Abstract

Critical thinking skills are essential for addressing 21st-century challenges. In the field of education, learning systems are designed to enhance students' abilities to analyze information, evaluate arguments, and make well-reasoned decisions based on rational and logical thinking. This study aims to examine the differences in the application of Paul-Elder-based student worksheets (LKPD) in improving students' critical thinking skills. This research employed an experimental method, using a control group that received Problem-Based Learning (PBL) worksheets and an experimental group that received Paul-Elder-based worksheets as a special treatment. Critical thinking skills data were collected through pre-tests, post-tests, and student worksheets (LKPD). The results showed that the experimental group experienced a more significant improvement in critical thinking skills compared to the control group. The improvement pattern in the experimental group was more systematic, particularly in problem identification, information gathering, and concept comprehension. However, a decline was observed in the conclusion-drawing stage, indicating that students still struggled to formulate accurate conclusions. Meanwhile, in the control group, critical thinking skills developed but followed a less consistent pattern.

Abstract

Pencemaran udara masih menjadi masalah serius yang dihadapi oleh Negara Indonesia. Pemerintah telah melaksanakan berbagai macam tindakan untuk menyelesaikan masalah tersebut, antara lain memberlakukan uji emisi kendaraan bermotor, penerapan sistem Work From Home (WFH) bagi pegawai di daerah Jabodetabek, penyemprotan jalan raya, penutupan usaha yang berpotensi memperparah pencemaran udara, pembuatan hujan buatan, hingga penyemprotan air dari atas gedung-gedung tinggi. Namun, upaya tersebut masih belum mampu mengatasi masalah pencemaran udara yang terjadi. Oleh sebab itu, dibutuhkan cara lain untuk mengatasinya yaitu dengan cara adsorpsi atau penyerapan menggunakan zeolit alam termodifikasi. Artikel ini membahas tentang penggunaan zeolit alam dan modifikasinya sebagai adsorben emisi gas buang berbahaya dengan tujuan untuk menemukan dan memberikan solusi atas masalah pencemaran udara yang terjadi. Modifikasi zeolit dapat dilakukan dengan senyawa amina, silika, logam, senyawa organik dan pemberian suasana asam. Berdasarkan penelitian-penelitian yang telah dilakukan sebelumnya, zeolit memiliki kemampuan sebagai adsorben gas buang berbahaya. Hal ini dikarenakan zeolit memiliki permukaan berpori. Modifikasi zeolit akan meningkatkan kemampuan adsorpsinya dalam menjerap gas buang berbahaya penyebab pencemaran udara.

Abstract

Material fotokatalisis banyak menarik perhatian karena kemampuannya dalam mendegradasi zat warna berbahaya dalam limbah cair menjadi bahan yang lebih aman. Fotokatalisis adalah proses redoks yang terjadi akibat aktivitas radikal bebas •OH dan •O2- yang terbentuk setelah fotokatalis menyerap cahaya yang sesuai. Salah satu fotokatalis yang sering digunakan, adalah TiO2 yang memiliki aktivitas fotokatalitik cukup baik namun kinerjanya masih perlu ditingkatkan. Salah satu upaya meningkatkan kinerja TiO2 adalah dengan menggabungkan oksida ZrO2 sebagai dopant untuk menghambat laju rekombinasi. Kajian terhadap sejumlah literatur menyatakan bahwa aktivitas fotokatalitik TiO2-ZrO2 masih dapat ditingkatkan efisiensinya melalui peningkatan sensitivitas fotokatalis yang dapat dilakukan dengan berbagai cara. Dari beberapa cara untuk meningkatkan efisiensi TiO2-ZrO2, ada dua yang akan dibahas, yaitu penggunaan templat dalam sintesis dan penggabungan dengan Metal Organic Frameworks (MOFs). Penggunaan templat polimer dalam sintesis TiO2-ZrO2 dapat meningkatkan aktivitas fotokatalitik karena didapatkan luas permukaan spesifik yang besar, porositas tinggi dan fitur optoelektronik yang baik. Sedangkan pada penggabungan dengan MOFs, aktivitas fotokatalitik akan meningkat karena laju rekombinasi dihambat melalui pembentukan heterojunction antara fotokatalis dan MOFs.

Abstract

Bioproduct from microbial enzymatic activities such as biosurfactant, bioacid, biosolvent, and biopolimer is a useful product in improving oil recovery. The nutrient factors such as the difference and variation of the nutrient, influence microbial growth and enzymatic activities. The objective of this study is to examine the feasibility of Stone Medium Salt Solution (SMSS) as a potential nutrient for biosurfactant and biosolvent production on MEOR application. In the tube test, microbial mixed culture and 3 asphaltic crude oils, tested as C1, C2, and C3, were examined in 0%, 25%, 75%, and 100% SMSS concentrations. The microbial activities were determined by pH, viscosity, and interfacial tension measurements under microaerophilic and aerophilic conditions at 0-day and 7-day incubations. The Microbial Core Flooding (MCF) experiment was measured to observe in field application. The microbial consortia in all crudes had good growth using 100 % SMSS medium. After 7 days, the population increased in both microaerophilic and aerophilic conditions. The interfacial tension and viscosity of all crudes decreased except the viscosity of C1 in microaerophilic condition. The highest decrease occurred in C2 crude, which reduced 51% of interfacial tension and 58.73% of viscosity. Although the result of MCF experiment showed insignificant recovery (only 1.63% from Original Oil in Place), this study proves that SMSS nutrient can be applied in MEOR research by ex situ biosurfactant and biosolvent production for enhancing oil recovery.

Abstract

Catalytic cracking process of palm oil into bio-fuel using Ni/zeolite catalysts (2-10% wt. Ni) at various reaction temperatures (400-500oC) in a flow-fixed bed reactor system has been carried out. Palm oil was pre-treated to produce methyl ester of palm oil as feedstock in the catalytic cracking reactions. The Ni/zeolite catalysts were prepared by wetness impregnation method using Ni(NO3)2.6H2O as the precursor. The products were collected and analysed using GC, GC-MS, and calorimeter. The effects of process temperatures and Ni content in Ni/zeolite have been studied. The results showed that Ni-2/zeolite could give a yield of 99.0% at 500oC but only produced gasoline fraction of 18.35%. The physical properties of bio-fuel produced in this condition in terms of density, viscosity, flash point, and specific gravity were less than but similar to commercial fuel. The results of performance test in a 4-strike engine showed that the mixture of commercial gasoline (petrol) and bio-fuel with a ratio of 9:1 gave similar performance to fossil-based gasoline with much lower CO and O2 emissions and more efficient combustion

Abstract

Scientific reasoning in chemistry involves the ability to apply conceptual knowledge in problem-solving, as well as to evaluate issues within broader social, ethical, and environmental contexts. However, conventional assessments often fail to capture this multidimensionality by reducing performance to a single final score. This study uses an integrated learning analytics approach to analyze students’ reasoning performance across two core domains of chemistry learning—applied reasoning and socio-chemical reasoning. A quantitative descriptive design was employed, involving 56 pre-service chemistry teachers who completed four open-ended essay questions, two in each reasoning domain. Student responses were scored using an analytical rubric assessing conceptual accuracy, logical coherence, and justification relevance. Data were analyzed using single-domain and multicomponent strategies, including quadrant profiling, trajectory mapping, clustering, and distribution analysis. Visual tools such as radar charts, spaghetti plots, contour density plots, and alluvial diagrams were used to depict students’ reasoning profiles. Results revealed that most students demonstrated moderate reasoning abilities, although notable inconsistencies were observed between the domains. Individual trajectories exhibited non-linear variations, highlighting diverse cognitive patterns. Clustering and heatmaps indicated distinct learner segments, while alluvial diagrams illustrated transitions between reasoning levels across domains. These findings suggest that students’ reasoning abilities are varied and dynamic. It is concluded that chemistry reasoning is multidimensional and should be assessed through integrated, data-driven methods. The study recommends the adoption of formative, analytics-supported assessments to inform differentiated instruction and promote deeper conceptual and ethical engagement in chemistry education.
