Abstract

Indonesia is one of the countries with abundant natural resource wealth including oil, gas and other natural mineral materials. One of the natural mineral materials found on Mandangin Island, Sampang Regency is CaCO3. The purpose of this research is CaCO3 as a substitute for iron sand in concrete mixtures with a variety of places, namely the hamlets of the west and east coasts. To find out the quality of the concrete mixture, an XRF test and a compressive strength test were carried out and compared the CaCO3 mixture which went through the washing and unwashed processes. The results of the XRF test showed that the highest content of the mineral Calcium (Ca) was in the East Coast hamlets of 94.88% and 94.73% in the West Coast. Whereas for the compressive strength test for washed and unwashed variations the highest value was in the washed variation with the highest value level being in the east coast hamlet of 231.17 Kg/Cm2 and west of 176.78 Kg/Cm2. This is a recommendation that CaCO3 sand can be used as a concrete mixture

Abstract

This research aims to examine scientific progress and provide a comprehensive literature review regarding IoT-based sociocultural from 2018 to 2023 using the Scopus database. Additionally, this research aims to identify new concepts and areas of limited knowledge that may require additional investigation. Software from the Scopus website was used for bibliometric analysis. Several citations are used to categorize research findings, which also contain information on author, country, document type, and year of publication. The researchers found eighteen papers by limiting their search to the last six years and using only English keywords. 2021 tops the list of years with the most publications, with five documents. Usually, this category of documents is encountered at international paper conferences. According to this analysis, the number of studies related to IoT-based sociocultural issues in the Scopus database is expected to increase and climax between 2018 and 2023. Various themes and keywords that can form the basis for further investigation have emerged with advances in IoT-based sociocultural research. Future academics will be able to analyze IoT-based sociocultural al changes over the past decades with the help of this bibliographic analysis. To equip ourselves to face future questions, bibliometric analysis provides insights and data related to the progress of sociocultural al research based on the Internet of Things.

Abstract

Research has been conducted into the nature of geothermal rocks in Pamekasan. This place is located in Tlanakan Pamekasan. This study aims to determine the composition of mineral compounds in the soil so that fire can burst out from the soil and the soil does not melt. Three steps can be done with simple refinement and filtering methods, namely X-Ray Fluorescence (XRF), X-ray diffraction (XRD), and Scanning Electron Microscope (SEM). The results of XRF analysis show the element of Api Alam 1 is Ca 66.2%, Api Alam 2 is Si 37.4%, and in hot springs, is Si 39.6%. The XRD results show that mineral qualitatively in Api Alam 1 was in the form of CaCO3 compound at 60.1% and SiO2 at 39.9%, while in Api Alam 2, hot water sources were in the form of SiO2 compound (>90%). SEM Results on Api Alam 1 show that the sample is almost homogeneous (the distribution of CaCO3 and SiO2 is uneven), the presence of slab-shaped clumps that identify the presence of varying grain size, and with high porosity, which indicates that the sample is partially amorphous in structure, in Api Alam 2. The Hot springs show irregular aggregations and poor homogeneity of the sample. The size of the three samples is ten μm or 10.000 nm, while PSA results showed an average size of Api Alam 1 was 509.7 nm, Api Alam 2 was 891.3 nm, and Hot Springs was 468.3 nm.
