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

: Rawa Singkil is a former river-lake formed in Pondok and Parangjoro Village, Grogol District, Sukoharjo Regency, Central Java Province due to the straightening of the Bengawan Solo river. Land use and the buildings construction around Rawa Singkil ignore the regulations and river strips. Erosion around Rawa Singkil has the potential to cause siltation. Siltation can reduce the capacity of Rawa Singkil as a reservoir for rainwater runoff to prevent overflow flooding. This study was conducted to calculate the amount of erosion rate, Erosion Hazard Level (EHL) and the effect of rainfall intensity on erosion in Rawa Singkil. The stick method is used to measure the rate of erosion while the intensity of rainfall is measured actually based on the volume and duration of rain using a simple observatory-type rain measuring device. The results showed the largest erosion and EHL in LP-2, LP-3, LP-8, LP-9, and LP-11 respectively, namely: 438.826 tons / Ha / year Weight EHL (BIII); 62,255 tonnes/Ha/year medium EHL (S II); 447,681 tons/Ha/year weight EHL (B III); 57,025 tons/Ha/year light EHL (R I); 488,628 tonnes/Ha/year Very heavy EHL (SB IV). Correlation and regression tests indicate that rainfall intensity and rain duration specifically affect erosion rates

Abstract

The implementation of mining requires employment of protection and management of the affected environment, such as reclamation. The initial stage of reclamation in the form of spreading topsoil serves to prevent land subsidence/erosion. Post spreading area will be left empty for 1 month which causes erosion. This study aims to determine the amount of erosion rate that occurs in the spreading area based on the slope of gentle and sloped slopes and the direction of flow that occurs. The determination of the sampling point was carried out using the purposive sampling method and the measurement of the erosion rate was carried out using the stick method by sticking a stick with a depth of 30 cm with a plot size of 10x10 meters with division of 3 points on the slope of the slope and 3 points on the slope of the gentle slope. Soil sampling is carried out to measure the weight of the volume. Land subsidence measurements were carried out for 19 days for 30 days in each rain event. The calculation of the largest erosion rate on the slope of the gentle slope and the slope was 7,531.29 tons/ha/year and 7,746.44 tons/ha/year respectively which occurred on December 03, 2022., while the smallest erosion rate value on the slope of the gentle slope was on December 15, 2022 of 1,551.6 tons/ha/year and on the slope of the gentle slope was on December 1, 2023 of 1,647.1 tons/ha/year.

Abstract

Hadiwarno Village is one of the regional villages in Pacitan Regency which has a large number of shrimp ponds of around 28.95 hectares. Shrimp ponds have been operating since 2015. Shrimp pond activities have the potential for liquid waste to seep into groundwater, requiring further processing. The purpose of this research was to determine the status of groundwater quality due to shrimp pond waste in the study area. The types of methods used in research are qualitative and quantitative methods. Data collection uses survey and mapping methods. Groundwater sampling using a systematic sampling method with an interval of 15 meters from the shrimp ponds. The data analysis method used is quantitative and qualitative data analysis methods for pollution indices, the relationship between chemical geophysical aspects, problems and impacts from shrimp pond waste. The results showed that the value of the status of water quality in the study area at the three sample points was included in the slightly polluted classification with a pollution index value of 2.1766 to 4.9625
