Abstract

Guru kimia disyaratkan untuk memiliki 4 kompetensi yang mencakup kompetensi pedagogik, kepribadian, sosial dan profesional. Beberapa keterbatasan guru yang telah teridentifikasi diantaranya adalah masih lemahnya literasi dan kemampuan berfikir kritis, yang menyebabkan pembelajaran kimia lebih bersifat teoritis. Hal ini menjadi salah satu penyebab rendahnya minat dan motivasi siswa untuk mempelajari kimia. Untuk mengatasi hal ini, perlu dilakukan kegiatan penyegaran dan pendalaman materi bagi guru, sehingga diharapkan guru menjadi lebih percaya diri dalam menyajikan pembelajaran kimia yang menarik dan relevan dengan kehidupan sehari-hari. Workshop dilakukan dengan mengadopsi model pembelajaran Problem-based Learning (PBL) untuk memberikan pengalaman kepada guru dalam bertindak sebagai fasilitator untuk memberikan rangsangan kepada siswa dalam mempelajari kimia. Materi termokimia dipilih karena merupakan stimulus yang baik dalam menyelesaikan masalah pada fenomena sehari-hari melalui pengetahuan kimia. Melalui workshop ini, dihasilkan luaran berupa analisis kurikulum serta strategi pembelajaran materi termokimia yang siap diaplikasikan oleh guru.Chemistry teachers are required to have four competencies which include pedagogic, personality, social and professional competencies. Some of the teacher's limitations that have been identified are weak literacy and critical thinking skills, which causes chemistry learning to be more theoretical. This is one of the causes of the low interest and motivation of students to study chemistry. To overcome this, it is necessary to conduct workshop and deepen the material for teachers, so that teachers are expected to become more confident in presenting chemistry lessons that are interesting and relevant to everyday life. The workshop was carried out by adopting a Problem-based Learning (PBL) learning model to provide experience for teachers as facilitators that stimulates students in chemistry learning. Thermochemistry topic was chosen because it is a good stimulus in solving problems in everyday phenomena through chemical knowledge. Through this workshop, outputs are produced in the form of curriculum analysis and learning strategies for thermochemical materials that are ready to be applied by teachers.

Abstract

This article aims to determine the most effective ZnO-zeolite synthesis method for use as an adsorbent. The effectiveness of the ZnO-zeolite synthesis method includes the methods of synthesis, characterization, and adsorption. This study is a literature search using Google Scholar and Science Direct with the keywords “ZnO”, “zeolite”, “synthesis”, and “adsorption” taken from the last 10 years (2013-2023). Twenty-six articles were obtained, and selection was carried out so that 12 articles were obtained. There were 4 methods for ZnO-zeolite synthesis: (1) sol-gel, (2) impregnation, (3) coprecipitation, and (4) hydrothermal methods. The synthesis of ZnO-zeolite products was characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM), and their adsorption capacity was tested via UV-Vis spectroscopy. The hydrothermal synthesis method is the most effective method for the synthesis of ZnO-zeolite because it does not consume a large amount of energy, is a simple synthesis procedure, and has a large adsorption power. The resulting ZnO-zeolite has a crystal size of 1.540 mm and can adsorb up to 657.895 mg/g of the adsorbate).

Abstract

Low rank coal (or lignite) is a low grade, wet, low cost and highly abundant coal. The high moisture content of lignite limits its application as high-heating value fuel and also creates barrier for its export as fuel. However, this property should not necessarily hinder its use in the water industry. Similar to activated carbons, lignite has the theoretical ability to treat the wastewater by adsorbing contaminants from aqueous solution. This review paper highlights the potential use of lignite in wastewater treatment industry.

Abstract

Assessment had a significant influence on students’ learning processes. Assessment needed to continuously align with instruction and existing learning objectives. The goal of science education was to help students develop thinking skills to solve problems in everyday life. This study aimed to analyse the need for an integrated assessment of chemical literacy and critical thinking based on a literature review and empirical data. This study employed a qualitative descriptive method, grounded in a systematic literature review and an empirical field study involving chemistry teachers and high school students studying chemistry subject. The results indicated that the development of integrated assessment test could address the demands of 21st century education, teachers generally recognised the importance of chemical literacy and critical thinking in learning, but still had limitations in utilising appropriate assessment test, and many students still struggled to relate chemistry to everyday life, so their critical thinking skills to address chemical problems in real contexts were not practised through existing test items. These findings highlighted the need to develop an integrated assessment of chemical literacy and critical thinking that not only measured students’ understanding of chemistry concepts but also developed analytical skills to analyse and apply chemical knowledge in real-life situations.

Abstract

Peat soil contains functional groups such as carboxylic acid and hydroxyls that bind metal ions and organic compounds in solution. However, the adsorption capacity of natural peat soil is still considered low. Therefore, this study aims to alter the peat surface using a hydrogen peroxide solution and to utilize the resulting peat as an adsorbent for K+ ions in an aqueous solution. Peat soil was treated with a 10% hydrogen peroxide solution for 30 minutes. The infrared spectra of the treated peat indicated an increase in the intensity of hydroxyl groups (-OH) at 3400 cm-1 and a sharp increase in carboxylic groups (-COOH) at 1700 cm-1. SEM photos showed that the porosity of the treated peat was higher, probably due to oxidation reactions that resulted in new pores on the surface, and BET analysis confirmed the increase in surface area upon treatment. During the adsorption experiment, the residual concentrations of K+ ions were determined using AAS. The adsorption capacities of raw and treated peat were 37.40 mg g-1 and 59.53 mg g-1, respectively. When fitted using Langmuir and Freundlich adsorption isotherm models, the adsorption data plots followed the Freundlich isotherm model, indicating reversible adsorption on heterogeneous surfaces. The Density Functional Theory (DFT) calculation showed that the interaction energy between peat soil and K+ ions was lower after treatment, indicating that K+ ions bind to exchange sites on the treated peat soil.

Abstract

The contamination of antibiotics in water bodies has increased significantly in recent years. Various treatments, including adsorption, have been sought, but most include expensive sorbent material with low efficiency. This research reported an alternative sorbent material; synthetic zeolite derived from coal-burning waste. Coal bottom ash was converted to zeolite via a hydrothermal technique using various concentrations of NaOH and relatively low-temperature conditions. X-ray diffractogram confirms the formation of ZSM-23 when a 1:2 coal-to-zeolite ratio was used at 95°C. The FTIR spectra also highlighted the characteristics of zeolite functional groups, such as the Si−O vibration at 999.56 cm-1 and the Al−O vibration at 799.48 cm-1. The needle-like morphology of ZSM-23 was observed during SEM-EDS analysis. When calculated using BET analysis, the synthetic zeolite also exhibited a high surface area of 433.517 m2 g-1. Upon application in a batch experiment, the maximum adsorption capacity of the zeolite for amoxicillin (AMX) adsorption in aqueous solution was found to be 673.5 mg g-1. The adsorption data fitted the Langmuir isotherm better than the Freundlich one, with a correlation factor of 0.9328. This suggested the monolayer interaction, possibly between the negatively charged zeolite surface and the NH3+ group from AMX. However, the physical adsorption mechanism with the zeolite surface may also occur due to the high surface area. Considering the low production cost, this zeolite offers high economic value as an alternative sorbent for removing antibiotics in water effluent.
