Abstract

Nitrat dan fosfat adalah unsur nutrien yang menjadi pembatas kelimpahan fitoplankton. Kandungan nitrat dan fosfat di perairan muara akan dipengaruhi oleh faktor biologi, fisika dan kimia perairan, yang menyebabkan timbulnya suatu persebaran. Hal tersebut menjadi permasalahan di Muara Sungai Bodri, Kendal. Tujuan dari penelitian ini adalah untuk mengkaji kandungan nitrat dan fosfat beserta pola persebarannya, serta keterkaitannya dengan struktur populasi fitoplankton sebagai bioindikator kesuburan perairan di Perairan Muara Sungai Bodri, Kabupaten Kendal. Penelitian dilaksanakan berdasarkan metoda observasi dengan pendekatan spatio-temporal. Sejumlah 9 stasiun penelitian dan 3 kali waktu sampling yaitu 30 Juni, 1 September dan 27 Oktober 2018. Kandungan nitrat dan fosfat serta kelimpahan fitoplankton ditetapkan sebagai variabel terikat. Sedangkan parameter fisika dan kimia perairan seperti suhu, salinitas, derajat keasaman (pH), oksigen terlarut, kecerahan dan arus ditetapkan sebagai variabel kontrol. Hasil penelitian menunjukan bahwa kandungan nitrat berkisar 0,49-0,9 mg/l serta kandungan fosfat berkisar 0,01-0,29 mg/l yang menunjukkan bahwa perairan Muara Sungai Bodri, Kabupaten Kendal dalam kondisi subur/eutrofik. Kelimpahan fitoplankton menunjukkan nilai kisaran diantara 2.356 sampai dengan 162.626 sel/l, yang tersusun oleh 5 kelas dan 45 jenis/species dengan pola persebaran berbentuk konvergen yang bertumpu pada stasiun 3 dan 5.

Abstract

Indonesia produces 64 million tons of plastic waste every year and 3.2 million tons of it is thrown into the sea, so research needs to be done to create plastic that is environmentally friendly and easily decomposed (bioplastic). Alginate and carrageenan are polysaccharides produced from seaweed which have potential as materials for making bioplastics. This research aims to determine the effect of alginate and carrageenan on the quality, physical properties, mechanical properties and biodegradability of carrageenan-chitosan bioplastics with glycerol plasticizer. Carrageenan is obtained from extraction of Kappaphycus sp. who comes from the Yapen Islands, Papua Province. Making a carrageenan bioplastic solution by dissolving carrageenan flour (1; 1.5; 2; 2.5 grams) and 5 ml of glycerol in 100 ml volume of vingga distilled water then heating using a magnetic stirrer for 15 minutes at 90oC. The process of making a chitosan solution is by dissolving 2 grams of chitosan, 3 ml of glycerol, and 1 ml of glacial acetic acid in 94 ml of distilled water then heating with a magnetic stirrer for 10 minutes. The research results show that. The best concentration of carrageenan in the alginate-carrageenan composite bioplastic is 1.5 grams because it has physical and mechanical properties that meet the Japanese Industrial Standard and SNI 7188.7:2016 except for water resistance.

Abstract

Background: Phytoplankton is one of the microalgae that has great potential as an energy source, one of which is Chlorella sp.. Chlorella sp. is the largest producer of protein compared to other types of phytoplankton. The lipid and fatty acid content in microalgae is a source of energy that plays a role in the process of making biodiesel. Phytoplankton type Chlorella sp. easy to cultivate and breed. Supporting breeding in the process is supported by the use of fertilizers that are rich in nutrients so that it will optimize the growth of these phytoplankton. Generally fertilizer is divided into two, namely inorganic fertilizer and organic fertilizer. The aim of this research was to determine the fat content of Chlorella sp. which was obtained from the results of culture with the treatment of giving skipjack tuna fertilizer through a proximate test. Methods: This research was conducted by taking samples of Chlorella sp. At Base-G Beach. Samples were cultured and added liquid fertilizer from skipjack fish waste at a concentration of 4;8;12 ml/L. Chlorella sp. The culture results were calculated for cell density and tested for fat content through proximate fat analysis. Results: The study showed that the density of microalgae cells produced ranges from 0.21 x106 cells/ml to 0.51x106 cells/ml. The average proximate analysis of fat in microalgae was 0.022%-0.039% (w/w). The application of skipjack tuna waste fertilizer affected the proximate fat value of Chlorella sp. (p<0.05). Conclusion: The proximate fat content in Chlorella sp samples from Base-G beach which were cultured with the addition of liquid skipjack tuna waste fertilizer was 0.022-0.039% (w/w).
