Success in cultivating potatoes is the use of good quality potato seeds. Good quality potato seeds are produced through several stages starting from in vitro culture to extension seed production. One of the important stages in potato seed production is the production of first generation (G1) potato seeds. Efforts to increase the yield of G1 tubers can be made through modifying the planting media and applying growth regulators. This research aims to produce G1 potato tubers by adjusting the composition of the planting media and applying a growth inhibitor. The research consisted of two series of experiments. Each experiment was carried out using a Completely Randomized Design with six treatments, each repeated four times. Experiment 1: a. Cocopeat (CP) 100% + charcoal husk (CH) 0%; b. CP 20% + CH 80%; c. CP 40% + CH 60%; d. CP 60% + CH 40%; e. CP 80% + CH 20%; f. CP 0% + CH 100%. Experiment 2: a. Daminozide 0 ppm; b. Daminozide 500 ppm; c. Daminozide 1000 ppm; d. Daminozide 1500 ppm). From the research results it can be concluded: (1) Composition treatment CP 60% + CH 40% is the best treatment for the growth and number of G1 potato tubers; and (2) The best concentration of daminozide for the growth and production of G1 potato seed tubers is 3500 ppm.

The aim of this study was to investigate how the application of various concentrations of cytokinin affects the shoot multiplication in two varieties of banana ( Musa acuminata L.). The research was conducted at the Plant Physiology and Biotechnology Laboratory, Faculty of Agriculture, University of Sultan Ageng Tirtayasa. The study was designed as a Randomized Complete Block Design, consisting of two factors. The first factor included two types of banana varieties: Bagja and Cavendish. The second factor included six types of application of various concentrations of cytokinin, which were 1 mg/l BAP, 2 mg/l BAP, 3 mg/l BAP, 1 mg/l kinetin, 2 mg/l kinetin, and 3 mg/l kinetin. The results showed that there was a significant difference in the effect of cavendish banana varieties explant on the height of the plant, with an average value of 3.26 cm. The application of various concentrations of cytokinin didn’t show a significant effect on the parameters of the height of the plant, shoot emergence time, number of shoots, and time of root emergence.

Efforts to increase eggplant productivity are often constrained by plant damage by phytopathogens and pests. The use of secondary metabolites which are the result of the metabolism of biological agents for the control of phytopathogens and destructive pests in plants, and this is an environmentally friendly control measure. This study aimed to examine the use of secondary metabolites of Trichoderma harzianum to control fruit rot disease Phomopsis vexans and leaf destroying pests of Epilachna sp., and to increase eggplant yield. The treatments tried were secondary metabolites with concentrations of 0%, 10%, 20% and 30%. The results showed that treatment of secondary metabolites of T. harzianum suppressed fruit rot disease Phomopsis, but had no effect on leaf damage by Epilachna. Treatment with a concentration of 10%, 20% and 30% respectively can reduce the intensity of the disease 51.65%, 64.25% and 69.63%. Leaf damage by Epilachna sp. was classified as mild for all concentration levels, ranging from 3.65 to 4.32%. Treatment of T. harzianum secondary metabolites with various levels of concentration affected on the fruit length, but did not affect on number of fruit, fruit diameter, and fruit weight.
