Abstract

Microgreens have emerged as a new trend in urban farming due to more practice, efficiency, affordable, short periods of cultivation, and highly nutrition than other types of urban farming methods. The increase of physical development in Pandeyan, ??Yogyakarta due to the increase in population has caused a decrease in the area for plant cultivation. One of the solutions to overcome this problem is through the socialization of household-scale microgreens cultivation. Therefore, this socialization aimed to enhance the knowledge of the Pandeyan community regarding the definition of microgreens, types of plants that can be cultivated, benefits, stages of cultivation, and business opportunities. The socialization was delivered in the form of a webinar on Tuesday, 30th November 2021 using Zoom platform, with a total 32 of participants. This activity is divided into 3 stages: introduction, transfer of knowledge, and discussion. Based on the evaluation, this activity has succeeded in increasing the community's knowledge about microgreens, their benefits, and the stages of microgreens cultivation based on the high enthusiasm of the community during the discussion session.

Abstract

Browning of explants is a common problem in Kepel (Stelechocarpus burahol (Blume) Hook.f. & Thomson) in vitro culture, resulting in low explant in vitro regeneration of Kepel. Using nodal explant, the effect of explant immersion in ascorbic acid, the addition of ascorbic acid to the media, and dark and light incubation conditions were investigated. The browning prevention method was selected based on the delayed browning appearance time, the lowest broning intensity, and the highest percentage of callus. This present study used a completely randomized design with treatment variations: immersion explant in ascorbic acid 100 mg/L, addition of ascorbic acid 100 and 200 mg/L to the media, addition of ascorbic acid 100 and 200 mg/L and activated charcoal 1 g/L to the media, and incubation in dark and light conditions for 28 days. The results showed that the combination of the addition of ascorbic acid 200 mg/L to MS media and incubation in dark conditions were effective browning prevention methods in inhibiting browning appearance time (5 DAP), significantly reducing browning intensity (0.3), and increasing callus growth (100%) of kepel node explants during 28 days of culture. The results of this study are useful in establishing protocols for in vitro culture of Kepel plants, especially at the initiation stage, and can be expected to support the successful conservation of Kepel plants through in vitro propagation. Keywords: Ascorbic acid, Activated Charcoal, Browning, In Vitro Culture, Stelechocarpus burahol

Abstract

Kultur jaringan tumbuhan merupakan bagian dari topik bioteknologi yang dipelajari siswa SMA pada mata pelajaran Biologi di Sekolah Menengah Atas. Meskipun demikian, dalam prosesnya siswa mengalami kesulitan dalam pembelajaran bioteknologi terutama kultur jaringan tumbuhan karena pembelajaran berfokus pada pemberian teori tanpa dilengkapi dengan kegiatan praktikum. Selain itu, fasilitas laboratorium yang belum memadai menjadi faktor pembatas bagi pelaksanaan praktikum ini. Kesulitan dalam pembelajaran kultur jaringan tumbuhan ini juga dialami oleh siswa kelas X di SMA Stella Duce 2 Yogyakarta. Dalam upaya mendukung capaian pembelajaran topik Bioteknologi di kelas X dan mengatasi kesulitan dalam proses pembelajaran, maka kegiatan pengabdian dalam bentuk edukasi perlu dilakukan. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan melalui pengalaman praktikum pada topik kultur jaringan tumbuhan. Tahap pelaksanaan kegiatan meliputi tahap persiapan, pelaksanaan kegiatan (pemberian materi dan demonstrasi) dan tahap evaluasi. Hasil yang diperoleh selama kegiatan berlangsung adalah siswa terlibat secara aktif dalam proses diskusi dan tanya jawab, sebagian besar siswa dapat menjawab pertanyaan selama diskusi dan semua siswa berpartisipasi aktif dalam kegiatan praktikum serta mampu menyelesaikan kegiatan praktikum sesuai waktu yang diberikan. Berdasarkan hasil pelaksanaan tersebut, dapat disimpulkan bahwa kegiatan pengabdian berupa edukasi ini dapat membantu siswa dalam meningkatkan pengetahuan dan keterampilan dalam pembelajaran kultur jaringan tumbuhan.
