Abstract

The hinterland of Jakarta has experienced high pressure in its land utilization due to Jakarta’s rapid development. The objective of this research was to analyse the suitable land available for agriculture. The research was conducted in Bogor, a hinterland regency of Jakarta. The methodology used includes two steps of analysis, which are land suitability and land availability analysis. Land suitability for agriculture was analysed using multi-criteria decision making method. Seven (7) criteria were included, which consist of soil class, land capability class, slope, elevation, slope aspect, land use/land cover and distance to roads. The criteria were weighted using the Analytical Hierarchy Process. Combining criteria weights and sub-criteria scores, an overlay model in Geographic Information System was applied. The result from land suitability analysis was used as a feed for determining land availability, considering the forest area status and land allocation in the official spatial land use plan. The results indicate that an area amounting to 87.5% of Bogor Regency is suitable for agriculture. Land which is suitable and available for agriculture is 16.7% of the regency’s area. Considering available land which is currently in use, the area that can be allocated for the expansion of agriculture is 3.3%.

Abstract

Pemantauan karakteristik air laut di Selat Lombok sangat penting karena merupakan jalur pelayaran yang sibuk. Sejak 1 Juli 2020, Indonesia berwenang mengatur alur pelayaran menggunakan Traffic Separation Scheme (TSS). Banyak faktor yang mempengaruhi kondisi iklim di Selat Lombok, diantaranya adalah angin muson yang menyebabkan kecepatan dan arah arus berbeda. Tujuan dari penelitian ini adalah untuk mengidentifikasi karakteristik arus di Selat Lombok, menganalisis data Automatic Identification System (AIS) di kawasan tersebut, dan menganalisis pengaruh arus laut terhadap kecepatan dan arah kapal. Data arus laut yang bersumber dari Marine Copernicus dengan periode satu tahun (Oktober 2020 – September 2021) digunakan untuk menganalisis pola dan karakteristik arus. Data kecepatan dan jenis kapal diperoleh dengan menggunakan data AIS yang bersumber dari vessel finder. Dilakukan analisis overlay data arus dan lalu lintas laut, kemudian geovisualisasi data diimplementasikan dengan menggunakan software ODV. Sedangkan simulasi data kapal dan arus menggunakan Statfit dan Promodel. Hasil penelitian menunjukkan bahwa pergerakan arus sangat dipengaruhi oleh periode monsun, dimana kecepatan arus yang kuat terjadi pada musim barat dengan periode yang lebih singkat dibandingkan musim lainnya. Kecepatan dan arah arus mempunyai peranan dalam mengubah kecepatan kapal, yang kemudian dapat menjadi bahan pertimbangan dalam menentukan jadwal dan rute kapal demi alasan keamanan dan keselamatan transportasi.

Abstract

Access to food is a human right. The destruction of paddy fields due to changes in use in various regions in Indonesia affects the national food supply. The contribution of domestic rice is decreasing, and the dependence on imported rice is increasing. In the long term, this phenomenon will threaten efforts to fulfil the adequacy of the staple food rice for the growing population, thereby increasing the potential for a food crisis. This study analyses the decline in domestic rice sufficiency due to the destruction of paddy fields in Banyumas Regency, Central Java Province. The method used in this study is mixed, consisting of visual image interpretation, map overlay, and descriptive quantitative analysis. The results showed that the average rate of destruction of paddy fields in Banyumas Regency from 2007 to 2019 was 102.6 hectares per year, concentrated around Purwokerto District, which is the capital of Banyumas Regency . The potential loss of rice production is 1,189,580 kilograms per year of harvested dry grain, equivalent to IDR 5,709,984,000.00.
