Metals are harmful pollutants because they cannot be broken down by living organisms. An excess of metal can become toxic. The metal in question is copper (Cu). This researchÂ aimedÂ to determine the phytoremediation effectiveness of Acorus calamus, Pistia stratiotes, and Azolla pinnata as candidates for Cu metal absorption. This investigation employed a wholly random factorial design with two factors: plant absorbent materials comprised of three plant species (Acorus calamus, Pistia stratiotes, and Azolla pinnata) and absorption concentrations of 2 and 5 ppm. The ANOVA test was used to analyze the data, followed by the average difference test. According to the results of this study, three plantsâ€”Acorus calamus, Pistia stratiotes, and Azolla pinnataâ€”are capable of reducing Cu metal in water. The Acorus calamus plant can reduce Cu concentrations in water from 2 ppm to 96.85% and from 5 ppm to 96.80%. Pistia stratiotes plants can reduce Cu level in water from 2 ppm to 96.50% and 5 ppm to 99.94% at concentrations of 2 and 5 ppm, respectively. The Azolla pinnata plant can reduce Cu level in water from 2 ppm to 98.50% and from 5 ppm to 96.54% at concentrations of 2 ppm and 5 ppm, respectively. The highest BCF value at a concentration of 2 ppm is in the roots of Azolla pinnata plants, at 6.77 mg/kg, followed by the leaves, at 8.88 mg/kg. The maximum BCF value at a concentration of 5 ppm for Pistia stratiotes plants is 2.26 mg/kg for the roots and 2.46 mg/kg for the foliage. The greatest concentration of TF at 2 ppm in Azolla pinnata is 1.31 mg/kg, while the maximum concentration at 5 ppm in Acorus calamus is 1.98 mg/kg

Shrimp waste is a perishable material. The degradation process is carried out by decaying microbes by producing degrading enzymes. The presence of chitin content in shrimp waste causes the emergence of chitinase enzyme-producing bacteria. Chitin is a linear homopolymer composed of N-acetyl-D-glucosamine monomers with -(1,4) glycosidic bonds. Chitin has unique properties, namely; biodegradable, biocompatible and non-toxic. This causes chitin and its derivatives to be widely used in various industrial and biomedical applications so that chitin and its derivatives have great economic value. There were 10 isolates of chitinolytic bacteria from shrimp waste with varying morphological characteristics. The ten bacterial isolates were NR02, NR03, NR04, NR05, NR06, NR07, NR08, NR09, NR10, NR11 and PU01. Chitinolytic index CI value > 2 was produced by 4 bacterial isolates, namely; NR02, NR07, NR09 and PU01. The lowest IK value was generated by NR08 with a value of 0.01. The chitinolytic bacteria obtained have different characters and it is very likely that they come from different types

Straw Mushroom (Volvariella volvaceae) as well asmushrooms edible otherhave been developed in Indonesia, including North Sumatra as a substitute for animal protein. Mushrooms or also known as button mushrooms are vegetables that are recognized to have high nutritional value, and are even believed to have medicinal properties for various types of diseases so that they have a fairly high selling value. Some studies report that in 100 grams of mushroom, only 0.17% fat is contained and even better, this fat is not bad fat. Seeing the high demand because of its nutritional value, and its rich content, its taste that is liked by many people, mushroom cultivation has a very promising market value. Basically until now the demand for mushroom continues to increase, but farmers have not been able to meet market needs. good quality start to be limited. Some farmers have started to switch to alternative planting media which is currently mostly practiced, namely oil palm pulp or empty palm oil bunches (TKKS). EFB is a waste that is very easy and is found mostly around palm oil processing factories, whose use has been limited so far as heating materials for boilers and particle wood, many empty bunches have not been utilized. This service aims to provide training in the form of mushroom cultivation using TKKS, as well as provide training in the form of post-harvest handling which is important given the lack of understanding of farmers in production and marketing activities.
