AbstractWater resource is one of natural resources, that is very vital. It needed to be used and to be kept throughly. For those purposes need good and directed plan, in which one of the basic component of it plan have to be supported by available a complete hydrological data and it analysis. One of hydrological data analysis is to estimate runoff of catchement area, which can be used for planning the hydrologi construction. This research aim: 1) to calculate the run off discharge by thornwaite Mather Method, monthly, annualy, and the average on the catchment through a sample of Keduang, Temon, Alang, and Wuryantoro areas; 2) to analyze the difference of the run off discharge (at no. 1) by observation resulted from trend analysis. Based on the calculation, it appears, thornwaite-mather method showed that high discharge (moreover limit 0) in dry month. From the research result, it appears, that calculation discharge graphic had lower differentation than observation discharge graphic. From sample of catchment areas that have been investigated, from the highest to the lowest deviation was Wuryantoro catchment area (78,8%), Temon catchment area (47,38%), Alang catchment area (46,45%), and Keduang catchment area (24,98%) respectively). The condition like above caused by intervation of man. Not only did he influence vegetatively, but he influenced technically as well. From these conservation, technical conservation (flood and construction and reservoir) was the highest influence to run off discharge calculation. The run off discharge that was calculated by thornthwite-Mather Method based on air temperate, rainy, altitude, and water holding capacity only, but groundwater supply didnât be calculated.

Recently, the long term development in Indonesia has changed agricultural sector to the industrial sector. This development can apparently harm our own people. This is due to the waste that is produced from factories. The waste from various factories seems to have different characteristics. This defference encourages us to be able to find out different of methods of managing waste so that cost can be reduced, especially in water treatment. In order that industrial development and environmental preservation can run together in balance, many institutions involved should be consider, especially in the industrial chain, the environment, and human resource, these three elements can be examined in terms of their tolerance to waste.

The researh is carried out at the basi pillar in Surakarta that is estimated has a clear different at ground water quality. The goals of the research area 1) to know actually the distribution of arial zoning at pollution level of the groundwater; 2) to determine the priority scale of clean water supply. Data analysis used in the researh are tendentious analysis and geographical information system. The result shows that groundwater quality at the research place decreases. It can be proved by tendentious analysis that most of the groundwater quality conentration parameter â after being examined â the lower plae, the higher conentration. There are 21 quality parameters used for that research, 15 out of those have an inclining tendency, while the others are flat and decline. The result of 2 overlapping maps, atual zoning and potential zoning, shows that there is mismatching of risky polluted area. It is caused by human fators, some of them are population density, well construction, bad sanitation, individual septi tank, and industrial disposal from irrigation. Based on the result of the research, clean water district corporation is expected to be able to determine priority scale of clean water supply to Surakarta and its surrounding.

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.

The information of rain water quality in Indonesia is rarely recorded, where as it is important for the region in which the source of fresh water is unavailable. Rain water composition is mostly ascertained by water vapour and ions which are available in the atmosphere during vapouration. In fact the rain water composition of coast region is sea water like and rain water chemical composition of urban are then become HNO3 and HSO4, while rain water of active vulcanic region eventuality has a high sulphur-wombed so that its quality sulphuric-acid. For the region in which the source of fresh water is unavailable the rain water is previously sterilized. Sterilization is consecutively done by adding salts, killing all bacteria, spores, and filltering.

The consumption of drinking water for a community is different from one area to the other. This is normally influenced by the population development, socio-economic, cultural, and physical conditions mainly related to the supply of drinking water and how to exploit it. Banyudono district is an area located in the regency of Boyolali. The development of this area depends on Boyolali City and Kartasura district. Such a location enables the area to have a process of the physical and socio-economi developments. In addition, it has an influence upon social behaviour to consume water. This research is aimed at knowing the average consumption of household need and analyzing the factors influencing the utilization of water as drinking water. The result of this research indicated that 1) the average consumption of a human being for drinking water was 79,37 litter a day. It means that the onsumption of a human being for drinking ater generally ranged from 60 to 80 litter a day; 2) most of the ater was consumed to meet basic needs such as cooking, drinking, bathing, and washing; 3) the difference of the average consumption was influenced by the kind of water source and how to exploit it; 4) a parameter of the most significant socio-economic condition that took effect on the average consumption for drinking water was the parameter of income with correlation of 0.362 and the significant level of 0.01.
