Abstract

Ubi jalar (Ipomoea batatas L.) ungu memiliki kandungan antosianin yang tinggi dibandingkan dengan jenis ubi jalar warna lainnya, yaitu sebesar 110,51 mg100 g-1. Salah satu varietas ubi jalar ungu yaitu Ayamurasaki, varietas ini memiliki umur panen 4—7 bulan. Penelitian ini bertujuan untuk menyeleksi klon ubi jalar ungu (berantosianin) dan memiliki bobot ≥ 250 g. tanaman-1 dari hasil persilangan bebas induk Ayamurasaki dengan seleksi tanam gulud tunggal. Penelitian ini dilakukan di lahan praktikum Politeknik Negeri Lampung yang terletak di Desa Hajimena Kecamatan Natar Kabupaten Lampung Selatan. Percobaan dilaksanakan pada bulan Oktober 2017 sampai dengan Januari 2018 dengan mengunakan metode seleksi tanaman tunggal dan dideskripsikan. Klon terpilih dari seleksi individu ditanam dalam 1 baris sebagai tanam tunggal. Pengamatan dilakukan mulai pada umur 21 hst dan diamati fenotipenya pada 2 tanaman setiap barisnya. Data pengamatan yang diambil yaitu data kualitatif dan kuantitatif. Hasil penelitian ini menunjukan bahwa (1) Klon ubi jalar yang memiliki antosianin (ungu) yaitu pada klon A2, A3, A4, A5, A7, A11, A12, A14 (2) Klon ubi jalar yang memiliki bobot umbi besar ≥ 250 g.tanaman-1 yaitu A2, A4, A5, A8, A11 dan A15 (3) Klon ubi jalar yang berwarna ungu memiliki bobot umbi besar ≥ 250 g.tanaman-1 dengan umur panen 3,5 bulan (genjah) yaitu A2, A4, A5, dan A11.

Abstract

Soybeans are a source of plant-based protein and a staple food ingredient, especially in Indonesia. Whenstored for extended periods, soybean seeds may experience quality deterioration, which can impact their productivity. Aneffort to improve the quality of deteriorated soybean seeds is through bio-invigoration treatment. The goal of bioinvigoration is to enhance seed metabolism through imbibition. One method that can be used as bio-invigorationtreatment is the application of plant growth-promoting rhizobium (PGPR). This research was conducted from May toJuly 2024 at the Seed Analysis Laboratory, Politeknik Negeri Lampung. The research was arranged in a CompletelyRandomized Design (CRD) with two factors, namely concentration (K) and soaking duration (L). For the concentrationfactor, there were four levels: 0% (K0), 6% (K1), 12% (K2), and 24% (K3), and the soaking duration factor consisted oftwo levels: 3 hours (L1) and 6 hours (L2). The factors were combined and repeated four (4) times, resulting in 32experimental units. Data were analyzed using variance analysis at 5% and 1% significance levels, and if significantdifferences were observed, further testing was conducted using the Least Significant Difference (LSD) test at the 5%level. The results showed that PGPR can improve the viability and vigor of Detap-1 soybean seeds that have experienceddeterioration. Treatment with 12% PGPR with a 6-hour soaking duration can increase the seed's germination byapproximately 11.33%, from the initial germination rate of 68% to 80%.
