Abstract

ABSTRACT Koto Panjang Reservoir has been contaminated by lead (Pb) and accumulated in fish. The reservoir inundation flow ends at the reservoir outlet inhabited by tilapia (Oreochromis niloticus) which can accumulate high amounts of Pb. This study aims to determine the content of Pb in the gills and muscles of tilapia. The fishing survey was conducted in August - September 2021. Samples of gills and muscles of tilapia (O. niloticus) is taken from the catches of local fishermen. Pb content analyzed after acid extraction. The results showed that the lead (Pb) content in the gills was 0.0567 mg/kg higher than in the muscles (0.0049 mg/kg) and the content was still below the threshold so it was suitable for consumption.Keywords: Lead gill,muscles reservoir tilapia

Abstract

AbstractUsed plastic bottles can be used for biofilter media as microorganisme may attach in the bottle surface. To understand the effectiveness of the number of plastic bottles in the anaerob tank in reducing MBAS and phosphate in laundry waste, a research has been done in October-December 2019. This research uses used plasctic bottles with 11 cm height and 6 cm diameter. There were 3 treatments applied, namely P1 (25 bottles) with surface area 11.540 cm2,  P2 (50 bottles) with surface area 23.080 cm2 and  P3 (75 bottles) with surface area 34.619 cm2, 3 replications in each treatments. The seeding time of the biofilm was 25 days. The effectiveness of MBAS decrement was 56.3%, 73.7% dan 80.9% in P1, P2, and P3respectively. While the effectiveness of phospate decrement was 54.9%, 73.3% and 85.0%. in P1, P2, and P3 respectively. Based on data obtained, it can be concluded that the biofilter that was completed with plastic bottleswas able to reduce the MBAS dan phosphate in the laundry liquid waste and P3 provided the best result.Keywords: anaerob, bacteri, waste management, plastic bottle re-use
