UPAYA MENINGKATKAN TANGGUNG JAWAB PESERTA DIDIK PADA PEMBELAJARAN MATEMATIKA MELALUI MODEL KOOPERATIF TIPE JIGSAW DI KELAS VIII A SMP N 2 LENDAH TAHUN PELAJARAN 2018/2019
Full text linkThe objective of this study was to improve students’ responsibility especially in math class with Jigsaw cooperative learning and to know the implementation of Jigsaw in math class. This study was a collaboration classroom action research. Kemmis & Mc. The Taggart model was used in this study. The subject of this study was students in eighth grade in SMP N 2 Lendah. The result of this study showed that there is an improvement in students’ responsibility in math class by using Jigsaw. Students played a role as an expert and they discussed specific topics. After that, they discussed again in a big group and shared what they got in a small group. There is 2 cycle because in the second cycle has achieved this study target. In last, there are no students who have low responsibility or below. Almost 70% of students have high responsibility and the rest have average responsibility
Analisis Analisis Berpikir Kritis Siswa SMP dalam Menyelesaikan Soal Pecahan ditinjau dari Gaya Belajar
No full textIn learning activities, one of the efforts that can be done to improve students' learning abilities is to support learning styles that are following the objectives so that learning can be done effectively. This research was conducted at Junior High School 1 Kalisat, located at Jl. Diponegoro 52 Kalisat, Jember. This study aims to describe the students' critical thinking processes in solving fraction problems in terms of visual, auditory and kinesthetic learning styles. Data collection techniques used consisted of learning style questionnaires, critical thinking tests, and interview method. The subjects in this study were 6 students consisting of 2 students who represented visual, auditory, and kinesthetic learning styles. Based on data analysis, the results show that students with a visual and kinesthetic learning style meet five indicators of critical thinking, namely basic clarification, basic skills, concluding, further clarification, and strategies and tactics. Students with auditory learning styles meet the four indicators of critical thinking namely basic clarification, building basic skills, further clarification, and concluding. While students with auditory learning styles are less able to meet the indicators of strategies and tactics.

PEMODELAN MATEMATIKA ALIRAN DARAH PADA PEMBULUH DARAH ARTERI DAN VENA PADA KELAINAN JANTUNG SINGLE VENTRICLE
Full text linkSingle ventricle is a heart defect in which one of the ventricle does not developed and bother the blood flow. One of the solutions is fontan surgery. The result of Fontan surgery allows the blood flowing in veins that initially lead to the heart change into the arteries. Because of these changes, there are possibility of swelling and velocity change of blood flowing. This research constructed a mathematical model of blood flowing velocity in arteries and veins due to a single ventricle heart defect that was formed from the momentum and mass equation, which was influenced by the diameter of venous vessel and blood viscosity. The analysis of the blood flow velocity in arteries and veins due to single ventricle heart defect was simulated by MATLAB and FLUENT software. The factors observed were the effect of venous diameter and blood viscosity on the velocity of blood flow in the veins. The result indicated that the greater diameter of the vein, the smaller the flow velocity in the vein. The greater blood viscosity resulted the smaller flow velocity in arteries and veins

Students at the informal deduction level have visual skills, logic skills, and applied skills. Female students who are at the analysis level have visual skills, verbal skills, logic skills, and applied skills. Male students at the analysis level have visual skills. Students at the visualization level have visual skills
LEVEL LITERASI MATEMATIKA SISWA DALAM MENYELESAIKAN SOAL PISA KONTEN CHANGE AND RELATIONSHIP BERDASARKAN GAYA KOGNITIF
Full text linkThis study aims to describe the mathematical literacy of field-dependent (FD) students and field-independent students (FI) in solving PISA questions on Change and Relationship content in terms of the achievement of mathematical literacy levels. The PISA issue of Change and Relationship content is related to curriculum material, namely functions and algebra. This research is a qualitative descriptive study. The subjects in this study were students of class X MIPA 6 of SMA Negeri 1 Jember with 29 students consisting of 6 field-dependent (FD) students and 23 field-independent (FI) students. The results showed that the level of mathematics dependent literacy of field-dependent students was at level 2 (66.67% or as many as 4 students) and level 5 (33.33% or as many as 2 students) and the level of mathematics literacy of independent field students was at level 2 (13 % or as many as 3 students), level 5 (69.56% or as many as 16 students) and level 6 (17.4% or as many as 4 students)
PEMODELAN MATEMATIKA PADA PROSES PEMBEKUAN ES DI RUANG BRINE TANK PABRIK ES BALOK TALANGSARI JEMBER
Full text linkOne of the main activities of block ice production is the process of freezing ice blocks in the brine tank. Brine Tank is a tank that functions to freeze ice blocks. Brine Tank contains salt water. Mathematical modeling is a formulation of mathematical models that describe how to get a solution to a mathematical problem in a natural event. Mathematical modeling can form mathematical models that describe the process of ice freezing in brine tanks in accordance with actual conditions without ignoring important factors in the system. The mathematical model in the process of ice freezing in the Brine Tank is obtained from the momentum equation and the energy equation which is solved using the finite volume method. In this study a mathematical model was built to determine the effectiveness of time in the ice freezing process in the brane tank

PROSES BERPIKIR KREATIF SISWA TUNANETRA DALAM MENGKONSTRUK BANGUN DATAR BERBANTUAN ALAT PERAGA TANGRAM MENURUT TAHAPAN WALLAS
Full text linkThis study aims to describe the creative thinking process of blind students in constructing plane figure assisted by tangram props according to the stages of Wallas. The research subjects were three blind students of VIII grade SLB-TPA Negeri 1 Branjangan. Data collection methods used were test questions constructing plane figure and interviews. Based on the analysis of the results of tests and interviews shows that students of S1, S2, S3 through all the processes of creative thinking according to the Wallas’s stages include the preparation stage, the incubation stage, the illumination stage, and the verification stage when resolving problems constructing plane figure. At the preparation stage, blind students tend to lack understanding of the initial information such as explaining the problem given. At the incubation stage, blind students need a long time to do the process of pondering thinking about solving the problem in question. At the illumination stage, blind students are able to get two or more different ideas for completion. Blind students tend to use trial and error to find an idea. At the verification stage, blind students tend to re-check the answers obtained to reassure the answers are correct

Full text linkThis study aims to analyze the stages of creative thinking of students with choleric personality types in solving Algebra problems. This type of research is qualitative research. Students with choleric personality types are given Algebra questions followed by interviews to explore information in students' creative thinking processes. The results obtained are students capable to form a mathematical model of the information contained in the problem using the Algebra symbol at the preparation stage. Students are capable to find more than one settlement idea by utilizing the equations formed in the problem and require a short time to understand the problem at the incubation stage. Students are capable to write the completion steps containing Algebra operations systematically at the illumination stage. Students are capable to recheck the answers generated by substitute the value of the variable sought into an equation well at the illumination stage. The conclusion of this study is that choleric students are capable to fulfill all the indicators at the Wallas creative thinking stage. This can be seen from the results of the Algebra test given and the results of the interviews that have been conducted
