STRUKTUR DEMOGRAFI POPULASI Rhizophora apiculata DI KAWASAN INDUSTRI PERMINYAKAN PROVINSI RIAU

The decline in mangrove vegetation density and the area of mangrove forests in the coastal province of Riau occurred due to the logging of mangrove forests and the conversion of mangrove forests into other uses such as industrial estates. This study aims to collect a database of mangrove ecosystems which includes the ecological structure of R. apiculata in Riau Province. Collecting data of mangrove vegetation condition was done by transect line and plot. The line transect was drawn from the reference point (the outer mangrove stand) with the direction perpendicular to the coastline to the mainland and made plots according to the category. The results showed that the population of R. apiculata was found in large numbers at Station 3 (350 ind) and a small/small amount was found at Station 1 (137 ind). In addition, Stations 1, 2 and 4 have only one grouping population of R. apiculata based on the Bhattacharya method, while Station 3 has two groupings. Furthermore, the highest R. apiculata density for tree category was obtained at Station 4 (1433.33 ind/m2), saplings category at Station 3 (10488.89 ind/m2) and seedlings category at Station 4 (3666667 ind/m2). Furthermore the water temperature ranged from 28.3 – 30.7°C, salinity 27.3 – 31.3, pH 7.3 – 7.9, DO 5.2 – 6.4 and redox potential ranged from 102 – 124 mV. Based on the standard criteria and guidelines for determining mangrove damage according to the Decree of the Minister of Environment No. 201 of 2004, the population density of R. apiculata at the research location is still classified as medium and refers to the Decree of the State Minister of Environment No. 51 of 2004 concerning Sea Water Quality Standards for Marine Biota, as a whole the range of measured water quality parameters is still within tolerance limits for life mangroves.

Mangrove forests now face serious threats, where human anthropogenic pressure has increased rapidly in coastal areas around mangrove areas. The ecological study of the waters of Tunda Serang Banten Island, especially the general condition of its mangrove forests, was carried out in January 2014. This was intended as a baseline in evaluating mangrove management in Indonesia (especially Tunda Serang Banten Island) and the presence of Indonesian mangrove forests could be maintained in the future. Data on the condition of the mangrove vegetation of Tunda Serang Banten Island was collected by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland. While the measurement of water quality is done in-situ. The results showed that the growth of the mangrove forest of Tunda Serang Island in Banten on the East (Station 1) was younger than that in the South (Station 2). Then the density is also higher in the East than in the South, but the condition of the mangrove forests of both stations is still relatively good and very dense. In addition, the environmental quality of Tunda Island's mangrove vegetation is still relatively high, the diversity and dominance of mangrove forests is low, uniformity in a somewhat balanced condition, regular distribution patterns and water quality parameters are not a barrier to the growth of mangroves.

Taman Nasional Sembilang merupakan salah satu taman nasional yang terletak di Sumatera Selatan dan menjadi kawasan mangrove terbesar di barat Indonesia. Sebagian besar wilayah mangrovenya telah mengalami alih fungsi menjadi tambak pasang surut. Hal ini menyebabkan timbulnya kekhawatiran kerusakan mangrove di taman nasional. Salah satu upaya untuk mempertahankan wilayah mangrove adalah dengan melakukan sistem silvofishery, yaitu penanaman mangrove dan budidaya bandeng dilakukan secara bersamaan di tambak. Penelitian ini bertujuan untuk menganalisis kualitas air dan kondisi nutrien di tambak di daerah restorasi silvofishery di Taman Nasional Sembilang. Penelitian dilakukan dengan metode purposive sampling di tambak silvofishery, tambak non-silvofishery, dan badan air sungai di seluruh wilayah taman nasional. Pengukuran dilakukan terhadap parameter kualitas air dan kandungan nutrien khususnya nitrat dan fosfat. Hasil penelitian menunjukkan bahwa kehadiran tanaman mangrove di daerah tambak mampu memperbaiki kandungan oksigen dan pH air tambak. Mangrove juga menunjukkan kemampuan dalam mengikat nitrat yang secara tidak langsung akan mencegah air tambak dari polusi. Namun, kandungan fosfat tinggi menunjukkan bahwa tanaman mangrove muda di wilayah restorasi belum mampu mengikat nutrien ini secara signifikan. Hasil penelitian ini menunjukkan bahwa hutan mangrove sangat bermanfaat bagi kegiatan budidaya tambak karena kemampuannya dalam menyerap polutan nutrient. Kata kunci: silvofishery; kolam; nitrat; fosfat; Taman Nasional Sembilang Sembilang National Park is one of the national parks which is located in South Sumatera and became the largest mangrove area in western Indonesia. Most of the mangroves area in this national park has been experiencing conversion to be tidal ponds. This has resulted in concerns on mangrove forest destruction in the park. One of the efforts to maintain mangroves area is by applying silvofishery system, which is mangrove planting and cultivation of milkfish in ponds performed simultaneously. This study aims to investigate the water quality and nutrient condition in the ponds in the area of silvofishery restoration at Sembilang National Park. The study was conducted by purposive sampling method in the silvofishery ponds, non-silvofishery ponds, and river water bodies throughout the park. Measurements conducted on water quality parameters and nutrient content, especially nitrate and phosphate. The results showed that the presence of mangrove in the ponds area is able to improve the oxygen content and pH of pond water. Mangroves also demonstrated the ability to bind nitrates which indirectly will prevent the pond water from pollution. However, the high phosphorus content showed that young mangrove plants in the restoration area have not been able to significantly bind the of this nutrient. The results of this study showed that mangrove forests are very beneficial for aquaculture activities because of its ability to absorb nutrient pollutants.

Crab Density

Rehabilitation of mangrove forests is very important to maintain ecosystem stability and increase the productivity of mangrove forests. The success of mangrove forest rehabilitation can be seen by the density of mangrove vegetation and the increase in mangrove crabs. Mangrove crab is the main commodity for farming communities because in addition to playing an important role in the mangrove ecosystem, it also has high economic value so it needs to be developed to increase people's income. This research was conducted with the aim of knowing the density of mangrove vegetation and crab density in different planting years and the effect of mangrove habitat characteristics on crab density. The research was conducted in three different planting years, namely 2003, 2005, and 2006. Each planting year consisted of a front zone, a middle zone and a back zone. In each zone a measuring plot with a size of 5 m x 5 m was made to collect data on vegetation density, temperature, mud thickness, salinity, acidity, and dissolved oxygen (DO). Then in the 5 m x 5 m plot, a 1 m x 1 m plot was made to collect data on the number of crabs. Data analysis used regression equation and ANOVA difference test. The results showed that the highest vegetation density was in the back zone of the 2006 planting year with a density of 2160 individuals/ha, while the highest density of crabs was in the 2005 planting year with a density of 12111.11 individuals/ha. Regression analysis showed the effect of temperature, mud thickness and salinity variables on crab density with the equation Y = 3.447 - 0.044X1 - 0.009X2 - 0.230X3 with R = 0.809. In the different ANOVA test, only the thickness of the mud had a significant difference at three years of planting (0.00 < 0.05).
