This research is motivated by the low achievement of sciencem literacy of Indonesian students in the participation of the study of The Programe for International Student Assessment (PISA) held every three years by The Organization for Economic Co-operation and Development (OECD). This study aims to determine the quality of science literacy profile of junior high school students. The sample amounted to 356 students of SMP class IX, taken using proportionate stativeied random sampling technique. The Method is test and interview. The tests given using questions obtained from the OECD published PISA issue were published in 2009 specifically for matters related to science content. The results showed that the Literacy Quality of Science Profile of Junior High School Students in Pati Regency belong to low category with percentage of 55%. In the category of moderate percentage obtained by 45% and no students who fall into the high category. As for the achievement of the value of each level, the highest ability of students in answering science literacy questions in the level 1 questions with a total of 49.43 moderate categorized, and the lowest ability of students in answering the questions of science literacy is in level questions 6th with a total of 13.48 is low categorized. The conclusion is the quality of science literacy profile of junior high school students in Pati District is low.

This study aims to determine the effectiveness of membrane transport learning which contains ethnoscience for cognitive learning outcomes and entrepreneurial interests in SMAN 1 Kendal students. The instrument of data collection are question and questionnaire. The results are average pretest score of experiment class is 49,67 and posttest score is 83,50. Besides, control class have 52,17 and 72,33 as average pretest score and posttest score respectively. Both class are classified to medium category based on N-gain value (the value of experiment class is 0,67 and 0,44 for control class). Those class have significant difference result of t test both in posttest score and entrepreneurial interest (p <0,05). The conclusion of this research is that the ethnoscience of salted egg production in membrane transport learning is significantly effective (p <0,05) for cognitive learning outcomes and entrepreneurial interest of SMA N 1 Kendal students. Key words: cognitive learning outcomes, entrepreneurial interest, ethnosains,  salted egg  ABSTRAKPenelitian ini bertujuan mengetahui efektifitas pembelajaran transport membran bermuatan etnosains terhadap hasil belajar kognitif dan minat berwirausaha siswa SMA. Instrumen pengambilan data menggunakan butir soal, dan angket. Hasil penelitian ini adalah rata-rata nilai pretest kelas eksperimen 49,67 dan nilai posttest sebesar 83,50;  pada kelas kontrol rata-rata pretest sebesar 52, 17 dan nilai posttest sebesar 72,33;  N-gain kelas eskperimen maupun kelas kontrol pada kategori sedang, demikian juga pada kelas kontrol (nilai N gain kelas eksperimen sebesar 0,67, kelas kontrol sebesar 0,44); uji t pretest posttest kelas eksperimen maupun kelas kontrol menunjukkan berbeda secara signifikan (p<0,05); uji t posttest kelas eksperimen dengan kelas kontrol menunjukkan berbeda secara signifikan (p<0,05); minat berwirausaha kelas eksperimen dengan kelas kontrol menunjukkan berbeda secara signifikan (p<0,05). Kesimpulan penelitian ini adalah  bahwa etnosains produksi telur asin dalam pembelajaran transport membran efektif secara signifikan (p<0,05) terhadap  hasil belajar kognitif dan minat berwirausaha siswa. Kata kunci : hasil belajar kognitif, minat wira usaha, etnosains, telur asin

Penelitian ini bertujuan untuk mengetahui pengaruh pembelajaran Outdoor learning pada model Discovery learning terhadap hasil belajar siswa kelas X pada materi pencemaran lingkungan. Pelaksanaan penelitian dilakukan pada semester genap tahun ajaran 2016/2017 dengan populasi penelitian yang digunakan yaitu kelas X MIPA SMA Negeri 1 Tahunan Jepara. Sampel yang digunakan yaitu kelas X MIA 3 sejumlah 35 orang sebagai kelas eksperimen dan kelas X MIA 1 sejumlah 36 orang sebagai kelas kontrol. Tehnik sampling yaitu menggunakan cluster random sampling dan metode yang digunakan yaitu quasi eksperimental design dengan desain penelitian nonequivalent control group design. Instrument yang digunakan yaitu test (lembar tes kemampuan kognitif) lembar tes berjumlah 20 soal yang terdiri dari kemampuan menjelaskan, mencontohkan, mengklasifikasikan ketiganya merupakan aspek yang terdapat dalam ranah memahami dan non test (lembar observasi). Lembar observasi digunakan dalam penelitian dengan teknik pengamatan untuk mengumpulan data.

THE EFFECT OF  THE OUTDOOR LEARNING INTEGRATED DISCOVERY LEARNING MODEL OF OUTCOMES AND CONCEPT UNDERSTANDING FOR ENVIRONMENT POLLUTION SUBJECT AT CLASS X STUDENT OF SMA NEGERI 1 TAHUNAN JEPARA Abstract This reseach aims is to understanding the effect of outdoor learning integrated discovery learning model of concept understand and outcomes of class X students, implemented of environment pollution material. This reseach implemented on 2016/2017 with X class student as population in SMA N 1 Tahunan Jepara. The sample consist of X class of 3 MIA with 35 pupils for experiment class and X class of MIA 1 with 36 pupils for control class. This study used cluster random sampling technique. This reseach used cluster random sampling technique to take of sample. The desaign of this research was Quasi Experimental with Nonequivalent control Group Design. The result of T test of pretest is not real difference. While, the T test of postest result is good effected of cognitif outcomes  and concepts understanding. The data obtained is tcount 2.891, ttable 1.67 and tcount 5.548, ttable 1.67, accordingly, both of them accepted. The data show tcount ?ttable. Its mean the data is significant.

Tofu industrial waste has the potential to become contaminant when it is not maximum processed, so it needs appropriate treatment to minimize the occurrence of pollution. β-Glucans can be produced from the yeast cell wall of Saccharomyces cerevisiae.As a feed supplement, β-Glucans have been used for an immunostimulant because it can increase the immune system. This study aimed to establish a suitable technology to produce β-Glucans fromSaccharomyces cerevisiae by utilize tofu waste as feed supplement. The Completely Randomized Design (CRD) model was used in the experimental method. This study used an experimental method with a Completely Randomized Design (CRD) model.The treatment given wereP1: 1kg of tofu waste + 1kg of bran +0.2 kg fish meal + 0.2 lt molasses + 5.5 gSaccharomyces cerevisiae; P2: 1kg of tofu waste + 1kg of bran +0.2 kg fish meal + 0.2 lt molasses + 6.5 g Saccharomyces cerevisiae; P3: 1kg of tofu waste + 1kg bran + 0.2 kg fish meal +0.2 lt molasses + 7.5 g Saccharomyces cerevisiae. Each treatment was repeated 3 times, and fermented for five days.The results found that P1 by Saccharomyces cerevisiae 5.5 g was the best formulation to produced crude β-Glucans by weight of 25.9 g/kg of waste. Production of β-Glucans as an animal feed supplement is a waste-based feed technology development which is expected to increase livestock production both in quality and quantity.
