Abstract

ABSTRAK: Waduk Krisak merupakan outlet dari sungai DAS Krisak yang terletak di Kecamatan Selogiri, Kabupaten Wonogiri. Kondisi saat ini waduk tersebut telah beroperasi selama 72 tahun dengan umur usia guna yaitu 98 tahun. Namun kenyataanya perubahan tata guna lahan serta tingginya laju sedimentasi mengakibatkan berkurangnya sisa usia guna waduk. Studi ini bertujuan untuk mengetahui laju sedimentasi yang masuk dan untuk mengetahui sisa usia guna waduk Krisak. Dalam studi ini dilakukan perhitungan erosi menggunakan metode USLE (Universal Soil Loss Equation) sehingga dapat diketahui besarnya SDR (Sediment Delivery Ratio), dan perhitungan Trap Eficiency dengan metode Brune sehingga dapat diketahui laju sedimen yang terjadi dan perkiraan sisa usai guna Waduk Krisak. Kemudian membandingkan hasil dengan pengukuran echosounding yang dilakukan oleh pihak BBWS Bengawan Solo. Dari hasil perhitungan, didapatkan sisa usia guna waduk berdasarkan erosi dengan R metode Utomo dan Mahmud sebesar 87,44 tahun, erosi dengan R metode Lenvain sebesar 117,92 tahun, sedangkan berdasarkan trap efficiecy sebesar 86 tahun dan berdasarkan echosounding sebesar 86,38 tahun.   ABSTRACT: Krisak dam is an outlet from Krisak Watershed is located in Selogiri District, Wonogiri Regency.

Abstract

Wlingi Watershed at river flow Brantas River and located in the Jegu Village and is about 16 km east of Blitar City. The inhabitants of Wlingi Basin are predominantly farmers and thus have great potential to increase the acceleration of land conversion in the watershed. Estimation of erosion and integrated conservation techniques is needed in managing the Wlingi Basin, so its utilization can be run optimally and maintained to be utilized by future generations. This study aims to find out distribution of level of erosion grade in 2011, 2016 and after simulation of land conservation changes in Wlingi Basin. The method used is USLE (Universal Soil Loss Equation) with ArcGIS software. From the result of analysis it was found that level of erosion grade of 2016 in the Wlingi Basin area covered by very slight (<1,75 tons/ha/year) to very severe (>92,5 tons/ha/year) with percentage of erosion grade 35,23%, 31,70%, 18,11%, 6,71% dan 8,24% respectively. Land conservation directives are carried out to reduce the rate of erosion. The post-conservation in the Wlingi Basin area includes very  slight  to  very  severe  with  the  percentage of  47,68%,  31,43%,  9,66%,  6,10%  dan  5,12%. Decreased erosion rates are good occured following the simulation of land conservation, so land conservation is a mandatory for sustainable land using.

Abstract

Di kabupaten Tuban merupakan Kabupaten yang berada tepat pada garis  pantai utara. Di daerah pesisir pantai memiliki kerentanan terhadap muka air laut,salah satunya adalah kawasan pesisir yang terletak  di pantai utara jawa yang bertepatan langsung dengan daerah studi yaitu daerah yang berada di Kecamatan  Palang, Tuban Kota dan Kecamatan Jenu Kabupaten Tuban. Pemilihan kawasan pesisir Tuban  didasarkan pada letaknya yang berbatasan langsung dengan laur jawa serta berada di jalur transportasi darat pantura  selain itu  didasarkan pada kecenderungan pertumbuhan pesisir tuban yang memiliki potensi sebagai kawasan utama penggerak ekonomi wilayah. Dari data diatas peneliti memutuskan untuk meneliti tentang intrusi air laut di pantai utara Kabupaten Tuban yang diduga terkena intrusi air laut. Hal ini jelas dapat mengganggu kualitas air bersih di daerah pemukiman penduduk yang ada di sekitar kawasan utara Kabupaten Tuban. Untuk mengetahui sejauh mana intrusi tersebut terjadi maka perlu dilakukan identifikasi intrusi air laut menggunakan metode geolistik konfigurasi wenner. Berdarsarkan observasi dan informasi geologi diatas, penulis merasa perlu untuk dilakukan penelitian tentang  Aplikasi Metode Geolistik untuk Identifikasi Intrusi Air Laut di Tuban Utara. Tuban District is a district that is precisely located on the northern coastline. Coastal area has vulnerability towards seawater surface; one of them is a coastal located on the North Coast of Java that coincided directly with the study area that is located in Palang Sub-district, Tuban City and Jenu Sub-district, Tuban District. The selection of Tuban’s coastal area is based on its location that directly coexist with Java Sea and is located on northern beach transportation’s route. Furthermore, it is also based on the growth tendency of Tuban coastal area which has potential to boost its regional economic productivity. From the data above, the researcher decides to investigate the intrusion of seawater on the north beach of Tuban District that is presumed to be exposed to seawater intrusion. It is extremely obvious that seawater intrusion can damage the quality of fresh water supply in residential areas of the northern part of Tuban District. Thus, the researcher uses Wenner Configuration Geo-electric Method to identify how far the intrusion happened. Based on the result of the observation and information above, the researcher needs to do research about the Geo-electric Application Method to Identify Seawater Intrusion in North Tuban.
