Abstract

Research on the toxicity of n-hexane extract of Albizia falcataria sawdust against Hypothenemus hampei has been conducted. The method of research was contact method. The concentrations used in the experiment were control (aquadest); 0.25%; 0.5%; 1%; 2%; and 4%. Every concentration was sprayed on the female imago. Observations were performed 120 hours after treatment. The results showed that there was an effect of the length of observation time and concentration on the mortality of H. hampei (GLM Test α= 5%). The time of observation and concentration of A. falcataria sawdust n-hexane extract has positive correlation on H. hampei mortality. Therefore, the longer the treatment time, the more H. hampei mortality is increased. The mortality of H. hampei also increased with increasing concentration given. At a concentration of 4%, extract of A. falcataria sawdust has high toxicity which causes the highest mortality (> 92%).

Abstract

This study aims to determine the resistance status of Ae. aegypti to the deltametrin insecticide in Sumbersari Jember Village. A total of 100 2nd generation female Ae. aegypti were tested using the CDC bottle bioassay with a deltamethrin dose of 10 μg/ml and a diagnostic time of 30 minutes. Molecular detection using AS-PCR was also performed to detect kdr mutations at position 1016 of the VGSC gene. Mortality data was calculated using Ms.Excel with a confidence level of 95%. The molecular wight of the PCR product is calculated using a gel analyzer application.  The results of the CDC bottle bioassay show that the Ae aegypti population is still tolerant to the insecticide deltamethrin (91,25% in mortality rate). However, molecular analysis confirms the presence of a mutation at position 1016 of the voltage-gated sodium channel (VGSC) gene (homozygous mutation), which is known to be the primary target of pyrethroid insecticides. These findings indicate that although phenotypic resistance has not yet fully developed, the mosquito population has shown early indications of target-site insensitivity to deltamethrin, which has the potential to develop into resistance under sustained selection pressure. Further use of deltamethrin insecticide may potentially increase phenotypic resistance, namely a decrease in mosquito mortality after exposure to deltamethrin insecticide. Therefore, an integrated vector control strategy and routine monitoring of mosquito resistance status in the region are required.

Abstract

Pancer Coastal is one of the southern sea beaches located in Puger Kulon Village, Jember. The characteristics of the beach and the sloping geographical allow Puger Kulon Village to develop into a beach-based tourism village.  The southern sea has a harsh choppy character with sandy beaches so it needs plant vegetation that acts as a barrier. The need for vegetation as a barrier in the second zone besides the sea pandan which already exists as the first barrier initiated the planting of shrimp cypress in the Pancer coastal area. Planting shrimp cypress is beneficial in resisting wind speed and keeping air conditions cooler in addition to being able to reduce the impact of tsunamis and abrasion in coastal areas.  Shrimp cypress can live in extreme conditions, resistant to drought and strong gusts of wind and pest attacks. This activity aims to revitalize the pancer beach area in order to support sustainable ecotourism. This activity is carried out through observation, coordination with related parties, provision and planting of shrimp cypress seedlings, shrimp cypress maintenance and provision of coastal environmental management modules. A total of 200 shrimp cypress seedlings have been planted on Pancer coastal involving the assisted village service team in collaboration with the village government, Pokdarwis and marine members from the Pam Puter XXVIII Nusa Barong Island Ops Task Force.
