This research aims to study the application of kaolin with coconut fiber corncobs fiber and durian peel in concrete masonry unit wall for increasing effective heat protection and lightweight. The ratio of cement type 1: kaolin is equal to 1: 60 by weight. The kaolin is replaced by fiber include coconut fiber corncob fiber durian peel fiber with 1.67% 3.33% and 5% by weight of kaolin. The kaolin concrete block mixed with fiber sample size is formed to 6.9 x 39 x 19 centimeter with the hydraulic compactor. The samples tested in physical and mechanical properties follow the TIS 58-2533 standard. Resulting their fibers can reduce the density thermal conductivity and compressive strength and increase the changing length and water absorption of kaolin concrete blocks. The kaolin concrete block without fiber has highest compressive strength followed by the kaolin concrete block mixed with corn cob fiber the kaolin concrete block mixed with coconut meal fiber and the kaolin concrete block mixed with durian peel fiber has lowest compressive strength respectively. However their fibers have possibility to be composite materials to reduce weight of kaolin concrete blocks

This study aims to develop a new evaluation technique for Northern Corn Leaf Blight (NCLB) resistance in maize under greenhouse condition. Ki48/Ki47 F2 (160 lines) and 2 commercial verities (Hi-Brix3 and Insee2) were evaluated. For this technique 10-14 day old seedlings (4-5 leaves) were sprayed with ACIL1 spore suspension (104spores/ml.) for infection. The results of this technique correlated with the results from the common technique under field condition which used 21-25 days old seedlings (6-7 leaves) (correlation value = 0.658). This evaluation technique was used to assist in QTL mapping of NCLB resistance. Population of Ki48/Ki47 F2 (160 lines) were analyzed for QTL mapping by using Simple Sequence Repeats (SSR) markers. It was found that major parental polymorphism located on chromosome 5 and chromosome 8. When Single QTL analysis was performed SSR marker UMC1365 could clearly indentified qualitative trait loci on chromosome 5 and SSR markers UMC1095 UMC1268 and UMC2356 could clearly indentified qualitative trait loci on chromosome 8.
