Abstract

Flood is one of the most frequent hydrometeorological disasters which leads in economic losses. The first step in flood disaster mitigation efforts is mapping vulnerable areas. Kencong District frequently affected by the annual flooding event. This study aims to assess flood hazard mapping by integrating the AHP method and Geographic Information System. This study used a descriptive quantitative approach through the correlation matrix of the AHP model for each physical environmental factor. These factors include slope, altitude, distance from the river, soil type, Topographic Wetness Index (TWI), and Curvature. Furthermore, with the Geographic Information System (GIS), the weighted overlay stage was carried out to obtain the results of flood-prone areas. Based on the AHP analysis, the most significant factors in determining flood-prone areas were the distance from rivers, slopes, and TWI. The results of flood-prone areas mapping were divided into five classes: from deficient 0.02%, low 4.26%, medium 37.11%, high 51.89%, and very high 6.72%. Validation of GIS mapping results with data in the field has an AUC value of 84%, which indicates that the prediction of the AHP-GIS model is perfect in flood-prone areas mapping in the Kencong District. The integration of AHP method and Geographic Information System in flood hazard assessment were able to produce a model to evaluate the spatial distribution of flood-prone areas.

Abstract

Geography Learning in XI Social Science Classes still dominated by conventional teaching methods that make students become unmotivated in learning. Therefore, it is necessary to apply a model of learning that can foster activity and student’s level of knowledge. The Group Investigation Learning model (GI) has several advantages. Advantages of Group Investigation Learning model among others: (1) increase the ability to think critically, (2) creating a learning environment that is democratic, (3) enhance the development of soft skills, (4) may improve social solidarity, dan (5) improve student’s level of knowledge to learn. The purpose of this study to analyze the influence of group investigation learning model towards the level of mangrove knowledge of students in senior high school. The type of research is the quasi-experimental study with non equivalent control group posttest only design. The subject of the study consisted of class XI Social Science are selected based on the score of Middle Semester Exam (UTS) 2 on 2014-2015 teachings year that had an average of almost the same (homogeneous).The results of this study are showed significant influence of GI models on Geography level of knowledge to learn of students. It was based on the results of the Independent Sample T-Test analysis showed a p-value of 0.000 level. P-level value is smaller than 0.05 (p <0.05). The average score student’s level of knowledge to learn geography experimental class is higher with a score of 208, while the control class w ith a score of 177. That's because the investigations conducted the mangrove forest, teachers simply deliver early learning problems, frequent interaction between students during learning, and students investigate different sub-themes.

Abstract

Selection of the right learning model will increase the chances of achieving student learning success. The choice of learning model should pay attention to students' ability which is generally not the same among students one to another. The main factors are the various intelligence and student backgrounds. In addition, the absorptive capacity of the subject matter between students with one student is not the same so that affect learning outcomes achieved. Therefore, teachers need alternative learning model to overcome the diversity of student characteristics, one of them is with individual learning. However, the large number of students in the classroom and the various shortcomings in individual learning such as the effectiveness of learning, time, effort, and curriculum demands, as well as other obstacles, then individual learning is very unlikely to be implemented. An alternative that teachers can do is through the use of learning models that lead to programmed individual learning. The model of learning in accordance with the problem is Model Team Assisted Individualization (TAI). The TAI model is designed as a learning model that combines individual learning with cooperative learning. With the TAI model, the weaknesses that exist in individual learning and on cooperative learning can be minimized with the advantages that exist in both. This study aims to determine the effect of the use of TAI Model on the results of IPS geography learning. This research includes quasi experiment type, using Pretest-posttest Control Group Design design. The subjects consisted of one experimental class and one control class, grade VII student SMPN 4 Lumajang. The research instrument is a test consisting of prates and pascates. The data analysis technique uses t-test with SPSS 16.00 for Windows. The result of data analysis shows that the learning result of IPS geography of students using TAI model is better than students who do not use TAI Model. Thus it can be argued that the use of TAI model influences the learning outcomes Geography IPS Geography students proposed for teachers in the field of study Geography is to make the Model TAI as an alternative model of learning to improve student learning outcomes. Suggestions for further research are piloting the TAI Model on different materials and levels of higher classes or schools, as well as combining with more varied learning media so as to show a great influence on student learning outcomes and gain greater benefits from the TAI Model.

Abstract

Jember regency has several areas that are morphology of folding hills and mountain folds. The part of landslide prone zone is closely related to the slope of the slope. Areas with a sloping slope of more than 15º need attention to the possibility of a landslide disaster. Interconnection contacts with weathering of rocks, settlements and land cover also affect the landslide potential. The existence of Ijen Volcano that produces volcanic rock deposits that are generally not yet unified will increase the potential for landslides in Jember Regency. Landslide has occurred one of them on Gunung Gumitir Street which is the main route of Surabaya-Jember-Banyuwangi traffic. In May 2016 this street is hit by landslide, so the flow of traffic through this lane is paralyzed and must be diverted to a further path, which rotates to Situbondo City. The transfer of this pathway resulted in a loss to the local community and who crossed the path.The occurrence of landslide disaster shows that Jember Regency area is vulnerable and potentially return to landslide. Therefore there is a need for a solution to solve this problem. One solution to solve the problem is by utilizing Geographic Information System (GIS) application. The purpose of this research is to analyze zonation prone to landslide in jember district. The design of the research is Geographic Information System overlay analysis. This design combines several parameters in the determination of landslide-prone zones. This design combines several parameters in the determination of landslide-prone zones. The parameter used in this research is (1) land use, (2) topography, and (3) soil.Based on the research results, it can be known zone with highest to lowest vulnerability level. Zone with very high level of vulnerability is located in Panti sub-district, Sumberbaru, Sukorambi, Dyke, Silo and Jelbuk. The zones have similar characteristics that include (1) soil type of andosol, (2) clay texture, (3) uncompacted rock, (4) slope of 30⁰-40⁰ (steep and very steep), and (5) land use for settlements and plantations.
