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.

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 didn’t be calculated.

The objective of the research is to find the most suitable soil conservation practice that may be applied to control landslide hazard. In order to achieve that objective, some research steps must be done, are: (1) to identify the land characteristics of the study area that is based on the understanding of some factors that caused and triggered the landslide hazard, i.e.: slope morphology, rocks/soils characteristics, climatic condition, and landuse; (2) to study the types of landslide that occurs in every landforms and determine the area having ideal landslide form; The proposed landslide in this research is the process of masswasting down-slope as a result of the gravitation action on materials being sliding. The landslide types is including creep, slide, slump, and rocks/soils fall. The methods that being applied in the research include field survey methods and the method for determining landslide hazard by using geographic information techniques. Field survey method was intended to characterize the location of every landslide that have been happened in the study area. The results of field survey were applied as materials for determinating the grade of landslide hazard. Scorring and weighting methods of factors that influence landslide was apllied to determine the grade of landslide hazard. Scor and weight were not same for every parameters used for evaluation. The result of field research shows that landslide happen in every landform unit The study area can be devided into 9 landform unit. The landform units are differentiated into the landslide hazard classes, the study area there were found 5 classes of landslide hazard, namely: (1) vary low hazard equal to 16,65% (1 landform unit); (2) low hazard equal to 7,63% (1 landform unit); (3) medium hazard equal to 37,58% (3 landform unit); (4) high hazard equal to 25,41% (2 landforms unit); and (5) highest hazard equal to 12,73% (2 landform unit). Evaluation of landslide hazard shows hat most of study area have high risk to slide as a result of complex interaction between many factors of landslide.

Air merupakan kebutuban hidup bagi manusia, baik sebagai mahkluk hayati maupun untuk kehidupan sehari-hari (MCK), irigasi maupun industri. Sebagian dari kebutuhan tersebut diambilkan dari air tanah. Dengan semakin meningkatnya jumlah penduduk terutama di perkotaan secara tidak langsung akan berpengaruh terhadap persediaan air tanah yang ada baik kualitas maupun kuantitas. Pengambilan air tanah yang terus meningkat dan melebibi save yield pada daerah pantai akan mengakibatkan intrusi air laut yang mengakibatkan air tanah menjadi asin. Demikian juga semakin banyaknya limbah yang dibuang oleh manusia ke dalam tanah baik limbah rumah tangga maupun industri akan mrngakibatkan pencemaran air tanah. Pada umumnya limbah yang berpengaruh terhadap air tanah di perkotaan adalah limbah rumah tangga (MCK) maupun limbah industri. Pengotoran atau kontaminasi air tanah ini akan berbahaya pada manusia yang telah meminumnya. Oleh karena itu dalam pemanfaatan sumber daya air tersebut hendaknya dapat dimanfaatkan clengan sebaik-baiknya dan dijaga kelestariannya.

slope of Merapi Volcano in Boyolali. The aims of this study are first to know the characteristic of groundwater in every morphological unit, second to know supplying system of fresh water in every each unit.The method used is survey method. The sampling use to know the characteristic groundwater both quality and quantity of the water, and supplying system of fresh by using area sampling. As basic of stratification of its region is morphological unit. Analysis method used is tabulation, laboratory analysis, and graphic analysis to describe its space.The result of the study shows that the quality of groundwater in every morphological unit is good enough, but in general the contents of element Ca, Mg, N03, CI, SO4, HCO3 shows that the lower the region is, the higher the content of the element . But if it is seen from the depth of its groundwater, so that the ﬂuvial volcanic plain is the shallowest, then the ﬂuvial volcanic foot plain and the last the volcanic foot area. Supplying system of fresh water, which derived from the dominant of well water, is especially used in morphological unit in ﬂuvial "volcanic foot plain. The spring water is used by the population in the morphological unit in volcanic foot plain and then in morphological unit of ﬂuvial volcanic foot plain. The population uses much rainwater in the morphological unit of volcanic foot plain.
