Abstract
Indonesia tengah berupaya mengembangkan beberapa energi alternatif, salah satunya energi panas bumi di daerah Ngebel. Keberadaan sumber energi ini ditandai adanya manifestasi panas bumi seperti mata air panas naik ke atas permukaan melalui rekahan. Pada survey panas bumi, kandungan magnetik batuan dipengaruhi oleh temperatur Curie. Interpretasi data magnetik total secara kualitatif dan kuantitatif dilakukan untuk menganalisa data magnetik. Interpretasi kualitatif dilakukan pada hasil pengolahan data magnetik menggunakan kontinuasi ke atas dan reduksi ke kutub magnet sehingga diperoleh dugaan sesar dan persebaran anomali medan magnet daerah penelitian. Selain itu, dilakukan interpretasi kuantitatif menggunakan metode continuous wavelet transform (CWT). Sehingga diperoleh kedalaman dua rekahan masing-masing 363.59m dan 34.96m. Kemenerusan hasil interpretasi anomali menggunakan reduksi ke kutub serta analisa CWT menunjukkan kesesuaian sesar dengan peta geologi dari arah Selatan menuju Utara.

Alternate energy is being developed by Indonesian researcher, one of the research is geothermal in Ngebel. The existence of this energy source has indicated by geothermal manisfestations, such as hot springs that rise to the surface through the fractures. Geothermal survey found that magnetic substrate of mineral have influenced by Curie’s Temperature. Total magnetic data have been interpretated qualitatively and quantitatively to analyze data. Qualitative interpretation is done with determine the upward continuation and magnetic pole reduction, its purpose to suppose the faults and magnetic anomaly distribution area. In the other hand, quantitative interpretation is also done with Continous Wavelet Transform (CWT) method. For the results, faults depth have been obtained are 363.59m and 34.96m. the interpretation result of anomaly which have been done by pole reduction and CWT analyze show the faults suitability from Sauth to North.
