first locations), Lateri (the second location), Negeri Lama (the third location), Waeheru (the fourth location), Poka (the fifth location), and Halong (the sixth location). The study aims to determine the content of chromium metal (Cr) in sediments at inner part of Ambon Bay. The analysis showed that the Cr metal content ranged from 33.68-191.74 mg/kg. The chromium (Cr) heavy metal content in sediments is mostly among the quality standards set by the ANZECC (Australian and New Zealand Environment and Conservation Council) in 2000, which is 80-120 mg/Kg

Abstract

The purpose of research it is cycles how knowing cycle trace metals Pb, Cd, Cr and Zn in Callispongia Sp, sediment and water. Techniques of the analysis of trace metals use ICP-OES ((Inductively Coupled Plasma Optical Emission Spectroscopy). Analysis dramatic of the relationship between sponge significant sediment and water show that highest trace metal is Zn to Callispongia sp (6.250 mg/kg dry weight), sediment (0.750 ppm and water 0.790 ppm)

Abstract

Research about bioconcentration of Chrome metal in three types of sponge (Callispongia sp., Xetospongia sp., and Petrosia sp.) from Ambon Bay. This research main is to know the most effective type to accumulate Cr metal in water. The Cr concentration measurement of water, sediment, and sponges at each location shows that metal concentration is 0.001-0.030 ppm in sediment higher than 0.001-0.003 ppm in water. Concentration based on sponges type Callispongia sp., Xetospongia sp., and Petrosia sp. are 0.001-0.262 mg/kg dry weight: 0.001-0.134 mg/kg dry weight, 0.001-0.330 mg/kg dry weight, respectively. The adsorption factor (AF) of Cr metal ranges from 0.000-0.028 ppm. Bioconcentration factor (BCF) based on sponges type Callispongia sp., Xetospongia sp., and Petrosia sp. are -0.011-0.261 mg/kg dry weight, -0.001-0.132 mg/kg dry weight, and -0.001-0.329 mg/kg weight dry, respectively. Sponges type that suitable used as Cr metal pollution monitoring media is Callispongia sp. and Xetospongia sp.
