“…Beberapa sungai besar (sungai Badung, sungai Mati dan sungai Sama) bermuara di Teluk Benoa serta pada Teluk Benoa terdapat Taman Hutan Raya Ngurah Rai (Rachman et al, 2016). Teluk Benoa dikelilingi oleh hutan mangrove dan berbatasan dengan Semenanjung Jimbaran di sebelah barat serta Tanjung Benoa dan Pulau Serangan di sebelah timur (Karang, 2016).…”

The growth aspect is important in determining fish well-being in an area. However, research on the growth aspect of Ambassis macracanthus Bleeker, 1849, in Ngurah Rai Forest Park has never been conducted This study aims to determine the length-weight relationship and condition factor of A. macracanthus as well as to evaluate the water condition in Ngurah Rai Forest Park, Benoa Bay during the east season. The sample was collected applying descriptive and quantitative methods, whilst the purposive sampling method was used to take the samples from three stations using Bubu and experimental gill net. During the sampling collection process, 304 fish individuals were caught by the experimental gill net at station 1 (Serangan waters). Based on the analysis between the length and weight relationship of A. macracanthus, the equation of W=0,024L2.38, where from this equation, the value of b = 2.38 is obtained. Through the T-test, the value of b < 3 showed a negative allometric growth pattern; namely, the growth in length is more dominant than the increase in weight. The average relative condition factor increased monthly, with the highest value of 1.37 in August. However, the value of the relative condition factor indicates that the fish in Tahura waters are thin (Kn < 2). In general, the temperature and dissolved oxygen of Ngurah Rai Forest Park waters are not following quality standards.

“…Satelite dengan sensor optic merupakan teknologi terkini untuk mengukur atau merekam karakteristik permukaan bumi berdasarkan perbedaan nilai spectral. Ekstraksi informasi sprektral dari citra satellite penting sebaga database optic yang akan membantu dalam memamahi suatu perairan (Karang, 2016). Metode dalam penelitian ini menggunakan citra satelit landsat 8 dan data insitu.…”

Total suspended solid is a suspended solid that causes turbidity in the waters. These particles cannot settle directly on the bottom of the water. TSS size and weight are smaller than sediment. TSS concentration if too high will inhibit the penetration of light into the water and result in disruption of photosynthesis. The number of human activities around the waters of Benoa Bay can produce pollutant waste into the waters which can cause negative impacts on the conditions of marine life. This TSS value is one part that plays a role in determining the environmental quality of a waters. Seeing the input from the rivers which empties into Benoa Bay, the need for research in the Benoa Bay area is related to total suspended solids. Technological developments, especially in remote sensing, make the implementation of mapping the distribution of TSS concentrations efficient. The method in this study used Landsat 8 satellite images and in situ data. This research was conducted in May 2018. The research location consisted of 30 points by purposive sampling. The TSS concentration value in situ has an average concentration of 301.65 mg / L. Middle waters have greater concentration because this is due to the effects of tides. TSS concentration values from images can be calculated using the Budhiman, Guzman and Parvati algorithms. The results of the calculation of the three algorithms have an error value above 30%. This may be due to differences in water conditions which result in differences in concentration from the insitu value and the value of satellite images in the waters of Benoa Bay.

“…Teluk Benoa merupakan salah satu estuari yang secara administratif terletak di Kabupaten Badung dan Kota Denpasar, Provinsi Bali dengan luas perairan teluk sekitar 1.998,1 Ha (Sudiarta dkk., 2013). Pada kawasan ini terdapat keanekaragaman ekosistem yaitu ekosistem mangrove, padang lamun, terumbu karang dan dataran pasang surut (Wiyanto dan Faiqoh, 2015;Faiqoh dkk., 2016;Karang, 2016). Teluk Benoa merupakan ekosistem estuari dangkal, dimana sejumlah sungai bermuara di perairan Teluk Benoa.…”

Benoa Bay is an estuary that effected by pollutan from river and human activity. Reasearch on spatial and temporal distribution of nitrate and phosphate has been conducted in Benoa Bay. Data was collected at water surface during ebb from December 2016 to Februari 2017. There were19 Sampling pointlocated in Benoa Bay and 6 pointslocated in rivers around Benoa Bay. Nitrate was analysed using Brucine method and phosphate was analysed using Amm-Molybdat method. The concentration of nitrate from December 2016 to February 2017 ranged from 0,036 mg/L to 1,154 mg/L and the concentration of phosphate ranged from undetectedto 0,739 mg/L. The concentration of nitrate at rivers ranged from undetectedto 3,584 mg/L andthe concentration of phosphate ranged from undetectedto2,405 mg/L. The concentration of nitrate and phosphate from December 2016 to February 2017 was fluctuating and the highest average concentration of nitrat and phosphate was found in February 2017. These was due to high rainfall in February 2017 and cause a lot of organic matters carried by the rivers into Benoa Bay. The highest distribution concentration of nitrate and phosphate was found around estuary. These due to input of organic matters from mainland through the rivers. Based on water quality standards of Bali Goverment, the concentration of nitrate and phosphate was exceeds the seawater quality standart.
