Abstract

Gastropods are a class of the Phylum Mollusca, which use their stomachs as legs for walking. Gastropod habitat at this time, disturbances occur due to the many activities and changes in environmental physico-chemical factors are feared to cause a decrease in the number and abundance of gastropod species. This study aims to assess the abundance of Gastropods. The study was conducted from August to September 2020 in the Kuala Langsa Mangrove Ecosystem Area, West Langsa District, Langsa City. The research method used is a survey method with purposive sampling technique, consisting of 4 stations with 3 sampling times. Analysis of the abundance level was calculated using the formula for abundance and relative abundance. The results showed that the abundance of species of Gastropods amounted to 422.50 Ind/m2 and the relative abundance values ranged from 1% to 35%, indicating that the abundance levels were low and high.Keywords: Abundance,  Gastropods,  Mangrove Ecosystem, and Kuala Langsa

Abstract

AbstractThe Sumatran elephant is the largest land mammal that is threatened with extinction. Elephants are threatened for their survival due to habitat loss and human-elephant conflict. One of the mitigation efforts to reduce human-elephant conflict is to use the beehive fence method. Stingless bee was thought to influence elephant behavior. In this study, the behavior of the elephants that chosen was anti-predator behavior. The purpose of this study was to determine the effect of the stingless bee nest on elephant anti-predator behavior and to find out how the elephant's anti-predator response was. This study used field experiment method and for observing elephant behavior using a focal animal sampling technique. The data obtained were analyzed using the Kruskal Wallis test. The results showed that at treatment distances P1 (1 m) and P2 (1≤X5 m) the dominant response was elephant retreating away with a percentage of 67%. The conclusion of this study is that the stingless bee nest affects the behavior of the Sumatran elephant and the form of anti-predator response shown are flicking the trunk, produce sound and retreating away from the stingless bee nest.Keywords: stingless bee, behavior, anti-predator, Sumatran elephant AbstrakGajah Sumatera merupakan mamalia darat terbesar yang terancam punah.

Abstract

Violet Batissa (Batissa violacea) is an important economic organism on the west-south coast of Aceh, because it is relatively high consumed by the community. However, gold mining activities carried out around the watershed are estimated to pollute the river and cause B. violacea to also be affected. The purpose of this study was to determine the level of mercury (Hg) and Lead (Pb) contamination in clam meat in Teunom, Aceh Jaya Regency. The research was conducted from June to September 2021. Sampling of clam was done by purposive sampling method. Hg and Pb were analyzed in clam meat using the Atomic Absorption Spectrophotometer (AAS) method. The results of the analysis showed that the Hg content in clam meat was between 0.12-0.63 mg/kg (mean 0.35±0.26 mg/kg), water 0.0026-0.0103 mg/kg (mean 0.0052±0.004 mg/kg), and sediment 1.3224-3.8767 mg/kg (mean 2.2324±1.427 mg/kg). Furthermore, the results of the analysis showed that the Pb content in clam meat, water and sediment had the same value at 3 stations with values 0.0002±0 mg/kg, 0.0003±0 mg/kg, and 0.0002±0 mg/kg, respectively. The conclusion of this study is that the Hg content in water and sediment has exceeded the threshold, while the clam meat is still in good quality standards. The Pb content in clam meat, water and sediment were also in good quality standards. Based on our study, B. violacea is still safe for consumption, while the water has been polluted and is recommended not to be utilized for human consumption.Keywords:Heavy metalRiverWaterSedimentBatissa violacea

Abstract

Foam agents are crucial in the durability and performance of foam-based concrete. This study provides a critical finding related to foam agent characteristics, foam decay, the effects of foam modifiers (NaCl), and the properties of foam concrete, including shrinkage, compressive strength, and density. The foaming agent was prepared using sodium dodecyl sulfate (SDS) and triethanolamine (TEA) as a surface active agent, propylene glycol (PG) as a solvent, and NaCl as the foam modifier. The SDS:TEA:PG ratio was 1:1:2. The foam modifier was introduced in 0.1% to 0.8% varying concentrations to assess its impact on foam stability. The surface tension of the foam agent synthesis at a concentration of 20% was measured to be 0.1649 N/m, comparable to the commercial one. The decay rate foam of 0.095, 0.059, 0.063, and 0.013 cm/minute for the concentrations of 20%, 40%, 60%, and 80%, respectively. This suggests that higher concentrations of the foaming agent resulted in a more stable foam structure with slower decay rates. Moreover, the results showed that as the NaCl increased, the viscosity increased, but no effect on foam concentration of 80%. It was also observed that the combined effect of the foam agent concentration and NaCl concentration on viscosity was not linear. The recorded foam concrete shrinkage heights for the 20%, 40%, and commercial foam agent concentrations were 6.45 mm (SD 1.07 mm), 5.04 mm (SD 0.62 mm), and 4.0 mm (SD 0.94 mm), respectively. Furthermore, the compressive strengths of the foam concrete for the 20%, 40% foam agent concentration, and commercial foam were 4.41 MPa (SD 0,79 MPa), 4.20 MPa (SD 0.48 MPa), and 6.32 MPa, respectively. In conclusion, the foaming agent formulated from the mixture of components SDS, TEA, PG, dan NaCl has demonstrated the ability to produce foam concrete with satisfactory quality.
