“…Soaking at higher temperatures (more than 50 0 C) will only damage the germination process of Arabica coffee seeds; the same also applies to sprout length and vigor index. In other words, soaking in water at a temperature of more than 50 0 C decreases the viability of Arabica coffee seeds (Suhendra et al, 2020) 50 0 C for 30 minutes showed a significantly different value on germination percentage, sprout length, and vigor index, yet the difference between the two treatments on the three germination parameters was not big enough. Soaking of seeds at high temperatures is often done to get uniform and simultaneous sprouting (Botumile et al, 2020).…”

It takes three weeks to analyze the germination percentage of Arabica coffee seeds germinated using paper and a three-day water-soaking method. This 3- week period is considered too long for seed distribution to remote areas. Thus, we need to modify this germination test needs to be modified to have a shorter test time. Temperature treatment is one method to break the seed dormancy period for faster germination. This study aimed to obtain a faster and more precise method of germination test on Arabica coffee seeds. This study employed a 3 x 4 factorial complete randomized block design with three replications in which Arabica coffee varieties of Gayo-1, Kartika-1, and Sigararutang as the first factor and the temperature of the soaking water of the seeds (25 0C, 50 0C, 75 0C, and 90 0C) as the second factor. The research was conducted at the Plant Breeding Laboratory, Indonesian Coffee and Cocoa Research Institute (ICCRI), for four months. Findings showed that the interaction between treatments was only found in seed germination percentage. Soaking in room temperature water (control) for three days was better than using water at 50 0C, 75 0C, and 90 0C on the germination percentage, sprout length, and vigor index. Observations of Arabica seed germination could be shortened to 14 days compared to the standard 21-day observation. During the seedling phase, the shoot growth and root growth of the Arabica coffee seeds soaked in water at 50 0C showed no significant difference from the control. Soaking at 75 0C and 90 0C damaged the embryo and resulted in rotten seeds. Different varieties led to different germination percentages, sprout lengths, and fresh weight of seedling shoots. The method of soaking at 50 0C for 30 minutes could be used as an alternative in germination test of Arabica coffee seeds because it showed small negative effect on germinated seed and seedling quality but it shorten thetesting time for three days.

Coffee is one of the plantation commodities that has an important role in the national economy, especially as a source of foreign exchange because it has high economic value. The productivity of arabica coffee (Coffea arabica L.) in Indonesia in the 2019/2020 period decreased by 2.7% with a total production of around 95 million sacks. This study aims to determine the effect of gibberellin (GA3) on the germination of the arabica coffee bean variety S795. The experimental design was a completely randomized design factorial consisting of two factors with four replications for each treatment. The first factor was the plant growth regulator gibberellin concentration which consisted of 100 ppm (K1), 200 ppm (K2), and 300 ppm (K3). The second factor is the soaking time which consists of 12 hours (P1) and 24 hours (P2). The result showed that the interaction between GA3 concentration and soaking time had no significant effect on all observed parameters (germination percentage, germination rate, seedling height) in the germination of arabica coffee bean variety S795. Based on the table of average interactions between GA3 concentration and soaking time, it can be concluded that the K1P1 treatment with 12 hours of soaking time at a concentration of 100 ppm was the best treatment for the parameters of germination percentage, seedling height, and root length. The K2P1 treatment with 12 hours of immersion time at a concentration of 200 ppm was the best treatment for the germination rate parameter, namely 36.34 days.

“…Hal ini berarti perendaman GA3 eksogen selama 18,16 jam pada tanaman mampu memberikan hasil yang optimum pada pertumbuhan vegetatif sehingga terjadi penambahan berat segar tanaman. Asam giberelat yang diberikan pada benih memberikan pengaruh yang besar pada perpanjangan ruas yang berhubungan dengan pertumbuhan sel-sel tanaman (Li et al 2020;Siregar 2017;Suhendra et al 2021). Berat segar ini dapat digambarkan pertumbuhan tanaman yang subur disebabkan oleh pembelahan sel yang meningkat.…”

Johar (Cassia seamea) is a medicinal plant with a cassiarin A compound to combat malaria and has a low Cassiarin A is an active compound in Johar (Cassia seamea) medicinal plant capable of combating malaria, despite showing a low seed production rate due to dormancy. This inactivity is severed using gibberellic acid (GA3) treatments. This study aims to determine the effects of concentration and soaking period of GA3 on seed germination and growth of Johar seedlings. A completely randomized design (CRD), consisting of 2 treatments was applied as the research method. The first treatment employed GA3 concentrations of 0, 45, 90 and 135 ppm, while the second was based on the soaking interval at 6, 12, 18 and 24 hours. The results showed the capacity of GA3 able to shatter the seed dormancy with percentage germination of 43.03% and a concentration of 50.28 ppm. Therefore, the interaction of the two treatments significantly influenced the growth of Johar seedlings. Consequently, the concentration of GA3 at 79.89 ppm increased the root length to 52.19 cm, while 84.68 ppm produced a total of 20.91 roots, after a 6 hour soaking. In addition, the 96.67 ppm expanded the stem diameter by 0.93 cm.
