Descriptive Survey

The potential for land movement in South Tapanuli Regency included in the high hazard potential. South Tapanuli Regency is in an area with a high elevation, and the region is in a large fault zone of Sumatra and high rainfall. The purpose of this study was to determine the spatial distribution of landslide vulnerability in the South Tapanuli Regency. The method used in this study is a qualitative descriptive survey and using the landslide vulnerability method with parameters: natural factors and management. The analysis used in this study is an overlay of predetermined parameters and weighting. The results showed that the area of ​​South Tapanuli Regency divided into 4 (four) landslide hazard classes, which were slightly vulnerable, somewhat vulnerable, vulnerable and very vulnerable with an area of ​​183 km² or 4.20%, 825.66 km² or 18.95 %, 2,092.58 km² or 48.04% and 1,254,253 km² or 28.78%. And the most dominant is the vulnerable class. For the vulnerable class, there are only a few weak areas, namely in the District of Muara Batang Toru, precisely in the villages of Lumut and Janji Maria. For class vulnerability, it is somewhat vulnerable to dominate almost all of Batang Angkola and Muara Batang Toru and South Angkola Districts around Tolang Jae village. For the vulnerable class, Rawan dominates in the Districts of Batang Toru, Sayur Matinggi Sipirok, Aek Bilah, and Saipar Dolok Hole. And for the vulnerable class, it is very vulnerable to dominate in the Districts of Marancar, Sipirok, Ass, and South Angkola.

Peste Des Petits Ruminants

Objective. Estimate the prevalence and spatial modeling of PPR in the small ruminant population of Chaharmahal and Bakhtiari, Iran, during 2009–2014. Materials and methods. Data were collected from veterinary organization and Offices in Chaharmahal and Bakhtiari province and data analysis was carried out using and IBM SPSS version 22 and Office 2010. For spatial modeling geographic information system (QGIS and PCI-Geomatic) was used. Results. This study showed that the overall prevalence of PPR during the years 2009 to 2014 was 1.37%. Koohrang, Ardal, Lordegan, Ben, Borougen, Shahrekord, Farsan and Kiar cities had the highest prevalence of PPR, respectively. The highest PPR infection rate was observed in the March and goat more affected rather than other ruminants. Conclusions. Our findings provide evidence of a rather common prevalence of PPR and its spatial distribution in Chaharmahal and Bakhtiari province. Using statistical tests for data analysis of PPR and its spatial modeling researchers can predict the incidence of disease in the future and could select appropriate measures of disease control.

Van den Bosch fortress is located in Ngawi East Java Indonesia. The fortress’ unique location in the riverbanks of two main rivers of Java island, i.e. Bengawan Solo river and Madiun river, boosts its potentilas as a cultural tourist attraction. The meeting point between these two big rivers has given the fortress opportunities to develop unique tourism package. This study examined the potentials of the fortress, problems for developing the fortress, and the interconnection of spatial distribution of the fortress by employing geographic information system (GIS) to develop spatial-based management of the fortress as an intergrated cultural tourism site. Spatial-based management of the historical resource is aimed at combining and enhancing the urban elements including town square, traditional market, fortress, and rivers as well as some supporting facilities; and it is expected to be able to make Van den Bosch fortress as the center of the attractions. All of the elements of the urban area need to be spatially planned and managed in order to perform a unique tourist attraction in the most enticing historical destination of the region. Keywords: cultural tourism, fortress, historical asset, spatial-based management.

Flood Prone Areas

This research is about flood vulnerability mapping in Jambi City based on Geographic Information System (GIS). This study is aiming to find out the flood vulnerability level, spatial distribution of flood, and flood prone areas in Jambi City. We used five parameters that affect flood vulnerability, including land slope, land level, land use, soil type, and rainfall during 2019. The method used is the scoring and overlay method with the help of ArcGis software. Flood vulnerability level was divided into three categories, namely quite vulnerable, vulnerable, and very vulnerable. The results obtained in this study are that most of Jambi City has a level of flood vulnerability in the vulnerable category, which is an area of 9254.82 ha (58%), while for the area that is dominated quite safe from flooding, Jambi Selatan sub-district, is 2849.14 ha (18%). This shows that more than half of the Jambi city area is a flood-prone area so it is very important to carry out structural and non-structural mitigation actions
