Abstract

AbstractPangasius polyuranodon is one of freshwater fishes that inhabit in the Kampar Kiri (Mentulik) and Kampar Kanan (Teratak Buluh) River in Riau. Pangasius polyuranodon known as opportunist fish, but information on its stomach content is limited. A research has been conducted at October to November 2017 to understand the stomach content of this fish. Sampling  was conducted once/week for a month period. There were 88 fishes captured, but 15 of them had empty stomach and its cannot be used for stomach content analysis. The analysis was conducted using the gravimetric method. Stomach content was analyzed as a basis to calculate the Preponderance Index (PI). Result shown that the main food of the fish from the Kampar Kiri River was insect (PI 95%), the complementary food was plant (PI 4%), and the additional food was debris (PI 1%). The main food of the Kampar Kanan River was bivalve (PI 76%), the complementary food was human waste (PI 16%), and the additional food was insect (PI 3%), domestic waste (PI 3%), plant (PI 1,8%) and debris (PI 0,1%). Based on data obtained, this fish can be categorized as omnivore.Keywords: Pangasius polyuranodon, Stomach Content Analysis, Gravimetric, Mentulik and Teratak Buluh River.

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

                                               AbstrakThis study was aimed to find out how the perception of parents whose children dropout in junior high school. In addition, this study also focuses on determining the relationship between parents' opinions about school dropout and the characteristics of respondents in the Perlis village Pangkalan Berandan subdistrict Langkat district North Sumatra province. With the respondents no less than 32 people are parents whose children drop out.The results of this study indicate that the perception of the parents were whole parents who did not go to school to experience that good education for children. Education is important for the future of the child. Children's behavior can also be influenced by education. Children who stop schooling at an equivalent lower level usually do not think of education because they are busy to earn an income. The research results showed that the parent-perception relationship with the fishermen's character had a significant relationship with income, the number of dependent and fishery education levels. It seems that the income, the number of dependents and the level of education have a relationship with the perceptions of parents. Keywords: Education, Perception, Fishermen

Abstract

AbstractMacrozoobenthos is a living organism that is relatively sedentary (sessile) and has varying adaptability to environmental conditions. In addition, macrozobenthos is also widely used as an indicator of pollution. This research was conducted in the waters of Pasumpahan Island, Bungus Subdistrict, Padang City, West Sumatera Province in April 2018, aiming to know macrozoobenthos community structure which includes: type, abundance, index of species diversity, uniformity index, dominance index and distribution pattern. Sampling using line transect method is done on 3 stations. The results of the study found 4 classes of macrozoobenthos with 9 species, where the value of macrozoobenthos abundance obtained ranged from 3.22 to 3.78 ind/m2. The index value of diversity of species ranged from 0.40 to 0.57 is relatively low, while the value of uniformity index ranged from 0.12 to 0.19 is not balanced, the value of the dominance index ranged from 0.12 to 0.18 ie no species which dominates and the value of the distribution pattern ranges from 3.21 to 5.09 with the pattern of distribution in groups.Keywords: Makrozoobenthos, Intertidal Zone, Pasumpahan Island, Community Structure

Abstract

 ABSTRACTThis research was conducted in January 2018 in the fishing gear laboratory, Utilization of Fishery Resources Department, Faculty of Fisheries and Marine, University of Riau. The purpose of this research is to know the effect of the current on the appearance of jermal fishing gear and the ideal current velocity for jermal fishing gear. Measurement of the current velocity in the flume tank at the start of the 5-50 Hz frequency measured using a current meter device, obtained the lowest speed of 2.7cm / sec and the highest 47.2 cm / sec indicates a positive correlation, the higher the frequency used, the more high current velocity generated. The result of this research is the higher the current velocity, the higher the position of the capture device from the bottom of the water, the left and right shift position, the period of up and down movement and the period of left-right movement of the jermal fishing gear and the ideal current velocity for the jermal fishing gear that obtained in this study is 11.1 cm/sec, because at this speed all the capture part is open, and also the value of the movement and the resulting period is small.Keyword: current velocity, jermal fishing gear, flume tank

Abstract

 ABSTRACT                Microalgae are very potential to be developed as biofuel feedstocks when compared to food crops because they have several advantages such as rapid growth, high productivity, enabling the use of freshwater and seawater, and production costs are not too high. Spirulinaplatensis has a high nutrient content so it is used as a health food ingredient. Once the importance of the role of nutritional value of S. platensis for humans and some marine organisms, then the right culture medium to get the maximum nutritional content needs to be studied more deeply. This study aims to determine the effect of different doses of nutrition on the density of biomass cultivation of S. platensis microalgae with indoor and semi outdoor system. This research has been conducted from April to May 2018. The method by used the experimental method. The data obtained were analyzed statistically using simple linear regression equation. The results showed that the influence in the dose of nutris media guillard, S.platensis increased with the dose of nutrients as much as 0.60 ml either indoor or semi outdoor system. The relationship experienced between biomass with different doses of nutrients is a positive medium with both indoor and semi-outdoor systems, this can be seen from the results of simple linear regression test, namely r = 0.3443 for indoor system and r = 0.4492 for semi-outdoor system. As for the amount of biomass density S. platensis in the semi-outdoor system the amount of biomass density is higher than the indoor system.Key words: Microalga, Spirulina platensis, Sediment, Media Guillard
