Comparison of static-mixer and blade agitator reactor in biodiesel production

Posted Posted in Publikasi Internasional, Publikasi Internasional, Year 2010, Year 2010

Abstract. One of the difficulties faced in the current technology for biodiesel production is the requirement for rigorous mixing of methanol with the feedstock oil in the reactor. Utilization of blade mixer is limited by the immiscible state of those substances. This research is devoted to the assessment of static-mixer utilization in a transesterification reactor […]

Screening of pepper accessions for resistance against two thrips species (Frankliniella occidentalis and Thrips parvispinus)

Posted Posted in Publikasi Internasional, Publikasi Internasional, Tahun 2011, Tahun 2011

Abstract. Thrips are damaging pests in pepper worldwide. They can cause damage directly by feeding on leaves, fruits or flowers, and also indirectly by transferring viruses, especially tomato spotted wilt virus (TSWV). Although thrips are among the most damaging pests in pepper, until now there is no commercial variety with a useful level of resistance […]

Polymorphic Marker Designed from Bioinformatics Sequences Related to Cell Wall Strength for Discrimination of Mangosteen (Garcinia Mangostana L.) Clones Resistant to Gamboge Disorder

Posted Posted in Publikasi Internasional, Year 2012

Abstract. Gamboge disorder (GD) or fruit damage by the yellow sap is a major problem in mangosteen. Mangosteen plants varied in the level of GD, from very low or non GD to low, moderate and high GD. However it was difficult to differentiate between GD and non GD plants because evaluation of the disorder is […]

USE OF YEAST ANTAGONIST CRYPTOCOCCUS TERREUS TO CONTROL PETAL BLIGHT OF DENDROBIUM CAUSED BY CURVULARIA PALLESCENS

Posted Posted in Publikasi Internasional, Publikasi Internasional, Year 2013, Year 2013

Abstract. This research sought to obtain a superior yeast antagonist as a biological control agent of petal blight disease of dendrobium, to study the mechanism involved in biocontrol activity of yeasts and to study the effectiveness of yeast antagonists under field conditions. Five yeast isolates were investigated for their antagonistic activity in-vivo on detached petals, […]

GENETIC ANALYSIS FOR RESISTANCE TO ANTHRACNOSE CAUSED BY Colletotrichum acutatum IN CHILI PEPPER (Capsicum annuum L.) USING DIALLEL CROSSES

Posted Posted in Publikasi Internasional, Publikasi Internasional, Year 2013, Year 2013

Abstract. Anthracnose caused by Colletotrichum acutatum is one of the most destructive diseases of chili pepper in Indonesia. Genetic analysis for chili pepper resistance to anthracnose caused by C. acutatum was evaluated by full diallel analysis. The F1 and parent plants were grown in randomized complete block design with four replications. Forty green chili pepper […]

Genetic Parameter Estimation of Root Morphophisiology Characters of Zea mays Strains Tolerant Acid Soil

Posted Posted in Publikasi Internasional, Publikasi Internasional, Year 2013, Year 2013

Abstract. Eight strains of Zea mays were used as plant material to estimate the genetic parameters of root morphophysiology character and obtain root morphophysiology characters that can be used as selection criteria on acid soil. Plant is planted in Rhizotron pots. Information about estimation of genetic parameters, covering genetic diversity and heritability, correlations between morphophysiology […]
