Abstract

In Simalungun Regency of North Sumatra, pest attacks of coffee fruit grinder Hypothenemus hampei Ferr are scattered throughout the coffee producing sub-district, with the intensity of moderate – heavy attacks. The widespread spread and high intensity of attacks, because generally farmers do not make control efforts by various limitations. Including technical culture practices, farmers do not all implement agronomical strategy that can prevent pest attacks. Field experimental was conducted on 2 types of coffee plantations with different of agronomical acts, using randomized design methods of series groups. Factors studied were the influence of protective trees and experiments tested 3 types of attracktant traps to control the attack of H. hampei Ferr. The research aimed to determine the incidence level of H. hampei Ferr pest attacks on protective tree-lined and treeless coffee plants and to determine the effectiveness of attracktan traps controlling coffee fruit grinding pests. To obtain the data, the experiment was made on both types of land. The calculated parameter were : (1). Intensity of attack of coffee fruit grinding pests before the installation of attracktant. (2). Number of coffee fruit grinders trapped attracktant, (3). Other types of insects trapped besides H.hampei Ferr, and (4). The intensity of coffee fruit grinding attacks after attracktant installation, was calculated using the formula: Is = {A/(A+B)} x 100% (Is = attack intensity, A = number of stricken seeds, and B = healthy number of seeds). Inferred, the intensity of attacks by coffee fruit-growing pests on coffee plantations with protective trees was lower than that of coffee plantations without protective trees. The use of attracktant traps on coffee plants with protective trees and without protective trees, is able to decrease the intensity of attacks from heavy category to medium. The effectiveness of 3 (three)attracktant types of Hypotan 500 SL, Atrakop 500 L and Koptan L to trap the pest H. hampei Ferr on a coffee field with protective trees and without protective trees was relatively no different. Keywords : attracktant; attack intensity; coffee fruit grinder; protective tree

Abstract

Temulawak (Curcuma xanthorrhiza Roxb.) is a well-known medicinal plant and widely used as tradi­tional medicine in Indonesia. Development of temulawak cultivation is suggested to be conducted under shading area such as under rubber plantation. Information on genetic variability and relationship among agronomic and metabolite traits under shading area will support the selection process of temulawak breeding by providing heritable traits which correlated to a main trait. This research aimed to provide information of genetic variability and correlation among traits which will be useful for the temulawak breeding program. Temulawak cultivation were conducted under six location of PT Perkebunan Nusantara VIII rubber plantation, West Java which consisted of two altitudes. Those were low altitude (Cikumpay, Cipeo, Pasir Salam) and medium altitude (Gunung Hejo, Gunung Nyungcung, Mengger). Randomized complete block design and 11 temulawak genotypes (A, D, F, T4, T5, T6, T11, T12, T14, T16, T17) was used in each location. Result showed different location affected almost all traits. High heritability and medium coefficient of genetic variation performed by primary rhizome fresh weight (h2bs=74,8%), total rhizome fresh weight (h2bs=66,8%), leaves width (h2bs=62,2%), secondary rhizome fresh weight (h2bs=57,9%), tiller number (h2bs=56,5%) and stem girth (h2bs=53,5%). Path analysis result revealed that plant height (r=1,877) and tiller number (r=0,915) directly correlated with total rhizome fresh weight. However only tiller number is recommended as selection trait of total rhizome fresh weight because of its high direct effect and high heritability. Keywords: heritability, metabolite, path analysis, rhizome, selection trait.

Abstract

Intercropping cropping patterns can increase the diversity and abundance of soil arthropods that can function as pest control for plants while maximizing land use. This study aims to determine the diversity and abundance of soil arthropods in the planting of monoculture chilies, intercropping with watermelon, chili intercropping with corn, and chili intercropping with corn and watermelon. The study was conducted in the Maros Regency, South Sulawesi Province, Indonesia. The study was conducted from August to November 2018. A sampling of natural enemy insects using pitfall traps installed for 1x24 hours with observational intervals every two weeks. From all of the cropping patterns, the soil arthropods that were found were spiders and several ant, namely: Odontomachus sp., Monomarium sp. and Anoplolepis sp. The insect diversity index was found to be low with an average of 0.07 in the chili cropping pattern intercropped with watermelon up to 0.17 in the monoculture chili cropping pattern and the chili cropping pattern intercropped with corn and watermelon. Soil arthropods that dominate in all types of cropping patterns were the Minimu monomorium ant species with the highest population of 2,987 individuals found in the chili cropping pattern intercropped with watermelons.

Abstract

The red flour beetle, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), is a secondary and major pest in flour processing and storage areas. T. castaneum has a wide host range such as flours made from other foods, including corn, rice, wheat, sorghum, and biscuits. The level of susceptibility of type flour corn and rice to T. castaneum infestation depends on varieties. The objective of this study was to evaluate the classification susceptibility of flour rice and corn to infestation T. castaneum during storage. The research was carried out in a form of an experimental laboratory that used a Completely Randomized Design (CRD) with treatments type flour corn and rice, each treatment was repeated four times. The data obtained were analyzed using the Analysis of Variance (ANOVA), the results data were significantly different (P <0.05) followed by the Duncan test. Measurement strength relationship between index susceptibility with the number of F1 and median development time was determined by correlation analysis. The results showed that classification susceptibility flour rice was moderate to susceptible, while flour corn was classified as moderate to susceptible and susceptible to very susceptible. The susceptibility of two types flour was determined by the number of F1 and median development time of T. castaneum. Information classification susceptibility flour rice and corn against T. castaneum can help detect damage and lose weight of flour during storage.
