Abstract

AbstractThis study discusses the content of heavy metals Fe suspended loads on the Sail River, Pekanbaru City. The study aimed to determine the content of heavy metals Fe and suspended solids in the waters of the Sail River. This research was conducted in February - March 2019. Suspended solid samples were taken from 3 stationsof the Sail River. Samples were taken at each station according to the depth, namely the sampling point on the surface of the water, the sampling point in the middle of the water, and the sampling point at the bottom of the water. Sampling time is done every 3 times in 1 month. The results were obtained, the average suspended solids at Station Iwere 149 mg/l, Station IIwas 237 mg/l, and the sampling point was 114 mg/l. The average content of heavy metals Fe in suspended solids at station Iwaters are Fe 2.95 mg/l and 0.152 mg/l, station II namely Fe 2.786 mg/l and 0.125 mg/l, and station IIInamely Fe, which is 2.86 mg/l and 0.147 mg/l. The higher of Supended Solid in water the higher of heavy metal. Keywords: station of the river, depth of the river

Abstract

AbstractBathymetry is a measure of high and low seabed where bathymetry maps provide information about the seabed.This research was conducted in November 2018 - January 2019,in the waters of the Sasak coast of West Pasaman district. This study aims to determine the depth and shape of the seabed morphology as well as the type of sediment,The research method used is a survey method, then the sampling point is determined by purposive sampling,the fixing fixation point consists of 100 points and 9 sediment sampling points.Then sediment analysis and bathymetry data processing are performed. The results showed the depth of water in the study area between 4 to 14.5 meters and has a type of seabed morphology that is classified as gentle.The distribution of basic sediments in the study area consists of three (3) types of sediment fractions, namely gravel, sand and mud,The type of sediment at each sampling point is based on the proportion of gravel particle content,sand and mud are classified according to Shepard's triangle, weight percentage fraction and sediment type at each station point.Keywords :Bathymetry, Sediment.

Abstract

Abstract The laundry waste is rich in MBAS and phosphate and its need to be processed before being flown to environment. This study aimsto determine the ability of  abatchbiofilter system in reducingthe phosphate and MBAS content. This study has been conducted in January-March 2018.The laundry liquid waste (175 liters) was kept in 2 anaerobik tanks that was completed with gravel, sand and palm fibers media for ten days.Then the waste was flown to aerobik tanks (coconut shellcharcoal media) for seven days. Finallythe wastewas treated in a phytoremediation pondthat was completed withSalvinia molestafor fifteen days. By the end of the experiment, the phosphate reduced from 11.6-0.8 mg/L (the effectiveness was 92.67%)and the MBAS reduced from 10.5-1.3 mg/L (the effectiveness was 87.16%). Other water quality parameters such as pH was normal and temperature and DO were improved. The treated waste was then used for rearing Cyprinus carpio (5-7 cm TL) for 10 days. The survival rate of the fish was 89%. Based on data obtained, it can be concluded that the combination of biofiters and phytoremediation system using Salvinia molesta is effective to reduce the phosphate and MBAS content in the laundry liquid waste. Keyword:waste water, detergent contaminated waste, bacth system, surfactant

Abstract

Abstract Thynnichthys thynnoidesis one of freshwater fishes that inhabit the Teluk Petai lake.A research aim to understand the information on stomach content and it’s relationship with size, sex and environmental condition.This research has been done on March to April 2019. Fish samples were captured using sempirai and nets. Sampling was conducted 4 times in two months. Type of food present in the stomach content of fish was analyzed using a volumetric method and the IP (Index of Preponderance) was calculated. There were 95 fish captured. Result shown the feed of T. thynnoidesphytoplankton (Bacillariophyceae, Chlorophyceae, Cyanophyceae) and Zooplankton (Rotifera). The main food of T. thynnoideswasBacillariophyceae(57.62%). There was no differences in the main food of males and female fishes. The water quality parameter were as follows: temperature 30.5 0C, brightness 76.25 cm, pH 6, DO 6.44 mg/L, CO2 9.75 mg/L. Based on data obtained, it can be concluded that theT. thynnoides is an plankton feeder.Keywords:Thynnichthys thynnoides, StomachContentAnalysis, Index of Preponderance, TelukPetaiLake

Abstract

ABSTRACTThis study aims to determine the best types of natural food for growth performance, survival rate and color brightness of neon tetra fish (Paracheirodon innesi). The method of this research was using the experimental method with Completely Randomized Design (RAL) by using one factor of 4 treatment levels and 4 replications. The tratments were using pellet (control), Tubifex sp, Moina sp and Bloodwarm. The fry size was around 1.2-1.5 cm and weight was 0.065 gthen reared in the aquarium by 15 L of water and 15 fishes of stocking density each aquarium. The fish were reared for 40 days and feed is given as much as 10% of biomass weight, e times a day of feeding frequency. The results showed that the best treatment was Tubifex sp by giving absolute weight growth for 0.14 g, absolute longevity for 0.58 cm, specific growth rate for 2.99% and fish survival for 98%, while the best color brightness by giving a Bloodwarm. The conclusion is different types of natural diets significantly affect the growth performance, survival rate and color brightness of neon tetra fish (Paracheirodon innesi).Keywords: Natural food; Growth; Survival rate; Color brightness; Neon tetra; Paracheirodon innesi.

Abstract

ABSTRACT             This research was conducted in March to April 2019. The purpose of this research was to find out value of total suspended solid (TSS) content,value of phytoplankton abundance, and the relationship between the total suspended solid (TSS) and the abundance of phytoplankton. This research used survey method, there is arefour sampling stations with three replications in each station. The results showed, that the highest average of TSS contentin Padang Strait waters was found in Station 3 (241,33 mg/l) and the lowest in Station 4 (193,33 mg/l). The types of phytoplankton was found in Padang Strait waters was 14 types, they areBacillaria sp, Closterium sp, Coscinodiscus sp, Isthmia sp, Rhizosolenia sp, Synedra sp, Navicula sp, Skeletonema sp, Thalassionema sp, Oscillatoria sp, Nitzschia sp, Hantzschia sp, Amphora sp, and Pleurosigma sp with the most dominant types are Isthmia sp and Rhizosolenia sp. The highest abundance was found in aroundMangrove Area of Pangkalan Jambi Village (3247,59 ind/l) and the lowest was found inSungai Selari Port (1538,18 ind/l).Based on simple linear regression, the relationship ofTSS content with phytoplankton abundance showed a intense negative relationship, it means that the increasing of TSS content will decreasing abundance of phytoplankton in Padang Strait waters. Keywords:Padang Strait, TSS, Abundance of Phytoplankton
