Abstract

This study aimed to develop a learning multimedia which is based on project-based learning (PjBL) and to investigate its effectiveness in improving students’ higher order thinking skills (HOTS) in the concept of chemistry bonding. This study used a research and development (R&D) design involving the method of Lee and Owen which consisted of five stages namely analysis, design, development, implementation, and evaluation (ADDIE) to develop the intended multimedia. The effect of the developed multimedia use on students’ HOTS was investigated using a one group pretest-posttest experimental design with a class of secondary high school students in Jambi city Indonesia. The research of analysis towards the development process showed that the project-based multimedia learning was successfully developed using the ADDIE method. This involved some validation results from some experts that include the chemistry expert and media learning expert who declared that it was valid and feasible to use. The results of experiments showed that the implemented multimedia was effective in increasing the participant students' HOTS after the learning process. The effectiveness was affirmed by the paired t-test (p-value = 0.000<0.05) indicating that there was a significant difference between the students’ HOTS pretest and posttest. This effectiveness was confirmed by the N-gain value of 0.58 which means that the students had experienced 58% HOTS improvement. This can thus be concluded that the developed project-based multimedia was valid and effective in improving students’ HOTS in the concept of chemistry bonding.

Abstract

Purpose of the Study: This study aims to analyze the impact of the Problem-Based Learning (PBL) model on the development of students’ responsibility character in Chemistry education, with a specific focus on the challenging topic of atomic structure among 11th-grade high school students. Amid increasing concerns about character education in STEM subjects, this study seeks to fill the gap by exploring how active learning models influence affective outcomes alongside cognitive achievement. Methodology: A mixed-methods explanatory design was employed, incorporating a quasi-experimental approach with pretest-posttest control groups. Quantitative data were collected through self-assessment questionnaires, peer evaluations, and teacher observation sheets, while qualitative insights were gathered via semi-structured interviews and thematic analysis of student reflections. The triangulation of data sources provided a comprehensive view of how PBL implementation affects student responsibility. Main Findings: The findings revealed that students in the experimental group demonstrated significant improvements in their responsibility character compared to the control group. Higher posttest scores reflected positive behavioral changes in engagement, discipline, and task accountability during Chemistry learning activities. Qualitative data further supported that PBL encouraged students to take ownership of their learning process, collaborate effectively, and complete tasks with greater autonomy and diligence. Novelty/Originality of this Study: This research offers a novel perspective by applying PBL not only as a cognitive learning strategy but also as a tool for character development in complex Chemistry topics. It advances the understanding of integrative pedagogical models that simultaneously nurture academic proficiency and essential life skills, particularly responsibility, in secondary science education.

Abstract

ABSTRACT. The exploration of naturally occurring secondary metabolites from plants, which serve as direct sources or precursors for new drug development, motivates us to conduct a comprehensive investigation into their presence. Indonesia stands out as a global biodiversity hotspot, boasting a significant number of endemic species that offer a rich reservoir of untapped resources for pharmaceutical, agricultural, and environmental uses. The Dysoxylum genus, belonging to the Meliaceae family, is recognized as a vital source of secondary metabolites and is well-known for its traditional medicinal applications. Consequently, we focus on analyzing the chemical constituents found in the stem bark of one Indonesian Dysoxylum species, specifically D. parasiticum (Osbeck) Kosterm., and assess their biological activity as anticytotoxic agents. Our research identified three known compounds: a tirucallane-type triterpenoid, cneorin-NP36 (1), a seco-limonoid from the preurianin group, amotsangin A (2), and an ergostane-type steroid, 22(E)-ergosta-6,22-dien-3β,5α,8α-triol (3). The biological evaluation against the human breast cancer cell line MCF-7 revealed that compound 2 exhibited a notable inhibitory effect, with an IC50 value of 34.5 μM. The existence of a highly oxidized structure in compound 2, due to its ester substituents, highlights its effectiveness in inhibiting cancer cell proliferation, outperforming the reference drug cisplatin, which has an IC50 of 53.0 μM. These findings indicate that amotsangin A (2) is a promising anticancer agent, particularly in the treatment of breast cancer. Further studies, including in silico analysis and structural modification, are needed to enhance its cytotoxic activity and selectivity. Keywords: Cytotoxic activity, Dysoxylum parasiticum, MCF-7, seco-limonoid amotsangin A, Secondary metabolites

Abstract

ABSTRAKPenelitian ini dilatarbelakangi oleh rendahnya literasi matematis siswa SMP, khususnya dalam memahami, menafsirkan, serta menyelesaikan permasalahan matematika dalam konteks kehidupan nyata. Media pembelajaran yang digunakan di sekolah dinilai belum mampu mengaitkan konsep matematika dengan budaya lokal serta belum memfasilitasi keterampilan pemecahan masalah. Penelitian ini bertujuan untuk: (1) mengembangkan media komik matematika berbasis ethnomathematics melalui model Problem Based Learning (PBL) pada materi Teorema Pythagoras, dan (2) mendeskripsikan kualitas produk ditinjau dari aspek kevalidan, kepraktisan, dan keefektifan dalam meningkatkan literasi matematis siswa SMP. Metode penelitian yang digunakan adalah Research and Development dengan model ADDIE yang meliputi tahap analysis, design, development, implementation, dan evaluation. Subjek penelitian adalah siswa kelas VIII SMP Negeri 19 Kota Jambi. Instrumen penelitian terdiri atas angket validasi ahli materi dan ahli desain, angket kepraktisan guru dan siswa, serta tes literasi matematis. Data dianalisis secara deskriptif kuantitatif dengan uji keefektifan menggunakan perhitungan N-Gain. Hasil penelitian menunjukkan bahwa produk komik matematika berbasis budaya Jambi yang dikembangkan memiliki kualitas sangat valid dengan skor 88%, praktis dengan skor 85%, serta efektif meningkatkan literasi matematis siswa. Rata-rata nilai pretest sebesar 56.4 meningkat menjadi 78,39 pada posttest dengan nilai N-Gain sebesar 0,74 (kategori tinggi). Integrasi unsur budaya Jambi seperti rumah adat, makanan khas, dan kerajinan lokal dalam alur komik berbasis PBL mampu menciptakan pembelajaran yang kontekstual, menarik, dan bermakna bagi siswa. Dengan demikian, komik matematika berbasis ethnomathematics dapat digunakan sebagai media pembelajaran inovatif  untuk meningkatkan literasi matematis siswa SMP. Kata Kunci: komik matematika, ethnomathematics, Problem Based Learning, literasi matematis, budaya JambiABSTRACTThis research was motivated by the low level of students’ mathematical literacy, particularly in understanding, interpreting, and solving mathematical problems in real-life contexts. Learning resources used in schools have not yet connected mathematical concepts to local culture, nor have they supported students’ problem-solving skills. This study aims to: (1) develop a mathematics comic based on ethnomathematics through the Problem Based Learning (PBL) model for the Pythagorean Theorem, and (2) describe the quality of the developed product in terms of its validity, practicality, and effectiveness in improving students’ mathematical literacy. This research employed a Research and Development (R&D) approach using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The subjects were eighth-grade students at SMP Negeri 19 Kota Jambi. Data were collected through material and design expert validation sheets, teacher and student practicality questionnaires, and a mathematical literacy test. The data were analyzed using descriptive quantitative techniques, and effectiveness was measured through the N-Gain formula. The results show that the developed comic meets the criteria of being highly valid with a score of 88%, practical with a score of 85%, and effective in improving students’ mathematical literacy. The students’ average pre-test score of 20.53 increased to 78.39 on the post-test, with an N-Gain score of 0.74, categorized as high. The integration of Jambi cultural elements—such as traditional houses, local cuisine, and handicrafts—within the PBL-based comic storyline successfully created a contextual, engaging, and meaningful learning experience for students. Therefore, the ethnomathematics-based mathematics comic is considered suitable as an innovative learning medium in the Merdeka Curriculum to enhance students’ mathematical literacy.Keywords: mathematics comic, ethnomathematics, Problem Based Learning, mathematical literacy, Jambi culture
