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%.

Abstract

Penelitian ini bertujuan mempelajari pengaruh perkembangan ekonomi terhadap volume sampah di Kota Salatiga dengan menggunakan tiga indikator perkembangan ekonomi, yaitu pertumbuhan ekonomi tahunan, PDRB riil dan PDRB rill per kapita. Hasil penelitian ini menemukan pengaruh positif PDRB riil dan PDRB riil per kapita tidak signifikan, tetapi pertumbuhan ekonomi berpengaruh signifikan positif terhadap volume sampah. Karena aktivitas ekonomi selalu diharapkan mengalami pertumbuhan dan jumlah penduduk yang merupakan produsen sampah juga selalu bertumbuh, maka satu-satunya cara untuk meredam volume sampah adalah melalui penerapan teknologi ramah lingkungan. Hal itu harus dilakukan bukan hanya melalui gerakan untuk mengurangi atau mendaur ulang sampah plastik, tetapi juga melalui pengelolaan sampah. Pemerintah salatiga harus berani merancang kebijakan untuk mengubah perilaku masyarakat melalui kebijakan yang bersifat insentif maupun disinsentif.
