Abstract

Persilangan varietas introduksi Purple Queen dan varietas lokal Surakarta (Mantili, Gilik ijo, dan Gogo kuning) dilakukan untuk pembentukan populasi dasar buncis polong Ungu. Buncis polong ungu merupakan salah satu hasil dari perbaikan sifat daya hasil tinggi dan memiliki kandungan anthosianin. Anthosianin adalah salah satu pigmen yang terekspresi sebagai karakter warna merah, biru, ungu pada bagian tanaman. Anthosianin pada tanaman berfungsi sebagai antioksidan. Seleksi generasi F5 menghasilkan tiga galur buncis terpilih yang telah menunjukkan penampilan yang seragam dan memiliki daya hasil tinggi sehingga pengujian daya hasil dapat dilakukan pada generasi selanjutnya. Tiga galur tersebut antara lain GIxPQ-35-11-23, GIxPQ-12-2-18 dan PQxGK-1-12-29. Pada generasi selanjutnya diperlukan pengujian daya adaptasi pada beberapa dataran antara lain adalah dataran rendah, tinggi, dan medium. Tujuan dari penelitian ini untuk mengetahui daya hasil galur buncis polong ungu generasi F6 yang ditanam pada dataran rendah. Penelitian ini dilaksanakan di Desa Jatikerto, Kecamatan Kromengan, Kabupaten Malang dengan ketinggian ±330 m dpl pada bulan Januari hingga Mei 2016. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan empat ulangan. Data dianalisis menggunakan analisis ragam (ANOVA), apabila terdapat pengaruh yang nyata dilanjutkan menggunakan uji lanjut Beda Nyata Jujur (BNJ) pada taraf 5%. Hasil menunjukkan bahwa galur GIxPQ-35-11-23 dan GIxPQ-12-2-18 memiliki potensi hasil sama dengan varietas pembanding Lebat 3. Karakter kualitatif ketiga galur F6 menunjukkan hasil yang seragam pada semua parameter yang diamati.

Abstract

The problem that arises during tissue culture learning is the limited laboratory facilities. The imbalance between the amount of equipment and the number of students causes the practicum to be carried out in turns for a long time, and is less efficient. The impact is that most students, after being assessed, obtain scores that are not as expected. Due to these problems, efforts are needed to utilize multimedia in virtual laboratories. This study aims to develop a virtual tissue culture laboratory at the Agribusiness Plant and Horticulture Vocational School and analyze the feasibility and effectiveness of the virtual tissue culture laboratory at the Agribusiness Plant and Horticulture Vocational School. This study uses the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The experimental method used is a one-group pre-test-post-test design, with the selected sample being the XI ATPH class, which has 36 students in the experimental class and 36 students as instrument testing subjects. The results showed that the virtual laboratory was categorized as feasible for tissue culture learning based on assessments by media and material experts. The virtual laboratory was also considered very practical for tissue culture learning. Based on the N-Gain Score calculation, the virtual laboratory improved tissue culture learning outcomes with a high category. This study concludes that the virtual laboratory can overcome the problem of limited practical facilities.
