Abstract

Pandan volcano is a volcano formed on Tertiary sedimentary rocks from the Kendeng zone deposited in the basin of East Java. In addition to generating petroleum potentials, such as Cepu and Bojonegoro oil fields, this area also generates geothermal potential. As a source of heat from the geothermal system is igneous rock formed from the magmatism process. The type of rock formed by the process of magmatism in the Pandan geothermal system is basaltic-andesitic and hornblende andesite are medium-high K calk alkaline affinity located in the island arc. The interaction of hot rock from post magmatism process with hydrothermal fluid resulted in the manifestation of hot springs and calcite travertine in the study area. Prediction of the subsurface temperature of hot water from geothermometer silica analysis contained in Banyukuning and Jarikasinan show cristobalite Beta equilibrium (70oC) and quartz temperature (120oC). To study about magmatism and geothermal fluid using petrographic method and petrochemical analysis (X-ray fluorescence spectrometry method) to the sample of igneous rock. While to study the fluid type and geothermometer of geothermal fluid using data from previous researchers. This research study is expected to provide additional information on the field of geothermal and magmatism in this area.

Abstract

Terminologi lumpur sidoarjo (Lusi) sebagai sebuah gunung lumpur saat ini sudah tidak relevan lagi. Berdasarkan analisis geokimia menunjukkan bukti-bukti jejak gunung api pada Lusi dan sudah berkorelasi positif, sehingga Lusi dapat dikatakan sebuah sistem hidrotermal pada cekungan sedimen. Sistem hidrotermal selalu berkaitan dengan pengkayaan mineral terutama pada lapisan lempung. Fluida geotermal bersifat asam, potensial melarutkan unsur logam,  sehingga kandungan unsur pada lumpur akan terpengaruh. Lusi termasuk ke dalam sistem endapan epitermal sulfida rendah (low ephitermal sulfide) dengan zona ubahan argilik yang ditandai oleh pembentukan mineral lempung yang bertemperatur rendah seperti kaolinit, smektit dan illit Adanya sistem hidrotermal yang bekerja pada Lusi dengan karakteristik tersebut membuat Lusi memiliki peluang untuk pengkayaan unsur tanah jarang. Hasil analisis laboratorium menggunakan metode ICP dan XRF didapat konsentrasi pelimpahan unsur tanah jarang seperti Ce, Dy, Eu, Gd, La, Nd, Pr, Sc, Sm dan Y  yang relatif tinggi.

Abstract

Dental fluorosis is a disorder of mottled or mottled enamel structure as a result of excess fluoride intake during tooth formation. Water is one source of fluorine. The purpose of this community service is to assist the community in improving dental health and preventing dental and bone fluorosis. The implementation of this community service uses lecture and discussion methods. The stages of this service include pretest, delivery of material, post test, and discussion sessions. Post test results show an increase in community knowledge. It is hoped that this increase in knowledge can be applied by the Mojosari village community in an effort to procure water to meet their needs. Keywords: fluorosis, fluorosis, Mojosari village
