The research design uses a combination of quantitative and qualitative research, with simultaneous models not balanced. The population of the research was Mathematics Department students of FMIPA UNNES in 2017/2018 who had participated in complex analysis studies consisting of two classes with a population size of 68. The samples were randomly selected from two classes with a sample size of 33. The four subjects were selected from two levels. Criticaland normal of each of the two students. Data were analysed quantitatively and qualitatively. The results of the study show that student learning outcomes on achieving critical mathematical thinking ability in complex analysis learning are complete. There are two levels of students’ critical thinking ability, namely critical and normal levels. The results of the analysis of students’ mathematical critical thinking ability, subject to a critical level, there are four indicators of questions that have not been reached. These indicators include aspects of assumptions, deductions, interpretations, and judging arguments. Subjects are of normal level, there are eleven indicators of questions that have not been reached. These indicators include all aspects of mathematical critical thinking ability namely, inferential, assumptions, deductions, interpretations, and judging arguments. The diagnosis of errors found that subjects with normal levels experienced errors of all types, namely errors of understanding, process, conclusion, transformation, and carelessness, as well as lack of material mastery. Subjects with critical levels experience misunderstanding and conclusions.

Published: November 2019

Abstract
This study aims to describe the results of the socialization of natural experience (jelajah alam sekitar, JAS) approaches on the learning held by science teachers’ members of MGMP IPA sub rayon 04 Kota Semarang through study of learning tools and testimony. This study is a case study that is intended to describe the results of the impact analysis of JAS learning approach socialization to the target audience mentioned above. The results of the study indicate that at the beginning of the activity before the socialization, 62.5% of the participants had known JAS and stated positive things about JAS, such as activating teachers and learners, making it easier to understand biology materials, fun and educate critical thinking students. They have also been able to assess the constraints found in learners, especially on time management. With the socialization of the participants can develop lesson plan and other learning tools that are considered relevant to JAS. Nevertheless, in the application of learning it is difficult to achieve the characteristics and nature of JAS on the use of alternative / authentic assessment, exploration of the surrounding environment, and a fun learning / bioedutainment. The results of reflection and evaluation show that many participants have not been able to change the mind set to view the object of biological study in learning from education about to education for. For that, in the future it is necessary activities that lead to best practice of learning management, classroom action research and collaboration.

Abstract
Thinking about the boundary conditions for the formulation of abstract physical principles is needed in solving physical problems. A physics equation cannot simply be applied without regard to the context and requirements that the equation must fulfill. This study has explored the sense of scale in the context of solving physical problems in prospective teacher students, using qualitative descriptive analysis. Respondents consisted of 37 1st semester students, 35 5th semester students and 20 Physics teacher professional education (PPG) students at UNNES. The results of the study showed that sense of scale in solving physical problems in first and fifth semester students was low, while in professional education students were classified as moderate. There was no difference in the understanding of the scale between male and female students. Sense of scale about the measurement limit of a measurement instrument was better. Sense of scale in understanding the boundary conditions for the application of a physical formalism, identifying variables and constants according to context, and predicting a phenomenon based on the finding data was still relatively low.

AbstractIn order to cope with rapid changes in 21stcentury, preparation of pre-service teachers is viewed as crucial to the quality of teacher workforce. This article presents the findings of a study of Indonesian-Thailand pre-service teachers that participated in SEA- Teacher Project. This study used qualitative method to describe pre-service teachers’ perspective on pedagogical challenges as they participated in observations, assist in teaching, teach and reflect. Drawing from participant field notes, surveys and semi-structured interviews, by open-questions this study seeks to investigate the problems. During those phases, this study gathered the pre-service teachers’ field notes that indicates some challenging pedagogical experiences influenced their perspective in teaching mathematics. The findings reveal that language becomes their major challenge in delivering material (80%) that affected their perception in explains a topic, concept or procedure in mathematics. Some of them overcame this problem by developing learning media. Pre-service teachers are given the opportunity to do practice teaching, but some of them (30%) are given only 2-3 meetings, that causes pre-service teachers couldn’t develop variation of teaching strategies. Pre-service teachers did not have enough time to learn school’s curriculum and resulted in students having difficulties in developing lessons plan.They then try to keep the curriculum in their home country (40%) or used the lesson plan as an example in school (60%). Some obstacles experienced by pre-service teacher (20%) as they have to taught large classes (up to 50 students).They had to work hard in order deal with different characters of students so the class remain conductive. In deal with misconception when students make mistakes in working on a problem 90% of them only give the right answer, without exploring the possibility of a misconceptions. In practice only 30% of them identify the cognitive demands of students who are taught during the observation activity and assist of teaching. Limitations on school infrastructure such as LCD, computers, and internet inhibit the pre-service teacher to develop ICT based learning (50%) but they overcome the limitation by developing students’ worksheet and contextual mathematics model.

Published: November 2019

Abstract
The question raised in the article concerns scenario planning and its role in improving the efficiency of the economic entities of the poultry industry. The relevance of scenario planning, which is considered as a mechanism for responding to changes in the environment, is substantiated. The analysis of the main volume indicators of poultry production for 2018 both in the whole industry and in the context of regions is given and the presence of the Delta in these quantities is justified. One of the reasons for the difference in the existing indicators is the lack of scenario planning in individual economic entities. In this regard, a specific example shows the scenarios of planning the technology of meat production of broiler chickens when using the rearing of roosters up to 8 weeks of age and justified their economic feasibility.

Published: November 2019

Abstract
The research is conducted in order to improve territorial organization of agriculture in context of the implementation of use strategy of adaptive-landscape land basing on the assessment and analysis of spatiotemporal structure of natural agro-potential of the territory. The results of dynamic statistical modeling of the standard crops yield in administrative regions of the Samara region are used. A mesoscale comprehensive assessment zoning of the territory is made: seven mesozones are allocated according to compliance of standard yields with crop productivity factors (correlation coefficients with many indicators 0.7-0.9), and assessed districts in them with the most uniform conditions (coefficient of variation within 10%). Assessed zoning is made in administrative contours of Samara region, and it forms geographic basis for solving agro-production issues of organizing adaptive-landscape land use system and crop rotations design. The basis of field crop rotations in innovative technologies in central and southern districts of Samara region are grain-fallow and grain-fallow-cultivated field crop rotations with the optimum specific weight of "black" fallow and winter crops in them. In forest-steppe area grain-fallow-grass-cultivated and grain-cultivated rotations with full and green-manured fallows, perennial grasses and leguminous crops are promising. For their implementation, an analysis of agricultural crops appropriate placement in assessed mesozones is carried out. Crops location according to soil and climate territory specification makes it possible to solve problems of preventing soil and agro-landscapes degradation most effectively, taking into account environmental effect of crops and agro-technologies.
