Population growthis linear tothe requrement of settlement area, while the area of the earth is limited. It was caused inappropriate use of the land. This study aims to identify, analyze, and describe dynamics and suitability of land for settlements in Padang. Determination of land suitablity for settlementis using Multi Criteria Evaluation (MCE) method. The indicators used in determining the suitability of land for settlement is the slope, the frequency of flooding, drainage, distrubusi gravel, rock distribution and effective depth. Weighting in the analysis of land suitability based on the opinions of experts from various fields related to as many as 15 experts. Analysis result for land suitability of settlements in the area show that: there were 12.543 ha (18%) very suitable for settlement; 52.390 ha (75,4%) were suitable for settletment; 4.279 ha (6,2%).were compatible with marginal for settlement; and 285 ha (0,8%) were unsuitable for settlement. The area is very suitable for residential areas is very limited, so expect optimal utilization.
Abstract. Sadikin PN, Arifin HS, Pramudya B, Mulatsih S. 2017. Carrying capacity to preserve biodiversity on ecotourism in Mount Rinjani National Park,. Mount Rinjani National Park (MRNP) in West Nusa Tenggara, Indonesia has applied ecotourism which becomes more popular at international and national level. Yet, the MRNP ecotourism faces various problems such as ecotourism resources damage, erosion, or garbage left by ecotourism activities, etc. This study aims to analyze (i) the land suitability for ecotourism based on criteria of tourism object range, land use and land cover, zone type, biodiversity range, and slope, and (ii) carrying capacity of the ecotourism area, the total number of visitors who can enjoy ecotourism attraction based on activities type, total area, capacity days, and turnover factor. The results of the land suitability for ecotourism analysis show that the MRNP ecotourism has been applied on the suitable land for ecotourism, except in Pelawangan Senaru and at the Peak of Mount Rinjani due to its sensitive and fragile area. The carrying capacity assessment using Douglass formula (1982) has counted the visitors for up to 42.527 visitors per year for camping activity. Generally, this value is under the average actual visitors at present, i.e. 44.112 visitors per year. It means the MRNP ecotourism is already exceeded its carrying capacity.
It is estimated that 13% or 62 of 470 watersheds in Indonesia are in critical condition, although soil and water conservation in watershed management has long been implemented. Ciliwung is one of the critical watershed. This research was conducted in the upper Ciliwung watershed, Bogor Regency. The purpose of this research were (1) to determine the sustainability index of upper Ciliwung watershed management, (2) to identify important factors that determine the sustainability index of upper Ciliwung, and (3) formulating development policies for upper Ciliwung sustainable watershed management. Multidimensional scaling (MDS) analysis is used to assess the sustainability index of watershed management. Analysis of leverage is used to determine the important factors. Prospective analysis was used to formulate the development of sustainable watershed management policy. The results showed that the status of watershed management of upper Ciliwung was less sustainable. The strategy of watershed management policy should be developed through performance improvement intervention scenarios covering the key factors : (1) coordination capacity of government agencies, (2) utilization of tourist services, (3) farmers' income from non-agricultural activities, (4) extension activities of agriculture and forestry development, and (5) avoid inapropriate landuse conversion.
Revitalization of agriculture is basically putting back the importance of agriculture proportionally and urban contextual in both rural and urban areas. Considering the existing condition of agriculture in urban areas, especially Jakarta Province, and linkages with its various environmental problems, it is expected that the development of agriculture would not be sustainable. Thus, it needs designation and formulation of a comprehensive policy for sustainable development of urban agriculture. The study is aimed to analyze the sustainability of urban agriculture as well as the critical factors affecting the sustainability and policy of urban agriculture development. The methods of MDS (multi-dimensional scaling) and Rap-Ur-Agri (Rapid Appraisal for Urban Agriculture) technique are employed for analysis. Meanwhile, key factor analysis uses leverage factor followed by determination of sustainable indices, and policy scenarios that use a prospective analysis method. The results show that the sustainability status of agricultural development on the existing condition of urban areas has an index value of 48.70 percent (i.e., less sustainable). The urban agriculture has four sustainability key factors, while attributes of stakeholders' needs have also four key factors. These eight key factors are merged yielding six key factors that influence the development of urban agricultural systems. Policy for sustainable urban agricultural development of Jakarta Province has to use an integrative approach with consideration of six key factors of agricultural sustainability, namely: (1) Yard acreage, (2) The development of commodity and environmentally sound technology, (3) Extension and agricultural institutions, (4) Availability of land area, (5) Cooperation among stakeholders, and (6) Provision of agricultural incentives. Policy options would encompass extension of land and space for farming, commodities and environmentally-friendly technology development, and agricultural institutional development. Key words: agricultural policy, urban agriculture, sustainable, development ABSTRAKRevitalisasi sektor pertanian pada dasarnya adalah menempatkan kembali arti pentingnya pertanian secara proporsional dan kontekstual, baik di perdesaan maupun perkotaan. Melihat kondisi pertanian di daerah perkotaan, khususnya DKI Jakarta, dan hubungannya dengan berbagai masalah lingkungan, perlu dirancang dan dirumuskan kebijakan yang komprehensif untuk pengembangan pertanian perkotaan berkelanjutan. Penelitian ini bertujuan menganalisis faktor-faktor kunci yang mempengaruhi keberlanjutan dan kebijakan pengembangan pertanian perkotaan. Metode analisis yang digunakan adalah MDS (multidimensional scaling) dan teknik Rap-Ur-Agri (Rapid Appraisal for Urban Agriculture). Analisis faktor kunci menggunakan leverage factor yang diikuti dengan penentuan indeks keberkelanjutan dan skenario kebijakan pengembangan pertanian dengan menggunakan metode analisis prospektif. Hasil analisis menunjukkan bahwa status keberlanjutan pengembangan pertanian perkota...
