“…Kelembapan yang tersedia selama penelitian dapat mencegah stek kopi mengering. Puspita et al (2020), menyatakan bahwa tumbuh kembang tanaman dipengaruhi oleh faktor lingkungan seperti intensitas cahaya, suhu, dan kelembaban. Jika dapat mengelola lingkungan dengan benar maka akan mempercepat pertumbuhan dan perkembangan stek kopi.…”

Robusta coffee plants are cross-pollinated, so the genetic characteristics of the new plant are not the same as the parent if propagation is carried out generatively. One way to overcome this problem is through vegetative propagation. The research aims to determine the effectiveness of organic and inorganic growth regulators to support the growth of robusta coffee cuttings. This research was conducted at the Experimental Station, Campus II, Batanghari University in Pijoan, Jambi from April to August 2022. The research used a completely randomized environmental design. The treatment design is 5 levels of organic and inorganic growth regulators, namely (p0): control, (p1): 50% onion shallot extract, (p2): natrium nitrophenol 0.60 mLL-1, (p3): 75% onion shallot extract, (p4): natrium nitrophenol 0.90 mLL-1. The parameters observed were live cuttings, rooted cuttings, sprouted cuttings, rooted and sprouted cuttings, number of roots, dry weight of roots, air temperature and air humidity. Research data was processed using anova. Further data processing takes the form of orthogonal contrast to compare organic and inorganic growth regulators. A onion shallot extract concentration of 75% is better than a concentration of 50% and a natrium nitrophenol concentration of 0.9 mLL-1 is better than a concentration of 0.6 mLL-1. Treatment with 75% onion shallot extract resulted in 100% growing cuttings, 100% sprouting cuttings, 60.22% rooted cuttings, and 60.22% sprouting and rooting cuttings. Natrium nitrophenol treatment with a concentration of 0.9 mLL-1 resulted in 100% growing cuttings, 100% sprouting cuttings, 65.55% rooted cuttings, and 65.55% sprouting and rooting cuttings. Organic growth regulators from onion shallot extract and inorganic substances from natrium nitrophenol have the same effect in stimulating the growth of robusta coffee cuttings.

“…Fungsi hormon auksin dan sitokinin diantaranya untuk memicu pembelahan sel yang berimplikasi terhadap peningkatan pertumbuhan tumbuhan baik pucuk maupun akar, sedangkan hormon giberelin berfungsi untuk memecahkan dormansi biji. Pemecahan dormansi biji merupakan awal dari proses pembibitan [5]- [7].…”

The process of cayenne pepper seedling begins with soaking the seeds in liquid to break the dormancy of the seeds. The effect of soaking cayenne pepper seeds using PGPR solution obtained from the root system of cultivated plants, namely cayenne pepper (Capsicum frutescens L.), maize (Zea mays L.), peanuts (Arachys hypogaea L.), and rice (Oryza sativa L.) which had been harvested was the purpose of this study. Cayenne pepper seeds were soaked overnight using PGPR, then the seeds were sown in a planting medium mixed with soil, manure, compost and husk charcoal in a ratio of 2:1:1:1. Cayenne pepper seedling plantations were observed for 4 WAP. Using one-way ANOVA test for research data. Soaking cayenne pepper seeds using PGPR had a significant effect on seedling growth in terms of height, number of leaves, and stem diameter parameters with optimal treatment of 50% concentration. Meanwhile, PGPR immersion for seedling root length parameters did not have a significant effect.
