Abstract

The adsorption of Bismarck Brown R (BBR) dye has been conducted using mesoporous silica (MCM-48). We synthesized the adsorbent using Ludox HS-40 as a silica source and surfactants of Cetyl Trimethylammonium Bromide (CTAB) and Triton X-100. The characterization of MCM-48 was performed using Fourier transform infrared (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Various contact times were used to study the adsorption kinetics, and concentrations were used to study the adsorption isotherm. The optimum contact time of Bismarck Brown R dye was 120 minutes, and the adsorption followed a pseudo-second-order model. Based on the equation Langmuir and Freundlich adsorption isotherms, the adsorption capacity values of each are obtained 158.7301 mg g-1 and 4.3601 mg g-1. Our results showed that the material can be used as a new dye adsorbent.

Abstract

Artikel ini membahas kontribusi tiga cabang utama filsafat, yaitu ontologi, epistemologi, dan aksiologi, dalam pengembangan kurikulum pendidikan modern, khususnya dalam konteks kurikulum merdeka. Ontologi berkaitan dengan hakikat realitas pendidikan, epistemologi membahas cara memperoleh dan memvalidasi pengetahuan dalam proses pembelajaran, sementara aksiologi mengkaji nilai-nilai etika dan estetika dalam praktik pendidikan. Penelitian menggunakan metode kepustakaan (library research) untuk menganalisis literatur relevan dari berbagai disiplin ilmu. Hasil kajian menunjukkan bahwa integrasi ketiga pilar filsafat tersebut mampu membentuk sistem pendidikan yang menyeluruh, berdaya, inklusif, dan etis. Dengan demikian, artikel ini memberikan pemahaman filosofis yang mendalam dan menawarkan pendekatan konseptual dalam merancang kurikulum yang kontekstual dan berorientasi pada pengembangan karakter peserta didik.

Abstract

The school environment is a place or container for children to be guided in all aspects, morals, knowledge, and skills are very important things to be fostered in the school environment. This study aims to determine the factors in the school environment that can shape children's character, especially in the subject of PKN. This study uses the Qualitative Descriptive method by selecting class V SDN 77 Kanaeng Takalar Regency as a sample and 2 informants who are considered to have knowledge and information about the problem. Data collected using instruments in the form of: Observation and Documentation, as well as in-depth interviews with informants. The data was analyzed qualitatively. The results of this study show quite good results in the Influence of the School Environment on the Formation of Children's Character by interviewing informants seen from the aspects of the influence of educators, students, canteens, classrooms and playgrounds, while educators and students both have positive and negative influences on the formation of children's character.
