Abstract

Clean water is one of the basic needs that is needed and is an important concern in a residence for human survival. The condition of the springs is estimated to have experienced a decrease in water quantity due to human activities and changes in quality due to the change of dry and rainy seasons as well as traditional activities. This research aims to determine the quality and quantity of spring water based on physical, chemical and biological parameters based on RI Minister of Health Regulation No. 32 of 2017. These parameters are turbidity, color, TDS, temperature, odor, pH, Nitrate, Nitrite, Cr 2+, Iron, Mn, Total Coliform, E-Coli. The method used is a survey method for sampling and measuring discharge. The results show that the Total Coliform, E-Coli and Temperature parameters exceed the quality standards. This is an indication that there is a result of the dissolution of chemicals from the agricultural activities of local residents as well as the existence of the ruwatan tradition which uses organic materials put into ponds. Water quality that does not meet quality standards will affect public health and the surrounding environment.

Abstract

Siluk Area, Selopamioro Village, Imogiri District, Bantul Regency, Special Region of Yogyakarta, is one of the active community mining sites. These mining activities leave slopes that are not treated or repaired, so that they become a threat to soil and/or rock mass movements for the surrounding community. One of the former mining areas in Siluk hamlet is very close to residential areas. Therefore, it is necessary to study the stability and safety factors of the slope so that they can be the basis for determining the direction of ex-mining slope management.The methods used were literature studies, field surveys and mapping, and laboratory tests. The sampling method used was the purposive sampling method. Samples taken were used for testing physical properties (content weight, moisture content, porosity, and grain size), shear angle, and cohesion. The analysis methods used are the simplified Janbu method and the descriptive analysis method to evaluate the slope of the former mine. Based on calculations and testing, it is found that the three slopes are categorized as steep slopes with a safety factor value on the central and south-north slopes of 0.156, 0.620, and 0.367. Slope management carried out involves a change in slope geometry with the cut and fill method, planting vegetation in the form of Sengon trees, and planting land cover in the form of Vertiver grass
