Abstract

This research aims to produce a POGIL-based interactive chemistry e-module for chemistry learning in chapter stoichiometry or chemical calculation. This type of research is Research and Development (RnD) and the Borg and Gall development model. The subjects of this research were XI grade high school students. Product validation was carried out by material and language and media experts. The application used is Flip PDF Professional. The product trial was conducted at SMAN 71 Jakarta. The results showed that: (1) Expert assessment related to material aspects amounted to 85% with good interpretation, language aspects 85.83% good interpretation, and media aspects 82.21% good interpretation. (2) Assessment by teachers on a small and large scale as a whole increased, namely 94.91% on a small scale and 99.22% on a large scale with very good interpretation, and assessment by students as a whole also increased, namely 82% on a small scale and 83.50% on a large scale with good interpretation. It can be concluded that the e-module developed is very good and feasible to use as teaching material in the classroom and the students' independent learning process.

Abstract

Background: Madrasah Aliyah (MA) menghadapi tantangan berupa keterbatasan waktu pembelajaran dan sarana praktikum yang berdampak pada optimalisasi pembelajaran kimia. Pemanfaatan e-modul berbasis STEM dan etnosains menjadi alternatif inovatif, namun implementasinya masih memerlukan penguatan kompetensi guru. Kegiatan pengabdian ini bertujuan meningkatkan kompetensi guru kimia MA yang tergabung dalam MGMP Kimia Jakarta melalui pelatihan dan pendampingan implementasi e-modul generasi keempat berbasis STEM-POGIL, STEM–Case Based Learning, dan etnosains pada materi laju reaksi, koloid, dan larutan penyangga. Metode: Kegiatan pengabdian kepada masyarakat ini dilaksanakan melalui pendekatan blended learning berupa pelatihan, diskusi kelompok terarah (FGD), dan pendampingan kepada guru kimia Madrasah Aliyah yang tergabung dalam MGMP Kementerian Agama DKI Jakarta. Materi meliputi penggunaan e-modul kimia generasi keempat berbasis STEM-POGIL pada materi laju reaksi, STEM–Case Based Learning pada koloid, serta pendekatan etnosains pada larutan penyangga. Evaluasi dilakukan menggunakan pre-test, post-test, serta kuesioner tertutup dan terbuka. Hasil:  Hasil menunjukkan peningkatan pemahaman yang signifikan, ditandai dengan dominasi skor post-test sebesar 100% pada sebagian besar indikator dibandingkan pre-test yang masih berada pada rentang 60–70% pada beberapa butir, serta tidak adanya peserta dengan skor di bawah 60 pada akhir kegiatan. Tingkat kepuasan peserta juga berada pada kategori sangat baik (88,3–98,3%), terutama pada aspek penguasaan materi narasumber (98,3%) dan pemahaman materi (97,2%). Kesimpulan: Meskipun demikian, implementasi di sekolah masih menghadapi kendala infrastruktur dan kebijakan internal, sehingga diperlukan pendampingan berkelanjutan untuk memastikan penerapan e-modul berbasis STEM dan etnosains secara lebih merata dan berkelanjutan.

Abstract

Foodborne illnesses remain a public health concern in Indonesia, prompting the search for natural antibacterial agents. This study evaluated the antibacterial activity and chemical profile of Nannochloropsis oculata extracts against Listeria monocytogenes and Shigella flexneri. Microalgae were cultivated, and cell density was monitored using an Ultraviolet–Visible (UV–Vis) spectrophotometer. Biomass was harvested and extracted using chloroform–methanol, followed by compound identification through Gas Chromatography–Mass Spectrometry (GC–MS). Antibacterial activity was assessed using the disc diffusion method. A total of 1.3196 g of dry biomass was obtained. At 200 mg/mL, the extract produced inhibition zones of 8.40 ± 0.17 mm against L. monocytogenes and 8.83 ± 0.29 mm against S. flexneri. GC–MS analysis revealed fatty acid derivatives, predominantly methyl palmitoleate (26.47%). These findings provide preliminary insight into the antibacterial potential of N. oculata extracts; however, further quantitative and application-based studies are required to determine their practical relevance.

Abstract

Shigella flexneri can cause shigellosis, which results in high fever, vomiting, diarrhea, or death. This study developed a detection method based on real-time polymerase chain reaction that targets the sfmD gene of S. flexneri given that the virulence factor encoded by this gene is thought to facilitate adhesion to a host surface. The proposed method involves primer design, DNA isolation, the optimization of primer annealing temperature, and confirmation, specificity, and sensitivity tests. A sfmD primer with an amplicon length of 155 bp was annealed to the target DNA at an optimized temperature of 60 ℃ (range 54 °C–62 °C). This primer pair amplified the target sequences at a cycle threshold (Ct) of 15.11 ± 0.38 and a melting temperature of 82.41 ± 0.01 ℃. The primer specificity test showed that the primer distinguished S. flexneri from nontarget bacteria. The findings also revealed that the primer detected S. flexneri down to a limit of 16 pg/μL at a Ct of 26.68, equivalent to 2.79×102 CFU. Overall, the sfmD primer can effectively amplify S. flexneri DNA. Future research can be directed toward the detection of S. flexneri in artificially contaminated food samples to validate the real-food applicability and strengthen its potential use in food safety monitoring and clinical diagnostics.

Abstract

Practicum is essential to learning because it provides practical learning opportunities in building students' knowledge. Learning using the practical method can explain abstract theories into concrete ones and can be analyzed in more detail so that this method can improve cognitive, psychomotor, and affective skills. Practical activities in schools currently still use large amounts of chemicals. The resulting waste is only thrown in the trash or the drain. Disposal of large amounts of chemical waste will affect the surrounding environment. Based on this background, the researcher aims to develop a small-scale practical kit and flipbook for instructions on practical acid and base solutions. This type of research is development research (R&D) and uses the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). Material and language experts and media experts validate products. Product trials were carried out at SMAN 15 Tangerang Regency. The results of the validation of the small-scale practicum kit and flipbook practicum instructions were material 87% (very feasible), language 80% (feasible), and media 84% (very feasible). The product trial results stated that the small-scale practical kit and practical flipbook instructions were suitable for use in the learning process
