Abstract

This study aims to select vegetation as a landslide controller in the Cengkehan River Valley, Imogiri District, Bantul Regency, Special Region of Yogyakarta. It is adjusted to the characteristics and thickness of the landslide, the height, and slope of the morphology, the typical roots and the suitability of the community interest of the plant species. The slope of the valley is 15°-60° and 75-325 meters above sea level. Landslides are on the north cliff in the direction of landslides, N 234°E, along the morphological orientation directed at N324°E. Landslides are slides that combine with the movement of rocks (wedge failure). Landslide material results from weathering of basalt that the degree of weathering of rock is not continuous between levels III and V. The soil is eluvial sediment which is identified as latosol with thickness up to 2 meters. The recommended vegetation for shallow landslide type is deep-rooted vegetation. They are Dalbergia pinnata and Parkia speciosa, especially for land with slope between 21 to 40%. Recommended vegetation for slopes above 40% is Aleurites moluccana. Latosol conservation for landslide mitigation can be optimized for soil fertility and productivity through the use of straw, leaves and banana peels.

Abstract

Selokan Mataram didominasi berbagai variasi tata guna lahan. Adanya potensi masuknya unsur pencemaran selokan oleh aktivitas penggunaan lahan menjadi pertimbangan pemantauan di Selokan Mataram..Penelitian dilakukan di sekitar Daerah aliran Selokan Mataram yang dibagi menjadi 3 segmen yakni Desa Sidomoyo Kecamatan Godean, Condongcatur Kecamatan Depok, dan Kelurahan Purwomartani Kecamatan Kalasan. Penentuan luas penggunaan lahan Daerah Aliran Selokan Mataram diolah dengan proses digitasi peta menggunakan software ArcGIS. Parameter kualitas air selokan yang diuji meliputi pH, Suhu, BOD, COD dan TSS. Hasil penelitian menunjukkan status mutus air Selokan Mataram pada setiap segmen menggunakan metode Indeks Pencemaran dikategorikan dalam cemaran ringan. Bedasarkan hasil output SPSS, hasil korelasi tata guna lahan dengan kualitas air menunjukkan korelasi negatif diperoleh pH di persawahan, suhu di persawahan, suhu di permukiman, BOD di persawahan, BOD di pemukiman, COD di persawahan, dan TSS di persawahan. Sedangkan hasil korelasi positif diperoleh pH di pemukiman, COD di pemukiman, TSS di pemukiman. Hasil perhitungan daya tampung beban pencemaran metode neraca massa menunjukkan untuk parameter pH 7,15, COD 16,91 mg/L dan TSS 38,26 mg/L masih dalam ambang batas baku mutu yang ditentukan, sedangkan parameter suhu 31,13oC dan BOD 3,475 mg/L tidak memiliki daya tampung. Pencemaran yang mempengaruhi kualitas air Selokan Mataram berasal dari masuknya limpasan domestik dari aktivitas pemukiman, limpasan komersial dan limpasan dari limbah pertanian dan kurangnya vegetasi disekita aliran selokan.

Abstract

Many researchers were conducted using geotechnical sentrifug in studies of the environment. The advantages of using a geotechnical sentrifug are quick to obtain the results, less materials used, economical and can be controlled for factors that are not required in the test. All geotechnical sentrifugs that were conducted are located outside from Indonesia and Malaysia, so that requires for build a geotechnical sentrifug in the country. Engineering methodology was to modify the existing geotechnical sentrifug in other countries. The geotechnical sentrifug that was build Universiti Kebangsaan Malay-sia is 50 cm radius beam type geotechnical sentrifug with dead lock capacity 6 kg and maximum acceleration around 75 gravity. The main components are body, arm, bucket sample, counter weight, motor, contaminant bottle and computer. The geo-technical sentrifug is equipped with speed sensor, close sensor, stroboscope sensor and vibration sensor. This geotechnical sentrifug was conducted in environmental studies.
