The Morosari estuary area is an estuary area consisting of aquaculture areas, mangrove areas, tourist areas, and several large-scale industrial and household activities. This situation causes the entry of waste containing heavy metals (Pb and Cu) into the estuary area. Wideng crab (Episesarma sp.) is one of the biotas that lives in the area and is influenced by the presence of heavy metals (Pb and Cu). This study aims to determine the content of heavy metals Pb and Cu in the mouth of the Morosari River and in the meat of the Wideng Crab (Episesarma sp.). The research was conducted in April – June 2009 and located at the mouth of the Morosari River (Demak). The research method used is a descriptive exploratory method, while sampling using purposive random sampling was conducted at 3 stations. A sampling of Wideng Crabmeat (Episesarma sp.), water, and sediment was carried out every 2 weeks as many as 5 samples and continued with analysis at the Central Laboratory of Kopertis Growth Region IV Semarang. Furthermore, the data obtained were analyzed descriptively. The results of the analysis of the Pb content in water were 0.039 - 0.089 mg/l, and the content in crab meat was 0.175 - 0.335 mg/kg. While the content of Cu in water is 0.024 - 0.055 mg/l, and in crab meat 0.032 - 0.16 mg/kg. The value of heavy metal content in the water has exceeded the quality standard threshold allowed by the Ministry of Environment Number 51 of 2004

The generation of organic waste is one of the biggest problems in developing countries like Indonesia. Examples of organic waste that can be obtained, such as leaves, include banana leaves and coconut leaves. One way to process waste that can generally be done is by composting. In the composting process, a bioactivator such as EM4 is needed to accelerate the reaction process in the waste. This study aimed to determine the effectiveness of EM4 bioactivator in the degradation process of banana leaf and coconut leaf waste. Measurement of processing quality is measured in-situ with parameters of temperature, pH, and humidity. The waste temperature increased above 32oC for the addition of EM4 bioactivator, while without the addition of bioactivator it only increased to 31oC. pH tended to be in normal conditions and was in an acidic state on day 12. Humidity decreased from the beginning of the waste process to the end of the process. The final result of composting quality has met the criteria of SNI 19-7030-2004. There was also a decrease in the C/N content during the process, adjusting to soil conditions. The decrease in the value of C/N on the addition of bioactivator also influences the composting process.

Viral Nervous Necrosis (VNN) is a Nodaviridae virus-infected snapper and grouper fish, especially in the larval and seed stages targeted eye and nervous organ. Abnormal swimming was shown by fish behavior at the bottom pond. This study aimed to compare the identification of VNN through three different methods of RNA extraction from the organ target and amplification was carried out by Reverse Transcription of cDNA followed by Polymerase Chain Reaction (PCR) and quantitative real-time PCR (qPCR) technique. Herein, The RNA target from the organ from VNN-positive grouper fish samples targeted RNA2 region with 230-bp in electrophoresis gel and 69-bp by TAM-probe from qPCR were successfully converted and amplified from all RNA extraction kits. Different results of VNN amplified-cDNA were RNA extraction methods-dependent. Amplification using Tri Reagent® extraction kit showed the best result, with a large amount of RNA genome with good purity and showed clear results from PCR and qPCR. Furthermore, the sensitivity of RNA extraction methods was different from 50-100 ng total RNA/reaction. It was concluded that all RNA extraction kits can be used for the detection of the VNN genome by PCR and qPCR technique while resulting in different RNA yields. Overall, this study offers suitable methods to extract the VNN genome from grouper fish.

Seaweed is a commodity that has high economic value and benefits. The implementation of seaweed cultivation is quite short and the export market opportunities are wide open because the need for seaweed is quite large. This study aims to determine the growth rate of seaweed with monoculture and polyculture cultivation systems and the survival rate of abalone in polyculture cultivation. The research used an experimental method with Completely Randomized Design (CRD) consisting of two treatments and three replications. The cultivation system in this study was seaweed monoculture Eucheuma cottonii with an initial weight of 100 gr and 100gr seaweed polyculture with abalone Haliotis squamata, each polyculture culture net bag containing 50 abalones. The value of the specific growth rate of monoculture seaweed was 2.21%/day, lower than the specific growth rate of polyculture, which was 3.61%/day. T-test analysis showed the value of sig = 0.049 < = 0.05, which means that there is a significant difference between the treatment of monoculture cultivation and polyculture cultivation. The abalone growth rate value ranged from 0.78-0.91%/day and the abalone survival rate ranged from 68-76%. Changes in environmental conditions affect the condition of abalone and seaweed so that the survival value of abalone is quite low and seaweed is infected with an ice-ice disease which causes a decrease in seaweed weight gain in the final week of the study period.

Aquaculture is an activity to develop, obtain, reproduce and produce a fishery with the help of human resources. One of the cultivation practices is wader fish (Rashbora argyrotaenia) which is known for its very slow growth and relatively small size. This study aims to determine the growth rate of wader fish with different feeds in Blado Kulon Village, Tegalsiwalan, Probolinggo. The feed used was feed A in the form of fish pellets as a control, feed B consisting of a mixture of conch flour, soybean flour, bran, and tapioca flour, while feed C consisted of a mixture of conch flour, cassava leaf flour, bran and tapioca flour. The study was conducted for 42 days. The parameters measured in this study were temperature, DO, and pH, as well as observing the growth in absolute weight, specific growth rate (SGR), survival rate, and feed concentration ratio (FCR). Observations were analyzed using One Way Analysis of Variance (ANOVA) and further tests were carried out using the Duncan test. The results showed that different feeding did not have a significant effect on growth rate, absolute weight, feed conversion ratio, and survival of wader fish. Water quality parameters measured include temperature with an average of 28.42oC - 28.54 oC, while pH has an average of 7.42 - 7.50, and dissolved oxygen (DO) with an average of 5.54 - 6, 23 mg / L.

In supporting fishery activities, Nusantara Fishing Port Pengambengan is currently supported by various facilities, namely basic facilities, functional facilities, and supporting facilities. The results showed that there were several facilities in poor conditions, namely basic pier facilities, anchoring ponds, complex roads, and drainage, from supporting facilities, namely public toilets and guest houses. Several facilities are not available in the Nusantara Fishing Port Pengambengan construction, namely ship docks, net repair wards/places, laboratories, WWTPs, watchtowers, and perimeter fences. The strategies obtained from the results of this study include: (1) Improving the quality of the catch to provide a positive image for potential investors. (2) Improve administrative services to provide fishermen comfort when carrying out fishing operations. (3) Support is needed, especially the role of the government related to management and development.","PeriodicalId":432816,"journal":{"name":"Advances in Tropical Biodiversity and Environmental Sciences","volume":"46 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128930212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was conducted to determine the condition of the mangrove ecosystem based on its canopy cover and to determine the types of mollusks (Bivalves and Gastropods) associated with the Benoa Bay mangrove ecosystem. Hemispherical photography is a method for observing mangrove canopy cover and line transect method for mollusks. The composition of mangrove species found in the research location were five species, namely Rhizophora stylosa, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, and Avicennia marina. The percentage of mangrove canopy cover in the Benoa Bay mangrove ecosystem is in a good category (average = 76.59%). There are eight types of mollusks found in the research location. There are two types of bivalves (Polymesoda bengalensis and Gafrarium pectinatum) and six types of gastropods (Nerita balteata, Nerita picea, Neritina turrita, Pila ampullacea, Cassidula aurisfelis, and Littoraria melanostoma). The relationship between the percentage of mangrove canopy cover and abundance of mollusks in the Benoa Bay mangrove ecosystem is very strong (r) of 0.920. The higher the percentage value of mangrove canopy cover, the higher the mollusks abundance.

Problems in the fish hatchery sector often occur such as high egg mortality or low quality of fish eggs. Optimizing biosecurity is one of the efforts to improve the quality of fish eggs, for example by adding disinfectants such as iodine, ozone, and peracetic acid. The use of chemical disinfectants will produce good results if the right dose, time, and commodity are used. In this study. This research aims (1) to determine whether the use of chemicals including iodine, ozone, and peracetic acid had an effect as a disinfectant to increase the hatching rate of grouper fish, (2) to determine the level of effectiveness and efficiency of the use of chemicals as a disinfectant. This research is an experimental research type. The research subjects included in the study were cantang grouper fish eggs at PT. Pakarti Daksa Segara who used the exploratory sampling method. The conclusion of this study indicates that there is an influence on the growth rate of the use of iodine, ozone and, peracetic acid chemicals as disinfectants of cantang grouper eggs and there is a comparison of the effectiveness and efficiency of the use of the three chemicals which includes the percentage of the hatching rate, the cost of the disinfectant material and the time, which is needed in the use of the disinfectant.
