Abstract

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. The results showed that the effect of giving chicken manure with different doses had a very real effect on the density of Nannochloropsis sp, and population peaks. Treatment B with a dose of 250 mg/L of showed the best results with an average density value of 4713 x 104 cells/ml and a population peak of 9415 x 104 cells/ml and the highest lipid levels found in treatment B, which is 12.73.  Water quality during the study was conditioned standard.

Abstract

Wolffia arrhiza has a growth rate and biomass as well as a good nutritional content for the growth of cultivated fish, especially herbivorous fish. Due to the high protein content (up to 45% of the dry weight), Wolffia is an excellent plant for the production of various biologically active substances, especially proteins. These plants can double every 1-6 days, similar to algae or mushrooms, and the number of leaves doubles every 2-3 days. This study aims to determine the effect of different fertilizer sources on doubling time, relative growth rate, population density and biomass of Wolffia arrhiza and water quality. The method used in this research is experimental. The research design used a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatments were as follows: treatment A: chicken manure, B: cow manure, C: buffalo manure and D: goat manure with each dose of 200 grams. Parameters observed included doubling time, relative growth rate, population density, biomass and water quality parameters. The results showed that treatment B (cow manure) gave the highest value for doubling time, 1.59 days, relative growth rate 0.392 g/day, population density 209.75 ind/cm2, biomass 94.97.

Abstract

The development of vannamei shrimp (Litopenaeus vannamei) cultivation still faces many problems. One of them is the availability of seeds whose growth is slow and variable, as well as high mortality after being stocked in ponds. This study aimed to examine the post-larval metabolic rate of tiger prawns in terms of oxygen consumption and ammonia excretion at different salinities. The research was carried out November - December 2023 in the Takalar Intensive Pond Unit, after which vannamei shrimp larvae with a density of 100 individuals/l were reared for acclimation for two weeks in tanks containing media water with a salinity of 10, 20 and 30 ppt. At the end of the acclimation period for the test shrimp, a respirometer was prepared to measure oxygen consumption and ammonia excretion. The results of the research showed that the average value of oxygen consumption after vannamei shrimp larvae occurred at a salinity of 10 ppt, then followed respectively at a salinity of 30 and 20 ppt. The results of the analysis of variance showed that salinity had a very significant effect (P<0.01) on oxygen consumption after vannamei shrimp larvae, but in the LSD follow-up test it appeared that only the 10 ppt treatment was very significantly different (P<0.01) and the same results occurred. on ammonia excretion, although the test of variance (LSD) had no significant effect. The survival rate and post-larval growth of vanamei shrimp reached the highest average value at a salinity of 20 ppt with very significantly different variance results. Based on the measurement results above, the optimum metabolic rate after vannamei shrimp larvae occurs at a salinity of 20 ppt (isotonic conditions occur between the shrimp's body fluids and the medium).Keywords: Ammonia Excretion; Metabolism Rate, Oxygen Consumption; Vanname Shrimp
