Abstract

The waste management training in Johorejo Village aims to increase public awareness and knowledge, especially PKK women to know about the importance of waste management based on the 3R (Reduce, Reuse, Recycle) principle. The type of research used is a descriptive qualitative approach with data collection through interviews and observations. The subjects of this study are all Johorejo residents. This activity includes the delivery of materials, mentoring, and evaluation. The material presented included waste management, 3R principles, identification of types of waste, and the dangers of indiscriminate waste disposal. The results of the training showed an increase in participants' understanding of waste hazards and a change in attitudes that are more concerned about the environment. Participants began to practice the 3R principles and plan further activities such as the creation of a waste bank and a recycling program in the village. The training proved to be effective in raising environmental awareness among participants, with relevant and practical methods, so that they were better prepared to manage waste responsibly.

Abstract

The analogy is a valuable pedagogical tool for educators because, by using an analogy, abstract concepts in chemistry can be explained effectively. Therefore, prospective educators need to understand analogies. This qualitative descriptive study aims to analyze and describe the analogy used by chemistry education students on the concept of chemical bonds. The test instrument used the form of 10 open-ended questions been validated by anexpert. The results showed three types of analogies: simple analogies, enriched analogies, and extended analogies. This analogy is still single, with the lowest average percentage in the extended analogy type of 5%, while the enriched analogy type is at a percentage of 24%. The analogy type mostly used by students is a simple analogy type with an average percentage of 31 % , and as much as 40% of students do not analogize the existing concept of chemical bonds.

Abstract

Mahasiswa pendidikan kimia sebagai calon guru kimia harus menguasai kompetensi guru salah satunya kompetensi pedagogik. Upaya untuk membekali mahasiswa pendidikan kimia agar memiliki kompetensi tersebut salah satunya dengan membuat soal HOTS (Higher Order Thinking Skills) dalam proses pembelajaran. Penelitian ini merupakan penelitian pengembangan dan bertujuan untuk mengetahui kemampuan mahasiswa pendidikan kimia dalam membuat soal HOTS berbasis multipel representasi. Penelitian dilakukan dengan menggunakan prosedur pengembangan Borg & Gall yang berupa 10 tahap, tetapi dibatasi hanya sampai tahap 7. Pengambilan data dilakukan dengan lembar angket, uji coba soal, dan wawancara. Soal-soal yang dibuat oleh mahasiswa dikategorikan berdasarkan ranah kognitif taksonomi Bloom dan diperoleh 40 soal dengan rincian soal ranah C1 30%, C2 17,50%, C3 15%, C4 22,50%, C5 10%, dan C6 5%. Soal dengan kategori HOTS sebanyak 15 soal (37,50%). Soal  HOTS tersebut dianalisis lebih lanjut dan diperoleh reliabilitas sebesar 0,78 (tinggi) dan 11 soal memenuhi kriteria sehingga dapat digunakan. Kemampuan multipel representasi mahasiswa dalam menyusun soal HOTS mengalami peningkatan.

Abstract

PHBS in schools is a behaviour to empower students, teachers and the community in the school environment to apply and practice PHBS patterns in order to create a clean and healthy school environment. SD Negeri Johorejo Kendal District is one of the elementary schools located in Johorejo Village, Gemuh Subdistrict, Kendal District. This school rarely receives health counselling on PHBS.The purpose of the study was to increase the knowledge of the entire community in the school environment, especially students and teachers regarding the application of PHBS in the school environment and can practice how to wash hands with soap properly and brush teeth properly. This research uses a qualitative approach method. Based on the results of the study, it was found that there were four activities in the socialisation of PHBS at SD Negeri Johorejo, namely the explanation of material about what PHBS is and the benefits of PHBS, hand washing practice, and tooth brushing practice.

Abstract

The rhizome of Temulawak (Curcuma xanthorrhiza Roxb) has been traditionally used to treat various ailments due to its rich content of curcumin, demethoxycurcumin, and bisdemethoxycurcumin. These compounds exhibit notable antioxidant and antibacterial properties. This study aimed to evaluate the antibacterial efficacy of Temulawak rhizome extracts in n-hexane, ethyl acetate, and methanol, focusing on Escherichia coli and Staphylococcus aureus. The extraction process involved successive maceration with each solvent. The antibacterial activity was tested using well diffusion and microdilution methods, determining minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Phytochemical screening revealed the presence of flavonoids, alkaloids, phenolics, steroids, and triterpenoids in the extracts. The results indicated that the n-hexane and ethyl acetate fractions exhibited intense antibacterial activity against Staphylococcus aureus, while all fractions showed potent activity against Escherichia coli. The MIC values ranged from 39.0625 to 625 ppm for Staphylococcus aureus and 39.0625 to 78.125 ppm for Escherichia coli, with MBC values generally higher than MIC values. These findings highlight the potential of Temulawak rhizome extracts as effective antibacterial agents.

Abstract

In modern education, fostering critical thinking skills is essential, enabling students to analyze, interpret, and conclude information effectively. This study evaluates the effectiveness of a guided inquiry learning model integrated with PhET simulations in enhancing students' critical thinking abilities and comprehension of reaction rate concepts. The research was quasi-experimental and assigned to experimental and control groups. The study employed pretest and posttest measures using essay questions to assess critical thinking and conceptual understanding. Results from the t-tests demonstrated significant improvements in both critical thinking (count = 2.240 > table = 1.666) and conceptual understanding (count = 3.064 > table = 1.666) for students engaged in guided inquiry with PhET simulations compared to those in traditional discovery learning settings. These findings underscore the potential of guided inquiry supported by simulations to create an interactive and engaging learning environment, promoting deeper cognitive processing and retention. By merging inquiry-based learning with technological tools, educators can enhance student engagement and facilitate a hands-on approach to complex topics, preparing students for more sophisticated academic and real-world problem-solving scenarios. This study suggests that guided inquiry, complemented by PhET simulations, strengthens conceptual foundations and nurtures critical analytical skills necessary for academic success and beyond

Abstract

Industrial zones with intensive human activities often experience air-quality degradation, particularly in areas surrounding fertilizer production facilities. This study analyzes the concentrations of nitrogen dioxide (NO₂), sulfur dioxide (SO₂), ammonia (NH₃), and oxidants (Ox) in the ambient air around fertilizer industries in Indonesia and evaluates their potential non-carcinogenic health risks. Air sampling was conducted using an InScienPro US-1012 impinger equipped with selective absorbent solutions. Pollutant concentrations were quantified using UV-Vis spectrophotometry based on the Griess–Saltzman method for NO₂, the pararosaniline method for SO₂, the indophenol method for NH₃, and the neutral buffer potassium iodide method for Ox. Concentrations were compared with national ambient air-quality standards. To strengthen the assessment, a quantitative health-risk evaluation was incorporated using the Hazard Quotient (HQ) and Hazard Index (HI), allowing for the interpretation of long-term exposure impacts. Results show that most pollutant concentrations were below regulatory limits; however, SO₂ levels at one sampling point and NH₃ levels near the production zone were elevated. The HQ–HI analysis revealed that SO₂ at the office-area sampling point (HQ = 0.794) and NH₃ inside the processing plant (HQ = 2.238) were the dominant contributors to cumulative exposure, with HI values exceeding 1 at both locations. These findings indicate potential non-carcinogenic risks for individuals chronically exposed in areas closest to emission sources. Overall, this study highlights the importance of continuous monitoring and risk-based evaluation to identify localised hotspots, inform mitigation strategies, and enhance emission control practices in fertiliser-industrial environments.
