Abstract

Scylla spp. live in association with the mangrove forest. A damaged or loss of mangrove forest ecosystems will affect the mangrove crab population. This research aims to determine the types, morphometry and characteristics of mangrove crabs in the mangrove forest of Mutusan Estuary, Sambas Regency. The research was carried out from April to June 2015. The research obtained two species i.e., S. paramamosain and S. serrata. The species S. paramamosain has an average weight (W) of 138.13 g with an average carapace width (CW) of 95.42 mm, an average frontal margin width (FMW) of 27.97 mm and an average chela length (CL) of 57.45 mm. The species S. serrata has an average weight (W) of 212.82 g with a carapace width (CW) of 205.14 mm, an average frontal margin width (FMW) of 28.42 mm and an average length of chela (CL) of 67.11 mm. Based on the size of carapace width (CW), the Scyla spp. of young phase dominates the mangrove crab population in the mangrove forests of Mutusan Estuary, Sambas Regency.

Abstract

The use of polyoethylene degradable polyethylene in Indonesia, especially in West Kalimantan, is high enough to potentially cause environmental pollution. One way to resolve pollution caused by polyethylene oxo-degradable plastic waste is to utilize isolates from the peat soil around the Kuala Dua Final Disposal Site, Rasau Jaya, which is able to degrade oxo-degradable polyethylene. This research aims to determine the bacterial genera that can to be expected to degrade Oxo-Degradable Polyethylene. Samples were taken from peat soil with the incubation method of oxo-degradable polyethylene for 2 weeks, 4 weeks and 6 weeks. Isolation use the pour plate method with Enrichment Broth Media and Enrichment Agar Media. The isolation results obtained 9 (nine) bacterial isolates which are distinguished based on incubation time and morphological characters.
