Abstract

Lighting is an important part of poultry production. Lighting is a powerful exogen-ous factor in controlling many physiological and behavioral processes. Lighting is the most critical factor of all the environmental factors for poultry. The research aims to (1) assess the influence of intermittent lighting in intensive maintenance chickens on chicken that has been commonly maintained by to let loose (removed), (2) examine how to overcome the possibility of stress that arise in chic-kens which are usually removed, then maintained in a way grounded. The study design used was completely randomized design (CRD) in time, with three treatments are: C1 = illumination 1L: 3D: C2 = lighting 2L: 2D; and C3 = lighting 12L: 0D. Each treatment was repeated four times. The parameters studied were body weight, technique tonic immobility, and mortality. Data were analyzed and interpret- ted by analysis of variance. The results are, the imposition of intermittent lighting on the maintenance of inten-sive chicken on a scale of households, providing a positive and beneficial influence on the production aspect of weight loss and mortality. Intermittent lighting will mi-nimize the risk of stress in chickens as seen on tonic immobility technical para-meters of this study. The best performance results seen in treatment C1 (1L: 3D), the treatment of intermittent one-hour light, and 3 hours of darkness each day, from 18:00 until 06:00 hours for 10 weeks, starting the second week of the study. The conclusion is intermittent lighting treatment in the intensive maintenance chic-kens on chicken that has been commonly maintained by to let loose positive effect that can increase body weight, reduce mortality and minimize the risk of stress.Keywords: Chicken, intermittent lighting, tonic immobility

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

MAKE A MATCH IN COOPERATIVE LEARNING TO ENCHANCE THE PROTISTA CONCEPT UNDERSTANDING OF SENIOR HIGH SCHOOL STUDENTS ABSTRACT Learning process in Biology High School has been improve, but there?óÔé¼Ôäós still obstacles in the concept of understanding. It looks phenomenon, because object in biology are living things, while not all objects can be presented in class. These conditions make teachers use Teacher Centered Learning method. This method was meaningful learning for students, when students complete the process, none of the concept to be understand by student. Class X?óÔé¼Ôäós learning outcomes in subject Kingdom Protista is 65% from average student did not reached the KKM, its made students followed the remedial program. Make a Match is the examples method to solve it. Make A Match is a cooperative learning model which the implementation was the students found the right partner to make a?é?á fun concept. This model enhance d student?óÔé¼Ôäós learning motivation and curiosity about the differents in Protista Kingdom, its also improve the evaluation and learner activities. It can be seen from the results, Make A Match learning methods improved the written evaluation?óÔé¼Ôäós result 102% and 84% KKM. This method also improve the skills and creativity of the students ?é?á5%. Keywords: Cooperative, Make A Match, Concept Understanding, Protista ABSTRAK Proses pembelajaran Biologi SMA telah mengalami berbagai penyempurnaan, tetapi masih ada kendala dalam memperoleh pemahaman suatu konsep. Tampak fenomena, karena objek yang dipelajari dalam biologi seluruhnya adalah mahluk hidup, sementara itu tidak semua objek dapat dihadirkan di kelas. Kondisi demikian menyebabkan sebagian besar guru?é?á mengajar dengan teknik pembelajaran yang berpusat pada guru (Teacher Centered Learning). Pembelajaran yang demikian kurang bermakna bagi siswa, sehingga ketika siswa selesai mempelajarinya, tak satupun konsep tertinggal dalam pemahaman mereka. Hal ini tampak pada rendahnya hasil pembelajaran Kingdom Protista di kelas X, yaitu 65% siswa dari rata-rata kelas X?é?á di sekolah masih belum mencapai KKM sehingga siswa-siswa tersebut harus mengikuti program remidial. Make a Match adalah salah satu metode untuk mengatasinya. Metode pembelajaran Make A Match adalah metode dari model pembelajaran kooperatif yang dalam pelaksanaannya para siswa mencari pasangan yang tepat mengenai suatu konsep secara menyenangkan (fun). Dengan cara pembelajaran yang menyenangkan ini, dapat meningkatkan motivasi belajar dan keingintahuan siswa tentang berbagai macam organisme dalam kingdom protista, sehingga dapat meningkatkan hasil evaluasi dan aktivitas siswa. Hal ini dapat dilihat dari hasil penelitian bahwa metode pembelajaran Make A Match mampu meningkatkan hasil evaluasi tertulis sebesar 102%, disertai meningkatnya KKM mencapai 84%. Selain itu metode ini juga dapat meningkatkan ketrampilan dan kreativitas siswa sebesar 5%. ?é?á Kata Kunci: Cooperative, Make A Match, Pemahaman Konsep, Protista
