Abstract

Aedes aegypti is the main vector that transmits dengue fever. The spread of Aedes aegypti mosquitos in Indonesia is very wide. This mosquito has its breeding site in clear water areas such as in the bath water containers, flower pots, pet containers as well as in the used goods that can hold stagnant water. However, the environmental conditions which are constantly changing due to the rampant pollution cause Ae. Aegypti to continue to adapt to its breeding environment. This research aims to find out the egg laying behavior, life cycle and mediums preferences selected by Aedes aegypti mosquitos in different water mediums. Stages of the research which are conducted include: preparation of research tools and materials, observation on Ae. Aegypti mosquitos’ preferences, observation on egg hatchability and life cycle of Ae. Aegypti in various water mediums. The result shows that from all contaminated water mediums which are tested, Ae. Aegypti mosquitos have the preference of laying eggs in Eichhornia crassipes water mediums, followed by leachate water mediums, whereas in tofu wastewater mediums and laundry waste, there were no eggs found. Meanwhile, in another study, it is known that the egg hatchability and life cycle of Ae. Aegypti mosquitos in contaminated water mediums such Eichhornia crassipes immersed water mediums, and leachate water are not significantly different from controlled water mediums (uncontaminated). The result of the research is expected to be the reference for relevant institute in expanding the eradication of Ae. Aegypti mosquitos to places that have been unusual for eradication.Keywords: Aedes aegypti, Eichhornia crassipes immersed water, Leachate, laundry waste, tofu wastewater

Abstract

The City Park is conceived as a space that contains the elements of nature and landscape which is caused by vegetation diversity, activity and artificial elements that are provided as a social and recreational facilities, as well as a breathing space in the city. The Semarang State Park is one of the green open area that are also used by birds. On the other hand the city park has a problem that threatens the existence of birds especially the uncontrolled development. The diversity of the species of birds can be used as indicators of environmental quality, because their life is influenced by the physical, chemical, and biological cchanges in the environment. The research objective was to determine the diversity and abundance of the bird species, determine the composition of the guild of bird species, and to determine the status of the scarcity of birds in the city garden of Semarang. The research was conducted in July-August 2016, where observation was carried out in six state parks in Semarang using the point count method. The analysis of the index used are the abundance of species, species diversity index, evenness index, similarity index, chi square test and hucthinson method.Where795 individuals of birds were observed, covering 27 species and 17 families. The diversity of bird species index categorized moderately were 2.19 to 2.33, except on Park Madukoro which had the lowest category. The birds were categorized evenly with the index 0.74-0.83, except in the Madukoro Wildlife where the categories were fairly even. The composition of the most abundant guild is a group of insectivorous which is 41%. There are 27 species of birds in all six State Parks in Semarang which however have the status of Least Concern by the IUCN. Based on Government Regulation No. 7 of 1999, there are four species of birds included into the category which are protected.Keywords:  State Parks, bird, diversity, abundance, composition guild

Abstract

The countermeasures of DHF disease is caused by several factors which is interacted one another. Application of insecticide as larvacide is the most common way to used by society to control vector growth and insecticides are often used in Indonesia is Abate with temephos active ingredient. This research aimed to asses the effect of application larvacide with active ingredient temephos to mortality of Aedes aegypti pupae stadium and survivality imago stadium. The type of this research was an experimental research using post only control group design approach. The population used in this research was Ae. aegypti pupae which was breed in the laboratory. The number of tested pupae used in this research were 25 for every tested medium and conducted for 5 times repeatedly. Therefore, the total of pupa used were 750 larva. The data analysis using the Kruskal wallistest and followed by Mann whitney test.The analysis result showed that there were significant differences between the number of pupae which become imago (p=0.001) and the number of imago which survived until the second week (p=0.001). Death occurs because temephos belongs to organophosphate compounds that have anticholinesterase action.Inhibits cholinesterase enzyme, causing disruption to nerve activity because acetylcholine accumulates on the nerve endings an causes death.
