Abstract

AbstrakTelah dilakukan pengukuran resistivitas dan dielektrisitas tanah perkebunan Apel di Malang. Pengukuran resistivitas dilakukan dengan metode Geolistrik dan dielektrisitas dengan menggunakan Ground Penetrating Radar (GPR). Metode Geolistrik dilakukan dengan konfigurasi dipole-dipole dengan teknik sounding –mapping pada tiga lintasan area perkebunan seluas 1800 m2 dan satu lintasan pada area lapangan di sebelah perkebunan. Sementara itu, metode GPR diterapkan pada dua pohon apel untuk mengidentifikasi sistem perakaran apel. Pengukuran resistivitas dilakukan di perkebunan Apel desa Bengkaras Pujon, Malang sedangkan GPR dilakukan di perkebunan Poncokusumo Malang. Dari hasil pengolahan data resistivitas dengan menggunakan software Res2dinv diperoleh hasil nilai resistivitas dari keempat lintasan adalah: lintasan pertama 4,83 – 22094 Wm, lintasan kedua 6,69 – 4947 Wm, lintasan ketiga 14,1 – 178 Wm dan lintasan keempat 4,50 – 20025 Wm. Dari data tersebut secara keseluruhan belum dapat dibedakan dengan jelas nilai resistivitas antara daerah perkebunan dengan bukan perkebunan di lingkungan penelitian. Sementara itu dari pengukuran GPR diperoleh jangkauan pengukuran mencapai kedalaman 2,18 meter dan jangkauan kedalaman akar apel 1.9 meter. Rentang nilai konstanta dielektrik yang diperoleh 0,1 – 8,8 F/m. Nilai konstanta dielektrik akar 4,9 F/m. Kata kunci: Resistivitas, dielektrisitas, tanah, perkebunan apel AbstractThe resistivity and dielectric properties of Apple’s soil plantation area in Malang have been measured.  Resistivity measurement was done using geo-electrical methods and dielectric properties was measured using ground penetrating radar (GPR).

Abstract

Research that uses the Schlumberger configuration resistivity method had been conducted in Cangar. The purpose of this study is to identify cracks/faults and potential hot springs use resistivity well analysis and correlate it with rock lithology in Cangar, East Java. Data acquisition is carried out using 3 tracks with 10 sounding points. The space between points is 50 meters. The rock resistivity values obtained were 9945 Ωm, 7360 Ωm, and 5573 Ωm which were thought to be breccia layers and functioned as hot springs. This estimation is strengthened by the existence of a layer of breccia-andesite because this layer is very good as a water reservoir. In addition, based on the lateral cross-section on lane 1, there was a decrease in boulder-sized breccia-andesite layers; this decrease was the production of faults.

Abstract

The image of subsurface with a migration method keeps on developing to get an image result which the closest in real condition. The conditions in subsurface are very complex and variables it couses the process of wave  propagation which can not be judged as the same in every layers. so it is needed an anisotropy pharameter analysiz (η) in seismic data migration process. The research will compare two kinds of migrations those are Kirchhoff migration and finite difference anisotropy. It is done because not all datas are processed by anisotropy, even with isotropi it will get good result. The result of kirchoff migration has not so good quality (low resolution) on the first layer reflector.but on the second and third layer reflector have good result (high resolution). I estimate that in the first layer reflector there is anistropi influence, because the ratio effect between far offset and the depth is hight. The analysis result get η ansotropi pharameter result as 0,25 and put into migration process. On the second migration process is finite difference anisotropy appears on the first layer reflector and shows high resolution and suitable with the real layer model.

Abstract

This study aims to describe students’ problem-solving abilities and percentages in solving science (physics) problems in Work materials and simple aircraft class VIII MTsN 2 Trenggalek. This research uses a qualitative approach with a descriptive type of research. The data collection techniques used are tests and interviews. The data analysis includes 3 stages: data reduction, data presentation, and conclusion. The results of the research on students’ problem-solving ability are based on the stages of the Polya model: (1) High-ability students have been able to meet all indicators of the Polya problem-solving stages by 82.99% in the very high category. (2) Moderately capable students can already meet all indicators of the problem-solving stages for Work questions. However, they are still less capable in simple aircraft questions, with a percentage of 64.58% being in the high category. (3) Low-ability students have not been able to meet all the indicators of the problem-solving stage, with 15.42% being in the deficient category. Students cannot understand problems, draw plans, execute plans, and look back. The reason is that students do not understand the material clearly, which impacts their problem-solving ability. The research showed that students’ problem-solving ability is in a suitable category with a percentage of 54.33%. The stage of understanding the problem includes the stages the student can achieve. Students are still underprivileged in the following three stages: drawing up a plan, implementing a plan, and looking back. Students still have difficulty determining the right strategy to solve problems in Work and simple aircraft questions.
