Abstract

                                                 AbstrakShoreline changes isprocesses of accretion and abration, triggered due to natural and human activities factors in coastal areas.This research wasconductedat April 2018 in the coastal district of West Rangsang District of Meranti Islands.This research was aimed to determinewide and rate of shoreline changeby using satellite landsat imageat 2002 until 2018 with DSAS 4.3 (Digital Shoreline Analysis System). The research used surveymethod  and determination of sampling location by purposive sampling. Measurement of physical parameters is done in situ. The analysis of shoreline changes using 4 Landsat images (2002, 2007, 2015 and 2018) at DSAS approachs with the NSM (Net Shoreline Movement) for distance change and EPR (End Point Rate)for the rate of change. Shoreline changes in West Rangsang district are influenced by strong wave of Malacca Strait, during the last 16 years there has been accretion in seigomeng, melai, part of bantar andanak setatah village, with the highest average accretion rate of 8.88 m / year, mean distance change 138.1 m and the area of change 108 Hecktar and abrasion in the village of Permai, part of Bantar village and children setatah with average highest abrasion rate 4,93 m / year with mean distance change 76,6 m and area 1101 Hecktar. The wave energy is 2.94 until 4.9 Nm / m2 and the current velocity is 0.40 until 0.50 m/s with the flat beach tipe.Keyword: Shoreline Changes, Rangsang Barat, Accretion, Abration, Landsat image, DSAS

Abstract

 ABSTRACT This research aim to determine the effect of feeding time on the growth performance and survival  rate of red tilapia (Oreochromis niloticus) by using Recirculation System. This research was conducted on March-May 2018 at Technical Service Unit (UPT) of Bengkalis, Province Riau. This research was using experimental method by completely random design (RAL) one factor with three replications. The treatments were: 1. Feeding twice a day, 2. feeding three times a day, 3. Feeding four times a day and 4. Feeding five times a day. The feed given is pellet PF-800 with the amount of 4% of fish a day weights everyday. The results showed that a different feeding times influenced the growth performance and survival rate of red tilapia using recirculation system. In addition, it  also  affected  the  absolute  weight  growth,  absolute  length  growth,  feed efficiency and feed conversion ratio. The best feeding time was three times daily because it showed significantly different results compared to feeding times twice, four times, and five times a day. So that while being applied in terms of economy, feeding three times a day was the most efficient by giving the absolute weight growth was 13,23 g, specific growth rate was 2,86% survival rate was 86,67% feed efficiency was 184,80 %  and feed conversion ratio was 0,53%. Keywords: recirculation system, red tilapia, feeding time food

Abstract

ABSTRACT            Red snakehead (Channa micropeltes) fish is one of freshwater fish species that inhabit the Lubuk Siam Lake. Information on the type of red snakehead fish food, however, is limited. A research aims to understand the stomach content of red snakehead fish has been conducted in January to March 2018. The fish was sampled three times, once/month. There were 54 fishes captured. Stomach contents were analyzed using in a gravimetric method and data obtained were used for calculating the Preponderance Index (PI). Results shown that the food of red snakehead fish consists of fish, crustaceans and plant material. The main food of red snakehead fish is fish (PI 95%), complementary food is shrimp (PI 4%) and plant as additional food (PI 1%). Based on the data obtained, red snakehead fish can be categorized as pure carnivore.Keywords: Carnivore, Preponderance Index, Gravimetric, Oxbow Lake

Abstract

AbstractMystus nemurus C.V is one of freshwater fish that inhabit the Banjiran swamps. To understand the type of food consumed by M. nemurus, a study has been conducted on February - March 2018. There were 100 fishes captured, that was consisted of 71 fishes with filled stomach and 29 fishes with empty stomach. Stomach content of the fish was analyzed as a basis to calculate the Preponderance Index (PI). Results shown that the main food of M. nemurus was fish (38%), the complementary food was unidentified debris (31%), and additional food was plant (24%), insects (4%), crustacean (1%), and domestic waste (2%). Keywords: Catfish, fish food, Index of Preponderance, Flooded Area

Abstract

ABSTRACT                The aims of study was to analyze the relationship of planktonic diatoms  abundance with the concentration of nitrate, phosphate and silicate from the Teluk Buoof waters. Placement of sampling location using purposive sampling that was by dividing the research location into four station with 3 point of sampling at each station in Teluk Buo waters which serve as research location. Field sampling was conducted in March 2018 and the observation and identification of planktonic diatoms were conducted in Marine Biology Laboratory of the Fisheries and Marine Faculty of Riau University. The results showed that nitrate concentration in Teluk Buo waters ranged from 0.0125 - 0.0333 mg/l, phosphate concentration ranged from 0.0413 - 0.0841 mg/l,and  silicate concentrations ranged from 0.0228 - 0.0354 mg/l. Nine species of plantonic diatoms were finded in Teluk Buo of waterswasBiddulphia sp, Isthimisp, Coscinodiscus sp, Flagilaria sp, Nitzschia sp, Navicula sp, Aulacoseira sp, Bacillaria sp, dan Cymbella sp. The average abundance of diatoms in these waters 181-250 ind/l. Regression test results, nitrate correlation value with diatomic abundance shows a relationshipwas positive, while the value of phosphate and silicate correlation with diatomic abundance shows a relationshipwas negative.           Key word : Planktonic Diatoms, Nitrate, Phosphate and Silicate, Teluk Buo Waters

Abstract

ABSTRACT The aim of this research is to know the condition of coral reefs including the live coral cover of the waters of Cempedak Island Bintan.This research had been conducted in the waters around Cempedak Island Bintan in May 2018.The research station is divided into 3 stations based on environmental characteristics with a depth of 5 meters.Research stations include Eagle Rock, near Jetty and Deadmans Beach. The data of coral reefs were collected by using Underwater Photograph Transect (UPT) method. Data were analyzed using Coral Point Count with Excel extension (CPCe) application.The results showed that coral cover on the study sites ranged around 23.87% to 47.87% which can be classified as poor  to moderate category sequentialy.At each station can be seen a high percentage is in station III with value 47.87%, whereas at station II coral percentage is low or bad with value 23.87%.The low coral cover is caused by the strong ocean currents causing sediment staggeration so that the sediment covers the coral surface and because of the current, the number of races and dead corals found with algae to cause the coral is damaged as in station II. The quality of water such as temperature, salinity, pH and visibility of the research location was good for coral reefs recovery and growth. Keyword: Coral reef, Cempedak Island, Underwater photograph Transect (UPT),  Current Speed

The activity carried out by fishermen to meet the needs of everyday family despite changing weather conditions at the time of the turn of the seasons and the seasons causing certain conditions area of the catchment is not very good even harm­ful. Load a dependent family and caused most of the fishermen have to keep doing activities on the ocean even though the weather was not good or looking for another job if it couldn't sail or conduct arrest this research also shows that the behavior the adaptation was done by the fisherman Village Posek by changing the capture tool, change the area of arrest and at the moment weather conditions cause they can't conduct arrests. The activity at the time of arrest is not doing that is looking for another job like being a construction worker, managing the estate, repairing the ship, captured near the beach and looking for work in other areas but some are just waiting for the. Keywords: Adaptation, Change of Season, Fisherman
