  • The Effect of Fermentation Duration on Nutrition Composition of Seaweed
           (Sargassum sp.) Liquid Organic Fertilizer

    • Authors: Zakaria Zakaria, Andi Adam Malik, Khairuddin Khairuddin, Muhammad Ishak
      Pages: 1 - 11
      Abstract: This study aims to determine the effect of fermentation duration on the nutrient composition of seaweed liquid organic fertilizer (Sargassum sp). This research was conducted from May to June 2017 at The University of Muhammadiyah Parepare. Test materials used in the form of seaweed and lactobacillus. The container used in the implementation of this research is 6 bottles of 1000 ml size, before the bottles are used first the bottles are washed clean. Then each bottle is filled with extracts of Sargassum sp. as much as 800 ml and 40 ml of probiotics. Two bottles of treatment A (without fermentation), 2 bottles for treatment B (7 days fermentation), 2 bottles for treatment C (14 days fermentation). The design was a completely randomized design (CRD) with 3 types of each treatment. The results showed that micro nutrients that the iron (Fe) were obtained highest in treatment C (concentration 162 ppm), Silica (Si) in treatment A (100 ppm), manganese (Mn) in treatment B (29 ppm). For the highest macro nutrients potassium (K) obtained in treatment C (concentration 0.52%), Calcium (Ca) in treatment B (0.33%), Sulfur (S) in treatment C (0.31%) , Chlorine (Cl) in treatment C (concentration 0.27%). The research concludes that the length of time of fermentation affects the nutrient content of liquid organic fertilizer seaweed.

  • Utilization of Jatropha Leaf (Jatropa curcas) Extract as Immune System
           Enhancer of Vannamei Shrimp (Litopenaeus vannamei) Infected with Vibrio
           parahaemolyticus

    • Authors: Bagus Ansani Takwin, Dimas Putra Perdana, Muhaemi Muktiniati, Fariq Azhar
      Pages: 12 - 20
      Abstract: The problem arises in vanamei shrimp cultivation is the emergence of diseases, such as vibriosis caused by Vibrio parahaemolyticus. Jatropha leaf extract can be used as an immunostimulant because it contains bioactive compounds namely flavonoid, tannins, saponins, and alkaloids. This research used a completely randomized design (CRD) with 5 treatments with 3 replications. The treatments used were; P1 (feed without extract and bacterial infection); P2 (feed without extract and NaCl injection); P3 : Feed + 1% + bacterial infection; P4 : Feed + 2% extract from feed and bacterial infection, P5 : Feed + 3% extract of feed and bacterial infection. Based on the results of the study, the administration of Jatropha leaf extract was able to increase the highest SR value of P2 by 88.3%, the highest THC value of P5 at 24.46 x 106 cells/ml, DHC values ​​such as hyaline cells ranged from 36.67-71%, granular cells ranged from 17-38.57%, and semigranular cells ranged from 12-24.67%, the highest AF value in P5 was 77.25%, and the lowest TBC value was at P2 of 6 x 108 CFU/ml, the lowest TVC value was at P2 of 0.56 x 106 CFU/ml. The higher the dose of extract given, the higher the THC and AF, besides that, Jatropha leaves were also able to increase the SR value and suppress the growth of total bacteria and total Vibrio in shrimp intestines.

           System Dynamics Approach

    • Authors: Ade Kurniawan, Willem Hendry Siegers, Mohammad Aldrin Akbar, Imran Syafei M. Nur
      Pages: 21 - 30
      Abstract: The purpose of this study was to determine the survival rate (SR), the Average Daily Growth (ADG), and the Feed Conversion Ratio (FCR) of Nile tilapia (Oreochromis niloticus) with a dynamic system model. The dynamic system model is used to determine the optimal value of the three variables. The results showed that the survival rate, average daily growth, and feed conversion ratio of tilapia cultivation were 93% (SR), 3.2gr/day (ADG), 0.73 (FCR). In this research, tilapia production were 14,199gr, the amount of feed were 10.344gr and the length of cultivation were 65 days. It was hoped that the dynamic system model design could have tilapia farmers to develop aquaculture businesses that was more environmentally friendly, effective and efficient.

  • Suitability Assessment of Two Different Culture Systems for the Rearing of
           Clarias gariepinus Fingerlings

    • Authors: Ekaete Patrick Anwa-Udondiah, I. O. Soboyejo, O. A. Okunade, B. M. Lawal, A. S. Aboluwodi, O. V. Oyeniyi
      Pages: 31 - 37
      Abstract: This paper presents an experiment in which two different fish culture system types were evaluated for the short-term commercial culture of fingerlings of Clarias gariepinus maintained at half the recommended stocking rate; 82.5/m3 in 2 m3 water volume in indoor blue fiber-glass tanks (IFT) and outdoor black plastic tanks (OPT). The research objectives were to assess the suitability and commercial viability of the tanks. Initial mean body weight of graded fingerlings of C. gariepinus for IFT and OPT were 11.32±2.25 g and 10.92±2.44 g (mean±standard deviation) respectively. The study lasted for eight weeks with the fish attaining post-juvenile sizes of 174.95±74.30 g and 178.84±52.04 g (mean±standard deviation) in the IFT and OPT respectively which were not significantly different at p > 0.05. Survival at termination was 81.21±0.0% and 81.21±2.5% for IFT and OPT respectively. As fish attained larger sizes of 100 g and above between weeks 6 and 8, skin lesions and frayed fins were observed in comparatively more of the indoor reared fish than the outdoor reared fish. It may be concluded that the systems are not vastly different in terms of resultant survival and growth performance of the African catfish, however, the culture duration may be halved when maintaining the reported stocking rate in order to prevent distress as a fallout of aggression as they increase in size.

  • Effect of Maggot on the IL-6 and IFN-Ɣ Expression of Koi Fish (Cyprinus
           carpio) Infected with Edwardsiella tarda

    • Authors: Ida Ayu Kade Wimala Niti, Maftuch Maftuch, Rahmi Nurdiani
      Pages: 38 - 48
      Abstract: The increase in koi fish cultivation can lead to increase risks and caused problems. The main problem is high disease attacks caused by the bacteria Edwardsiella tarda. One of the alternatives to control the disease is immunostimulant treatment with the use of maggot, Hermetia illucens Larvae, known as Black Soldier Fly (BSF). This study aims to report the effect of maggot as a substitute for koi fish feed formulations on the immune system of koi fish infected with E. tarda. This study used a descriptive method, by quantitative approach with the IL-6 and IFN-Ɣ expression through RT-PCR analysis and fish survival rate (%). Identification of E. tarda was carried out by the PCR test method at a molecular weight of 200 bp. The density of bacteria that caused the death of the 50% koi fish population (LD50) for 72 hours was 107 cells/ml. The highest IL-6 expression in the spleen was found in sample C of 28,844 and the lowest in-sample K (+) of 26,096. The highest IL-6 expression in the liver was in sample K (+) of 29,060 and the lowest was in sample D of 25,428. The highest IFN-Ɣ in the spleen was in treatment C, 28,844, and the lowest was in treatment D, 27,219. The highest IFN-Ɣ in liver was sample K (+) of 26,795, and the lowest in-sample C of 25,615. The survival rate of fish in this study reached 30%-100%. The optimal amount of substitution of maggot treatment is 75% (Treatment C) of fish feed.

  • The Mitogen-Activated Protein Kinase (MAPKs) Expression and Primary Stress
           Hormone (Cortisol) of Clarias sp. Juvenile in Different Light Intensity

    • Authors: Agoes Soeprijanto, R Adharyan Islamy
      Pages: 49 - 56
      Abstract: Clarias sp. is one of major genera of freshwater catfish and also common commodity in tropical aquaculture. Excessive light intensity is expected to be responded to by fish as environmental stressors. Fish that experience stress will increase the secretion of catecholamine, cortisol, blood glucose levels and p38 MAPKs in catfish. The different intensity of lights will affect the fish physiological processes. The purpose of this study was to analyze physiological responses (Level of blood glucose, primary stress hormone (Cortisol) and p38 MAPKs) catfish Clarias sp. which were incubated at different lights intensity of catfish. 300 fish were collected from Kepanjen Regency, East Java. Blood and meat sampling are carried out to test the profile of glucose, cortisol, and p38 MAPKs. The experimental research at this stage were carried out by transferred the catfish from Kepanjen to experimental aquarium (50 x 30 x 30 cm) that setted the different lights intensity (0 lux (control), 400 lux, 800 lux and 1200 lux). Each experimental aquarium is filled with 15 catfish and will be kept it for 21 days. Quantificationof the parameter using ELISA method. The study result showed highest peak of primary stress hormone (cortisol) levels are 34±1,50 ng/mL, blood glucose levels are 120±3,4 mg/dL, and p38 MAPK are 97±1,1 %. All of it were achieved in the treatment of 1200 lux on the 2nd week.

  • Morphometric and Meristic Diversity in Eel (Anguilla bicolor) in South
           Coast of Java

    • Authors: Endah Rochmatika, Win Darmanto, Mufasirin Mufasirin, Ramadhana Ramadhana
      Pages: 57 - 69
      Abstract: Indonesia is the largest exporter of eel to consumer countries such as European, America, Taiwan, Japan, South Korea, and the Middle East. Eels are catadromous fish that are in the growth phase in fresh waters and the development phase is in marine waters. Meristic measurement is done by counting the spine (vertebrates). Eel morphometric measurements include TL (Total Length), HL (Head Length), PDL (Pre-Dorsal Length), PAL (Pre-Anal Length) and ADL (Ano-Dorsal Length). The purpose of this study was to analyze the morphological, morphometric, and meristic diversity of intraspecies between populations. Based on the research, the samples identified were morphologically almost the same between the populations, this was seen from the color patterns in the form of plain black or brown and short fins. The morphometric and meristic measurements in the 3D distribution plot still appear to be clustered in one population, while in the dendrogram clade, one species is still congregated in each. The results of the interpretation of the matrix plot of the lowest diversity are the length and number of anodorsal vertebrate segments. This observation can be concluded that the TL and TV of the eel varied, while the PDL, PAL, PDV, PAV, ADV showed the intraspecies character of A. bicolor. This is because the distribution of A. bicolor eels that inhabit the waters of Java Island is widely distributed and random (panmitic).

           Fos-Food Restaurant Business in the Pandemic Era; MICMAC Approach

    • Authors: Lina Asmara Wati, Riski Agung Lestariadi, Supriyadi Supriyadi, Muhammad Permana Hendra Safii
      Pages: 70 - 85
      Abstract: Talk about smart cities, the community's independence to open a business and drive the local economy is a concrete form in the community, which is useful in the current state. Even though in this Covid-19 pandemic condition, the life of a business is not easy, especially the seafood culinary business. A restaurant business requires a business development strategy that will determine the business's long-term future—this culinary tourism development and sustainability strategy. The MICMAC method functions analytically to solve systematic problems by developing sustainability strategies in industrial areas. So in this study, researchers will research Strategic Variable Analysis for the Development and Sustainability of the Fos-Food Restaurant Business in the Pandemic Era; MICMAC approach. This study uses primary and secondary data and uses the MICMAC method. The results of this study are: (1). The strategic factor analysis of Fos-Food Restaurant development has 11 strength variables, seven weakness variables, six opportunity variables, and eight threat variables. Based on the weighting and scores carried out, the total score for internal factors was 3.17 and for external factors was 3.07. (2). The research analyzed Fos-Food's development strategies and programs from the SWOT diagram, SWOT matrix, SWOT quadrant strategy analysis, and MICMAC analysis. The strategy analysis shows that the position of this restaurant is currently still in quadrant IV. Then the MICMAC analysis shows that judging from the indirect influence graph of each relationship between variables, the variables that have the greatest value are the variables: Financial and Accounting, Technological Environment, and Buyer/Customer Power.

  • Survival Rate and Growth Length of Catfish (Clarias gariepinus) Exposed to
           Microplastics

    • Authors: Diana Permatasari, Mohamad Fadjar , Ating Yuniarti
      Pages: 86 - 93
      Abstract: Aquaculture has a land potential of 17.92 million ha consisting of 2.83 million ha of freshwater aquaculture potential, 2.96 million ha of brackish water aquaculture and 12.12 million ha of marine aquaculture. One of the freshwater species that has the potential to be cultivated is catfish (C. gariepinus). But now, as a result of the decline in the quality of the freshwater environment, catfish are prone to contamination by plastic waste. If microplastic particles have accumulated in large numbers in the fish's body, it can clog the fish's digestive tract and affect the growth of catfish which will affect the results of aquaculture production. The purpose of this study was to determine the survival rate or survival rate of catfish exposed to microplastics. The research design used in this study was a Completely Randomized Design (CRD) with 1 control variable, namely no mixing of microplastics in commercial feeds and 3 different doses of microplastics, namely A (5%), B (10%), C (15%) mixed with commercial feed, where each treatment was repeated 3 times. The results of the one way ANOVA analysis showed that the treatment of exposure to microplastics with different doses did not have a significant effect (P<0.05) on the survival rate and length growth of catfish. The survival rate ranges from 65- 100%. Survival values that were not significantly different could indicate that there was competition for space and dominance of larger fish in the aquarium which affected fish growth, feed utilization and fish survival. Meanwhile, the length growth value ranged from 21-28cm. The length growth value which was not significantly different could indicate that the dose of microplastic used in the study did not result in muscle and bone cell division which was the cause of the increase in body length of fish.

  • Effect of Microplastic Exposures to The Male Gonad Histology of Catfish
           (Clarias gariepinus)

    • Authors: Anggita Noer Laily, Mohamad Fadjar, Yuni Kilawati
      Pages: 94 - 104
      Abstract: Aquaculture activities cannot be separated from obstacles that can lead to failure of aquaculture, including the presence of microplastics. Microplastic polystyrene (styrofoam) is a type of plastic that is commonly found in aquatic organisms (35%). Microplastics in fish can cause hormonal disturbances and high vacuolation in gonads which can cause apoptosis in gonadal cells. This study aimed to determine the effect of microplastics exposure on catfish (Clarias gariepinus) feed on the gonadal histology of male catfish. The research design used an experimental method with a Completely Randomized Design (CRD) which was divided into four treatments and three replications, namely 3% of the feed rate with treatments A (5% microplastics), B (10% microplastics), C (15% microplastics), and K (0% microplastics). Microplastic exposure treatment was given to fish by mixing it with commercial feed for 30 days. The results showed that microplastic exposure had a significant effect on the 15th and 30th days of the study on the Gonad Maturity Level (GML) and Gonado Somatic Index (GSI) of male catfish (C. gariepinus) in treatments A, B and C compared to controls (K). Treatment C (Microplastics 15%) had the lowest GML and GSI values, while treatment K (Microplastics 0%) had the highest GML and GSI values. Treatments A, B, and C experienced changes and delays in the development of gonadal cell structure, while control (K) developed well. This is presumably because the nutritional needs of control fish (K) were more fulfilled than treatments A, B and C exposed to microplastics.

      Abstract: Barriers to cultivation activities are disease attacks, one of which is caused by infection with the bacterium Edwardsiella tarda. Treatment efforts can be made using natural ingredients such as jackfruit (A. heterophyllus) leaves. This study aims to determine the content of antibacterial compounds in the jackfruit (A. heterophyllus) leaves crude extract and their effect on Edwardsiella tarda bacteria in vitro. The inhibition test used disc test with five different concentrations of jackfruit (A. heterophyllus) leaves crude extract with three replications: 75 mg/L, 150 mg/L, 225 mg/L, 300 mg/L and 375 mg/L with a comparison using two types of controls (positive with 5 mg/L chloramphenicol antibiotics and negative with no treatment) using Tryptone Soy Agar (TSA) media and incubated for 2x24 hours. The results of phytochemical screening proved that the jackfruit (A. heterophyllus) leaves crude extract contains flavonoids, alkaloids, tannins and saponins. Treatment E with a dose of 375 mg/L gave the highest inhibition of 7.80 mm and treatment A with a dose of 75 mg/L gave the lowest inhibition of 4.38 mm. The relationship between the treatment given to the test parameter in the form of the resulting inhibitory power obtained the equation y = 0.0111x + 3.6297 with an R2 value of 0.974 which means 97% of the treatment given in the form of crude extract of jackfruit (A. heterophyllus) leaves affects inhibition of bacteria E. tarda.

  • Strategy for the Development of Sustainable Vannamei (Litopenaeus
           vannamei) Shrimp Culture in Plastic Ponds in Tegal Regency, Central Java

    • Authors: Purwanto Purwanto, Sarjito, Dian Wijayanto
      Pages: 115 - 126
      Abstract: Vannamei shrimp culture is a fishery sub-sector that is being promoted by the Indonesian government. The vannamei shrimp culture great bussiness prospect makes many farmers to carry out these business activities. However, if the culture business is carried out in an environmentally unfriendly way, the sustainability of the business will stop. The purpose of this study is to determine the correct strategy for the development of vannamei shrimp culture in plastic ponds in Tegal Regency, Central Java. The research method used is the survey method with purposive sampling, the respondent sampling technique is non probability sampling and data collection with interviews, questionnaires, observation and documentation. The data obtained were analyzed descriptively and SWOT. The number of respondents was 38 people. The results indicated that the production of vannamei shrimp has decreased in the last three years due to Acute Hepato Pancreatic Necrosis Disease outbreak. A calculation matrix factor strategy internal (IFAS), strength (S) biggest are good and correct culture SOPs (0.349) and the calculation of the external strategy matrix (EFAS), opportunities (O) the largest is the large market goose p (0,293). Relationship factor occupy cell V, from effort the describe the situation growth and stability which means that the business is in a relatively stable condition and growth is likely to occur. Based on the SWOT analysis, the ranking of alternative strategies obtained is the SO strategy (Strengths – Opportunities) with total score of 3,602. Priority alternative strategy which used is optimizing the quality and quantity of products by using good and correct SOP, using technology, available infrastructure and availability of adequate seeds to produce quality and quantity of products so that continuity is maintained, so as to meet high market and consumer demand.

  • Antibacterial Activity of Red Galangal (A. purpurata) Extract on the
           Growth of E. tarda Bacteria

    • Authors: Desy Amalia Hidayati, Arief Prajitno, Titik Dwi Sulistyawati, Giri Pratama, Tania Nilakandhi
      Pages: 127 - 134
      Abstract: This study aimed to analyze the antibacterial activity of red galangal extract (Alpinia purpurata) against the growth of E. tarda. This aims of this study was to determine the antibacterial compounds and the antibacterial effectiveness of red galangal extract (A. purpurata) against the growth of E. tarda bacteria. Antibacterial activity test was carried out by MIC test and disc test. The MIC test used doses of 1 ppm, 10 ppm, 100 ppm, 500 ppm, and 1000 ppm with incubation for 24 hours. The disc test used doses of 100 ppm, 200 ppm, 300 ppm, 400 ppm, 500 ppm and a positive control of 5 ppm chloramphenicol and a negative control without treatment. Photochemical test of red galangal extract (A. purpurata) contains flavonoid compounds, alkaloids, tannins, triterpenoids, and saponins. The results of the disc test showed that the highest inhibitory diameter was 7.55 mm at a dose of 500 ppm and was bacteriostatic because it decreased its inhibitory zone after 48 hours of incubation. The highest inhibitory effectiveness was 56.56% at a dose of 500 ppm after 24 hours of incubation.
