Abstract

 Vibriosis disease Vibrio harveyi often drops Penaeus monodon production on the traditional coastal ponds of North Kalimantan. The purpose of this study was to find out the active compound extract of Sonneratia alba fruit inhibiting the infection of Vibrio harveyi, which was tested on the larvae of Penaeus monodon in post larvae 12 through the bioerichment of natural feed Artemia salina. This study used an experimental method performed with a Completely Randomized Design (CRD) of 4 treatments and 3 replications. The results showed mangrove fruit extracts containing alkaloids, phenol hydroquinone, flavonoids, saponins, steroids and tannins. Artemia salina bioenrichment succeeded in increasing the survival of Penaeus monodon larvae 78.33% in treatment III (20 ppm). The results of water quality measurements indicate the range at the normal limit for the life of the Penaeus monodon larvae. Keywords : Penaeus monodon, Artemia salina, Vibrio harveyi, Extract Sonneratia alba

Abstract

This research was the administration of papaya seed extract to black tiger prawn which were challenged with Vibrio harveyii infection in vivo and in vitro to determine the effectiveness of papaya seed extract in inhibiting vibrio harveyii. This research was conducted in the laboratory of the Faculty of Fisheries and Marine Sciences, University of Borneo Tarakan in vitro and in vivo. The data obtained were analyzed descriptively and statistically. Based on observations and research it is known that papaya seed extract (Carica papaya) in vitro contains active antibacterial ingredients such as saponins, flavonoids which can inhibit Vibrio in breeding so that it has an impact on the weakness of Vibrio harveyii in disturbing and inhibiting the growth of tiger shrimp larvae during independent research. in vivo. The survival rate of black tiger prawn larvae from the total of each treatment which was maintained for 12 days of treatment showed that the highest value was achieved in treatment P3 of 90% and the lowest was obtained in the negative control treatment of 5%, while in treatment P1 (positive control) of 95 %, P4 was 78% and P2 treatment was 65%.

Abstract

Seaweed is one of the fisheries commodities that is widely cultivated in Indonesia. The cultivation of seaweed (Kappaphycus alvarezii) in the Coastal Waters of Amal Baru, Tarakan City, is traditionally done using the longline method. The gillnet method is the most used method by seaweed farmers because it is flexible in choosing locations and relatively inexpensive. The research aims to determine the difference in the number of seaweed seedlings on the absolute and specific growth rates. This study used a Completely Randomized Design (CRD) with 4 treatments and 3 replications. Treatment P1 (1 bundle), P2 (2 bundles), P3 (3 bundles), and P4 (4 bundles). The results showed that the growth of seaweed seedlings with different numbers of bundles influenced absolute and specific growth rates. The best treatment was found in treatment P4 with an average absolute growth rate of 80.00% and an average specific growth rate of 100%.

Abstract

Seaweed farming needs essential nutrients for growth. Nitrate and phosphate are essential nutrients for the growth of seaweed algae and phytoplankton produce chlorophyll-a. Chlorophyll-a content is needed in the photosynthesis process and triggers seaweed metabolism to absorb more nutrients. This study describes the relationship between nitrate, phosphate, chlorophyll-a for west and east monsoon waters with other water quality parameters in Tarakan Island. Insitu and exsitu measurements of water quality samples at 14 stations were determined by stratified random sampling in March 2024 for the west monsoon and June 2024 for the east monsoon. The distribution of chlorophyll-a was obtained from observations of the JAXA GCOM-C OCEAN CHLA V3 satellite image and the ocean contour model from BIG. There are significant differences in the distribution of chlorophyll-a, phosphate, and nitrate in the west and east monsoons. Chlorophyll-a distribution in the west monsoon of 0.60-1.10 mg/m3 tends to be higher than that in the east monsoon of 0.50-0.85 mg/m3 divergent pattern and correlates with nitrate, phosphate, water brightness, turbidity, sea surface temperature, current and pH. Water quality in the east and west monsoons supports seaweed farming.  Budidaya rumput laut membutuhkan nutrien penting untuk pertumbuhannya. Nitrat dan fosfat merupakan nutrien penting untuk pertumbuhan algae rumput laut dan fitoplankton penghasil klorofil-a perairan. Kandungan klorofil-a dibutuhkan pada proses fotosintesis dan memicu metabolisme rumput laut menyerap lebih banyak nutrien. Penelitian ini menjelaskan keterkaitan nitrat, fosfat, klorofila-a perairan musim angin barat dan timur bersama parameter kualitas perairan lainnya di Pulau Tarakan. Pengukuran insitu dan exsitu pada 14 stasiun ditetapkan secara stratified random sampling bulan Maret 2024 mewakili musim angin barat dan Juni 2024 musim timur. Distribusi klorofil-a diperoleh dari pemantauan citra satelit JAXA GCOM-C OCEAN CHLA V3 dan pemodelan kontur laut dari BIG. Terdapat perbedaan signifikan distribusi klorofil-a, fosfat dan nitrat musim angin barat dan timur. Distribusi klorofil-a perairan musim barat 0,60-1,10 mg/m3 cenderung tinggi dibandingkan musim timur 0,50-0,85 mg/m3 berpola divergen dan berkorelasi dengan kadar nitrat, fosfat, kecerahan perairan, kekeruhan, suhu permukaan laut, arus dan pH. Kualitas perairan musim angin timur dan barat mendukung budidaya rumput laut.
