Abstract

Penelitian ini bertujuan untuk mengidentifikasi dan membandingkan kualitas kompos organik yang menggunakan EM4 (Effective Microorganism) dan kompos yang menggunakan MOL (mikroorganisme lokal) yang terbuat dari keong mas. Penelitian dilaksanakan selama bulan Maret-Juli 2020 di laboratorium Jurusan Biologi Fakultas MIPA Universitas Negeri Gorontalo; pengujian lebih lanjut dilakukan di laboratorium PT. hal. Tolangohula, Gorontalo. Parameter penelitian meliputi kualitas fisik kompos (suhu, kadar pH, kelembaban, susut bobot, warna, bau, dan tekstur) dan kualitas kimia (kadar air, kadar C organik, kadar N, dan rasio C/N). . Metode deskriptif digunakan untuk menganalisis data. Hasil penelitian menunjukkan bahwa kualitas fisik kompos yang menggunakan bioaktivator EM4 telah mencapai spesifikasi kompos matang sebagaimana diatur dalam SNI No. 19-7030-2004. Sedangkan kompos yang menggunakan MOL dari keong emas menghasilkan sedikit bau yang tidak sedap. Selain itu, dari segi kualitas kimia, kualitas kompos yang menggunakan EM4 lebih mendekati spesifikasi kompos matang dibandingkan dengan kompos MOL.

Abstract

This study aims to describe student learning difficulties in inheritance material in class XII SMA Negeri 1 Tapa. This type of research is descriptive quantitative. Data collection techniques used teacher activity sheets, student activity sheets, learning outcomes tests, questionnaires and interviews. The results of the study found: The results of learning implementation at meetings 1 and 2 with a value of 82, 81%, with a good category, at meetings 3 and 4 with a value of 78, 78 with a sufficient category. The results of student activity at meetings 1 to meeting 4 with a value of 54, 17, 51.17, 51.69, 53.39% with a less category. The results of student responses with aspects of physiology and psychology with a value of 69.58, 60.24% with a sufficient category and aspects of sociology with a value of 55.47% with a very sufficient percentage. The results of the analysis of learning outcomes tests with a value of 96% incomplete. In conclusion, there are many students who experience learning difficulties in terms of physiological, psychological, and sociological aspects.
