One of the agricultural public commodities in Indonesia which still cannot fulfill its domestic consumption needs is soybean. The objectives of the research, which was conducted in Karawang Regency, West Java, Indonesia, were to: (i) identify the suitable area for soybean plantations in paddy fields, (ii) Â assess the development of soybeans in land use and socio-economic context, and (iii) plan the spatially soybean plantation. A soil survey and land evaluation for soybean was completed. IKONOS imagery was applied to delineate paddy fields while a dynamic system modelling was developed using Powersim 8.0 software. The results of the research showed that the suitability class for soybean plantation in the paddy fields of Karawang Regency ranges from unsuitable (N) to suitable (S2), with limiting factors being temperature, fertility, nutrients retention, slope, erosion, rooting media and toxicity. Very limited arable land Â has been used so far for soybeans plantations due to low economic returns. The model predicts that, should the development of soybean continues in its business as usual path, a deficit of soybean will occur in 2030. The model provides alternative scenarios to reduce the deficit. Prioritization was done spatially using the suitable land gradually, corresponding to the government budget availability.

Indonesian national food sovereignty is very dependent on the supply of rice from paddy fields in Java Island. Various factors influence the farmerâs decision to continue using his farm. This study aims to analyze the sustainable use of paddy field, determinant factors and strategies for improving sustainability. The study was conducted in Karawang Regency, one of the centers of rice production in West Java. The methodology used is a multi-dimensional scaling (MDS) using 43 attributes of 5 dimensions (ecological, social, economical, technological and legal and institutional dimension). Against the sensitive attribute analysis resulting from MDS, a prospective analysis was conducted to determine the key factors of sustainability. Priority policies for improving sustainability are developed based on the location of the key factors in the prospective diagram. The research results showed that the land utilization for paddy field in Karawang is actually less sustainable. Increasing the sustainability can be done through intervention and improving performance, preferably on sensitive attributes resulting from leverage analysis, covering 16 attributes. Priority policies is directed in the 5 key factors resulting from prospective analysis. Policies suggested are the tightening of new permits for building, strict implementation of the official spatial land use planning and delineation of agricultural land for sustainable food crops, counseling the community, revitalizing the role of BULOG, provision of subsidies as well as capital assistance to farmers.

Abstract. The availability of light in the water column determines the euphotic zone and constrains the type and the vertical distribution of benthic species. Diffuse attenuation coefficient (Kd) is an important apparent optical property (AOP) that provide information about the attenuation of the spectral down welling solar irradiance with depth in the water. Ocean color Satellite provide global coverage of optical water quality parameters at spatial and temporal resolution. Several empirical and semi-analytical models are commonly used to derive Kd at wavelength 490 nm Kd(490) from ocean colour satellite sensors. This study present about the diffuse attenuation coefficient, Kd(490) using semi-analytical approach. The dynamic Kd(490) in the Berau Estuary water was studied and compared with those derived from ocean color satellite sensor, Medium Resolution Imaging Spectrometer (MERIS). The study indicated that Kd(490) of in situ measurement had the best correlation with the Kd(490) of MERIS data of remote sensing reflectance (Rrs) derived with FUB (Free University Berlin) algorithm (R2=0,84). The dynamic of Kd(490) from MERIS data on different date indicated that the Kd(490) have a similar pattern and decreased when going to offshore.Â Keywords: MERIS, Secchi disc depth, tropical coastal water, Kd(490), a semi-analytical approach

Sumberdaya lahan di Indonesia sangat beragam, dengan tingkat kesesuaian lahan untuk berbagai komoditas yang beragam pula. Karena itu, diperlukan perencanaan penggunaan lahan âtermasuk di lahan-lahan daerah transmigrasi- untuk menjamin pola budidaya yang paling sesuai secara fisik dan memberikan hasil yang optimal secara ekonomis. Evaluasi lahan merupakan salah satu cara untuk mengidentifikasi komoditas yang paling cocok untuk diushakan. Penelitian ini bertujuan untuk melakukan evaluasi lahan fisik dan ekonomik di lokasi transmigrasi Rantau Pandan SP-2, Provinsi Jambi menggunakan sistem evaluasi lahan otomatis (Automated Land Evaluation System (ALES). Hasil evaluasi kemudian digunakan untuk merekomendasikan penggunaan lahan yang paling sesuai secara fisik maupun ekonomik di lokasi transmigrasi lahan kering. Hasil studi menunjukkan bahwa dominasi kelas kesesuaian lahan untuk 9 (sembilan) komoditi adalah S3. Pembatas yang paling dominan adalah bahaya erosi dan retensi hara. Pembatas yang dominan pada kesesuaian lahan adalah bahaya erosi, ketersediaan air dan temperatur. Hasil evaluasi lahan ekonomi menunjukkan bahwa secara umum komoditas yang paling menguntungkan untuk diusahakan pada kesesuaian lahan ini adalah tomat. Rekomendasi yang diberikan berdasarkan hasil analisis tidak selalu sejalan dengan peruntukan lahan pada pola transmigrasi lahan kering. Meskipun demikian, hasil ini disarankan untuk diterapkan, baik dengan pertimbangan konservasi lahan maupun pertimbangan keuntungan ekonomi dan kesejahteraan petani.Kata Kunci: Kesesuaian lahan, pemetaan, pertanian lahan kering, transmigrasiABSTRACTLand resources in Indonesia are highly variable in the term of their suitability to support the cultivation of commodities. To that end, landuse planning -including in transmigration area- is needed to ensure the utilization of the most appropriate pattern of cultivation, which gives the highest yield biophysically, and economically profitable. Land evaluation is a method to identify the suitability of land for various use. This study aimed to physically and economically evaluate land suitability of transmigration settlement units for different commodities by using Automated Land Evaluation System (ALES). The evaluation results are then used to recommend the most appropriate commodity, either physically and economically, on dry land transmigration site. The study was conducted in Rantau Pandan SP-2, Jambi Province.This studyintegratedArc-View GIS with ALES and expert knowledgein land suitability analysis. The results showed that in the nineobserved agricultural commodities, the land suitability dominant class isS3 (marginally suitable), with erosion and nutrient retention as the most dominant limiting factors. Recommendations weregiven based on the analysis results, which were not always in line with the pattern of land use on dry land transmigration. Nonetheless, these results are suggested to be applied, either byconsidering land conservationor considering economic benefit and welfare of the farmers.Keywords: Land suitability, mapping, dryland farming, transmigration site

Abstract. The level of regional developmentÂ is marked by high availability of public facilities, such asÂ education, health, economic, social facilities and their accessibility. A higher of index of public facility availability means a region can support human activities well, including the economic sector. Spatial patternsÂ ofÂ public facility availability in Cianjur Regency wereÂ analized by global and local spatial autocorrelationÂ based on the Moranâs index and the local indicator spatial association (LISA) index, respectively. A spatial weighted matrix (wij) for MoranâI and LISAÂ calculated based on nearest neighbor, neighbor boundary length and neighbor distance. The result showed that differences in the spatial weighted matrix of MoranâsÂ index does not affect the spatial pattern but they do affect the Moranâs I values for nearest neighbor, neighbor boundary length and neighbor distance, at 0.30; 0.22 and 0.33, respectively. Differences in the spatial weighted matrix of LISA index showed that 97% of districts have the same scatter plot and only 3% of districts have different scatter plot. The spatial pattern type of public facility evailability in Cianjur Regency is cluster whereÂ the nothern Cianjur cluster is in HH category and the central-southern Cianjur cluster is in the LL category.Keywords.

ABSTRAKKeputusan Presiden No 32/1990 menyatakan bahwa sempadan sungai adalah kawasan perlindungan setempat. Pelestarian kawasan sempadan ini juga didukung oleh peraturan lainnya. Meskipun demikian, berbagai pelanggaran terhadap peraturan perundangan terus terjadi, termasuk banyaknya permukiman ilegal di kawasan sempadan Ciliwung yang memunculkan bahaya lingkungan. Oleh karena itu langkah pencegahan perlu segera ditempuh. Model perumusan kebijakan pengelolaan lanskap dirancang untuk dapat mengatasi hal ini melalui dukungan analisis spasial kemampuan lahan dan kesesuaiannya. Tujuan dari penelitian ini adalah untuk menganalisis kemampuan lahan dan kesesuaiannya untuk beberapa tanaman guna mendukung program penghijauan di kawasan sempadan Ciliwung. Evaluasi lahan dilakukan melalui analisis Satuan Peta Lahan (SPL). Kawasan sempadan Ciliwung di Kota Bogor ini terbagi menjadi 18 SPL. Analisis spasial yang dilakukan berdasarkan data tahun 2006-2013, menunjukkan terjadinya peningkatan permukiman ilegal sebesar 0,8% dan tingkat pengurangan luas ruang terbuka hijau sebesar 0,17%. Hasil analisis kemampuan lahan menunjukkan bahwa 85,78% dari total luas lahan memiliki kemampuan sedang hingga tinggi (kelas II-e, II-w, III dan IV-e). Kelas kemampuan lahan II-IV direkomendasikan untuk lahan pertanian, sedangkan kelas V-VII direkomendasikan sebagai lahan konservasi. Berdasarkan analisis kesesuaian lahan, daerah ini memiliki potensi kesesuaian lahan untuk jenis tanaman budidaya, khususnya buah-buahan. Hasil ini dapat menjadi alat yang kuat untuk merumuskan kebijakan pengelolaan lanskap di sempadan Sungai Ciliwung di Kota Bogor.Kata Kunci: evaluasi lahan, kemampuan lahan, kesesuaian lahan, manajemen lanskap, penghijauan, kebijakanABSTRACTAccording to the Presidential Decree No. 32/1990, riparian area is among locally protected areas. Other government regulations strongly recommend on conservation of the riparian area. Typically, continuous violation of governmental regulation is noted mainly illegal settlements in the Ciliwung riparian area, which led to environmental hazards. Hence preventive major should be taken in this regard. A policy formulation model of landscape management can be designed through spatial analysis of land capability and land suitability. The aim of this research is to analyze land capability and suitability for re-greening program in the Ciliwung riparian area. Land evaluation is carried out through analysis of soil map units (SPL), which are divided into 18 SPL, followed by land capability and suitability analysis. Results of spatial analyzes based on data year 2006-2013 showed a rate of increase in illegal settlement area by 0.8% and a rate of reduction in green open space area by 0.17%. The result of land capability analysis shows that the total area is approximately 85.78% has moderate to high land capability (class II-e, II-w, III-e and IV-e). The land capability classes II-IV are recommended for agricultural land, while classes V-VII are recommended for conservation area. Based on land suitability analysis, this area has potential for local crops. These results can be strong tools for formulating a landscape management policy for Ciliwung riparian area in Bogor City.Keywords: land evaluation, land capability, land suitability, landscape management, re-greening, policy
