Abstract

The purposes of the study are (1) studying the characteristics of the landslide hazard level, vulnerability, and capacity dealing with the seasonal plant farmland, and (2) developing the conceptual model disaster risk of landslide for the seasonal plant farmland at the stato volcano area. Sampling of the land factor was carried out in a purposive way and the sampling of the people was carried out accidentally. The analysis was conducted descriptively, parametric and non-parametric statistics, and spatial analysis of ecological map, land shape, slope, soil and land use. The findings showed that the extremely high landslide risk occurred at the cone shape of the incised volcano and the slope of the incised volcano. The economic vulnerability of one-seasonal crop farmland was about Rp. 8,879,310 ha/year-Rp. 44,036,061 ha/year. While, the socio-economic factor of the farmers was generally characterized by a transition into a periurban area. The conceptual model tated that the resources of seasonal plant farmland with the high risk of landslide can be cultivated with the acceptable risk if the vulnerability of agricultural commodity is low in economic value and the capacity of farmers cultivating it is high.

Abstract

This study aims to determine the effect of problem-based learning models on student learning outcomes. This study is Nonequivalent control group design. The sample in this study was class VII which was determined randomly. The material used is the potential and utilization of natural resources. The data obtained are then tested differently using the independent sample t-test. The results showed that the two research classes experienced positive changes regarding student learning outcomes. In the experimental class the problem-based learning model shows learning outcomes that are better than class controls. Calculation of the independent sample t-test posttest shows that students with Sig. (2-tailed) 0.019, where 0.019 <0.05 means that there is a significant difference. The existence of significant differences indicates that there is an influence of problem-based learning models on student learning outcomes.

Abstract

Land use is an important variable in determining the incidence of landslide. Whereas the use of agricultural land crops are vital assets socio-economic life of small farmers in the rural areas on land in the area of complex quarter Arjuno volcano in East Java. This makes the direction of conservation of farmland crops indispensable as an effort to suppress landslide disaster risk. This study aims to determine the direction of agricultural land use crops to reduce disaster risk landslide. Survey method based Disaster Risk Level Map Landslide the basis for this study. Referrals are based on landform conservation, land use, and spatial variation landslide disaster risk with regard to geographical location. Analysis is conducted visually descriptive and to the table. The results show that the direction of agricultural land use crops against landslide disaster risk level should pay attention landform, slope, and rainfall. Urbnisasi region rural farming communities change of socio-economic and cultural aspects due to the ease of access to the interaction with urban areas. This has an impact on the orientation of their lives are no longer entirely dependent on land resources so often ignored aspects of land conservation.

Abstract

This study aimed to examine the spectral imagery of Landsat 8 OLI  that can determine the level of tropical karst desertification Maros Pangkep South Sulawesi. The study method is based on the characteristics of spectral imagery of Landsat 8 OLI. Spectral characteristic analysis was conducted based on derivative index values of Landsat 8 OLI of single-channel spectral values, index spectral values, maximum values, mean, minimal index, and spatial analysis. The results showed that spectral imagery of Landsat 8 OLI can be used as the identifier of the desertification process, that is in band 5 whose maximum value is indicated by the spectral value of vegetation. The karst desertification level in the study area showed that 0.3% of the regions were strongly desertified or 0,97 km2 , 4.1% of medium desertified or 12,03  km2, 16.7% were mildly desertified or 49,17 km2, and 78.9% were not desertified or 232,57 km2. Observation results for image accuracy shows that strongly desertified areas of land use are mining and cement industries, the medium desertified areas are utilized for marble mining, the mildly desertified areas are utilized for agricultural land, and not desertified areas land are being utilized for tropical rain forest is still dense.

Abstract

Filtration is a very important process because naturally karst landscapes do not provide good protection against groundwater. This study aims to determine the effect of filtration with sand, biocarbon, and zeolite materials on the pH, EC and TDS values. The research was conducted using an experimental method using three filtration tubes filled with these three materials. Samples were taken from ten different water sources. The results of the analysis show that the filtration process of a combination of sand, biocarbon, and zeolite materials has the effect of increasing the pH value, and decreasing the EC and TDS values. The filtration process through a combination of volcanic sand, biocarbon and zeolith materials simultaneously gives a more significant change in pH, EC, and TDS values compared to filtration with these materials separately.
