Abstract

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

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

ABSTRACT The aims of this study are to determine the condition of the coral reefs including percentage live coral cover, the diversity index, the uniformity index, and the dominance index of  lifeform coral at waters of Tidung Island Kepulauan Seribu Jakarta. This research has been conducting from 2018 May 7th - 17th at the waters of Tidung Island.The research station was divided into 3 stations based on environmental characteristics with 2 different depths ; 3 and 7 meters. The research station is a coral conservation area, snorkeling area, and natural area. Data of coral reef was obtained by using the Line Intercept Transect (LIT) method. The results showed that the conditions of coral reefs at stations 1 and 2 respectively in the bad category with the percentage of cover area are 3.52% and 10.84%. Whereas at station 3 the condition of coral reefs is in the medium category with the percentage of cover area is 30.01%. The low percentage of coral cover is caused by rising sea water temperatures, port activities and human activities. Water quality such as temperature, salinity, pH, current velocity and brightness at the study site is quite good for coral recovery and growth. Keyword : LIT, Coral Recovery, Diversity, Uniformity, and Dominance Index

Abstract

 ABSTRACT Zooxanthella which acts as endosymbionts in corals requires optimal light for photosynthesis. This research was conducted in February 2019 which took place in the waters of the Kasiak Island of West Sumatra. Samples were analyzed at the Laboratory of Marine Biology, Faculty of Fisheries and Marine, University of Riau. This study aims to determine the abundance of zooxanthella and the effect of differences in light intensity on the abundance of zooxanthella on Acropora sp.. So the information is obtained about the optimal light intensity on the abundance of zooxanthella. Based on the results of observation, the abundance of zooxanthella in Acropora sp coral decreased with decreasing light intensity, so it can be seen that there was an effect of the difference in light intensity on the abundance of zooxanthella on Acropora sp. The abundance of zooxanthella in control (light intensity 60-93 μE/m2s) is 8.282.997 cells/cm2, in treatment 1 (light intensity 58 μE/m2s) amounting to 3.460.841 cells/cm2, in treatment 2 (light intensity 26 μE/m2s) of 2.113.296 cells/cm2, and in treatment 3 (light intensity 0 μE/m2s) of 588.065 cells/cm2. It was also found that the description of Acropora sp. Coral transplant business will be more optimally performed on the light intensity of 60-93 μE/m2s. Keywords:Zooxanthella, Acropora sp, Light Intencity

Abstract

Penelitian bertujuan untuk menganalisis tingkat perkembangan  wilayah untuk pembangunan pertanian berbasis komoditas unggulan di kabupaten kutai kartanegara. Penelitian menggunakan metode analisis skalogram,  analisis sentralitas, dan analisis komoditas unggulan dan andalan, dengan dukungan data sekunder dan data primer dari berbagai sumber. Sesuai hasil analisis disimpulkan; a) Pembangunan pertanian berbasis wilayah dibangun melalui tiga zona yaitu zona hulu berpusat di Kecamatan Kota Bangun, zona tengah berpusat di Kecamatan Tenggarong, dan zona pantai berpusat di Kecamatan Muara Jawa; dan b) Pembangunan pertanian dilaksanakan dalam 3 tahap, yaitu tahap pertumbuhan (tahap 1), tahap pengembangan (tahap 2), dan tahap pemantapan (tahap 3). Tahap 1 adalah penguatan on-farm didukung pengembangan industri hulu. Tahap 2 dan 3 fokus pada pengembangan industri hilir (off-farm) dan perluasan investasi pembangunan industri penunjang didukung oleh kegiatan on-farm; c) Komoditas unggulan di Kabupaten Kutai Kartanegara antara lain : padi sawah, jagung dan singkong (tanaman pangan); kelapa sawit dan karet (tanaman perkebunan); sapi potong, kambing, ayam kampung, ayam pedaging dan ayam petelur (peternakan); dan perikanan laut, tambak, dan keramba (perikanan); dan d) Pembangunan pertanian berbasis wilayah akan mendukung pembangunan berkelanjutan di Kabupaten Kutai Kartanegara yaitu meningkatkan kelestarian lingkungan melalui konservasi tanah, air dan tanaman.
