Journal of Aquatropica Asia (JoAA) is an open access scientific periodical managed by the Department of Aquaculture, Bangka Belitung University. JoAA Journal involvement is carried out 2 (two) times a year, namely in July and December in the form of the main manuscript is an article that contains the results of research (research articles). Other manuscript contributions can be in the form of short articles (short communication), articles review, and also special issues. Articles received will be reviewed by reviewers managed by the Editor in Chief before the manuscript is accepted and approved for publication in JoAA. The Journal of Aquatropica Asia (JoAA) accepts articles written in Indonesian or English with regard to aquaculture studies and aquatic ecology in the broadest sense covering aspects of reproduction, nutrition and feed, genetics, physiology, morphology, health of aquatic organisms, water quality, plankton, conservation, and other aspects relevant to the field of aquaculture.

Abstract

Macrozoobentos is one of the basic organisms of waters associated with the seagrass ecosystem. This study aims to determine the correlation between the density of Macrozoobentos and seagrass cover in the seagrass ecosystem in the waters of Panjang Island. Sampling was done during lowest tide periode by a quadrat transect method consisting of 3 transects and spanned 50 from coral reefs to coastal areas. The results obtained 83 Type Macrozoobentos of 8 Classes with a total of 4,097 ind. The type of seagrass found on Pulau Panjang consists of Cymodocea rotundata, Thalassia hemprichii, Halophila ovalis, Halodule uninervis, Syringodium isoetifolium and Enhalus acoroides, average seagrass density of 6 stations in Panjang Island waters ie Thalassia hemprichii 644 / m2 and The lowest is the seagrass type Enhalus acoroides 76 stands / m2.

Abstract

Communities on the island of Bangka use soil ponds and floating net cages on ex tin mines lake for tilapia cultivation. Currently, the comparison of the productivity of the two cultivation system for Tilapia cultivation is not known. This study analyzed the business and productivity of tilapia rearing under floating net cages and soil ponds in Air Mesu Village, Pangkalan Baru District, Central Regency. The method used in this study is a survey method with case study techniques with data collection through interviews, questionnaires, and observations. Overall, the business of rearing Tilapia with the KJA system and soil ponds in Air Mesu Village is feasible to develop because the R/C ratio is >1. The use of the KJA system has an R/C ratio and greater productivity than the ground pool. Yield productivity of 25.12 kg/m2 in the KJA system and 19.52/m2 in the soil pond system.

Abstract

The rationale for using medicinal plants or herbs makes their use seen as playing an important role in the prevention and treatment system at the present time. Utilization of medicinal plants in combination is considered more effective and has a higher antibacterial activity compared to a single extract. One of the herbal medicine products from the combination of kencur medicinal plants (Kaempferia galanga) and thatch (Imperata cylindrica) under the name Meddia Meddwa its antibacterial activity has been assessed. This study aims to analyze the effectiveness and antibacterial activity in vitro, and the best concentration from the combination of kencur and kalang in Jamu Meddia Meddwa against Gram positive bacteria ( S. aureus) and Gram negative (A. hydrophila). This study also analyzed the content of active compounds or phytochemicals contained in the combination of kencur and thatch in Meddia Meddwa Medicines. The research method used is a laboratory experimental method. This study uses a single complete randomized design (CRD) with a tukey test. The results showed that the combination of kencur and kalang in Meddia Meddwa herbal medicine had antibacterial activity in vitro. Inhibitory zone diameters for all extract concentrations tested on A. hydrophila and S. aureus significantly different results were obtained (P ≤ 0.05). Gram-positive bacteria (A. hydrophila) effectively inhibits bacterial growth compared to Gram negative bacteria (S. aureus). The content of active compounds contained in the combination of kencur and thatch in simplicia Meddia Meddwa is alkaloids, flavonoids, steroids and phenol hydroquinone. The best concentration of simplicia kencur and thatch in Meddia Meddwa herbal medicine in inhibiting bacterial growth A. hydrophila and S. aureus is 6 ppt.

Abstract

The one of Belitung Island’s native fish which has important economic value is Cempedik fish (Osteochilus spilurus). Its consumption, which still relies on natural catchments, requires a study of its biology and ecology. One of the studies that have never been studied in the maturity of this species is the relationship of fecundity with fish weight - length and gonad weight. This study used samples of Cempedik fish from the Lenggang River, East Belitung which were obtained randomly from the catches of fishermen. Sampling adjusts the fishing season that occurs in the rainy season. The preparation was carried out on whole fish using 4% formalin. Calculation of fecundity gravimetrically and compared with fish lengths and gonad weights in the graph. Fecundity in 2015 was 222 – 10,947 eggs and in 2016 there were 335 – 2,060 eggs. Fish body length and weight affected the fecundity of the 2015 fish sample but had no effect on the 2016 sample. This is predicted to occur due to differences in sampling time to position and rainfall in the rainy season, availability and suitability of natural feed, and changes in habitat quality. Gonadal weight correlated with fecundity, where the higher the gonadal weight, the higher the fecundity. Keywords: Cempedik, rainy season, maturity, fecundity.

Abstract

Tilapia (Oreochromis sp.) is a consumption fish inhabiting freshwater and likeability by society. Tilapia’s benefits can attract breeders to cultivate in mass-producing with very high market demand. Every mistake that occurs in aquaculture activities is usually the feeding management which can cause various problems, such as damage to water quality that can trigger growth—diseases, including Motile Aeromonas Septicemia (MAS) caused by Aeromonas hydrophila. The use of Canbat assumed there are contain some antioxidants that can be used as immunostimulators to increase the survival of tilapia. This research aimed to find out the concentration of Canbat product PT. Meddia herbal is effective for the treatment of tilapia (Oreochromis sp.) infected by Aeromonas hydrophila bacteria. The method used in this research was experimental. The size of tilapia used is 10-11 cm with a density of 10 fish/container. The treatment doses used were P1 (40 ppm), P2 (60 ppm), P3 (80 ppm), Positive control (Amoxicillin), and Negative control (0 ppm), with 2-hour immersion. The parameters observed were clinical symptoms, fish survival, fish response to feed, and absolute weight growth. The results indicated that herbal Canbat with concentration (80 ppm) was effective in treating tilapia infected with Aeromonas hydrophila bacteria; it produces the fastest recovery of clinical symptoms on the 12th day and the highest survival rate of 90%.
