Abstract

Pertumbuhan ekonomi yang tinggi di Jakarta diiringi dengan pertambahan jumlah penduduk dan pembangunan infrastruktur yang semakin padat. Tingginya tingkat pembangunan infrastruktur di Jakarta menyebabkan semakin berkurangnya tutupan vegetasi dan terganggunya fungsi alami ekosistem yang semula ada di Jakarta, seperti fungsi sistem hidrologi. Pembangunan fisik dan infrastruktur di daerah perkotaan seharusnya diimbangi dengan pengelolaan lingkungan yang seimbang sehingga dampak negatif yang timbul dapat diminimalkan. Salah satu bentuk pengelolaan lingkungan dapat dilakukan dengan pengaturan dan pemanfaatan ruang yang optimal sehingga fungsi ekosistem tetap terjaga. Studi ini bertujuan untuk menganalisis bagaimana hubungan perubahan tutupan lahan terhadap sistem hidrologi yang dilihat dari persediaan air dan fenomena banjir di Jakarta, serta menyiapkan rekomendasi untuk perencanaan ruang berbasis sistem hidrologi. Analisis dilakukan secara kuantitatif dengan bantuan Sistem Informasi Geografis, berdasarkan data sekunder dan studi literatur. Berdasarkan pengolahan citra Landsat tahun 1999-2019, terjadi perubahan tutupan lahan dimana tutupan lahan vegetasi di Jakarta mengalami penurunan dari 35,5% menjadi 6,4%, sementara luas lahan terbangun terus mengalami peningkatan dari 65,5% menjadi 93,6%. Kepadatan bangunan di Jakarta menyebabkan peningkatan luas permukaan tanah yang bersifat impervious sehingga terjadi peningkatan laju aliran air permukaan dan penurunan laju aliran dasar di bawah tanah sehingga memicu terjadinya banjir.

Abstract

Sand mining in Keningar village, which has been started since 1996, is still carried out by the community to date, even though the damage is already exist and severe. The community start to dredge the crop land to take the sand, then sell it. Sand mining activities are not only carried out by the residents of Keningar village, but also by another parties from outside the region. The change of land use from crop land into sand mining areas has many impact on various aspects of community life, both on social, economic and cultural aspects. The purposes of this study are to know the perspective of the community of Keningar village on sand mining activities that has been carried out to date, their effect for the environment, and social life patterns of the community of Keningar village. This study use qualitative method by describe all the information. The information was obtained from observations and unstructured interviews with several informants found at the site. The results of the study show that there is a social change in the community of Keningar village, caused by a paradigm shift from farmers to sand miners. The driving force for this phenomenon is economic factor, the demand for everyone needs are high. This paradigm shift has many effects not only on socioeconomic, but also for the environment. Massive exploitation of sand, gravel, and rocks cause the lost of fertile layers of soil and reduce groundwater reserves on community’s crop land. The sand mining can be controlled since the government applied mining license instrument. However, there is still illegal mining carried out between the landowners and mining entrepreneurs by simple agreement. In reality, the indigenous character of the community of Keningar village is farmers and charatcter of “nrimo ing pandum” which actually can be developed to an advance economy without damaging the environment, through the intervention of the government, academics, or other stakeholdes. And one of them can be solved through education.
