Abstract

The influence of freshwater tidals zone at Bandengan and Panjang Island could be seen by extensive finding of freshwater plankton such as Anabaena, Nitzschia, Oscillatoria, Tolypothrix, Surirella, Euglena, Volvox, and Spirogyra. Partially, salinity in Bandengan water was 30 – 33 o/oo, pH ranged between 8 – 9, and nitrite was zero, wich was in compliance with the criterian for seawater (Kep-02/MENKLH/I/88). The high level of SiO2 in Bandengan waters (1.20 – 3.29 mg/l) and Panjang Island (1.58 – 3.30 mg/l) supported the dominance of Chrysophyceae, especially Diatomae, in the study areas.  Keywords : Nutrient, Plankton, Bandengan, Panjang Island

ABSTRAK Limbah pencucian ikan bersumber dari kegiatan pencucian bagian luar dan dalam tubuh ikan. Limbah pencucian ikan memiliki kandungan senyawa amoniak, nitrit, dan nitrat yang tinggi sehingga kemungkinan mempunyai efek negatif bagi lingkungan. Sebagian besar industri pengolahan ikan belum melakukan pengolahan limbah cairnya dengan baik. Bioremediasi merupakan metode biologi dengan memanfaatkan mikroorganisme dan tumbuhan air Lemna minor dalam pengolahan air limbah. Penelitian ini bertujuan untuk mengetahui efektivitas dan pengaruhdari kombinasi mikroorganisme dan Lemna minor dalam mereduksi senyawa amoniak, nitrit, dan nitrat pada limbah pencucian ikan. Metode penelitian yang digunakan adalah eksperimen skala laboratorium dimana wadah percobaan berisi limbah pencucian ikan dengan volume 1 Liter. Desain penelitian yang digunakan yaitu percobaan faktorial 3 x 3 dengan 2 faktor, sehingga terdapat 9 kombinasi perlakuan M1L10, M1L50, M1L100, M5L10, M5L50, M5L100, M10L10, M10L50, dan M10L100, dimana “M” faktor konsentrasi mikroorganisme (1 mL/L, 5 mL/L, 10 mL/L), sedangkan “L” faktor bobot biomassaLemna minor (0,0255 gr/cm2, 0,1273 gr/cm2 , 0,2546 gr/cm2).

Abstract

Kegiatan budidaya pada setiap prosesnya menghasilkan limbah yang dihasilkan dari sisa-sisa pakan dan kotoran yang berasal dari ikan budidaya, terutama budidaya Ikan Nila yang merupakan salah satu jenis ikan tawar yang sudah di budidaya secara komersial oleh masyarakat indonesia. Penelitian dilaksanakan pada Mei-Juni 2017 di Laboratorium Pengelolaan Sumberdaya Ikan dan Lingkungan, Departemen Sumberdaya Akuatik, Fakultas Perikanan dan Ilmu Kelautan, Universitas Diponegoro. Pada penelitian ini ditambahkan enzim pada pakan ikan, suatu enzim yang mengandung protease, lipase, amilase, pepsin, tripsin, dan kemotripsin dalam dosis yang sudah ditentukan untuk memaksimalkan proses pencernaan. Ikan Nila yang digunakan  berukuran 7-9 cm dipelihara di dalam akuarium dengan kapasitas 2 ekor Ikan Nila dalam 1 akuarium dengan volume air 9 l. Tujuan penelitian untuk mengetahui konsentrasi amoniak, nitrit, dan sulfida (H2S) dan membandingkan pengaruh pemberian enzim dengan konsentrasi yang berbeda didalam pakan terhadap konsentrasi amoniak, nitrit, dan sulfida (H2S). Metode yang digunakan adalah metode eksperimental skala laboratorium. Desain penelitian berdasarkan rancangan acak lengkap (RAL), dengan menggunakan lima perlakuan yaitu dengan perbedaan konsentrasi enzim. Setiap perlakuan dilakukan 3x pengulangan. Analisis data menggunakan uji two way anova. Hasil penelitian menunjukkan bahwa pemberian enzim dengan konsentrasi berbeda tidak berpengaruh nyata, lama waktu pemeliharaan berpengaruh nyata terhadap konsentrasi amoniak, dan sulfida, kombinasi dari keduanya tidak berpengaruh nyata terhadap konsentrasi amoniak, nitrit, dan sulfida. Cultivation activities in each process produce waste generated from the remnants of feed and feces from the fish cultivated, especially the cultivation of tilapia which is one type of fresh bonds that have been cultivated commercially by the people of Indonesian. The research was conducted in May-June 2017 at the Fish and Environmental Resource Management Laboratory, Aquatic Resources Department, Fisheries and Marine Science Faculty, Diponegoro University. The materials on this research are combining the fish feed with an enzime which contains protease, lipase, amylase, pepsin, trypsin, and chemotrypsin in prescribed doses to maximised the digestion process. Tilapia as research object has length of 7 to 9 cm and its kept in an aquarium with capacity (water volumes) of 9 ls which contains of 2 tilapias. The purposes of this research are to know the concentration of ammonia, nitrite and sulfide (H 2 S) in and to compare the effect of the enzyme provision with different concentration in fish feed with the concentration of ammonia, nitrite and sulfide (H 2 S). This research used laboratory-scale experimental method. The study design was based on Complete Randomized Design (RAL), using five treatments with different enzyme concentrations. Each treatments was done by three repetitions. The data was analysed using two-way ANOVA test. The results showed that enzyme with different concentration had no significant effect, maintenance time had significant effect on ammonia concentration, and sulfide, the combination of both did not significantly affect the ammonia, nitrite and sulphide concentration.
