Sumoharjo, Ma’ruf M, Budiarto I. 2018.Biomass production of Azolla microphylla as biofilter in a recirculating aquaculture system. Asian J Agric 2: 14-19. This study utilized macrophyte (Azolla microphylla Kaulf.) as biofilter and perhaps that biomass produced in aquaculture system can be potential for alternative feed. This experiment such a first step of that vision and was aimed to determine the Azolla microphylla growth rate and its efficiency in removing ammonia from a simple recirculating aquaculture system. The experimental units were set up in three different water flow, i.e. 3 lpm, 5 lpm, and 7 lpm onto the three different geometrically baseboard of Tilapia (Oreochromis niloticus) growing tanks (prism, rectangular and limas).The result showed that water flow did not give significant effect(P < 0.10) on the growth rate of Azolla.The lower water flow (3 lpm) resulted in the highest amonia biofiltration efficiency which can remove ammonia up to 32.2±3.0% of the total NH3-N and NH4+-N (TAN).

The purpose of this research were to measure the increasing of unionized ammonia during start-up period of biofloc system for growing Nile Tilapia and to figure out its effect on histopathological changes. There was only one treatment that designed with three replication, which was 40 liters of water that contained eight fishes of each weighed 22.. The biofloc system was treated with C/N ration 12:1. Total Ammonia Nitrogen, pH and temperature were measured daily as long as 14 days. the tissue of gill, liver and kidney were cut off at the end of the experiment for histopathological examination. The result of the experiment showed that the peak of unionized ammonia concentration achieved 0.34Â±0.05 mg/l at 10th day. Then, decreased rapidly to 0.003Â±0.0009 mg/l at 14th day. The gill, liver, and kidney had regressive changes as physiologic sub lethal response of unionized ammonia expose.Â Keywords : Biofloc, unionized ammonia, Nile Tilapia, histopatholocal

Integrated multi-trophic aquaculture pays more attention as a bio-integrated food production system that serves as a model of sustainable aquaculture, minimizes waste discharge, increases diversity and yields multiple products. The objectives of this research were to analyze the efficiency of total ammonia nitrogen biofiltration and its effect on carrying capacity of fish rearing units. Pilot-scale bioreactor was designed with eight run-raceways (two meters of each) that assembled in series. Race 1-3 were used to stock silky worm (Tubifex sp) as detrivorous converter, then race 4-8 were used to plant three species of leaf-vegetable as photoautotrophic converters, i.e; spinach (Ipomoea reptana), green mustard (Brassica juncea) and basil (Ocimum basilicum). The three plants were placed in randomized block design based on water flow direction. Mass balance of nutrient analysis, was applied to figure out the efficiency of bio-filtration and its effect on carrying capacity of rearing units. The result of the experiment showed that 86.5 % of total ammonia nitrogen removal was achieved in 32 days of culturing period. This efficiency able to support the carrying capacity of the fish tank up to 25.95 kg/lpm with maximum density was 62.69 kg/m3 of fish biomass productionDoi: http://dx.doi.org/10.12777/ijse.4.2.2013.80-85 [How to cite this article: Sumoharjo, S. and Maidie, A.

Tiga spesies tanaman sayur, kangkung darat (Ipomoea reptana), sawi (Brassica juncea), dan kemangi (Ocimum basilicum) dibandingkan guna mengonversi ammonium dan nitrat nitrogen dari sistem akuakultur. Tanaman tersebut ditanam secara hidroponik menggunakan teknik rakit (rafting technique) dengan tata letak rancangan acak kelompok lengkap (RAKL). Hasil percobaan menunjukkan bahwa tingkat konversi nitrogen oleh ketiga jenis tanaman berbeda secara nyata dengan tingkat retensi nitrogen tertinggi pada tanaman kangkung sebesar 0,73±0,28 g; diikuti oleh kemangi (0,30±0,17 g); dan terakhir oleh sawi (0,03±0,07 g). Secara keseluruhan ketiga tanaman mampu menyisihkan limbah nitrogen sebesar 6,70% dari total produksi TAN dari sisa metabolisme ikan yang dibudidayakan.

Penelitian pengembangan pembenihan ikan betok (Anabas testudineus) untuk skala rumah tangga telah dilakukan untuk mengatasi sulitnya ketersediaan benih ikan betok untuk keperluan budidaya di Kalimantan Timur. Sebanyak tiga orang warga Kota Samarinda telah dipilih untuk mengembangkan pembenihan ikan betok selama delapan bulan. Sebanyak 20 ekor indukan jantan dan 30 ekor indukan betina ukuran 30-110 g/ekor, dipelihara dalam kotak kayu ulin kedap air ukuran 2 m x 1 m x 0,75 m dengan menggunakan media air hujan dan diberi makan ad libitum pagi dan sore dengan menggunakan pelet mengandung protein minimal 30%. Indukan yang telah matang gonad disuntik dengan hormon Ovaprim sesuai dosis anjuran, dan selanjutnya 2 ekor jantan dan 1 ekor betina dipijahkan dalam akuarium kaca ukuran 60 cm x 40 cm x 40 cm dengan ketinggian media air hujan 30 cm. Larva ikan betok diberi pakan 2x sehari pagi dan sore berupa larutan infusoria, dan kutu air (Moina sp.) hidup sebagai persiapan pakan lanjutan. Selain pengamatan terhadap pemahaman pembenihan ikan betok oleh pelaksana, dilakukan juga pengamatan terhadap tingkat keberhasilan pemijahan, bobot telur (butir), derajat penetasan (%), sintasan (ekor, %), jenis plankton di media, panjang dan bobot anakan pada umur empat bulan, serta kualitas air. Data yang dikumpulkan dianalisis secara deskriptif. Hasil penelitian menunjukkan pengembangan pembenihan ikan betok dapat dilakukan di tingkat rumah tangga pada lahan sempit dengan metode induced breeding, dengan 100% terjadi pemijahan, jumlah telur: 8.978-39.868 butir, derajat penetasan: 69,40%-98,14%, derajat sintasan anakan hingga usia empat bulan: 0,17% dan 0,54%, panjang total anakan usia empat bulan adalah (nilai rata-rata ± simpangan baku): 49,51 ± 15,71 mm, dan bobot: 2,46 ± 2,50 g (n= 24), hubungan antara panjang total (X) terhadap bobot (Ŷ) pada umur yang sama adalah: Ŷ=4,59 + 0,15X dan keeratan korelasi (r) sebesar: 0,96. Ikan betok dapat dibudidayakan pada media air hujan dengan kejenuhan oksigen: 1,50%-47,4%, kelarutan oksigen: 0,12-3,80 mg/L, dan pH: 3,45-5,85. Rendahnya sintasan benih ikan betok utamanya disebabkan oleh tingginya pemangsaan antar sesama (kanibalisme) sejak benih berusia lebih dari satu minggu, dan sulit untuk dikendalikan.

Seaweed K. alvarezii has been cultured massivelly along eastern kalimantan coastal zone. Meanwhile, every region potentially has diverse trophical status that affects its carraginan content. This study aimed to compare the thropical status of cultured seaweed location that situated in two region (Bontang and Panajam Paser Utara, PPU) and of its carragenan content. Seaweed in two different age (30 and 40 days) are sampled as well as water quality. Total Nitrogen (TN) and Total Phosphrous (TP) in particular are measured. The result showed that Bontang coastal area has Trophical Index (TRIX) 5,9 (meant high trophic level). the value was contrast with PPU that had 3,8 of TRIX meant low trophic level. However, carragenan content of seaweed from Bontang has lower than PPU, were 45 % and 64 %, respectivelly. Rumput laut (Kappaphycus alvarezii) sudah dibudidayakan secara luas di pantai Kalimantan Timur. Sementara itu, setiap wilayah berpotensi memiliki status kesuburan perairan yang berbeda yang akan mempengaruhi kandungan karaginan rumput laut yang dibudidayakan. Penelitian ini bertujuan untuk membandingkan status trofik lokasi pembudidayaan rumput laut dan kandungan karaginannya pada dua wilayah, yakni di perairan Bontang dan di perairan Panajam Paser Utara (PPU). Sampel rumput laut diambil pada dua umur tanam berbeda (30 dan 40 hari), serta dilakukan pengukuran dan sampling kualitas airnya. Terutama, parameter Total Nitrogen (TN) dan Total Fosfor (TP). Hasil penelitian ini menunjukkan bahwa Perairan Bontang memiliki Indeks Trofik (TRIX) 5,9 (berarti kesuburan tinggi), namun sebaliknya, pada perairan PPU memiliki Indeks Trofik 3,9 (berarti kesuburan rendah). Akan tetapi, kandungan karaginan rumput laut dari Bontang justru lebih rendah dibandingkan dengan PPU, yakni; 45 % dan 64 %
