Abstract

Abstract The rapid growth of industrial sectors in various countries leads to an increase in greenhouse gas emissions such as carbon dioxide (CO2) in the atmosphere. One important aspect of reducing carbon gas is the maintenance of forests and oceans to store carbon. One of the potential marine resources for storing CO2 is the seagrass. Waters of the North Sea Penyengat Island has a community of seagrasses composed by various types, one of which is Enhalus acoroides which has an important role as carbon store. This research was conducted in October-November 2017 in the waters of East Sea of Penyengat Island which aims to find out the condition of density and biomass on sea grass in Above ground and Below ground (rhizoma and root) density to seagrass biomass on seagrass. Data were obtained by using the quadratic transect method performed on 4 stations. The results showed that the density of seagrass in the study location was moderate, where the density of seagrass Station III was higher than other stations. The greatest biomass value is found in the rhizomes and roots of seagrasses in all four stations. Less seagrass areas are anthropogenic, ie station III which has a greater biomass potential than the seagrass area with the opposite condition. Keywords: Global warming, Biomass, Seagrass, Penyengat island.

Abstract

This research was conducted in April 2016 at the Strait of Bengkalis, Riau Province. The aim of research is to determine the pattern salinity and temperature distribution at ebb tide and flood tide. Research used survey method. Tide data obtained were presented in the form of chat the map and discussed descriptively. Based on the research it showed that average salinity at flood tide 23.56‰ and ebb tide 22.90 ‰. The average of salinity at ebb tide was lower than flood tide. In contrast to the temperature, the temperature measurement at flood tide lower than ebb tide and the average value at flood tide 31,18ºC and ebb tide was 31,53ºC. The results showed that distribution of salinity and temperature during flood tide and ebb tide is fluctuated. The pattern of distribution of salinity, temperature and other environmental parameters (pH, transparency, current velocity and depth) were different betwen the flood tide and ebb tide.Keywords: Salinity, Temperature, Distribution Pattern, Bengkalis Strait

Abstract

Mangrove is a tree that normally grows in the intertidal zone of marine coastal environments. This study aims to estimate the carbon content of mangrove forest ecosystems within a certain area, to analyze biomass differences, carbon stocks and CO2 uptake and to analyze the effect of mangrove density on biomass, carbon stock and CO2 uptake. This research held on February 2017 by survey method and used the data of mangrove species, it’s number and diameter of breast height (DBH) on each sub plot. Measurement of mangrove biomass was done allometric equation method. The result of carbon stock and CO2 uptake in mangrove indecates that Station III was higher than Station I and II. The average yield of mangrove carbon stock and CO2 uptake is 1333,99 ton / ha and 4891.30 ton / ha. For the highest soil organic carbon is found in Station 1 with an average soil organic carbon of 1446.75 tons / ha. The density of mangrove biomass, carbon content and CO2 uptake which has a strong relationship. The content of biomass, mangrove carbon and CO2 uptake were significantly different (p <0.05) between stations. Keywords: Mangrove, Carbon, Jorong Ujuang Labuang

Penelitian ini dilaksanakan pada bulan Februari 2017 bertempat di Muara Sungai Rokan,Kabupaten Rokan Hilir. Penelitian bertujuan untuk mengetahui tingkat kesuburanperairan dan tingkat kekeruhan muara Sungai Rokan serta mengetahui hubungannya.Metode yang digunakan selama penelitian adalah metode survei dan penentuan titikstasiun dengan cara purposive sampling. Pengambilan sampel parameter Fisika danKimia secara in situ seperti kekeruhan, kedalaman, kecerahan, kecepatan arus, suhu,salinitas, oksigen terlarut (DO), derajat keasaman (pH). Hasil analisis kekeruhan berkisarantara 173–749 NTU, kelimpahan fitoplankton rata-rata yaitu <302 ind/l dan spesiesfitoplankton yang ditemukan paling banyak dari kelas Bacillariophyceae yaitu 16spesies. Konsentrasi nitrat berkisar 0,0625 – 0,9431 mg/l, sementara konsetrasi fosfatberkisar dari 0,2131 – 0,3466 mg/l. Pengukuran kualitas perairan seperti kecepatanarus 0,85 m/dtk, kecerahan 16,6 cm, kedalaman 3,77 m, suhu 29,7 ºC, pH dengan 7-8,DO 5,4 mg/l dan salinitas 20 ppt. Berdasarkan hasil penelitian, tingkat kekeruhan sudahmelebihi baku mutu lingkungan air laut, sedangkan tingkat kesuburan perairantergolong rendah. Nilai produktivitas primer kotor menunjukkan bahwa lokasi penelitianini, fotosintesis masih dapat berlangsung dengna baik, namun respirasi yang dibutuhkanlebih besar daripada proses fotosintesis.
