Telah dilakukan pengukuran gayaberat di daerah Lombok Tengah dan Lombok Timur yaitu dari Jonggat hingga Pringgabaya. Penelitian ini bertujuan untuk mengetahui ketebalan sedimen daerah Lombok Tengah dan Lombok Timur dengan menggunakan analisis spektrum pada data gayaberat. Dalam penelitian ini analisis spektrum dilakukan dengan cara mengubah data dari domain ruang ke dalam domain bilangan gelombang. Pada peta kontur complete bouguer anomaly daerah penelitian dibuat dua macam slicing yaitu slicing horizontal dari arah barat hingga timur daerah penelitian dan slicing vertikal dari arah utara hingga selatan daerah penelitian. Dari slicing arah horizontal didapatkan rata-rata ketebalan residual yang merepresentasikan ketebalan sedimen dari arah utara hingga selatan daerah penelitian sebesar (2154,47±1231,83) meter, sedangkan dari slicing arah vertikal didapatkan rata-rata ketebalan residual yang merepresentasikan ketebalan sedimen dari arah barat hingga timur daerah penelitian (790,73±260,53) meter. Dari nilai ketebalan sedimen yang didapatkan menandakan daerah Lombok Tengah dan Lombok Timur memiliki tingkat keamanan dan ketahanan bangunan terhadap gempabumi lebih besar dibandingkan dengan daerah Lombok bagian utara. Hal ini dapat dilihat dari setelah terjadi gempabumi, kerusakan di daerah Lombok Tengah dan Lombok Timur lebih ringan dibandingkan dengan daerah Lombok bagian utara.

Gold processing waste contains many chemicals compound such as mercury and cyanide, which may help change the physical character of soil. In this study, the temperature, humidity and soil pH has been measured. Measurements of temperature and soil moisture are carried out using SHT11 sensors directly during gold processing. Measurements were carried out around the pond in three different directions. Each direction has 6 points, spaced 5 m apart. Measurements at one point are carried out for 20-21 hours. The measurement results are then mapped to a contour using Surfer-13. Based on the measurement results, obtained temperature values for all points are in the range 25.2-30.3 °C. While the value of soil moisture around 63.8-89.9%, and the soil pH value ranged from 6.8 to 8.1. The mapping results shows the distribution of temperature, humidity and soil pH with almost the same pattern, where the mercury concentration is linear with soil temperature, and soil pH, but non-linear with soil moisture
