Segara Anakan Lagoon is a unique and distinctive area where most of the ecosystem is dominated by mangrove ecosystems. Some fauna makes the ecosystem as a place for feeding ground, nursery ground and spawning ground for example macrozoobenthos. Its sessile nature makes the biota used as a bioindicator of an area. The Segara Anakan mangrove forest is currently under pressure due to the process of sedimentation and conversion of functions by residents. Therefore, this study aims to determine the interaction between the abundance of macrozoobenthos with environmental conditions. The research was carried out in July-September 2021 at the Segara Anakan Lagoon, Cilacap. The sampling method used is the Sample Survey Method with three stations determined purposively by describing different habitat conditions. Sampling was carried out on a monthly and the data obtained were analyzed by PCA. The results showed that the highest abundance of macrobenthos was found in the western part of the Segara Anakan mangrove forest. The value of macrozoobenthos abundance is influenced by TSS related to food availability. Furthermore, the quality of water and soil is still in accordance with the quality standards of marine life.Keywords: Environmental Characteristics; Macrozoobenthos; Mangrove; Segara Anakan

Microalgae are cultured as natural feed for the cultivation of mollusks, crustaceans (early larval stages), and zooplankton. Diatoms are phytoplankton groups commonly used as feed, one of which is Chaetoceros muelleri. This study aims to identify the optimal nitrate concentrations and light level (irradiance) for the growth rate of C. muelleri. Culture was placed in nitrate 1,330; 5,305; and 27,030 mg/L (N1, N2, N3, respectively); and light 50, 100, and 150 µmol/m2/s, with three replications for each treatment. The response variable observed was the growth rate of C. muelleri and nitrate uptake. Each nitrate treatment resulted in a significant difference in the growth rate of C. muelleri (LSD, p < 0.01). The N3 treatment produced the highest growth rate (average 0,188-0,193 cells/day), while N1 produced the lowest specific growth rate (average 0,149-0,157 /day). In light treatment, a significant difference was only seen in the light level of 150 µmol/m2/s (LSD, p < 0.05) which produced the highest growth rate (average 0.157-0.193 cells/day), especially in the nitrate N1 and N2. Meanwhile based on the significance test, the interaction between nitrate and light treatment was not significant.Keywords: Chaetoceros muelleri; Growth rate; Irradiance; Nitrate

Microalgae is one of the natural resources that has the potential to make biodiesel because it contains a fairly high amount of oil. The content of fat (lipid) and fatty acid (fatty acid) in microalgae is a source of energy and is used as raw material for biodiesel. In lipids there are elements of saturated fatty acids that play a role in the process of making biodiesel. The addition of growth nutrients into microalgae culture media is considered the most influential aspect on the quantity of biomass produced by microalgae cultivation. This study aims to determine the effect of chicken manure on the growth rate of Nannochloropsis sp. and to get the best treatment the lipid content of Nannochloropsis sp. of dry weight. The method used in this study was to use a non-factorial Complete RandomIzed Design (RAL) with 3 repeat treatments. The treatments in this study were A: 0 mg/L, B: 250 mg/L, C: 300 mg/L, D: 350 mgL.

This study aims to determine the relationship between length and weight and condition factors of Trichopodus trichopterus in the waters of Rawa, Lakea Dua Village, Buol Regency, Central Sulawesi. The research was carried out for 2 months and took place in the swamps of Lakea Dua Village, Buol Regency, Central Sulawesi. The fish collected were measured based on the total length using a ruler in cm (1 mm accuracy), while the fish weight was measured using a digital scale with units of grams (0.01 gram accuracy). The test parameters observed included analysis of length and weight, relative weight, fulcon condition factor, and relative condition factor. The results showed that there were 53 Trichopodus trichopterus collected in the swamps of Lakea Dua Village, Buol Regency. The length ranges from 10-18 cm with an average length of 14.43±2.39 cm. Fish weight ranged from 14.50-155.30 g with an average weight of 51.33±25.83 g. The growth pattern is negative allometric. The relative weight shows a value of 102.63±21.40, meaning that the source of feed is abundant in the Trichopodus pectoralis environment and the condition is healthy. The Fulcon condition factor value is 1.61±0.55 and the relative condition factor is 1.04±0.33, meaning that the condition factor value is below 3. This shows the cheek-shaped fish.

The purpose of this study was to determine the effectiveness of Spirulina platensis for remediation of vannamei shrimp culture waste. The method used in this study was a Non-Factoral Completely Randomized Design (CRD) with 4 treatments and 3 replications, namely (A) Control; (B) 50% waste (1500 ml waste + 1500 ml water) + technical fertilizer + Spirulina inoculant; (C) 75% waste (2,250 ml of waste + 750 ml of water) technical fertilizer + Spirulina inoculant; (D) 100% waste + technical fertilizer + Spirulina inoculant. Data analysis used ANOVA with 95% confidence level. The results showed that the use of Spirulina platensis as a remediation agent for vaname shrimp culture had a significant effect on reducing levels of waste ammonia, phosphate, nitrate, and density of Spirulina platensis (Fcount > Ftable 0.05).Keywords: Bioremediator; Innoculant; Vanname shrimp; Waste water
