Abstract

Vibrio parahaemolyticus is a gram-negative halophilic bacterium that lives in estuaries and beaches. These bacteria are agents that cause septicemia in shrimp during the larval and post larvae period. This study aims of this experiment is to determine the effect of mangrove leaf, root, stem and fruit extracts of Rhizophora stylosa growth of the V. parahaemolyticus bacteria. The experimental design used a completely randomized design (CRD) with positive control treatment (Papper disk containing chloramphenicol); Negative control (Papper disk containing methanol) P1 = mangrove extract 100 mg/L; P2 = 200 mg/L mangrove extract; P3 = 400 mg/L mangrove extract and in doing it on 3 times. The research parameter was measuring the bacterial inhibition zone. The results showed that the mangrove leaf, root, stem and fruit extracts of R. stylosa significantly affected on the inhibition zone and of high concentrations of the leaf, root, stem extract concentrations of R. stylosa mangrove fruit, the wider the bacterial inhibition zone. The concentration of 400 mg/L extracts of leaves, roots, stems and fruit heads of R. stylosa mangroves was the most effective concentration to inhibit the growth of V. parahaemolyticus bacteria, which showed an average root inhibition zone of 9.5 mm, leaves 7.7 mm, stems 6.5 mm, and fruit heads 4.8 mm.

Abstract

Macrozoobenthos has an important role in ecological functions in mangrove ecosystems which can be used as bioindicators in aquatic ecosystems. The purpose of this study was to inventory macrozoobenthos, water quality and substrate found at the study site. The method used in this study was the observation transect method of mangrove vegetation measuring 10 x 10 meters in which 5 sub-plots were made in the plot where each sub-plot measuring 1 x 1 meter. Macrozoobenthos samples were taken from the substrate, stems and roots of mangroves. Measurements of water quality parameters were taken in situ at each research station and the substrate was taken using a shovel and then observed for sediment particles in the Dumai Maritime and Fisheries Polytechnic laboratory. This study succeeded in infentarizing the macrozoobenthos of the Mollusc Phylum, class Gastropods with 6 families and 6 species (Nerita articulata, Chicoreus capucinus, Littorina scabra, Ellobium aurisjudae, Cerithidae quoyii and Pugilina cochlidium) and class Bivalvia, 1 family and 1 species (Polymesoda bengalensis). Water quality parameter values consist of an average temperature of 29.73 ˚C, a salinity of 26.33 ppt, dissolved oxygen (DO) 4.92 mg/l and a pH of 6.9. This water quality condition can still be tolerated by mangrove and macrozoobenthos plants. Substrate texture at stations 1 and 2 includes the clay loam category and station 3 the sandy loam category which has an influence on the abundance of macrozoobenthos.

Abstract

Tilapia fish Oreochromis niloticus is one type of freshwater fish that is widely cultivated by farmers. Cultivation of tilapia in drums (budikdamrum) has the potential to be carried out on limited land by feeding maggot. This research was conducted to evaluate the feeding of maggot (Hermetia illucens) combined with natural ingredients on the growth and feed conversion ratio of tilapia based on budikdamrum technology. The study was carried out with 2 treatments, namely DP (fish fed with maggot 10 g/day + natural ingredients in the form of Moringa leaf flour (Moringa oleifera), garlic flour (Allium sativum), tapioca flour), and DK (fish fed pellets of 10% biomass/day without natural ingredients). Kale plants were grown in 5 cups filled with foam and activated carbon mounted on the top of the drum. Fish were kept for 25 days, and sampling was done every 3 days. The results showed that the growth of tilapia in DK was higher than DP (P<0.05). Specific growth of fish weight 6.01±0.13 – 7.13±0.04% and length 1.90±0.06 – 2.42±0.32 cm. absolute growth of fish weight 4.67±0.03 – 6.62±0.89 g and length 2.85±0.10 – 3.73±0.44 cm. The feed conversion ratio did not show any difference between DP and DK (P>0.05), namely 1.26±0.08 – 1.38±0.19. The survival rate of tilapia treated with DP was higher than DK (P<0.05) with a range of 89±4.90 - 98±2.83%. The water quality obtained in this study was included in the category of requirements for tilapia cultivation. The application of the budikdamrum technology is recommended for rearing tilapia with maggot feed as additional feed mixed with natural ingredients.

Abstract

Salinity is the level of saltiness or salt content dissolved in water. Salinity is the total concentration of dissolved ions in water. The amount of salinity greatly affects the growth and survival rate of biota in the waters. To find out the salinity can be done by direct measurements in the field or by modeling. The purpose of this study was to determine the value of the salinity parameter by modeling salinity using the MIKE-21 Software at the mouth of the Citanduy River, Pangandaran Waters. MIKE-21 software is a hydrodynamic modeling software used to predict marine physics parameters, one of which is the value of the salinity parameter. The results of salinity modeling carried out at 4 observation stations at the mouth of the Citanduy River obtained an average value of salinity at high tide at the mouth of the river was 17.05 ppt and at low tide was 14.31 ppt.

Abstract

Pangandaran Regency is famous for its natural beauty and favorite tourist destination in West Java, but it also has the potential for earthquakes and tsunamis due to its proximity to the Indo-Australian plate subduction zone. Pangandaran has a history of the 7.7 magnitude earthquake with the tsunami in 2006, to anticipate it again a mapping model is needed related to the vulnerability of the tsunami disaster in Pangandaran in the form of a vulnerability map as well as conducting a survey of vulnerability locations on the coast of Pangandaran. The zoning method is described descriptively using satellite imagery and direct observation, satellite imagery data analyzed are data on slope, elevation, land use, distance from the river and distance from the coastline. The tsunami hazard along the coast of Pangandaran Regency is relatively different from one zone to another, because it is influenced by parameters of morphology, bathymetry and coastal topography. Indicators of coastal slope and bottom of coastal waters play an important role in the magnitude of the potential for a tsunami in a zone, the zoning results show that the Pangandaran coastal area may be directly affected by tsunami waves. The following are high-risk zones which are areas with low altitudes such as the sub-districts: Kertamukti, Ciparanti, Legokjawa, Cijulang, Parigi, Karangbenda, Cibenda, Sukaresik, Wonoharjo, Pananjung, Babakan and Bagolo. These sub-districts need to install signs of tsunami vulnerability in the event of an emergency, it is also necessary to conduct outreach and training on preparedness in the event such as an earthquake and natural signs related to a tsunami or post-tsunami.
