PERTUMBUHAN, PRODUKSI BIOMASSA DAN KANDUNGAN KARAGINAN RUMPUT LAUT Kappaphycus alvarezii DENGAN BERBAGAI METODE BUDIDAYA DI DALAM EKOSISTEM PADANG LAMUN
No full textPenelitian bertujuan menentukan metode budidaya yang tepat yang menghasilkan pertumbuhan, produksi biomassa dan kandungan karaginan yang maksimal di dalam ekosistem padang lamun. Penelitian dilaksanakan pada bulan Maret sampai Juni 2011 di perairan Dusun Puntondo, Desa Laikang, Kecamatan Mangarabombang, Kabupaten Takalar, Sulawesi Selatan. Analisis kandungan karaginan rumput laut dan parameter kimia kualitas air dilakukan di Laboratorium Kualitas Air, Jurusan Perikanan, Fakultas Ilmu Kelautan dan Perikanan, Universitas Hasanuddin. Metode budidaya yang diterapkan sebagai perlakuan yaitu permukaan (20 cm di bawah permukaan air), metode lepas dasar (kedalaman 100 cm), dan metode dasar (pada sedimen dasar). Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) masing-masing 5 ulangan untuk setiap perlakuan. Data laju pertumbuhan dan produksi biomassa dianalisis dengan Analisis Ragam dilanjutkan dengan uji Tukey, sedangkan parameter kualitas air dianalisis secara deskriptif berdasarkan kelayakan hidup untuk rumput laut K. alvarezii. Hasil penelitian menunjukkan bahwa laju pertumbuhan harian, produksi biomassa dan kandungan karaginan tertinggi dihasilkan metode lepas dasar yakni masing-masing 1,54%/hari, 182,2 g dan 44,8%, sedangkan terendah metode dasar masing-masing 1,14%/hari, 124,4 g dan 39,9%. Hal ini disebabkan oleh intensitas cahaya matahari yang ditrerima oleh rumput laut pada lapisan air di atas dasar perairan (metode lepas dasar) optimal untuk metabolisme (proses fotosintesis dan penyerapan zat-zat hara berupa NH4+, NO3+, PO4- dan dan CO2). Pada metode dasar, intensitas cahaya rendah, sehingga penyerapan unsur hara dan proses fotosintesis agak terhambat, berakibat pada laju pertumbuhan, produksi biomassa, dan kandungan karaginan rendah, meskipun kandungan unsur hara pada dasar perairan cukup tinggi. Dekomposisi yang intensitf dari tallus oleh bakteri pada dasar perairan merupakan faktor lain penyebab rendahnya laju pertumbuhan, produksi biomassa dan kandungan karaginan rumput laut tersebut. Seluruh parameter kualitas air yang terukur berada pada kisaran yang optimal bagi pertumbuhan rumput laut

THE IMPACT OF SEAWEED FARMING ON THE PHYTOPLANKTON COMMUNITY STRUCTURE
No full textThis study was aimed to analyze the impact of seaweed farming on changes in the structure of phytoplankton communities on various ecosystems and their relationship with environmental factors. The study was conducted in May-October 2017 in the waters of Karampuang Island, Mamuju Regency. Plankton samples were collectedfromthreecultivationareas, namely areas with sandy bottom (control), seagrass beds, and coral reefs. In each area, three media were placed with a longline system, size 40 x 30 m2 (as replication). Sampling was carried out at the beginning before initiation of the cultivation and every two weeks after cultivation was started for 42 days. Phytoplankton sampling and measurement of environmental factors were carried out at fivesamplingpoints representing the cultivation areas. In sandy areas, sampling was also applied in areas outside the cultivation at a distance of 25m and 50m. Variance analysis was used to analyze differences in the species number and abundance of phytoplankton. Ecological indices was used to test phytoplankton biodiversity. PCA was used to analyze its relationship with environmental factors. Differences in the species number and abundance of phytoplankton between farming areas according to temporal scale were found. The high number and speciesabundance of phytoplankton were found in seagrass areas and significantly different from coral reefs and sandy area. Seaweed farming at the beginning of the farming period showed a positive impact by increasing the number of species and abundance of phytoplankton, but then decreased after entering Week 4-Week 6, along with the occurrence of ice-ice disease on the seaweed. Diversity index value was classified as medium with high equality without the dominance of particular species. The high number of species and abundance of phytoplankton occured at second weeks in all cultivation areas which are characterized by abundance of zooplankton with environmental characteristics, i.e. high DO and low PO4, NO3, andDOM

No full textEnvironmental pollution in the form of organic waste containing nitrogen (N) and phosphate (P) sourced from superintensive shrimp pond cultivation due to much feed use is a severe problem in the development of superintensive technology in Indonesia. This study aims (1) to estimate the amount of feed wasted into the environment during cultivation in superintensive ponds and (2) estimate the amount of N and P waste that is wasted into the environment from superintensive cultivation. The research method is carried out in 3 stages; the first stage was carried out on a superintensive pond for 76 days by carrying out superintensive shrimp farming with a density of 600 tails / m2 then carried out observations of wasted feed. The second stage is to conduct laboratory-scale shrimp digestibility tests, and the third stage is laboratory-scale shrimp excretion research. The results showed that (1) the amount of feed wasted into the environment (un-eaten) amounted to 24.32% of the total feed provided. The burden of organic waste from superintensive ponds shrimp discharged into the waters of Labuange Bay is 3.89 tons/year consisting of organic waste containing N amounting to 3.61 tons/year with a mean of discharging to waters of 10.31 kg/day, and organic waste containing P of 0.28 tons/year with a mean discharge to the waters of 0.81 kg/day. These results indicate that the waters of Labuange Bay have experienced the pressure of organic waste originating from superintensive shrimp pond activities.Pencemaran lingkungan oleh limbah organik mengandung nitrogen (N) dan fosfat (P) yang bersumber dari tambak udang superintensif karena penggunaan pakan yang banyak merupakan masalah serius dalam pengembangan teknologi superintensif di Indonesia.
