Abstract

Kota-kota mengalami perkembangan yang sukup pesat. Perkembangan ini akan terus berlanjut di masa datang. Perwujudan perkembangan kota tercermin dari tingginya tingkat urbanisasi, peningkatan perkembangan ekonomi yang ditandai dengan konsentrasi berbagai macam kegiatan ekonomi, terutama industri, jasa-jasa modern, dan perdagangan skala besar. Namun, dalam proses perkembangan kota itu senantiasa dihadapkan dengan berbagai macam persoalan. Saha satunya adalah terbatasnya kemampuan kota untuk menyediakan peluang kerja bagi penghuni yang terus bertambah dengan pesat. Upaya peningkatan ekonomi kota dengan modernisasi infrastruktur kota (perbaikan jalan, sarana perkantoran, listrik, telpon, dan sebagainya) dalam rangka menarik investor terus dilakukan, tetapi upaya tersebut kurang menunjukkan hasil yang memuaskan, khususnya dalam penciptaan peluang kerja di sektor formal (modern). Sehingga angka pengangguran di kota cenderung naik. Bersamaan dengan itu, muncullah gejala sektor informal dan kemiskinan di kota.

Abstract

Generally agricultural data could be collected by several techniques, i.e. rural statistic, sensus, administrative by product, multiple frame sampling  surcey, and frame sampling survey regional inventory. However this research aim was stressed on applying of regional inventory for estimating of rice planting area. This research was carried out in Yogyakarta Special Region. Survey method was employed by data collecting from field observation of land cover on seleted area sample. Proportion of the land over was extrapolated for grasping every kind of land covers on population area. Several steps of research are land stratification, composting of frame sampling, segment sample extraction, field works, and data analysis. Digital Map of Rie Field Standard sacle 1:100.000 used for land stratifying, result three polygons are wetland arable, dry land arable, and highland arable. Based on the frame sampling and its extraction used Systemic Aligned Random Sampling, were selected 53 segment sample distributed in 32 sub districts. Data analysis was performed through desriptive technnique in which mathematically analysis was mmostly used. Result of the research indicates that the regional inventory approach is suitable enough for estimation of rice planting area. However several modifications need to be adapted to the region characteristic. The result of the estimatio shows that the rice planting area on the first period since land preparation up to harvest season (May 2002) is 23,694 ha. Generative phase of rice planting is dominant on the riice field. This phase indicates that the area prediction of rice harvest on July 2002 is about 10,028 ha. The acumulative area of rice harvest on period May – September 2002 is estimated about 22,269 ha. The result of this research finds out that the rice planting area on the second period (July 2002) is predicted about 12,780 ha. On this period, the area is dominated by the phase of rice harvest about 7,015 ha. Based on the rice planting area at phase generative on this period can be predicted that rice harvest area up to September 2002 is about 2,743.7 ha. The acumulative area of rie havest on period July up to the end of November 2002 is estimated about 5,764.87 ha. In generally, regional inventory approach is suitable for estimating for rice planting area.

Abstract

Forest people land use pratices with economic and ecological orientation have been developed in the vicinity of forest areas. Nevertheless, policy makers view this development as detrimental to the forest it self. Forestry programs directed to accommodate public participation are uniformly designed and implemented, ignoring the physical and social variantion of rural areas. Thus there is a need for research on spatial variation of the social forestry program especially related to its success and impact on welfare. The research is carried out in Yogyakarta speial province employed a survei method and spatial approach. Stratified cluster sampling is used on the basis of variations in physiographic characteristics. Secondary data are also collected in forms of literatures and previous research in the field. Primary data are obtained through a structured interview using a set of questionnaires. Data are analyzed using simple tabulation method as well as statistical techniques.The research shows that in general people forest land use has been sucessfully implemented in the province. It is important to note that a more successfull implementation of people forest land use is found in the private rather than government initiated forest. In the less accessible areas people forest land use activities are much more successfull than in the accessible ones. Social forestry land use in the volcanic slope physiography is much better than that in either undulating or karst areas. Among important factors affecting the success of people forest land use are land ownership, education level, technology, land accessibility and percentage of plant growth. It is also confirmed that accessibility is the most important factor affecting the success of an people forest land use. The research also reveals that people forest land use has been very important in improving the farmers welfare. A composite indicator shows that the welfare of farmers is much improved after the adoption of people forest land use, with the highest achievement is obtained by farmers in the volcanic slopes.

Abstract

Application of regression statistic to analyse geography data is getting familiar, as the reason that geography object is really wide, kwantitative approach of geography and availibilty computer software of regression analysis which is getting complete and refresentative. The way of making decision and prediction constitutes the superiority of regression analysis and constitutes the issue which is often met by geographer in the study of geography object. It not only phenomena of human geography, but phisycal geography phenomena is also able to be approtached by regression analysis. For user the attentions that ought to be noticed are 1) regression statistic ought to be appraised as a fool and not as a brain, so that researcher is the main important operator; 2) mastery of geography subject matter constitutes an essential basis; 3) statistic is able to work if there is a detum which is able to fulfill the term of requirements and preceded by a logic causal relation; 4) close attention of reasearcher is highly required; 5) when must, researcher use the  statistic and the relationship between data type and statistical technique.

Abstract

A study of spatial disttribution of urban failities and its impact on settlement pattern had been conducted. Southern part of Surakarta Municipality is chosen as study area. The aim was to study the correlation between spatial distribution of urban public facilities and settlement pattern. To obtain the settlement pattern and urban facilities distribution, manual photo interpretation and field survey method were used. The data were analyzed using geographi information system and statistical analysis tools. Map overlay module in the P Ar/ Info was used in order to join each variables of this research. To know the correlation between spatial distribution of urban facilities and settlement pattern, the multiple regression technique was used. The result shows that there was a positive signifiant relationship between urban public facilities distribution and settlement pattern. It means that the more distributed of urban publi facilities the better of settlement pattern (dense – uniform – large size building). Finally, condition of settlement pattern depends on how the goverment was able to manage the distribution of urban failities.

Abstract

The technical Remote Sensing and Geographic Information System (GIS) had been used to detet vegetation changing of natural forest due to management differences. The target of the study were to determine classification method of satellite imagery in operational scale so that the method can be transfered and applicable for the user. The studied was done at forest concession of PT SLJ-IV (Sumalindo Lestari Jaya-IV), Yanjung Redeb, east Kalimantan Province. Landsat TM with 7 bands and high resolution of 1994 and 1996 were used to differentiate the condition before and after cutting in 1995. The analysis of the Landsats were only in the area where the TPTI (Indonesian Selective Logging System) and TPTI (Indonesian Strip Logging System) system applied. Based on the analysis and field check, it was found that the impact of logging caused decreasing dense forest about 21,3% and inreasing secondary forest around 6,3%. The highest dynamic of each band was band first and the lowest was band second. The differences in the mean of 2 band will give a more clear appearance of the  imagery.

Abstract

The purpose of this study is to analyze land use changes in the Kelara watershed and to assess the suitability of current land use changes with the spatial planning regulation of Jeneponto within Kelara basin. This study integrates various survey techniques, remote sensing, and geographic information system technology analysis. Geospatial information used in this study consists of Landsat ETM 7+ satellite imagery (2009) and Landsat 8 (2014) as well as a number of spatial data based on vector data which is compiled by the Jeneponto Government. Remote sensing data using two time series (2009 and 2014) are analyzed by means of supervised classification and visual classification.  The analysis indicated that land use type for the paddy fields and forests (including mangroves) converted become a current land use which is inconsistent with the spatial planning regulation of Jeneponto.The use of land for settlement tends to increase through conversion of wetlands (rice fields). These conditions provide an insight that this condition will occur in the future, so that providing the direction of land use change can be better prepared and anticipated earlier.

Abstract

This research was carried out in the Coastal Area of North Java, District Brebes, Central Java. It aims at finding the mechanism of factor that influence the dinamics of coastal geomorphological process and the distribution of the dynamics of the geomorphological process. The primary data consist of coastal forms, coastal building/ human activity, sea current, and distribution of the coastal sediment were collected by field observation and measurement. The secondary data consists of the climate, wave, bathimetry, tide, and regional sea current were collected from the related institutions. The technique of data analysis includes Beaufort Scale is employed to find out the characteristics of wind and wave. The laboratory analysis is used to find out the distribution of the coastal sediment. The discriptive analysis is used to desribe the sea current, tide, bathimetry, and human activity.The outcome of this research indicates that Mousoon wind making waves and longshore current can transport sediments which come from Cisanggarung and Pemali river. The small range tide (95 cm), the fine coastal sediment (clay), the shallow bathimetry (0 – 5 m), and human activity (building coastal pand) to provoke the dynamical changing of coasline. The dynamics of the geomorphologycal process from 1944 to 1964 indicates that the coastal area progressed dynamicly; from 1964 – 1997 indicates that the some coastlines (location 1, 4, 5, and 6) progressed, some coastline (location 2, 3, 7, and 8) regressed, and some coastlines (between location 3 to 4 and location 6 to 7) were relativelly stable.
