Abstract

Research has been conducted regarding the design of a simple Python-based application to transform apparent resistivity values ​​from the Schlumberger configuration into apparent resistivity values ​​from the Wenner configuration using the linear filter method. The application developed was then validated using field data measurements from two different locations, namely Nendali Village in the East Sentani district and Buper Waena in the Heram Jayapura district. At each measurement point, two Vertical Electrical Sounding (VES) measurements were performed using Schlumberger and Wenner configurations. The apparent resistivity values ​​from the Schlumberger configuration were transformed using the application created, and the results were compared with observational data from the Wenner configuration. Field data were taken for as many as six samples per logarithmic cycle, with the Schlumberger AB/2 configuration electrode spacing equal to the Wenner configuration electrode spacing. The maximum stretch lengths in Nendali and Buper villages were 26 m and 40 m, respectively. The research results show a match between the apparent resistivity values ​​of the Wenner configuration obtained from field observations and the transformation results. This suitability was demonstrated qualitatively through the similarity of the apparent resistivity curve trend between the transformed and field observation data. Quantitatively, this suitability is shown by the slope value of the comparison curve of field observation data and transformed data, which in Nendali and Buper Villages is 0.75 and 0.98, respectively. The conclusion of this study is that a simple application that has been designed and created can be used to transform apparent resistivity values ​​from the Schlumberger configuration to the Wenner configuration. A comparison between the transformed data and field observation data shows that suitability is highly dependent on the quality of the field data.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) telah dilakukan di Kampung Abar, Distrik Ebungfauw Kabupaten Jayapura, Papua. Masalah yang dihadapi oleh mitra PkM adalah kesulitan akses sumber air bersih. Air permukaan seperti danau Sentani tidak dapat digunakan karena telah tercemar oleh limbah industri dan rumah tangga, sedangkan mata air yang terletak cukup jauh dari pemukiman warga dan selama ini digunakan sebagai sumber air ternyata tidak berkelanjutan karena mengalami kekeringan pada saat musim kemarau. Salah satu solusi permasalahan ini adalah penggunaan air tanah sebagai sumber alternatif air bersih. Keberadaan lapisan yang mengandung air tanah (akuifer) dapat diduga menggunakan metode geolistrik vertical electrical sounding (VES) konfigurasi Schlumberger. Panjang bentangan dan sampling interval yang digunakan masing-masing adalah 400 meter dan 7 sampel per siklus logaritma. Hasil pengukuran dan analisa VES menunjukkan bahwa lapisan akuifer diduga berada pada kedalaman antara 19 hingga 41 meter dan merupakan rekahan dari Batu Grewak Formasi Makats. Rekomendasi kedalaman ini selanjutnya diserahkan kepada dinas PUPR Kabupaten Jayapura untuk merancang pembangunan infrastruktur air bersih di Kampung Abar.
