| Abstract: | Penelitian ini dilaksanakan di Perairan Teluk Kendari pada bulan April – Juni 2009 dengan menempatkan 3 stasiun penelitian. Tujuan penelitian adalah mengkaji hubungan antara produktivitas primer fitoplankton dengan kelimpahan dan biomassa fitoplankton, serta hubungan antara produktivitas primer fitoplankton dengan ketersediaan unsur hara dan intensitas cahaya pada berbagai tingkat kecerahan di perairan Teluk Kendari. Hasil penelitian menunjukkan bahwa nilai produktivitas primer selama penelitian pada perairan Teluk Kendari yaitu pada stasiun luar teluk berkisar 2,54-8,98 mgC/m3/jam, pada stasiun tengah teluk 2,77-11,13 mgC/m3/jam, dan 3,33-9,19 mgC/m3/jam pada stasiun dalam teluk. Hubungan produktivitas primer fitoplankton dengan unsur hara dan intensitas cahaya memperlihatkan keeratan hubungan yang tinggi pada ketiga stasiun penelitian. Ketiga stasiun penelitian menunjukkan pola yang hampir sama antara ketiga stasiun penelitian. Pada stasiun luar teluk, ketiga unsur hara N (amonia, nitrat, dan nitrit) dan intensitas cahaya menjadi faktor yang memberikan pengaruh nyata terhadap tinggi dan rendahnya nilai NPP, sedang pada stasiun tengah dan dalam teluk, unsur hara nitrat bersama ICM memberikan pengaruh yang nyata terhadap tinggi dan rendahnya nilai NPP di perairan. The relationship between primary productivity of phytoplankton to the availability of nutrients in the waters of the Bay of Kendari was implemented on April-June 2009 at three sites. The purpose of this research is to examine the relationship between primary productivity of phytoplankton with the abundance and biomass of phytoplankton, and the relationship between primary productivity of phytoplankton with nutrient availability and light intensity at various levels of brightness in the waters of the Bay of Kendari. Based on the data description and laboratory analysis, net primary productivity values during the survey period varied from 2,54 to 11,13 mgC/m3/hour with ranges of average value of NPP from 5,10 to 7,30 mgC/m3/hour. Sampling station located at the middle of the bay had the highest NPP value followed by sampling station positioned at the mouth of the bay and the lowest was found at sampling station located near the river mouth of the upper part of the bay. Relationship between primary productivity and sunlight intensity depicted a strong correlation at the three sampling stations. Relationship of primary productivity to nutrient and light intensity showed that the relationship high on all three stations. The three stations showed similar patterns between the three research stations. At the station mouth of the bay, the three nutrients N (ammonia, nitrate, and nitrite) and light intensity are also factors that provide a real influence on the high and low NPP values while at the middle station and inside the bay, nutrient nitrate with ICM provides a real influence against high and low NPP values in the waters. |
