Abstract

Environmental pollution that occurs in Tanjungpinang City, cannot be separated from the pollution of the aquatic ecosystem. Water pollution is caused by the presence of waste from residential activities, shops, industry, and other activities that produce waste. Likewise, what happens in the waters of the Sungai Jang, the activities of settlements, shops, industry can cause water pollution in this area, so a study is needed to see the extent of environmental pollution. The indicator used to determine the level of water pollution is by looking at the saprobity index through the phytoplankton community. This research was conducted by dividing the research stations based on differences in activity, namely; station 1 (settlements), station 2 (mangroves), station 3 (shops, industry), station 4 (reclamation). The results showed that the composition of the phytoplankton species found in the waters of the Sungai Jang, Tanjungpinang consisted of 17 species which were classified into 5 divisions. Diatomae types have the most number of species among other divisions, and the most dominating. The dominance of phytoplankton from the class Bacillariophyceae (Diatomae) cannot be separated from the role of nutrients in the water. The average saprobic index value of -0.39 is classified as Moderately Polluted (Meso Saprobik). Pollution that occurs is a result of organic waste from existing activities, causing an increase in nutrients. From the results of measurements in the field, the nutrient content (nitrate and phosphate) in the waters of the Sungai Jang had exceeded the quality standard.

Abstract

This study aims to determine the best feeding rate (FR) in increasing feed efficiency and growth of Chopped grouper and to determine the efficiency and growth of Chopped grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus). This research was conducted in February-March 2020 for 42 days at the Household Scale Hatchery of the Marin Agri Sejahtera Cooperative, Tanjungpinang City, Riau Islands. The method used was experimental with a completely randomized design (CRD) with 4 treatments and 3 replications where K treatment (15% trash feed), A treatment (10% trash feed), B treatment (20% trash feed), treatment C (feeding 25% trash feed). The results of the study, through statistical analysis, showed that the papain enzyme dose was able to have a very significant effect.

Abstract

This research aims to determine the effect of appropriate feeding time for the growth of Chopped Grouper Fish (Epinephelus fuscoguttatus x Epinephelus lanceolatus). This research was conducted from March to April 2020 for 42 days at Madong village, silver pompano culture group, Tanjungpinang City, Riau Islands Province. The methodology used in this research was experimental with a completely randomized design (CRD) with 3 treatments and 4 replications, which the T1: fed daily  T2: 1 day given food 1 day of fasting. T3: 2 days given food, 1 day of fasting. Analysis of the data using One-Way ANOVA showed that the best absolute weight growth was found in T1 treatment of (29.13 ± 1.07 g), daily growth (SGR) (0.69 ± 0.03 cm). The results obtained indicate that T1 treatment is the best treatment for growth

Abstract

Tourism Location of Guruh Gemurai Waterfall, Kuansing is one of the most beautiful tourist destinations to visit, which is located in Kuasing Regency, Riau. The study is conducted from September to October 2010. To see the sustainability of this tourist area, research was carried out to identify current environmental conditions. Factors for future development and assessing the ecotourism sustainability of Guruh Gemurai Waterfall using a survey. From the research results, it is found that many factors need to be improved by the management, especially those related to the safety of visitors, especially the stairs and handrails at level 4, the facilities besides being equipped with representative trash cans. It is recommended that the seven levels be managed, then all that is available must be developed again, both the damaged ones and the new ones, which must be remade so that it affects labor absorption. From the leveraging factors, there are six: covering the basic water substrate, water conditions, having protected species, local labor absorption, environmental knowledge, and growth in the number of traders. However, from these six leveraging factors, there are only three factors that can be improved, namely local labor absorption, environmental knowledge, and growth in the number of traders.

Abstract

In Bandar Alai Kari, Kuantan Tengah Sub-district, Kuantan Singingi Regency, Riau, there is a Buaya Lake. According to the history, the Buaya (crocodiles) Lake, used to be a place for river crocodiles to live (an area of approximately 4.5 ha). To obtain data on the value of the lake's conservation status (ecological value), a rapid assessment method is used using the ECELS index. Observations in the field and with the help of drones to observe the components of the ECELS index assessment, the index value is less than 30. From this value it can be concluded that the Bandar Alai Kari crocodile lake is in a very bad conservation status and needs to be restored

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.
