“…While, the Rootone-F application at BP 936 significantly reduce the shoots number and leaf length. This result is different from the other research on Robusta coffee, Rootone-F 100-150 ppm increased root length and growth index [21,22]. Giving Rootone-F 100 ppm to Manglid plant resulted in the average shoots number (5), root length (8.85 cm), and average root number (6.75) and was significantly different from other treatments [23].…”

Liberica, Robusta and Excelsa coffee are cross-pollinated so that their vegetative propagation uses cuttings. Plant growth regulators (PGR) such as Rootone-F could accelerate root growth on cuttings. The study aimed to determine the effect of Rootone-F concentration on the growth of one segment cuttings. The study was conducted at the Indonesian Industrial and Beverage Crops Research Institute (IIBCRI) from January to March 2020. The research design was a factorial, Completely Randomized Design, with three replications. The first factor was coffee species, i.e., Robusta (BP 936), Liberica (LIM 1 and LIM 2), and Excelsa, and the second factor was Rootone-F concentrations were 0, 100, 200, 300, 400, and 500 ppm. The characters observed were callus diameter, leaves number, shoots number, and leaf length. The results showed there was an interaction between coffee species and Rootone-F concentration on shoots number and leaf length. Every factor affected callus diameter and leaves number, respectively. Application without Rootone-F (0 ppm) gave a higher value of callus diameter and leaves number of LIM 1. Rootone-F concentration that could increase the shoots number and leaf length was 500 ppm for Lim 1, 400 ppm for Lim 2, 0 ppm for BP 936, and 100 ppm for Excelsa.

“…Untuk mendapatkan tanaman unggul kopi robusta dapat diperoleh dengan dua cara, yaitu dengan cara menggunakan biji (generatif) dan vegetatif salah satunya setek. Metode perbanyakan secara generatif untuk kopi robusta ini sering tidak seragam karena mengalami pemisahan sifat-sifat (segregasi), baik dalam pertumbuhannya dan produktivitasnya karena kopi robusta ini memiliki sifat tidak cocok dalam penyerbukan sendiri yang dipengaruhi oleh gen tunggal dengan banyak alel yang mengakibatkan variasi sangat tinggi dari induknya jika biji tersebut digunakan (Simatupang et al, 2018). Selain itu, Pradipta (2018) menyatakan bahwa perbanyakan vegetatif memberikan produksi bobot kopi kering lebih tinggi (1,585 kg) dibandingkan dengan tanaman hasil perbanyakan generatif (0,231 kg).…”

“…Maka dari itu dalam mendukung pertumbuhan setek kopi perlu diketahui jumlah ruas yang tepat. Selain itu, menurut Simatupang et al (2018), jenis bahan setek yang berbeda memiliki pengaruh pada persentase hidup dan tumbuh untuk setek daun tanaman kopi robusta.…”

Coffee is one of the commodities in Indonesia that excels in exports, and one of the most widely cultivated coffees in Indonesia is robusta coffee. Propagation by segment cuttings on Robusta coffee plants can produce new plants in large numbers and have the same gene characteristics as the parent in a short period. Then there is a growth regulatory administered exogenously (from outside) are an alternative way to accelerate root formation in plants. This study was conducted to determine the effect of the number of segments and concentration of Rootone-F on the growth of robusta coffee cuttings. The research was conducted for three months, from 23 March 2021 to 15 June 2021. The research was conducted at the Kaliwining Gardens, the Coffee and Cocoa Research Center, Jember. The statistical method used was a completely randomized design (CRD) by factorial. The first factor was the number of segments and the second factor was the concentration of Rootone-F; there were 12 treatment combinations and three replications. The results showed that the number of internodes' treatments was significantly different on shoot length, root wet weight, and root dry weight. The concentration of Rootone F was not significantly different for all variables observed.

Coffee is one of the leading plantation commodities in the world trade area. The utilization of plant waste in the form of water shoots from BP308 robusta coffee is a new innovation in anticipating global environmental changes. The research aims to support seed availability by utilizing wastewater shoots as seed candidates in anticipation of global environmental changes that can provide added value and income for farmers. The research was conducted in the District of Pupuan, Tabanan, Bali. The implementation period is 2 years (2018-2020). This study was designed using a paired experimental design in the form of existing technological innovations and new seed innovations. Data were analyzed using the t test. The results showed that the seeds of existing technological innovations and new innovations were significantly different and not significantly different. Coffee leaf rust disease showed no significant differences in attack rates. Wet weight, total seed weight and shoot oven dry weight were higher in the new innovations respectively 42.14; 51.99 and 40.59%. The added value obtained from wastewater shoots is IDR 10,500.00 per tree. Conversion of added value for each farmer with ownership of 0.3–0.8 hectares (population 300-800) of trees generates an added value of IDR 3,150,000.00 to IDR 8,400,000.00 per year per farmer.
