Abstract

There is a growing concern to use environmentally friendly pesticides including the use of plant-based pesticides. Given that bio pesticides are degraded easily, exploration and scanning to obtain new bio insecticides are continued to be practiced. One of the potential bio insecticides is bulian (Euderoxylon zwagerii). The bulian is a species of hardwood commonly used as construction material by the people of Jambi due to its resistance to termite and mold. The earlier research indicated that the sawdust of bulian is potential to treat Spodoptera litura F., an important crop pest. The purpose of this research is to develop active agents extracted from bulian sawdust to control pest crop especially C. Chalcites. The treatment include the application of bulian extract with concentration of 0,01%, 0,05%, 0,1%, 0,5%, and 1%. The smallest concentration of active extract with the strongest anti-feeding activity will be used as a reference for the following field studies of C. Chalcites. The results showed that, the higher the concentration of n-hexane extract is given, the higher the antifeedant activity of C. Chalcites. The smallest concentration that showed very strong anti-feeding of C. Chalcites is 0.5%

Abstract

The aim of this experiment was to study the effect of Carica papaya Linn seeds extract on pracopulation onthe reproductive function of swiss Webster female mice (Mus musculus L.). Parametric are: body weight, thenumber implantation, number live fetuses, number death fetuses and embryionic fetuses, post-implantationdeath, live fetuses were examined, libido and ovarium weight. The experiment was designed using thecomplete randomized design. The results tested using the DNMRT method. Treatment are control withoutCarboksil Metil Celulose (CMC) 1% (K0), control with CMC 1% (KCMC), Carica papaya ekstrac dosage 50, 75and 100 mg/kgbb (E50, E75 and E100). The results experiment showed that Carica papaya L. ekstrac candestroyed could disturbed the reproduction function, i.e disturbed accreation body weight for gestation, bodyweight mice 18 th day of gestation, decrease the number live fetuses, increase number death fetuses andpost-implantation death, there number embryonic resorption and body weight live fetuses treatment morelower concentrated control. But, no influence significant for number implantation and ovarium weight.

Abstract

Diversity, domination, and distribution of rice stem borer species and its damage in various land typologies in Jambi Province.  The research was conducted to analyze the diversity, domination, species distribution of rice stem borers (RSB) and its damage on various land typologies in Jambi Province.  The research was carried out using survey method, from December 2010 until June 2011.  Samples of RSB were collected from tidal swamp in Tanjung Jabung Timur District, swampy area in Muaro Jambi District, rainfed lowland in Sarolangun District, irrigated lowland in Merangin District, and irrigated upland in Kerinci District and Sungai Penuh District.  The results showed that there were five spesies of  RSB found in Jambi Province.  Scirpophaga  incertulas Walker (yellow stem borer) was the most dominant of RSB, followed by Sesamia inferens Walker (pink stem borer), Chilo suppressalis Walker (striped stem borer), Chilo polychrysus Meyrick (dark-headed stem borer), and Scirpophaga innotata Walker (white stem borer).  The distribution of S. incertulas, S. inferens, C. suppressalis and C. polychrysus were in all of rice field in Jambi Province, but that of S. innotata was limited over tidal swamp and  rainfield  lowland area. The RSB damage rate was lower than economic thereshold.

Abstract

The humans’ respiratory system is one of the material subject biology in eight grades of junior high school. Human respiratory system material requires an understanding of the concept. The use of interactive multimedia is one way to presenting the material. Based on the observation in SMP 24 Jambi found that the students are difficult to understand the material because the teacher is not optimal in using the media. Therefore, the teachers need a learning media to describe the material. Interactive multimedia flash can be used as the media. The purpose of this research is to develop and to know the students responses in the multimedia interactive learning material on the human respiratory system for junior high school in VIII class using Adobe Flash Professional Cs6. This research is the development research. The research design in this study follows the ADDIE development model.ADDIE development model has five stages: analysis, design, development, implementation and evaluation.
