Abstract

This study aims to improve the students' abilities through the application of an environmentally-based guided inquiry learning model in grade IV SDN INPRES Kabonena and the student learning outcomes in science learning through the application of environmentally-based guided inquiry learning models in grade IV SDN INPRES Kabonena. This type of research is a classroom action research, using a spiral model design of Steven Mc. Taggart, which consists of 4 stages, namely planning, implementing, observing, and reflecting. The location of the research was at SDN INPRES Kabonena, Palu City. The research subjects were 20 students, consisting of 11 male students and 9 female students. The data consists of learning data including data on teacher skills and student activities. Data collection techniques are by observation and tests. Data analysis was performed by qualitative data analysis by concluding based on the mean value or standard deviation of observations (percentage of observations). The results showed that the students' ability in learning through the observation of teacher skills in the first cycle obtained a score of 22 with a good category percentage of 61%, and in the second cycle a score of 29 was obtained with a percentage of 81%, very good criteria. The ability of students in learning based on student activities in teaching and learning activities, in the first cycle a score of 21 was obtained, with a percentage of 58% in the sufficient category, and in the second cycle, it was obtained 27.5 with a percentage of 76.4% in the good category. Meanwhile, the student ability data obtained for pre-action, the number of students who completed as many as 5 students, with classical absorption (DSK) 50% and classical learning completeness (KBK) 25%. The data on student ability in the first cycle obtained 6 students with a DSK of 57% and a CBC of 30%, an increase in the second cycle where the number of students who completed 20 students with 88% DSK and 100% CBC While the data on student learning outcomes in the first cycle obtained 8 students with a DSK of 59% and a CBC of 40%, an increase in cycle II where the number of students who completed was 20 students, with a DSK of 87% and CBC 100%. Based on these results, it can be stated that the application of an environment-based guided inquiry learning model can improve problem-solving abilities and learning outcomes of fourth-grade students of SDN INPRES Kabonena.

Abstract

Flora information of bryophyte in Sulawesi were limited found. Research on the bryophyte diversity at the different elevation of Mount Rore Kautimbu Lore Lindu National Park (LLNP) Central Sulawesi which had conducted from December 2013 to February 2014 was an effort to completed data and information of Bryophyte in Sulawesi. Bryophytes were sampled in three forest type s.a Sub-Montane Forest (1448 masl), Montane (2022 masl) and Alpine (2518 masl). In each zone was placed the plot size is 20 x 20 m sub-plots with measuring 1 x 1 m to substrate rocks, soil, decayed wood and plots 10 x 30 cm on the substrate of the tree. Data were analyzed by calculating the value of frequency, density, an important value index and the index of diversity according to the Shannon-Wiener. Research results gained as much as 41 species consists of 21 species mosses and 20 species of liverworts, which was dominated by the family dicranaceae. Based on the type of diversity Indices according to the Shannon-Wiener diversity was found in the highest zone of bryophytes and Alpine zones (H ' = 2.79) followed by Montane zone (H ' = 2,52) and Sub-Montane zone (H ' = 2.20).   Keywords:Bryophyta, Diversity, elevation, LLNP

Abstract

ABSTRAK   Penelitian ini bertujuan untuk mengetahui hubungan kandungan Pb di udara dengan Pb dalam talus lichen X.  xanthofarinosa. Penelitian dilakukan di kota Malang. Hipotesis yang diajukan terdapat hubungan kandungan Pb di udara dengan Pb dalam X. xanthofarinosa. Lichen X. xanthofarinosa diambil dari 20 lokasi yang tersebar di kota Malang. Kandungan Pb dalam X. xanthofarinosa dianalisis dengan metode Atomic Absorption Spectrophotometer (ASS). Sedangkan kandungan Pb di udara diukur dengan menggunakan alat High Volume Air Sampler (HVAS). Data tentang hubungan kandungan Pb di udara dengan Pb dalam X. xanthofarinosa dianalisis dengan regresi. Hasil penelitian menyebutkan bahwa pada Standardized Coefisients (Beta) memiliki nilai 0,657, hal ini  menunjukkan bentuk hubungan positif dan tingkat korelasi antara Pb di udara dengan Pb dalam X. Xanthofarinosa. Nilai t = 3,702 dengan tingkat signifikansi 0,002. Karena 0,002 < 0,05, maka hipotesis statistik (Ho) ditolak, dengan demikian hipotesis penelitian diterima. Sehingga dapat disimpulkan bahwa terdapat hubungan yang positif  antara kandungan Pb di udara dengan Pb di dalam talus lichen X. Xanthofarinosa.   Kata kunci : Pb, Udara, dan  X. Xanthofarinosa

Abstract

The research method uses the Hopkins model design which consists of 4 stages, namely planning, implementation, observation and reflection. Data collection techniques using observation and test methods. The results showed that the percentage of student activity in cycle I was 69% (enough), increased in cycle II to 88% (very good), the percentage of teacher activity in cycle I was 72% (enough), increased in cycle II to 91% (very good). Good). Likewise with the assessment of student learning outcomes; the percentage of attitude evaluation in cycle I was 87% increased in cycle II to 90%, evaluation of the realm of knowledge in cycle I for Classical absorption (CA) 74% and Classical Learning Mastery (KKB) 83% increased in cycle II to Classical absorption (CA) 80% and Classical Learning Mastery (PKK) 93%, the assessment of the domain of skills in cycle I was 69% increased in cycle II to 94%.

Abstract

Low metacognitive abilities and high-level thinking cause students to have difficulty understanding genetics course material. This research aims to analyze the effectiveness of PBLRQA, PBL, and RQA strategies on students' metacognitive and higher-order thinking skills. This research uses a non-equivalent control group pretest-posttest design. Sampling was carried out on 118 students consisting of four classes using saturated sampling techniques. The research instruments used were observation sheets on lecturer and student activities, essay-based metacognitive skills tests, and multiple-choice tests on high-level thinking skills. Lecturer and student activity data were analyzed based on the percentage of indicators categorized as high and very high syntactically. Data on metacognitive skills and higher-order thinking were analyzed using the Normalized Gain and Independent Kruskal Wallis tests. Research findings show that implementing PBLRQA, PBL, and RQA strategies is ineffective in improving students' metacognitive and higher-order thinking skills. To follow up on these findings, further research is needed to explore the involvement of learning styles and social support on students' metacognitive skills and higher-order thinking skills, focusing on implementing PBLRQA and RQA strategies.

Abstract

The Islamic conception of knowledge does not limit knowledge about reality to that obtained through experimentation and theoretical reasoning only. Natural knowledge that is understood does not just answer human desires if we can accommodate revelation and intuition, including the spiritual and physical aspects of humans and the cosmos. Understanding the integration of Islamic values ​​in natural science (science) learning is implied in the Qur'an. The Koran does not conflict between science and religion. In fact, in many of His verses it is emphasized that humans should always think about events in nature to strengthen their religious beliefs. Science in this case is also not a separate part of religion. Science is an integral part of the Islamic religion. The Koran states that science, like the science of human life, is an integral part of religion. Science teaches humans how to manage nature, carry out various processes, and produce things for life's needs. Meanwhile, religion teaches humans about value systems. Religion teaches the value of piety towards the Khaliq and the value of kindness towards others.
