“…Sedangkan dalam definisi lain, X-Ray Diffraction (XRD) merupakan analisis yang digunakan untuk mengidentifikasi material kristalit, sebagai contoh identifikasi struktur kristalit (kualitatif) dan fasa (kuantitatif) dalam suatu bahan dengan memanfaatkan radiasi gelombang elektromagnetik sinar-X [6] dan [7]. Selain itu, juga dimanfaatkan untuk mengetahui rincian lain seperti susunan berbagai jenis atom dalam kristal, kehadiran cacat, orientasi, dan cacat kristal [8]. Ketika berkas sinar-X berinteraksi dengan suatu material, terdapat tiga kemungkinan yang dapat terjadi, yaitu absorpsi (penyerapan), difraksi (penghamburan), atau fluoresensi (pemancaran) kembali sinar-X dengan energi yang lebih rendah.…”

Abstract. Calcite mineral is a mineral with a chemical composition of CaCO3 which can be found in a pure state or not. The purpose of this study is to analyze the characteristics of the calcite mineral and recommend its use based on the physical properties of the calcite mineral in the research area, in order to improve the economy of the surrounding area and create employment opportunities. Tests were carried out to determine the characteristics of physical and chemical properties, namely physical properties testing to determine porosity, mass (original, saturated, dependent), weight (original, dry, saturated), apparent specific gravity, true specific gravity, original water content, saturated water content, degree of saturation and void ratio, as well as petrographic thin sections to determine pore type, variety and diagenetic products. Then testing the chemical properties to determine the composition and content of the calcite mineral being tested. In the research area, through testing the physical properties and testing the chemical properties of XRF, it can be seen the characteristics of the mineral calcite which is perfectly crystallized, has orthosparite cement in BGP-1 (10%) and BGP-2 (15%) with poor grain uniformity, fine grained. – medium, the porosity of GMP-01 (3.93%) and GMP-02 (3.25%) and the results of the void ratio of 0.04 cm3 and 0.03 cm3, this value indicates that the rock has a small cavity so that the volume is large. found small. For XRF, it is known that there is 55.84% CaO in the calcite mineral. Abstrak. Mineral kalsit adalah mineral dengan kompisi kimia CaCO3 yang dapat dijumpai dalam keadaan murni ataupun tidak. Adapun tujuan dari penelitian ini untuk menganalisis karakteristik mineral kalsit dan merekomendasikan untuk pemanfaatannya berdasarkan sifat fisik mineral kalsit di daerah penelitian, guna meningkatkan perekonomian daerah sekitar serta membuka lapangan kerja. Dilakukan pengujian untuk mengetahui karakteristik sifat fisik dan sifat kimiawi, yaitu pengujian sifat fisik untuk mengetahui porositas, massa (asli, jenuh, tergantung), bobot (asli, kering, jenuh), apparent specific gravity, true specific gravity, kadar air asli, saturated water content, derajat kejenuhan dan void ratio, serta sayatan tipis petrografi untuk mengetahui tipe pori, faries dan produk diagenesa. Kemudian pengujian sifat kimiawi untuk mengetahui komposisi dan kadar pada mineral kalsit yang di uji. Pada daerah penelitian melalui pengujian sifat fisik dan pengujian sifat kimia XRF, maka dapat diketahui karakteristik mineral kalsit yang terkristalisasi sempurna, memiliki semen orthosparit pada BGP-1 (10%) dan BGP- 2 (15%) dengan keseragaman butir yang buruk, berbutir halus – sedang, porositas GMP-01 (3,93%) dan GMP-02 (3,25%) dan hasil void ratio sebesar 0,04 cm3 dan 0,03 cm3, nilai ini menunjukan bahwa batuan tersebut memiliki rongga kecil sehingga volume yang didapatkan kecil. Untuk XRF diketahui terdapat 55,84% CaO dalam mineral kalsit tersebut.

Soybean is one of the main food commodities in Indonesia. One of the soybean processing that is often consumed is tofu. Inappropriate treatment of tofu liquid waste is very dangerous for life. It is noted that the ammonia content in tofu liquid waste is 23.3-23.5 mg/l which can cause odors that disturb the residents' comfort. One alternative solution for purifying tofu liquid waste is to carry out an adsorption process using coal fly ash. Fly ash contains metal oxides in the form of SiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, K₂O, and Na₂O. The content of SiO₂ as much as 60-70% in it causes fly ash to be very potential to absorb ammonia levels. Extraction of SiO₂ using the sol gel method was carried out using fly ash that had gone through a hydrothermal process. The hydrothermal process is a crystallisation technique in a closed container with high temperature and pressure. After going through the extraction stage, the ongoing process was continued with the washing stage to produce silica powder to adsorb ammonium. The mass required for silica to achieve the optimum ammonia concentration adsorption efficiency is 0.25 gram/20 ml of tofu liquid waste. Meanwhile, the contact time required for silica to achieve the optimum adsorption efficiency of ammonium content is 30 minutes. It was noted that the silica from the optimised fly ash processing had a better quality than the unoptimized silica or commercial silica.

This study aims to determine the effect of combustion temperature on the microstructure and particle diameter of the average silica ash of cocoa shells, and to determine the effect of combustion temperature on the silica content of cocoa shell ash. The method used is experimental through a quantitative approach. The basic material used is cocoa husk (Theobroma cacao) with combustion temperatures of 450, 550, 650, and 750 oC. The tests used to determine the microstructure and silica content of cocoa husk ash were SEM and XRD after which they were analyzed again using Digimizer Software and X-Powder Software. SEM results based on microstructure indicate the occurrence of agglomeration in the cocoa ash silica sample, and it is known that the particle diameter size of sample A = 1,6916 µm, sample B = 0,7824 µm, sample C = 0,7809 µm, and sample D = 0,7173 µm. Based on the XRD results, it can be seen that the silica contained in sample A = 34,8%, sample B = 49,0%, sample C = 65,0%, and sample D = 70,6%. Based on the SEM results, the best results are in the sample which has the smallest size, namely sample D with a particle diameter of 0,7173 µm and based on XRD results the best results are in sample D with the highest SiO2 content of 70,6%. So that the combustion temperature affects the results of SEM and XRD where the effective temperature in the manufacture of cocoa shell ash silica is 750 oC
