STUDENT TEAM ACHIEVEMENT DIVISIONS (STAD) and GROUP INVESTIGATION (GI) LEARNINGS in ECOSYSTEM SUBJECT EVALUATED FROM ENVIRONMENTAL ATTITUDE  ABSTRACT The aims of this research are to know : (1) The difference of student’s achievement learn on ecosystem subject between student who learn with cooperative method learning STAD and student who learn with cooperative learning GI, (2) The effect of low, middle, and high environmental attitude towards the student’s achievement learn on ecosystem subject, (3) The interaction between usage of cooperative method learning STAD and GI with environmental attitude towards the student’s achievement learn in ecosystem subject. This research’s subjects were students of class 10th in SMAN 3 Sukoharjo This research used factorial design 2x3 anava with different cell frequency. According to the result of this research, it shows that: (1) Usage STAD learning’s method produces better student’s achievement learn than GI learning’s method. (2) Environmental attitude influence the student’s achievement learn. (3) There is no interaction between the use of learning method and environmental attitude towards the student’s achievement learn. Key word : STAD, GI, environmental attitude   ABSTRAKTujuan dari penelitian ini adalah untuk mengetahui: (1) perbedaan prestasi siswa belajar pada subjek ekosistem antara siswa yang belajar dengan metode pembelajaran kooperatif STAD dan siswa yang belajar dengan pembelajaran kooperatif GI, (2) Pengaruh rendah, menengah, dan sikap lingkungan yang tinggi terhadap prestasi belajar siswa pada mata pelajaran ekosistem, (3) interaksi antara penggunaan metode pembelajaran kooperatif STAD dan GI dengan sikap lingkungan terhadap prestasi siswa pelajari dalam pelajaran ekosistem. Subjek dari penelitian ini adalah siswa kelas X SMAN 3 Sukoharjo. Penelitian ini menggunakan desain faktorial 2x3 anava dengan frekuensi sel yang berbeda. Berdasarkan hasil penelitian ini, menunjukkan bahwa: (1) Penggunaan metode pembelajaran STAD yang menghasilkan prestasi belajar siswa lebih baik kita belajar dari metode pembelajaran GI itu.

PROBIOTICS CULTURE GROWTH OF ISOLAT NON PATHOGENS BACTERIA IN VARIOUS TYPES OF MEDIA  ABSTRACT Application of probiotics as biosecurity is the safest way to tackle disease in fish and shrimp farming because of bacteria used are organisms that can degrade toxic organic material in the water .Bacillus sp is a type of bacteria that can be used as a probiotic agent because of its ability to degrade organic compounds for the sake of growth . This study aims to determine type appropriate media types for the growth of probiotic bacteria Bacillus sp. The method used in this research that completely randomized design (CRD) with 4 treatments and repeated 4 times. The treatments were the addition of soy extract, sprouts, and potatoes. The results showed that there were significant differences on each treatment with the addition of soy extract, sprouts, and potatoes in the probiotic culture medium. The conclusion of this study indicate that the type of media that is most optimal to extract the green bean sprouts reach a value of OD (Optical Density) 0.68. Keyword: Probiotics, Bacillus sp.  ABSTRAK Aplikasi probiotik sebagai biosecurity merupakan cara yang paling aman untuk mengatasi serangan penyakit pada ikan maupun udang budidaya karena bakteri yang digunakan merupakan organisme yang mampu mendegradasi bahan organik yang bersifat racun dalam air. Bacillus sp merupakan jenis bakteri yang dapat digunakan sebagai agen probiotik karena kemampuannya dalam mendegradasi senyawa organik untuk kepentingan pertumbuhan. Penelitian ini bertujuan untuk mengetahui jenis media yang sesuai untuk pertumbuhan bakteri probiotik jenis Bacillus sp. Metode yang digunakan dalam penelitian ini yaitu rancangan acak lengkap (RAL) dengan 4 perlakuan dan diulang 4 kali. Perlakuan yang diberikan adalah dengan penambahan ekstrak kedelai, kecambah kacang hijau, dan kentang. Hasil penelitian menunjukkan bahwa ada perbedaan yang signifikan pada masing - masing perlakuan dengan penambahan ekstrak kedelai, kecambah, dan kentang pada media kultur probiotik. Kesimpulan dari penelitian ini menunjukkan bahwa jenis media yang paling optimal yaitu dengan pemberian ekstrak kecambah kacang hijau dengan mencapai nilai OD (Optical Density/Kerapatan Optik) 0,68. Kata Kunci : Probiotik, Bacillus sp.

A mix between the computer software which isdesigned to represent an alternative implementation concept of VirtualLaboratory. Through KD 3.4. Applying the Classification to classifyarchaebacteria and eubacteria based on characteristics and shapethrough systematic observation. It selected the Gram staining processin bacteria, which is to find groups of bacteria including GramPositive or Negative. The media influenced learning process in manysection, it is possible that the virtual lab used as a means to internalizethe values of character. This research’s aim was to producedLaboratory Virtual Media Instruction, which was oriented formcharacter building through the development process. The method wasused research and development refers to the flow of Borg and Gall(1989). The results showed increasement in postal value, which isused Laboratory Virtual Media, compared to pre test, but the N-gainwas quite low at 0.2.
