Abstract

Persentase penduduk Indonesia yang bertempat tinggal di perkotaan sejak tahun 1920 sampai 1990 telah meningkat dengan cukup pesat. Pada tahun 1920 persentase penduduk kota sebesar 5.8 persen, pada tahun 1990 meningkat menjadi 30.97 persen, dan perkiraan tahun 2000 menjadi 38.3 persen. Implikasi utama dari persoalan diatas semakin meningkatnya permintaan akan ruang untuk menampung fungsi-fungsi baru di perkotaan. Sedang dipihak lain persediaan lahan dikota semakin terbatas. Oleh karena itu pemekaran fungsi-fungsi kota ke daerah pinggiran kota menjadi keniscayaan. Semakin meningkatnya intensitas pemekaran kota ke daerah pinggiran kota menimbulkan beberapa persoalan. Pertama, munculnya fenomena "under bounded city" yang tak jarang memicu munculnya "goal conflict" dalam perencanaan tata ruang antar wilavah yang berdekatan. Kedua, untuk kota-kota di pulau Jawa. Pemekaran kota yang semakin meningkat sedikit banyak akan mengancam prestasi swa sembada beras yang telah diraih, karena sebagian besar lahan potensial untuk pertanian dan suplai beras di Indonesia dihasilkan dari Pulau jawa. Dengan mempertimbangkan sektor pertanian dan pengembangan kota maka disarankan dua strategi yang berbeda untuk pengembangan kota-kota di jawa dan luar jawa. Pengembangan kota-kota di jawa disarankan lebih menekankan strategi yang berorientasi pertanian dengan cara memproteksi lahan pertanian potensial di pinggiran kota. Sedangkan pengembangan kota-kota di luar jawa disarankan menerapkan strategi yang berorientasi kekotaan, dengan memberi prioritas pada pengembangan fungsi kota.

Abstract

The south coastal region of Yogyakarta Province (YSP) in Indonesia has inherited a unique farming system called sawah surjan, which is considered as a cultural heritage that demonstrates a form of local wisdom in managing land resources with poor drainage. The local residents have succeeded in realizing their desire of making the farming system ecologically stable and capable of providing a decent living. As a cultural heritage, however, sawah surjan has been under an increasing threat of conversion resulting from the infrastructure development and spreading of urban developments. This study assessed the prospect of sawah surjan in the rural household economy and its sustainability within the context of changing wider environment. To do so, a household survey was conducted covering 41 farmer households in Depok Village, Panjatan Sub-district, Kulonprogo Regency, Yogyakarta Special Province where the existence of sawah surjan is threatened by the large-scale investments. The research show that sawah surjan contributes to employment generation, diverse sources of income, food security, and income redistribution. It is generally sustainable but the excessive use of pesticides and chemical fertilizers will have adverse effects on its sustainability. The research confirms that the most significant threat is the infrastructural development, especially the prospective construction of a new international airport as increased land prices may lead to uncontrolled conversion of sawah surjan into non-agricultural uses. This is also in coincidence with the stagnant regeneration of farmers in the area that lead to a bleak future of the system.

Abstract

There are some characteristics and distributions of unconfined groundwater variation in the research area. Those are related to a system of water supply and consumptive use for drinking water. Variation of the groundwater characteristic depends on variation of morphology. Therefore, it is needed to delineate hydromorphology units of the regions as a base on groundwater resources management, especially for drinking water. The aims of the research are: (1) to study of the characteristic and distribution of unconfined groundwater variations base on landform units, (2) to study the factors that affect such variations, and (3) to establish the hydromorphology units of the regions for groundwater resources management, especially for drinking water. The method used in this research is landform approach and field survey. The sampling method is stratified sampling, based on landform as the analysis approach. Result of the research shows that there are some variations of groundwater characteristic at each landform. Landforms which have good groundwater characteristic are Hydromorphology Unit of Fluvio Volcanic Plain of Young Merapi (except Bayat region) and Hydromorphology Unit of Volcanic Foot Plain of Young Merapi. At those units, there are good quality of groundwater, bicarbonate water (hydrochemical type I), having low electric conductivity, shallow of water table, low in fluctuation, and middle to fast class in aquifer permeability. Those units are the most potential unconfined groundwater resources management for drinking water. The units which have poor groundwater characteristic are Hidromorphology Unit in Bayat Region, including Undulating Alluvial Plain, Fluvio Volcanic Plain of Young Merapi, and Swamp Alluvial Plain. Generally, the groundwater quality is medium to poor, the hydrochemical type is Va (initiation process of connate water) and type III (evaporate water), shallow up to medium of water table, and low to middle class of aquifer permeability. The taste of groundwater is brackish to saline with high concentration of chloride.

Abstract

This reseach is excecuted in Sidokarto village Godean Subdistrial, Kabupaten Sleman, special province of Yogyakarta, and is derived from the question of how rural community uses formal and in-formal failities of lend institution (credits source) that are available in their villages. Are the debts affecting the income of rural community? The aim of this research is to find out the back ground of rural community life, public choice to decide creditor, and the income of family holder. Methodology applied in the research is a surveying methode. The seletion of the region was executed in purposive sampling tehnique and the respondents were randomly selected. The respondents were the heads of family as debtors who have taken the credit from either government or private. Analysis used in this research was frequency tabulation, cross tabulation and analysis of correlation is done by using product moment technique. The result proved that most of the debtors (more than 50%) are non peasant with low-rank education (passed and dropped out of elementary schools). Among the debtors, the greater part (93.55%), have used the formal merits i.e. KUD and BRI. Debtor's choice of lend institution is in fluenced by aspect of location and the ease of service. It is proved that the more debtors live near to the lend institution, the quality of the debtors will increase. The reason why credit source is used is influenced by the question whether it is easy or not to get the debt, without taking notice of rent, although it is low enough. The result also proved that, for the greater part of debtors have used the debt money to increase the capital for non agricultural ativities.

Abstract

Kendari is the capital of the Indonesian province of Southeast Sulawesi. It is located on mainly the karst hills region with high rainfall and there were numerous human activities on the karst hills. Many landslides have occurred in these areas. Natural and human factors may contribute to the landslide. The purpose of this study was to determine whether the present GIS map of landslide-prone areas was in agreement or compatible when compared to the actual site conditions in Kendari City. This research is mainly a regional survey. Data was collected through direct interview and observation at the sites. Data were analyzed quantitatively with percentages. The results showed that 87.4% of the area in Kendari City as shown in the map of landslide-prone distribution using GIS was included in the low risk or slightly vulnerable category. The category of landslide-prone areas was divided into; Very low risk, Low, Medium, High risk and Very high risk which represents the less vulnerable areas to the very vulnerable areas. The level of compatibility of landslide-prone maps in Kendari City, when compared with actual site conditions, reaches 75%. This shows that the map of the GIS spatial analysis can be used as a guide in mapping the level of landslide vulnerability in Kendari City. Landslide-prone map may be used as a guideline for engineers, designers, planners, and city officials in planning to reduce the risk of potential disaster.

Abstract

The Study, carried out Sukoharjo, deals with the effect of land function change from 1997 to 2002 toward the change of chosen hydrological parameters. The hydrological parameter constituses the coefficient runoff (C), the extra soil water (id), and the amount of constant stream (Wa). The process of land function the change is searched by using landsat image composit RGB (Red Green Blue) 452. Meanwhile, the aims of the study are (1) to determine the types and distribution for the process of land function change, and (2) to analyze the change of coefficient value runoff (C), the extra soil water (Id), and the amount of constant stream (Wa) within the area of research. The result of the study shown that there are many types of land function change, which occurred in almost all the area of research except the one type coming from the river becoming wet/dry rice field/residence/forest of which only occurred in Nguter sub district. The condition because of the straightening Bengawan Solo River in the sub district, cousequenly, the land function change proceses from the river into the land and vice versa. Moreover, of the 7 types of land function change in the area of research, the widest type of land function change covering the whole district is a change from forest/ horticulture/dry or wet rice field into residence. The effect of such a change has also caused a change in the characteristics of chosen hydrological parameter. Such a change can be seen from the value C, Id, and Wa. Furthermore, the change can be clarified as follow: the value C and Wa tend to rise while Id tends to decrease. This mean that the land function change has resulted in great abundant and decrease of water absorbed in the soil. In general, the availability of water source within the area can still be supplied from the seemingly increased constant stream. Such a condition might be caused by the ratio between the built land and the proportional open land of which about 30 % of the whole space.

Abstract

On 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”.

Abstract

Land is natural resources within processing needs to the wise action in order to give good returns for human and being prevented it’s conservation. In the utility of it’s land this land is proper to the agriculture land have sometime emergedthe environment problems, namely the balance of nature is disturbed. It doesn’t mean that land is forbidden to use, but in the it’s utility purposes this land must be considered it’s capability or it’s balance. If form and manner of using this land doesn’t disturb the natural balance, it means to be guaranted. In the countrary, if form and remain to be guaranted. In the contrary, if form and manner of using this land disregard with it’s capability, then the natural balance is disturbed, the land is called asland within dangerous condition or critical land. The coresponding problem that arises in Kecamatan Cepogo under Boyolali district on the surface level land and southern land resembles the critical land that the most erosion appearance can be found assuch sheet erosion, gully erosion, erosion in the other side, vallage forest, settlement land. Mixing estate and the infertile land. This recent exploration purpose is to understand physical factor that affects the critical land as well as to collect and to clarity the critical land. The used method is survey and laboratory analysis by land unit approach ascartography unit. The adopted data of this research is used the effectively width of soil, texture, soil permeability, soil slope, and soil appearance. From this research is understood that the explorated land has three critical land levels, namely; the medium critical land level is 4411,09 are or 17,48%, the wight critical soil level is 7909,74 are or 12,86% of the whole exploration area wide.
