Abstract

Seaweed is widely used in many industries such as cosmetic foods, and drugs resulted in its increasing demand. To complete the market demand, it is necessary to escalate the seaweed cultivation. One of the problems of cultivation is the availability of the seed. The conventional and vegetative system of seaweed seed reproduction in the form of direct fragmentation or thallus cutting affects the degradation of seed quality. Therefore, another system of reproduction must be performed. One of the best ways to multiply the plants is tissue culture technique. Tissue culture is a plant multiplication technique using the artificial medium in a controlled and sterilized environmental condition. The advantage of this technique is the seeds will be all even, pathogen-free, numerous in one single production, and not influenced by any season. Some methods used in seaweed tissue culture are protoplasm culture, spore culture, and somatic embryogenesis. The government takes a serious action in seaweed industry by releasing the regulation of seaweed research and development through Presidential Regulation No. 33 of 2019 about the roadmap of National seaweed industry development 2018-2021. Therefore, the research and development of seaweed tissue culture is still widely open for its underexplored potential. On the other plants, this technique has reached the utilization stage to produce bioactive compounds e.g. the increasing production of saponin in Javanese ginseng callus culture. Based on that reason, the tissue culture technique can be implemented to search seaweed’s bioactive compound potential.

Abstract

Program studi pendidikan biologi Universitas Tidar telah memberlakukan pembelajaran daring mulai semester genap tahun akademik 2019/2020 sebagai upaya memastikan perkuliahan tetap berjalan di masa pandemi Covid-19. Penelitian ini bertujuan untuk menganalisis kendala yang dialami mahasiswa pendidikan biologi saat pembelajaran daring di masa pandemi Covid-19. Penelitian ini menggunakan metode penelitian survai deskriptif. Teknik pengumpulan data dalam penelitian ini menggunakan angket yang berisi 11 pertayaan yang dibagikan kepada mahasiswa pendidikan biologi angakatan 2018, 2019, dan 2020. Hasil penelitian ini menunjukkan beberapa kendala mahasiswa saat pembelajaran daring diantaranya yaitu: motivasi belajar yang menurun, lingkungan yang kurang mendukung, perangkat yang kurang memadahi, jaringan internet yang sulit, pemenuhan kebutuhan kuota, kesulitan memahami materi, kendala mengerjakan kuis, tugas maupun pengumpulannya. Prosentase responden yang mengalami kendala saat pembelajaran daring yaitu sebanyak 61,87%, sedangakan prosentase responden yang tidak mengalami kendala saat pembelajaran daring sebanyak 38,13%. Kendala yang dialami oleh para mahasiswa pendidikan biologi saat pembelajaran daring akan membuat pembelajaran daring menjadi tidak maksimal, sehingga penelitian ini diharapkan memiliki kontribusi sebagai evaluasi maupun acuan perbaikan pembelajaran agar pelaksanaan pembelajaran daring menjadi lebih baik kedepannya.Kata Kunci: Kendala, pembelajaran daring, pandemi Covid-19
