The process of learning and understanding of science has relevance to the level of metacognitive awareness. The purpose of this study was to find out whether the use of learning journals have an effect on students metacognitive awareness. This study was quasi-experimental research with non-equivalent pretest-posttest control group design. The subjects of this study were second semester of VII grade students of State Junior High School 5 of Sukabumi in 2017-2018 academic year. Metacoginitive awareness was measured by using Metacognitive Awareness Inventory (MAI). The data obtained from pretest and posttest were calculated into N-gain score. These data were analyzed by using independent t-test. The results showed that N-gain score for metacognitive awareness in experimental and control class were 0.70 and 0.22 in sequence. Meanwhile, the t-test results indicated that there was a significant difference between learning by using learning journals and without using learning journal in increasing students metacognitive awareness. It showed that students metacognitive awareness in the experimental class were better than the control class. It can be suggested that implementing learning journal is potential media in improving studentsâ metacognitive awareness.

Tujuan penelitian ini mengembangkan bahan ajar berbasis konteks dan kreativitas untuk meningkatkan literasi sains siswa Sekolah Dasar. Penelitian ini merupakan penelitian R & D (Penelitian dan Pengembangan) yang meliputi tiga tahap penelitian yaitu: 1) Studi Pendahuluan, 2) Pengembangan bahan ajar, danÂ 3) Uji coba bahan ajar. Studi pendahuluan dilakukan dengan studi kurikulum IPA di SD dan survey lapangan terhadap guru-guru kelas 4 dan 5 SD di kota sukabumi sebanyak 16 orang. Pengembangan model berupa penyusunan bahan ajar serta validasi oleh expert judgement dan peer reviewer. Uji coba terbatas dan uji coba lebih luas bahan ajar. Tanggapan dari guru dilakukan dengan memberikan kuosioner kepada 3 orang guru. Hasil yang diperoleh dari penelitian ini adalah, berdasarkan analisis kurikulum pembelajaran IPA di SD menuntut adanya pembelajaran kontekstual yang terintegrasi dengan praktikum untuk menanamkan konsep/konten yang selaras dengan kemampuan literasi sains, 2) telah dihasilkan 3 buah bahan ajar dengan konteks: a) Kemanakah Perginya Capung?, b) Mengapa Hujan Turun?, c)Â Mengapa gigi kita bisa sakit?. 3) Hasil uji coba terbatas dan lebih luas dijadikan pijakan untuk pengembangan bahan ajar, 4) umumnya guru memberikan respon yang baik terhadap bahan ajar yang telah dikembangkan.

Laboratory activities are important of science learning at any level. At the elementary school lab work needs to be done in the context of daily life in order to training scientific literacy. This study aims to determine how the teacher's perspective on science teaching in primary schools in Sukabumi, West Java in the academic year 2015/2016. Research methods such as survey, data analysis quantitatively and qualitatively. Data collection Â used is a kuosioner sheet and interview guides to explore the teacher's perspective grade 4 and 5 primary school in implementing and understanding the context-based practicum. The results Â showed all the teachers (100%) stated the laboratory activities is important to be implemented, but most of the teachers (75%) stated the laboratory activities difficult to implemented. Teachers argued do not understand the practicum as an activity that can be done simply based on the context of everyday life in an effort to train science literacy (97%). The results of the elementary teacher's perspective is able to provide precise information about the condition of learning science as a material improvement regarding practical learning becomes more meaningful.Â Keywords: practical laboratory, context, Scientific Literacy

Carbon monoxide (CO) contained in cigarette smoke is a very strong poison, if it is smoked by the lungs it will be easier to bind hemoglobin, so that red blood cells will lack oxygen, which can cause damage to blood vessels. with the process of atherosclerosis (narrowing). Sansevieria trifasciata has the ability to absorb poisons such as CO. This study aims to determine the effectiveness of Sansevieria trifasciata leaf extract in absorbing CO contained in cigarette smoke and assessing the amount of CO absorbed by Sansevieria trifasciata leaf extract. The method used is a pure experimental method using a Completely Randomized Design (CRD) consisting of 3 different treatments and 3 repetitions. The results of the 3 treatments showed that P1 (Sanseviera trifasciata wet extract) had the ability to absorb CO an average of 12.67 ppm every 15 minutes, in contrast to P2 (ethanol extract of Sanseviera trifasciata) which absorbs CO. 91.11 ppm every 15 minutes P3 (ethanol extract and CMC leaves from Sansevieria trifasciata) has the ability to absorb CO by 37.89 ppm every 15 minutes. The highest absorption effectiveness was obtained by ethanol extract and bracelets containing ethanol extract with the addition of CMC.

The ability of understanding important concepts held by educators and learners. This ability is fundamental in achieving one of the outcomes of learning. Their understanding of the concept of ownership is the ability of a person can use in solving a problem that is related to the concept in everyday life. This descriptive study aims to obtain a description of the conceptual understanding of prospective biology educator students through the use of peer and self-assessment in class discussions. The research subjects were 26 prospective Biology educator students of the 2019/2020 academic year who contracted the human body anatomy physiology course. The instruments used consisted of peer and self assessment sheets, lecturer observation sheets and conceptual understanding questions. Data analysis was carried out quantitatively and qualitatively. The results showed that the average peer assessment score was greater than the self assessment, where the peer assessment was in the moderate category (49%) and the self assessmet was in the poor category (34%). There were only 10 students (38.46%) who were in conformity between peer and self assessment with adequate and insufficient categories. The discrepancy was found in 16 students (61.54%) with the category enough, less and very less. The ability to understand the concept of students on each indicator shows different percentage mean. The highest percentage of concept understanding ability indicators is found in the indicators of explaining the concept with its own sentence structure about something that is read or heard clearly / concretely by 64% (Good), while the lowest percentage of indicators of concept comprehension ability is found in the indicators able to connect symbolic forms (pictures, tables, concept maps, diagrams, graphs, mathematical equations, and other formulas) in concepts with other concepts of 51% (Enough).
