Phytoplankton is a source of natural feed for shrimp cultivation in the pond. Phytoplankton productivity increases by the increasing 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 whiteleg shrimp, <em>Litopenaeus vannamei </em>cultivation system. This study was conducted at three intensive whiteleg 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 of ammonia nitrogen (TAN), nitrate, orthophosphate, total of suspended solid (TSS), and chlorophyll-a were measured. Identification and density of phytoplankton were also performed of each pond. The result showed that productivity of three ponds was 22,893.83 kg/ha to 23,600.61 kg/ha with an average size 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 <em>Oocystis, </em><em>Chlorella, Nannochloropsis, Chaetoceros</em>, <em>Stephanodiscus, </em><em>Nitzschia, Coscinodiscus, Cyclotella </em>and <em>Ulothrix. </em>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 present of phytoplankton in the pond provide natural feed and good environmental condition for shrimp cultivation.

                                                    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.

Provinsi Lampung merupakan salah satu wilayah penghasil udang vaname terbesar di Indonesia. Produktivitas udang vaname di Lampung mengalami pasang surut, salah satunya dikarenakan serangan penyakit golongan virus seperti WSSV, IHHNV dan IMNV. Penelitian ini bertujuan untuk mengevaluasi status penyebaran penyakit WSSV, IHHNV dan IMNV pada udang vaname dan mengevaluasi keefektifan penerapan Cara Karantina Ikan yang Baik (CKIB) dalam menekan penyebaran virus tersebut di Provinsi Lampung. Pada penelitian ini, dilakukan pengumpulan data pengujian pada tahun 2019 yang berasal dari sampel umum, kegiatan pemantauan Penyakit Ikan Karantina (PIK) dan kegiatan CKIB, kemudian dilakukan analisa secara deskriptif. Hasil penelitian menunjukkan bahwa di Provinsi Lampung masih terdapat penyakit virus udang yaitu WSSV, IHHNV dan WSSV yang tersebar di sentra budidaya udang vaname. Dari sejumlah 624 total sampel pengujian, sebanyak 8.97% positif terinfeksi penyakit virus. WSSV memiliki tingkat infeksi terbesar yaitu 58.9%. Sedangkan untuk IMNV dan IHHNV masing-masing sebesar 33.9% dan 7.1%. Berdasarkan asal sampel pengujian dapat diketahui bahwa sampel yang diperoleh dari pembudidaya yang telah menerapkan CKIB menunjukkan hasil negatif untuk ketiga jenis virus target tersebut. Hal tersebut memberikan gambaran bahwa dengan penerapan CKIB secara konsisten dapat mengurangi tingkat penyebaran penyakit virus pada budidaya udang vaname.ROLES OF GOOD QUARANTINE PRACTICES IN THE SPREAD OF VIRUS DISEASES OF VANNAMEI SHRIMP (Litopenaeus vannamei) IN PROVINCE OF LAMPUNG. Lampung is one of the largest whiteleg shrimp (L. vannamei) producers in Indonesia. Whiteleg shrimp productivity in Lampung has fluctuated, one of which is due to infectious by virus disease. This study evaluated the current status of WSSV, IHHNV and WSSV diseases in whiteleg shrimp cultivation and assesses the effectivity of CKIB implementation in preventing the outspread of the shrimp viral diseases in Lampung. In this study, data from general samples, diseases monitoring/surveillance and Good Quarantine Practices (GQP) activities in 2019 were collected and then analyzed descriptively. Here, were report the emergence of shrimp viral diseases, e.g. WSSV, IHHNV and WSSV, in whiteleg shrimp aquaculture in Lampung. Infected shrimp were found in 8.97% of 624 tested samples. WSSV has the highest infection rate (58.9%) and followed by IMNV and IHHNV (33.9% and 7.1%, respectively). The samples collected from whiteleg shrimp aquaculture centre that applied GQP showed negative viral disease infection. These results demonstrate that consistent application of GQP in whiteleg shrimp cultivation can prevent the spread of shrimp viral disease.

The main pigments found in oil palm tree leaf are chlorophylls a, b, and c. Chlorophyll a converts light energy into chemical energy through photosynthesis process. The content of chlorophyll pigments varies by their ages. The aim of this research was to determine the concentration in chlorophyll a in different ages. This study is significant in oil palm fertilization for monitoring oil palm nutrient content (NPK). Chlorophyll measurement was done by extracting using methanol solvent and concentration measurement using spectrophotometric method in order to quantify chlorophyll a concentration based on their ages. 6 samples of oil palm tree leaves, collected from 2 different ages, were analyzed. The observed values were determined based on the absorbance at wavelength (670nm) and were calculated for concentrations value based on to the Lambert-Beer law Equation. It showed that the chlorophyll a concentrations at the age of mature stage had been higher than those at the old stage. The results depicted that the chlorophyll a concentration values at the mature stage were 0.33mg/ml, 0.32mg/ml, and 0.18mg/ml, while at the old stage were 0.22 mg/ml, 0.18mg/ml, and 0.06mg/ml.
