Abstract

Diseases can be caused by pathogenic microorganism that appears due to unhygienic attitude. Hygiene attitude have to be integral part of human life. The increasing of hygiene attitude can be reached by continuous education. The right knowledge that can forms and increases hygiene attitude is microbiology. The aim of this research is to know the correlation between knowledge of microbiology and Biology Education Students’ Hygiene Attitude. It was conducted at Jurusan Biologi FMIPA UNJ on April-May 2012. The method of this research that used is descriptive method with survey technique. The samples of this research are 50 Biology education studentsof class 2008. Samples were taken by simple random sampling technique. Prerequsite tests that used were normality test of Kolmogorov-Smirnov by SPSS 16.0 and Test of Homogenity of Variances (levene statistic) by SPSS 16.0. Statistic test which used was nonparametric technique by correlation test of Spearman Rank by SPSS 16.0. Result of the research shows that there is correlation between knowledge of microbiology and Biology Education Students’ Hygiene Attitude.

Abstract

This study aims to determine the effectiveness of biopesticides derived from pineapple peel extract (Ananas comosus) and sawdust biochar in controlling pests in eggplant (Solanum melongena). The research was conducted over 14 weeks at the Laboratorium Pengamatan Hama Penyakit dan Agens Hayati, UPT Pusat Pengembangan Benih dan Proteksi Tanaman, Cibubur, Jakarta Timur, using a factorial Completely Randomized Design (CRD) consisting of two factors: biopesticide concentration (0%, 25%, 50%, 75%) and biochar application (0 g and 500 g). Parameters observed included plant height, number of leaves, and the intensity of aphid (Aphis gossypii) infestation. The analysis results showed that the treatments of biopesticide, biochar, and their interaction did not significantly affect plant growth and pest resistance statistically. However, descriptively the combination of the two factors showed a positive trend on the vegetative growth of purple eggplant (Solanum melongena). These results indicate that organic waste such as pineapple peels and sawdust has potential as an environmentally friendly pest control agent.
