Abstract

Air pollution is the condition of air that is contaminated by the presence of materials, substances or polluting components. One of the causes of air pollution is the combustion or inseneration process because the residue of the process can be released into the air. Based on ISPU, there are five main pollutants, namely: carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOX), surface ozone (O3), and dust particles (PM10). This study was conducted to reduce the emission of gases. The use of modified cyclone with adsorbent pipe tube from cocoa husk can increase the efficiency of combustion results with adsorption pipe tube modified cyclone. From the results of the study it was found that emissions from incineration can be controlled with APPU in the form of a cyclone. The use of cyclone alone can reduce NOX and CO levels with a reduction in NOX emissions to 53% and CO to 96%. Both emission reductions are in line with the quality standards. However, the use of adsorption pipe tubes showed better efficiency and effectiveness.

Abstract

Lignoselulosa merupakan suatu sumber daya terbarukan yang jumlahnya sangat melimpah dan transformasinya menjadi bioenergi berpotensi menjadi suatu sarana yang efektif untuk mengatasi kekurangan energi dan daur ulang limbah organik. Mikroorganisme rumen dapat  mengalami reaksi hidrolisis, asidogenesis, dan metanogenesis terhadap biomassa lignoselulosa, terutama yang bergantung pada sinergi mikroorganisme dan enzim. Interaksi mikroorganisme yang berbeda mendorong efisiensi konversi lignoselulosa menjadi energi terbarukan dalam sistem pencernaan mikroorganisme rumen, terutama protozoa dan metanogen. Mikroorganisme rumen dapat mengeluarkan selulase, hemiselulase, dan ligninase, dengan reaksi tersendiri secara sinergis dapat mendorong degradasi lignoselulosa. Struktur substrat terhadap rumen dan sifat aditifnya dapat meningkatkan pencernaan rumen sebagai desain energi yang potensial terhadap biomassa lignoselulosa dalam produksi energi terbarukan. Berbagai produk bernilai tinggi seperti etanol, VFA, MCFA, biogas, dan pupuk organik dapat dihasilkan melalui mikroorganisme rumen terhadap biomassa lignoselulosa, tergantung pada substrat fermentasi bakteri rumen tersebut.

Abstract

This study aims to examine the implementation and impact of using Augmented Reality (AR) in science learning at schools through a literature review approach. The method used is a descriptive-analytical literature review of scientific publications from 2015 to 2025 that discuss the integration of AR in science education at primary and secondary levels. The findings indicate that the implementation of AR enables the visualization of abstract concepts in a more interactive and contextual manner, and strengthens the constructivist approach to learning. The positive impacts of AR on students are evident in improved conceptual understanding, increased learning motivation, and the development of 21st-century skills. Nevertheless, the use of AR requires adequate infrastructure, teacher competence, and well-planned instructional design to ensure its effective and sustainable application.

Abstract

This study aims to examine the application of Green Chemistry principles in science practicum at schools as an effort to achieve safe, environmentally friendly, and sustainable learning. The method employed was a literature review with a descriptive qualitative approach, analyzing scientific articles published in national and international journals. The findings indicate that Green Chemistry can be implemented through the substitution of hazardous chemicals with safer alternatives, the use of micro-scale experiments to minimize waste, and the development of environmentally friendly practicum modules. The benefits include improved students’ science process skills, reduced laboratory accidents, and the development of environmental awareness. Nevertheless, challenges remain, such as limited laboratory facilities, insufficient teacher competence, and the absence of explicit policy support. This review concludes that Green Chemistry plays a crucial role in strengthening contextual, safe, and sustainable science learning that aligns with the demands of 21st-century education Keywords: Green Chemistry, science practicum

Abstract

Masyarakat Desa Girimukti memiliki masalah terkait ketersediaan air bersih, terutama di musim hujan. Menindak lanjuti permasalahan tersebut, Himpunan Mahasiswa Kimia 'AMISCA' ITB melakukan pengabdian berbasis kimia yang diberi nama ALIKUOT. Kegiatan pengabdian yang dilakukan berfokus pada pembuatan zeolit termodifikasi sebagai filter air dan pengembangan berbagai sektor seperti pendidikan dan ekonomi melalui penyuluhan di Desa Girimukti, Sanguling, Bandung Barat. Pembuatan zeolit termodifikasi menggunakan campuran NaCl, karbon aktif, dan Ca(ClO)2, diharapkan dapat menjernihkan air terutama di musim hujan, menyaring berbagai logam berat, serta menghilangkan bau air yang digunakan masyarakat sehari-hari. Pada sektor pendidikan dilakukan edukasi terkait ilmu kimia dan demonstrasi percobaan kimia sederhana. Pada sektor ekonomi dilakukan pengolahan limbah, pembuatan sabun, dan lilin aroma terapi. Metode pengabdian meliputi studi literatur, penentuan masalah, penentuan desa, social mapping, penyusunan program, dan live in di Desa Girimukti. Hasil dari pengabdian ini adalah terciptanya filter air bersih dan masyarakat mendapat pemahaman terkait pengolahan limbah, pembuatan lilin aroma terapi dan sabun. Harapannya melalui pengabdian yang dilakukan dapat membuat air yang digunakan masyarakat menjadi jernih dan layak digunakan serta masyarakat mendapatkan wawasan terkait implementasi ilmu kimia di kehidupan sehari-hari.
