Landslide is a frequent disaster in Indonesia that is affected by several factors. Cisolok, Cikakak, Pelabuhanratu, and Simpenan are Sub-district that has physical characteristics which can increase the potential of landslides in the area. Therefore, mitigation efforts by potential landslide mapping are needed in the research area. In this research landslide potential map was made by using 3 methods: SMORPH (slope morphology), Index Storie, and SINMAP (stability index mapping). This study is aim to knew the differentiation of spatial pattern of the landslide potential areas by SMOPRH, SINMAP, and Index Storie methods. Spatial analysis was implemented by overlay technique between landslide potential area with landslide location. The result reveal that the research area was dominated by high potential based on the SMORPH method, low by SINMAP, and moderate by Index Storie. The result also reveal that 33% of the total research area has different potential and 7% has the same potential in the results of all three methods. Where areas with high potential in all three methods was distributed in the northern of the study area. The SMORPH method has 19,951 Ha of high potential area and there are 34 landslides in it, SINMAP 2,568 Ha with 32 landlsides, and Index Storie has 4,684 Ha with 21 landslide. The result also explain that in addition to thbeside of slope gradient factor, landuse change factor has a very big affecting for the occurrence of landslide in the research area. Mapping of landslide potential areas in this research is may practically be applied for the regional planning and development of infrastructures in the area.
This research is motivated by the reality of media coverage in constructing political figures for mayoral candidates who campaign through these media. Through the media agenda setting theory, the author examines the SeruJambi.com media in reporting Syarif Fasha as one of the candidates for the Jambi Mayor's candidate in 2018. The analysis goes through three things, namely: message framing, use of words and objectivity. The research method used is interpretive qualitative by emphasizing written sources in the form of documenting the contents of Syarif Fasha's news on the online media SeruJambi.com. The results of the study found that there was an imbalance in Seru Jambi.com in constructing the news of Syarif Fasha as one of the candidates for the Mayor of Jambi 2018. There is a message framing strategy in reporting the daily life of the candidate. The use of words with a simplification strategy from scientific language into everyday language, repetition of words as a pointer to the core idea of the news, synonyms (similar words) by writing different words to prevent boredom. Similarity of topics to clarify a previous sentence, as a framing strategy to highlight the main idea of the news
Abstract. This paper discusses spatial pattern of Hydrologic Response Unit (HRU), which is a unit formed of hydrological analysis, including geology and soil type, elevation and slope, and also land cover in 2009. This paper also discusses the impact of HRU on streamflow of Ci Rasea watershed, West Java. Ci Rasea watershed is located at the upstream part of Ci Tarum watersheds in West Java Province, Indonesia. This research used SWAT (Soil and Water Assessment Tool) model to obtain spatial HRU and river flow. The method used Landsat TM data for land cover and daily rainfall for river flow modeling. The results have shown spatial pattern of HRU which was affected by land cover, soil type and slope. In 2009, accumulated surface runoff and streamflow changes were spatially affected by HRU changes. The large amount accumulation of river flow discharge happened in HRU with landcover paddy field, silty clay soil, and flat slope. While the low discharge of river flow happened in HRU with plantation, clay soil, and slightly steep slopes as HRU dominant. It was found that accumulation of surface runoff in Ci Rasea watershed can be reduced by changing the land cover type in some areas with clay and slightly steep slope to become plantation area and the areas with sandy loam soil and flat slope can be used for paddy fields. Beside affected by HRU, the river flow discharge was also affected by the distance of sub watershed to the outlet. By using NS model and statistical t-student for calibration and validation, it was obtained that the accuracy of river flow models with HRU was 70%. It meant that the model could better simulate water flows of the Ci Rasea watershed. Keywords: SWAT, HRU, landcover, watershed, Landsat, Ci Rasea INTRODUCTIONLand cover changes can increase flood risk (Chubey and Harhout, 2004). The risk is caused by decreasing both ability of land to absorb water and ability of the river to accommodate water flow. Decreasing river water flow could be caused by silting, land conversion in the catchment and excessive groundwater use. Land cover change in the upstream region such as forest change to settlements or open land, also can affect flooding. It will cause increasing runoff due to reducing area of water catchment. The increasing runoff is caused by reducing ability of catchment in holding or permeating the water. The infiltration, surface runoff and évapotranspiration are controlled by the distribution of precipitation, topography, soils, geology and land use within the watershed (Anderson and Burt, 1978;Beven and Kirkby, 1979;Devito et al., 2005).Issey (2011) stated that flood always happens in South Bandung, Indonesia around Ci Tarum watershed area. Ci Rasea watershed is the branch of Ci Tarum watersheds. According to Yusuf (2010), land cover at Ci Rasea watershed from 1997 to 2007 had changed. According to Balitklimat (2007) and Pawitan (2002;2006), land cover changes in the watershed could cause hydrology characteristics of watershed changed.
