Abstract

Terminalia catappa is commonly present in tropical area  and its can be used for increasing pH in fish culture and it also be used as disinfectant.  A research aims to understand the dosages of T. catappa leaf extract to hamper the growth of Aeromonas hydrophila  has been conducted  from February  to July 2019.  A diffusion agar KIRBY BAUER method was applied to understand the sensitivity of T. catappa  toward the A. hydrophila. Treatments applied were P0 (Control, Oxytetracyclin (30 µg.Disk), P1 (100%), P2 (90%), P3 (80%), P4  (70%), P5 (60%), P6 (50%), P7 (40%), P8 (30%), P9 (20%), P10 (10%) P11 (9%), P12 (8%), P13  (7%), P14 (6%), P15 (5%), P16 (4%), P17 (3%), P18(2%), P19 (1%). Pure leaf extract was obtained from fresh leaf. The disk blank was wet with 50 L of leaf extract. A. hydrophila was cultured in TSA, TSB and GSP media, and it was grew up for 24 hours. Results shown that the pure leaf extract produce  13.9 mm diameter clear zone, while 2% of pure extract produce 6.5 mm diameter clear zone.

Abstract

Total Suspended Matter (TSM) dan klorofil-a merupakan parameter kualitas air yang dapat dipetakan dengan penginderaan jauh. Nilai TSM yang tinggi dapat mempengaruhi klorofil-a dalam fitoplankton untuk berfotosintesis. Penelitian ini bertujuan untuk menganalisis sebaran, akurasi, serta hubungan antara parameter TSM dan klorofil-a berdasarkan data in situ dan data citra di perairan Pesisir Prigi. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif. Data yang digunakan adalah citra Landsat 8 tanggal 20 Mei 2018 dan sampel in situ yang diambil dengan menggunakan teknik purposive sampling di 9 lokasi pada tanggal 19 Mei 2018. Dari penelitian ini didapatkan hasil nilai TSM in situ berkisar 41-64 ppm, nilai TSM citra berkisar 44–65 ppm, nilai klorofil-a in situ berkisar 1,15-2.68 mg/m3, dan nilai klorofil-a citra berkisar 1,24-2,41 mg/m3. Dari hasil data in situ dan citra didapatkan akurasi sebesar 74,37% untuk TSM dan 80,33% untuk klorofil-a. Nilai hubungan TSM dan klorofil-a adalah y= -0.045x + 3.9103 dengan nilai koefisien 85%, yang artinya variabel X yaitu TSM mempengaruhi variabel Y yaitu klorofil-a. Kesimpulan dalam penelitian ini adalah perairan Pesisir Prigi memiliki nilai yang berada pada ambang batas masing – masing parameter, sehingga perairan Pesisir Prigi tergolong baik. Akurasi yang tinggi antara data citra dan data in situ menunjukkan metode penginderaan jauh sesuai untuk digunakan di wilayah perairan Pesisir Prigi.

Abstract

Toba in the past few years has declined in fish catching populations. In order to find out the fisheries of lake Toba with quickly used the acoustic methode using the de-tected backscattering strength volume of fish. The amis of this research is to determine the distribution of spatial backscattering strength of fish in the lake toba. The research was carried out in the lake toba using scientific echosounder DT-X split beam re-cording device 38-1000 KHz during six days in September. The results of the acoustic data processing showed that the highest Sv value was at depth of 50-75 m which is -32, 29 (dB) and the average is -55,82 (dB), Sv was detected on the eastern edge of lake toba waters, while the lowest Sv was detected at depth of 25-50 m which is 60.00 (dB) with the mean is -57,93 (dB) spread over the edge of the southern part of lake toba. This is influenced by the condition of the aquatic enviroment an habits of fish in the lake toba.

Abstract

Soft coral extract of Lobophytum sp. can inhibit the growth of pathogenic bacteria with a weak to very strong category. The purpose of this study was to determine the activity of Lobophytum sp. against pathogenic bacteria E. coli, S. aureus, and P. aeruginosa and analyze the concentration of Lobophytum sp. effective against pathogenic bacteria E. coli, S. aureus, and P. aeruginosa. Sampling was carried out in the waters of Pigago Island, West Pasaman Regency, West Sumatra. This research method is an experimental method and antibacterial activity test is carried out with agar diffusion diffusion technique. This soft coral extract has the potential to inhibit pathogenic bacteria. The highest inhibitory effect on E. coli bacteria was the highest yield at a concentration of 100% with a yield of 13.95 mm, in the S. aureus bacteria the highest yield at a concentration of 100% with a yield of 12.53 mm and in P.aureginosa bacteria at a concentration of 100% was 23.87 mm.

Abstract

Riau Province has many lakes and reservoirs, one of which is the Koto Panjang Hydroelectric Reservoir, Sustainability of the Koto Panjang Hydroelectric Reservoir Unstable water continuity, drought during the dry season and flooding during the rainy season have caused this power plant to be not optimal, one of the ways that can done to overcome complications in certain areas. Koto Panjang Hydroelectric Reservoir Water is that by using the analysis of the Koto Panjang Hydroelectric Reservoir we can arrange steps in managing the maintenance of the Koto Panjang Hydroelectric Reservoir. Sustainability analysis conducted using the RAP-catchment area application on three dimensions, namely ecology, economics and social, the results of the analysis that have been carried out on the ecological dimension address an index of 52.31 which is classified as quite sustainable in the social dimension category 41.98 which is classified as less sustainable. To improve the index of sustainability in the management of water areas, several management directives are needed, namely reforestation or greening of open land related to rivers and conducting training in environmentally friendly agriculture to provide and support the protection of farming communities and communities related to fire, develop the potential of natural resources such as tourist attractions as alternative livelihoods to increase community income and increase socialization and encourage people in need in hydropower reservoir catchment areas.

Abstract

Tapanuli Tengah and Sibolga are one of the producers of small pelagic fish in the waters of West Sumatera. Spatial information on estimating the potential of small pelagic fish in the waters of Central Tapanuli and Sibolga is needed to determine the sustainability of the fish and make it easier for fishermen to catch fish. This research was conducted in February-April 2020 by utilizing secondary data from the North Sumatra Province Fisheries and Maritime Service in 2010 - 2015 in the preparation of the Coastal and Small Islands Zoning Plan (RZWP3) in 2016. The result showed the potential of small pelagic fish that exist in Tapanuli Tengah and Sibolga waters there are 18 species with a total volume and value of production, namely: Sibolga is 23,699.2 Tons (Rp.382.45 Billion) and Tapanuli Tengah is 16,921.8 Tons (Rp. 254.37 Billion). Estimation of fish abundance in Tapanuli Tengah and Sibolga waters are classified in Medium and High. The types of fish in Tapanuli Tengah waters are: Restrelinger spp, Selaroides leptolepis, stolephorus commersoni and Mugil Sp. Whereas in Sibolga waters the types of fish that are classified as having high abundance are Stolephorus commersoni, Decafterus ruselli and Dussumeiria spp, while Restrelinger spp and Selaroides leptolepis classified is medium

Abstract

Thalasina anomala is a type of shrimp that is generally found in the muddy areas of the mangrove area on the coast of the Selat Panjang. The purpose of this study was to obtain the chemical composition of meat and carapace and the rendemen of T. Anoma. Meat and carapace as raw material. This research method description and data analyzed statistically. In this study, there are two stages, namely preparation and rendement of body parts of rama shrimp and then proximate analysis of meat and carapace. Proximate test results from meat and carapace of successive shrimp are water content 76.58 %, 38.93 % gross weight (gw), protein content 81, 46 %, 10.12 % dry weight (dw) , fat content of 5.01% (dw), 2.36% (dw), ash content of 3.93% (bk), 73.96% (dw) and Carbohydrates 9.61% (dw), 14.62% (dw). This value shows that protein in meat is beneficial in food, while carapaces ash content shows the high mineral content
