From 2014 to 2016, the number of prevalence of Dengue Hemorrhagic Fever (DHF) and deaths associated with DHF in Indonesia increased. DHF fatal cases were also reported from three administrative units in the Special Region of Yogyakarta, namely Bantul Regency, Gunungkidul Regency, and Yogyakarta City. Two related deaths in Purwosari, a district in Gunungkidul, raised the status of DHF to an outbreak. This study was designed to characterize the spread pattern of DHF in its endemic areas in Purwosari District using the retrospective method, anamnesis, in-depth interviews, Geographic Information System (GIS), and environmental analysis. The kernel density estimation revealed that in 2011-2017, DHF was concentrated in four villages, namely Giriasih, Giricahyo, Giritirto, and Giripurwo. There was a correlation between DHF incidents and physical geographical features of these villages, including proximity to water sources, high vegetation density, elevation, humidity, and rainfall, which created habitats for mosquito growth. A high incidence of DHF has been observed in children (50.8%) and students (57.4%), with most cases (78.7%) showing typical symptoms of the disease. A few of the 61 cases in the district developed into dengue shock syndrome (DSS) and led to death (4.9%), mainly because the public was unable to recognize the warning signs of DHF early and had limited knowledge of required management therapy. Moreover, the preventive or precautionary measures known as the 3M-Plus were not fully implemented yet.

The qualitative parameters of development of a quantitatively increasing population for a resource stressed country like India, is dependent on the sustainability of food availability. Agriculture remains to be a backbone of the economy and food supply. Agriculture, however, in many parts of India, even today, remains to be rain-fed. Recent efforts at the government level, Centre and State, have helped to bring a significant amount of land, initially under rain-fed agriculture, to under irrigation of various types. These varied types of irrigation change regionally; on various agro-factors. Source of water resources to be used for irrigation in the respective climatic sub-regions and the subsequent crop cultivated in the respective region are just a few primary factors controlling the effectivity of the type of irrigation method used. Irrigation requires technological inputs, which, in turn, requires financial expenses that need to be under the significant agro-factors mentioned above. Governments at the Centre and State levels; have been continuously making efforts to support irrigation practices through direct and indirect supportive schemes. These schemes have their positive, and at times, negative impact on the local agriculture at a micro-level. Agriculture is a state subject in India. The Centre does provide finance for various agricultural projects as well. Micro-irrigation has been and will play an essential role in the future in India. Ever since 1992, the government has been taking initiatives in micro-irrigation. These have eventually transpired into schemes, i.e., Centrally Sponsored Scheme (CSS) in 2006, later upgraded to the National Mission on Micro Irrigation (NMMI) implemented since 2013-14 and subsequently National Mission for Sustainable Agriculture. The present study is an attempt to evaluate such 'State' (Central and State Governments)sponsored irrigation programs on agricultural practices at a micro level, over a decade (2005-2016). The study area identified for the same is a tahsil in the Ahmednagar district of Western Maharashtra. What is significant is that, the said tahsil Shrigonda; lies in the drought-prone region and that there have been cyclic variations in the rainfall, and the various agriculture crops cultivated through the last decade. State Government-sponsored schemes are seen to have been blended with Central Government schemes by the local farmers to achieve sustainability of crops. The effects of the same, on the cycle of products, is worth an observation.Human factors also play an equally important role while using the developing Technology of micro-irrigation. Farmers try-and-test various crops with the respective Micro-irrigation technique, in the respective agro-climatic regions, particularly when the source of water is not assured in the drought-prone area. Subsequent allied government schemes (farm ponds), the market value of the product, and perishability or shelf-life of the products also play a significant role in the choice of crop. The success of the micro-irrigation schemes will, however, be dependent on the effective delivery mechanism through close coordination among all the tiers of government and capacity building of beneficiaries.

The presence of spacecraft in ionospheric plasma can change plasma properties, vice versa plasma can lead to charge buildup on spacecraft. The level of charging, through electric potential of spacecraft, initially depends on plasma density. However, simulations done on four LEO satellites, i.e. ERS 1, MIDORI, ASCA and FUSE 1, showed that charging level depends on plasma electron temperature rather than plasma density which satisfied the Boltzmann’s relation in the absence of high-energy electrons from aurora. The higher the plasma electron temperature the more spacecraft exposed to negative charging. It is assumed that plasma ions and electrons are collisionless or in Maxwellian distribution. It is found that there is no strong relation between density and charging level. Furthermore, there exists insignificant different of charging between polar and equatorial satellites. It means that the placement of satellite in polar or equatorial region, as long as the presence of auroral electrons is excluded, will suffer similar level of charging which is less than 5V (negative). Since spacecraft are exposed to negative charge, electric field generated by spacecraft potential, together with mesothermal motion effects, deflects ion trajectory into donwstream region leading to ion void region. The ion density is reduced compared to electron density, but there is no significant different of ion void feature between polar and equatorial satellites.and capacity building of beneficiaries.

The Western Waters of Indonesian (WWI) present a diverse interaction of ocean-atmosphere dynamics. One of them represents the event of Indian Ocean Dipole (IOD), El Niño–Southern Oscillation (ENSO), and upwelling. The objective of this study is to determine the dynamics of chlorophyll-a concentration (Chl–a), especially during IOD and ENSO. Also, this study is aimed to examine the temporal and spatial distribution of the upwelling area from 2000 to 2017. The data utilized consisted of Chl–a, wind stress, Sea Level Anomaly (SLA), and Sea Surface Temperature (SST). The technique used to determine the upwelling area was by examining the maximum conditions of Chl–a, the low temperature of SST, and SLA. The results showed the sea surface temperature had a relationship with the concentration of Chl–a. It was obtained if the Directional Movement Index (DMI) and N3.4 (Niño 3.4 Index) moved stably (not too fluctuation) resulting in high concentrations of Chl–a. High standard deviations of SST are recognized around the Sunda Strait (June – October). When the standard deviation of SST is high, there is also a tendency for high Chl–a concentrations, while the results of empirical calculations show that large areas of upwelling occurred in January and September respectively at 12,447.72 km2 and 8,146.20 km2. Based on the results of the analysis, it can be concluded that the upwelling does not only occur at the coastal area of Western Sumatra (coastal upwelling), but it also occurs in the eastern territorial waters of the Indian Ocean. In addition, the upwelling area has the same pattern as the Chl–a concentration in January - October.

Publisher : Faculty of Geography, Universitas Gadjah Mada

Indonesian region frequently experiences a prolonged drought and/or flood hazard One of the key factors that often triggers these Awards is the occurrence of seasonal rainfall anomaly. To minimize the possible impact of such extreme event, it is necessary to develop a model that can be applied to predict the wet season onset and wet season rainfall. This paper is a preliminary effort on this mailer. As a pilot study, Yogyakarta Special Province (DIY) has been selected for this purpose. In particular; the analysis is emphasized on the Adisucipto airport station, Yogyakarta, as it is one of the first-class climatological station in DIY which has a very good and long data required for such intention. Detail objectives of this study are to address the following three questions: (1) is it possible to predict wet season onset in Adisucipto airport station using local and regional atmospheric indicators? (2) if it is possible and the model(s) have been developed, can the model(s) be applied for predicting the onset of wet season in other parts of DIY and its surround? (3) does an early or late onset of wet season provide any indication to subsequent rainfall during the wet season? To achieve these objectives, the study requires several types of data including daily rainfall data, monthly air pressure data, Southern Oscillation Index (SO!) and Sea Surface Temperature data. Most of the data cover the period of 1976 to 2001. Methods that have been applied to meet the goals are statistical descriptive and simple liner regression analysis. The results suggest that: (I) wet season onset time in Yogyakarta can be predicted using both local and regional atmospheric factors. namely August and September SOI, and air pressure index at Adisucipto airport station in June. July and August; (2) models that have been developed for Adisucipto airport station are modest enough to be applied for predicting the onset of wet season at other location; (3) the onset of wet season cannot be used as an indicator to estimate rainfall in wet season itself.

Multisource classification for land-use mapping based on spectral, textural, and terrain information using landsat thematic mapper imagery: A Case Study of Semarang-Ungaran Area, Central Java Projo Danoedoro

Automatic classification of remotely sensed digital data is recognised as a robust and efficient method for mapping various land-cover types over a large area. However when more abstract concept such as land-use is required the automatic classification methods cannot be fully useful. This is due to the fact that land-use is related to various landscape factors, and cannot be mapped merely based on its spectral reflectance. This study tried to develop a knowledge-based technique that incorporates textural and terrain information of the image scene into a spectral-based decision making process for land-use labelling. To do so. six reflective hands of Landsat Thematic Mapper (TM) covering Semarang-Ungaran area. Central Java, were used. In addition, all bands were then be filtered using the so-called textural filter, which can accentuate several statistical parameters within a given window. .1 variance parameter was chosen in order to extract heterogeneity within every 7x7 pixels. and the l'ariance values of the whole image dalaset were then stored as a set of texture-filtered bands. Three bands with the lowest 'between-band correlations' were chosen and added to the reflective bands. Based on the nine-layer image dataset, a standard multispectral classification using maximum likelihood algorithm was run. Parallel to this process, a visual interpretation using heads-up digitisation was carried out in order to generate a terrain unit map containing land characteristics relevant to spatial distribution of the land-use in the study area. Finally. the terrain unit map was superimposed with the tentative land-corer map derived from the multispectral classification process. A final land-use map was generated from the nnthisource data integration, controlled by a formalised knowledge about ecological relationship between land-cover. land-use, and land characteristics exist in the field. It was found that the overall accuracy level of the final land-use map is higher as compared to the result generated from six-band classification. However, the use of textural filter also created an 'edge-effect', which shows misclassified pixels alongside the borders of particular land-use categories. The edge-effect also leads to lower accuracy levels for the corresponding land-use categories. In addition, based on the research findings, further research agenda was also set up.

In the last 10 years, tourism has been rapidly growing in Yogyakarta. Studies show that tourism development in Yogyakarta has led to irritated feelings among local residents. This study aims to measure residents' attitudes toward tourism development in Yogyakarta by using validated measurement properties with a scale that measures residents' attitudes toward sustainable tourism development (SUS-TAS). The instrument was distributed to 1,687 local residents living in three main tourist destinations in Yogyakarta. Confirmatory factor analysis was conducted to measure the validity and internal reliability of each variable. Descriptive quantitative analysis was also conducted to investigate the level of agreement among residents to each variable. Findings support the seven dimensions in the SUS-TAS scale. Perceived social cost and community participation are the variables with the lowest level of agreement among the variables. Results also confirm underlying tourism development problems in Yogyakarta.
