Tigawaja fish (Nibea sp.) is a demersal fish that is commonly found in Indonesian waters. Tigawaja fish is a white-fleshed fish that contains about 18% protein, 0.03% total fat, vitamin A, niacin, calcium, and sodium. However, there are still few studies that discuss the growth characteristic of Tigawaja fish, hence, the management of Tigawaja fish resources cannot be optimized. Current study aims to determine the relationship between length and weight and condition factors of Tigawaja fish. Data collection was carried out at PPI Cikidang Pangandaran, West Java in February 2021. The field work method used random sampling of fish landed at PPI Cikidang Pangandaran. The parameters measured including the length and weight of the fish, and the data were analyzed descriptively. The results showed that the growth pattern of Tigawaja fish landed at PPI Cikidang Pangandaran was negative allometric with b value at 2.71. Regression analysis of the relationship between length and weight of Tigawaja fish resulted a coefficient of determination R2 of 85.69% indicating a very strong relationship between length and weight of Tigawaja fish. The results of the condition factor values have an average of 1.41 and relative weight with an average of 101.30. The results of the regression analysis of the relationship between condition factors and relative weight resulted a coefficient of determination R2 of 76.18% showed the relationship was very strong.Keywords: Tigawaja fish, length, weight, condition factor, relative weight, PPI Cikidang Pangandaran

The investigation on traditional salt production had developed in the characterization of Bittern. Bittern is the dense residual liquor with specific gravity ≥ 1.28 gr/cm3 obtained after precipitation and harvesting of NaCl salt from seawater. In this research, the measurment of sulfate in the bittern was carried out. Sulfate is one of the raw materials for MgSO4. The determination of sulfate concentration is using a turbidimetric method according to SNI 6989 20:2009 using a spectrophotometer at a wavelength of 420 nm. In this process the Sulfate in an acidic environment reacts with barium chloride (BaCl2) to form barium sulfate (BaSO4) crystals. The light absorbed by the barium sulfate suspension is measured with a photometer and the sulfate content is calculated by comparing the readings with the calibration curve. The results of the analysis showed that at 31o Baume the sulfate content is 40.0 g/L, at 32o Baume the sulfate content is 42.6 g/L, at 33o Baume the sulfate content is 42.8 g/L. The sulfate concentration in the bittern showed a linear increase with increasing water concentration. The sulphate content of bittern with 31oBe levels has an average value of 40.028 g/L, at 32oBe levels the average sulphate content is 42.599 g/L and at 33oBe levels it is 42,825 g/L. Keywords: Bittern, Sulfate, oBe

Natural feed must be available in order to give high-quality seeds to support aquaculture activities. Chlorella sp. is a natural food source for fish larvae and zooplankton. Chlorella sp. is more effective and efficient when stored in the form of floc. The purpose of this research was to obtain an effective dose of chitosan for flocculation of Chlorella sp. The study used a completely randomized design (CRD) with 5 treatments and 3 replications, i.e A. 150 mg L-1, B. 200 mg L-1, C. 250 mg L-1, D. 300 mg L-1, E. 350 mg L-1. The abundance of Chlorella sp. before and after flocculation measured as the main parameter. Water quality parameter such as temperature, pH, dissolved oxygen, total ammonia nitrogen, and nitrite function as supporting parameters. The results showed that the abundance of Chlorella sp. before flocculation increased from the beginning of stocking until the 6th day. The best results of the abundance of Chlorella sp. found in the C treatment (54.4-74.5%), then followed with B, A, D, and E treatments (31.2-55.1%, 22.8-51.2%, 19.0-45.6 %, and 13.3-44.6%) respectively. The most effective dose of chitosan in the flocculation process of fresh water Chlorella sp. was 250 mg L-1 with an abundance of 39.1x105 cells mL-1. Water quality in culture media of the Chlorella sp. showed that the range of measured values were still within the optimum range.Keywords: Abundance, Chitosan, Chorella sp., Flocculation

Ammonia (NH3) is one of the impurities in salt-producing water, which is often found in the traditional salt ponds of the Madurese. The purpose of this study was to determine the concentration of ammonia contamination as an impurity in salt production process water from raw water, reservoir ponds, evaporator ponds to geomembrane crystallizer ponds when salt production takes place in the salt ponds of Tanjungan Village, Bangkalan Regency. Determination of ammonia concentration using the phenate method based on SNI 06-6989.30-2005 with a spectrophotometer reading tool (UV-2700 Serial No. A11674900027) at a wavelength of 420 nm. The average concentration of ammonia as an impurity in raw materials in traditional pond ponds in Tajungan village, namely raw water is 2.31±0.24 mg/L, reservoir ponds are 2.56±0.57 mg/L, evaporator ponds are 2, 39±0.84 mg/L and the geomembrane crystallizer ponds are 1.37±0.09 mg/L. The highest average ammonia concentration was found in the reservoir ponds raw saltwater sample, while the lowest concentration was found in the geomembrane crystallizer ponds sample. The high average ammonia concentration in the salt ponds of Tajungan Village, Bangkalan Regency indicates that all raw saltwater in these ponds is contaminated with ammonia. The high concentration of ammonia in the salt ponds may be due to the entry of household waste. Keywords: (NH3), raw water, reservoir ponds, evaporation ponds, geomembrane crystallizer ponds

The need for feed determines 60-70% of aquaculture total production cost. Hence, the feed factor plays a very important role in performing an effective, efficient, inclusive, and sustainable aquaculture. The requirements needed to be a good cultivar are fulfilment of macronutrients and micronutrients, toxin-free, and accessible. Maggot can be used as a natural feed alternative in cultivation activities due to its sufficient nutrients content. Since 2012, aquaculture activities in Indonesia have increased alongside the rising needs for food and population growth. In this research, we conducted a research on the cultivation process of maggot by constructing three effective, efficient, and organized prototypes to achieve natural feed alternative for fish. In the first prototype, the hatching container (70x80x50 cm) will be designed with IoT censor for environmental parameter that is accessible in real time via the Blynk IoT platform. The second prototype is the vertical biopond, in which the structure and plastic container will be used to grow maggot. The structure of vertical biopond will be that of two-rack wood shelf with size specification of 80x100x34 cm. An important note to take, all designs will be created vertically. The third prototype is a 3 in 1 stall that has three components which are green net (200x150x100 cm), pupation container (30x42x15 cm), and hatching container (20x23x10 cm). All three designs can optimize the provision of economical and ecological feed that supports the fulfilment of Sustainable Development Goals in Indonesia.Keywords: Aquaculture, Black soldier fly, Internet, Natural feed, and SDGsÂ

The second prototype is the vertical biopond, in which the structure and plastic container will be used to grow maggot. The structure of vertical biopond will be that of two-rack wood shelf with size specification of 80x100x34 cm. An important note to take, all designs will be created vertically. The third prototype is a 3 in 1 stall that has three components which are green net (200x150x100 cm), pupation container (30x42x15 cm), and hatching container (20x23x10 cm). All three designs can optimize the provision of economical and ecological feed that supports the fulfilment of Sustainable Development Goals in Indonesia.Keywords: Aquaculture, Black soldier fly, Internet, Natural feed, and SDGs ","PeriodicalId":31102,"journal":{"name":"OmniAkuatika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46709350","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}

Pangandaran waters is one of productive fishing ground for Indonesian fisheries. One of potential catch in this area is red snapper. Red snapper (Lutjanus campechanus) is a type of demersal fish. This species can live in shallow waters to deep seas. Growth measurement is carried out as an anticipation on the presence of overfishing which causes red snapper stocks to decline. Hence, current field work focused on the growth characteristics and factor conditions of red snapper which landed in PPI Cikidang Pangandaran west Java. Present study may provide information related on fish species production. The survey and observation methods were used to collect the data in February 2021. The sampling location was carried out at the PPI Cikidang, Pangandaran. The data of weight and length of red snapper landed at PPI Cikidang were recorded and analyzed descriptively. The results revealed that growth of red snapper landed at the PPI Cikidang was categorized as negative allometric with b < 3, at 1.92. The condition factor has an average of 1.29 which means that the fish are classified as fat or not flat. Keywords: Growth Characteristics; Condition Factor; Red Snapper; Lutjanus campechanus; PPI Cikidang.
