“…Silica dioxide is a natural mineral that has been used in daily life, such as the main ingredient in the industry of glass, building materials (cement, concrete, ceramics), paper, textiles, electronic devices and paints [1,2]. Generally, silica can be found in rice husks [3], volcanic ash [4], sand [5], mud [6], etc.…”

Silica powder was obtained from the mud volcano of Napan Village following the co-precipitation method. This research aimed to determine the phase changes that occur in calcined silica with various temperatures. This research was carried out in three stages, there are the preparation of a mud volcano using the pre-treatment method, extraction of silica with sodium hydroxy solution, and calcination of silica with temperature variations. By analysis of XRF and XRD results, the mud volcano samples showed a high percentage of SiO2 minerals. The results of silica characterization using XRD showed that uncalcined and calcined silica at 600oC had an amorphous structure with broading peaks. Tridymite and cristobalite phases were detected in calcined silica at 800oC and 1000oC. Calcined silica at a temperature of 1000oC transformed the tridymite phase to cristobalite with a decrease in the intensity of the tridymite phase while the cristobalite phase increased.

“…Thus, this Sidoarjo hot mud has the potential to be used as a source of silica in the future and further exploration can also be carried out due to the presence of soil minerals that were rarely identified. (17). This shows that the coprecipitation method or others can be applied to samples containing silica such as Sidoarjo hot mud to obtain high purity.…”

The Sidoarjo Hot Mud is a phenomenon of mudflow caused by exploration activities of PT. Lapindo Brantas since 2006. The purpose of this article is to provide information related to the empowerment of the Sidoarjo Hot Mud which has the potential as alternative source of renewable energy: source of electrical energy and biodiesel catalyst. Based on XRF results on samples at two locations: the center of the eruption and Lusi Island, it showed that there were various metallic elements and oxide minerals. Based on the results, the Sidoarjo Hot Mud from the center of the eruption resulted in potential difference of 8.8 V and electric power of 7.07135 watts/hour (8 circuits). The hot mud samples of Lusi Island produced potential difference of 4.38 V and electric power of 3.5196 watts/hour (3 circuits); 5.84 V and 4.6928 watts/hour (4 circuits). The silica mineral in the center of the eruption was 45.0% (radius 500 m), 45.3% (radius 1000 m), and 43.3% (radius 2000 m), while on Lusi Island it was 43.8%. Based on these results, the Sidoarjo mud has the potential to be used as a source of renewable energy in Indonesia, as a source of electrical energy and for synthesis for biodiesel catalyst.

The study of the effect of the weight fraction of the filler on the PANi/n-SiO2 composite was carried out in a high salinity medium. Nanosilica (n-SiO2) was synthesized from amorphous silica coprecipitation of Bancar Tuban natural sand using calcination method at 900oC for 6 hours. The synthesized nanosilica was mixed with paint using a variation of filler weight 0.25; 0.5; and 0.75 grams, then coated on SS304 steel. Corrosion experiments consist of two methods, namely polarization to determine the corrosion rate and immersion to identify corrosion products. The experimental results show that the PS50 sample has the lowest rate of 1.04x10-5 mpy
