Kendala yang terjadi pada saat mengajar yaitu kurangnya media untuk diperlihatkan ke siswa tentang materi sel dan kurangnya sumber daya dalam pemanfaatan fasilitas yang tersedia di MA Pondok Quran di era pandemi seperti sekarang. Penelitian ini bertujuan untuk mengembangkan desain media, mengetahui kelayakan dan respon siswa terhadap media pembelajaran interaktif berbasis Articulate Storyline pada materi sel. Rancangan penelitian menggunakan metode Research and Development (RD) dengan model penelitian 4D dimodifikasi menjadi 3D yang dikembangkan oleh Sivasailam Thiagarajan, Dorothy S. Semmel dan Melvyn I. Semmel. Sumber data pada penelitian ini adalah validator yaitu ahli media dan ahli materi, guru bidang mata pelajaran biologi dan siswa kelas XI IPA MA Pondok Quran. Instrumen pengumpulan data menggunakan lembar validasi ahli media, lembar validasi ahli materi dan angket respon siswa. Teknik pengumpulan data menggunakan validasi ahli media, validasi ahli materi dan angket. Teknik analisis data menggunakan uji kelayakan dan respon siswa terhadap media pembelajaran interaktif berbasis Articulate Storyline. Hasil penelitian menunjukkan bahwa penelitian pengembangan ini menghasilkan media pembelajaran interaktif berbasis Articulate Storyline dengan link akses https://bit.ly/MediaInteraktifSelXI. Uji kelayakan media pembelajaran interaktif berbasis Articulate Storyline pada materi sel diperoleh hasil 85,28%. Respon siswa terhadap media pembelajaran mendapat hasil 83,6% dengan kriteria sangat positif. Hal ini dapat disimpulkan bahwa media pembelajaran interaktif berbasis Articulate Storyline sangat layak digunakan sebagai media belajar yang efektif untuk siswa kelas XI MIPA MA Pondok Quran.
Environmental characteristics can influence the distribu-tion of animal communities including fish in aquatic habitats such as a river. The study of fish communities in Cisadea River aimed to learn the relation between the fish community structure and the environmental characteristics of the river itself. This research was conducted in Cisadea River, Cianjur Regency, West Java, Indone-sia during dry season from July 2012 until February 2013. Samples of fish were caught using active fishing gear (Electrofishing Gear, spreading nets, scoop, lift net) and passive fishing gear (trap). The results showed that the quality of the physical chemistry of Cisadea waters was still in the normal range that could support fish life. The fish community in Cisadea River consisted of 11 orders, 26 families, 35 genera and 48 species. During the study, Rhyacichthys aspro (19,85%) and Glyptothorax plathypogon (20,15%) were the domi-nant species caught. The diversity index value (H’) was 2.87 (mid-dle category) with the dominance value of 0.09 (low category) and evenness value of 0.74 (high category). Moreover, community simi-larities according to the presence of species made the LC1 and LC2 locations in one group while the LC3 locations in a separate group.
Snakehead fish (Channa striata) is a freshwater fish with high economic value both as ornamental and consumed fish. However, the ability to adapt to fluctuating environmental states prompts snakehead fish to be susceptible to parasites, ectoparasites, and endoparasites. Gills, skin, and fins are the major body parts that are often infected with ectoparasites. This study aims to discover the macro pathology in gills, skin, and fins of ectoparasites-infected snakehead fish and its histopathology. This study was conducted from April to June 2021. Observational data on macro pathology and histopathology were analyzed qualitatively. The results indicated that the macro pathology of the skin, gills, and fins of snakehead fish infected with ectoparasites indicates discoloration, excess mucus production, the dull coloration of the gills, and irritation of the gills body surfaces, and skin hemorrhages. In conclusion, infection of ectoparasites affects several alterations in the skin, gills, and fins, both macro pathological and histopathological.
Based on the preliminary analysis, one of the things needed in learning is a learning media that describes the material clearly, briefly, easily understood, and fulfills offline and online learning. This research aims to develop a digital comic learning media on the concept of the human excretory system. This study uses the R&D (Research and Development) method with the ADDIE model. The instruments in this study include a validation questionnaire, practicality test sheets, readability questionnaire, and student response questionnaire sheets to the developed digital comic learning media. The research data were analyzed quantitatively by calculating the percentage. The results showed that the digital comics learning media was valid and feasible to be used as learning media (combined average of 83%). The results of the student response test showed a very good response to the digital comic learning media with a percentage of 84%
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.
