Abstract

Java ginseng (Talinum paniculatum Gaertn.) is a medicinal plant, the roots of which are commonly used in traditional medicine. In its natural habitat, the roots grow very slowly, requiring two to three years to produce 100 g of roots per plant. Plant tissue culture could therefore provide an alternative means of accelerating root growth. This research aimed to optimize root induction and determine the effect of phosphate (KH2PO4) concentration and the ratio between ammonium and nitrate (ammonium:nitrate) on the biomass of Java ginseng adventitious roots in in vitro culture. Stem and leaf were used as explants and various combinations and concentrations of IBA and BAP, kinetin, and TDZ were used as growth regulators. Leaf explants were grown in Murashige and Skoog (MS) media supplemented with IBA 2 mg/L and various concentrations of phosphate (170; 212.5; 255; 297.5; 340; 382.5; 425; 467.5; 510 mg/L) and various ammonium:nitrate ratios (21:19 mM as the control, 0:30 mM, 10:20 mM, 15:15 mM, 20:10 mM, 30:0 mM). Cultures were maintained for 6 weeks. The observed parameters were fresh weight, dry weight, the duration of root formation, and the number and length of adventitious roots. The data were analyzed using Analysis of Variance. The results showed that the concentration of phosphate and the ammonium:nitrate ratio significantly influenced the amount, length, fresh weight, and dry weight of Java ginseng adventitious root. The highest fresh weight (37.47 mg) and dry weight (5.53 mg) were achieved in the treatment of double phosphate concentration (KH2PO4 340 mg/L), while an ammonium:nitrate ratio of 10:20 mM was the optimum treatment to produce the highest biomass (fresh weight 73.6 mg and dry weight 8.2 mg).

Abstract

Molecular Genetics has a positive impact on life. The SMA/MA curriculum has included this material as a mandatory subject for grade 12th. There are obstacles to its implementation due to teachers' lack of understanding and skills. The purpose of the community service program is to improve the competence of SMA/MA teachers in the molecular field, especially those who are members of MGMP Bojonegoro Regency. The activity was conducted on Saturday, August 30, 2025, at the Molecular Genetics Laboratory of the Biology Department, Airlangga University. A total of 25 participants attended this activity, which was coordinated by the Chair and Secretary of MGMP. Participants were given lectures and practicums on the technique of using micropipettes; isolating DNA and measuring its purity; and principles and materials for DNA amplification with PCR and electrophoresis. Referring to program results (1) an increase in highest score range during post-test (range 61-80 = 44%) compared to pre-test (range 21-40 = 60%), (2) highest score achieved by participants (pre-test = 70 is 4%, post-test = 90 is 20%) (3) percentage of increase in participants scores of more than 100% is 52%, (4) participants gave scores on satisfaction index above 95%, it can be concluded that this program can improve competence of Biology teachers at SMA/MA Bojonegoro Regency. This competency improvement is an effort to support the learning process and enhance the quality of education at the SMA/MA level, enabling students to excel in science.
