No full textWhite Jabon (Anthochepalus cadamba Miq).  is one of the tree species that has high prospects for industrial plantations and reforestation (greening) in Indonesia because it has very fast growth, very good adaptability. Disorders of plant disturbance organisms most commonly found in Jabon, Jabon caterpillar (Arthroschista hilaralis) become a major problem that can reduce the quality and quantity of wood. Pest control with chemicals does not provide maximum results so it is necessary to test with biopesticides. The study to examine the effect of gamal leaf extract as a natural insecticide was carried out using a completely randomized design with four treatments, namely the concentration of gamal leaf extract 0% (P0), 50% (P1), 75% (P2), 100% (P3). The results showed that gamal leaf extract as a vegetable insecticide had a positive effect on the mortality of A. hilaralis larvae in Jabon plants. The higher the concentration of gamal leaf extract, the higher the mortality rate in A. hilaralis larvae. This can be seen in the most effective concentration is the concentration of 100% with a mortality rate of 95%. The highest total mortality of A. hilaralis larvae occurred at a concentration of 100% ie 2.1 head / day. The higher the concentration of gamal leaf extract, the higher the speed of death of the larva

Selection of Chilli Pepper (Capsicum frutescens L.) for Salinity Tolerance in Seed Germination
Get PDFThe obstacle of chilli pepper development in saline is that there is no salinity tolerant variety, so it is necessary to assemble tolerant varieties. Information on tolerant genotypes, selection criteria and determination of new selection methods at the germination level are needed to make it easier for breeders to select prospective tolerant varieties early. This study aims to determine tolerant genotypes, appropriate selection criteria and NaCl concentrations used for selection at the germination level. The study was arranged based on a completely randomized design with two factors: NaCl concentration and some chilli pepper genotypes. NaCl solution concentrations consist of five concentrations of N0: 0 g L-1 (EC 291 µS/cm, SAL 0,10), N1: 2 g L-1 (EC 3,71 ms/cm, SAL 2,0), N2: 4 g L-1(EC 6,60 mS/cm, SAL 3,60), N3: 6 g L-1 (EC 9,56 mS/cm, SAL 5,40) and N4: 8 g L-1 (EC 12,45 mS/cm SAL 5,40). The second factor is the genotype of chilli pepper consisting of 22 genotypes. The results showed that the most tolerant genotypes were G4, G7 and G15. Characters that can be used as selection criteria at the germination level are the percentage of germination, radical and hypocotyl length. The concentration of 8 g NaCl L-1 is effectively used to select tolerant genotype
