Abstract

This study aims to determine the effect of tomato paste on blood cholesterol in mice. It was an experimental study using a complete randomized study design consisting of four treatments P0, P1, P2, and P3 by giving tomato paste solution in a concentration of 0%, 20%, 40% and 80% and 6 replications. Data were analyzed using Anova one path and continued with BNT with a confidence level of 95%. The results showed that the tomato paste solution affected the blood cholesterol of mice due to Fhit (3.27) F tab (3.10) and the treatment that gave the greatest effect was on giving the concentration of tomato paste solution by 80%.

Abstract

This study aims to determine the effect of learning model Group Investigation (GI) with the experimental method on cognitive learning outcomes of students. The study population was all students of biology education second semester, Academic Year 2014/2015. The sample in this study was determined by cluster random sampling technique consists of two classes namely class A (treatment) using Group Investigation learning model (GI) and class B (control). Data collection techniques using test techniques to get the data the cognitive learning. This type of research is a quasi experimental study. Design research in this study using a pretest-posttest design. Data analysis techniques in this study using statistical analysis techniques with separated variance t test. Cognitive learning outcomes the average value of class A (treatment) 78.09 70.95 while the control class. Results of t-test showed significant value 0:03 <0:05 so that we can conclude the learning model Group Investigation (GI) effect on the cognitive learning Environmental Science Biology Education Program.

Abstract

Mikroplastik merupakan partikel berbahaya yang dapat masuk ke dalam sistem rantai makanan sehingga dapat berdampak pada kesehatan baik bagi biota air maupun mamalia. Penelitian ini bertujuan untuk mengetahui kandungan mikroplastik pada ikan gabus (Channa striata B) dan ikan baung (Mystus nemurus CV) di Samarinda. Metode pengambilan sampel dengan purposive sampling. Sampel ikan Gabus diambil dari 5 pasar, Sungai Mahakam, dan Waduk Benanga. Sampel ikan baung (Mystus nemurus C.V) diambil di Pasar Ijabah dan daerah aliran Sungai Mahakam. Analisis dilakukan di Laboratorium Kualitas Air Fakultas Perikanan dan Kelautan. Pengumpulan data dengan melarutkan sampel pada NaCl jenuh kemudian diamati dengan mikroskop. Hasil penelitian menunjukkan terdapat jenis fiber, fragmen, monofilamen dengan ukuran 20-350 µm dan didominasi ukuran <150 μm pada sampel ikan. Jika termakan oleh manusia atau mamalia dapat terjadi penyerapan ≤0,3% pada limpa namun masih dapat ditoleransi. Maka perlu tindak lanjut penelitian terkait kadar maksimal terjadinya akumulasi mikroplastik pada manusia.

Abstract

Online learning is extremely common during the Covid-19 pandemic. That sudden alteration, from offline to online learning affect the learning process including the perception of students and teachers using online learning platform. The aims of this study are to determine the students’ perceptions of class XI MIA on online biology learning by using Madrasah E-Learning at MAN Penajam Paser Utara. The data was collected by conducting the observations, interviews and questionnaires. The questionnaire was in Likert scale form that has been valid and reliable (ralpha= 0, 836) with a very strong category. The indicators that were studied include the indicators of student activity, indicators of student perceptions of Madrasah E-Learning and the indicators of factors that affect learning in network (online). Descriptive statistical techniques were the data analysis technique that was used in the form of descriptive, frequency distribution and percentage. The results showed that the activity based on the attendance and collection of student assignments during online biology learning was in the good category. Students' perceptions of Madrasah E-Learning are in very positive category with 63.89%. However, the use of Madrasah E-Learning is still not effective due to network constraints and the lack of teacher skills and knowledge regarding the use of Madrasah E-Learning features. The factors that influence learning in the network include learning support facilities such as cellphones and laptops, network factors and internet quotas, motivational factors, learning interest factors, family factors, home atmosphere factors, environmental factors, and economic factors

Abstract

The low understanding of concepts can be caused because the learning process is not maximized which makes students inactive, unable to think independently, more practical to find answers on the internet, and unable to express what they have learned. Digital School Books as a medium and learning model Survey, Question, Read, Reflection and Review (SQ4R) is an alternative that can activate students and make it easier to remember concepts so that learning is more meaningful. The purpose of this study was to describe the effect of the SQ4R learning model with digital school books on students' understanding of biology concepts in class VII at the Madrasah Tsanawiyah Nurussa'adah Sangkulirang Islamic Boarding School. This research is a quasi-experimental study with a pretest-posttest control group design. The study population was students of class VII, using cluster random sampling technique which produced class VII.B as the experimental class and class VII.A as the control class. The results of the data analysis showed that there was an influence of the SQ4R learning model with digital school books on the understanding of biology concepts for class VII students at the Madrasah Tsanawiyah Nurussa'adah Sangkulirang Islamic Boarding School.
