Tritrophic interaction among host plant-herbivore-parasitoid involves chemical cues. The infested plant by herbivores has been reacted to produce volatiles which is a cue used by the herbivore parasitoids for host location. These volatiles can be developed to enhance natural control of insect pests, especially by optimally use of parasitoids. Egg parasitoids are biocontrol agents that play an important role in natural control of herbivores. This research used a tritrophic interaction model of rice plant-brown plant hopper (BPH)-egg parasitoid of BPH. Research on analysis of chemical cues in tritrophic interactions was aimed to identify volatiles that are used by the parasitoid to find its host. The volatiles that effectively affect the parasitoid orientation behavior could be developed into a parasitoid attractant. Extraction of volatiles as the egg parasitoid cues was done using soxhlet, and identification of the volatiles using Gas Chromatography-Mass Spectrometry (GC-MS). Bioassay of the volatiles on the BPH parasitoid orientation behavior was performed using Y-tube olfactometry. The volatiles that are used for host location cues by the parasitoid affect the parasitoid orientation behavior by showing the preference of the parasitoid females to the odor of volatile. Volatiles extracted from BPH-egg-infested plants and uninfested plants contain alcohol, hydrocarbon, and ester compounds. Based on the difference of the compound composition of both extractions, five compounds of long-chain hydrocarbon, both branched and unsaturated compounds are the main volatile components which caused positive orientation behavior of the egg parasitoid. The egg parasitoids showed positive behavior orientation toward the volatiles extracted from BPH-egg-infested plant. Those hydrocarbon compounds are potential materials to be developed into bio attractants of BPH egg parasitoid.

Physical and chemical interactions are the principles for different types of separation systems as the equillibrium dynamics on surface plays a key-role. Surface modification is a way for selective separation at interfaces. Moreover, synthesis of gel silica by a sol-gel method is preferred due to the homogeneity and surface feature easily controlled. Cellulose can be added in situ to modified the silica features during the process. Further application for to study interaction of rhodamin and tartrazine in its surface and their solubilities in mobile phase explains the possibility for their separation. This paper devoted to evaluate the surface behavior in term of adsorption and desorption of tartrazine and rhodamin on silica-cellulose thin layer in different mobile phase. Some carrier liquids applied such as methanol, acetone, n-hexane and chloroform. The result proves tartrazine and rhodamin is separated and have different behavior in different mobile phase. The retardation factors (Rf) of the mixtures suggest complexity behavior on silica-cellulose surface.

Abstract: Research and development of the BPBL’s teaching materials (Blended-Problem Base Learning) aim to measure its effectiveness on students learning outcomes (in extraction and chromatography courses) and their soft skills. Based on the preliminary questionnaire regarding the need for the development of the BPBL’s teaching materials states that the students felt quite difficult to understand the concepts in extraction and chromatography so their learning outcomes does not meet the standards. Students also realize that improving their soft skills is important for personal development, social participation, and success in the work environment. BPBL’s teaching materials are a combination between blended learning and problem-based learning. Using coffee as daily content is used to give meaningful learning for students and aim them to easily understand the concept in extraction and chromatography courses. The effectiveness of BPBL’s teaching materials on learning outcomes of students with n-gain is 0,64 or 64% and the effectiveness on soft skill of students with n-gain is 0,31% or 31%, both are included in the medium effectiveness category. Abstrak: Penelitian dan pengembangan bahan ajar berbasis BPBL (Blended- Problem Base Learning) bertujuan untuk mengukur efektifitasnya terhadap hasil belajar (pada materi ekstraksi dan kromatografi) dan soft skill mahasiswa. Angket pendahuluan mengenai perlunya pengembangan bahan ajar berbasis BPBL menyatakan bahwa mahasiswa merasa cukup kesulitan untuk memahami konsep pada materi ekstraksi dan kromatografi sehingga nilai hasil belajar mereka kurang memenuhi standart nilai yang ditentukan. Mahasiswa pun menyadari pentingnya meningkatkan soft skill yang mereka miliki untuk perkembangan pribadi, partisipasi sosial dan kesuksesan di lingkungan kerja. Model BPBL merupakan gabungan dari model pembelajaran blended learning dengan problem base learning. Penggunaan topik kopi sebagai konten sehari hari dalam pembelajaraan bertujuan untuk memberikan pembelajaran yang bermakna terhadap mahasiswa dan memudahkan mahasiswa untuk memahami konsep dalam ekstraksi dan kromatografi. Keefektifan bahan ajar berbasis BPBL terhadap hasil belajar mahasiswa menggunakan n-gain adalah sebesar 0,64 atau 64%, sedangkan keefektifan bahan ajar berbasis BPBL terhadap soft skill mahasiswa menggunakan n-gain adalah sebesar 0,31 atau 31%.
