Abstract

Livestock waste has a major influence on environmental pollution, if not managed properly, because it will cause a foul odor. Efforts to manage livestock waste have not been successfully carried out completely, so new innovations are needed by utilizing the Eisenia foetida as a reactor to process it into earthworm cultivation medium. Processing of livestock waste with earthworms can produce high economic value cocoon and biomass. To find out the differences in cocoon and biomass production in five types of livestock waste, a research was carried out using a Completely Randomized Design with five treatments and five replications. The results showed that the use of feces of cattle, goats, horses, broiler chickens, and rumen contents as the medium of Eisenia foetida cultivation had a significant effect (P<0.05) on cocoon and biomass production. Duncan's test results showed that the highest cocoon production of 123.0 eggs/nest box obtained on goat feces medium was significantly different (P<0.05) with feces of cattle, horses, chickens and rumen contents. The highest production of earthworm biomass of 1339.0 eggs/nest box obtained in horse feces medium was significantly different (P<0.05) with feces of cattle, goats, chickens, and rumen contents. The conclusion is: 1) to produce the most cocoon using goat feces; 2) to produce the most earthworm biomass using horse feces; 3) to produce the highest weight gain of earthworms using cattle feces; 4) to produce a weight size per head of earthworms using high rumen contents; and 5) the use of feces of broiler chickens is not recommended as a whole (100%) as a medium or feed in livestock waste treatment because it causes all earthworms to die, so they need to be mixed with other medium or feed ingredients.

Abstract

ABSTRACT: The available teaching materials, especially on the homology materials are still limited to the knowledge, not yet emphasized on the process, so some students become passive, and this certainly influences the learning outcomes. Homology deals with organs that have different structures, but they have the same function. This is very much happening around us, for it is very necessary to be discussed and demonstrated so as to maximize student activity. One of the solutions offered is the development of STAD-based teaching materials combined with guided inquiry. Through STAD students can discuss various matters related to homology in the surrounding environment, while through guided inquiry students can demonstrate homology, and certainly better understand the process from formulating the problem, formulating goals, formulating hypotheses, determining data collection, taking data, analyzing up to conclusion. This will certainly improve the mentality and self-confidence of the students. The purpose of this study is to develop STAD-based teaching materials combined inquiry on guided homology material. The type of this research is Research Development using model design of Dick & Carey and Paulina & Purwanto in Paizah (2011). The instrument used in the form of a questionnaire is then analyzed descriptively. The developed teaching materials contain; pre-introduction, introduction, summary, evaluation, and closing. Expert content validation results about 80% content presentation and 85% content presentation with good category, while material expert validation about material feasibility is 90% and material presentation is 87% with very good category. Individual test result of 88,17% with very good category. For that it is concluded that; The development of teaching materials with STAD method combined with guided inquiry on homology material is suitable for use.

Abstract

The change of learning paradigm today from teacher centered to student centered has implication to the assessment system (assessment). Assessment not only relies on tests but also refers to performance in the form of authentic assessment and alternative assessment that is better able to dig information holistically about students' ability either affective, cognitive, or psychomotor aspects. Therefore, it is necessary to understand and implement it in the assessment of biology learning process.

Abstract

LKS which has been applied in schools has made students less developed scientific abilities. Worksheets that are used seem monotonous, use a colorless image, so it looks less attractive. Student worksheets are only given to be done by students, without having to guide students in solving problems contained in worksheets, and the worksheet does not contain what students have to do such as observing, analyzing, synthesizing, solving problems because there is no guidance to conduct experiments and scientific attitudes . So that makes students less able to think scientifically in learning, for that applied Experiment Based Biology Worksheet where Experiment Based Biology Worksheet can increase student activity. The purpose of this study is to apply biological worksheets to improve students' scientific abilities. This research includes Classroom Action Research (CAR) which consists of 2 cycles, each cycle has 4 stages including; planning, implementing, observing, evaluating, and reflecting. The instruments in this study were the learning implementation observation sheet (RPP) and the scientific ability test sheet. Research data were analyzed descriptively. The results of the study showed that the results of the implementation of the Learning Implementation Plan (RPP) in cycle 1 reached 75% in the good category and in cycle 2 it reached 90% in the very good category, while the students' scientific ability data in the first cycle reached 49.06 with the less scientific category , increased in second cycle reached 79.57 with the scientific category. The results of the study concluded that the application of experiment-based worksheet could improve students' scientific abilities.
