Perubahan lingkungan di wilayah pesisir teluk Jakarta akan berpengaruh pada kualitas lingkungan perairan di Teluk Jakarta. Hal tersebut akan terekam oleh inti bor sediment yang terdapat di Teluk Jakarta. Penelitian ini merupakan penelitian pendahuluan yang bertujuan untuk meneliti perubahan pola sedimentologi dari conto inti bor sedimen dari teluk Jakarta. Dalam studi pendahuluan ini dilakukan analisis LOI untuk mengetahui kadar material organik dan juga analisis mikropaleontologi Hasil analisis pada Bor GC 21 menunjukkan adanya korelasi yang baik antara peningkatan kadar material organic dan penurunan kadar karbonat dengan perubahan kandungan fosil. Meningkatnya kandungan foraminifera plankton pada kedalaman 13-14 cm diikuti menghilangnya ostracoda pada kedalaman 12-13 cm kemungkinan berkaitan dengan letusan Krakatau 1883. Kata Kunci : sedimen, inti bor, lingkungan, Teluk Jakarta. The environtmental changes around Jakarta coastal area will influence the environmental quality of Jakarta bay waters. Marine sediment core in the Jakarta bay will records these changes. This preliminary research will study the sedimentology pattern of marine sediment located at Jakarta bay. In this study LOI sediment core will be analysed for LOI and micropaleontology. The result from core GC 21 shows that increasing material organic content coincide with decreasing the content of carbonate and microfossil. Increasing foraminifera plankton at 13-14 cm depth coincide with disappearance of ostracode at 12-13 depth, this suppose that related to the Krakatau eruption on 1883. However the further research is still required to convince the result. Keywords : sediment, core bor, environment, Jakarta Bay

The latest trends in tourism indicate the emergence of a new segment of visitors looking for accommodation in private residences. The increase in second-home residents has led to efforts to improve knowledge of the preferences of this new type of tourist in those destinations where their presence is considerable. As one of the key variables affecting the choice of residential tourists is the environmental quality of the area, this paper focuses on testing for the existence of an inverse correlation between the loss of coastal water transparency, viewed as a measure of environmental quality, and beach aesthetics in Santa Ponça Bay, a Mallorcan coastal area containing two urban beach zones of intensive recreational use, where the proportion of second-home residents is high. The results show that the willingness to pay for improvements in water transparency diminishes in a non-linear way when transparency deteriorates, resulting in no statistically significant differences between first- and second-home residents.

The coastal area of Semarang City has a strategic function for regional economic development. Due to land use change, the environmental quality of coastal area is damaged and declining. The environmental quality decline has affected the socio-economic quality of local community. This research aims to investigate the role of local community in sustainable environmental management in Semarang City coastal area. The study takes place in two kelurahans, namely Tugurejo and Mangunharjo, and applies a descriptive qualitative approach to figure out the local community role in the coastal environment rehabilitation. Data collection through a preliminary survey supported with a satellite imagery study covers up an appropriate ecosystem with the research substance. Then the following data analysis and interpretation uses Miles and Huberman interactive analysis method. The results show the significant role of the local community in coastal area quality management and improvement in Semarang City more effectively and efficiently. This relates to their active interactions in various community-based programs including wave-breaking instrument building and mangrove nursery and planting.
