    Keterampilan berpikir kladistik, keterampilan berpikir kritis, dan penguasaan konsep merupakan kompetensi yang diharapkan dikuasai oleh mahasiswa setelah mempelajari zoologi vertebrata. Hal ini pun sejalan dengan dengan kompetensi dan literasi sains abad 21. Oleh karena itu, penelitian ini bertujuan untuk mengimplementasikan program perkuliahan berbasis representasi filogenetik dan team-based learning (RF-TBL) yang dapat membekalkan keterampilan berpikir kladistik, keterampilan berpikir kritis dan penguasaan konsep mahasiswa. Penelitian ini menggunakan mix method dengan embeded experimental model control group design. Subjek penelitian adalah mahasiswa yang mengikuti mata kuliah zoologi vertebrata pada semester genap tahun akademik 2015/2016, kelas eksperimen berjumlah 40 orang dan kelas kontrol berjumlah 45 orang yang ditetapkan secara purposive sampling. Berdasarkan Hasil perhitungan N-gain () menunjukkan bahwa terjadi peningkatan keterampilan berpikir kladistik mahasiswa (nilai = 0.76, ketegori tinggi), keterampilan berpikir kritis ( = 0.7, kategori tinggi) dan penguasaan konsep mahasiswa (nilai = 0.6, kategori sedang). Pengujian satistik menunjukkan terdapat berbedaan signifikan antara kelas kontrol dan kelas RF-TBL, di mana kelas RF-TBL lebih baik dibandingkan dengan kontrol. Hal ini berarti bawah implementasi RF-TBL memberikan pengaruh yang signifikan terhadap peningkatan keterampilan berpikir kladistik, berpikir kritis dan penguasaan konsep mahasiswa. Mahasiswa juga memberikan respon positif terhadap diimplementasikannnya strategi perkuliahan RF-TBL dalam mata kuliah zoologi vertebrata. Uji korelasi menunjukkan terdapat hubungan positif antara keterampilan berpikir kladistik, keterampilan berpikir kritis dan penguasaan konsep mahasiswa. Berdasarkan penelitian ini juga diketahui bahwa mahasiswa menganggap membuat pohon filogenetik lebih sulit dibandingkan dengan membaca pohon filogenetik. ---Tree thinking skills, critical thinking skills, and students concepts mastery are competencies expected to be mastered by students after studying vertebrate zoology. This is also in line with the competence and science literacy of 21st century. Therefore, this research aims to implemented course program based on phylogenetic representation and team-based learning (RF-TBL) which can improve the tree thinking skill, critical thinking skill, and student concept mastery. This research uses mix method with embedded experimental model control group design. The subjects of the study were the students who enrolled the vertebrate zoology course in the even semester of 2015/2016. The experimental class was 40 students and the control class was 45 students determined by purposive sampling. The results show that there was an increase in students' tree thinking skills, critical thinking skills, and student mastery concepts after being calculated using N-gain. The statistic calculation shows that there is a significant difference between the control and experimental classes, where the experimental class is better than the control. This means that the implementation of RF-TBL has a significant influence on improving the tree thinking skills, critical thinking skills, and mastery of student concepts. Students also responded positively to the implementation of RF-TBL strategy in vertebrate zoology courses. Correlation test shows there is a positive correlation between the tree thinking skills, critical thinking skills and mastery of student concept. Based on this study, it is also known that students consider constructing phylogenetic trees more difficult than reading phylogenetic trees

    Pakan merupakan biaya produksi terbesar, seoptimal mungkin harus ada energi alternative yang dapat menggantikan pakan, salah satunya yaitu dengan memanfatkan limbah singkong yang diproduksi menjadi bioetanol dengan proses fermentasi sehingga pakan bernilai gizi tinggi. Penelitian ini bertujuan untuk meningkatkan kualitas nutrisi limbah bioetanol singkong melalui fermentasi dengan menggunakan jamur Aspergillus niger yang mempunyai kemampuan untuk fermentasi. Limbah bioetanol masih mengandung racun asam sianida yang merugikan ternak dan berdasarkan hasil analisis limbah bioetanol bahwa terdapat kandungan asam sianida (HCN) 15,92 mg/kg, protein 2,74%, serat kasar 2,65%,sehingga kualitas zat makanannya masih rendah, maka sebelum diberikan pada ternak perlu dilakukan proses pengolahan melalui fermentasi dengan menggunakan jamur Aspergillus niger. Metode yang di lakukan adalah metode eksperimen limbah bioetanol singkong selama 0, 4, dan 9 hari dengan 4 konsentrasi mikroorganisme yaitu 2, 3, dan 4%. Penelitian sebelumnya Parameter yang diamati adalah jumlah mikroba, jumlah kandungan protein kasar dan kandungan serat kasar limbah bioetanol produk fermentasi melalui analisis proksimat. penelitian menunjukan bahwa protein tertinggi sebesar 4,507%, penurunan kadar serat terendah mencapai 1,293%, dan penurunan HCN sebesar 0,000 mg/kg

    Effective learning and applying the daily life problem solving principle that emphasizes that learning needs to be designed so that students are able to solve problems related to daily life. Problem solving skills can be improved by doing variations in the learning model, one of the learning models that can be applied is the problem solving model. This study aims to find out the problem solving skills of students on material changes in the environment after carrying out learning with problem solving models, as well as to find out the process of implementation and constraints of students in learning activities. The research method used is the pre-experimental method with the design of one group pretest-posttest. The sample used is students of class X MIA 1 with a total of 34 people. The research instrument used was a written test about 10 questions, observation sheets and questionnaires. The results showed that the written test results obtained an average value of N-Gain of 0.54 moderate qualifications. Paired t test results obtained t count (15.39) > t table (2.03) so that H0 is rejected which means that with α = 5%, there is a significant difference between students' problem solving skills before and after applying problem solving learning models on material changes in the environment. The application of problem solving learning models can help students to improve their problem solving skills.Keywords: Problem Solving Skills, Problem Solving Learning Models, Environmental ChangeAbstrak: Pembelajaran yang efektif dan menerapkan prinsip the daily life problem solving yang menekankan bahwa pembelajaran perlu dirancang agar peserta didik mampu memecahkan masalah yang berhubungan dengan kehidupan sehari-hari.

    This research generally is aimed to recognize the students’ concept mastery on ecosystem material by usingthe Problem Posing Learning (PPL) based on science fables and its influence on the students and student responses anddelays in learning were carried out using the PPL-DS model. The research method used is quasi-experimental method.Moreover, the research design used in this current research is nonequivalent control and samples were taken bypurposive sampling technique. Test, questionnaire, and observation sheet are used as the instruments. Research dataanalysis includes several tests such as normality, homogeneity, hypothesis, and N-Gain. Data were obtained from 20questions for each pretest and posttest. The result gained from the class using the research model has moderatedcriteria with an N-gain average of 0.35 while the class with non-research model has a low criterion with an N-gainvalue of 0.21. The implementation of activities carried out by students and teachers is fairly good with 84.21% and88.23% achieved. The response shown by students is also quite satisfactory with a value of 86.20% high criteria.
