Abstract

A resistivity meter can find out resistivity depth of rock structure, sediment layer, or the depth of water surface. However, the resistivity meter that is often used requires manually recording of the measurement results before inputting them into the processing data software, and this creates many steps in the geoelectric survey. This is because acquiring a resistivity meter with a data storage system entails additional costs, due to its expensive price. Consequently, many of the resistivity meters currently found in laboratories or used in the field are not equipped with a data storage system. This research aims to design a resistivity meter with a data storage system for measurement results, based on Arduino Mega 2560, for laboratory scale. The used sensors were INA219 currents sensor and voltage sensor. In addition, the tests were carried out to determine the level of accuracy of each sensor and testing for data storage system of measurement result. This research employed Schlumberger configuration in the development of resistivity meter. This research has successfully developed a resistivity meter device with a current sensor accuracy level of 97.28% using the INA219 sensor, and a voltage sensor accuracy level of 97.44%. It is noteworthy that the accuracy level is high, and the device is capable of performing readings effectively. This research has successfully designed a resistivity meter which has a measurement data storage.

Abstract

Penelitian ini mengembangkan alat pengukur kadar air kopra dan pH air kolam ikan nila berbasis mikrokontroler yang portabel dan terjangkau. Kelapa (Cocos nucifera L.) sebagai komoditas penting di Indonesia menghadapi tantangan kualitas akibat kadar air kopra yang tidak terkontrol, sementara budidaya ikan nila (Oreochromis niloticus) memerlukan pemantauan pH air (7-8,5) yang akurat. Alat ini mengintegrasikan sensor Resistive Humidity Soil Moisture untuk mengukur kadar air kopra dan sensor pH meter 4502C untuk mengukur keasaman air, dengan data diproses oleh Arduino Uno dan ditampilkan pada LCD. Hasil pengujian menunjukkan sensor resistif memberikan variasi akurasi: overestimate pada kopra kering (selisih hingga 2,63%) dan kelapa basah (3,6-10,26%), serta underestimate pada kopra setengah kering (1,83-3,79%). Sensor pH 4502C memiliki akurasi terbaik di kolam beton (error rata-rata 0,37), diikuti kolam tanah (error 0,138) dan terpal (error 0,138 dengan variasi tinggi). Ketidakakuratan disebabkan oleh kandungan bahan (minyak, elektrolit) dan karakteristik media pengukuran. Alat ini menawarkan solusi praktis bagi petani skala kecil dengan antarmuka sederhana, biaya rendah, dan kemampuan pengukuran real-time. Temuan penelitian menekankan pentingnya kalibrasi spesifik untuk setiap aplikasi guna meningkatkan akurasi pengukuran. Implementasi alat ini diharapkan dapat meningkatkan kualitas produksi kopra dan budidaya ikan nila secara signifikan
