Bakteri pendegradasi selulosa berperan dalam mendegradasi selulosa kompleks menjadi sederhana berupa glukosa menggunakan enzim selulase. Tujuan penelitian ini untuk mendeskripsikan karakteristik setiap isolat dan mendeskripsikan potensi bakteri dalam mendegradasi selulosa yang berhasil diisolasi menggunakan media CMC (Carboxy Methyl Celullose) dari tanah gambut di Desa Tagagiri Tama Jaya, Kecamatan Pelangiran, Kabupaten Inhil, Riau. Metode yang digunakan merupkan penelitian observasional. Bakteri dikarakterisasi dari tanah gambut menggunakan media CMC dengan metode pour plate method. Karakterisasi dilakukan secara morfologi dan fisiologi biokimia. Uji potensi berdasarkan indeks selulolitik (IS) yang dilihat dari zona bening dari hasil pewarnaan congo red 0,1%. Hasil isolasi diperoleh 24 bakteri pendegradasi selulosa. Sebanyak 10 isolat dengan IS tertinggi dikarakterisasi yaitu isolate SL5; SL7; dan SL15 dengan kategori rendah, SL17 kategori sedang, dan SL9; SL11; SL12; SL13; SL14; dan SL22. Sebanyak 6 anggota genus bakteri selulolitik yang ditemukan yaitu Neisseria (SL5; SL9; dan SL12), Micrococcus (SL7), Bacillus (SL11), Pseudomonas (SL13; SL14 dan SL17), Flavobacterium (Sl15), serta Actinobacillus (SL22).
Good teaching materials in learning need to include facts and phenomena. In addition, it provides opportunities for students to carry out research activities to practice creative thinking skills. The study aims to describe the validity of e-modules that can enhance students' creative thinking skills through utilizing the environment as a learning resource based on Riau's local wisdom to maintain the sustainability of the ecosystem through student research activities. This study uses a development model with research and development (R&D) methods which refer to the 4D development model. The research instrument used in this study is an e-module validation sheet for education expert lecturers and material expert lecturers to be analyzed quantitatively and qualitatively from the aspects of content feasibility, presentation feasibility, and linguistic feasibility. Based on the validation carried out, the average validity score of all aspects was 89,74% with very valid criteria. The validity score includes aspects of content feasibility of 90,71% with a very valid category, 89,17% presentation feasibility with a very valid category and linguistic feasibility of 89,35% with a very valid category. These results indicate that the developed e-module is suitable for use in learning biology on environmental pollution materials. Based on the student response questionnaire, the overall e-module eligibility category was 94%. The presentation feasibility aspect was 94,28%, language feasibility was 92%, and content feasibility was 93,34%, each with a very positive category. This means that e-modules that have been developed can support students to think creatively
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
