Abstract

The study aimed to investigate the microstructure of natural clay from Pattallassang District, Takalar Regency, South Sulawesi Province. The clay was characterized using X-ray diffractometer (XRD), surface area analyzer (SAA), and scanning electron microscope (SEM). The XRD analysis showed that the main mineral composition of the clay was kaolinite, quartz, hematite, geothite, magnetite, and anatase phases. The SAA using BET analysis shows the large surface area of 59.26 m2/g and BJH analysis for pore distribution of 32.77 nm. SEM observations revealed that the clay consists of plate-like kaolinite particles arranged randomly. The results indicate that the natural clay from Pattallassang District has good potential for use in various industrial applications due to its high kaolinite content and favorable microstructure.Keywords: kaolinite, microstructure, mineral, clay.

Abstract

This work investigated the use of acid treatment on the characteristics of zeolite mineral. The effects of treating zeolite with various acid solutions hydrochloric acid (HCl) and sulfuric acid (H2SO4) were measured using x-ray fluorescence (XRF), x-ray diffraction (XRD), and scanning electron microscope (SEM). The results showed an increase in the percentage of SiO2 and Al2O3 after zeolite activation, and also a decrease in the amount of impurities. The crystalline phase of the zeolite was carried out using XRD analysis, indicating the type of zeolite used is modernite. The SiO2 phase in the sample is quartz, and the Al2O3 phase is corundum. The average crystal size decreased after activation, from 14.23 nm to 6.85 nm for HCl and 5.42 nm for H2SO4. Futhermore, the surface morphology of all zeolite samples has a form of irregular spherical surface, and the surface size of the particles after activation shows a smaller particle shape. The results of this study are expected to become recommendations for further research related to natural zeolite pretreatment as a catalyst support.

Abstract

Keterampilan menulis sangat diperlukan dalam pengembangan ilmu pengetahuan, khususnya bagi tenaga pendidik. Guru di SMAN 11 Pangkep menghadapi beberapa kendala pada proses penulisan artikel ilmiah, seperti kurangnya motivasi dari dalam diri mereka dan kurang memiliki keterampilan dalam menulis artikel ilmiah seperti ketidakpastian tata bahasa serta kurangnya pengetahuan teknis. Pemanfaatan kecerdasan buatan (AI) merupakan solusi yang menjanjikan, memungkinkan guru-guru untuk mengatasi kendala teknis dan meningkatkan kualitas penulisan. Pelatihan dilakukan dengan memberikan pemaparan materi terkait pentingnya menulis artikel ilmiah bagi guru untuk meningkatkan motivasi dalam diri guru untuk menulis. Selain itu, tim pengabdi juga memaparkan materi berupa beberapa aplikasi AI yang dapat digunakan untuk membantu penulisan tata bahasa Inggris, mempermudah parafrase, serta cek plagiasi melalui penggunaan Grammarly, Quillbot, serta Turnitin. Dengan demikian, pelatihan ini diharapkan para peserta dapat menerapkan ilmu yang didapatkannya dalam penulisan artikel ilmiah dengan benar dan dipublikasikan pada jurnal nasional bereputasi.

Abstract

Adanya pandemi Covid-19 di akhir tahun 2019 mengubah pola hidup masyarakat di dunia, salah satunya adalah penerapan protokol kesehatan, seperti  memakai masker dan senantiasa menjaga kebersihan. Dengan demikian, salah satu hal yang wajib dibawa jika ingin berpergian adalah hand sanitizer. Pada kegiatan PKM ini akan diberikan pelatihan pembuatan hand sanitizer berbahan dasar daun kemangi. Mitra kegiatan ini adalah Kelompok PKK yang berlokasi di Kelurahan Samata Kecamatan Somba Opu Kabupaten Gowa. Kegiatan PKM ini dilaksanakan melalui tiga tahapan yaitu, peyuluhan terkait kandungan bahan alam, tahap kedua meliputi peragaan (demonstrasi) pembuatan hand sanitizer berbahan dasar daun kemangi, dan dilanjutkan dengan tahap praktek pembuatan hand sanitizer oleh tim bersama dengan mitra. Setelah mengikuti kegiatan ini, seluruh anggota kelompok PKK Keluarahan Samata mampu mengolah daun kemangi menjadi hand sanitizer alami.
