<![CDATA[Intensive catfish farming can cause a decrease in the water quality of the culture media, including decreasing dissolved oxygen content and increasing waste content, especially organic nitrogen. The application of Biofloc technology was carried out by the Young Independent Fish Cultivator Group (Pokdakan) with the aim of managing catfish farming activities in Lam Ara Village, Banda Raya District, Banda Aceh City using Biofloc on cultivation media. The purpose of this study was to compare the growth of catfish reared using Biofloc and non-Biofloc culture media. The test animals used in this study were catfish with Sangkuriang variety (Clarias gariepinus) measuring 7-8 cm as many as 2,000 fish in 8 different containers. Observations were made on the day of stocking until harvesting. The growth parameters observed were the length and weight of the fish. The environmental parameters observed were water temperature, dissolved oxygen, and pH. The results showed that there were differences in the increase in length and body weight of catfish in the cultivation media of Biofloc and non-Biofloc applications. The results of this study indicate that the application of the biofloc method can increase the productivity of tarpaulin ponds. The rearing media that applied the Biofloc technique showed better and relatively ideal conditions for catfish cultivation.]]>

<![CDATA[Mikroalga dikenal sebagai salah satu sumber utama penghasil bahan baku biodiesel untuk energy yang terbaharui karena kaya akan kandungan minyak. Penelitian ini mengkaji pengaruh Nitrogen dan metode ekstraksi terhadap kandungan lipida/minyak mikroalga hijau yang telah diaklimatisasi dalam limbah peternakan. Penelitian dilakukan dalam wadah kultivasi (fotobioreaktor) volume 2 L pada konsentrasi sumber Nitrogen berbeda (0 – 0,4 g/L KNO3). Selain itu juga diteliti keefektifan dua metode ekstraksi (Bligh – Dyer, dan Bligh – Dyer Modifikasi) untuk memperoleh minyak alga semaksimal mungkin. Hasil penelitian menunjukkan penambahan sumber Nitrogen yang berbeda pada kultivasi mikroalga yang telah di aklimatisasi memberikan kenaikan jumlah kandungan biomassa yang signifikan daripada yang tidak ditambahkan sumber nitrogen (kontrol). Sebaliknya kandungan lipid/minyak alga semakin menurun dengan tingginya kandungan sumber nitrogen dalam biomassa alga. Penggunaan dua metode ekstraksi berbeda tidak berpengaruh signifikan terhadap kandungan total lipida/minyak dari mikroalga. Hasil analisa GC-MS pada total lipida mikroalga menunjukkan komposisi terbesar berupa n-heksadecanoic acid (asam palmitat), octadecanoic acid (asam stearat) dan 9-(Z) octadecenoic acid (asam oleat), yang dapat berpotensi sebagai bahan baku biodiesel.]]>

<![CDATA[This study examines CO2 for the growth of green microalgae by cultivating algal strains in a tank type reactor or fermentor. The study included optimization of the productivity of green algae in the capture of CO2 which can be used as a greenhouse gas catcher. Green algae were isolated from several waters in Banda Aceh and Aceh Besar. The microalgae species of this isolation and its identified species were subsequently cultivated in a tank-shaped cultivation (cultivation) container with 4 flourescent lamps (2x8 watts; 4x8 watts) installed on the outside side of the tank. This study evaluated the comparison of the growth of aerated microalgae O2 (1.25 liters / minute) with fixation of CO2 (1 and 2 liters / minute). The capture of CO2 into carbon dioxide is done by looking at the growing biomass, and the yield content of oil in biomass. The results showed that there were significant differences in the growth patterns of microalgae given O2 aeration and CO2 fixation. Modified CHU 13 Detmer Modified media does not provide a significant difference to algal growth. With a large intensity of light with a medium that is sufficient to increase the growth of microalgae until it reaches the death phase. Component analysis by Chromatography Gas Mass Spectrometry (GC-MS) shows that the largest component in vegetable oils from green microalgae is Palmatic acid (9.36%), Thiogeraniol (24.63%), Cyclopropane Methanol (2.45%), Farnesol ( 2.39%), Trimethyl (2.78%) and Dodencadien (5.06%). ]]>
