Abstract

Fish is the potential protein source for human. People consumption of fish requires attention related to whether the fish is safe to consume. This research is aimed at finding kind of parasite attack Groupers (E. fuscoguttatus) and the prevalence and the infection level in the different farming location. The research method used that is by taking Groupers size between 10 cm - 35 cm as many  fish from all population in each location with the assumption of percentage the prevalence used was 10%. Sample then analyzed for amount and type of parasite attacked and determined level of prevalence and degree of parasite infection. Result showed the type of parasite attack Groupers are Anasakis sp., Diphyllobothrium sp., Caligus sp., Diplectanum sp., Ergasillus sp., and Argulus sp. The different location of farming didn’t influence the parasite prevalence degree in Groupers. It is known that in location 1 in Lamongan, the prevalence level is 60% and the amount of fish attacked is 12, while in location 2 which is in Situbondo regency the prevalence degree is 50% with 10 fish attacked. t-test result showed that the level of infection degree did not differ perhaps because of the water condition quality between two location was relatively similar and still in the normal category, and also farmers have known the farming techniques well. Key Words : Prevalence, Degree of parasite infection, Groupers

Abstract

Penelitian ini bertujuan untuk mengetahui struktur komunitas dan kelimpahan fitoplankton dan faktor yang mempengaruhi di perairan muara sungai Porong Sidoarjo. Metode penelitian dilakukan dengan metode deskriptif yang bersifat ex post facto. Analisis sampel air dilakukan di Laboratorium Tanah dan Laboratorium Ilmu Kelautan Universitas Trunojoyo. Dari hasil penelitian menunjukkan bahwa Struktur komunitas fitoplankton yang ada di perairan muara Sungai Porong terdapat 2 kelas yaitu Bacillariophyceae (14 genera) dan Dinophyceae (2 genera) dengan kelimpahan berkisar antara 18.077 sel/L - 29.305 sel/L. Indeks Keanekaragaman menunjukkan kestabilan populasi rendah dengan indeks keseragaman yang rendah sehingga tidak ada dominansi species. Faktor yang mempengaruhi kelimpahan fitoplankton adalah tingkat kecerahan perairan yang rendah akibat tingginya bahan tersuspensi. Kata Kunci : Struktur Komunitas, Fitoplankton, Muara Sungai Porong

Abstract

This research was conducted on July to September 2009. Mangrove litterfall were trapped with 30 litter traps which were plotted under mangrove canopy 1.5 m above the ground, hence the traps were avoided from tide. In this research, we use Rhizopora mucronata, Rhizopora apiculata and Bruguera sp. 10 litter traps were used on each species. Litter traps were made from polyetilen with size of 1x1x0,5 m3. Mangrove litterfall were collected every two weeks for 3 months. The production rate of mangrove litterfall in Bangkalan were 4.08-18.38 g/tree/day. The fastest production rate of mangrove litterfall was found on Rhizopora mucronata with 64.56%, followed by Rhizopora apiculata and  Brugueira sp with 24.32% and 11.12%, respectively. Key Words : mangrove litterfall, Bangkalan, Rhizopora

Abstract

Teripang atau Timun laut (Echinodermata) adalah salah satu jenis komoditi laut yang bernilai domestik maupun internasional sub sektor perikanan yang cukup potensial. Salah satu zat bioaktif yang terkandung dalam teripang adalah senyawa steroid. Penelitian ini bertujuan menentukan tingkat efektivitas ekstrak kasar daging teripang yang telah diformulasikan dalam air media pemeliharaan juvenile udang galah terhadap keberhasilan mendapatkan jantan fenotif. Hipotesa yang dipakai pada penelitian ini adalah bahwa masa aktif pemberian ekstrak kasar daging teripang hasil formulasi yang diberikan dalam air media, efektif dapat berpengaruh dalam perkembangan juvenil menjadi jantan fenotif. Metode perendaman dengan dosis ekstrak teripang 10 mg/L, 15 mg/L dan 25 mg/L, dapat menghasilkan populasi jantan lebih tinggi dari kontrol (kontrol negatif/tanpa perlakuan hormon). Kata Kunci : teripang, steroid, jantan fenotif

Abstract

Satelit NOAA-17 adalah salah satu seri satelit yang dimiliki oleh NOAA (National Oceanic and Atmospheric Administration) Amerika dan juga merupakan satelit lingkungan dan cuaca yang memiliki resolusi temporal yang tinggi. Seri dari satelit NOAA telah mencapai seri ke 19 yang dapat diartikan bahwa satelit ini telah beroperasi cukup lama. Satelit ini telah banyak digunakan oleh para peneliti untuk mengetahui Tingkat Kehijauan Vegetasi (NDVI), Suhu Permukaan Laut (SPL),  Hotspot. Pada penggunaannya untuk mengetahui SPL, satelit NOAA memiliki band 4, band 5 yang merupakan band Thermal Infrared dan merupakan band yang sensitif terhadap perubahan suhu di laut. Pengolahan untuk mengukur variasi SPL yang menggunakan band 4 dan band 5 yang telah dikalibrasi, hasil dari kalibrasi tersebut yang kemudian dimasukkan kedalam algoritma Mc Millin dan Crosby, sehingga didapatkan nilai suhu permukaan laut dari setiap data citra satelit NOAA-17 Tanggal 15 Juni 2009; 6 Juli 2009; 1 Agustus 2009 yang diolah. Kata Kunci : Data Citra NOAA-17, Suhu Permukaan Laut, Algoritma Mc Millin dan Crosby

Abstract

In order to assess the extent of the decline of mangrove ecosystems, extensive mapping and monitoring programs are needed. To monitor the change in large-scale coverage of mangrove areas over certain periods of time, remote sensing technology offers many advantages compared to conventional field monitoring. The main benefit of using remote sensing is related to its speed and continuity in collecting space images of a broad area of the Earth’s surface. With the specific application on mangrove studies, remote sensing enables spatial and spectral information to be collected from the mangrove forests environment mostly located in inaccessible areas, where ground measurements become difficult and expensive. This review of the literature emphasizes the application of remote sensing in change detection and mapping of mangrove ecosystems. Key words : mangroves, remote sensing, mapping, field monitoring, continuity

Abstract

Geographic Infiormation System modeling can be used to  predict inundated area expansion that caused by mud flow. The alternative location of Lapindo mud flow can be identified from inundated area prediction. The aims of this research are 1) to appraise the accuracy of elevation data interpolation methods and IKONOS imagery accuracy in determinant variable retrieval, 2) to determine the alternative pond of Lapindo mud flow, 3) to evaluate volume capacity and to analyze the construction cost.The method of this research consist of determinant variable retrieval, these are: inundated zone,  land use, public facilities and impacted area. Inundated zone map was retrieved from DEM interpolation result, the watershed modeling was done to get flow accumulation, flow direction and watershed, in order to get inundated zone. Land use map and public facilities were obtained from IKONOS imagery visual interpretation. Impacted area was determined according to President Regulation No. 14, 2007. Scoring, weighting and overlay of these four maps have been made to get mud flow alternative location. Weighting factors have been retrieved according to questioner result.The result of this research has shown that Kriging interpolation method was the best method for elevation data interpolation (RMSE = 1.3565). Land use interpretation accuracy achieves 93.5%. Public facilities interpretation accuracy achieves 100%. Nine candidates of mud exile alternative pond have been got as a research result. Alternative pond No.1 is the best pond, with 4.027 Ha area. Volume pond capacity achieves to 564.599.751 m3, with 3.704 days or 10 years endurance. Total co[1]st of pond construction achieves Rp. 7.276.313.970.000.  Keywords: site selection, watershed, mud, Lapindo.
