POLA PERUBAHAN PENGGUNAAN LAHAN DAN EVALUASI PEMANFAATAN RUANG DI KABUPATEN BANJARNEGARA, PROVINSI JAWA TENGAH

The relatively constant availability of land in a region causes competition in its utilization with various landuse-change consequences. One of which is being the important triggering factors of landslide hazard, particularly in vulnerable regions, such as those working in Banjarnegara Regency, Central Java. This research was aimed at: (1) to identify landuse changepattern in 2001-2015 periods, and (2) to evaluate spatial utilization or existing land use consistencytowards spatial pattern allocated in RTRW of Banjarnegara Regency and its relation to landslide events and their locations. Methods used consisted of Landsat images spatial-analysis andspatial utilization consistency-analysis. Landuse in 2001 was dominated by plantation, dryland, paddyfield, forest,built land, and shrub bush of respectively 40,019, 28,524, 18,319, 10,164, 8,895, and 7,203 ha. In 2008, plantation, built land, shrub bush, and dryland were increasing of 1,781, 978, 618, and 155 ha, while forest and paddyfield were significantly decreasing of 2,498 and1,025 ha,respectively. In 2015,the areas of built land, dryland,plantation, and shrub bushwere ever-increasing of 1,048,474, 464, and 239 ha, while of forest and paddyfield were ever-decreasing of 1,343 and 873 ha, respectively. In 2001-2015, out of 9 landslide events occurred in the less vegetative covered areas, 3 and 2 events were respectively located in the forest-to-dryland, and dryland-to-built land converted areas. Around 37,033 ha land use in 2015 or 32.1% of the total research area exhibited inconsistency towards spatial pattern allocated in the 2011-2031RTRW. [RTRW stands for Regional Spatial Arrangement Plan].

PERENCANAAN PENGEMBANGAN KAWASAN JAGUNG SEBAGAI BAHAN BAKU INDUSTRI PAKAN DI KABUPATEN CIAMIS

Poultry development sector in Ciamis has effected an increasing in maize production as a raw material for feed. In period 2008-2012, the production of maize in Ciamis Region is 45.883 tons, meanwhile, the demand is 17.000 tons, consequently the Ciamis District supposed to be able to fulfill the demand; however, but currently the feed industry in Ciamis are still importing the maize. Cluster development might be one of solution for this problem. The aims of this research are: (1) Analyzing land availability for maize development in Ciamis District, (2) Analyzing maize cluster type can be developed in Ciamis District, 3) Analyzing strategies in development of maize cluster. The results showed that land availability for maize development in Ciamis Regency is 28.176 ha. There are three maize cluster types that can be developed in Ciamis as follows: pertumbuhan cluster (15.671 ha), pengembangan cluster (12.217 ha) and pemantapan cluster (288 ha). Considering the region development strategy, the priority in pertumbuhan cluster type is an optimization of natural resources (land factor), in development type is human resources development with focused to the education and training of field staff, and in the pemantapan type is an institution empowerment with focused on the partnerships.

ANALISIS KESESUAIAN LAHAN UNTUK KOMODITAS SAYURAN UNGGULAN DI KABUPATEN BATANG

Batang Regency has potential land resource for the development of vegetable commodity because it has a diverse agroecological conditions, ranging from coastal areas, plains and mountains. However, these conditions have not been matched with adequate vegetable productivity because it is still below the average productivity of Central Java province. The purpose of this study were to know the primary commodities of vegetable in Batang, to know the land availability for development of primary vegetable commodities and to know available of land suitability for development of primary vegetable commodities in Batang. The analytical method used in this study were : LQ and SSA, land availability analysis and land suitability analysis.The results showed that the primary vegetables in Batang are potato, carrot, long bean, large pepper, cucumber, cayenne pepper, eggplant, cabbage and mustard. Available land for development planning based on primary vegetable horticulture area are 28.558 hectares.The results of soil analysis showed that the potential suitability classes for potatoes, cucumbers and carrots have potential level suitability of S2 and S3. Long bean,chili large, cayenne pepper, eggplant, cabbage and mustard have a potential level suitability of S1 (highly suitable) although that area were not too large.Batang Regency has potential land resource for the development of vegetable commodity because it has a diverse agro-ecological conditions, ranging from coastal areas, plains and mountains.

Impacts of Oil Palm Plantations on Climate Change: A Review of Peat Swamp Forests' Conversion in Indonesia

Indonesia possesses a rich biodiversity with abundant natural resources such as tropical rain and peat swamp forests, oil and gas deposits, and fertile soils just to name a few. The state policies on natural resource management were decentralized and the power and local autonomy rights were given to provincial and district governments. This resulted in an enormous expansion of oil palm plantations across the country especially over the last three decades. On the one hand it boosted the countrys economy by bringing foreign money reserves, but on the other hand has led to severe deforestation, shifting cultivation, peat swamp forests conversion and land degradation. Thus, due to the severity of these environmental consequences and associated climate change implications, oil palm development has received significant attention from all stakeholders and is the subject of global debate. This paper aims to discuss the results of various studies regarding emissions of GHGs from oil palm plantations in Indonesia and highlights the fundamental methodologies

Historical Assessment of Forestland Conversion to Oil Palm Plantations in Riau and West Kalimantan, Indonesia

Forest’s conversion associated with the expansion of industrial scale oil palm plantations in the two provinces of Indonesia (Riau and West Kalimantan) was documented using Landsat images that were visually interpreted to create a province-wide map of 11 different land cover types spanning three temporal periods (1990 to 2000, 2000 to 2010 and 2010 to 2013). After analyzing all regions and temporal periods in both provinces only 1.66% (30,452 ha) of oil palm plantations originated on land derived directly from undisturbed forests (0.01% Primary Dryland Forest, 0.00% Primary Mangrove Forest and 1.65% Primary Swamp Forest), while 64.78% (1.18 Mha) were established on land previously covered with disturbed forest (12.14% Secondary Dryland Forest, 0.67% Secondary Mangrove forest and 51.97% Secondary Swamp Forest). Conversion of Dry and Wet Scrublands was documented as 23.82% (0.43 Mha) with 7.43% from Dry Scrubland and 16.39% from Wet Scrubland. Forest conversion to establish oil palm, including both undisturbed and disturbed forest of all types of habitats summed over all temporal periods was proportionally greater Original Research Article Rehman et al.; IJPSS, 6(1): 34-49, 2015; Article no. IJPSS.2015.095 35 in Riau (70.03%: 0.84 Mha), compare to West Kalimantan (59.52%: 0.37 Mha). In both provinces, the largest sources of land for new plantations were Secondary Swamp Forest (43.43%: 0.27 Mha) in West Kalimantan, while (56.40%; 0.68 Mha) in Riau.
