PROFIL BERPIKIR ALJABAR SISWA SMP DALAM MENYELESAIKAN MASALAH MATEMATIKA DITINJAU DARI GAYA KOGNITIF (REFLEKTIF DAN IMPULSIF)
Full text linkAbstract: The purpose of this study is to describe the profile of algebraic thinking in junior high school students in solving mathematical problems in terms of cognitive style (reflective and impulsive). The subjects used were class VIII B Arjasa 1 Junior High School as many as 25 children. Data collection in this study used two test questions, namely the MFFT test (Matching Familiar Figure Test), algebra test and interviews with four students representing different cognitive styles (reflective and impulsive) . In this study students who have reflective cognitive style and students who have impulsive cognitive style can fulfill five indicators of algebraic thinking, namely generalization, abstraction, analytical thinking, dynamic thinking, and modeling.

MENINGKATKAN HASIL BELAJAR LISTRIK DINAMIS MELALUI MODEL TGT DENGAN PERMAINAN CERDAS CERMAT
Full text linkAbstract: The aim of the research is to describe the implemenation of the use TGT model by applying Cerdas Cermat (Smart and Precise) Quiz to Increase the IXE SMP Negeri Sukorambi students’ learning achievement on dynamic electricity in the 2017/2018 Academic Year. Classroom Action Research was Designed by applying TGT Learning Model in Cerdas Cermat Quiz. The research steps was conducted by making small group the students at the beginning. Then, group discussion, presentation of group discussion result, and answering problems exercise. The result of Grade IXE SMPN Sukorambi science daily examination was still low, it was around 30%. It was probably because of the weakness of learning activity which was caused by uninteresting teaching model.

ANALISIS PEMANFAATAN MULTIMEDIA TERHADAP PENGUASAAN KONSEP REAKSI NUKLIR MAHASISWA PADA MATAKULIAH FISIKA INTI
Full text linkOne of the uses of multimedia is to explain abstract concepts that cannot be directly observed by the five senses to be more easily understood, especially related to the concept of nuclear reactions in nuclear physics courses. This research aimed to get an overview of the mastery of the concept of nuclear reactions in students who take core physics courses and get an overview of the responses of students' perceptions of learning. The method of this research was experimental research with one group pretest-posttest design. Data collection techniques used in this research include the mastery test, student response questionnaire, documentation and observation. Data analysis techniques include descriptive analysis of student response questionnaires about multimedia-assisted nuclear physics learning process and analysis of mastery test results of the concept of nuclear reactions in nuclear physics courses using Ngain scores. The results showed that there was an increase in mastery of the nuclear reaction concept in nuclear physics subject with score of n-gain result was 0.41 and came into medium category. The ability to master concepts includes the ability to remember, understand, apply, analyze and evaluate. Based on this description, it can be concluded that the use of multimedia can increase students’ mastery concepts of nuclear reactions concept in nuclear physics courses
IDENTIFIKASI GEOMETRI BIDANG PADA POLA MOTIF KAIN TENUN SOLOK BANYUWANGI
Full text linkA culture is born from the local community so as to produce works that become the characteristic of the culture. This culture is rooted and develops over time. One result of cultural work is Banyuwangi solok weaving. Education appreciates local culture in order to participate in preserving through the teaching and learning process. Weaving Solok Banyuwangi can be included as a medium for student learning in schools. Mathematics is one branch of science that studies symbols with logical reasoning. So there are estimates of the mathematical elements found in the Banyuwangi solok weaving motif. Mathematical elements found in Banyuwangi solok weaving include points, lines, triangles, quadrilaterals, hexagon, folding symmetry, rotary symmetry, congruence and similarity.

PENERAPAN MODEL PEMBELAJARAN MATEMATIKA REALISTIK UNTUK MENINGKATKAN AKTIVITAS DAN HASIL BELAJAR
Full text linkAbstract: This study aims to improve the quality of education by making changes towards improvements to students' mathematics learning activities and outcomes by applying the Realistic Mathematics Learning model. This research was conducted in class X SMA Negeri Rambipuji in the even semester from April 19 to May 17 2016, with 32 students. This research is a classroom action research (PTK) which consists of 2 cycles with 4 stages, namely planning, implementing, observing and reflecting. Activity data were collected through observation at each lesson and learning outcomes were obtained through tests at the end of each cycle. Based on the data analysis, it was found that student activity increased the percentage of cycle I and cycle II, namely 68% and 82%. Meanwhile, the learning outcomes increased by 61% and 89%. From the results of this study, it can be concluded that the application of a realistic mathematics learning model can increase the activity and learning outcomes of class X SMA Negeri Rambipuji on the subject of cubes and blocks for the 2017/2018 academic year.

Full text linkAbstract: Avocado leaves (Persea americana Mill.) historically used as a herbal medicine used to ease the expense of urine and crushed a kidney stone in the urinary tract. Avocado leaves contain sugar, d-parseit, quercetin, flavonoids, and compounds sterin. The availability of avocado leaves in the society becames a great opportunity to be utilized as a herbal medicine, it is unknown yet whether the avocado leaves extract was able to decrease edema glomerulus and cell damage in the kidneys. The aim of this research knew the effect of ethanol extract of avocado leaves to decrease edema glomerulus and cell damage kidney of white rat. The research method used The Post Test Only Control Group Design. The dose was 100 mg/0.2kg bw, 200 mg/0.2kg bw, 300 mg/0.2kg bw, with inducer (ethylene glycol + ammonium chloride) as positive control, the treatment carried out during 10 days. Data analysis used Anova. The results showed for parameter damage the glomerulus with (F = 4.931, p = 0.027, < 0.05) which means there was the effect of the ethanol extracts of avocado leaves significantly to decrease edema glomerulus, while parameters proximal tubule damage with (F = 5.755, p = 0.018, < 0.05) which means there was the effect of the ethanol extracts of avocado leaves significantly to decrease cell damage kidney white rat. The dose of ethanol extract of avocado leaves which are most effective against the decrease of edema glomerulus was 100 mg/0.2kg bw and cell damage kidney white rat was 200 mg/0.2kg bw.
