Abstract

Physalis angulata and Moringa oleifera have long been the key ingredients of traditional medicine. This study aimed to obtain the metabolite profiles of the ethanolic leaf extracts of P. angulata (ELP) and M. oleifera (ELM), evaluate their antioxidant activity, and assess their toxicity against normal and cancer cells. The leaves were sourced from Balittro, West Java. The extraction used 70% ethanol and continued for 3 days. The metabolites were identified using Gas Chromatography-Mass Spectrometry (GC-MS), antioxidant activity was ascertained via the DPPH assay, and cytotoxicity was evaluated employing the PrestoBlue assay. GC-MS identified 23 compounds in ELP and 15 in ELM. The DPPH assay showed that ELM, ELP, or their combination exhibited marked antioxidant activity, with inhibition ranging from 50% to 90%. The toxicity assay against MCF-7 cancer cells demonstrated that ELP at 1,500 µg/mL and ELM at 1,200 µg/mL induced cytotoxicity. The ELP + ELM formulation exhibited stronger cytotoxic effects than the positive control. In contrast, ELM or ELP did not induce toxicity in normal CV-1 cells and, stimulated viability com-pared to the control. Thus, the phytochemical contents of ELM and ELP exhibited enhanced antioxidant activity, in-duced toxicity in cancer cells, and were safe for normal cells.

Abstract

Kemampuan Habits of Mind, Emotional Intelligence, dan penguasaan konsep dapat dilatih, dikembangkan, dan ditingkatkan melalui suatu model pembelajaran. Penelitian ini bertujuan untuk mengetahui peningkatan Habits of Mind, Emotional Intelligence, dan penguasaan konsep siswa SMA melalui implementasi Problem Based Learning. Metode yang digunakan dalam penelitian ini adalah weak experiment dengan desain penelitian one-group pretestposttest yang dilakukan di kelas XI IPA 1 SMAN 1 Rengat Riau. Pengumpulan data dilakukan melalui angket Habits of Mind awal dan akhir, angket Emotional Intelligence awal dan akhir, soal pretest dan posttest materi sistem ekskresi dan sistem saraf. Analisis data penelitian menggunakan nilai normalisasi gain. Hasil penelitian menunjukkan bahwa kemampuan Habits of Mind siswa setelah implementasi Problem Based Learning mengalami peningkatan dengan N-gain sebesar 0,53 berada dalam kategori sedang. Sejalan dengan itu, kemampuan Emotional Intelligence siswa juga mengalami peningkatan dengan N-gain sebesar 0,33 berada dalam kategori sedang. Kemampuan penguasaan konsep siswa pada materi sistem ekskresi mengalami peningkatan dengan N-gain sebesar 0,66 berada dalam kategori sedang, sedangkan pada materi sistem saraf mengalami peningkatan dengan N-gain sebesar 0,84 berada dalam kategori tinggi. Dapat disimpulkan bahwa implementasi Problem Based Learning dapat meningkatkan kemampuan Habits of Mind, Emotional Intelligence, dan penguasaan konsep siswa. Peningkatan kemampuan Habits of Mind, Emotional Intelligence, dan penguasaan konsep siswa di atas nilai standar 0,31 (N-gain sedang).

Abstract

In cell material, many concepts are abstract and can cause students to experience difficulties in understanding them. Every concept in biology learning is interconnected so that every concept that is built can influence the formation of the next concept. However, often students' initial concepts are misconceptions, namely the concepts possessed by students conflict with the concepts raised by experts. A good learning experience is needed so that students can understand the concept correctly. One learning model that provides a learning experience to discover and understand concepts is the Think Talk Write learning model. The purpose of this research is to remediate misconceptions about cell material by using the Think Talk Write learning model. This study used an experimental method with the type of pre-experimental research and one-group pretest-posttest research design. The subjects in this study were students of class XI IPA at SMA Muhammadiyah 5 Rancaekek consisting of 36 students. Based on the results of data processing, it was found that misconceptions in the pretest resulted in 12.78% and in the posttest it decreased to 6.25%. So it can be concluded that the Think Talk Write learning model can reduce students' misconceptions about cell material.

Abstract

This study aims to develop an E-Module to train high school students' reading literacy skills. The e-module was designed using Canva-assisted power point and saved in power point show. The power point show is then sent via WhatsApp for students to use. This research uses the development method with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) according to. The implementation phase uses a pretest – posttest non-equivalent control group design to obtain information about the effect the developed E-Module. This research was conducted at a public high school in Cimahi City, West Java Province in February-March 2023. The sample for this study was taken by convenience sampling , namely 30 students from class XI IPA 1 as the experimental class and 30 students from class XI IPA 2 as the experimental class. control. The instruments and data collection techniques used in this study were the due diligence validation sheets, readability tests and reading literacy skills tests. The results showed that the feasibility test for the developed E-module showed very feasible criteria, the readability test showed a result of 80% with easy-to-understand criteria and the development of this E-module could increase reading literacy skills by 0.7 with high criteria on the indicator of finding information, 0.8 with high criteria on indicators of interpretation and integration and a score of 1 with high criteria on evaluating and reflecting indicators.
