Abstract

                                                    AbstrakFitoplankton merupakan sumber pakan alami pada budidaya udang di tambak. Produktivitas fitoplankton dapat meningkat seiring dengan bertambahnya kandungan nutrien di tambak. Sisa metabolisme dan pakan merupakan sumber nutrien bagi pertumbuhan fitoplankton di tambak. Penelitian ini bertujuan untuk mengevaluasi produktivitas dan mengidentifikasi jenis fitoplankton pada sistem budidaya intensif udang vaname, Litopenaeus vannamei. Penelitian ini dilakukan pada tiga petak tambak budidaya intensif udang vaname di Probolinggo, Jawa Timur. Pengambilan sampel air tambak dilakukan pada hari ke-17 dan hari ke-87 masa budidaya masing-masing dua kali setiap petak. Empat parameter lingkungan yaitu total ammonia nitrogen (TAN), nitrat, orthophosphate, total padatan tersupensi (TSS), dan klorofil diukur pada setiap sampel air tambak. Selain itu, kami juga mengidentifikasi dan menghitung fitoplankton pada setiap sampel. Hasil penelitian ini menunjukkan bahwa produktivitas pada ke tiga tambak berkisar antara 22.893,83 kg/ha sampai 23.600,61 kg/ha dengan ukuran panen 12,74 g/ekor sampai 14,35 g/ekor. Selama masa budidaya, konsentrasi TAN, TSS, dan klorofil meningkat seiring dengan semakin lamanya masa budidaya. Sementara itu, rerata kandungan nitrat dan orthophosphate cenderung menurun seiring bertambahnya masa budidaya. Jenis fitoplankton yang teridentifikasi yaitu dalam genus Oocystis, Chlorella, Nannochloropsis, Chaetoceros, Stephanodiscus, Nitzschia, Coscinodiscus, Cyclotella, dan Ulothrix. Fitoplankton dari kelompok Chlorophyta merupakan jenis yang dominan pada tambak 1 dan 2, sedangkan tambak 3 didominasi oleh kelompok Diatom. Penelitian ini mengindikasikan bahwa keberadaan fitoplankton di tambak mendukung ketersediaan pakan alami dan lingkungan yang baik bagi budidaya udang.                                                      AbstractPhytoplankton is a source of natural feed for shrimp cultivation in the pond. Phytoplankton productivity increases by the increased nutrient content in the pond. Feed and metabolic waste is the sources of nutrient for phytoplankton growth. This study aimed to evaluate productivity and identify phytoplankton at intensive white leg shrimp, Litopenaeus vannamei cultivation system. This study was conducted at three intensive white shrimp located in Probolinggo, East Java. Samples were collected on the early and the late of culture period (day 17 and 87 after stocking). Four environmental parameters including total ammonia nitrogen (TAN), nitrate, orthophosphate, total suspended solids (TSS), and chlorophyll-a were measured. Identification and density of phytoplankton were also performed of each pond. The result showed that the productivity of three ponds was 22,893.83 kg/ha to 23,600.61 kg/ha with an average size of 12.74 g to 14.35 g. During culture period, the concentration of TAN, TSS, and chlorophyll-a tended to increase. Meanwhile, the average of both nitrate and orthophosphate tended to decline. Several phytoplankton identified in this study were in the genus of Oocystis, Chlorella, Nannochloropsis, Chaetoceros, Stephanodiscus, Nitzschia, Coscinodiscus, Cyclotella, and Ulothrix. Phytoplankton of the group Chlorophyta is predominance for pond 1 and 2, while pond 3 was dominated by phytoplankton in the group of Diatom/Baccillariophyta. This study indicated that the presence of phytoplankton in the pond provides natural feed and good environmental condition for shrimp cultivation.

Abstract

HighlightCassava leaves (Manihot utillisima) identification and analysisObserving the content of anti-nutritional cyanide (HCN) in cassava leavesOrganoleptic testing in the fermentation process of Lactobacillus plantarum     bacteria against cassava leaves (Manihot utilissima)Knowing the nutritional content of cassava leaves, after fermentation process that use the different Lactobacillus plantarum bacteriaKnowing the nutritional content of fermented cassava leaves (Manihot utilissima)AbstractCassava leaves (M. utilissima) are well used as a staple ingredient for feeding livestock mainly for high nutrient content especially protein which is 27%. The main problem in the use of cassava leaves as fish feed ingredients is its high fiber content, making it difficult to be digest by fish. The main purpose of this research was that fermented cassava leaves by using L. plantarum could increase its protein content. This research was conducted by adding the different concentrations of L. plantarum which were 0 cell/ml, 1012 cells/ml, and 1013 cells/ml, 1014 cells/ml, and repeated three times. The result showed that L. plantarum with the concentration of 1014 cells/ml provides the best results overall in increasing protein content by 35.8% and physical characteristic test including scent, texture, hypha quantity, and water vapor provides the best result

Abstract

Highlight Research Each species of microalga has a preferable nitrogen source for their optimal growth. The nitrogen sources in the grown media affected the growth rate and biochemical composition of Chlorella FNUB01. (NH2)2CO (urea) was found to be the best alternative nitrogen source for Chlorella FNUB01. For producing 1 g of Chlorella FNUB01, the use of urea reduced the cost of medium by 72.6%. Abstract Chlorella sp. is a potential microalgae species to be produced commercially for feed, growth accelerator, and immuno-modulator in fish and shrimp culture. This study aimed to evaluate the various nitrogen sources on the growth, biomass production, and biochemical composition of Chlorella sp. FNUB01. The nitrogen sources used in this study were urea (NH2)2CO, potassium nitrate (KNO3), and ammonium nitrate (NH4NO3). Sodium nitrate (NaNO3) was used as a control as it is a part of the commercial medium BG-11. Generally, the sources of nitrogen in the media affected the growth and chemical composition of Chlorella sp. FNUB01. This green microalga grew better in the urea-containing medium which accounted for 1.5 times the concentration of that cultured in BG-11 (40 x106 cells. mL-1). Meanwhile, this microalgae species experienced the lowest growth when cultured in NH4NO3-containing medium. The biomass productivity of Chlorella sp. FNUB01 cultured in urea (0.93 g.L-1) was comparable to those grown with NaNO3 as the N source. A similar pattern was recorded for protein, chlorophyll, and carotenoid content as these biochemical contents were affected by N availability in the medium. Urea was an alternative low-cost N source for the culture of Chlorella sp. FNUB01. Replacement of NaNO3 with urea could reduce the cost of the medium by 72.6%.
