Abstract

Studi literatur untuk mengestimasi temperature reservoir Gunung Lumpur Bledug Kuwu telah dilakukan menggunakan metode geotermometri larutan. Perhitungan temperature diperoleh dari hasil perhitungan empiris kandungan unsure-unsur kimia terlarut pada air panas Gunung Lumpur Bledug Kuwu. Kandungan unsure ini diperoleh dari hasil analisis sampel air panas dengan metode Atomic Absorption Spectrophotometer (AAS) yang dilakukan oleh Rizqiya 2014, berupa konsentrasi Na, K, Ca, Mg dan SiO2. Dari hasil perhitungan ini, estimasi temperature reservoir Bledug Kuwu berkisar antara 90.411 – 148.354 0C.

Abstract

The mathematical modelling of geological structures, i.e. magma intrusion or dyke, has been done,  based on magnetic data with inversion techniques using MatLab. The magnetic equation is a non-linear equation, and completion is done using a linear approach to non-linear mathematical models of magnetic data using the Taylor expansion approach and Jacobi Matrix. The first step of this research is to make synthetic data forward modelling from the magnetic equation of magma intrusion or dyke cases without errors, and the next stepping then add errors to the data. The next step is to do an inversion to get the parameters sought, i.e. depth and angle of the magma intrusion, by giving initial guesses, and then re-correct iteratively until convergent results are obtained. Finally, parameters of slope dyke or thin magma intrusion and its depth can be determined. The results obtained indicate that this technique can be used to get physical parameters sought from magnetic data for simple geological cases, i.e. dyke and magma intrusion.

Abstract

This service aims to provide assistance to the community in the Gubung Serut area to prepare educational natural tourist destinations. Mentoring involves partners from PT. Astra International Tbk., Honda Central Java region. Community empowerment applies a participatory method through the stages of community empowerment through the stages of preparation, implementation, and evaluation. Preparation is carried out through the stages of establishing partnerships to build a shared commitment to developing empowerment programs in target locations. The empowerment program is prepared jointly between the service team, village officials, and target community leaders. Data during the empowerment process and activity achievements were collected through interviews and observations. Interviews reveal the opinion of tourism managers about knowledge gained during empowerment activities and benefits obtained in setting up educational tourism areas. The number of visitors to the tourist area every week has reached more than 100 people. The most attractive tourist destinations for visitors are natural panoramas and educational attractions. Preparing the Gubung Serut tourist area to become an educative natural tourism destination has been carried out through preparing management resources, building destinations, and preparing educational tourist attractions. The development of the Gubung Serut tourist area needs to be done with a broader partnership. The culinary and artistic potential still needs to involve partners more broadly to increase the diversity of tourist attractions that attract visitors.
