Abstract

A model of sustainable oil palm management in the tropical peatlands in Riau, precise and comprehensive data ofland and social economic farmers are required. The research has conducted in the Riau District four months by usingfield survey on land unit. The lands were had evaluated by maximum limiting factors and the socio-economic werecalculated by Multi-Dimensional Scaling. Oil palm development exist in the peatland affected on: 1) DHL score whichexceeds saturation level of 4 mS, and the highest score in Bengkalis 107,32 mS; 2) Land subsidence > 6 cm year-1especially Rokan Hilir have 18 cm year-1; 3) Change of ground water exceeding value float for oil palm (60 cm), highestvalue there was Siak 30-95 cm; 4) Level continue oil palm plantation in peatlands for the ecology dimension showedindex 47,35% (less have continuation) with ecology factor having an effect: water level, prevention of burning land,usage of amelioran /fertilization, and specific of site technology; 5) For social dimension showed index 55,65% (enoughhave continuation) with social factor having an effect: community empowerment, policy synchronization, solving of sosio-conflict, and weak of law straightening; 6) For economic dimension showed index 68,62% (enough have continuation)with economic factor having an effect: capital structure, price of fruit, and production equipments.

Abstract

The research was conducted in May 2014 in Medan Kota Belawan coastal waters. The aim of this research was to analyze the oil contents and diatom abundance as well as their correlation during high and low tide. Samples of sea water for oil and diatom analysis were collected from 4 stations. The analysis of oil content as well as identification and quantification of diatom were carried out in Marine Chemistry Laboratory, Faculty of Fisheries and Marine Sciences, University of Riau in Pekanbaru. The results of the study showed that the highest oil content was found during the high tide in Station 1 (0.322 ppm) and the lowest was at Station 4 (0.040 ppm). Diatoms that were found in the surface waters of Medan Kota Belawan coastal water comprising of 18 species. Nitzschia scrianata was the species with the highest abundance (3640.73 cells/l). The diatom abundance was found to be highest during high tide in Station 4 (1213.58 cells/l) and the lowest was during low tide in Station 1 (360.80 cells/l). Oil content with diatom abundance showed a weak negative correlation (Y = 639,7-971,1x ; R2 = 0.146 ; r = 0.382) at high tide while at low tide Y = 520.7-1370.0x ; R2 = 0.115 ; r = 0.339 which mean that increasing oil content will decrease the abundance of diatoms in Medan Kota Belawan coastal waters.Keywords : Belawan Coastal Waters, oil, diatoms and tide

Abstract

This research was conducted in June 2015 with the aim was to knowing the concentration of heavy metals of Pb, Cu and Zn accumulated in the albumen and yolk of olive ridley sea turtle (Lepidochelys olivacea) from Pariaman town beach, West Sumatra Province. The method used was a survey conducted on 3 beaches. The results showed that the average metal Pb in albumen (2.7644 μg/g) was greater than the metal Cu (2.0970 μg/g) and smaller than the metal Zn (10.4924 μg/g). While metal Pb in yolk (6.8008 μg/g) was smaller than the metal Cu (7.0357 μg/g) and metal Zn (34.1479 μg/g). The PTWI calculation value (the Provisional Torelable Weekly Intake) based on FAO/WHO standard for an adult weighing of 70 kg told that the eggs were still reasonably consumtable as long as it did not exceed the limit of 3.2932 kg/week for Pb, 482.8780 kg/week for Cu and 197.5793 kg/week for Zn. However, consumsing turtle eggs continuously can harm the body’s health and threaten the sustainability of turtles in the wild.

Abstract

This study was conducted in July 2015 with the aim to observe the macrozoobenthospopulation and organic matter content in the sediment. The samples were collected from HurunBay in Lampung Province with using survey method. Samples were analyzed in the Laboratoryof Water Quality BBPPL Lampung and Chemistry Laboratory, Faculty of Fisheries and MarineSciences University of Riau. The study showed that the organic content in the sediment between22.88 - 54.91%, while the abundance of macrozoobenthos was between 20.29 - 66.67 ind / m2.Macrozoobenthos identified in Hurun Bay 8 species, 3 classes and 2 phylua. From the phylum ofMollusca there were Gastropod i.e. which had 5 species and from the classes of bivalves thestudy also found two species. From the phylum annelid there was one class, Polychaeta and onespecies, i.e. Nereis sp. The relationship between macrozoobenthos and organic content wasexpressed with the equation of Y = 9,411 + 0,6268X that the relationship of organic matter withmacrozoobenthos abundance was weak.Keywords: Lampung, sediment, organic, makrozoobenthos

Abstract

This research was conducted in September 2015 in the coastal waters of Belakang Padang, Batam Riau Archipelago Province to analyze the concentration of oil in the water and sediment, the difference and the relationship between oil concentration in the water and in the sediment. Water samples were taken by using sample bottles and sediment samples were taken by using Ekman grab from 15 sampling sites, and then they were analyzed in the Marine Chemistry Laboratory University of Riau. The highest concentration in the water was found in Station 2 (0.1823 ppm) and the lowest in Station 3 (0,1328ppm). The highest oil concentration in the sediment was in Station 2 (286 ppm) and the lowest in Station 3 (130 ppm). The concentration of oil in the sediment were higher than in water. Oil concentration in the water and in sediment has weak relationship and negatively correlated. Characteristics of the sediment in the sampling sites was dominated by sand fraction.   Key words :Oil, Sediment, Water, Batam

Abstract

This research was conducted in February to March 2017 in Dumai River estuary of Riau Province, with the aim to find out if there is any differences the total organic matter content and the abundance of phytoplankton between stations, and the relationship between total organic matter with the abundance of phytoplankton. The method used is a survey method consisting of 4 stations with 3 replications at each station. Based on the results, the highest average total organic content was found in Station 1 (24,01 mg/L) and lowest was at Station 3 (7,37 mg/L). There is a difference of total organic matter content between stations. There are 8 types of phytoplankton that found on the surface waters of the Dumai River estuary, where the most dominant type is Isthmia sp. The highest abundance of phytoplankton was found at Station 4 (4443,98 ind/L), and the lowest was at Station 2 (1367,41 ind/L). There was no difference in abundance of phytoplankton between stations. The relationship of total organic matter content with phytoplankton abundance shows a moderate negative relationship, which means that the increasing of total organic matter content will decrease the abundance of phytoplankton in the waters of Dumai River estuary.Keywords: Dumai River Estuary, Abudance of Phytoplankton, Total Organic Matter
