Abstract

Nannochloropsis sp. is the green colored microalgae with its round shape of cell. This microalgae has lipids of 28,7% by dry weight, especially unsaturated fatty acids which can be transesterified to produce methyl ester and be a potential as biodiesel feedstock. The content of biodiesel Nannochloropsis sp. reaches 80% of dry weight and has the sama characteristics as vegetable oil. In the lipid extraction process many problems were found, one of which was the cell wall of Nannochloropsis sp. which prevents the lipid from being extracted. This research was carried out on 10 December 2022-28 February 2023 at the Hatchery and Aquaculture Technology Laboratory aquaculture study program, faculty of agrigulture, Malikussaleh University, Chemical Technology Laboratory at Lhokseumawe State Polytechnic and at The Environmental Quality Testing Engineering Laboratory At Syiah Kuala University, Banda Aceh. This study used a laboratory experimental method using a Non-Factorial Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications. Treatment A Control, treatment B Heating, treatment C Osmotic shock and treatment D Homogenizer. Based on statistical analysis of the F test (ANOVA) showed that the percentage of lipid from the application of pretreatment gave significantly different resulst to the percentage of lipid from the application of pretreatment. The highest lipid was found in treatment B which was 21,14% and the lowest lipid was in treatment C which was 12,51%. The highest lipid producer from the application of pretreatment is using the heating method. Biodiesel is obtained through a tranesterification process using methanol as a solvent and KOH catalyst.

Abstract

One of the reptiles whose natural habitat is in the sea and has the ability to migrate very far is the turtle. Threats that endanger the turtle population, both directly and indirectly, come from natural sources and from human activities. The factors that influence turtle nesting ground were predators, sand grain size, substrate humidity, substrate temperature, beach width, coastal vegetation and beach slope. Humans as one of the predators of the availability of turtles in nature by taking turtle eggs. The aim of the study was to determine the nesting habitat characteristics of the Lekang turtle (Lepidochelys Olivaceae) in the coastal area of Gampong Geulumpang, East Sulu, Dewantara District, North Aceh Regency. This research was carried out in November 2021, which took place on the coast of the village of Gelumpang, East Sulu, Dewantara District, North Aceh Regency. In this study, observational data collection and biophysical measurements were set at 3 stations. Station 1 (Dusun Cot U Sibak), station 2 (Dusun Pasie Kuala), and station 3 (Dusun Teupin). The distance between stations in this study was ± 2 km. Data analysis was carried out by weight body and scoring methods. Based on the results of data analysis from three observation stations at turtle nesting locations from several parameters such as beach slope is 4.5-9.3%, beach width is 10.20 -22 meters, the sand temperature is 29-32 0C, humidity is 21-28%, the size of the sand grains is 0.15322-0.31601 mm, while the coastal vegetation is 16.7-49.4%, it is concluded that the three observation stations are in the very suitable category for turtle nesting locations

Abstract

Microalgae is one of the microorganisms that has the potential as raw material in the development of research and technology to produce vegetable oil. Microalgae Spirulina sp. is a microalgae that has the potential to be used as a raw material for biodiesel, which has a fairly high lipid content when compared to other microalgae. However, to produce enough Spirulina sp. biomass, it is necessary to optimize the culture media.  One of the organic materials that can be used as Spirulina sp. culture media is vaname shrimp farming waste (Litopenaeus vannamei). This study aims to utilize vaname shrimp farming waste to minimize costs in mass-scale microalgae cultivation for daily lipid evaluation and biodiesel production. The method used in this study was laboratory experimental method, where observation and primary data collection were conducted on a mass scale. Based on the research results, the highest daily cultivation dry biomass of Spirulina sp. was found on day 4 (four) with a value of 2.29gr/L with a biomass percentage of 7.24%. The highest lipid extracted using soxhlet was on day 4 (four) with a lipid percentage value of 3.73% with a lipid percentage of 0.84% and the highest lipid productivity was also found on day 4 (four) with a value of 0.0854 gr/L. Mass cultivation biomass of Spirulina sp. obtained wet biomass of 13,760 g and dry biomass of 3,220 g. Lipid yield of Spirulina sp. in mass cultivation obtained a weight value of 163.74 g with a percentage of 5.09%. Biodiesel yield of Spirulina sp. in mass cultivation amounted to 101.225 g with a percentage of 61.82%. The quality of Spirulina sp. biodiesel consisted of 4 highest chemical compounds, namely Heptadecane (CAS) n-Heptadecane 41.35%, Hexadecanoid acid, methyl ester 13.03%, Isoppropyl Linoleate 8.91%, and 9,12-Octadecanoid acid (Z,Z)-, methyl ester 6.88%.

Abstract

Motile Aeromonas Septicemia (MAS) disease caused by Aeromonas hydrophila is a common pathogen that attacks freshwater fish commodities, including triploid as the new strain of striped catfish. This study aimed to test the resistance of triploid striped catfish to MAS infection before being released to farmers as a new commodity to increase national striped catfish production. The test was carried out for two months at the Sukamandi Fish Breeding Research Institute, Subang by injecting A. hydrophila into triploid and diploid striped catfish. The challenge test was carried out by injecting the cultured A. hydrophila with a density of 107 cfu.mL-1 as much as 0.1 mL.ind-1 at fish intramuscularly in all treatments, while in the Control (-) treatment, 0.1 mL of PBS solution was injected.tail-1. The test striped catfish used for each treatment were 10 individuals measuring 9.23 – 9.65 cm, and weighing 7.1 – 9.23 g. Survival parameter data and blood description were analyzed quantitatively using Microsoft Excel 2010 and SPSS version 16.0 software with analysis of variance (ANOVA) at a 95% confidence interval. The results of re-characterization with biochemical tests showed that A. hydrophila were gram-negative, oxidase and catalase positive, motile, could fermentatively convert sugar, and could grow in blood media. The survival of triploid striped catfish after the test was 95%, total erythrocytes on day 7, and total leukocytes on the first day were significantly different from diploid striped catfish. Thus, it can be concluded that striped triploid striped catfish are more resistant to infection with A. hydrophila than diploid.

Abstract

Priacanthus tayenus fish, often referred to as Swanggi, were found during fishing activities in the Cituis area, Banten. This indicates that the potential population of this fish remains substantial and has high economic value. A total of 30 fish were obtained, consisting of 11 female fish and 19 male fish. This study used the purposive sampling method. Analysis of the relationship between the length and weight of Swanggi fish from the waters of Cituis showed a correlation coefficient (r) of 0.9305. This figure indicates that the growth of the Swanggi fish is isometric. The length of the Swanggi fish (PB) increases with increasing morphological size. Food availability is thought to influence these correlation results. The availability of food plays a crucial role in the growth process. These correlation results indicate that food availability in the waters is still sufficient to support the life of the Swanggi fish.
