Creative thinking skill and scientific attitude are one of 21st century skills which have to be taught to students in the learning process. The pre-study result indicated that only a few of learning process is provided by scientific activities which can assist students to comprehend the concepts easier and improve the students’ creative thinking skill and scientific attitude. Inquiry-based learning can be an alternative to provide an active and authentic scientific learning process. This study aims at improving creative thinking skill and scientific attitude through inquiry-based learning in basic biology lecture toward students of biology education. This study is included in a descriptive quantitative research. The research focused on the topic of cell transport which was taught toward 25 students of Biology 2 class from 2017 academic year of Biology Education Department. The learning process was conducted in two meetings on November 2017. The enhancement of students’ creative thinking skill was determined by one group pre-test and post-test research design using test instrument meanwhile the scientific attitude focused on curiosity and objectivity were observed using non-test instrument. Research result showed that students’ creative thinking skill enhanced highly and students’ scientific attitude improved excellently through inquiry-based learning in basic biology lecture.

Tuntutan keterampilan yang harus dimiliki siswa pada abad  ke-21 salah  satunya yaitu keterampilan berpikir kritis yang dapat didukung oleh kemampuan literasi sains sebagai wadah untuk siswa di Indonesia agar mampu bersaing dan dapat menjawab tantangan dari perkembangan zaman. Tingkat literasi sains siswa di Indonesia menjadi perhatian penuh karena masih rendah. Pemilihan media pembelajaran yang tepat, yaitu Microsoft Office Sway dapat memberi harapan dan mampu meningkatkan kemampuan literasi sains peserta didik sehingga mampu menjadi bekal untuk dapat menjawab segala persoalan dalam kehidupannya. Tujuan penelitian ini menghasilkan media pembelajaran berbasis microsoft office sway yang layak untuk melatihkan kemampuan literasi sains. Penelitian ini menggunakan model 4-D (Define, Design, Develop dan Diseminate), tanpa tahap Diseminate. Jenis penelitian ini adalah penelitian pengembangan. Pengembangan media dilakukan di jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Surabaya. Validitas media pembelajaran berbasis microsoft office sway meliputi parameter penyajian, validitas isi dan validitas bahasa. Data hasil penelitian ini dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa media pembelajaran berbasis Microsoft Office Sway yang dikembangkan  validitasnya  sebesar  84,79%  tergolong  kriteria  sangat  valid.  Berdasarkan  penelitian tersebut, media pembelajaran berbasis Microsoft Office Sway pada materi perubahan lingkungan untuk melatihkan kemampuan literasi sains yang dikembangkan telah dinyatakan valid dan dapat diterapkan pada kegiatan pembelajaran. Kata Kunci: literasi sains, Microsoft Office Sway, perubahan lingkungan.

People in South East Asia region have consumed hard clam for a long time. This clam also actively collected and traded by local people around beaches and estuaries in Indonesia. The purposes of this research were to analyze protein and content of hard clam (Meretrix sp.) collected from Bancaran Estuary, Indonesia and to evaluate the content of lead (Pb) and cadmium (Cd). The sample of clams was collected by hand picking during low tide. Fresh samples of clams were kept in a cool box. Fresh samples of the flesh were taken for analysis of nutrient and heavy metal content as well. The content of fat was analyzed using soxhlet method; meanwhile the protein content was analyzed using Kjeldahl method. In addition, the content of cadmium (Cd) and lead (Pb) in the flesh of hard clam were tested using atomic adsorption spectroscopy. The results indicated of the flesh of hard clam contained fat and protein, namely 3.25±0.42% and 10.26±0.46% respectively. Meanwhile, the content of Cadmium (Cd) and Lead (Pb) were 0.0306±0.0053 ppm and 0.0458±0.0035 ppm respectively. The level of Cd and Pb were lower than the level of maximum acceptable limit. Therefore, it can be concluded that the flesh of hard clam was safe for consumption.

The purposed of this research was 1) described the nutrient quality of organic fertilizer made from water hyacinth with the addition of corncobs waste and soybean dregs, 2) described the difference in quality of the organic fertilizer made from water hyacinth with the addition of corncobs waste and soybean dregs, 3) described the best quality from organic fertilizer made from water hyacinth with the addition of corncobs waste and soybean dregs. The method of this research was experimental with completely randomized design. The experiment consisted of one treatment factor namely the type of raw material water hyacinth which included three types, namely P1: with the addition of corncobs waste; P2: with the addition of soybean dregs; P3: with the addition of corncobs waste and soybean dregs (50%:50% ratio). Each type of treatment was carried out three times so that the sample amounted 9. The measured parameters were nutrient content included C, N, C/N, P, K, and pH. The research was conducted at the Ecology Laboratory, FMIPA, Unesa. Data was analysed by descriptively quantitative and statistically used 1-way Anava. The results showed that 1) Based on the criteria of soil chemical properties, organic fertilizer content has the same quality in elements C, N, K, C/N (very high), pH neutral, and P was very low, 2) There was a difference in the effect of the type of material on the amount of nutrient content of organic fertilizer, 3) Water hyacinth that addition with corncobs waste had a higher amount nutrient in several elements namely C, N, K, C/N. Whereas organic fertilizer with addition soybean dregs had a higher amount of content in the element P.
