Abstract

Intensive vannamei shrimp cultivation is a high-density culture to get maximum results with the use of limited cultivation space. High cultivation activities cause high waste production, which inhibits growth, survival rate, and feed conversion ratio (FCR). This study aims to determine the cultivation of vannamei shrimp with an intensive system on growth, survival rate, and FCR. The research was carried out in Legok Jawa, Pangandaran in the period March–May 2022. The research was carried out by means of a survey and analyzed by a quantitative descriptive approach. The results of the study obtained growth values, namely: Mean Body Weight (MBW) ranges from 1.61 to 21.11 g/head, Average Daily Growth (ADG) ranges from 0.14 to 0.62 g/day, size is 49 fish/kg and biomass is 7,680 kg. The survival rate value obtained is around 95.07 – 84.87%, while the feed conversion ratio (FCR) value ranges from 1.2 to 1.5. In general, the results of growth, survival rate, and FCR showed high performance and supported the success of vannamei shrimp culture with intensive systems.

Abstract

Eichornia crassipes have root fibers that can repair water quality, improve the concentration of chlorophyll-a, increase growth, and maintain the survival of local catfish. The purpose of this study was to obtain the best biomass of water hyacinth for the increasing concentration of chlorophyll-a on local catfish rearing in August – September 2020. This study used a one-factor completely randomized design (CRD) with 4 treatments and 3 replication. The treatments in this study had different water hyacinth biomass, P0 (Control), P1 (112 g m-2), P2 (162 g m-2), and P3 (212 g m-2). The local catfish seeds that are used are sized approximately 5-7 cm, weigh 2.62-3.02 g, maintained for 30 days in a rearing container with a peat water volume of 98 L and a density of 2 fish L-1. The result showed that the best treatment was biomass 212 g m2 water hyacinth containing concentration chlorophyll-a 0.73 µg L-1 with the value of correlation concentration chlorophyll-a (r)=0.97 and R2=0.95, it was able to improve concentration chlorophyll-a on local catfish rearing such as increasing pH 5.7-6.0, nitrate 2.45 mg L-1, phosphate 2.09 mg L-1, temperature 27-280C and dissolved oxygen 5.4-5.5 mg L-1. Absolute weight growth (9.04g) with the value of correlation (r) = 0.99 and R2 = 0.99, and survival rate of local catfish (94.67%). The highest growth of the biomass water hyacinth per 3 days is 2.82%.

Abstract

Anchovies (Stolephorus sp) are fish that have important economic value even though they are small. This fish is rich in nutritional content and has a savory and delicious taste when processed into food. This fish is very liked by various groups even though it has a small size and without bones. This anchovy contains lots of calcium, protein and minerals such as phosphorus and iron that are very useful for increasing the intelligence of children and toddlers, as well as for preventing osteoporosis in pregnant women and the elderly as well as helping in the growth of bones and teeth in infants, toddlers and children. To improve the quality of anchovy nuggets, it is necessary to add certain binders to improve the taste of anchovy nuggets. This study aims to improve the quality of anchovy nuggets by adding a binder in the form of servedku flour and adding to the economic value of refined anchovy so that it is more attractive to the public. There were 3 treatments and 2 repetitions. The treatments were A. Anchovies; A1 = using carrots, A2 = without carrots and treatment B (sajiku flour concentration); B1=100g, B2= 200g. Moreover, Treatment C (cooking temperature); C = 65ºC - 85ºC for 30 minutes. From the results of the study, it can be seen that the water content, protein content and fat content did not show any significant effect.

This research was conducted for five months from May to September 2022 which is located in Sungai Apit District by taking six (6) villages as sampling locations from eight (8) existing villages. The research objective was to calculate and assess the adaptive capacity of mangrove ecosystems in Siak District, Siak Regency. Measurement of the adaptive capacity of mangrove ecosystems is carried out by analyzing six parameters, namely Mangrove Dimension Index (IDMg), Dominant Mangrove Species, Mangrove Tree Density, Number of Mangrove Species, Substrate Type, Ecosystem Distance from Settlement. The value of the adaptive capacity of mangrove ecosystems is in the range of 0.0-1.0, with five capacity categories namely "very low, low, medium, high, and very high". The results showed that the number of mangrove species found growing on the coast of Sungai Apit District was 19 species belonging to 10 families and 12 genera, distributed in the "low" category with a mangrove dimension index (IDMg) value of 0.6 (0.4<IDMg <0.8).Dominant species from the Rhizophoraceae family with a density classified as "high". The adaptive capacity of the mangrove ecosystem at the study site is classified as "high" with an adaptive capacity value of 0.67 (0.6 ≤ KPMg ≤ 0.8).
