Abstract

Lighting is an important parameter of the poultry production because of strong exogenous factor in controlling a wide variety of physiological processes and behavior. The lighting allows the birds to establish harmony and sync or equate many essential functions, including body temperature and various steps that facilitate metabolic feeding and digestion. The lighting also stimulates the secretion of some hormones patterns that control most of the growth, maturity or adulthood and reproductionThis research aims to assess the influence of light color on the body weight and carcass kampung chicken. The main independent variable is the color red, blue and white. The main dependent variable consists of body weight and percentage of carcass. The variable control is the number of rations, health management, a type of chicken, and the age of the chicken.The results show that there is no real difference in the influence of different color variations of the lighting body weights (P>0,05), and the carcass of a chicken (P>0,05).Keywords : lighting stimulation, kampung chicken, body weights, carcass

Abstract

The learning processof biodiversity insome schoolsit is lessoptimal, especially in theuse of learning sources. The natural reserveis anatural environments potential as a sources oflearning. The natural reserveUlolanangKecubunghasa highbiodiversity, including diversity of ecosystems, species andgenetic. Ecosystemdiversity includesnatural ecosystems, semi-naturalecosystemsandartificial ecosystems. Species diversity includes various types of vegetation such as trees, shrubs, epiphytes, lianas, ferns, and various types of animals such as long-tailed monkeys, butterflies, birds, and so forth. In addition to high biodiversity, nature reservation Ulolanang Kecubung very easy reach so it is ideal for use as a learning sources.Keywords:natural reserve, biodiversity, learning sources

Abstract

A study with R & D method focusing on improving the skills of arguing in the concept of human physiology was conducted through the development of model of Assessment Argumentative. The model was outlined in the form of argumentation observation sheet(LOAKp). A number of sixth semester students of Biology Education attending subject of Human Physiology (n=121) were involved as research subject. The implementation study applied Research and Development design. TAP (Toulmin Argumentation Pattern) comprising components of claim, warrant, backing and rebuttal had been used to analyze argumentation discourse. Arguing skills were qualitatively and quantitatively measured by complexity of argumentation pattern (PWArKp). The instrument of assessment argumentative model as observation sheet of argumentation discourse which had been implemented through stages (scaffolding) with particular standpoints. The results show that the aspects of PWArKp are generally developed from the early stages to the final stage. However, complexity of argumentationdiscourse still need to be improved because some standpoints have responed on level 1 or leve 2. Thus skills of arguing of students in complexity of argumentation pattern aspects need further in depth study by providing students more opportunities to engage in argumentative discourse.Key words: Assessment Arguementative, argumentation skill, human physiology concepts

Abstract

Biological gardens Seungko Mulat is an area in Aceh Besar district Lhoong that have different types of plants in vegetation dominance by species of Angiosperm. This study aims to determine the kinds and diversity of plants Angiosperm contained in the biological garden Seungko Mulat Lhoong Aceh Besar district. The research was carried out in the biological garden of Seungko Mulat used exploratory survey method for this kind of tree, as well as squares method for herbs and shrubs. Analysis of the data by calculating the index of diversity and importance value. The results showed that in the study area, there are 9 species Angiosperm that herbs, 13 species of shrubs and 10 species of trees. The most dominant type of Angiospermae is Paspalum conjugatum, Mimosa pudica, Eupatorium oderatum and Etlingera littoralis. Index Angiosperm species diversity is low to moderate for herbs and shrubs. The necessity for herbs are 92.54 and 69.22 for the bush.Keywords: Diversity, Angiospremae, Seungko Mulat

Abstract

Activity lesson study is one means for faculty to enhance professionalism in the learning activities. Through lesson study activity which consists of three stages: plan, do and see, teachers can enhance learning systematically, and can build pedagogical knowledge. This study aims to develop an invertebrate zoology course in learning biology using model based learning DARTs (Directed Activities Related to Texts), or activities which are directed to read the text or reading. Through learning-based invertebrate zoology DARTs expected to increase students' critical thinking skills and create effective learning.Learning-based invertebrate zoology Darts begins by compiling Student Worksheet together with lesson study teams, then the Student Worksheet to classroom study tested twice.The model of Invertebrate zoology learning best on DARTs through Lesson Study can helped teacher to develop Students work sheet. This can be seen in the increase in observations of students is increasing. Critical thinking skills can help students to understand the material presented so that invertebrate zoology student understanding can be fully or thoroughly.Keywords: Learning Development Invertebrate Zoology, DARTs (Directed Activities Related to Texts), Lesson Study.

Abstract

Joint fir (Gnetum gnemon L.) is one of forestation plant on Java is associated with ectomycorrhizal fungi such as Scleroderma spp. In mutualistic symbiosis. Scleroderma associated with joint fir is commonly called jamur so or jamur melinjo by Javanesse people. Research on Scleroderma fungi characterization and classification in Indonesia, especially in Java is very limitted. The sample of characterization were collected from Pacitan Regency, East Java Province. Characterization of Scleroderma spp. were used macroskopic and microscopic characters from fruiting bodies, spores and infected roots of joint fir. There are three morfological character types of Scleroderma fungi associated with jont fir from Pacitan Regency.Key words: morphological characters, ectomycorhizal fungi, Scleroderma spp., Gnetum gnemon L.
