Abstract

Scientific literacy is one of the most important aspects in improving the quality of education and human resource development. The level of scientific literacy understanding among students in Indonesia remains comparatively inadequate. Therefore, a chemistry-based community service was conducted at SMAN 30 Garut which aims to improve students' scientific literacy and learning enthusiasm through demonstrations of simple chemical experiments and fun education. This Community Service at SMAN 30 Garut involved members of the HMK “AMISCA” ITB Chemistry Student Association as facilitators in carrying out simple chemical experiments. Several chemical experiments were presented, including the decomposition reaction of hydrogen peroxide, hydrogen balloons, vitamin C testing, secret messages using the Phenolphthalein indicator, and acid-base indicators from colored flower extracts. This activity can improve students' knowledge and interest in science. This is evidenced by the students' enthusiasm in participating in the activities, as well as the results of the feedback distributed after the activities. With the implementation of this chemistry-based community service, it is expected to be a solution in improving scientific literacy and motivating students to further explore the field of science

Abstract

Kersamaju, Cigalontang, Tasikmalaya merupakan salah satu desa yang warganya masih memanfaatkan air sungai sebagai sumber air, sekaligus sebagai tempat pembuangan sampah. Edukasi terkait air tercemar diberikan kepada warga Karang Taruna yang merupakan pionir kemajuan desa yang terdiri dari para warga yang kreatif dan produktif. Selain itu, kegiatan yang dilakukan di masa pandemi menuntut penerapan protokol kesehatan, namun kesadaran warga desa masih kurang dalam menerapkan protokol kesehatan karena belum adanya sarana dan prasarana edukasi warga dalam penerapan protokol kesehatan, seperti mencuci tangan menggunakan sabun atau handsanitizer. Tujuan kegiatan ini adalah memberikan edukasi terkait dampak dan identifikasi air tercemar, serta penerapan protokol kesehatan kepada 20 orang warga Karang Taruna. Metode yang dipilih yaitu forum diskusi dan praktek yaitu praktek identifikasi air tercemar sederhana menggunakan pH universal, pengamatan visual, dan penyaringan air sederhana, serta sosialisasi penerapan protokol kesehatan dengan pembuatan handsanitizer. Kegiatan ini menambah wawasan dan bermanfaat bagi warga Karang Taruna dalam meningkatkan kepedulian lingkungan dan menerapkan protokol kesehatan.

Abstract

A novel magnetic molecularly imprinted polymers (MMIPs) was developed for the adsorption of capsaicin, a key component of capsaicinoids widely used in food additives and topical pharmaceuticals. Excessive use of capsaicin can lead to respiratory, skin, and oral disorders, necessitating effective monitoring methods. This study aimed to synthesize MMIPs and magnetic molecularly non imprinted polymers (MNIPs) using 4-vinyl pyridine as the functional monomer and ethylene glycol dimethacrylate (EGDMA) as the crosslinker, combined with an initiator in a 1:4:20 molar ratio. Magnetite nanoparticles (Fe3O4) were incorporated to facilitate magnetic separation. Characterization via particle size analyzer (PSA), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) confirmed the successful synthesis of Fe3O4 nanoparticles, MNIPs, and MMIPs. PSA analysis for Fe3O4 nanoparticles showed an average size of 140.2 nm with a polydispersity index (PI) of 0.313, MMIPs showed an average particle size of 746.6 nm and a PI value of 0.397. FTIR spectra revealed characteristic absorption bands at 3429 cm−1 (O-H), 2958 cm−1 (C-H), 1732 cm−1 (C=O), 1155 cm−1 (C-O), and 580 cm−1(Fe-O), indicating successful Fe3O4 modification. SEM-EDS analysis showed non-spherical morphology due to bulk polymerization. TEM image results showed Fe₃O₄ nanoparticles were successfully coated with a molecularly imprinted polymer (MIP). The developed MMIPs effectively have a robust synthesis method and thorough analysis, laying the groundwork for future applications.
