This study aims to analyze Arabic learning by using a blended learning approach in management perspective. This study uses a qualitative approach with case study, with a research site at the Madrasah Aliyah Lubbul Labib, Maron, Probolinggo, East Java, Indonesia. The results showed that; Arabic learning management is carried out through several stages, namely; planning, which includes learner analysis, state objectives, determination of material, methods, approaches, media and evaluation techniques that will be used in learning activities. Furthermore, the results of the planning are implemented in online learning activities and evaluated according to what has been planned.

The extraction process is a crucial part of the synthesis of Molecularly Imprinted Polymers (MIP). The process will have a significant impact on the number of its cavities that affects the polymers’ ability to recognize targets with the same physical and chemical properties as the analytes. Caffeine polymers have been prepared by the cooling-heating method using methacrylic acid (MAA) as a monomer, ethylene glycol dimethacrylate (EDMA) as a crosslinker, benzoyl peroxide (BPO) as an initiator, and chloroform as a solvent. The resulting caffeine polymer powder was extracted using chloroform, methanol / acetic acid (1:20), and methanol, respectively. Finally, the polymer powder is washed using the aquabidest, which is heated at 60°C. The results of FTIR, XRD, and SEM characterization showed that caffeine concentration was significantly reduced. The number of cavities obtained from caffeine MIP is 604 more than before extracted, which is 132 pieces.

Bi-directional interaction between economically important fungal pathogen Botrytis cinerea and aphid Myzus persicea causes serious economic losses to the crop plants resulting in loss of both time and money spend. In bi-direction interaction the fungal pathogen and insect herbivores, can both interact directly with the plant and interact indirectly with each other as they struggle to compete for the resources of the plant. We investigated the bi-directional interaction between the necrotrophic and economically important fungal pathogen Botrytis cinerea Pers Fr (Helotiales Sclerotiniaceae) and the aphid Myzus persicae (Hemiptera Aphididae) on plant host, lettuce Lactuca sativa (Asteraceae: Compositae). Botrytis cinerea on host plant causes a brownish discoloration of the leaf petiole accompanied by the rotting of the leaves, however, presence of aphids on lettuce plants causes' economic damage directly through injury and indirectly through virus transmission, resulting in wilting and head contamination.In this study, it was found that negative interaction between B. cinerea and Myzus persicae was established. The presence of fungal pathogen B. cinerea and Myzus persicae stressed the host lettuce plant, resulting in significant reduction in the rate of photosynthesis and chlorophyll fluorescence, and reduction in the dry shoot and root weight of the lettuce plant. The study established that aphid population growth rate and the number of B. cinerea lesions decreased when both were present on the same host plant.
