      Abstract: 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.

    • Authors: Nova Ulhasanah, Ariyanti Sarwono, Michael Yosafaat, Dennis Filippi, I Wayan Koko Suryawan, I Made Wahyu Wijaya
      Pages: 8 - 12
      Abstract: 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.

  • A Comparison of Eucheuma cottonii Seaweed Cultivation in Monoculture and
           Polyculture Systems

    • Authors: Putri Febrine Nainggolan, I Wayan Arthana, Ayu Putu Wiweka Krisna Dewi
      Pages: 13 - 18
      Abstract: 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.

  • Heavy Metal Content of Pb and Cu in Wideng Crab (Episesarma sp.)

    • Authors: Suprabadevi Ayumayasari Saraswati, Endang Wulandari Suryaningtyas, Ni Putu Putri Wijayanti
      Pages: 13 - 16
      Abstract: 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

  • Study Of Macrozoobentos Diversity In The Secondary Flow Of The Bengawan
           Solo River

    • Authors: Agung Pamuji Rahayu, Norma Aprilia Fanni
      Pages: 23 - 29
      Abstract: Macrozoobenthos are invertebrate animals that live on the bottom of the waters which are often used as an estimator of the imbalance in the physical, chemical, and biological environment of the waters. Polluted waters will affect the survival of macrozoobenthos organisms because they are easily affected by the presence of physical and chemical pollutants. This study aims to determine the diversity, abundance of macrozoobenthos as well as diversity index, evenness index, dominance index, and density index which can be used as a reference for determining the water quality of the Bengawan Solo River secondary flow in Tunjungmekar Village, Kalitengah District, Lamongan Regency. Researchers found 6 classes of gastropods, 1 class of bivalves, 1 class of crustaceans, 1 class of malacostraca, 1 class of clitella, from 10 types of macrozoobenthos. It is known that the diversity values ''of stations 1,2,3 and 4 are included in the low category, this is because the value of each station is <1. The evenness value of stations 1,2,3 and 4 is included in the low category because each station is <1. From the results of the dominance analysis, the highest value is at station 1 with a total of 0.59 because there are freshwater snail species that dominate at station 1. The highest value density is at station 1 with a value of (40.49) while the lowest value is at station 4 with a value of (2, 83). The highest density value is at station 1 with a value of (40.49) while the lowest value is at station 4 with a value of (2.83). The result water quality temperatures between 28.5-300C, brightness ranges from 19-21 cm, depth ranges from 0.5 - 2 m, the salinity of 0‰, pH from 8.5-8.8, dissolved oxygen (DO) ranged from 2.2 to 3.3 mg/L, nitrite ranged from 0.09-0.20 mg/l. The results of water quality measurements are still in good condition for the life of aquatic biota.

    • Authors: Felicia Augustine, Ni Luh Watiniasih, Ni Made Ernawati
      Pages: 30 - 35
      Abstract: The research was conducted in Dreamland beach, Pecatu Village, Bali. The purpose of this research is to identify the potential and the tourism suitability index of Dreamland beach. The research was carried out from the start of January to the end of February 2021. The method used for this research is the descriptive quantitative method. Furthermore, the researcher uses the purposive sampling method to group the location into three location points. There are three points measured in the tourism suitability index, including depth, type of beach, the width of the beach, the base material of the water, slope of the beach, current velocity, brightness, beach land cover, dangerous species, and availability of freshwater. The research shows Dreamland has various potentials such as white sand, big waves, and moderate sloping cliff which enables visitors to enjoy the sunset. As a tourist destination, Dreamland is equipped with several facilities including restaurants, toilets, and kiosks. Moreover, visitors can rent umbrellas and surfing boards. Additionally, for safety purposes, there will be a lifeguard on duty. Access to Dreamland is easy, it has two parking spots. Parking spot 1 is designated for motorcycles, whereas parking spot 2 is designated for cars and buses. Based on this research, Dreamland achieved a good Tourism suitability index at 2.51 at locations 1 and 2.59 at locations 2 and 3. The parameters which act as the limiting factors are the current velocity and brightness. High-velocity current results in the mixture of sedimentation and seawater which leads to murky water, thus low visibility rate.
