Abstract

Leaves are an important organ for plants. One part of leaf is stomata which function as a place for gas exchange. The method used in this research is the observation of the morphology and anatomy of frangipani leaves (Plumeria acuminata) which are exposed to pollution and not exposed to pollution. The purpose of this study was to determine environmental conditions or as a bioindicator by observing damage to plants. Macroscopic damage to plants in leaf morphology and microscopic damage to changes in leaf stomata conditions. Observations show that the morphology of frangipani leaves (Plumeria acuminata) which are not exposed to pollution is larger than frangipani leaves (Plumeria acuminata) which are exposed to pollution. The number of stomata in the abaxial part is more than the adaxial part. Meanwhile, the number of stomata on frangipani leaves (Plumeria acuminata) that were not exposed to pollution was more than those exposed to pollution. The stomata type on frangipani leaves (Plumeria acuminata) is anomocytic type with kidney-shaped covering cells.

Abstract

The people of Bondowoso Regency are dominated by Madurase, which is 90%. The majority of Madurase in Bondowoso Regency own cattle. The Madurase community is Grujugan Subsdistrict, Bondowoso Regency still maintains ancestral traditions for the care and treatment of cattle, so there is a need for scientific studies on the use of plants for traditional livestock so it will not extinct. The purpose of this study was to determinate the plants used for the care and treatment of cattle, how to process them, the presence of a mixture of other non-plant material in the feed making or traditional medicine of cattle, the types of diseases commonly experienced by cattle, and the types of plants used for cattle feed. This type of research is descriptive exploratory, with a survey method that uses semi-structured interview techniques. The study was conducted in two villages, named Sumber Pandan Village and Wanisodo Village using 18 respondents. The results of the study are inventorying 20 plants species and 14 families that are used for traditional treatment and care of livestock and 9 types of additives use for bleeding in the manufacture of livestock medicine. In addiction there are also 16 species of plants and belong to 8 families that are used for cattle feed by the Madurase Tribe Society in Grujugan District, Bondowoso Regency.

Abstract

Agroecosystem plays an important role in the national economy. However, the role of agroecosystem in education in the form of teaching and learning has not been used optimally. It is less in providing opportunities for students to develop their mindset based on their abilities so that the students do not understand the potential requiring the surrounding area. Learning models that can provide opportunities for students to develop are suitable with the 2013 curriculum. Modification of collaborative learning Cells with Brain-Based Learning (BBL LC) model makes the learning appropriate for the 2013 curriculum. The purpose is to obtain a valid, effective, and practical model which is suitable for the junior high school science learning in the agroecosystem area. The research type is development research (R & D) by using the 4-D model but, only use three stages; Define, Design, and Develop stages without using Disseminate stage. This research was conducted at Junior High School 7 Jember. The data collection techniques were filling out the validation sheet, interview, observation, test, and documentation. The data analysis techniques include data analysis from the validation results, model analysis, and model effectiveness analysis. The model validity was the average results of the product validation (85.81%) in a very valid category. The model effectiveness was the average of¬N-gain learning outcomes (0.53) and students' problem-solving skill questionnaires (75.87% ) in a good category. The model practicality was from the teacher and student response questionnaires with an average of about 92.94% and 94% which belongs to a very practical category.
