Title : Mapping of Food Agricultural Land Sustainability (LP2B) in Purworejo District. Implementation of Act 41 of 2009 on sustainable agricultural land still needs to be improved. Purworejo has a total area of 103,481.75 hectares consisting of rice, dry land and mixed garden. Increased development of a high enough lead Purworejo prone land conversion primarily agricultural to non-agricultural land. Determination of sustainable agricultural land is expected to control the pace of the transfer function. This study aims to determine the parameters for mapping LP2B and LCP2B, determine the basis for assessing inter-parameter calculation and LCP2B LP2B, determine the characteristics of the grouping criteria as LP2B agricultural land and agricultural land mapping LCP2B and sustainable food (LP2B) Purworejo. The data used in this study include spatial data and spatial data tabulated data consists of the Present landuse map the results of high-resolution satellite image interpretation purworejo district scale 1:25,000, topographic maps, maps of land suitability, administration district map boundaries, and maps of raw paddy fields. Tabulation of data consists of the need and availability of food, food balance, wetland conversion, the rate of population growth, and land area requirements. The survey results revealed that the total population, wetland production, planted area, harvested area, conversion rate and balance of food can be used as a parameter to specify the grouping criteria LP2B while land based on the irrigation system and the productivity of more than 5.5 tonnes / ha with IP is more than 1.75. Based on the analysis Purworedjo county has a total area of 38,562 ha area of agri-food consisting of 27,850.18 ha of wetlands and 10,712 ha of dry land. Of the area that became wet LP2B area of 25,826 ha and 5,243 ha of dry LP2B. Sustainable food agriculture land reserve wet (wet LCP2B) 2,024 ha and sustainable agri-food reserves dry (dry LCP2B) 5,469 ha.

The purpose of the study to know characterization of humic and fulvic acids after three months decomposition by fresh organic waste and canning pineapples treatment at Ultisol Lampung. The research was designed with a completely randomized factorial design with three factors in the plot pots 165 cm x 165 cm x 55 cm. The first is fresh organic waste (200 ton.ha-1 chopper pineapple crops, 40 ton.ha-1 cattle manure, 40 ton.ha-1 cassava waste, 40 ton.ha-1 waste pump pineapple, 2 ton.ha-1 mill juice pineapple), and the second is depth on the soil (i.e. 0 - 15 cm, 0 - 30 cm and 0 - 45 cm), the each repeated three replication so total treatments are 24 plot pots. The results showed ameliorant treatment fresh organic waste and canning pineapples can increase the levels of C-organic from <1% to >1.5%. On the control (K0) in two months decomposition did not significantly different at 5%, but the decomposition of humic acid for three months showed significant differences in the treatment of K0, K1 and K2. Utilization of combinations of fresh organic waste and canning pineapples treatment at the depths (0 - 15, 0 - 30 and 0 – 45 cm) can increase the humic acid content about >1.5% in three months decomposition waste. The combination treatment of fresh organic waste and canning pineapples on Ultisol for three months decomposition, able to provide sufficient nutrients especially the availability of C-organic, humic acid and fulvic acid for growth pineapples.

The problems of the study are: (a) how the peri urban agricultural land use changes, (b) what factors influence land use cahange, (c) how the impacts of the land use changes on regional food lost, food availability, and the prospects of the farming sustainability in the peri urban area ofYogyakarta city. The objectives of the study are (a) to estimate the area and the rates of the peri urban agricultural land use change, (b) to estimate the factors influencing the land use change, and (c) to estimate the impacts of the peri urban agricultural land use change to the regional food lost, regional food availability, and the prospects of the farming sustainaibility in the peri urban area of Yogyakarta city..The data collection methods used in this study are: (a) Landsat TM satellite Images analysis, (b) digitally map overlaying on computer screen using Geographic Information System (GIS), (c) documentation of secondary data, (d) interview with quetionare as the guide, and (d) field observation. Data will be analyzed by using the mathematics, statistics, and econometrics equations specially multiple linear regression. Data will be presented as the table, diagram, curve and map.The results and conclusions of this research are (a) the changed of peri urban agricultural land use as long as 11 years from 1996-2007 are 922,17 ha in Sleman; 1.888,60 in Bantul; and 1.082,79 ha involving 47 sample of villages; the rates of land use changing is in negatif correlation with the the distance from the city, (b) the used econometric model in this research indicate a satisfaction goodness of fit with R2 of 0,895. Based on the analysis of variance, F-test, and t-test can be conclude that some factors i.e. Exhange Value of Agriculture Production (FPV), Technical Irrigated Agriculture Lands (IRG), the Precentage of Built Area to the Agriculture Lands (BCPr), People Density (Dens), Society Education (Edu), and the Agriculture Land Price (FLP) significantly influence to the rates of agriculture land changes, but the other factors i.e. the Precentage of agricultural lands to the village area (FLPr), Agriculture Lands Tax (FLT), Dummy of Bantul (DB), and Dummy of Kulon Progo (DKP) do not significantly at the α of 5-10%, and (c) the rates of agricultural lands changes have negative impacts to the regional food lost, regional food availability, and the prospects of the farming sustainability of peri urban agricultural lands. The number of regional food lost equivalent with 703,443 people, and the decreasing of regional food availability is equivalent with 572.259 people.Keywords: landsat image, land use change, overlay, peri urban
