The Difference

The development of student potential is influenced by how the teacher prepares the steps of the learning process. This means that teacher’s preparation and planning for the learning process determines the achievement of learning objectives. There is an indication that students have low mastery in the skills of imagery analysis on the topic of remote sensing. This research aims to find ways to assist students in the learning process of remote sensing and find about the appropriateness of the form of learning process to the learning materials as well as the allocated time and the steps in the learning process. More specifically, it aims to assist students in gaining understanding and ability of image data analysis using Er Mapper software. The population consisted of 195 students, while the sample taught to improve their understanding of the steps taken in imagery analysis only included 90 students. The students were divided into two groups, the control class and the experimental class, with 45 students respectively. In assessing students' understanding, this research was aided by four testers who assessed and determined the time taken for students to complete each stage of imagery analysis, with the criteria of: 1) 0-1 (very fast), 2)> 1-2 (fast), 3)> 2-3 (slow), and 4)> 3-4 (very slow). The scores of the imagery analysis of the control class and experimental class students were 3.30 (very good) and 3.38 (very good), respectively, with a difference of 0.08. The difference in the understanding and ability was more strongly indicated by the speed or time taken to complete the analysis stages for each meeting. The control class’ average speed was 3.51 (very slow), while the experimental class was 1.44 (fast). To accelerate the learning process of image analysis, the lab work should be assisted with guidebooks or modules in each meeting. With the module, students can learn independently.

Klaten Regency is one of the regencies in Central Java Province that has an increasing population every year. This can cause an increase in built-up land for human activities. The built-up land needs to be monitored so that the construction is in accordance with the regional development plan so that it does not cause problems such as the occurrence of critical land. Therefore, it is necessary to monitor land use regularly. One method for monitoring land use is the remote sensing method. The remote sensing method is much more efficient in mapping land use because without having to survey the field. The remote sensing method utilizes satellite imagery data that can be processed for land use classification. This study uses the sentinel 2 satellite image data with the Object-Based Image Analysis (OBIA) algorithm to obtain land use classification. Sentinel 2 satellite imagery is a medium resolution image category with a spatial resolution of 10 meters. The land use classification can be used to see the distribution of built-up land in Klaten Regency without having to conduct a field survey. The results of the study obtained a segmentation scale parameter value of 60 and a merge scale parameter value of 85. The classification results obtained by 5 types of land use with OBIA. Agricultural land use dominates with an area of 50% of the total area.

Remote sensing technology can be used to obtain information bathymetry. Bathymetric information plays an important role for fisheries, hydrographic and navigation safety. Bathymetric information derived from remote sensing data is highly dependent on the quality of satellite data use and processing. One of the processing to be done is the atmospheric correction process. The data used in this study is Landsat 8 image obtained on June 19, 2013. The purpose of this study was to determine the effect of different atmospheric correction on bathymetric information extraction from Landsat satellite image data 8. The atmospheric correction methods applied were the minimum radiant, Dark Pixels and ATCOR. Bathymetry extraction result of Landsat 8 uses a third method of atmospheric correction is difficult to distinguish which one is best. The calculation of the difference extraction results was determined from regression models and correlation coefficient value calculation error is generated.

The Impact

The Covid-19 pandemic has wholly changed all aspects of life, including the learning system in higher education. So that the learning process must be carried out with a total distance education model, in its implementation, it is not accompanied by good planning. The main purpose of this study is to describe and examine the differences in the experiences of lecturers and students in carrying out the learning process with the distance education model as the impact of the Covid-19 Pandemic. This research was conducted using a descriptive quantitative approach and a different test. The research instrument is a questionnaire designed based on distance education theory. The measurement scale uses a Likert scale (1=strongly disagree to 5=strongly agree). Data were collected through surveys to lecturers and students. Due to the Covid-19 pandemic, the questionnaire was designed in a Google Form and distributed through the WhatsApp Group of colleagues at several Islamic Universities in Indonesia. The number of respondents collected was N=527 (n=123 lecturers and n=404 students). Before data analysis, data were edited, and the result was that all data were declared valid. Data analysis used the Categorization Index and a different test with the Independent-Samples Kolmogorov-Smirnov Test approach. The results of the descriptive research show that the learning process using the distance education model, from the experience of the lecturers, is stated to be less effective and even tends to be ineffective. Student experience also shows the same thing, which is less effective, and the small number of many students say it is effective. The difference in experience in the learning process with the distance education model between lecturers and students is different. This difference is caused by the habit between lecturers and students using information technology devices as a medium in distance education that is not the same.

The Individual

This study discusses several aspects of differences in general for each individual which includes, among others, differences in aspects: biological, psychological, intelligence, gender, ethnicity, and so on, as well as their implications in the learning process in the classroom. This research is library research, which aims to collect information related to individual differences and their implications in the learning process in the classroom. Research data collection was carried out using documentation techniques. The data analysis used inductive analysis. Based on the data analysis that has been done, it can be concluded that the individual characteristics of each lie in the biological (physiological) aspect, as well as the psychological aspect. These two aspects form a certain behavior in humans that makes them different from other humans. In addressing these differences, in the learning process in the classroom, teachers should be creative in managing the learning process in the classroom so that learning objectives can be achieved optimally.
