Abstract

Rain-fed swamp is a type of freshwater swamp found in Pampangan Sub district of Ogan Komering Ilir Regency,South Sumatra, characterize by fluctuation of water level related to variation of rain precipitation. This research was carried out in Pampangan swamp by collected phytoplankton samples in 5 different month i.e. May, July, October and December 2011 and February 2012 in order to find out the diversity of phytoplankton in rain-fed swamp. Phytoplankton samples were collected by filtering 100 L swamp water through plankton net and 50 ml of filtrate were used for identification. Water quality parameters such as ph, alkalinity, hardness, conductivity, total-P, total-N, and Chlorophyll-a content also observed. The result showed that phytoplankton community in rain-fed swamp composed of 40 species member of 3 class; Bacillariophyceae (22 species), Chlorophyceae (14 species), and Cyanophyceae (4 species). Key words: Phytoplankton, rain-fed swamp, Pampangan

Abstract

Study bacterial content of the Musi river water at high tide and low tide in the city of Palembang was implemented in January through April 2014. Objective research to determine the water quality of the river Musi at high tide and low tide is based on the total number of bacteria and bacterial coliformnya. This study used a different test (T-test) consisting of 2 factors and 5 replications. Observation parameters consist of: the total number of bacterial colonies growing on media NA, and the number coliform test results obtained from the estimation and confirmation tests. The data obtained by different test T-test. The results of the calculation and analysis of the differences found in total bacterial counts at high tide and low tide, it appears that events tidal effect on the bacterial content in the water of the river Musi. Total content of more bacteria at low tide than at high tide. Key words: water river Musi, the total number of bacteria, and coliform bacteria

Abstract

Kluwek (Pangium edule Reinw.) has many advantages, one of the advantages is as the material of insecticide by using cyanide acid that was toxic in seed. It needed the evidence to prove the advantages is as the material of insecticide of kluwek seed toward organism which was sensitive with cyanide acid material. The organism which was used: roach (Blatella germanica L.). The problems of this study were did the use of the extract kluwek seed (Pangium edule Reinw.) as the plants insecticide toward mortality of the roach (Blatella germanica L.). The method of this study has experimental method with Completely Randomized Design (CRD) at the six treatments and four replications, Duncan Multiple Range Test (DMRT) with SPSS version 16.0 programs. The result of this study were kluwek seed had significance effect toward mortality of roach (Blatella germanica L.) in the treatment (P5) with concentrate (125%). The roach was dead in twelve hour average. It means that (1) Use of the extract of kluwek seed as the plants insecticide with concentrate among 25%, 50%, 75%, 100% and 125% had significance effect toward mortality of the roach (Blatella germanica L.). Key words: mortality, kluwek seed, and roach

Abstract

This study aims to determine the metal content of cadmium (Cd) in mussel (Corbicula sp.) in Palembang Musi River. The sampling method was purposive sampling method. Based on the source of metal contamination of cadmium (Cd) in the Musi River in Palembang administrative region, the location of the study were divided into eight stations. The results showed the average metal concentrations of cadmium (Cd) in mussel tissue (Corbicula sp.) of 0.6801 mg / kg with a range of concentrations between 0.4320 mg / kg - 0.9470 mg / kg with the highest concentration in the area Pulokerto and lowest in the shipyard area of PT. Mariana Bahagia. Cadmium metal concentrations in mussel tissue (Corbicula sp.) is still under No. SNI. 7387 the year 2009 is equal to 1.0 mg / kg. Key words: cadmium, mussels, Musi River
