This study aims to find out (1) the effect of problem-based learning model on critical thinking skill, and (2) the effect of problem-based learning model on environmental attitude. This study employs a quasi experiment model using pretest-postest for control group design. The subject of the study is Social Science Education Department students of Maulana Malik Ibrahim State Islamic University of Malang, Indoensia who were studying in the odd semester of Academic Year of 2018/2019. The numbers of students in experimental and control class are 25 people. The assessment instrument used for environmental attitude is Likert scale, and essay test is used for assessing the critical thinking skill. The data analysis in this study used normality test, homogeneity test, and independent sample t-test. The results of the study indicate that (1) learning activity using PBL model affects the students’ critical thinking, because through PBL learning, students are trained to think critically to solve real problems in groups. 2) The learning activity using PBL model affects the students’ environmental attitude, because the problem solving process in PBL learning encourages students to care about their environment.

In this research, we analyzed COVID-19 distribution patterns based on hotspots and space–time cubes (STC) in East Java, Indonesia. The data were collected based on the East Java COVID-19 Radar report results from a four-month period, namely March, April, May, and June 2020. Hour, day, and date information were used as the basis of the analysis. We used two spatial analysis models: the emerging hotspot analysis and STC. Both techniques allow us to identify the hotspot cluster temporally. Three-dimensional visualizations can be used to determine the direction of spread of COVID-19 hotspots. The results showed that the spread of COVID-19 throughout East Java was centered in Surabaya, then mostly spread towards suburban areas and other cities. An emerging hotspot analysis was carried out to identify the patterns of COVID-19 hotspots in each bin. Both cities featured oscillating patterns and sporadic hotspots that accumulated over four months. This pattern indicates that newly infected patients always follow the recovery of previous COVID-19 patients and that the increase in the number of positive patients is higher when compared to patients who recover. The monthly hotspot analysis results yielded detailed COVID-19 spatiotemporal information and facilitated more in-depth analysis of events and policies in each location/time bin. The COVID-19 hotspot pattern in East Java, visually speaking, has an amoeba-like pattern. Many positive cases tend to be close to the city, in places with high road density, near trade and business facilities, financial storage, transportation, entertainment, and food venues. Determining the spatial and temporal resolution for the STC model is crucial because it affects the level of detail for the information of endemic disease distribution and is important for the emerging hotspot analysis results. We believe that similar research is still rare in Indonesia, although it has been done elsewhere, in different contexts and focuses.

Environmental care attitude is an important factor in protecting the environment. The Adiwiyata Award is presented as the highest recognition for implementing an environmental care attitude. The aims of this study are to (1) evaluate the execution of the environmental curriculum in Adiwiyata schools; (2) to analyze the students’ environmental care attitudes in Adiwiyata schools in the Pati Regency using the new ecological paradigm (NEP) scale; and (3) to examine the students’ environmental care attitudes in Adiwiyata schools in the Pati Regency related to gender differences. Based on the criteria of Adiwiyata schools, they were used as research subjects. The research subjects were chosen using a purposive sampling technique. A questionnaire was utilized as a data collection instrument. The new ecological paradigm (NEP) scale was used to assess environmental care attitudes. This study used a Likert scale to assess environmental care attitudes. The Mann-Whitney test was used to identify gender differences in environmental care attitudes. The results found that (1) Adiwiyata schools in the Pati Regency supported the implementation of environmental education in the curriculum, as well as participation in environmental activity programs and the use of greenhouses; (2) the environmental care attitudes of students from the SMA Negeri Pati Regency were in the moderate category; and (3) there was a gender difference based on environmental care attitudes, which found that female students have a higher environmental care attitude than the male students. Environmental education plays an important role in gender differences because the Adiwiyata school has integrated learning activities with the environmental education curriculum, and participatory-based environmental activities can improve students’ environmental care attitudes. The potential implication for policy and practice in the field is that humans will consciously prevent environmental problems from occurring.

There has been an increasing trend of land area being brought under human’s use over time. This situation has led the community to carry out land-use development activities in landslide hazard-prone areas. The use of land can have a positive impact by increasing economic conditions, but it can have negative impacts on the environment. Therefore, this study aimed to identify the landslide hazard, focusing on the development of a landform map to reduce the risk of landslide disaster in JLS, Malang Regency. The integration of remote sensing and geographic information systems, as well as field observation, were used to create a landform map and a landslide susceptibility map. Using the geomorphological approach as a basic concept in landform mapping, the morphology, morphogenesis, and morphoarrangement conditions were obtained from the remote sensing data, GIS, and field observation, while morphochronological information was obtained from a geological map. The landslide susceptibility map was prepared using 11 landslide conditioning factors by employing the index of entropy method. Thirty-nine landform units were successfully mapped into four landslide susceptibility classes. The results showed that the study area is dominated by a high level of landslide susceptibility with a majority of moderate to strongly eroded hill morphology. It also reaffirms that landform mapping is a reliable method by which to investigate landslide susceptibility in JLS, Malang Regency.

PBHL is a learning model that combines PBL with hybrid learning. This study aims to 1) determine the effect of the PBHL model on spatial thinking ability and 2) determine the effect of the PBHL model on geography learning outcomes. This study uses a quasi-experimental design of the pretest-posttest control group. The research subjects were students of the Social Sciences Education Program, Uni-versitas Islam Negeri Maulana Malik Ibrahim Malang, Indonesia. The selection of research subjects uses purposive sampling and obtained the experimental class (32 students) and the control class (28 students). This study uses the instrument of spatial thinking ability adopted from Huynh and Sharpe in the form of multiple choice tests and the instrument of learning outcomes assessment in the form of essay tests. Data were analyzed with an independent sample t-test which was previously tested for normality and homogeneity prerequisites. The results of the study concluded that 1) the PBHL model had a significant effect on spatial think-ing ability and 2) the PBHL model had a significant effect on geography learning outcomes. The average gain score of spatial thinking ability and geography learn-ing outcomes in the experimental class is higher than the control class. Sugges-tions for further research with different subjects and variables, integrated e-learning application should be used to make the planning and implementation of PBHL learning easier and more successful.
