Abstract

Water quality plays an important role in aquaponics system. Water chemistry parameter that may affect water quality is total organic carbon. Sources of carbon in the aquaponics system mainly derived from the decomposition of organic matter which derived from artificial feed and plant respiration. The research was conducted to study the reduction of total organic carbon concentration in the aquaponic system and the relation of abundance and diversity of phytoplankton. This research using different amount of ipomoea (Ipomoea aquatica) consist of 10, 20, and 30 rods and control treatments which use without ipomoea. The results showed that all of ipomoea treatments can reduce the amount of total organic carbon concentration in the aquaponics system. This research showed that nutrients cycle in the aquaponics system, especially total organic carbon dissolved in water is influenced by many factors such as plants, fish and primary productivity which determined by the plankton. Furthermore, a positive correlation occurred between total organic carbon concentration of the abundance and diversity of phytoplanktons (r = 0.5925; r = 0.6364). These results can be used for preliminary study of nutrient cycle model in aquaponic system.

Abstract

Perairan Asia Tenggara dan sekitarnya memiliki variabilitas laut-atmosfer yang besar akibat dari fluktuasi parameter oseanografi yang berasal dari perairan Samudera Pasifik dan Samudera Hindia pada arah zonal dan pada arah meridional berasal dari Laut Cina Selatan, perairan utara dan selatan Jawa dan perairan barat Australia. Fenomena yang dominan mempengaruhi variabilitas laut-atmosfer di wilayah Asia Tenggara dan sekitarnya adalah Muson, Dipole Mode (DM) dan El Nino Southern Oscillation (ENSO) dengan siklus waktu dari musiman sampai antar tahunan. Penelitian sebelumnya yang dilakukan lebih banyak mengkaji Muson, DM dan ENSO secara individu dari fenomenanya itu sendiri, tidak secara komprehensif mengarah kepada kemungkinan adanya interaksi satu sama lain. Tujuan dari penelitian ini adalah mengkaji variabilitas lautatmosfer dan proses dinamika interaksi antara Muson, DM dan ENSO secara simultan terhadap curah hujan di Propinsi Lampung. Analisis data yang digunakan pada penelitian ini dengan pendekatan metode yang dapat mendekomposisi sinyal tersebut baik pada skala ruang maupun waktu dari hasil interaksi antara Muson, DM dan ENSO. Analisis yang digunakan meliputi transformasi wavelet kontinyu dan korelasi silang transformasi wavelet. Dari analisis transformasi wavelet kontinu, koherensi maupun transformasi silang diperoleh kesimpulan bahwa pola curah hujan di wilayah lampung sangat dipengaruhi oleh pengaruh musiman atau adanya pengaruh WNPMI dibandingkan dengan pengaruh DMI dan SOI, akan tetapi arah fase yang berlawanan menunjukkan adanya pola pergantian pengaruh yang terjadi. DMI berpengaruh pada periode 6 bulanan, sedangakan SOI berpengaruh pada fase 12 bulanan

Abstract

Amonia merupakan parameter kualitas air yang berperan penting pada budidaya ikan. Ikan mengeluarkan limbah dari sisa pakan dan metabolisme yang banyak mengandung amonia. Permasalahan yang biasa dihadapi adalah cepatnya akumulasi limbah dari residu pakan dan hasil metabolisme ikan. Amonia akan terakumulasi dalam sistem resirkulasi dan dapat mencapai konsentrasi yang merugikan ikan jika terlalu berlebihan. Untuk mengurangi amonia pada sistem resirkulasi dapat di lakukan dengan penambahan filter. Penelitian ini bertujuan untuk mengetahui laju pengurangan amonia dan menguji jenis filter yang efektif dalam penurunan amonia pada sistem resirkulasi. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan tiga ulangan (kontrol, zeolit, arang, dan pecahan karang). Penelitian dilakukan menggunakan benih lele (Clarias sp.) 4-5 cm dalam kolam terpal berukuran 1 x 1 x 2 mdengan kepadatan 200 ekor/m2. Parameter utama dalam penelitian ini adalah amonia, dengan parameter pendukung yakni suhu, pH, dan oksigen terlarut. Hasil penelitian ini menunjukan bahwa penambahan filter berupa pecahan karang  memberikan pengaruh nyata terhadap penurunan amonia pada sistem resirkulasi.
