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

Background: Indonesia has the potential of natural resources to support agriculture. However, there are still some areas that have not optimized natural resources. People focus on planting commodity crops without considering the physical conditions of the environment and socio-culture. This research aims to develop policy directions for agricultural priority areas that consider the physical conditions of the environment and their suitability for farmers' commodity preferences. Methods: This study uses a quantitative approach with a combined method to determine agricultural priority areas. It integrates ZAE analysis, land carrying capacity, and farmers' commodity preferences. Findings: The results showed that the commodities preferred by farmers were cocoa, corn, and upland rice. The preference for these commodities has a significant correlation, especially with the source of income and the size of cultivated land. There is a 51% mismatch of existing agricultural land with the ZAE while in general agriculture in Nangapanda is in accordance with the carrying capacity of the land because it is at a high level of carrying capacity. Conclusion: Based on the agricultural priority areas formed, agriculture in Nangapanda can utilize dry land mainly for plantations with the direction of the main commodities tailored to the physical conditions of the land and the preferences of farmers namely cocoa, cashew, cloves, nutmeg, pepper. Novelty/Originality of this article: The novelty of this research lies in the integrative approach in formulating agricultural priority area policies that combine the suitability of physical environmental conditions and farmers' commodity preferences, which has not been widely applied in similar studies.
