Full text linkProfil pemecahan masalah merupakan gambaran secara umum mengenai kegiatan memecahkan masalah matematika yang dilakukan oleh siswa dengan menggunakan lima tahapan pemecahan masalah model IDEAL, yaitu mengidentifikasi masalah, mendefinisikan masalah, mencari solusi, melaksanakan strategi, dan mengkaji kembali serta mengevaluasi pengaruhnya. Hal tersebut menjadi menarik ketika dikaitkan dengan kemampuan matematika. Penelitian ini bertujuan untuk mendeskripsikan profil siswa berkemampuan matematika tinggi dalam memecahkan soal cerita pokok bahasan Aritmatika Sosial. Jenis penelitian ini adalah penelitian kualitatif. Siswa berkemampuan matematika tinggi diberi dua soal tes pemecahan masalah, kemudian dilakukan wawancara untuk mengetahui lebih dalam proses dalam memecahkannya. Hasil yang diperoleh adalah siswa berkemampuan matematika tinggi mampu memenuhi semua indikator dari setiap tahap pemecahan model IDEAL. Hal ini terlihat dari hasil pekerjaan yang diberikan dan wawancara yang dilakukan oleh peneliti terhadap siswa tersebut
PENGARUH MODEL PEMBELAJARAN SFE (STUDENT FACILITATOR AND EXPLAINING) BERBASIS BBL (BRAIN-BASED LEARNING) TERHADAP HASIL BELAJAR DAN RETENSI SISWA: MODEL PEMBELAJARAN SFE (STUDENT FACILITATOR AND EXPLAINING) BERBASIS BBL (BRAIN-BASED LEARNING)
Full text linkEducational problems that exist in the classroom in general, namely the learning process is still dominated by teacher-centered learning and theoretical resulting in low retention and student learning outcomes. One way to improve student retention and learning outcomes requires a revolutionary paradigm by a teacher in the learning process. The BBL (Brain-Based Learning) based SFE (Student Facilitator and Explaining) learning model can improve student achievment and retention. The purpose of this study was to determine the effect of BBL (Brain-Based Learning) SFE (Student Facilitator and Explaining) learning models on student achievment and retention. This type of research was a quasi experimental. Based on the results of the analysis does not significantly influence the student cognitive (p = 0.134), influencing the student psychomotor (p = 0.006), significantly influence the student affective (p = 0,000), and significantly influence the student retention (p = 0,000)
PENERAPAN MODEL (TSTS) DALAM MENINGKATKAN HASIL BELAJAR IPA SISWA KELAS 9A DALAM MATERI RANGKAIAN LISTRIK DI SMP NEGERI PAKUSARI JEMBER TAHUN PELAJARAN 2019/2020
Full text linkAbstract: This research is motivated by the low participation of students or students' learning activities in the process of learning science class 9A in SMP Pakusari. Proses learning usually undertaken using direct instructional model that is delivering the materials to students as a whole and interspersed with exercises, learning like this causing students to tend to only acquire cognitive knowledge, not yet meaningful learning. This study is a Classroom Action Research (PTK) that uses the model and design of the Kemiss and Mc Taggart spirals. This study was conducted in 2 cycles implemented in the period from September to October 2019. Each cycle consisted of 4 stages, from the planning phase (planning), implementation, observation (observing) and reflection (reflecting). The data collection instruments in this study are student learning activity sheets, field notes and documentation in the form of photographs during the learning process. The results show an increase in student learning activities by using the two stay two stray model, namely speaking activities, writing activities and motor activities increased from cycle I with an average of 81.67 and cycle II with 85.00 final conclusion of this study that the application of learning model cooperative type two stay two stray can increase student learning activities.

PEMBELAJARAN KOOPERATIF DENGAN STRATEGI â€KARMIN ALJABAR†MENRAMPILKAN OPERASI HITUNG ALJABAR
Full text linkAbstract: The implementation of learning is expected to be active, innovative, creative, and fun without leaving the learning concepts. Calculating algebra is a very important learning and many students have difficulty. From the researcher's experience, learning algebra by utilizing the algebra domino card has an impact on students' interest in learning but learning outcomes don’t meet the completeness standards. Researchers strive for more interesting learning by giving deeper concepts in the learning process through cooperative learning with a contextual approach assisted by an Algebra Domino Card, which called "KARMIN Algebra". Based on the results for two cycles, it shows an increase, in cycle 1 obtained 72% of students reaching Minimum Standard Learning (MSL), while in cycle 2 obtained 84%. Meanwhile, the psychomotor and affective, shown that students are more skilled in calculating algebra. Referring to these results, the researchers suggest that this kind of learning can be used as an alternative to learning mathematics in schools by adjusting existing conditions.

PENGARUH MODEL COLLABORATIVE CREATIVITY (CC) TERHADAP KEMAMPUAN LITERASI SAINS DAN HASIL BELAJAR FISIKA SISWA DI SMA
Full text linkAbstract: Education can be used as a benchmark for how good the quality of a country is. Good and good education starts from a good and systematic learning system. The previous 2013 curriculum objectives show that students are required to think higher in terms of the relationship between science and the surrounding environment. One of the abilities in accordance with the 2013 curriculum is scientific literacy skills. the advancement of the era resulted in the increasing competitiveness of the nation when it entered the ASEAN Economic Community (MEA) which enabled the existence of scientific work products accompanied by scientific literacy abilities which were made as obligations to be studied in this century. 1. Collaborative Creativity learning model has a significant effect on scientific literacy skills and learning outcomes in class X material in straight-line material Rambipuji Public High School.

PENGEMBANGAN MODEL PEMBELAJARAN KOLABORATIF SEND A-PROBLEM BERBASIS BBL UNTUK PEMBELAJARAN IPA SMP DI WILAYAH AGROEKOSISTEM
Full text linkStudents in the agroecosystem area have self-motivation to follow low learning which causes their learning outcomes lower. It can be increased by applying Brain-Based Learning (BBL) approach combined with Send A-Problem (SAP) collaborative learning model. This is a development research using 4-D model. Only 3 stages were chosen; define, design, and develop. The research aims to produce a valid, practical and effective SAP based on BBL to increase students' metacognitive awareness and learning outcomes. The average of product validation is 88 (very valid category). The average percentage of students' metacognitive awareness was 66.31 (developing category) before the application and 85.85 (very good category) after the application of the learning. Normalized gain analysis result is 0.62 referred to medium category, which means that there is an increase in student learning outcomes. The average percentage of student (84.33%) and teacher responses (98%) is included in the very practical category

IDENTIFICATION OF SOIL MESOFAUNA IN THE ARABICA COFFEE PLANT AREA: IN KALIBENDO PLANTATION, BANYUWANGI
No full textOne of bio-indicator soil fertility is soil mesofauna. Soil mesofauna is soil organism that have an important role in distributing organic matter in the soil, improving soil physical properties, and increasing soil fertility. If there are more mesofauna in an area of land, the ecological conditions of the land have abundant organic material and have good soil conditions. The purpose of this study was to determine the types of mesofauna found in the soil around Arabica coffee plants. The method for capturing soil mesofauna was with a pitfall trap. The results of the identification of soil mesofauna in Arabica coffee plants on Kalibendo plantations were obtained by several species including the Order of Collembola and Subclass of Acarina. Species of the Order of Collembola was found Pseudoparonella sp., Salina celebensis, Isotomurus balteatus, Lobella sp., Hypogastrura purpurescens, and Sminthurides sp. Whereas from the subclass of Acarina was found the family of Ixodidae
