Abstract

This study aims to analyze learning difficulties in relation to students' levels of conceptual understanding—categorized as conceptually understood, misconceptions, and lack of understanding—among 11th-grade science students (Grade XI MIPA) in the Teupah Barat District, specifically concerning the topic of hydrocarbons. A Two-Tier Multiple Choice diagnostic test was employed as the primary instrument. The study utilized a qualitative descriptive method. The population comprised all Grade XI MIPA students from senior high schools in the Teupah Barat District. The sample included 40 students from SMA Negeri 1 Teupah Barat and SMA Negeri 2 Teupah Barat, selected using purposive sampling techniques. Data analysis was conducted using descriptive statistics to process and interpret the students' responses. The results indicate that the Two-Tier Multiple Choice diagnostic test was effective in identifying students' conceptual understanding and in uncovering alternative conceptions through dominant incorrect answer choices that diverged from scientifically accurate concepts.The findings reveal that among the participants, 64% demonstrated conceptual understanding, 23% exhibited misconceptions, and 13% showed a lack of understanding regarding the topic of hydrocarbons. These results highlight the diagnostic tool's utility in pinpointing areas where conceptual reinforcement is necessary to enhance students’ comprehension in chemistry education.

Abstract

Kegiatan pemberdayaan perempuan melalui pemanfaatan limbah organik menjadi Ecoenzyme telah dilaksanakan bersama LBK Keumalahayati di Desa Blang Cruem, Kecamatan Muara Dua, Kota Lhokseumawe. Program ini merupakan implementasi pengabdian berbasis potensi lokal yang bertujuan mengatasi permasalahan mitra terkait keterbatasan pengetahuan, keterampilan, dan rendahnya kesadaran ekologis dalam pengelolaan limbah rumah tangga. Aktivitas yang dilakukan meliputi Focus Group Discussion (FGD) persiapan, sosialisasi mengenai ecoenzyme dan ekonomi sirkular, workshop praktik pembuatan ecoenzyme, pendampingan fermentasi, serta evaluasi capaian kegiatan. Hasil evaluasi menunjukkan tingkat keberhasilan kegiatan berada pada kisaran 80–90% yakni tahap sosialisasi, 85% peserta memahami konsep ecoenzyme dan prinsip ekonomi sirkular; workshop mencapai 80% dengan penguasaan keterampilan teknis pembuatan; pendampingan fermentasi berhasil menghasilkan lebih dari 90 botol produk ecoenzyme; serta evaluasi menunjukkan peningkatan kesadaran ekologis dan motivasi kewirausahaan. Dapat disimpulkan bahwa program ini efektif meningkatkan pengetahuan, keterampilan, dan kesadaran ekonomi-sosial masyarakat, memperkuat kemandirian ekonomi keluarga, memberdayakan perempuan, serta mendukung pencapaian tujuan pembangunan berkelanjutan di tingkat komunitas.
