Permasalah sumber daya air selama ini tidak hanya semakin meningkatnya jumlah air yang dikonsumsikan untuk air minum, pertanian dan industri, namun sudah masuk mengenai masalah pencemaran dan kerusakan sumber air. Tulisan ini membahas tentang sumber daya air permukaan khususnya sungai. Sungai di Indonesia selama ini banyak dimanfaatkan oleh masyarakat di sekitarnya sebagai sumber air domestik, industri, pertanian, maupun tempat pemhuangan limbah, baik limbah padat maupun cair. Tindakan masyarakat dalam memanfaatkan sumber daya air yang tidak memperhatikan keseimbangan lingkungan tersehut akan merusak hubungan antara komponen ekosistem yang akhirnya akan merusak lingkungan itu sendiri. Kerusakan lingkungan pada suatu sistem Daerah Aliran Sungai (DAS) akan berakibat pada penurunan sumber daya air sungai. Untuk itu perlu sekali diupayakan perbaikan terhadap kerusakan sumber daya air yang terpadu pada sistem DAS, mulai dari hulu sampai hilir sungai.

The purpose of this research is to analyze the potency of land water in the post tectonic earchquake at Merapi slope in Klaten regency, Central Java. This research applies a survey method. The result of analysis is made based on the trilinier diagram, Stiff pattern, and the quality standard of drinking water. The collected data are in the form of land form, shallow land water data, suppressed land water, and well or spring. The results of the sesearch show that 1) the land form in Klaten is divided into four sets of landform, they are peak and slope of volcano, feet of volcano, fluvial palin under volcano, and a set of structural morphology. 2) The potency of land water can be tested based on the amount of land water and the quality of land water. The amount of land water in Klaten regency 260,502,274 m3/year or 727,618,722 liter/day. The amount of land water above is taken from free land water 73,301,436 m3/year, suppressed land water 34,138,520 m3/year, and land water taken from well or spring 153,062,784 m3/year. The quality of shallow land water in Klaten regency is proper to consume. 3) The distribution of upland water potency happens in the feet volcano land form, the potency of medium land water happens in the superficial of fluvial under volcano land form, and the potency of lowland water happens in the slope volcano land form and in the structural range of hills at Bayat subdistrict, 4) The tectonic earthquake gives serious effect toward morphological changes, land split, land subsident and the potency of land water in the fluvial plain of land form under volcano and structural range of hills in the area of Bayat subdistrict, and 5) In 2008, the needs of drinking water in Klaten regency is predicted around 1,164,000 people x 150 liter/day = 174,600,000 liter/day.

This study aimed: (a) to determine the general water balance at the Upstream and Midstream of Bengawan Solo Watershed by using Thornthwaite-Mather model, and (b) to determine the fulfillment of domestic water demand in the Upstream and Midstream of Bengawan Solo Watershed. Prevailing climate change has affected the condition of water source in Upstream and Midstream of Bengawan Solo Watershed. One of the impacts was extreme fluctuation of meteorological water availability that might cause flood and drought. Survey was selected as the research method while descriptive quantitative method was used for data analysis. The findings indicated the difference between precipitation and corrected evapotranspiration (P-EP) at the Upstream and Midstream of Bengawan Solo Watershed was between (-11.19 mm) to (78.56 mm). The highest value was obtained by Bambang Sub-watershed and the lowest was Wiroko Temon Sub-watershed. Positive value indicated the water surplus while negative value indicated water deficit. Domestic water demand for local communities was in the range of 50,782,500 liters to 131,690,700 liters, and the level of water availability varied, namely fulfilled and unfulfilled.Â

The study was carried out in Ungaran. The goals of this study are to know and to evaluate the potential spring to add drinking water of Ungaran population. This study uses observation and secondary data analysis. The collected data are meteorology data, the water production of Municipal waterworks, the quality and the quantity of springs, the number of population and the customers. The result of the study shows that there are eight springs with the total debit 157 liter/ second or 6739 m3/ day. The Municipal Waterworks uses 65 liter/ second or 5616 m3/ day with the leaking rate 7% or 5222,88 m3/ day and the rest is used for irrigation. The quality of spring is qualified for drinking water requirement. The need of drinking water for per capita of the population is 136.7 liter/ capita/ day. In 2003 the prediction of the number of consumers is about 20.745 persons, so the total need of drinking water is predicted about 2835.8 m3/ day. The total need of drinking water added with the leak water is 3032.36 m3/ day. The Municipal Waterworks fulfils the need of drinking water for the population especially for the consumers of Municipal Waterworks. However, if the number of customers is accounted based on the number of the population in the pipe sope (+ 48246 persons), the Municipal Waterworks will not fulfil the need of drinking water for population, therefore it needs to add volume production of drinking water.

This research aims to develop and evaluate a geospatial application for groundwater resource management at Karanganyar Regency. The system development methodology from Whitten and Bentley (2007) was used in this research. To initiate the project, we discussed with the stakeholders from Karanganyar Regency which came from various related agencies followed by a focus group discussion (FGD) to analyse the system. Computational design and experiment were conducted to design the system prototype. Finally, we implement the system in the Regency. The result shows that the system is complex not only due to the managerial procedures but also the number of involved users (stakeholder) in the system. To address the emerged requirements from the FGD, we propose and develop a web-based GIS application with current open source technology and Google Map API which can be used for collaboration among stakeholders as well as for supporting the decision support purpose in the groundwater management. Currently, Air-tanah, the prototype of the application is available at http://geografi.ums.ac.id/air-tanah/. Both quantitative and qualitative evaluation of the system resulted good responses from the users.

Umbul Sungsang spring located in the foot of a Merapi is on shift zone between volcanic foot plain and fluvial volcanic fott plain constitutes spring belt. Up to the present, the population use that spring for drinking water and irrigation. The planning of taking water by Municipal Waterworks to supply Solo population causes people around it worried because the usually use that spring. Therefore it is needed to conduct a research to know the potential of that spring. The aim of this research is to account how much the need of drinking water, manucipal waterworks and irrigation and the potential of the spring which is available. The research uses survey method. Primary and secondary data are collected, analyzed quantitatively by using software aid to do simulation the need of irrigation. The result of the research shows that the need of drinking water is 0.068 lt/second/day taken in dry season; manucipal waterworks uses 200 lt/second/day and for irrigation is about 442.2 lt/second/day with the pattern rice – tobacco – rice. Irrigation is also supplied from Bendung Bukur Ireng. The result of the research also shows that in October period I, II, III, and November period II and I lack of water. Therefore municipal waterworks must not use water on Otober and November, while on July and September adjust to the rest of discharge of water, which is available. Its water quality fulfils the requirement for various needs.

Penelitian ini bertujuan untuk mengetabui kondisi irigasi serta pengaruh perbaikan irigasi terhadap perubahan sosial masyarakat desa Bugo, terutama terbadap penguasaan lahan, pola tanam, pendapatan, dan penyerapan tenaga kerja serta hubungan kerja pada bidang pertanian. Pendekatan yang dipergunakan adalah pendekatan kualitatif, dengan pendekatan ini diharapkan akan mendapatkan informasi yang diharapkan, guna menunjang pembahasan penulis berusaha mendapatkan data kuantitatif yang relefan. Dari hasil penelitian ini diketabui bahwa petani pada desa Bugo masih banyak yang merupakan petani tradisional, artinya mereka masih enggan untuk menerima teknologi yang baru, lebih suka pada cara-cara yang biasa dilakukan oleh pendabulunya. Pada perbaikan irigasi menegemen dan saluran sekunder masih kurang sempurna sehingga air kurang biasa merata penyebarannya pada daerah oncoran. Pegaruh yang timbul pada masyarakat yakni; terjadinya perubahan pola tanam dari padi-polowijo-polowijo menjadi padi-padi-polowijo, dari perubahan tersebut secara tidak langsung juga berpengaruh positif terbadap pendapatan rumah tangga petani. Dengan petani-petani tiap bektarnya bertambah, ternyata tidak terjadi polarisasi penguasaan lahan pada petani kaya, dari 142 petani didapatkan 38.7% dari jumlah tersebut petani miskin menguasai 17.2% luas lahan. Hubungan kerja pada petani juga belum nampak adanya komersialisme, hanya saja ada kecenderungan sebagian dari mereka memanenkan hasil panenannya kepada “pengedos”, dan sebagian besar masih dipanenkan pada tetangga dengan sistem “derep”. Tanaman padi ternyata banyak menyerap tenaga kerja dari pada tanaman polowijo pada daerah tersebut. Usaha sektor non pertanian pada daerah tersebut yang berkembang adalah usaha industri rumah tangga pangan, pada usaha ini ternyata juga cukup menyerap tenaga kerja dan memberikan penghasilan pada penduduk yang cukup lumayan.
