AbstrakKeberadaan mata air karst sangat penting karena dapat berfungsi sebagai sumber air minum. Analisis hidrograf mataair karst merupakan langkah mendasar untuk menilai dan mengetahui kondisi daerah tangkapan air di daerah karst. Kurva resesi dipahami sebagai bagian paling stabil di hidrograf banjir tunggal yang mewakili karakteristik akuifer. Oleh karena itu, analisis kurva resesi digunakan untuk menentukan karakteristik akuifer, termasuk tingkat karstifikasi. Makalah ini difokuskan pada bagaimana menentukan derajat karstifikasi. derajat karstifikasi yang digunakan dalam makalah ini diperkenalkan oleh Malik (2007) yang juga memperhatikan analisis kurva resesi. Metode ini difokuskan pada karakteristik independen sub-rezim pada periode resesi. Kurva resesi adalah masukan utama untuk membuat persamaan recessional yang dikonversi menjadi nilai derajat karstifikasi. Skala kualitatif mulai dari 1 sampai 10 mewakili tingkat karstifikasi. Kedua metode tersebut berlaku umum di Indonesia. Kata kunci: Airtanah, derajat karstifikasi, hidrograf, manajemen

This research is an early step to determine the location of rain gauge station for artificial neural network modeling. The implementation of this model is very useful for water quality monitoring. The objectives of this study are: 1) to study the distribution of watershed parameter, that are average annual precipitation, land use and land-surface slope, 2) to conduct vulnerability analysis of watershed contamination, 3) to determine the location of rain gauge station. The study was performed by weighing and rating method of watershed parameters. The vulnerability degree of watershedtocontaminationispresentedasvulnerabilityindex.Thisindexisdeterminedbyoverallsumofallmultiplication between score and weigh number of each parameter. All data manipulation and data analysis were performed by using Geographic Information System (ArcView version by 3.2). The vulnerability of watershed contamination map had been generated using overlay operation of parameters. The results show that vulnerability index are varies between 10 up to 40 intervals. Hence, the indexes were categorized into three levels of watershed vulnerability, namely low (10 – 20), moderate (20 – 30) and high (30 – 40). It is found that the study area covered more by high vulnerability of watershed to contamination. The zoning of watershed vulnerability meant to determine the rain gauge location. There are three rain gauge stations on the area that they are in a high vulnerability level, whereas the other vulnerability level area has one rain gauge station. Each level of vulnerability area is able to represent the source of contaminant that it maybe influence the water quality of Gajahwong river.

The solar radiation is the most important fator affeccting evapotranspiration, the mechanism of transporting the vapor from the water surface has also a great effect. The main objectives of this study were to investigate the potential of using Artificial Neural Network (ANN) to predict solar radiation related to temperature. The three-layer backpropagation were developed, trained, and tested to forecast solar radiation for Ciriung sub Cachment. Result revealed that the ANN were able to well learn the events they were trained to recognize. Moreover, they were capable of effecctively generalize their training by predicting solar radiation for sets unseen cases.

Potential evaporation (ETp) can be calculated by ETp models climatological parametrs. Among them, the Penman model is most frequently used for ETp estimation. The penman model requires five climatic parameters : temperature, relative humidity, wind, saturation vapor pressure, and net radiation. It also uses complicated unit conversions and lengthy calculation. There are a simple models such as : Jensen - Haise models, Hargreaves, Radiation, Turc's, and Makkink's model. These models that requires only two climatic parameters, temperature and incident radiation.

In the environmental viewpoint, water and land characteristics are strongly influenced by some aspects such as layout, position, landscape development, natural factors and human activity impact.Spatial aspects of land and water resources are the asset of spatial-based national development. Land resources management need to consider the characteristic of both renewable and nonrenewable land resources.Hydrological characteristics is a result of interaction and interrelation of human socio-economic parameters with some watershed physical factors. Apart from that, besides land use as physical factors, there are some other factors such as morphometry, lithology, geomorphology and geology. They are all naturally come from a watershed that cannot be altered by a human (unmanageable). Some combination of watershed physical factors and the manageable factors such as land use plan, slope, and slope length will give a specific watershed response to the rainfall. Eventually, this affects the large-small of river flows behavior. Baseflow river is an essential substance for the development of water resource management strategies at watershed scale. Therefore, this study aimed to estimate baseflow river recession at various geological formation. It also influences characteristics of baseflow recession in Wuryantorosub-watershed at Wonogiri district. Simultaneous Statistical Analysis (ANOVA) and partial (t-test) analysis show that there is a significant influence on the variation of land use in diverse geological formations toward the baseflow recession, with a determination coefficient value - Adjusted R-square is 58.1%.The simultaneous analysis describes a simultaneously effect of recession baseflow coefficient with value test of the test F table > F count at a level of confidence by 5%, and a partial analysis shows that all land use variations in three geological formations significantly influence baseflow recession. Recession model of these two relations is Y = 1.426 + 0,583X1 + 0,384X2 + 0,269X3. This condition indicates that baseflow recession is influenced by some basic by a number of entire environmental attributes. Thus, there will be a sustainable synergy of baseflow recession management that maintain river pattern by the surrounding inhabitant as an alternative water supply for local communities. Keywords: Baseflow, perennial river, variations in land use, geological formations

Air permukaan menjadi salah satu sumber daya alam yang paling rentan mengalami pencemaran akibat adanya tekanan dari faktor alami dan aktivitas antropogenik yang kompleks. Hal tersebut menimbulkan kekhawatiran kelangkaan air tawar di masa depan. Oleh karena itu, evaluasi kualitas air secara kontinu diperlukan untuk melestarikan sumber daya air tersebut. Penelitian ini bertujuan untuk menganalisis kerentanan air permukaan terhadap pencemaran di Daerah Aliran Sungai (DAS) Cimanuk menggunakan metode overlay dalam Sistem Informasi Geografis (SIG) dengan parameter penggunaan lahan, kemiringan lereng, dan rata-rata curah hujan tahunan. Peta penggunaan lahan didapatkan dari citra Sentinel-2B, kemiringan lereng dari Shuttle Radar Topography Mission (SRTM) dan data curah hujan rata-rata tahunan berasal dari hasil pemantauan BMKG. Hasil analisis menunjukkan bahwa wilayah penelitian memiliki tingkat kerentanan air permukaan terhadap pencemaran rendah (3,72%), sedang (59,24%), dan tinggi (37,04%). Hasil ini memberikan gambaran bahwa sebagian besar wilayah di DAS Cimanuk memiliki tingkat kerentanan sedang dan tinggi dengan faktor yang paling berpengaruh adalah adanya perubahan penggunaan lahan. Informasi ini dapat digunakan sebagai dasar penentuan titik pemantauan kualitas air di DAS Cimanuk yang efisien.

Dusun Gerupuk merupakan dusun yang terletak pada sisi barat Teluk Gerupuk. Mayoritas penduduk di Dusun Gerupuk bekerja sebagai nelayan, baik nelayan tangkap maupun nelayan budidaya. Hasil tangkap ikan nelayan umumnya didistribusikan ke pedagang kecil. Namun, waktu simpan ikan sangat pendek sehingga harus ada inovasi yang dapat memperpanjang waktu simpan ikan tersebut. salah satunya yaitu dengan membuat inovasi produk olahan berupa Abon Ikan. Karena minimnya pengetahuan masyarakat Gerupuk mengenai pengolahan ikan segar menjadi abon, sehingga diadakan pelatihan pembuatan abon ikan di Dusun Gerupuk tujuan dilakukannya kegiatan ini yaitu untuk meningkatkan motivasi masyarakat terutama ibu-ibu dalam mengolah ikan serta dapat memperpanjang waktu simpan dan meningkatkan nilai ekonomi dari ikan. Metode yang digunakan yaitu FGD (Focus Group Discussion). Persiapan uji coba produksi, kegiatan pelatihan, serta monitoring dan evaluasi. Hasil dari kegiatan pelatihan ini yaitu sebuah produk berupa abon ikan serta terbentuknya kelompok usaha yang berjumlah 4 orang. Diharapkan setelah kegiatan ini usaha abon ikan akan terus berjalan dan produk abon ikan bisa menjadi produk oleh oleh Khas Dusun Gerupuk.
