Mungbean is one of important sources of vegetable protein in Indonesia. Extensification through the utilization of drylands is very potential to increase mungbean production. The study aimed to find out the response of mungbean given antioxidants of turmeric extract to drought stress. The study was conducted in Kuningan West Java in 2019. The study was designed using a randomized block design with factorial patterns and three replications. The first factor was the concentration of antioxidant of turmeric extract, namely: 0%, 1%, and 1.5%, and the second factor was soil water content namely: field capacity, 75% field capacity, and 50% field capacity. The results showed that the yield of seeds remained high even though mungbean experienced mild stress (75% field capacity) by administering antioxidant of turmeric extract as much as 1% or 1.5%. Likewise, the number of seeds and relative water content of leaves remained high with the same treatment. Meanwhile, plant height, leaf area, and number of pods were increasingly reduced by decreasing the level of soil water content, on the other hand, antioxidants increased the number of filled pods.

Bactrocera dorsalis is a very harmful pest for fruit and vegetable. Chemical control of these pests has raised another problem. The use of surian leaf extract can be a good and environmentally friendly alternative control. This study aims to determine the effect of the administration of vegetable pesticides from suren leaf extract in the control of B. dorsalis on red chili. This research had been carried out at Siliwangi University and BBPOPT, Karawang in July to August 2019. This study used a Completely Randomized Design (CRD) with six replications. The concentration of suren leaf extract were : 0%, 0.025%, 0.05%, and 0.1%. The results showed that chili fruit extracts with the highest 0.1% consistently could reduce the number of larvae and the number of fruit attacked. The main compounds contained in the surian leaf extract include 9,12-Octadecadienoic acid (Z, Z) -, phytol, acetate, phenol, 2-methyl-5- (1,2,2-trimethylcyclopentyl) -, (S) -, Cedren-13-ol, 8-, and 3,7,11,15-Tetramethyl-2-. These compounds were thought to be strong compounds that play a role in suppressing the number of larvae and the number of fruit attacked.

ABSTRACT This research aimed to selection the phenotype and molecular of rice lines ( Oryza sativa L.) containing Pup1 and Alt loci at various concentrations of Al and P elements in yoshida nutrient solution. This research was conducted from November 2018 to February 2019 at The Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development Bogor. The phenotype study used a Split Plot Design with two factors and repeated three times. The first factor was the variation of Al×P concentrations consisting of eight levels and the second factor was the variation of rice lines consisting of twenty levels. The molecular study used three primers to detect the rice lines with Pup1 and Alt loci. The results of the Yoshida nutrient solution showed that the A4 level of Al×P concentrations (0 ppm of Al×15 ppm of P) had the best average of other levels. In rice lines with Pup1 loci G4 [10B (B4-SK4)] showed the highest average on the root dry-weight parameters. In rice lines with Pup1 and Alt loci G11 [35(21(B15)-3] showed the highest average on the root dry-weight parameters at the A2 level of Al×P concentrations (0 ppm of Al×5 ppm of P) for Pup1 loci and A6 level of Al×P concentrations (60 ppm of Al×5 ppm of P) for Alt loci. In the molecular study, three primers can detect the rice lines that contained Pup1 and Alt loci. K46-2 specific primer detected the Pup1 loci with the comparison of Kasalath rice variety. RM12031 and RM1361 primers detected the Alt loci with the comparison of Dupa rice variety.

ABSTRACT Orchid plants are one of the ornamental plant commodities that have no food reserves in their seeds and have very fine and small seed sizes making it difficult to propagate naturally. One alternative for the propagation of this plant is to carry out vegetative propagation in vitro or tissue culture. The success of plant tissue culture can not be separated from the role of media composition used. Leaf fertilizer is one of the alternative media that can be used as media material in orchid plant tissue culture because leaf fertilizers contain macro and micro nutrients that can provide nutrient intake to explants to support the growth and development of these explants. Propagation of Dian Agrihorti Dendrobium orchid plant in vitro through callus proliferation using different brands of leaf fertilizer media namely leaf fertilizer hyponex brand and growmore brand. The results of the observation showed that the most proliferative Embryogenic Callus and Proliferation Rate were produced from the treatment of adding 4 ppm growmore, namely 88.42% and 322.41%.

One alternative for the propagation of this plant is to carry out vegetative propagation in vitro or tissue culture. The success of plant tissue culture can not be separated from the role of media composition used. Leaf fertilizer is one of the alternative media that can be used as media material in orchid plant tissue culture because leaf fertilizers contain macro and micro nutrients that can provide nutrient intake to explants to support the growth and development of these explants. Propagation of Dian Agrihorti Dendrobium orchid plant in vitro through callus proliferation using different brands of leaf fertilizer media namely leaf fertilizer hyponex brand and growmore brand. The results of the observation showed that the most proliferative Embryogenic Callus and Proliferation Rate were produced from the treatment of adding 4 ppm growmore, namely 88.42% and 322.41%.

ABSTRACT Chili grows well both in lowland and highland, and as a high economic vegetable chili is widely grown by farmers. Nevertheless, there are still many obstacle in its management among others is pest and disease attack. Antracnose disease by Colletotrichum sp. causes yield decrease even harvest failure as it attacks the fruits. The objective was to find out kinds of biopesticides and its concentration to control antracnose disease. The experiment was conducted in Faculty of Agriculture garden from July until February 2017. A Randomized Block Design was used consisted of 9 treatments i.e. A (control), B (1% soursop extract), C (2% soursop extract), D (1% siam weed extract), E (2% siam weed extract), F (1% galangal rhizome extract), G (2% galangal rhizome extract), H (1% mixture of soursop, kirinyuh, and galangal rhizome extract), and I (2% mixture of soursop, siam weed, and galangal rhizome extract). The results that the efficacy of application of 1% to 2% extracts of soursop leaf, siam weeds, and galangal rhizome, both independently and in mixture, were in the range of ineffective and less effective categories in controlling antracnose disease on red chilli.
