Abstract

One of the natural characteristics of a watershed that ensures the sustainability of ecosystem services is soil. The sustainability of ecosystem services in the Kempo sub-watershed related to soil conditions tends to be in a worrying condition because the sub-watershed is classified as critical. This study aims to describe the relationship between soil characteristics and the sustainability of ecosystem services in the Kempo sub-watershed. Data were obtained from surveys, literature studies, and on-screen digitization of Google Earth images in 2010 and 2019. Modeling of causal loop diagrams using Vensim software. The results show a tendency for ecosystem disservices to occur due to deforestation, which is characterized by the dominance of the negative/balancing behavior type, compared to the positive/reinforcing type. Soil conditions tend to be less supportive of the sustainability of ecosystem services due to high deforestation and intensive monoculture land cultivation. Important changes in the system can be made by addressing deforestation as a significant influence on negative feedback on soil conditions. The CLD model can be used in the development of a framework for assessing ecosystem services and disservices both qualitatively and quantitatively, so further research needs to build dynamic system modeling using Stock Flow Diagrams (SFD).

Abstract

Memahami informasi geomorfologi fluvial penting dilakukan untuk memahami unsur morfogenetiknya. Penelitian ini mempunyai tujuan untuk identifikasi geomorfologi dengan melakukan inventaris data dan informasi menjadi sebuah peta. Metode yang digunakan yaitu survey lapangan dengan pendekatan spasial menggunakan foto udara yang dipotret melalui drone dengan ketinggian 100 m dan RTK (Real Time Kinematik) interpretasi foto udara bukan menjadi pendekatan utama dalam memetakan melainkan survey lapangan yang memiliki peran untuk validasi dan pendetailan pengamatan yang telah diinterpretasi melalui foto udara. Informasi yang diidentifikasi melalui interpretasi dan survei lapangan secara umum antaralain: sistem aliran sungai, sistem lereng, Sistem dataran banjir dan fitur spasial bersifat antopogenik berupa objek buatan manusia. Selanjutnya dilakukan simbolisasi berdasarkan karakteristik morfologinya dan dituangkan dalam peta morfologi sungai. Hasil penelitian berupa peta yang menunjukkan karakteristik morfologi fluvial pada skala detail.

Abstract

Landslide susceptibility map is crucial in disaster risk management and it can be used for regional development plans. Landslide susceptibility map can be made by analyzing parameters that are assumed to affect landslides such as gradient slopes, geology, soil, and climate. Selection of landslide controlling parameters influences the accuracy of landslide susceptibility map. This study evaluates the effect of parameter that’s rarely used which is groundwater. The study area of this research was Kalibawang and Samigaluh Subdistricts, Kulonprogo, Special Region of Yogyakarta, Indonesia. Frequency ratio was used for the method along other parameters which is slope gradient, lithology, lineament density, land use, soil thickness. The result shows that groundwater parameter increase the accuracy by 22,29%. This study suggest that groundwater should be highly considered in landslide susceptibility mapping. In the other hand, groundwater depth mapping remains a challenge because most remote sensing method only detect shallow groundwater. Further research is necessary to develop better method for groundwater mapping using remote sensing or other indirect method.
