Abstract

Spatial as a contributor to biological productivity and ecosystem services have not been considered in the sustainable development of small islands. The aim of this study to appraise biocapacity (BC) in the Gili Matra Islands to estimate the existing carrying capacity for sustainable development, and refines the current BC methodology that emphasizes the spatial aspects in small islands. Based on analysis results, the Gili Matra Islands have BC total ranging from 659.46 to 1,069.57 gha in 2010, and increased from 673.64 to 1,093.02 gha in 2014. The highest total BC is the Gili Trawangan Island, while the lowest is the Gili Meno Island, but for the local BC is the opposite. The total local BC per island can be supplied around 0.00857 gha per capita for the Gili Ayer Island, 0.20103 gha per capita for the Gili Meno Island, and 0.00344 gha per capita for the Gili Trawangan Island. They are influenced by population density. The BC values indicate a critical position, both per-unit-area or per-capita, which is spatially nearly 100 % of the needs supplied from outside the island, and demonstrate the use on the Gili Matra Region have exceeded the existing carrying capacity. The sustainable development aspects and land use management should be applied strictly to ensure the sustainability of natural resources, social and economic, as well as cotinuously consider the efforts and existing strategies of conservation. The export and import factors of bioproductivity should be considered in making long-term planning. Spatially, BC appraisal was applicable to illustrate the condition of an area on the small islands. The GIS based BC can give the information of pattern of changes and distributions, both spatial and temporal. However, the statistical data use is needed to get the value of BC per capita.

Abstract

The mangrove ecosystem in Ujung Pangkah Sub-district Gresik District has an important role in living life in the delta of Bengawan Solo River. The existence of mangrove ecosystem in this sub-district is threatened by land conversion activity, especially land conversion of mangrove forest to fishpond. In addition, sedimentation activities in the Solo River led to the formation of new land in the mouth of the river that formed the mudflat. This location is an important habitat for flora and fauna. The existence of mangrove forests and emerging lands is threatened by land conversion activities into ponds. The degradation condition of mangrove ecosystem in this research is coastal change in the form of abrasion and reduction of mangrove forest area determined by spatial approach with Geographic Information System application and remote sensing. Damage to mangrove ecosystem in the period 2006 to 2016 in the form of abrasion is 177.64 hectares, while the reduction of mangrove forest area in the same period of 101.70 hectares.Key words: Geographic Information System, remote sensing, Gresik, Bengawan Solo River

Abstract

ABSTRACT The limited scientific information and lack of attention from stakeholders on the status of mangroves in Kembung River functioned as a basis of this study. Four series of Landsat data recorded in 1996, 2002, 2010, and 2013 were used to map mangrove land cover and changes detection. Hybrid classification technique, a combination of the object-based and random forest classifications, were applied in this study. The result showed that based on hybrid classification, mangrove coverage was detected within 82.6-88.4% overall accuracy. Change detection analyses showed that the mangrove area of Kembung River was relatively stable. For nearly two decades, we found mangrove loss about 197.2 ha, gain of 251.1 ha, and unchanged of 2904.9 ha. Changes in mangrove were generally caused by anthropogenic factors such as mangrove replanting, logging, changes over the function of mangroves into the road, embankment, settlement, shrimp farms, and natural growth. Serious attention from various parties are needed to maintain the existence and sustainablility of mangrove ecosystems in Kembung River.   Keywords: Mangrove, Sungai Kembung, monitoring, Landsat, hybrid classification

Abstract

Mangrove rehabilitation has implications for important ecological, social and economic values for coastal communities. The mangroves ecosystem Karawang Regency is still under pressure due to the management and utilization that does not pay attention to the sustainability aspect. The rehabilitation plan to mangrove management must be adapted to the nature and characteristics of the habitat. This study aims to formulate technical considerations for the direction of a rehabilitation plan based on an ecological approach and the dynamics of the mangrove ecosystem. The methods used in this study were geospatial approach that integrated with field quanitative and qualitative data. The results show that the total of mangrove potential area in Karawang Regency was 19,139.53 ha, consisting of 421.95 ha (2.2%) of vegetated area and 18,717.58 ha (97.8%) of unvegetated area. We integrate mangrove typology, mangrove stand density, physical parameters, and land use as the basis for determining the direction of rehabilitation planning. In the estuarine deltaic mangrove typology, we aim at protecting with natural regeneration. In infringe areas, we recommend constructing natural coastal structures before planting. On the backward for intensive planting. Furthermore, mangroves with low density, medium density, and high density are recommended for planting, species enrichment, and protecting respectively, and on the pond with implementing the mixed mangrove-aquaculture system to bridge between rehabilitation effort and economic needs of coastal communities.

Abstract

Peat swamp area is an essential ecosystem due to high vulnerability of functions and services. As the change of forest cover in peat swamp area has increased considerably, many studies on peat swamp have focused on forest conversion or forest degradation. Meanwhile, in the context of changes in the forestlands are the sum of several processes such as deforestation, reforestation/afforestation, regeneration of previously deforested areas, and the changing spatial location of the forest boundary. Remote sensing technology seems to be a powerful tool to provide information required following that concerns. A comparison imagery taken at the different dates over the same locations for assessing those changes tends to be limited by the vegetation phenology and land-management practices. Consequently, the simultaneous analysis seems to be a way to deal with the issues above, as a means for better understanding of the dynamics changes in peat swamp area. In this study, we examined the feasibility of using MODIS images during the last 14 years for detecting and monitoring the changes in peat swamp area. We identified several significant patterns that have been assigned as the specific peat swamp ecosystem. The results indicate that a different type of ecosystem and its response to the environmental changes can be portrayed well by the significant patterns. In understanding the complex situations of each pattern, several vegetation dynamics patterns were characterized by physical land characteristics, such as peat depth, land use, concessions and others. Characterizing the pathways of dynamics change in peat swamp area will allow further identification for the range of proximate and underlying factors of the forest cover change that can help to develop useful policy interventions in peatland management.

Abstract

Geothermal energy activities are allegedly disturbing Kamojang Nature Reserve by clearing the forest. Actually, the national park according to the Law No. 41 of 1999, must not jeopardize the preservation of germplasm in it. Meanwhile, the utilization of geothermal power plant in the area is also required to meet the electricity demand in Indonesia. Land clearing as one of the activity of exploration and exploitation of geothermal coupled with the increasing of human’s activity inside the forest caused widespread deforestation. Since there is a geothermal energy project inside the Kamojang Nature Reserve, then the aim of this study is to analysis the land cover change at Kamojang Nature Reserve from year 2000 until 2011. The research showed that the type of land cover was dominated by forest for about 4231.3 ha with forest cover percentage around 51.17%. Aside of that, the land cover change caused by exploration and exploitation of Pertamina Geothermal Energy was 60.2 ha (8.90 %), while the changes caused by human activities was 614.46 ha (91.10 %). Based on these results, replanting had been done to overcome the worse effect from each activities. The extent of reforestation and enrichment conducted by PGE was 680.58 ha by involving the society who live in surrounding area.
