Abstract

The wetland has a strategic role in national development. The potential uses of the wetland are varied such as for agriculture, fisheries, industries, and forestry. The intensive use of the wetland for agricultural development in Sumatera, Kalimantan, Sulawesi, and Papua through transmigration projects has been run since in 1973. Unfortunately, not all the projects were well developed, causing the social, economic, and physical environmental problems. These problems resulted in the negative impact for the life of the transmigration people. For that reason, the community empowerment for the unlucky transmigration people by handling the physical and non physical aspects is very important. This paper will describe the importance of providing spatial data and information biophysical wetland as an initial step in empowering people who live in the wetland resource.

Abstract

Planning analysis to increase rice production either through intensiḀcation of existing paddy Ḁeld area or ex-tensiḀcation in potential land area was conducted in West Lombok Regency, West Nusa Tenggara Province, Indonesia. Existing paddy Ḁeld was delineated using high-resolution data from IKONOS imagery of 2012. Land use and land cover outside existing paddy Ḁeld were interpreted using SPOT-5 imagery of 2012. ἀe Automated Land Evaluation System (ALES) was used for land suitability analysis for paddy. ἀe results are interpreted in terms of the potential of paddy Ḁeld intensiḀcation in existing paddy Ḁeld area and the potential of extensiḀcation in land potentially used for paddy Ḁeld. ἀe result of analysis showed that in West Lombok Regency, there are still possible to do intensiḀcation and extensiḀca-tion of paddy Ḁeld to increase rice production in order to improve regional food security.

Abstract

Pemanfaatan data survei tanah dan evaluasi lahan dilakukan untuk perencanaan peningkatan produksi kedelai menjawab tantangan kelangkaan pasokan kedelai di Kab. Lombok Timur, Provinsi Nusa Tenggara Barat. Data yang digunakan adalah hasil survei oleh Pusat Pemetaan dan Integrasi Tematik, Badan Informasi Geospasial dilengkapi dengan analisis citra dan evaluasi lahan fisik dan ekonomi untuk kedelai. Analisis kesesuaian lahan fisik dan ekonomi untuk kedelai dilakukan menggunakan Automated Land Evaluation System (ALES). Penggunaan lahan diinterpretasi menggunakan citra SPOT-5, dipertajam dengan data lebih detil menggunakan citra IKONOS dari Kementerian Pertanian. Hasil-hasil analisis diinterpretasi dalam term potensi intensifikasi kedelai pada lahan sawah eksisting dan potensi perluasan tanaman kedelai pada lahan kering yang potensial. Hasil analisis menunjukkan bahwa di wilayah Kabupaten Lombok Timur masih dimungkinkan dilakukan intensifikasi dan ekstensifikasi untuk peningkatan produksi kedelai dalam rangka peningkatan ketahanan pangan regional. Persoalannya, keuntungan petani dalam budidaya kedelai pada berbagai kelas kesesuaian lahan jauh lebih kecil dibandingkan pengusahaan padi sawah. Perencanaan fisik berbasis kesesuaian lahan perlu diikuti dengan upaya menciptakan kondisi agar penanaman kedelai menarik bagi petani dari sisi ekonomi.Kata Kunci: Ketahanan Pangan, SPOT-5, Kesesuaian Lahan, Sistem Evaluasi Lahan Otomatis.ABSTRACTData from soil survey and land evaluation were used in planning for increasing  soybean production, answering the lack of soybean supply in East Lombok Regency, West Nusa Tenggara Province. The results of the survey of Center for Integrated Mapping, Geospatial Information Agency were used, combined with image analysis and physical and economical land suitability analysis for soybeans. Analysis of physical and economical land suitability for soybean was performed using Automated Land Evaluation System (ALES). Land use was interpreted using SPOT-5 imagery, completed by the data of IKONOS imagery from Ministry of Agriculture. The results of the analysis were interpreted in terms of the potential intensification of soybean on existing ricefield and the potential expansion of soybean crops ondry land. The analysis showed that in East Lombok Regency, there is still possible to do the intensification and extension of soybean in order to improve regional food security. The problem is, benefit of farmers in the cultivation of soybeans in various land suitability classes are much smaller than rice cultivation. Physical planning based on land suitability needs to be coupled with efforts to create an attractive situation to farmers for planting soybean.Keywords: Food Security, SPOT-5, Land Suitability, Automated Land Evaluation System.

Abstract

The environmental  damage in Kabupaten Bandung is critical. To solve the environmental problems,  the integrated spatial data of the physical environment is required.   Land system data as  the integrated spatial data which describes the characteristics of land are useful for the analysis and  evaluation of the environmental conditions. The objective of the study is to describe the characteristics of the physical environment of Kabupaten Bandung based on the land system map  for the input of  decision-making in achieving  sustainable development. The study used the spatial analysis and descriptive analytical method. The land system data was obtained  from the Badan Informasi Geospaasial (BIG). The results show that the landforms in Kabupaten Bandung are dominated by volcanic and fluvial landforms. The volcanic landforms has morphology dominated by mountainous areas with the slope steepness more than 45% and  the soil types of andosols. The land capability of these mountainous areas belongs to grade 7 (for conservation areas). The fluvial landforms are lacustrine plains, which are prone to flood due to inundation.  From this study, it is concluded that the land utilization in Kabupaten Bandung, particularly in mountainous areas, is not in accordance with the land  carrying capacity. To achieve the sustainable development, the land utilization should consider the regulation of spatial planning, by which the lands with slope steepness more than 40% are categorized as protected areas.   Keywords: Land system, land characteristics, landform, suistanable development
