Abstract

ABSTRACT There is no teacher makes character modules on subjects of biology. The use of a limited number of books and supporting students who came from the printing module used student does not meet the actual module components. There are also weaknesses in the present picture of them colorless, the concepts of the material in less clear learning objectives, in addition to supporting books and modules that are used do not seem character values. As a result students difficulty doing exercises or questions that the teacher and students are not stimulated to develop character values both at school and in public life. To the researchers have developed teaching materials in the form of character modules. This research aims to produce valid character module practical matter respiratory system. This type of research is the development of research (research and development) with 4-D models that define (definition) consists of the analysis of the curriculum, desaign (design) module and enter the value of character, develop (development) and dessiminate (spread). This research has been carried out and campus STKIP PGRI and SMAN 6 Padang, from the month of March-April 2013. At this stage of develop test the validity (2 teachers and 2 professors) and the practicalities by two biology teachers and students of class XI IPA4  many as 33 people. Character module on material generated respiratory system is very valid criteria for high school and very practical, with an average of 87.08 % validation (very valid) and the average value of the practicalities of 93.58 % (very practical). Expected products resulting from the research is the development of character modules can be used by teachers in the learning process, especially in SMA N 6 Padang, the teacher should remind students to practice honesty in filling out worksheets and do not see the answer key sheet module before work is      completed.

Abstract

Chili is a herbaceous plant of the family eggplant (Solanaceae) which has the scientificname Capsicum annuum L. Chili has a lot of nutrients and vitamins, such as calories, protein, fat,carbohydrates, calcium, Vitamin A, Vitamin B1 and Vitamin C. Besides being used for domesticpurposes, peppers can also be used for industrial purposes such as, industry-seasoning, food andmedicine or herbal. Efforts to increase the production of chili still have problems due to pestaphids (Myzus persicae). Aphids reproduce in two ways: with and without marriage or their eggscan develop into young without fertilization (Partegonesis). This pests life cycle ranges from 7-10 days. These pests attack plants by sucking liquid chili leaves, shoots, flower stalks or otherplant parts, so that the leaves become mottled yellow (chlorotic) and eventually fall so chiliproduction declined. This insect will be clustered so as to cover part of the plant. Of control thispest than by using insecticides as well as biological control by predators. Predator beetles arefound is the javelin (Menochillus sexmaculata). Has done research on leaf Mite PopulationDensity (Myzus persicae) and the predatory beetle javelin (Menochillus sexmaculata) At Chilliplants. This study was conducted using a descriptive survey in April 2012, from the results, thepopulation density of aphids Myzus persicae with an average of 64.4 people per stick plantpredatory beetles and javelin Menochillus sexmaculata with an average of 2.4 individuals perstick plant.
