Abstract

AbstrakWaduk Wonorejo mendapatkan masukan air secara terus menerus dari Kali Wangi dengan membawa beban limbah dari aktivitas manusia, pertanian, pemukiman dan peternakan. Sehingga dapat memicu kesuburan perairan pada waduk. Kesuburan perairan dapat digambarkan dari nilai Produktivitas Primer yang selanjutnya berguna untuk mengestimasi produksi ikan yang berada di perairan tersebut. Tujuan dari penelitian tersebut adalah untuk mengidentifikasi pengaruh produktivitas primer perairan dan potensi ikan yang tertangkap di Waduk Wonorejo. Metode penelitian menggunakan metode observatorial dan penentuan kesuburan perairan menggunakan metode Tropic State Indeks. Kualitas air pada waduk didapatkan bahwa suhu berkisar 29-31oC, kecerahan berkisar 57,5-98,5 cm. Parameter kimia didapatkan pH berkisar 5-7, DO berkisar 6,21-10,03 mg/l, CO2  berkisar 3,9-18,97 mg/l, nitrat berkisar 0,54-1,6mg/l dan ortofosfat berkisar 0,005-0,168 mg/l. Nilai klorofil-a berkisar 2,76-16,1 mg/m3. Produktivitas primer 1,63-4,55 g C/m3/hari Nilai TSI berkisar 51,282-61,080. Kesimpulan bahwa kesuburan perairan di Waduk Wonorejo tergolong dalam perairan eutrofik berat dan potensi perikanan sebesar 3963,252 ton ikan/tahun. Hasil dari penelitian ini diharapkan dapat memberikan gambaran untuk acuan pengelolaan pemerintah setempat dan pengelola Waduk Wonorejo dalam mengelola Waduk Wonorejo agar berjalan secara tepat, berkesinambungan serta berkelanjutan.Keywords: Estimasi Potensi Ikan, Hipereutrofik, Kualitas Air, TSI AbstractWonorejo Reservoirs gets input water is constantly being from Kali Wangi with carrying burdens waste of human activities, agriculture, settlement and animal husbandry. So, that it can trigger fertility on reservoir waters. Water trophic levels can be described from the primary productivity and useful to estimate production of fish in these waters. The purpose of the research was to identify the influence of productivity primary waters and the potential fish are caught in Wonorejo Reservoirs. The methodology used observatorial methods and for water trophic level used Tropic State Index Method. Water quality in reservoir got the temperature ranges 29-31oC, Secchi disk range 57,5-98,5 cm. Chemical parameter obtained pH range, DO range 6,21-10,03 mg/l, CO2  range 3,9-18,97 mg/l, nitrat range 0,54-1,6mg/l and ortophospate range 0,005-0,168 mg/l. Chlorophyll-a values range 2,76-16,1 mg/m3. Primary Productivity 1,63-4,55 g C/m3/hari. TSI values range 51,282-61,080. The conclusion that water trophic level in Wonorejo Reservoirs are classified eutrofic heavy waters and fisheries potensial as much as 3963,252 ton fish/year. The results of the studied is expected to provide a reference to local government management and management Wonorejo Reservoirs in managing to appropriately , continuous and sustainable.Keywords: Hipereutrofic, Estimate of Potensial Fish, Water Quality, TSI

Abstract

Keberlanjutan kegiatan pertambakan sangat tergantung pada kondisi kualitas lingkungan perairan dalam mendukung potensi produksi biota budidaya. Namun, dalam pengelolaan juga perlu diketahui potensi lingkungan dalam memproduksi biota. Penelitian ini bertujuan untuk mengukur tingkat kesuburan perairan pada tambak serta mengestimasi produksi udang yang dihasilkan dengan pendekatan Produktivitas Primer. Penelitian dilakukan di tambak UPT Probolinggo, Fakultas Perikanan dan Ilmu Keluatan, Universitas Brawijaya. Analisis kesuburan perairan tambak dilakukan menggunakan metode Tropic State Index (TSI), dan pendugaan produksi udang dengan pendekatan metode Beveridge dengan mengkonversi nilai Produktivitas Primer, dimana nilai Produktivitas Primer dapat dihitung dengan mentransformasi nilai Klorofil-a. Rata-rata hasil pengukuran klorofil-a pada tambak 1 sebesar 23,06 mg/m3 dan pada tambak 2 sebesar 20,62 mg/m3. Tingkat kesuburan pada kedua tambak menunjukkan perairan eutrofik sedang. Rata-rata potensi produksi udang pada tambak 1 adalah 13,22 ton C-udang/2700m2/tahun; dan tambak 2 adalah 10,90 ton C-udang/2700m2/tahun. Korelasi antara nilai klorofil-a dan estimasi produksi udang menunjukkan nilai korelasi < 0,199 yang artinya keeratan kedua variabel sangat rendah. Namun korelasi antara klorofil-a dan PP memiliki hubungan yang sangat kuat yaitu > 0,99. The sustainability of aquaculture activities highly depends on the water quality conditions of the aquatic environment. Thus, determining the existing environmental condition of fish culture followed by regular monitoring is necessary to ensure the optimum production of farmed fish. The purpose of this current research was to determine the eutrophication level in shrimp ponds and estimate its shrimp production using the approach of Primary Productivity. The study was conducted in the shrimp ponds managed by the Probolinggo Technical Extension Office, Faculty of Fisheries and Marine Science, Brawijaya University. The eutrophication level was determined used the Tropic State Index (TSI) method. Shrimp production was estimated using the Beveridge Method by which the primary productivity values were calculated by transforming the Chlorophyll-a values. The results showed that the average contents of chlorophyll-a in pond 1 and pond 2 were 23.06 mg.m-3 and 20.62 mg.m-3, respectively. The eutrophication levels in both ponds indicate moderate eutrophic water. The estimated shrimp productions in ponds 1 and 2 were 13.22 and 10.90 tons C-shrimp 2700m-2 year-1, respectively. The correlation value between the chlorophyll-a levels and estimated shrimp productions was <0.199 which means that the relationship between the two variables is unsubtantial. On the other hand, the chlorophyll-a and primary productivity had a very strong relationship indicated by the correlation value of > 0.99.

Abstract

PKK (Family Welfare Empowerment) group in Ampeldento Village is a community group whose role needs to be increased, especially in improving family welfare. The problem they have is that the PKK group does not understand the potential of the narrow land owned by the family is the potential to increase family nutrition through the development of aquaponic cultivation systems. Therefore, carried out the implementation of community service programs through the development of the aquaponics system. Data collection techniques are done through interviews and questionnaires. Evaluation of community understanding of the program was carried out using pre-test and post-test. Based on the results of questionnaires and interviews before the program's implementation, it was found that 70% of respondents did not know aquaponics, 50% were not interested, 35% were hesitant in developing aquaponics independently and 45% doubted aquaponics could improve people's welfare. Results improved significantly after the program's implementation and were inversely proportional, with 95% of the community believing that aquaponics could improve welfare and 70% of respondents wanted to develop it independently. Respondents stated that vegetables produced are faster growing, tasty, green, nutritious and large.
