Abstract

All sea turtles are listed as endangered and critically endangered by IUCN Red List due to human consumption and lifestyle. In West Sumatra, Pasir Jambak Beach is an important habitat for nesting of sea turtles, but human activities in this area becomes serious threats for sea turtles. Based on our interview, the local people of Pasir Jambak still consume the sea turtle eggs and mistaken for the effect of this egg to human. During our activity, we share our knowledge especially to the children of Pasir Jambak, hoping that they will not continue the habit of consuming the sea turtle egg, and become more concerned to the conservation of sea turtle around them. All of us were responsible for the rapid decline of sea turtle populations. We also take an action for cleaning the Pasir Jambak beach from the plastic trash and released the Tukik (juvenile) to help increasing the sea turtle population in nature.

Abstract

Fluorescent pseudomonads are a group of bacteria derived from the rhizosphere of plants. Fluorescent pseudomonads have potential as plant growth promoters capable of producing Indole Acetic Acid (IAA). This study aims to obtain fluorescent pseudomonad isolates that can produce IAA. The fluorescent pseudomonad isolates used were isolate Pf31 (derived from the rhizosphere of the longan plant), Pf32 (derived from the rhizosphere of the cassava plant), Pf33 (derived from the rhizosphere of the guava plant), Pf35 (derived from the rhizosphere of the galangal plant), Pf36 (derived from the rhizosphere of the guava plant). red ginger), Pf37 (derived from the rhizosphere of the Alocasia plant), Pf38 (derived from the rhizosphere of the celery plant), Pf39 (derived from the rhizosphere of the turmeric plant), and Pf40 (derived from the rhizosphere of the Oxalis plant). namely the detection of the ability of fluorescent pseudomonads to produce IAA. The results obtained showed that the fluorescent pseudomonads isolates Pf31, Pf32, Pf33, Pf35, Pf36, Pf37, Pf38, Pf39, and Pf40 had the ability to produce IAA with the highest concentration produced by isolate Pf36 which was 9.86 ppm and the lowest concentration was produced by isolate Pf38. ie 3.65 ppm.
