Abstract

Horseshoe crab, Carcinoscorpius rotundicauda is frequently found in the coastal zone of Bintan Bay of Riau Islands Province. The study was conducted from August to September 2016 in coastal area of Kampung Gisi, Bintan bay. The aims of the study were to analyse the population structure and morphometric characters of horseshoe crab and its relation to the coastal environmental characteristics. Sampling of horseshoe crab was taken using belt transect method, and coastal environmental parameters were measured in-situ. The results show that b values of length-weight relationship were found to be 3.3 (male) and 2.6 (female) respectively. Furthermore, the growth pattern of males were positive allometric, and females were negative allometric. Horseshoe crab are closely related to sandy mudflats sediment, brackish water salinity and mangrove habitat distribution.  Keywords: horseshoe crab, population structure, morphometry, environmental characteristics, Bintan Bay

Penelitian tentang validasi metode penentuan merkuri pada sampel waste water treatment plant (WWTP) dari PT. LNG Badak Bontang, Kalimantan Timur dengan menggunakan teknik bejana uap dingin spektrofotometer serapan atom (CV-AAS) telah dilakukan. Untuk memperoleh hasil pengukuran yang valid, telah dilakukan pengukuran beberapa parameter yang berpengaruh dalam validasi metode. Hasil penelitian menunjukkan larutan SnCl2 20% dapat digunakan sebagai reduktor. Kinerja analitik pengukuran yang diperoleh sangat baik, ditunjukkan dengan nilai linearitas (r) ≥ 0,995; LOD sebesar 0,2530 ppb, LOQ sebesar 0,8432 ppb, MDL sebesar 0,6427 ppb, pengulangan dan kebolehulangan dinyatakan&nbsp; sebagai %RSD &lt; 2/3 nilai KV Horwitz. Keakuratan metode ini sangat baik dengan nilai presentase perolehan kembali sebesar 114,88%. Berdasarkan hasil penelitian ini, metode CV-AAS dapat digunakan dalam penentuan Hg pada sampel WWTP dengan hasil yang valid.
