Learning in the 21st century demands the increasing of students' creativity in solving problems in the environment. Creating products of economic value by applying the socio-scientific issue (SSI) learning approach can be applied in learning about biotechnology at the high school level. This study aimed to design a learning resource for teaching biotechnology which promoting the issue of SSI and nurturing the entrepreneurship of the student as well. Indonesia has the potential to develop native chicken farming to increase the economy status and people's income, but the productivity of native chickens is still low. To solve the problem, an organic feed based on rice bran and papaya leaves which have high nutritional content were introduced as one of the projects which can be run by high school students. To find the potential of papaya leaves and rice bran, a literature review had been done. The results shows that papaya leaves are rich in protease enzymes so that they can increase the digestibility of amino acids in chickens. Bran contains phytic acid as an antinutrient. The smell of ammonia cannot be separated from the problem of livestock. Production of feed from the fermentation of bacteria Bacillus subtilis and Lactobacillus bulgaricus can add phytase enzymes to increase nutrient absorption to accelerate the increase in chicken weight. Fermented feed is also able to inhibit bacteria that break down protein into ammonia so that the smell of feces disappears. Based on these findings, the learning activities for understanding the concepts of biotechnology is need to be further designed.

Biology teachers and students in society 5.0 are expected to show critical thinking skills (CTS) in solving problems or making decisions. Thus, it is important to know how the CTS are nurtured through online learning. The trend of studies on these issues needs to be explored. This research aims to map the trend of studies on nurturing the CTS through online learning by reviewing some articles published within 2018-2020, considering 1) the online learning, 3) topics in biology, 4) teaching methods, and 5) instruments of CTS. Following the systematic review of the PRISMA Method, articles were screened from Google Scholar. The keywords were "critical thinking", "biology education", "online learning", and "Indonesia", which resulted in 23 articles to be further reviewed. The findings show that CTS's research trends using online learning have increased due to the COVID-19 pandemic that requires students and teachers to distance studies. The most used online learning was digital learning. The researchers used various topics in biology to measure students' CTS using online learning but mainly genetics and cell biology. The most widely used teaching method is blended learning and online discussion which various learning models can combine learning methods or learning media. The test is mainly used as an instrument to measure CTS with various indicators presented by experts. Research on CTS using online learning needs to be further explored to increase the quality of the study

Lemahnya argumentasi ilmiah mahasiswa dalam pembelajaran telah banyak menjadi perhatian, terutama dalam hal mengevaluasi dan mengkonstrak permasalahan dan solusinya. Penelitian ini bertujuan untuk mengetahui bagaimana profil keterampilan argumentasi ilmiah mahasiswa pada mata kuliah Anatomi Tumbuhan. Penelitian ini merupakan penelitian deskriptif untuk mendapatkan gambaran keterampilan argumentasi mahasiswa semester 3 di Prodi Pendidikan Biologi FKIP UNS melalui tugas tertulis yang diberikan. Penilaian argumentasi mahasiswa mengacu pada Toulmin’s Argumentation Pattern (TAP) yang memuat komponen claim, evidence, reasoning dan rebuttal. Hasil penelitian menunjukkan bahwa kemampuan argumentasi ilmiah mahasiswa Pendidikan Biologi FKIP UNS masih tergolong rendah, dibuktikan dengan skor rerata claim sebesar 52%, evidence sebesar 42%, reasoning sebesar 15% dan rebuttal sebesar 10%. Temuan ini akan dijadikan dasar bagi penelitian lanjutan mengenai model dan strategi pembelajaran inovatif yang dapat meningkatkan kemampuan argumentasi dan penalaran ilmiah terutama bagi calon guru biologi.

Penelitian bertujuan mengetahui pengaruh pembelajaran problem based learning terhadap penguasan fakta, konsep, prosedur dan metakognisi pada pembelajaran problem based learning pada pelajaran biologi. Penelitian merupakan quasi eksperiment dengan populasi penelitian adalah peserta didik kelas 10 SMAN 4 Surakarta, dengan 2 kelas sebagai sampel penelitian kontrol dan perlakuan. Penentuan sampel menggunakan purposive random sampling untuk dua kelas yang mempunyai kesamaan kemampuan dengan uji F(32;0,05)=3,998. Analisis pertanyaan peserta didik sebelum dan sesudah menggunakan pembelajaran problem based learning menggunakan kualifikasi pertanyaan berdasarkan Taksonomi Bloom. Data dianalisis dengan anacova. Hasil penelitian menunjukan bahwa pembelajaran problem based learning mempengaruhi penguasaan pertanyaan ditinjou dari jumlah pertanyaan pada pengetahuan fakta, konsep, prosedur namun tidak untuk metakognisi.

This research aims at exploring the contribution of the shade of treetowards the density of earthworms. The convertionof forest into a farmland causeda change in the shade of tree from a closed into an open ecosystem that was predicted to be followed by the decrease of earthworms density. The kinds of land thatis used for research are forest, complex agroforestry, simple agroforestry, teak monoculture, teak-accacia polyculture, and peanut crops. The data were analyzed quantitatively using statistical methods by SPSS 0.16. The results show that the wide oftree shade contributes to the density of earthworms on rainy season as much as 71.5% and also contributes to the density of earthworms on dry season as much as 52.2%. From the results, it can be concluded that the shade of tree has a strong role towards the density of earthworms.
