Abstract

Program pengabdian ini bertujuan meningkatkan produktivitas dan stabilitas ekonomi petani melalui penerapan sistem pertanian terintegrasi antara budidaya kelapa dan ikan lele di Desa Bubuhan, Kabupaten Simeulue. Kegiatan ini dilatarbelakangi oleh rendahnya hasil produksi kelapa dan belum optimalnya pemanfaatan sumber daya lokal. Metode yang digunakan adalah pendekatan Asset-Based Community Development (ABCD) dan Community Development, yang dilaksanakan dalam tiga tahap: (1) sosialisasi konsep budidaya terpadu; (2) pendampingan praktik lapangan mencakup integrasi budidaya kelapa dan lele serta pemanfaatan limbah kolam menjadi pupuk organik cair; dan (3) evaluasi partisipatif dan sumatif. Hasil evaluasi partisipatif menunjukkan bahwa pemahaman awal petani terhadap konsep integrasi dan pengolahan limbah masih rendah, namun 95% menyatakan optimisme tinggi terhadap potensi peningkatan pendapatan. Setelah pelaksanaan kegiatan, evaluasi sumatif menunjukkan peningkatan signifikan, sebanyak 87% petani memahami sistem integrasi, 100% mampu memfermentasi limbah lele menjadi POC, dan seluruh peserta termotivasi menerapkan sistem secara mandiri. Selain itu, 80% responden mengakui adanya peluang diversifikasi ekonomi. Program ini terbukti efektif dalam meningkatkan pengetahuan, keterampilan, dan semangat kemandirian petani. Implementasi sistem pertanian terintegrasi berbasis sumber daya lokal memiliki kontribusi strategis dalam mendukung ketahanan pangan dan pemberdayaan ekonomi masyarakat pedesaan.

Abstract

Air pollution is an environmental issue that has a broad impact on human health and ecosystem balance. PT PLN Nusantara Power UP Nagan Raya as a coal-fired steam power plant (PLTU) has the potential to produce exhaust emissions that can reduce air quality in the surrounding area. This study aims to assess the impact of exhaust emissions on ambient air quality in organizations around the PLTU. The study uses a quantitative descriptive approach by measuring several air pollutant parameters, namely SO₂, NO₂, CO, O₃, NMHC, PM₁₀, PM₂.₅, and Pb at the UA-1 observation point located east of the PLN Nusantara Power, then compared with ambient air quality standards based on PP No. 22 of 2021. The measurement results show that all pollutant parameters are still below the national air quality standard threshold, including SO₂ <33.438 μg/m³, NO₂ <6.143 μg/m³, CO 2298.91 μg/m³, PM₁₀ 22.80 μg/m³, and PM₂.₅ 16.11 μg/m³. This indicates that at the time of the measurement, coal burning activities at the PLN Nusantara Power had not had a significant impact on air quality in surrounding organizations. However, continuous monitoring is still needed to ensure air quality remains safe and prevent potential long-term health risks.

Abstract

Problem solving skills (PSS) are one of the high-level thinking skills that must be possessed by students. This skill will help students apply scientific content to solve problems in real life. The purpose of this study was to determine the effect of problem based learning (PBL) models with a radical construktivism module on PSS. Data were collected in February to March 2022. The method in this study used an experimental method with nonrandomized post test only control-group design. This research was conducted in two classes: the experimental class using PBL model learning with radical constructivism module and the control class that only using PBL model learning. The samples were 160 students. The instrument was tests to assess PSS. Data analysis used independent sample t-test to determine effect of PBL model learning with radical constructivism module on PSS. T-test results showed that value sig 0,05. The result showed that students who received PBL model learning and the radical constructivism module obtained significantly better PSS compared to students who only received PBL model learning

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pembelajaran modul interaktif digital berbasis PBL terhadap keterampilan pemecahan masalah peserta didik. metode penelitian menggunakan desain eksperimental pre-test post-test control group. Sampel penelitian sebanyak 80 peserta didik yang terdiri dari kelas eksperimen sebanyak 40 peserta didik dan kelas kontrol sebanyak 40 peserta didik, kelas eksperimen akan diberikan pembelajaran modul interaktif berbasis PBL sedangkan kelas kontrol hanya dengan pembelajaran PBL saja. Penelitian dilaksanakan di SMPN 1 Aceh Barat pada semester ganjil tahun ajaran 2023/2024. Instrumen tes yang digunakan adalah tes uraian keterampilan pemecahan masalah sebanyak 10 soal, penskoran data keterampilan pemecahan masalah berdasarkan panduan rubrik penilaian, dihitung rata-rata dan persentase kategori skor. Selanjutnya dianalisis menggunakan uji independent sample t-test untuk melihat pengaruh perlakuan terhadap keterampilan pemecahan masalah peserta didik. Hasil analisis diperoleh t hitung > t tabel (3,124 >1,990), bahwa penerapan modul interaktif digital berbasis PBL berpengaruh terhadap keterampilan pemecahan masalah peserta didik.
