A groundwater study has been conducted in the Semarang City in August 2014, aiming to determine the source of shallow groundwater salinization using stable isotopes (18 O, 2 H) and water chemistry approach, and supported by local hydrogeological data. A number of shallow groundwater samples were taken at several locations with a depth of 0-35 m. Based on geological data, shallow groundwater of Semarang alluvium is dominated by insertion of sand-gravel and sandy-clay with average porosity of around 56.0 %. This layer is thinning towards the south and then increasingly thickening to the north and northeast of the studied area. The results of the analyses show that the characteristics of shallow groundwater, i.e. approximately 51% of groundwater, still have the original composition as meteoric water and the remaining approximately 49% obtained a shift in the isotopic composition as caused by interaction with seawater and the little influence of evaporation. The results of chemical analysis of water indicates that in dry seasons, shallow groundwater aquifers in the Semarang City is dominated by chloride (Cl-) with NaCl of water type. While the parameters of bicarbonate, chloride, and Na/Cl ratio, shallow groundwater can be classified into two groups, namely unintruded groundwater around 51% spread from the foot hills to the south towards the hills with elevations of 9-142 m above sea level and intruded groundwater around 49% spread from the coastline to the urban direction.
Geopark in Indonesia has SMEs which are engaged in geoproduct development. Geoproduct are products and services created by the community living in the surrounding geopark areas. Geopark has become a targeted destination for geotourism in Belitong, Indonesia. These geopark have unique geoproduct development. The objectives of this research is to map geoproducts in the geopark and the role geoproducts play in geotourism. The research method used is qualitative and descriptive using primary and secondary data. The SMEs in Belitong are located around the geopark's buffer zone. The result of this study shows that geoproduct varied in terms of the nature of the product, and quality. Most of the products are culinary and handicraft product using local grown ingredients and indigenous knowledge. The proposed strategy for developing a variety of geoproducts is a global value chain strategy that helps producers compete in marketing their product at geotourism site.
Tujuan dari penelitian ini adalah memahami perilaku wisatawan dalam fungsi interaksi di suatu destinasi pariwisata khususnya kepariwisataan di Indonesia dengan menggunakan metode bibliometric study atau dengan metode penelitian dari data sekunder. Hasil dari penelitian ini menunjukkan bahwa interpretasi yang baik akan sangat mempengaruhi suatu destinasi dan calon wisatawan yang akan mengunjunginya. Semakin tinggi nilai tambah suatu destinasi yang ditawarkan kemudian ditambah interpretasi yang baik maka semakin menarik calon wisatawan untuk melakukan perjalanan, khususnya Nature-Based Tourismyang sejatinya memiliki banyak hal untuk dipelajari oleh wisatawan.
Rancaekek and Sayang, West Java, are the area where many industrial factories are located. Thus, the region becomes the targeted destination for industrial development. The population in the area is rising due to the growth of industries causing the regional development becomes uncontrollable. In addition, the constant increment of waste and also poor-coordinated disposal systems may result in groundwater contamination in the areas. The rapid growth of the area increases the need for groundwater as well as the need for more research about contamination at Rancaekek and Sayang. The research aims to explore the spread of groundwater contamination in the area. The research method is carried out based on the analysis of Geological Mapping, Hydrogeological Mapping and chemical characteristics of the groundwater in the area. Chemical analyses of the groundwater were conducted through laboratory test of groundwater samples at specific spots of dug wells. The lab test results were further analyzed to determine the contamination zone. The findings reveal that the distribution of contamination in the area follow the shallow groundwater flow patterns, the water contamination contains heavy metal and there is degradation of soil fertility. The findings suggest the stakeholders delineate the contaminated area, and increase the dissemination of environmental awareness.
Indonesia is known as rich in natural resources due to its location in the ring of fire and meeting of three continental plates. There are two international geopark recognized by Global Geopark Network UNESCO, which are Batur Global Geopark dan Sewu Global Geopark. The geopark contains Indonesia's geotourism resources explored in this study through the perception of management. Competition for geotourism destination to attract tourists is high, since other neighboring countries also have offered geotourism. The objective of this study is to explore the geotourism resources in geopark, and how it is linked to sustainable development. Research utilize qualitative method, collecting secondary data and primary data through interview guided with semi-structured questionnaires with two geopark management organization about 10 geopark personnel and 100 tourists. The results found that respondents have perceived geotourism resources in the geopark to be rich and diversified, but lack in conservation, interpretation, resources management and needs further development based on the sustainability principle. Recommendation is suggested to the stakeholder such as geopark management, government, community, and academics for more coordination and collaboration to ensure geotourism resources play a role in sustainable development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
