Spatial Correlation Between Land Development Level and Vulnerability Level of Mass Movement in the Watershed of Kayangan, Kulon Progo Regency, Yogayakarta Special Region
No full textThe objective of this research were: 1) to study the degree of soil development, and 2) to study the spatial correlation between the degree of soil development and the degree of mass movement susceptibility in the research area. The sampling method applied in this research was stratified sampling. Soil mapping units were applied as strata. The sample within strata was determined according the degree of mass movement susceptibility. The degree of soil development was determined using quantitative method of color indices and proflie index. The color indices were Buntley – Westin (B – W), Harden (H), and Hurst. The profile index was determined using solum, texture, structure, and soil consistency. The degree of mass movement susceptibility map was taken from PSBA UGM (2001). Spatial correlation between the soil development map and the mass movement susceptibility map was analyzed using “error matrix”. The result of this research indicated that the degree of soil development in the research area could be classified into three classes, i.e. class 1 (weakly develop soil); class 2 (moderately developed soil), class 3 (strongly developed soil). The degree of mass movement susceptibility was classified into three classes, i.e. class 1 (low susceptibility), class 2 (moderate susceptibility), and class 3 (high susceptibility). The result of error matrix calculation between mass movement susceptibility and soil development were 9.56%; 21.96%; 30.21% for BW + Ha, Hurst, and profile indices respectively. There values showed that there were low spatial correlations between the degree of soil development and mass movement susceptibility in the study area

Land Capability in Gobeh Sub Watershed Wonogiry Regency Central Java Province
No full textThe research held on Sub DAS of Gobeh, Wonogiri Regency, have the aims to kno about class and sub-class of land capability in the research area. The other aim is to know about some area developed to the farming land, and to evaluate about land apability currently. The method used in this research is field-survey method, including about observation, measurenment, reording, and laboratory analysis. The sampling method applied in this research is stratified sampling, with land unit stratum. Measurenment and recording in the field inluding about degree of slope, erosion level, soil-deepening, drainage, stone or gravel and flood hazard. The laboratory analysis including about land erodibility, texture, and permeability. The research result identify that, researh fields have three lanf form unit, they are the fluvio volanic foot plain of old Lawu vulcan area flat relief slightly dissected, the fluvio volcanic foot plain of old Lawu mountain area rolling relief medium dissected, and flat foot plain unit can be separated to thirty two land unit. Land capability of the research field identify between level II to level VII. The wide of each land capability are, level II 3 – 8 Ha (2,4%), level III 38,18 Ha (23,7%), level IV 10 Ha (6,33%), level V 107,62 Ha (66,8%), level VII 1,2 Ha (0,75%)
Regional Planning Cartography
Full text linkOn the development of regions, whatever they are cannot be separated from the planning stage before the development stage it self. This paper aims to investigate the role of artography, in relation with the study of regional development, especially in relation with the preparation of map types that are relevant and need for both planning and regional development processes. Planners have agreed that maps are highly neede in the planning process, but much is still debated as to ways of presentation, contents of theme, and suitable scala for planning purposed. There are two groups of maps neede by planners, i.e. status maps that are neede before planning and maps that are neede during the planning process. The selection of how much information needed to be drawn on maps for the aims of regional planning, is a difficult problem to solve and also challenge for us, especially geographers. This paper is only a desription of our contribution of thoughts, not based on any research, but is a compilation from various source/ideas, particularly from cartographer who are experienced in their new field, i.e. “Regional Planning Cartography”
Land Ownership and Income Distribution of People in Ngimbakan and Mranggen Municipality Polokarto Sub-District, Sukoharjo
No full textThe research is conducted in Ngombakan and Mrangeen, two villagein district of polokarto, Sukoharjo regency. The two villages employe two different irrigation systems, one technical and the other non-technical. The study aims at two major objectives, namely: 1) the relation between the width of agricultural land holding and the income distribution of the different irrigation systems employed in the two villages; and 2) yhe influence of land holding having different irrigation systems on the agricultural income, non agricultural income as well as the household income. The sample include 225 respondents selected in proportion. They consist of 75 respondents that come from the village employing the technial irrigation. And 150 respondents from that employing the non-technical irrigation. The samples are taken in random. The analysis is conducted by means of cross-table analysis, frequency distribution, and product moment correlation.The result of the reasearch show that 1) there is small rate of land holding in two village; 2) there is a great deal of inequality of land holding in the two villages in which it is higher in Mranggen than that in Ngombakan (Gini index in Mranggen is 0.668, where as that in Ngombakan is 0.602); 3) there is a considerable inequality of agricultural income in which Mranggen is higher than Ngombakan; 4) there is a slight differene of household income in two villages; 5) there is positive correlation between the widht of land holding and the agricultural income, non agricultural income as well as the household income in Mranggen; 6) there is a positive correlation between the widht of land holding and agricultural income but there is no significant correlation between the widht of land holding and the non agricultural income as well as that of the household. The study was found out that the non-agricultural sector is playing an inreasingly important role in the distribution of household income. The inequality of agricultural income in the villages is considerably high but the inequality of the total income as well as that of the income per capita is relatively low. The contribution of the agricultural sector to the total income is lower than that of the non-agricultural. There is a difference of poverty level in which respondents employing the tehnical irrigation have a lower degree of poverty than those employing the non-technical irrigation
Social Services Planning in Rural Areas: A Theoretical Review
No full textNowadays, the comprehensive and integrated rural development concept has been considered as the right approach in order to combat the root of rural poverty. By its main concern on area planning, i. e. the availability of planning apparatus at local (regional) level, comprehensive local (rural) resource analysis, and multi-disciplinary approach, it is expected that the weakneses of centralized planning which, among others, concentrates on economic growth can be reduced or even eliminated. This paper tries to explain the place of social service planning in the rural development concept above. The approach used is by discussing the place of service planning in the national development policies; collective decision making system, especially related to planning procedure and process; and social service problems in rural areas.
