Abstract

Aedes aegypti mosquito is the main vector of dengue virus causing dengue hemorrhagic fever (DHF) in Indonesia. The main preventive action is to control the presence of Ae. aegypti mosquito. Banana plants are known to contain secondary metabolite compounds acting as a natural insecticide, including the hump part. This research was conducted to evaluate to toxicity of hump of Ambon banana extract (Musa acuminata L. cv. Gros Michel) to dengue vector Ae. aegypti mosquito. The research used experimental method, the treatment concentration was 0.001; 0.01; 0.1; 1; 10; 100 and 1000 ppm of Ambon banana methanol extract and 0 ppm concentration as a control, each with three replications. The variables observed were individual deaths at every stage of development and morphological damage. The data obtained were analyzed using the analysis of variety and Duncan test with 95% confidence level. In addition, probit analysis was used to determine the value of LC50. The results showed that the study of toxicity indicates that in the further stage of development, the toxicity of methanol extract from Ambon banana hump was less toxic. Toxicity of Ambon banana hump methanol extract was highest in egg with LC50 value of 314,852 ppm. The methanol extract of banana Ambon has the morphological destructive activity in all development stages of Ae. aegypti.

Abstract

This study aims to find out relations of college student habbit on the physical education in sport activity with his body mass index. Physical activity are usually done by everyone, as well as college student at physical education. It is familiar. This study was conducted at a time, in 36 students who were all male sex with the age range of 20-24 years old. To known the result from the data will be processed, researchers used an instrument of the questionnaire. The questionnaire was immediately filled by each respondent without given any treatment previously. Category was obtained from the measurement of body mass index between height and weight each respondent. There is only one group in this research, no groups were compared. The method used is quantitative and data analysis using the technique chi square.  The data obtained were then processed with SPSS 21 series. After data processed, the results show there is a significant correlation between both variables.

Abstract

Bemisia tabaci merupakan serangga vektor penyakit virus kuning tanaman cabai. Pengendalian dengan menggunakan insektisida sintetik berlebihan memiliki dampak yang negatif, sehingga dicari upaya alternatif dengan menggunakan insektisida nabati bersifat repellent. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak daun nilam, serai wangi dan kayu putih pada konsentrasi 40% terhadap repellency B. tabaci dan mengetahui ekstrak yang paling repellent terhadap B. tabaci. Penelitian dilakukan di Laboratorium Entomologi Balitsa, Lembang pada bulan April sampai Juni 2015, menggunakan Rancangan Acak Kelompok dengan empat perlakuan yaitu ekstrak nilam, kayu putih, serai wangi dan kontrol terdiri dari enam ulangan pada dua waktu pengamatan. Pengujian dilakukan menggunakan olfaktometer dua lengan. Pengamatan dilakukan pada jumlah B. tabaci dikedua lengan olfaktometer.  Data diolah menggunakan teknik ANAVA dan uji Duncan taraf nyata 5%, serta dihitung daya repellency untuk menentukan kelas repellency. Hasil penelitian menunjukkan bahwa ekstrak nilam, kayu putih dan serai wangi memiliki pengaruh terhadap repellency B. tabaci, dan ekstrak paling efektif bersifat repellent adalah ekstrak daun serai wangi dengan persentase repellency 48,33% dan 45,00%, serta daya repellency sebesar 100% terletak di kelas lima pada kedua waktu pengamatan.Kata Kunci : repellency, ekstrak nilam, ekstrak kayu putih, ekstrak serai wangi, Bemisia tabaci
