Abstract

Government of Indonesia planned to build 30.000 embung in 2017. Embung or mini reservoir is one of soil and water conservation methods to decrease surface runoff, enhance water surface retention, and increase water entering to the soil by infiltration, that finally influence the values of Discharge Ratio and Runoff Coefficient of a watershed. This research that was done in 2017 is about the effect of embung and it’s combination with other soil and water conservation technics (strip cropping and agroforestry) on Discharge Ratio (DR) and Runoff Coefficient (RC) in Cilemer Watershed by using SWAT method. The result shows that the Scenario 1 (mini reservoir technic alone) decreased DR and RC by 25.45% (from 119.70 to 94.25) and 32% (from 0.25 to 0.17), respectively. The Scenario 2 (combination of embung and strip cropping) decreased DR and Runoff Coefficient by 40.92% (from 119.70 to 78.78) and 32% (from 0.25 to 0.17), respectively. The Scenario 3 (combination of mini reservoir and agroforestry) decreased DR and RC by 41.38% (from 119.70 to 78.31) and 36% (from 0.25 to 0.16), respectively. The application of mini reservoir and its combination with other soil and water conservation (SWC) techniques were able to decrease DR and RC meaningfully.

Abstract

Ponjong and Semanu Districts, Gunungkidul Regency are included in Gunung Sewu Karst mega system which has the variety of morphologies. Karst morphologies were formed as the result of karstification that could have negative impacts, such as doline’s modification impacts land subsidence occurrence. Therefore, the aim of this research is to know the potential of land subsidence by determining characteristics and distribution pattern of doline. Those characteristics of doline are karst terrain, vegetation density, and surface temperature. This research used SRTM data and Landsat 8 to identify those characteristics of doline. Furthermore, using analysis doline’s morphometric and Nearest Neighbour Analysis (NNA) method used to find the distribution pattern of doline. Based on its characteristics, doline is divided into wet and dry. Doline has three different shapes, which are oval, round, and irregular. Those dolines have the group distribution pattern (NNA index 0,843). In Semanu District formed a clustering pattern, indicating further development of karstification of doline when compared with in Ponjong District which still tend to be random. Characteristics of clumped doline are found in lowland terrain forms with medium vegetation densities and high surface temperatures, while random ones have a bumpy terrain field shape with dense vegetation densities and low surface temperatures.

Abstract

Disaster is a common thing experienced by people in Indonesia and become its own problem. People who are accustomed to disaster have local knowledge in disaster mitigation. Local knowledge or local wisdom is the result of the adaptation and experience of events that have occurred in the area. This research takes place in Tieng Village, Dieng, Kejajar District, Wonosobo Regency. Tieng Village is an area prone to landslides and has been hit by flash flood on 18 December 2011. The flood disaster caused loss of life and loss of property that is not small. The research method used is descriptive qualitative with structural approach related to collective awareness of society. The purpose of this study is to analyze the mitigation efforts undertaken by local wisdom-based communities in Tieng Village. The result of this study is that people have a common awareness to perform the mitigation that is demonstrated by the habit of going out and going to safer places by bringing securities when there is heavy rain with high intensity more than two hours, once a month working to clean river and plant trees , often held socialization about floods and landslides especially when the rainy season, and people have an understanding that they must be wise to nature

Abstract

The high intensity rainfall in December 21st 2016 has caused major flooding in Bima City. It caused infrastructure destructs and considerable losses. The condition of the watershed in the upstream experiencing decrease of forest area and the gorwth of the city were suspected as some of the factors causing the big flood. Significant land-use changing brought impact on the changes of watershed response to rainfall. The purpose of this research was to determine the effect of land use changing on the flood occurence based on the hydrological model of rainfall-flow in Rontu watershed in the City of Bima. In this research, the effect of land use changing was analyzed by determining the value of curve number (CN) of the watershed in 1996, 2006 and 2016. CN was calculated with the help of HEC-GeoHMS 10.3 software. Furthermore, CN value was used in effective rainfall calculation as the input of hydrograph flood simulation by using the Nakayasu synthetic unit hydrograph transform model. The result showed that other than extreme rainfall, the flood was also affected by the land use changing. In Rontu watershed, over the past twenty years (1996 to 2016), land use changing composition occured i e. 28,68% forest decrease, 3,10% settlement increase, 26,83% farm field incease, 5,82% shrubs decrease and 3,62% rice field increase. Such changing in wet conditions in Padolo sub-watershed resulted in increasing CN of 4,55%, peak discharge of 10,26% and runoff volume of 9,82% and in Malayu sub-watershed resulted in increasing CN of 6,78%, peak discharge of 17,29% and runoff volume 18,00%.

Abstract

Tourism is one of the priorities of the national development in the fields of economy, tourism development including forms of village tourism. Based on the decision letter of the Regent of Bandung Number 556.42/Headers. 71-Dispopar/2011, Jelekong Village is one that is established as a village, because the votes have characteristic patterns of social life of the community in the form of a unique culture puppetry and painting and puppet craftsman. To develop the area into a tourist village, required an appropriate strategy based on the potential of the resource. The approach that the author use descriptive research, namely through the survey method with variable single research namely development potential of the tourist village, where aspects of the physical aspect i.e. the charge indicators will be, social, spatial, buildings, culture, crafts and ceremonies, as well as supporting other tourism indicators such as accessibility, accommodation, community, tourists and tourism managers. As for the results of the study showed that the potential Wards Jelekong village embodiment based on criteria, classified into class II i.e. enough potential to be developed. Attitude and positive values indicate community participation in supporting its development. Based on the results of the SWOT analysis, the strategies that can be used in Jelekong village development that is developing and organizing potential attractions; preservation of customs; accessibility improvements; develop various infrastructure supporting tourism; partnering with related stakeholders and investors; improving promotion; engaging the public in every stage of the development of village tourism.
