Abstract

ABSTRACT This research was conducted in April-May 2019 in the waters of Poncan Island, North Sumatra Province, which aims to determine the large nutrient content of substrate (nitrate and phosphate), the level of seagrass density Enhalus acoroides, and to determine the effect of nutrient content of the substrate on the density of seagrass Enhalus acoroides. Determination of the research station by purposive sampling and research sampling using the transect line method. The results showed that the highest nutrient content of substrate (nitrate and phosphate) was found at Station II which has a type of muddy sand substrate and the area is influenced by tourist activity.Nitrate concentration values were 0,074 mg / l and 0,122 mg / l for phosphate concentration values.The highest seagrass density was in Station II with a value of 74,22 stands / m2which had the highest nitrate and phosphate content, and the lowest seagrass density was in Station III which had the lowest nitrate and phosphate concentrations.Simple linear regression test results of the influence of nutrient substrate on the density of seagrass with a value of R2(coefficient of determination) = 0,27 (nitrate), 0,40 (phosphate) indicates there was effect of nitrate and phosphate on the density of seagrass Enhalus acoroides. Keyword: Nutrient Substrate, Nitrate and Phosphate, Seagrass Density

Abstract

The pusposes of research to find out learning result using cooperative learning model of type Numbered Heads Together (NHT) with scientific approach learning model of type Problem Based Learning (PBL), specially on Basic electricity and electronics Subjects at SMK Negeri 1 Sumbar. This is probably because in the learning process students are less active and less participate in teaching. This research is a quasi experimental study with pretest-posttest control group design. Experimental I class used cooperative learning model of Numbered Heads Together (NHT) and Experimental II class used scientific approach learning model of Problem Based Learning (PBL). The results of study have shown that average of the experimental I class test result is 83,13 while the Experimental II class has provided the average outcome of  78,29. However, this learning shows that there is a significant effect of student’s learning outcome between the usage of cooperative learning model of typeNumbered Heads Together (NHT)rather than scientific approach learning model of type Problem Based Learning (PBL)on Basic electricity and electronics subject. The hypothesis test(t-test) shows that tc> tt( 2.12 > 2.05). Therefore,applying cooperative learning model of type Numbered Heads Together (NHT) is more effective than scientific approach learning model of type Problem Based Learning (PBL) .Keywords: Numbered Heads Together, Problem Based Learning, Learning Outcomes

Abstract

The problem in this study is the low average learning outcomes of students on subjects Applying Digital Engineering Basics is under the Minimum Criterion of completeness which has been established SMKN 1 Batipuh is 75. This study aims to determine the effect of application of Team Assisted Individualization model to learning outcomes on subjects Applying Digital Engineering Basics in Audio Video Techniques department at SMKN 1 Batipuh. The type of this research is experimental research with pre experimental design with intact group comparison design. The sample of research is class X TAV 2A as experiment class using Team Assisted Individualization model and class X TAV 2B as control class using direct learning model. Data is collected  from post-test in the experimental class and control class, then analyzed for homogeneity, normality and hypothesis test. From the experimental class results obtained an average value of 80.71, while the control class gets an average value of 75.79. The result of hypothesis calculation at significant level α = 0,05 got tcount> ttable that is 2,442 > 2,056, because big tcount of ttable, null hypothesis (H0) rejected and alternative hypothesis (Ha) accepted.itCan be concluded mean at the real level, this research shows that, there is work on of student learning result which signifikan between usage of Team Assisted Individualization type with direct learning model on subjects Applying Digital Engineering Basics of student of Audio Video Technique at SMKN 1 Batipuh. So the Team Assisted Individualization learning model is better than the direct learning model. Keywords: Applying Digital Engineering Basics, Team Assisted Individualization model, direct learning model, pre experimental design, learning outcomes.

Abstract

Penelitian ini dilakukan pada Bulan April 2019 dengan tujuan untuk menganalisis kondisi kesehatan terumbu karang dan kondisi kesehatan ekosistem terumbu karang di Perairan Kawasan Mandeh. Penelitian ini dilakukan dengan menggunakan metode survey dimana setiap pulau terdiri atas 3 stasiun dengan tiap stasiun terdiri atas 2 kedalaman yaitu 4 meter dan 9 meter. Pengambilan data persentase tutupan karang dan tingkat resiliensi karang yang dinilai berdasarkan persentase patahan karang dilakukan dengan metode Underwater Photo Transek (UPT), Sedangkan pengambilan data ikan dilakukan dengan metode Underwater Visual Census (UVC). Berdasarkan hasil penelitian yang dilakukan diketahui bahwa kondisi kesehatan terumbu karang yang paling baik disekitarnya adalah Pulau Marak.  Sedangkan kondisi kesehatan terumbu karang yang terburuk adalah Pulau Pagang. Ukuran dalam menentukan kondisi kesehatan terumbu karang karang didasari oleh sehatnya terumbu karang itu sendiri dan ekosistemnya. Terumbu karang yang sehat memiliki persentase tutupan karang batu hidup yang tinggi dan disertai oleh tingginya tingkat resiliensi atau pemulihan yang dimiliki hewan karang saat mendapat gangguan. Sedangkan ekosistem terumbu karang yang sehat adalah terumbu karang yang mampu memproduksi sumberdaya ikan sebanyak-banyaknya.

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

ABSTRACT This research was conducted in July 2018 with the aim to determine the metal content of Zn, Cr and Cu in brown Algae (Sargassum sp.) From Bungus Waters of West Sumatra Province and to determine the value of Metal pollution index (MPI) in Bungus Waters of West Sumatra Province.Determination of sampling location using purposive sampling, namely by considering the state of the research area. Sampling was carried out in areas with relatively different anthropogenic activities and analysis of heavy metal content was carried out at the Marine Chemistry Laboratory, Faculty of Fisheries and Marine, University of Riau. The results showed that the Zn metal content in brown algae ranged from 55,033 - 70,250 µg / g, where the highest concentrations were at Station 3 and the lowest at Station 1. The concentration of Cr metal in brown algae ranged from 18,500 - 32,833 µg / g, where the highest concentration was found in Station 3 and the lowest at Station 1. The concentration of Cu in brown algae ranges from 2,833 - 7,500 µg / g, where the highest concentration is at Station 3 and the lowest at Station 1. The MPI value of Bungus Waters of West Sumatra Province is 19.44, the value is still normal when compared with research conducted in other regions using Algae samples.Keywords: Zn, Cr and Cu metals, Brown Algae (Sargassum sp.), Bungus waters
