Abstract

Chili is a herbaceous plant of the family eggplant Solanaceae) which has the scientific name 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 domestic purposes, peppers can also be used for industrial purposes such as, industry-seasoning, food and medicine or herbal. Efforts to increase the production of chili still have problems due to pest aphids (Myzus persicae). Aphids reproduce in two ways: with and without marriage or their eggs can 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 other plant parts, so that the leaves become mottled yellow (chlorotic) and eventually fall so chili production declined. This insect will be clustered so as to cover part of the plant. Of control this pest than by using insecticides as well as biological control by predators. Predator beetles are found is the javelin (Menochillus sexmaculata). Has done research on leaf Mite Population Density (Myzus persicae) and the predatory beetle javelin (Menochillus sexmaculata) At Chilli plants. 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 plant predatory beetles and javelin Menochillus sexmaculata with an average of 2.4 individuals per stick plant.

Abstract

ABSTRACT Instructional media can be defined as the means for facilitating the teaching and learning activities. They can be facilities which provides the students with visual experience to motivate them to learn, explain and simplify the abstract complicated concepts into simpler, more concrete  and more understandable ones. They generate the students’ curiosity, motivate and stimulate them to learn. The media used previously, however, had made the students got bored so that they were not interested in paying attention to the teachers explaining the lesson in front of the class. To deal with this problem, comic instructional media for teaching human neural system which  was  intended  to  motivate the  students  to  learn  and  to  improve  their  learning  interest  was developed. This research was aimed at revealing the validity and the practicality of the instructional media. This was a developmental research which used 4-D models that consisted of four developmental stages including defining, designing, developing and disseminating. For the limitation of time and budget, in this research, however, disseminating phase was excluded. The media developed were validated by t wo lecturers and two teachers of SMP Pertiwi Siteba Padang. The practicality of the media was seen from the responses given by two teachers and 25 students in class IX-1 of Junior High School. The result of data analysis indicated that the comic media developed was valid in which the validity value was 78,33%. The validity was viewed from didactic, construction and technical variables. The result of the practicality test from the teachers showed that the comic media was practical in which the practicality value was 78,55%, while the result of the practicality test from the students indicated that the comic media was very practical in which the practicality value was 88,05%. The practicality was viewed from the students’ interests, the pictures displayed in t he media, the process of using the media, material and conceptual understanding, time efficiency and evaluation. Based on these results, it was concluded that the comic instructional media developed for teaching human neural system had been valid and practical.

Abstract

ABSTRACBivalve is one of fisheries products having essential value as a source of food.  It is caught in a variety of type sand sizes. Polymesoda bengalensis is a regarded as filtration feeders and detritus feeders. Filtration feeders refine plankton from the waters around, while the Detritus feeders make use of organic materials from plants falling down to the bottom of the water. This research was   designed for revealing the natural forage given to the cultivation of Polymesoda bengalensis. This cresearch was conduced in January 2013 to analyze Polymesoda bengalensis bowel in Muara Nipah Kecamatan Sutera Kabupaten Pesisir Selatan. To conduct the research, survey Descriptive method was applied. The sample was was chosen by using Random Sampling method. The numbers of the sample analyzed was 30 in which the length of the bivalves bodies were < 30 mm, 30-50 mm, and > 50 mm. There were 10 bivalves taken as the representation of each size.Based on the result of data analysis, Detritus and 12 genus of Phytoplankton were found in the Polymesoda bengalensis bowel. Detritus was the most dominant natural forage found in the bivalves bowel. The frequency of its existence was 100%.   In the bowel of bivalves of <30 mm length, Detritus was the most dominant food found (49,465) followed by Synedra (8,6%). In the bowel of bivalves of 30-50 mm length, the food found was dominated by Detritus (47,77%) followed by Synedra (10%), while in the bowel of bivalves of > 50 mm length, the food found was dominated by Detritus (39,13%) follwed by Cymbella (10,43%). Based on the preference viewed from the Largest Index, the natural forage for the bivalve of < 30 mm length, Oedogonium and Detritus were considered as the main food, meanwhile, for the bivalve of > 50 mm length, Detritus was as the main food. Based on the result of data analysis, it was revealed that the main forage for Polymesoda bengalensis was Detritus and Oedogonium.
