Abstract

Nowadays, 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.

Abstract

The objective of this study is to determine the sensitivity of Citarum river flow to climate change and land conversion. It will provide the flow information that required in the water resources sustainability. Saguling reservoir is one of the strategic reservoirs, which 75% water is coming from the inflow of Upper Citarum measured at Nanjung station. Climate variability was identified as rainfall variability. Sensitivity was calculated as the elasticity value of discharge using three-variate model of statistical approach. The landuse conversion was calculated used GIS at 1994 and 2004. The results showed that elasticity at the Nanjung station and Saguling station decreased from 1.59 and 1.02 to 0.68 and 0.62 respectively. The decreasing occurred in the before the dam was built period (1950-1980) to the after reservoirs operated period (1986-2008). This value indicates that: 1) Citarum river flow is more sensitive to rainfall variability that recorded at Nanjung station than Saguling station, 2) rainfall character is more difficult to predict. The landuse analysis shows that forest area decrease to ± 27% and built up area increased to ± 26%. Those implied a minimum rainfall reduction to± 8% and minimum flow to ± 46%. Those were caused by land conversion and describing that the vegetation have function to maintain the base flow for sustainable water resource infrastructure.

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

Emerging concentration of COx gas as an emision gases that was caused by vehicle will create that air quality degradation in urban area. Air quality mapping was needed as a based map to solved on air quality problem in urban area. The aim of this research are mapping of air quality in Surakarta Municipality and to select the cartographic symbols which optimum to represent of air quality data especially Cox for more readable and analysis. Data collecting based on field survey in some observation point that derived purposively on several roads and dense traffict. Field data plotting on the map are used in some symbols such as pie-graph, bar-graph, and text. The mentioned symbols are usual in cartography to represent of point symbol. The result of this research is distribution map of COx concentration in Surakarta Municipality. The road which has high COx concentration are cross jucntion in downtown (west side of Pasar Klewer), cross junction of Yos Sudarso street, Slamet Riyadi Street, and cross junction of Hay Lay (Wates). The used of pie-graph and bar-graph symbols produce more interesting map visually, but unfortunately the symbols cover up the information in their based map. The used of text symbol is more easy to handle for lay out, so the background object in based map is uncovere, but visually the map is not interesting.

Abstract

Land use change is one of the effects of population growth and increased human activities. Land use change that overlooked the rule of ecosystem sustainability has a propensity to adversely affect the environment, including the decline of water quality. Kali Madiun is a sub-watershed of Bengawan Solo Watershed that allegedly endured the impacts of land use change. This study aimed to investigate the impacts of land use change on the water quality index of Kali Madiun Sub-watershed. Land use change analysis was done by overlay analysis of spatial data including the maps of land use in 2010 and 2015. Samples were the surface water in the upper, middle and lower part of Kali Madiun Sub-Watershed. Water quality analysis was carried out by comparing the results of water quality parameter assessment based on Government Regulation No. 82 of 2001, while water quality index was figured out by an assessment based on the Decree of the Minister of Environment No. 115 of 2003. The results indicated that during the five years observation, there were land use changes in the upper, middle and lower part of Kali Madiun Sub-watershed. Several parameters increased in 2010 to 2015, namely: TDS, BOD, COD, nitrate, detergents, oils and greases. Pollution index shifted from slightly polluted in 2010 into moderately polluted in 2015. We propose a strategy to solve these problems by the involvement of stakeholders and the participation of local community in managing both domestic and industrial wastes. Also, it should be supported by palpable regulations related to land conversion. Furthermore, it is expected that the effort will reduce the potential of pollution and improve the water quality.

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.
