Abstract

The simulation of the wave propagation of the radar in the sub-surface was very important to be understood before being carried out of field acquisition,to maximize the design of the acquisition and to optimized radar gram data’s.One of the approaches in the simulation of the data was to use propagationmodeling of the electromagnetic wave by using the Finite Difference TimeDomain solution (FDTD). Modeling of electromagnetic wave propagation in theGPR requires a solution of Maxwell’s equations or present a finite-differencetime-domain (FDTD) solution of Maxwell’s that permit accurate computation ofthe radiated field from a transmitting antenna. Propagating through the air-earthinterface, scattering by subsurface targets and reception of the scattered fieldsby receiving antenna. This technique is second-order accurate in time andfourth-order accurate in space. In this paper, I demonstrate the synthetic radargram by applying this technique to two-dimensional examples from a subsurfaceof stratified media.

Abstract

Abstrak: Tujuan dari penelitian ini adalah untuk meningkatkan hasil belajar koginitif matematika kelas IV yang merupakan sekolah berprestasi namun memiliki hasil belajar yang masih dirasa kurang memuaskan. Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas dan dilaksanakan sebanyak 2 siklus. Model pembelajaran yang digunakan dalam penelitian ini adalah cooperative learning. Instrumen yang digunakan dalam penelitian ini adalah lembar tes formatif, lembar observasi, wawancara, dan dokumentasi. Pada pelaksanaan tindakan siklus I terjadi perubahan peningkatan hasil belajar kognitif setelah dilaksanakan tindakan pada siklus II. Jadi dapat disimpulkan bahwa dengan pembelajaran model cooperative learning dapat meningkatkan hasil belajar kognitif matematika.  Kata kunci: Hasil belajar, Matematika, Cooperative learning.    Abstract: The purpose of this research is to the improve of cognitive learning results of fourth grade mathematics which is the achievement school but have learning result that is still felt less of satisfactory. The type of research which used is Classroom Action Research and implemented as much as 2 cycles. The research learning model used in this research is cooperative learning. Instruments used in this study are formative test sheets, observation sheets, interviews, and documentation. In the implementation of the first cycle, there is a change in the improvement of cognitive learning outcomes after the actions in cycle II. So it can be concluded that learning by cooperative learning model can improve cognitive learning results of mathematics. Keywords: learning results, mathematics, cooperative learning.

Abstract

Studi literatur untuk mengestimasi temperature reservoir Gunung Lumpur Bledug Kuwu telah dilakukan menggunakan metode geotermometri larutan. Perhitungan temperature diperoleh dari hasil perhitungan empiris kandungan unsure-unsur kimia terlarut pada air panas Gunung Lumpur Bledug Kuwu. Kandungan unsure ini diperoleh dari hasil analisis sampel air panas dengan metode Atomic Absorption Spectrophotometer (AAS) yang dilakukan oleh Rizqiya 2014, berupa konsentrasi Na, K, Ca, Mg dan SiO2. Dari hasil perhitungan ini, estimasi temperature reservoir Bledug Kuwu berkisar antara 90.411 – 148.354 0C.

Abstract

This study aims to (1) develop mobile learning as mathematics learning media; (2) test the practicality of the developed mathematics mobile learning media; and (3) test the effectiveness of mathematics mobile learning media that is developed towards the autonomous and learning outcomes of elementary school students. This type of research is research and development by adapting the ADDIE model. Product assessment is carried out by media experts, material experts, information technology experts, peer reviewers and trial. The research data was collected through a media assessment questionnaire and tests, then analysed with N-Gain and t-test. The results of this study are: (1) mathematics mobile learning media has been well structured by getting input from media expert validators, material experts, information technology experts, peer reviewers and students; (2) mathematics mobile learning media is considered feasible to be used in learning, in terms of material aspects, media aspects and students' test results, and (3) there is a significant increase between the autonomous and learning outcomes of students who take learning using mathematics mobile learning media with conventional learning. The results of this study indicate that the mathematics mobile learning media is feasible and effective to be used in elementary mathematics learning.

Abstract

Shallot is an important vegetable commodity because it contains high nutrition, raw materials for medicines, as a complement to cooking spices, has lots of vitamins, and acts as an activator of enzymes in the body Average consumption of shallots per capita for 2011-2012 ranging between 2.36 kg / year and 2.74 kg / year. Development of shallot harvest, production and productivity in 2010-2017. Increasing the quality and yield of shallots in several constraints needs to be considered, among others, the provision of nutrients for plants through fertilization. The purpose of this study was to determine the interaction effects of Kusuma BioPlus compost treatment and KNO3 White fertilizer on growth and production of Thai Onion (Allium ascalonicum L.) varieties. This research was conducted in May 2016 until July 2016 in Kediri Begendul Hamlet, Sidowarek Village, Plemahan Subdistrict. Place height 1000 asl, soil pH 6, Type of sandy clay soil. The results showed that there was no real interaction between the dosage of Kusuma Bioplus fertilizer and KNO3 fertilizer on the number of leaves, plant height, number of tubers, clump wet weight and weight of dried tubers storing age groups 4 days after harvest. From the results of the study there was a single reaction to the number of leaves, plant height, tuber number, clump wet weight, and weight of dry tubers storing 4-day age groups after harvest from white KNO3 fertilizer with 15 t/ ha and 450 kg / ha by obtaining store dried shallots as much as 9.3 gr / plant, equivalent to 9.3 t / ha
