Abstract

Cocoa is one of the export commodities that have great prospects. The quality of cocoa in Indonesia are not satisfactory, this is caused by cocoa mealybug (Planococcus minor). Gamal (Gliricidia maculata) contains flavonoid compounds which can be used as bioinsecticides. The aims of research to determine the characteristic of flavonoid compounds in gamal leaf powder which is effective for kill of cocoa mealybug P. minor. Extraction and spectroscopy analysis (UV-Vis and FTIR) were done in the Integrated Laboratory of Technology Innovation Center (ILTIC) and the bioassay was done at Zoology Laboratory of Unila. The results shows that the crude water extract of gamal leaf powder North Lampung Cultivar (NLC) more effective killed lower than purified water extract. It was indicated by value of LC50.72hours the crude water extract than purified water extract (0.11%: 0.27%). The flavonoid compounds of gamal leaf powder NLC have the characteristics of blue fluorescence in UV light λ 254 and 366 nm. The flavonoid with the maximum peak of wavelength 310 could be grouped to flavonone with structural frame O-H, C=O carbonyl, aromatic C=C, and C-O.

Abstract

Insects are invertebrate animals with diversity and have a high adaptability. Insects have properties that are very sensitive to light, especially night insects. Night insect species in the Liwa Botanical Garden (KRL) have not been identified. This research was conducted from October to November 2019 in the Liwa Botanical Garden, West Lampung Regency. The purpose of this study was to determine the effect of the color of the lights (red, yellow, blue and white) on the presence of night insects on KRL. This research was conducted using the Purposive Sampling method using red, yellow, blue and white light. The insects that were caught were identified in the Zoology Laboratory of the Faculty of Mathematics and Natural Sciences Unila and analyzed descriptively based on morphological similarities with the book Borror et al., (1992). The data obtained were analyzed using the ANOVA test using Minitab 19. The results of this study showed that in the Araceae area of the Taman Liwa Botanical Garden the blue light traps caught a maximum of 457 night insects while the red light traps caught the night insects with the least number 19 tail. This study also showed that light intensity correlated with the number of night insects obtained.

Abstract

Moths are insects that belong to the Lepidoptera Ordo. Moths are attracted to volatile compounds. The examples of volatile compounds include alcohol, urea, and acetic acid. Pineapple, banana and tapai are three types of bait that will be used in this study, because all three types of bait contain volatile compounds in the form of scents that strong enough to attract moths. Liwa botanical garden is a recreational and educational place, located in West Lampung district, which was only approved by the Regional Government in 2007. Because there is onlya view data on the presence of moths, so it needs to conduct the research to know the variation types of moths that exist in Liwa botanical garden, West Lampung. This research is a Quasy Experiment with 3 kinds of baits, there are pineapple, banana, and tapai as a treatment with 5 replications in the form of sampling time. The result obtained that in AraceaeLiwa Botanical Garden were obtained by six families, nine genera, and nine species of moth. Nine species of moths are Nemophora sp, Nematopogon sp, Brahmaeawallichii, Rhodogastriaamasis, Creatonosgungis, Sundasceliaepelys, Rheumaptera sp, Noctua sp, and Epicnopterix sp
