Abstract

At this time, education in Indonesia has entered the 21st century, which requires students to have 21st century skills, one of which is problem-solving skills (PSS). PSS is needed in life so that students can solve their problems appropriately, effectively, and efficiently. One way to increase students' PSS is to use varied and innovative learning models, such as problem-based learning (PBL). This research is an SLR study that aims to find out whether PBL can affect the increase in student PSS. The methodology in this study included identifying objectives by creating research questions, drafting implementation for the writing team, screening inclusion, searching for literature/ references, taking the essence of selected articles, screening exclusions, conducting synthesis, and writing studies. This study used one database, namely SCOPUS, with a total of 167 articles in the time period from 2013 – 2022. Then, these 167 articles were filtered by inclusion and exclusion so that 69 articles were obtained that were worthy of review. The results of the review of 69 articles can be presented as follows: (1) Indonesia is the country that has conducted the most research on the effect of PBL on PSS; (2) The fields of study involved in this research are very varied, but mathematics and health dominate the most; (3) The research objects involved also vary with the level of student education that dominates; (4) The general result of this study is that PBL can increase students' PSS, although there are several studies that contradict these results; (5) The learning model used is PBL, which has been combined with other learning models that are more innovative and creative. The conclusion of this study is that PBL can increase students' PSS.

Abstract

Volcanic eruption is one of the phenomena that can change the volcanic landscape drastically. Monitoring of volcanic edifices after eruptions should be considered to further understand the potential hazards in the future. Satellite monitoring is a reliable technique for assessing deformation in a volcano. InSAR was applied to detect material build-up after the eruption phase of Semeru Volcano in December 2022. As a consequence of the opening crater along with the InSAR result, a lahar product after the eruption was deposited in the southwest direction. Significant deformations were indicated by PS-InSAR near the crater, which was characterized by a LOS displacement of -10 to -40 mm/year, indicating scouring of the pyroclastic material moving down the slope. The accumulation of pyroclastic flows from the abrading process below was detected in the proximal zone of Semeru, as shown by the positive LOS displacement ranging from 10 to 40 mm/year. The field survey conforms to the PS InSAR results, where unconsolidated material, ranging in size from gravel to boulders, piles up approximately 4-5 m in Curah Kobokan. Highly unconsolidated material tends to move easily by water and threaten the surrounding settlements. Overlying PS InSAR and drainage pattern in the flank of Semeru, concluding several locations that have a high-risk potential of being affected by lahar flows are Curah Kobokan, Supiturang Village, Pronojiwo District, then Tulungrejo, Pasropan Village, Pasrujambe District, Lumajang Regency.
