Abstract

Permasalahan  yang  dihadapi  dalam upaya peningkatkan produksi  kedelai saat ini adalah kurangnya daya dukung lahan yang produktif. Hal ini disebabkan terjadinya  degradasi serta kerusakan lahan akibat pola pertanian konvensional saat ini yang lebih mengutamakan penggunaan input tinggi seperti pupuk an-organik dan pestisida. Oleh karena itu, peningkatan produktivitas dan kualitas kedelai harus diupayakan dengan cara-cara yang lebih baik, seperti menggunakan pupuk organik. Sumber pupuk organik dapat berasal dari berbagai biomas  atau bahan organik, seperti sisa tanaman atau hewan. Setiap bahan organik memiliki kandungan atau komposisi unsur hara yang berbeda-beda. Tujuan dari penelitian ini adalah mengetahui pengaruh penggunaan pupuk organik terhadap pertumbuhan dan hasil kedelai. Penelitian ini merupakan percobaan faktorial dalam rancangan acak kelompok, dengan 2 faktordan 12 perlakuan. Jika terdapat perbedaan nilai tengah dilakukan dengan menggunakan Uji Nyata Jujur (BNJ) pada taraf 5 % dan 1 %. Hasil penelitian menunjukkkan bahwa  perlakuan pupuk organik, serta interaksi antara pupuk organik dan varietas tidak menunjukkan perbedaan yang nyata terhadap jumlah polong isi, jumlah polong hampa, berat polong isi dan berat biji pertanaman. Sedangkan perlakukan varietas menunjukkan perbedaan yang nyata terhadap jumlah polong isi, jumlah polong hampa, berat polong isi dan berat biji pertanaman. Varietas Detam memberikan jumlah polong isi, jumlah polong hampa, berat polong isi dan berat biji pertanaman lebih tinggi dibandingkan dengan varietas Anjasmoro dan Edamami. Kata kunci : kedelai, pupuk,  organik.

Abstract

Red ginger is one of the herb plants that is widely used throughout the world, it can be used as spices, seasonings, raw materials for the traditional medicine industry, Phyto-pharmacy, healthy food and drinks, and also cosmetic and body care products. From 2014—2018 ginger production in Indonesia fluctuated with a growth rate of -36.36% 2018. The application of growth regulators in ginger cultivation can be an alternative to encouraging increased productivity and improving ginger quality. This research aimed to investigate the growth response of red ginger in various concentrations of growth regulator (paclobutrazol) and to obtain the optimum concentration of growth regulator (paclobutrazol) on stimulating red ginger growth. This research was conducted in Politeknik Negeri Lampung, from June to October 2020. Treatments were single-arranged in a completely randomized block design with three replications, each replication consisted of two samples, and each sample consisted of two subsamples. The treatments tested were five levels of paclobutrazol as a growth regulator (0 ml.l-1, 2 ml.l-1, 4 ml.l-1, 6 ml.l-1, and 8 ml.l-1). The result of this research showed that the best growth response of red ginger was obtained on the application of 4 ml.l-1 paclobutrazol. Keywords: red ginger, paclobutrazol, polynomial orthogonal

Abstract

One of the essential factors in edamame soybeans production is the use of quality soybean seed. Quality seeds had high viability and vigor values. One of the problems faced in the supply of quality seeds is seed deterioration. Seed deterioration is a process of decreasing seed vigor and viability during storage. Priming is a seed invigoration technique which is a process that controls the hydration-dehydration of seeds for metabolic processes to take place before germination. This objective was to determine the effect of priming media on the viability and vigor of edamame soybean seeds. This study was carried out from November 2021 to January 2022  in the Seed Technology Study Program greenhouse, Politeknik Negeri Lampung. This study used a factorial Completely Randomized Design (CRD) consisting of two treatment factors. The first factor consisted of four soaking media, specifically K1 = Aquadest, K2 = 〖GA〗_3, K3 = coconut water, and K4 = Atonik. The second factor is soaking time (L), which consists of L1 = 4 hours, L2 = 8 hours, and L3 = 12 hours. The observed variables in this study were germination, vigor index, maximum growth potential, growth simultaneity, growth speed, and root length. The interaction between priming treatment and soaking time had a very significant effect on the germination rate (DB), maximum growth potential (PTM), and growth simultaneity (KST). Meanwhile, the growth speed (KCT), vigor index (IV), and root length (PA) had no significant effect. The best invigoration priming treatment is coconut water as a medium with a soaking time of 12 hours which has the highest value.
