Abstract

The lithology of Jolosutro Beach, Blitar Regency, East Java was studied using remote sensing methods. The purpose of this study was to identify the lithology of rocks at Jolosutro Beach, Blitar Regency, East Java. Satellite images are Landsat 8 OLI/TIRS satellite images. The Landsat 8 OLI/TIRS satellite images were then adjusted and combined with RGB. The results of remote sensing data processing showed that the surface lithology of the study area was dominated by andesite-basalt-wash rocks, whose origin is suspected to be from Futhokria and Tenggeri mountains.

Abstract

The control of the Aedes albopictus mosquito vector still relies on the use of insecticides. The use of insecticides if not appropriate can have a negative impact on the environment and non-target organisms. Neoregelia spectabilis is a plant from the Bromeliaceae family which is often used as a natural breeding site for Aedes albopictus. In addition to the morphological factors, it is suspected that there are interesting chemical compounds that make this species a breeding site for Aedes albopictus mosquitoes. This study aimed to analyze the content of chemical compounds that are attractants from the plant species Neoregelia spectabilis. The research method began with taking samples of young leaves, extracting them by maceration, concentrating with a rotary vacuum evaporator and testing the content of compounds using the GCMS Variant Sarurn 2000. The results of the GCMS analysis showed that the chemical compounds present in Neoregelia spectabilis are compounds from the groups of alcohols, alkanes, esters, and terpenes One of the attractant compounds found is a compound from the alkane group. The group of alkane compounds was found as much as 50.63%.

Abstract

The Aedes albopictus mosquito is one of the main vectors that causes Dengue Hemorrhagic Fever (DHF) which needs to be controlled. Control using natural insecticides derived from plants is proven to be safer. The purpose of this study was to determine the effect of coconut, banana, bamboo and bromeliad leaf extracts on the number and hatchability of Aedes albopictus mosquito eggs. This type of research is an experiment with a Completely Randomized Design (CRD) pattern which was carried out in the Billfath University laboratory. The treatment consisted of extracts of banana leaves (10% DP), coconut leaves (10% DK), bamboo leaves (10% DBa), bromeliad leaves (10% DBr), control (100% water). The results showed that coconut, banana, bamboo and bromeliad leaf extracts had an effect on the number of Aedes albopictus eggs but had no effect on the hatchability of Aedes alboictus eggs, with the highest average number of eggs in the 10% bromeliad treatment of 5.42 eggs.
