Abstract

Polyethylene terephathalate (PET) is a type of plastic content that is commonly is difficult to degrade so that it has an impact on global environmental problems. Plastic waste pollution needs to be overcome by using environmentally friendly methods to accelerate the PET plastic biodegradation process. Biodegradation is the use of microorganism activity to decompose plastic compounds so as to reduce the volume of waste. Ideonella sakaiensis is a bacterium that produces PETase enzymes that play a role in degrading PET. This literature review aims to determine the potential of Ideonella sakaiensis encoding the PETase gene in degrading polyethylene terephathalate plastic waste by discussing three focus studies, namely: 1) the potential of Ideonella sakaiensis, 2) the characteristics of polyethylene terephathalate plastic waste, 3) the relationship between the PETase coding gene and the degradation of polyethylene plastic waste terephathalate. Biodegradation of plastic waste Polyethylene terephathalate using Ideonella sakaiensis which has the potential to degrade PET faster with the PETase enzyme. The biodegradation mechanism carried out involves the process of transforming the PETase coding gene from I. sakaiensis to Escherichia coli bacteria influenced by pH and the effectiveness of the PETase enzyme work until the use of harvested products interacts with Polyethylene terephathalate plastic waste, which decomposes plastic waste.

Abstract

The leather tanning industry is one of the industries that causes environmental damage because one of the processes uses copper to produce products such as bags, jackets, and shoes. Copper bioremediation using indigenous bacteria is an effective solution to the problem of pollution because it utilizes bacteria isolated from the polluted environment. This study aims to isolate and characterize copper-resistant bacteria from the waste of the Yogyakarta Tannery Industry. The medium used was Luria Bertani Agar with the addition of 3 mM CuSO4. The characterization carried out included the characterization of colony and cell morphology such as color, edges, optical appearance, cell shape, and Gram staining. The isolation results obtained eight isolates of copper-resistant bacteria, namely Y1, Y2, Y3, Y4, Y5, Y6, Y7, and Y8. Isolates Y1, Y2, Y3, Y4, Y5, and Y8 were Gram positive bacteria while isolates Y5 and Y6 were Gram negative bacteria. Colonies of isolates Y1, Y3, Y4, Y8 greenish color indicates the accumulation of copper in the cells as a mechanism of resistance. The discovery of isolates of copper-resistant bacteria from samples of the tannery industry waste is a useful study as an initial study to obtain isolates of Indonesian indigenous copper-resistant bacteria to be further developed as a copper bioremediation agent in the treatment of copper waste in the leather tanning industry.

Abstract

Birgus latro or walnut crab is the largest land arthropod animal in the world, this crab has a unique and complex anatomy and body morphology that supports its survival. The research objective was to describe the anatomy, morphology, habitat, behavior, role, nutrition, reproductive system, immune system, gas exchange system, blood circulation, digestive system, excretory system, and Birgus latro osmoregulation. The research method used is literature review. This type of research is a form of qualitative descriptive research with review techniques from research journals on Birgus latro in Indonesia. This research was conducted by analyzing the results of research that had been published nationally and internationally relating to the life of Birgus latro. Walnut crabs live in areas that are damp and dark and avoid the sun to reduce the occurrence of evaporation on their bodies. Hard body parts such as shells, claws, and skin contain lots of calcium and chitin for self- defense and climbing coconut trees. The circulatory system of the walnut crab is open, this crab is also an osmoregulatory animal. The advice that the author can give for the preservation of walnut crabs is to provide outreach to the community regarding the importance of maintaining and preserving the existence of walnut crabs which are almost extinct. Establishing a walnut shell conservation center must also be carried out by the government to maintain the coconut crab population, as well as cultivate walnut crabs with the right procedure.

Abstract

The Rote turtle with the scientific name Chelodina mccordi is an endemic animal from Rote Island, East Nusa Tenggara. The Rote turtle is unique in its long neck and snake-like head. Rote turtles are rarely found in their natural habitat because many are hunted to be traded by collectors of endemic reptiles. The purpose of this study was to determine the effect of the habitat and behavior of the rote tortoise on its morphology and body mechanisms. The method used to compile this paper is to use literature reviews and literature studies from various sources to discuss 5 topics of study, namely: Rote Turtle Habitat, Rote Turtle Morphology, Blood Circulation System, Rote Turtle Respiratory System, Osmoregulation and Excretion of the Rote Turtle, and Uniqueness and Management of the Rote Turtle. Based on the results obtained, the habitat of the Rote turtle greatly influences the morphology and mechanisms of blood, respiration, osmoregulation, and excretion of the Rote turtle. The habitat for tortoise rote is the appropriate physical environment. Low rainfall of around 800-1200 mm/year and swamp grass with a height of about 2-3 meters. Potential predators for food and hunting have caused the Rote tortoise to become rare and rarely found in its natural habitat. The NTT government has designated three natural habitat lakes are natural habitats and the Governor of NTT Decree Number: 204/KEP/HK/2019 made the rote turtle habitat for the rote turtle Essential Ecosystem Area.
