ANALYSIS OF CADMIUM (Cd), COPPER (Cu), AND LEAD (Pb) CONTENT IN DARAH MUSSEL (Anadara Granosa) ON TIHI-TIHI ISLAND, SOUTH BONTANG DISTRICT, EAST KALIMANTAN.

The waters of Tihi-tihi Island are water areas dominated by fishing boat port activities and traditional scale sea transportation. These dense activities directly or indirectly affect the state of the ecosystem including its benthic biota. Blood clams (Anadara granosa) are one of the marine resources that are widely consumed by the public and easily obtained around the Tihi-tihi island area. The levels of Cadmium (Cd), Copper (Cu), and Lead (Pb) in Blood Clams were analyzed to determine indications of pollution in the Tihi-tihi waters of Bontang City. Sampling was carried out at 4 (four) stations, where each station consisted of 3 sampling points. From 15 shells with a uniform size at each station, acid destruction was carried out and followed by analysis on AAS. The results showed that the levels of Cd in A. granosa ranged 0.357 mg/kg – 1.040 mg/kg, Cu ranged 0.997 mg/kg – 2.066 mg/kg, while Pb ranged 0.800 mg/kg – 1.589 mg/kg. Based on BPOM and SK Health Office RI regarding the quality standards of Cd, Cu, and Pb in food (for clams/bivalves/molluscs) that the measured range of heavy metals is still in the safe category.Keywords : Bioaccumulation, Heavy Metals, Pollutant

Daily Behavior Of Estuary Crocodiles (Crocodylus porosus, Schneider 1801) In The Crocodile Capture, Balikpapan City, East Kalimantan Province

Saltwater crocodile or Crocodylus porosus, is the largest crocodile species in the world. This reptile is not only living in the river as main habitat, but also near the sea, especially at the estuary area. The purpose of this research was to determine the daily behaviour of saltwater crocodiles based on their sex and age. This research was using Continuos Watching Method. The observed variable of behaviour are body movement, feeding, basking, and social in Teritip Crocodile Farm, Balikpapan, East Kalimantan. Chi-Square test showed that the observed object behaviour has differences in activities frequency and population density. In the moving behavior, adult male and teenage crocodiles (both male and female), are more active than female mature crocodiles. In the feeding behavior, hunting has the same way, that is by pouncing abruptly. Differences exist in the way they pounce on prey bodies (at the head, full body, or another body parts), as well as the selection of places to eat food (at land or water surface). In the basking behavior, the differences are seen when they are choosing the sundeck (at land or water surface) and the activities they do while basking (open or close his mouth). In the social behavior, teenage crocodiles are more actively fighting than adult. Meanwhile, adult crocodiles are active in dominance aspects while teenage do not. Specifically, female adult crocodiles are active in vocalizing and keeping the nest, while adult and teenage crocodiles are not

Kualitas Plankton Pada Kolam Pasca Tambang Batu Bara Yang Dimanfaatkan Untuk Budidaya Perairan

Coal post-mining pond has been used for fish cultivation. The success of cultivation in these locations was highly dependent on environmental conditions. The environment as a place for cultivation needs attention for maximum results. One factor that needs to be attention for fish cultivation in post-mining pond is plankton, which acts as an indicator of the quality of waters. Based on identification and calculation was made known that the number of species, abundance, diversity index and uniformity index value of plankton in the post-mining pond was low enough indicated that the water conditions was infertile due to lack of nutrients content, so little of plankton species which were able to live and multiply well
