Abstract

Situ Cisanti located at Tarumajaya Village, Kertasari District, Bandung Regency, West Java. Situ Cisanti has significant role in supporting the lives of the surrounding community, especially as the central source of clean water. This research was conduct to identify the water quality of Situ Cisanti by mapping the parameters of pH, Electrical Conductivity (EC), and Total Dissolved Solids (TDS). Measurement was take using Combometer Hanna Grocheck HI 9813-6 at 69 points spread over the research area. The result of pH measurement in Situ Cisanti has a range value from 7,7 to 9,7 with an average value of 9. The EC measurement range value is 0,1 mS/cm to 0,9 mS/cm with an average value of 0,13 mS/cm. The TDS measurement range value is 83 mg/L to 141 mg/L, while the average is 100,78 mg/L. Most of the pH values in the study area meet the quality standards for hygiene sanitation water, while the EC and TDS values are below the threshold value, considering it safe for health.

Abstract

Noise recorded during measurements can diminish the quality of AMT data. This can lead to decreased penetration depth and unreliable 1D inversion models. This study aimed to reduce noise and improve data quality by analyzing coherence, curve trend, and skewness. Coherence analysis was performed using robust processing and XPR editing, yielding an average coherence value of 77.5%, an improvement of 10.8% from the raw data. Noise can also alter data dimensionality; hence, skewness analysis was used to determine the effect of distortion on the impedance tensor. Results showed that the 3D dimensionality effect at 6 stations was significantly reduced following coherence and curve trend analyses.

Abstract

Situ Cisanti merupakan salah satu tempat pariwisata dan edukasi yang terletak di Desa Tarumajaya, Kecamatan Kertasari, Kabupaten Bandung. Situ Cisanti memiliki tujuh mata air yang berperan besar bagi masyarakat sekitar sebagai sumber air. Penelitian ini memetakan topografi dasar perairan melalui peta batimetri serta melakukan simulasi perubahan muka air Situ Cisanti. Akuisisi dilakukan menggunakan instrumen Deeper Smart Sonar Pro+ dengan bantuan aplikasi Fish Deeper untuk visualisasi data. Hasil dari pemetaan batimetri Situ Cisanti menunjukkan kedalaman kolom air yang bervariasi antara 0,3 m sampai 2,85 m dengan rata-rata kedalaman sebesar 1,1 m. Sedangkan hasil simulasi muka air Situ Cisanti ditampilkan dalam beberapa keadaan, yaitu keadaan normal setinggi 2,85 m dari batas air dan sedimen, serta ketinggian muka air yang ditambahkan sebesar 0,5 m dan 1 m. Jika muka air di Situ Cisanti bertambah melebihi normal, maka bagian Timur dan Selatan dari Situ Cisanti akan terkena dampak terlebih dahulu dan akan menyebabkan adanya genangan di area tersebut.

Abstract

The Malabar Mountains area acts as a catchment and infiltration zone for rainwater. Haruman Peak is the location of one of these areas. Information on the well-preserved depth of the shallow aquifer at 40 meters reinforces this. This research reviews the results of subsurface 1D resistivity structures from AMT data to obtain information on the depth of deep aquifers on the western slope of the Haruman Peak Lava Fan, Haruman Mountains. 1D modelling shows an aquifer at depth of 140.56-2080.07 meters with resistivity ranging from 5.25-68.08 Ωm. At depths of 453.32 m (HR02), 530.8 m (HR03), 1464.97 m (HR01), and 2080.07 m (HR02), interbedded tuff-andesite with minor pumice identifies the deep aquifer. In addition, a depth of 140.56 m (HR02) with a resistivity value of 68.08 Ωm indicates a shallow aquifer. Looking at the elevation of the Bandung Basin, water from aquifers located at elevations > 700 meters above sea level will flow into the Bandung Basin.
