Abstract

This research aims to determine the effect of from kepok banana peel extract (Musa acuminata balbisiana Colla) and BAP and their interaction on the growth of red potato plantlets (Solanum tuberosum L.) in vitro. This research was conducted in September-October 2023 at the G10 Agrotech Medan Plant Tissue Culture Laboratory Jl. Sei Bahorok No. 47 F Medan Baru. This research used a factorial Completely Randomized Design (CRD) with two factors. The first factor is the concentration of Kepok banana peel extract in 3 levels, namely (0, 25 and 50 g/L) and the second factor is BAP which consists of 4 levels, namely (0, 0.5, 1 and 1.5 mg/L). 12 treatment combinations were obtained and each treatment was repeated 3 times to obtain 36 experimental units. The research parameters were plantlet height, number of shoots, number of leaves and number of roots analyzed using Analysis of Variance (ANOVA) and if they were significantly different, further tests would be carried out using the Duncan Multiple Range Test (DMRT) at the 5% level. The results showed that the treatment of kepok banana peel extract and BAP had a significant effect on plantlet height, number of shoots, number of leaves and number of roots. The highest average plantlet height was produced by banana peel extract 50gr/L (7.60 cm), BAP 1mg/L (6.70 cm). The highest number of shoots was produced by banana peel extract 50gr/L (6.33 shoots), BAP 1.5 mg/L (6.33 shoots). The highest number of leaves was produced by sweet corn extract 25 gr/L, namely (10.00 leaves), BAP 0.5 mg/L as much as (8.00 leaves). The highest number of roots was produced by the 50gr/L sweet corn extract treatment, namely (12.00 roots), the highest number of roots was produced by BAP 1 mg/L, namely (7.33 roots). The highest average plantlet height, number of shoots and leaves were produced by the A2B1 treatment interaction, namely 7.40 cm plantlet height, 6.33 shoots and 16.33 leaves. The highest number of roots was produced by the A2B2 treatment interaction, namely 8.67 roots.  This is an open-access article under the CC-BY-SA license

The results showed that all participants responded positively to the socialization activities, with 58.3% strongly agreeing and 41.7% agreeing on its benefits. Additionally, the post-test results showed an enhancement in material comprehension, where 63.6% of participants were categorized as excellent, 32.7% as good, and only 3.6% as fair. Thus, the socialization of bullying prevention education has proven to be effective in strengthening participants' awareness and understanding of the impact and strategies of bullying prevention. This program could serve as a preventive intervention model in schools and universities and was recommended for continuous implementation to strengthen an educational culture free from bullying.

Abstract

Minimnya kegiatan praktikum dan kurang lengkapnya materi pada buku kultur jaringan di perpustakaan serta tidak terintegrasikannya model pembelajaran yang dapat melatih keterampilan proses sains (KPS) di dalam buku-buku tersebut membuat rata-rata tingkat KPS mahasiswa Biologi di Universitas Negeri Medan tergolong sedang (49,26). Penelitian ini bertujuan untuk mengembangkan buku ajar kultur jaringan berbasis Project Based Learning serta mengetahui tingkat keefektifan buku dalam meningkatkan KPS mahasiswa biologi pada materi kultur jaringan. Penelitian menggunakan model pengembangan 4D. Subjek penelitian ini terdiri dari ahli materi, ahli media dan desain, dosen kultur jaringan dan 47 orang mahasiswa. Instrumen yang digunakan: lembar studi dokumentasi, lembar wawancara, lembar angket analisis kebutuhan, lembar uji validasi, angket respon dosen dan mahasiswa serta tes KPS. Teknik pengumpulan data yang menggunakan studi dokumentasi, wawancara, kuesioner dan tes sedangkan teknik analisis data dilakukan dengan uji N-Gain. Hasil menunjukkan bahwa persentase kelayakan buku berdasarkan penilaian ahli materi 90,26% (sangat layak) dan ahli media desain 98,6% (sangat layak). Respon dosen memperoleh persentase sebesar 89,06% dengan kategori layak. Uji coba perorangan sebesar 91,66%, uji coba kelompok kecil sebesar 89,5% dan uji coba kelompok besar sebesar 90,21%. Ketiganya berada pada kategori sangat layak. Rata-rata N-Gain KPS mahasiswa memperoleh nilai 0,6 dan rata-rata N-Gain KPS per indikator memperoleh nilai 0,65, kedua angka tersebut berada pada kategori sedang. Berdasarkan hasil penelitian tersebut, dapat disimpulkan bahwa  buku ajar berbasis PjBl cukup efektif dalam meningkatkan KPS biologi pada materi kultur jaringan di Universitas Negeri Medan.
