Primary Productivity on Abandoned Bauxite Mining Pits of Tanjungpinang City, Riau Islands. The abandoned bauxite mining pits in Bintan Island have a good opportunity to be developed, especially as an aquaculture area. The objective of this study was to determine the primary productivity of the waters, phytoplankton ecological index, and physical and chemical parameters of the bauxite post-mining ponds in Tanjungpinang City, Riau Islands. The study was conducted in April-August 2018 in two bauxite post-mining ponds (station 1 and 2) in Senggarang, Tanjungpinang City. The parameters observed were the abundance and ecological index of phytoplankton, aquatic primary productivity, physical and chemical parameters of the waters, and nutrients, N and P. From the study it was found that there were three phytoplankton divisions, consisted of three classes and eight genera. Mougeotia sp. was the dominant species of phytoplankton. The abandoned bauxite mining pits were classified as labile and the phytoplankton communities were under environmental stress due to the dominance of certain species. The abandoned bauxite mining pits were classified as young (inundation <5 years), low primary productivity, as well as oligotrophic waters. Net primary productivity in station 2 was higher than station 1, i.e. 1,23 mgC L-1 day-1 and 0,25 mgC L-1 day-1, respectively. The physical and chemical parameters of the bauxite post-mining ponds studied met the quality standards for freshwater aquaculture activities, except for pH and ammonia.

The development of aquaculture in the Marine Protected Area (KKP) has to recognize the sustainability and the balancing of the ecosystem in that area. It causes limited rights of users who want to develop their business, where the issuance of permits and business management regulations is an obligation that must be followed by aquaculture business developers in the KKP area. The study aimed was to formulate the technical directions in developing the potential for aquaculture business in the Marine Protected Area of Datok Bandar (KKPD) at Lingga Regency. The method used in this research is a descriptive quantitative using analysis of the carrying capacity of the environment for aquaculture, water quality parameters, and a participatory approach. The results showed that the potential area to be developed for aquaculture was 3,736.01 ha. However, based on the carrying capacity analysis, only 268,420 ha or 7.2% from the existing potential can be utilized for aquaculture. Furthermore, based on the water quality measurements for aquaculture, the KKPD area was divided into 3 designations groups of aquaculture areas, namely the KJT, KJA, and seaweed. The number of aquaculture business units that were allowed in this area was 16,776 units consisting of 10,066 small business units and 6,710 medium business units with 7 types of superior fish. The limitation of land area and some business units in conservation areas were important to ensure the sustainability of the environment in the future. The implication of this research could be used as a basis for issuing aquaculture business permits, and to ensure that small-scale aquaculture fishermen have a large proportion. In addition to ensuring the existence of local communities who were generally small farmers, conservation areas were very vulnerable to environmental changes, so the risk factors and impacts of business utilization were important to consider.

Mangrove ecosystems have functions and benefits that are quite important both physically and biologically. Mangroves can act as natural coastal protectors from damage due to abrasion and large waves and also provide shelter for associated biota. Development of a mangrove ecosystem that can be developed into a tourism area and an environmental-based education center. Pengudang Village has the potential to be developed into a mangrove ecotourism area with its resources and biodiversity. Development into a mangrove ecotourism area is constrained by public understanding of the types of mangroves, benefits and associated biota in the mangrove ecosystem of Pengudang Village. Community service activities carried out aim to provide understanding to the Pengudang Village community about the potential and types of mangrove resources and associated biota. The activity process begins with a survey of the potential of the mangrove ecosystem including recording, identification, and classification of mangrove species. The introduction and socialization of the condition of the man-grove ecosystem was carried out to the coastal community of Pengudang Village. From the results of field identification, it was found that the mangrove condition of Pengudang Village is in good condition with a dense density. Associated biota in mangrove ecosystems vary from gastropods to mammals. The identification results are disseminated to the Pengudang Village community.
