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

This study aims to describe the effect of the application of modules in science learning on the learning outcomes of seventh grade students at SMP Negeri 3 Mepanga. This type of research is a quasi-experimental by forming two groups of research subjects, namely the experimental group using learning modules and the control group using student books in the learning process. The research design used was unreated control group design with dependent pretest and posttest samples. The results of this study indicate that there are differences in the average learning outcomes of experimental group students and control group students. The average experimental group student learning outcome of 79.54 and the average value of control group student learning outcomes is 73.04. This is evidenced by the value of Sig. (2-tailed) on a t-test smaller than 0.05, Sig. (2-tailed) 0.001 <0.05, thus H0 is rejected and Ha is accepted, which means that there is an effect of application of modules in science learning on the learning outcomes of seventh grade students at SMP Negeri 3 Mepanga.

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.
