Abstract

Beberapa jalan raya di Indonesia berada di atas tanah lempung ekspansif. Daya dukung tanah lempung ekspansif sangat dipengaruhi oleh kadar air, sehingga akan memperle-mah perkerasan jalan dalam kondisi jenuh dan akan memiliki kekuatan dalam kondisi kering. Kadar air berpengaruh besar terhadap kembang susut dan parameter kekuatan geser tanah. Pembangunan jalan-jalan yang dibangun di atas tanah lempung lunak se-ring rusak, misalnya jalan akan retak dan bergeombang sebelum umur rencana berakhir. Untuk mengatasi masalah dimana daya dukung dipengaruhi oleh kadar air, ada alternatif yang dapat dilakukan seperti stabilisasi.Penelitian ini bertujuan untuk menganalisis tanah lempung lunak Gading Wonosari 33 km dari Yogyakarta yang dipadatkan 95% γdmaks dengan penambahan polimer lateks 2,5%, 5%, 10% dengan waktu pemeraman 1 hari, dan kemudian melakukan uji triaksial terkon-solidasi undrained (UU), California Bearing Rasio (CBR), uji tekan bebas.    Penelitian ini menghasilkan bahwa tanah diklasifikasikan sebagai CH (berdasarkan klasi-fikasi Unified) dan A-7-6 (berdasarkan klasifikasi AASHTO). Penambahan aditif akan membuat Batas Cair (LL) menjadi turun dengan Plastic Limit (PL) tetap konstan dan mampu menurunkan Indeks Plastisitas(PI). Persentase gradasi butiran membuat fraksi bawah dan gradasi tanah lempung naik. Penambahan aditif bekerja secara efektif di CBR direndam dengan peningkatan nilai CBR dan mengurangi pengembangan tanah. Uji te-kan bebas akan lebih efektif dengan penambahan garam anorganik. Perilaku matrik suc-tion akan meningkat seiring dengan penurunan kadar air. Penelitian ini menyimpulkan bahwa polimer lateks aditif dapat mengisi dan menutupi pori tanah dan membuat kondisi kedap air serta terjadi peningkatan kekuatan tanah ketika menjadi jenuh tanpa peru-bahan karakteristik fisik apapun.

Abstract

One of the cognitive skills that students must have is problem-solving ability. Therefore, a standardized test is needed to measure this ability. However, until now, the tests used to measure mathematical problem-solving ability were not standardized. This research aims to develop a valid and practical mathematical problem-solving test in the discussion of triangles and rectangles. This research is part of the R&D 4D type with steps: Defined (analysis to develop a test), Design (designing a problem-solving test form), and Develop (expert judgment and small group trials). The instrument in this research was the validation sheet used by the validator to assess each test item. The data analysis technique used the Aiken method for expert judgment and qualitative descriptive for development testing. The result is a valid and practical mathematical problem-solving test because the V-Aiken value is more than 0.532. Based on this, the instrument can be used to measure the mathematical problem-solving ability of junior high school students in the discussion of triangles and rectangles.

Abstract

Low problem solving ability will give students a problem. These problems are part of the background of this research. The purpose in this study was to give description about the problem-solving profile in class VIII students on circle material which is based on the differences in mathematical abilities in terms of the Polya stage. Four (4) grade VIII students of MTs N 3 Banjarnegara were the chosen targeted subjects in this research, each of which consisted of students with different categories which are high and medium to low cabilities. The instrument in this study was the researcher, who received assistance using interviews and also some questions on a test for solving a problem in the field of mathematics. The results in this study showed that students who have high abilities able to carry out the calculation steps, but students who had high abilities were more dominant in being able to understand the problem. Students with moderate abilities are more dominant in being able to carry out calculations in the step of planning completion. Meanwhile, low-ability students are able to perform calculation steps, but low-ability students experience a little difficulty in carrying out each of the steps.

Abstract

Problem-based learning in the context of mathematics learning is a math learning strategies in the classroom with activities solve mathematical problems so that students can construct mathematical knowledge by himself. In connection with the efforts to achieve the learning objectives of mathematics through problem-based learning, of course, requires students to use the potential optimally. Meanwhile, to create mathematical learning process with the use of students' potential optimally, then the emotional intelligence of the students need to be a concern. Emotional considerations in mathematics learning in particular may be a bit much help in receiving math, in the middle of contention that still believed by most students, that math is a difficult subject. Thus, the presence of emotional intelligence can be seen as aspects to consider, it can even be used as the basis for follow-problem-based learning process well so that the achievement of mathematics learning in their entirety.
