Abstract

Exposure to mercury chloride (HgCl?) is known to induce oxidative stress, which negatively affects the hematological system, including a decrease in hemoglobin levels. This study aims to analyze the effect of honje fruit juice (Etlingera hemisphaerica), known for its high antioxidant content, on hemoglobin levels in mice (Mus musculus) exposed to mercury chloride. This study used an experimental method involving several groups of mice, namely group K1 (control), group K2 (given honje fruit juice), and group K3 (injected with mercury and given honje fruit juice). Hemoglobin levels were measured using a Sahli tube. The results showed that honje fruit juice significantly increased hemoglobin levels in mice exposed to mercury chloride compared to the control group. These findings indicate that the antioxidant content in honje fruit can help reduce the toxic effects of mercury chloride on the circulatory system. Therefore, honje fruit juice has the potential to be developed as a natural therapeutic agent in efforts to mitigate the toxic effects of mercury chloride.

Abstract

Kegiatan pembelajaran daring menuntut guru untuk melakukan berbagai penyesuaian, baik metode maupun media pembelajaran, agar materi dapat tersampaikan dengan efektif kepada peserta didik tanpa memberatkan mereka. Salah satu alternatif media yang dapat digunakan adalah bahan ajar digital berbasis e-modul. Kegiatan pengabdian kepada masyarakat (PPM) ini bertujuan untuk meningkatkan kompetensi guru dalam mengembangkan bahan ajar digital menggunakan aplikasi Canva. Metode pelaksanaan kegiatan terdiri atas tahap persiapan, pelaksanaan pelatihan, dan evaluasi. Tahap persiapan meliputi perizinan, koordinasi dengan mitra, serta penyiapan alat, bahan, soal pre-test dan post-test, serta materi pelatihan. Koordinasi awal dilakukan bersama Kepala Sekolah SDIT Nurul Fikri Kota Bengkulu untuk menyusun jadwal dan teknis pelaksanaan kegiatan. Tahap selanjutnya adalah pelaksanaan kegiatan, sosialisasi diawali dengan pre-test untuk mengukur pengetahuan awal peserta tentang Canva, dilanjutkan dengan sosialisasi dan pelatihan pembuatan bahan ajar digital menggunakan Canva, serta diakhiri post-test untuk mengevaluasi hasil pelatihan. Berdasarkan hasil post-test, seluruh peserta telah mencoba membuat bahan ajar digital dan mengenal fitur-fitur Canva. Hasil pre-test dan post-test menunjukkan adanya peningkatan pemahaman peserta sebesar 95% setelah mengikuti kegiatan ini. Kegiatan ini diharapkan dapat menjadi solusi efektif bagi guru dalam menghadapi tantangan pembelajaran daring yang menarik dan inovatif.

Abstract

The energy crisis due to declining fossil fuel reserves and the increase in organic waste, such as coffee husk waste in Kepahiang Regency, has prompted the need for renewable energy-based solutions. This research aims to develop a science learning module based on the local context through the integration of the concept of pyrolysis of coffee husk waste in the heat and its displacement material. The research method uses the ADDIE model until the validation stage. Data were collected through needs questionnaires and expert validation sheets, analyzed descriptively. The results showed the low interest and understanding of students in the caloric material, as well as the dominance of textual learning methods without direct practice. Most students stated the need for modules that are visual, contextual, and easy to understand. The modules developed are declared valid by experts from the material, linguistic, and graphic aspects. In conclusion, the integrated heat module for coffee skin waste pyrolysis is considered feasible as an innovative teaching material on the concept of heat contextually and applicatively.

Abstract

This study aims to determine the agreement between experimental data from uniform linear motion and uniformly accelerated linear motion experiments using a line-following robot and linear motion theory. The novelty lies in providing empirical evidence on the scientific suitability of line-following robots for representing different types of linear motion. The study validates the robot’s ability to represent GLB, accelerated GLBB, and decelerated GLBB by evaluating the agreement between experimental and theoretical velocity-time (v-t) characteristics before implementation as a physics learning tool. The method involved conducting linear motion experiments, plotting experimental data on v-t graphs, and comparing them with theoretical graphs. Three types of motion were investigated: GLB, accelerated GLBB, and decelerated GLBB. The accelerated and decelerated GLBB experiments were conducted at elevation angles of 13°, 10°, 7°, and 4°. The results show that the GLB and decelerated GLBB experiments generally align with the corresponding motion concepts. The GLB experiment achieved a mean R² value of 1, indicating very high agreement with linear motion theory. Decelerated GLBB achieved a mean R² value of 0.8618, with very high agreement at elevation angles of 10°, 7°, and 4°. In contrast, the accelerated GLBB experiment produced a v-t graph inconsistent with theoretical expectations because the robot’s speed remained nearly constant rather than increasing uniformly. Therefore, the line-following robot is suitable for representing GLB and decelerated GLBB, particularly at elevation angles of 10°, 7°, and 4°. However, it does not adequately represent accelerated GLBB and requires further modification before use for this motion type.
