Abstract

The processing of gold by means of amalgamation produces mercury wastes. Mercury wastes can pollute the environment. This study aims to determine the diversity of fruit crops and mercury content in the gold mining area of Dusun Mesu. The research method used is survey method, measurement, field observation, and laboratory analysis. The types of plants found are recorded, the number and the diameter. Samples of roots, stems, and leaves of plants were analyzed mercury contents in the laboratory. Based on the results of the analysis, there were 7 types of fruit plants, as many as 32 individuals with the type of vegetation seedling, stake, poles, and trees. The results of calculation of diversity index (H¹), uniformity index (E), and dominance index (C) at all growth rates show low diversity (H = 0.02222 - 0.86648), low uniformity (E = 0.00403-0) , 27959), low dominance (C = 0,0000162 - 0,08). The content of mercury in the soil ranges from 0.001 to 0.044 mg/m³. The content of mercury in fruit crops ranges from <0.0001 - 0.0168%, and soil pH ranges from 4 to 6.8.

Abstract

Traditional medicine in Indonesia has been known to the public long before formal health services with modern medicine. Indonesia has many species of plants that have properties to cure various diseases and some other useful properties for human health. Antipyretic plants are plants that have the property as a febrifuge. The content of flavonoids in plants merit as a reliever fever (antipyretic). This study aims to determine the garden plants that can be utilized by the community as a febrifuge. (antipyretic). The research method used is survey method. The location of the observation and sampling of the plants was done by purposive random sampling technique by plot plot size 2x2 meter, 5x5 meter (adjust the location of the land). Based on research and observation, there are 8 species of antipyretic plants tumeric (Curcuma domestica),  papaya (Carica papaya), dadap (Erythrina sp), hibiscus (Hibiscus rosasinensis), rambutan (Nephelium lappaceum), banana ( Musa  paradisiaca), soursop (Annona muricata), and yam (Pachirrhyzus erosus) which can be utilized by the local community.

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.
