Abstract

Air tanah sebagai air bersih merupakan salah satu kebutuhan primer manusia yang dimanfaatkan dalam berbagai kepentingan manusia serta untuk air minum. Airtanah memiliki kualitas dimana salah satu parameter fisiknya adalah daya hantar listrik (DHL). Dalam suatu Cekungan Airtanah (CAT), airtanah memiliki keberagaman nilai daya hantar listrik yang dipengaruhi oleh faktor infiltrasi dan lingkungan. Nilai DHL dapat dijadikan suatu acuan mengenai kelayakan suatu airtanah sebagai air minum. Sebagai salah satu sumber yang paling diminati masyarakat, maka masyarakat juga perlu untuk mengetahui kualitas dari airtanah tersebut melalui parameter daya hantar listrik sehingga peta daya hantar listrik daerah CAT Sumowono dapat menjadi suatu informasi bagi masyarakat yang menggunakan airtanah dari CAT Sumowono tersebut. Maka dari itu perlu adanya pembuatan peta daya hantar listrik daerah CAT Sumowono agar masyarakat merasa nyaman dan aman dalam memanfaatkan airtanah. Metode interpolasi data DHL menggunakan analisis geostatistik yang terdapat pada perangkat lunak ArcGIS 10.3. Metode interpolasi yang digunakan adalah Inverse Distance Weighting (IDW), Radial Basis Functions (RBF) dan Empirical Bayesian Kriging (EBK). Dari keseluruhan data yang terinterpolasi, didapatkan dua kelas kualitas airtanah berdasarkan nilai DHL, yaitu Sangat Baik (<250 μS/cm) dan Baik (250-750 μS/cm). Metode interpolasi yang dinilai paling seimbang adalah metode RBF. Melalui peta DHL hasil interpolasi metode RBF diketahui persebaran daerah dengan kelas sangat baik pada daerah CAT Sumowono mencakup 52,8% dari luas CAT dan 47,2% masuk ke dalam kelas baik.

Abstract

Groundwater management at groundwater basins Sumowono needs to be done because of the increasing development of the area. This research is oriented to analyzing groundwater conditions, compiling groundwater conservation zones, and explaining conservation zones' suitability with spatial maps. The method used is mapping hydrogeological conditions such as surface observation of rock types, inventory of hydrogeological points of interest, knowing the patterns and directions of groundwater flow, groundwater utilization, and groundwater sampling to measure the degree of acidity and electrical conductivity. From the mapping results, it is found that the lithology is composed of tuffaceous sandstones and volcanic breccias. Based on the free groundwater table analysis, the free groundwater flow pattern follows the topographic slope, flowing from the high topography on the south and southeast sides to the low topography on the north side of the area. The utilization of groundwater is used for irrigation, domestic and fishery purposes. Measurement of groundwater samples' quality for the degree of acidity is between 5.32-7.98 while the electrical conductivity is between 36-550 µS / cm, and the level of damage due to groundwater utilization is included in the safe zone. The groundwater conservation zone consists of recharge areas and spring protection zones. The result of overlapping between the groundwater conservation zone and the spatial plan map shows suitability as a protection zone.

Abstract

The Sumowono Groundwater Basin is a cross-district basin located in Central Java Province, between Temanggung Regency, Kendal Regency, and Semarang Regency. The people in this area obtain fresh water from either dug wells or springs. The purpose of this research is to determine the feasibility of groundwater for drinking water and irrigation purposes. The method used was hydrogeological mapping and physical and chemical analysis of 10 groundwater samples. The samples were subjected to empirical testing of the Groundwater Quality Index to determine the feasibility of drinking water and irrigation using Sodium Adsorption Ratio (SAR) analysis and Wilcox diagram. The results showed that all samples physically have tasteless and odorous properties. For the chemical properties produced in the ten samples, the pH value ranges from about 6.85 - 7.27. The electrical conductivity is between 71.6 - 511 µS/cm. Total Dissolved Solids values are between 45.82 and 327.04 mg/L, with total hardness values ranging from 10 to 170 mg/L. From the results of the SAR analysis, it is found that the groundwater classes were included in S1C1 and S1C2, so that groundwater has low alkaline in both sodium and salinity, respectively. Thus, groundwater is considered suitable for consumption and irrigation purposes,

Abstract

The annual increase in population leads to a growing demand for water. To control groundwater utilization in a directed manner is to extract groundwater according to groundwater potential. The research aims to analyze the groundwater potential in the Jakarta Groundwater Basin in terms of quantity and quality. The method used is primary data analysis by determining quantity potential using the Darcy equation method with additional calculations of groundwater volume and quality potential based on drinking water quality standards from the Republic of Indonesia Minister of Health Regulation no. 2 of 2023 and WHO of 2022. The dynamic potential for unconfined aquifers ranges from 2,663–1,372,901 m³/year, while for confined aquifers range from 184,991–1,895,288 m³/year. The static potential for unconfined aquifers ranges from 266,852–3,252,654 m³, while for confined aquifers ranges from 1,317,862–30,620,266 m³. Based on groundwater quality standards for drinking water from the Minister of Health and WHO for the parameters pH, TDS, Na⁺, Cl⁻, SO₄²⁻ and NO₃⁻, there are 15 samples from 53 samples of unconfined aquifer and 36 samples from 75 samples of confined aquifer that meet standards.

Abstract

The amount of available water is becoming more scarce due to increased human demand. As a result, people are now obtaining their water from limited aquifers or deep groundwater from artesian water sources. Nonetheless, the varied properties of the soil and rocks within it do not ensure that the groundwater's quality remains safe from microorganisms or germs. Coliform, one of the bacteria or microorganisms that can increase in groundwater due to variations in the rock lithologies found in different regions. Analysis of coliform bacteria distribution was carried out in 30 drilled wells from confined aquifers spread across the city of Semarang. This research identified total coliforms using the Most Probable Numbers (MPN) method. The presence of coliform bacteria in certain wells was compared with the characteristics of rocks, where in this study area there are several rock lithologies such as volcanic breccia, andesite, pyroclastic breccia, lava, and clay. As for the results of this analysis, it was found that 10% of the samples contained total coliforms that exceeded the maximum limit of 50 CFU/100 ml, where the lithology with the highest total coliform content was found in the basalt area with the highest results, namely TNTC (Too Numerous to Count).
