Abstract

Transformation Land change that occurred in Cilegon City is a phenomenon that involves a significant transformation in urban land use over the last few years. Land is a natural resource that has an important function to meet various human needs. This change was caused by several factors, one of which was rapid population growth. This research involves analyzing satellite imagery from several different time periods to track the evolution of land use in Cilegon City. From the results of observations made, it is known that there is a reduction in green land in Cilegon City. Where in each period of the year there are changes in green land which is increasingly decreasing. This reduction was caused by several factors, namely the transfer of land function from greenland to housing and the occurrence of fires on the green land.

Abstract

The balance between the availability of land and the need for control, use and utilization of land based on regional functions is important as a reference for sustainable development directions and maintaining environmental sustainability. Imbalance in land use affects the direction of development and environmental sustainability. For this reason, it is necessary to conduct an analysis to determine the balance between land availability and land needs within a certain period of time through the preparation of a land use balance based on regional function directions. This research aims to analyze the balance between land availability and land use as well as the suitability of land use for the direction of regional functions. The method in this research uses a multi-temporal approach by utilizing remote sensing technology and geographic information systems. The overlay process was carried out to see the land change of Baubau city and see the level of conformity of existing land use with the direction of regional functions. The results show that the 2016 land use balance has the highest assets in forest land use of 21097.66 Ha and the 2020 land use balance has the highest liabilities in forest land use of 20959.56 Ha. The trend of land change in 2016-2020 is the change of forest, open land, mixed gardens, settlements and shrubs/shrubs. The level of conformity of existing land use with the direction of the function of the area is very high with a percentage level of suitability of 90.83% and a level of incompatibility of 9.17%.

Abstract

Logarithm has an important role in learning mathematics since various fields such as science, computer, finance, industry, and others are applied this material as one of the study subjects. In calculus, logarithm has an important role, especially natural logarithm. This study aims to determine pre-service mathematics teachers' difficulties in solving logarithm bases and numerus material. The subjects are students in the first semester in one university at Banda Aceh city who take elementary algebra course. The research was conducted with a descriptive approach to explain the difficulties that students faced, and it applied several steps such as providing logarithm test to students, determining the difficulties, and verifying it by interviewing students who had difficulties based on their answers. This study revealed that there were various difficulties that students faced such as; (1) lack of understanding of bases and numerus definitions of logarithms, (2) not being able to distinguish between expressions and logarithmic equations, (3) remembering too many formulas so that they do not understand the context of the problem, (4) couldn’t determine the position of irrational numbers on the number line.

Abstract

The importance of students' mastery of statistics is supported by the inclusion of this material in the mathematics curriculum since primary and secondary education. The role of statistics itself has penetrated into various professions and fields of science. Regarding statistical mastery students need to have statistical literacy skills in the form of basic skills in reading graphs, graph titles or themes, giving meaning to units of graphs, finding certain values or units, determining maximum and minimum values or the difference between the two. This study aims to describe students' errors in solving statistical literacy test similar to minimum competency assessment or asesmen kompetensi minimum (in Indonesian) based on the Kastolan stages. The type of this study is qualitative research with a case study design. The subjects of this research were 5 students of grade 11, a senior high school in Banjarbaru, South Borneo, selected using purposive sampling technique. Data were collected using tests and interviews. During the study, it was found that errors made by students include conceptual errors, procedural errors, and technical errors. Students' errors in solving statistical literacy test can have an impact on their daily life when they are dealing with data. Moreover, errors made by students when solving problems can be an early sign that there are learning obstacles experienced by students.
