Abstract

Goniopora stokesi coral is one of the massive corals on Laelae Island and Barranglompo Island. Massive coral growth in the formation of coral skeleton sedimentation rate (CaCO3) is highly dependent on the environment. The research objective was to analyze the differences in the growth rates of G. stokesi, as well as the relationship between environmental factors and the growth rates of G. stokesi corals in Laelae Island and Barranglompo Island. This study uses secondary data on coral growth of G. stokesi and data on environmental conditions from 2009 to 2013, in the waters of Laelae Island and Barranglompo Island. Differences in coral growth rates were analyzed using One Way ANOVA analysis, if there were significant differences followed by a significant difference test according to the Bonferroni method, with SPSS 19.00 software. Analysis of the relationship between environmental factors and coral growth using the Principle Component Analysis (PCA) test with Microsoft Excel 2003 software. The results showed that the environmental conditions in the waters of Laelae Island and Barranglompo Island showed a range of values that were not too different, only the traffic, current, and turbidity values were different between the two islands. The coral growth rate of G. stokesi on Laelae Island was 9.72 ± 1.16 mm year-1, while on Barranglompo Island it was 12.47 ± 2.67 mm year-1. The coral growth of G. stokesi on Laelae Island was affected by high currents and turbidity, while on Barranglompo Island it was influenced by high salinity.

Abstract

Intensive agricultural practices in the upper land of the Indragiri river bring about problem to  oxbow-lakes spreading out along in the middle and downstream of the river. Danau Sungai Sorik (DSL) typically included to oxbow-lake, situated in the middle part of Indragiri River, one of four big river in Riau Province, Sumatera. Since the catchment area of the lake were totally urban, accordingly the dynamic equilibrium of lake ecosystem were shifted. The lakes were reportedly degraded in terms of hydrological regime, high sedimentation, fully vegetated and low biological diversity. The local government has repeatedly normalized the depth of the lake in related to development of water attraction, restocking of invading species of fish, cage culture and rice field along the edge of the lake. The present papers aimed at characterizing and assessment of physicochemical and biological properties of the water. Further, potential threats on the sustainability of the lake were assessed. Based on chemical properties of water including BOD5, phosphate and Nitrate range were of (3.26-7.43), (0.11-0.13) and (0.229-0.433) m/L, respectively, were categorized into un-equilibrium or slightly polluted. The water transparency appeared low (25-29) cm, the pH of 6.0-6.5) and temperature of 31-32 0C. Apparently, the diversity index (H), dominancy index and similarity index of phytoplankton ranged from (0.9110-1.2211), (0.3201-0.6136) and (0.3939-0.6290, respectively. It suggested slightly dominated by certain species

Abstract

Longtail Shad are endemic in the waters of Riau and especially in the waters of Bengkalis Regency and have omnivore characteristics, namely eating plants and also from groups of animals. The purpose of this study is whether fish is the best in choosing food depending on the type of food or not. This study uses a survey method, which was conducted in Bengkalis waters from May to June 2019. In this study, it was shown that fish is the best in choosing food depending on the type of food available (selective), so that if the type of animal, in this case, is crustacean and crab. There are a lot of small crabs, then the worst fish eat the group of crustaceans and small crabs. However, if what is available is only from the algae group, the best fish will only eat from the algae group. So that in the stomach of the Longtail Shad are not found both types of food at once

Abstract

Heavy metals in soil are relatively easy to be degraded by using plants. Certain plants have a high potency to bioaccumulate heavy metals and to be hyperaccumulator by translocating the high concentrated metals from soil into plant tissues without  causing a negative effect to the plants. One of the potential plants is a flat leave Sansevieria, which is relative easy and fast to grow.The research was conducted to evaluate the potency of five flat leave Sanseviera: S. indica “Tiger Blue”, S. trifasciata “Lorentii”, S. aubrytiana “Tiger Strip”, S. kirkii “Coopertone” and S. hybrid “Blue Boy” as the treatment, and was replicated three times. Each replicate consisted of five plants, which were pre-selected from 100 grown plants. Heavy metals (Pb, Cd, Cu and Zn) in the growing media (soil) and plant tissues were analyzed by using Atomic Absorbtion Spectophotometric (AAS). The results indicated that : 1). Pb, Cd, Cu and Zn concentration in growing media (soils) were in a normal range, 2). S. indica “Tiger Blue” had the highest bioaccumulation potency to Cu and high potency to Cd, Zn and Pb. S. trifasciata “Laurentii” had the highest bioaccumulation potency to Cu and high potency to Cd and Pb, 3). S. indica “Tiger Blue” had the highest hyperaccumulator  potency to Cu and high potency to Cd. S. trifasciata “Laurentii” had the highest hyperaccumulator potency to Cu and high potency to Pb.

Abstract

Pelalawan District has several sleep peatland areas, which overgrown with grass weeds. This area has the potential to become a sources of beef cattle farming feed in the intensive livestock system. The potential of the beef cattle market is still prospective as a source of protein demanded by the majority peoples. This study aims to valuate and evaluate the potential carrying capacity and economic value of sleep peatlands area as forage provider. This research method was descriptive approach. The data used in this study is secondary data collected from various reliable sources and previous related research. Carrying capacity was expressed by estimate the land's ability to provide cattle feed. Economic analysis is carried out by estimate profit which obtained from the intensive beef cattle farming system. The analysis results shows that sleep peatland areas that potential to supports intensive beef cattle farming around 3,210 ha with carrying capacity = 9,078 cows/year. This carrying capacity was higher than the current beef cattle population around 1,992 cows. The potential economic value reaches IDR 45.56 B/year, which is higher than the current actual economic around IDR 9.99 B. It’s necessary to improve management aspects by integrating the development of intensive cattle farming systems with community-based peatland restoration programs, corporate social responsibility, and SDGs achievement commitments. This requires a solid partnership among stakeholders that will increase the management dimension towards a more sustainable way.

Abstract

The former mining area in Tanjungpinang City was found around the Carang River and Senggarang Village. There was sedimentation containing red mud from the rest of the mining activities that covered the mangrove substrate. The impact is expected to affect the life of the surrounding mangroves. One of the dominant species found is Avicennia marina. This study aims to determine the absorption ability of heavy metal A. marina found around the former bauxite mining area of Tanjungpinang City. The study was conducted from April to August 2020. The study was conducted by a survey by sampling the sediment around the A. marina tree and its organs (roots, stems, and leaves) in the laboratory using the Atomic Absorption Spectrophotometer (AAS). The results of the analysis showed that the concentration of Pb in the sediment ranged from 0.2215-0.2711 ppm; Cd concentration ranged from 0.0113-0.0721 ppm; and Cr ranged from 0.0221-0.0633 ppm. The highest average metal concentration value for Pb was in the Carang River (root organ with a value of 2.1691 ppm); Cd metal in Senggarang (stem, 0.0951 ppm); and Cr metal in Senggarang (root, 0.4988 ppm). The phytoaccumulation mechanism of Pb, Cr, and Cd by A. marina is rhizofiltration (TF<1), while the BCF value indicates that A. marina is non-accumulator/low accumulator (BCF < 250 ppm).
