Abstract

This study aimed to determine the effectiveness of aquatic plant phytoremediation in reducing ammonia levels in catfish (Clarias sp.) cultivation water. This study used a non-factorial Randomized Block Design (RBD) with 5 treatments and 3 replications (n = 15 experimental units), consisting of a control without aquatic plants (P0) and four aquatic plant species, namely water lettuce (Pistia stratiotes L.) (P1), water hyacinth (Eichhornia crassipes L.) (P2), duckweed (Lemna sp.) (P3),  and  water  spinach  (Ipomoea aquatica L.)  (P4), each placed at 25% of the circumference of a 14-liter container for 28 days of observation. \Water quality parameters including ammonia, DO, BOD, and COD were measured using a UV-Visible spectrophotometer at the laboratory and pH was measured using a pH meter in the field on days 0, 14, and 28. Data were analyzed using One Way ANOVA and Duncan's Multiple Range Test (DMRT) post-hoc test at a significance level of ≤ 5%. The results showed that all aquatic plant species effectively reduced ammonia levels, where Eichhornia crassipes (water hyacinth) produced the highest reduction of up to 79% and a 10% decrease in pH levels compared to the untreated control, while Lemna sp. (duckweed) reduced DO levels by up to 25%, BOD levels by 1.21%, and COD levels by 1.28% in the catfish cultivation water. This study concludes that phytoremediation using aquatic plants, particularly water hyacinth, is proven to be the most effective natural alternative for reducing ammonia levels in catfish cultivation water and has potential for application in sustainable aquaculture systems.   Keywords: Ammonia, Phytoremediation, Aquatic Plants

Abstract

This study aims to assess the diversity index, relative abundance, and evenness of soil insects in the Hutan Desa Serdang, Tahura Area, Karo District, North Sumatra. The methods used include pitfall traps and bait traps with a purposive sampling approach at three observation stations: primary forest, secondary forest, and pine forest. The results show that a total of 1,427 insect individuals were found, comprising 8 orders, 13 families, and 20 species. Odontomachus brunneus exhibited high relative abundance, followed by Entomobrya handschini and Solenopsis invicta, which fall into the category of moderate relative abundance. The diversity index of soil insects is categorized as moderate, with an value of H' = 2.0, indicating a balanced ecosystem with a sufficient variety of species. Meanwhile, the evenness index of soil insects is classified as high, with a value of H'= 0.7. This indicates a uniform distribution of species without particular dominance, thus supporting ecological balance and good soil ecosystem quality.

Abstract

Periphyton is one of the biotic components, living attached to various substrates has an important role in providing primary productivity of waters. The purpose of this study was to determine the identification of species, the structure of the periphyton community in natural and artificial substrates, the water quality of the Namu Sira-sira River in Langkat Regency. The data collection method was carried out using the "Purposive Random Sampling" method at three stations according to community activities in the research area.The results of the study obtained species found in natural substrates were 25 species and artificial substrates were 27 species. The community structure including the diversity index (H ') is included in the medium category with a value of 2.48 on natural substrates and artificial substrates with a value of 2.50. The uniformity index value (E) on natural substrates is 0.89 and artificial substrates are 0.90 categorized as high because the distribution of species in each station is even. Periphyton communities on natural substrates have advantages in terms of abundance and diversity compared to artificial substrates due to the complex interactions between environmental factors, substrate quality, and ecological processes that support their growth
