The aims of this reserach were to isolating and to identifying bacteria entomopathogenic on caterpillar pests in cabbage. The study was conducted in three phases. The first stage isolation of bacteria from cabbage caterpillar pests, the second stage of microscopic characterization of bacterial isolates and the third phase molecular identification of bacteria isolates using 16S RNA gene. The results were obtained five bacterial isolates of caterpillar pests in cabbage which 4 isolates shaped cocus, three isolates of gram positive and gram negative two isolates. All of isolates were able to degrade D-glucose. Isolates were translucent white color, white yellowish and brownish white. Generally isolates are not motile dan growth in the media to the surface. Results of DNA extraction and amplification of 16S RNA gene, showing the purity and concentration of DNA is good, confirmed by electrophoresis, amplicons formed band at 1500 bp according to the characteristics of the 16 S RNA gene

Aedes mosquitoes have the behavior of sucking blood repeatedly (multiple bites) in one gonotrophic cycle, these mosquitoes are also very effective at transmitting the virus to humans (WHO 2004). Kawada et al. (2007) reported that the foraging activity of A. albopictus was less than 0.1 times compared to A. aegypti under laboratory conditions, this result is consistent with the tendency to bite both species in nature. The target-attack frequency (foraging activity) in A. aegypti female mosquitoes in unfed conditions is 30 times greater than that of A. albopictus mosquitoes in several laboratory treatments (Kawada, et al. 2007). Aedes sp is a deadly infectious vector between another dengue hemorrhagic fever (DHF) and chikungunya. Pineleng is a marginal/suburban area of Station 1. Recent studies have reported changes in habitat patterns of Aedes sp, especially Aedes albopictus and Aedes aegypti . The aim of this study is to characterize the population density of the Aagoan sp. Imago based on the time distribution and altitude of the sea surface. The population density characteristics of the Aedes spagoed imago captured inside and outside the room based on the time distribution in North Sulawesi. The stages of the study consisted of larvae surveying, larval extraction and analysis, and imago extraction and analysis. The results showed that the high population of Ae aegypti was at 8:00 a.m. to 10:00 p.m. in the morning and 14:00 to 16:00 p.m. in the afternoon before the afternoon. in the morning before noon and at 14:00 to 18:00 in the afternoon before evening.

Inquiry-based learning refers to a sequence of educational activities that aim to fully engage students in methodical, critical, logical, and analytical processes of searching and investigating. The ultimate goal is for students to independently develop their own discoveries with a high level of confidence. This study aims to find out the students' mastery learning results by using the inquiry learning model in which the material is related to the structure and function of plant parts. This research is classroom action research. This research was conducted at SMP Negeri 6 Tondano. The research subjects were class VIII students, totaling 27 people. The results showed that the percentage of learning completeness in cycle I was 29.63% with an average score of 60.62, and cycle II was 92.60% with an average score of 81.07. The results of this study indicate that learning the structure and function of plant parts using the inquiry learning model can improve student learning outcomes.

Biology learning demands learning competencies in the realm of high-level understanding, so many students find it challenging to develop their critical thinking skills and, therefore, have difficulty completing various concepts in biology. For this reason, a particular way of learning is needed so that it fosters students' critical thinking skills through creative and collaborative thinking skills so that they can be well-honed in order to be able to solve various complex concepts in biology. Therefore, this research aims to determine the creative and collaborative thinking abilities of class X SMA Negeri 1 Airmadidi students on Animalia material, focusing on their creative and collaborative thinking abilities. This type of qualitative research describes data obtained from a rubric containing research indicators. The research results show that the profile of students' creative and collaborative skills shows good development based on the indicators obtained. Indicators of creative and collaborative thinking abilities are at scores 3 and 4, which shows that students can give excellent and precise answers to both questions through discussions and written tests. Based on these results, the analysis of creative and collaborative thinking abilities in class X12 students at SMA Negeri 1 Airmadidi is in good ability results.
