ABSTRAKTujuan penelitian ini adalah untuk mengetahui pembelajaran tematik menggunakan pendekatan saintifik dengan media lingkungan sekolah sehingga dapat meningkatkan keterampilan proses siswa. Penelitian ini menggunakan metode penelitian tindakan kelas (PTK). Rancangan penelitian tindakan kelas yang diambil yaitu model siklus, yang pada setiap siklus terdiri atas perencanaan, tindakan, observasi dan refleksi. Subyek penelitian adalah siswa kelas IV di salah satu Sekolah dasar (SD) di Magelang. Teknik analisis data yang digunakan adalah teknik analisis data deskriptif kuantitatif. Data keterampilan proses dan penguasaan konsep siswa dideskripsikan dalam persentase kemudian diklasifikasikan dalam kategori untuk mengetahui tingkatan keberhasilan setiap aspek penilaian. Hasil penelitian menunjukkan bahwa rata-rata hasil penilaian keterampilan proses sains siswa pada siklus I adalah 84,5% sedangkan pada siklus II adalah 87,1%. Dari hasil penelitian ini dapat disimpulkan bahwa Pembelajaran tematik menggunakan pendekatan saintifik dengan media lingkungan sekolah dapat meningkatkan keterampilan proses siswa, sehingga dapat meningkatkan kualitas pembelajaran khususnya pada tema Peduli terhadap Makhluk Hidup dan subtema Ayo Cintai Lingkungan Kata kunci: keterampilan proses sains, media lingkungan sekolah, pembelajaran tematik saintifik ABSTRACTThe objective of this classroom action research was to identify impact of the implementation of curriculum 2013 on science thematic learning by using school environment media to improve students' science process skill. Classroom action research design The design of the classroom action research applies cycle model that, consists of planning, action, observation and reflection steps. Research subjects were fourth grade students in one of elementary schools in Magelang. Data analysis technique was quantitative and qualitative descriptive data analysis. Science process skill data of the student were described in percentage and then classified in categories to describe the achievement level of each assessment aspect. Students' science process skills in cycle I was 84.5% whereas in cycle II was 87.1%, therefore we concluded that the implementation of curriculum 2013 on scientific thematic learning by using school environment media can improve students' science process skill, in which it increased learning quality in "Peduli terhadap Makhluk Hidup" theme and "Ayo Cintai Lingkungan" subtheme.

The purpose of this study is to estimate the population of fish of the genus Tor as a source of proper domestication. Bioinformatic analysis was carried out by extracting data from the NCBI gene bank and alignment of the Cytb gene sequences using the ClustalW program to further analyze the nucleotide characteristics using MEGA software, determining genetic variation using the dnasp5 software, and using median joining analysis to reveal the relationship between Tor fish haplotypes from different locations. The results obtained from this study show that the haplotype diversity values of fish of the genus Tor spp. in the domesticated farm population and the natural population are still high, namely 0.9 and 0.8, respectively, as well as the occurrence of haplotype groupings based on other population origins. Domestication of Tor genus fish can be sourced from domesticated farms, and the wild is still ideal because the haplotype diversity is still high.

This study aims to analyze the needs of the Development of Discovery Learning Model Based on Naturalist Intelligence. The research was conducted using a survey method. The research subjects were 20 Elementary Schools, involving 20 teachers and 180 students. The focus of the assessment is the teacher's response to the development of the Discovery Learning model based on naturalist intelligence and student scientific literacy. Data were collected by interview, questionnaire, observation. Data were analyzed descriptively quantitative. The results of the analysis show that (1) the principal supports efforts to develop a learning model as a form of adaptation to learning changes due to the COVID-19 pandemic, (2) the teacher supports and states readiness to be involved in development, (4) the students' scientific literacy is categorized as lacking. The implication is the development of Naturalist Intelligence Based Discovery Learning to Improve Students Science Literacy.
