Abstract

The community service activities have been carried out at Madrasah Aliyah Masyhudiyah Gresik. Thepurpose of service is: 1) providing understanding to teachers in making learning material throughYouTube, 2) providing motivation to teachers, 3) building teachers' confidence, and 4) using YouTube forfun learning tools. Methods of activities are lectures, demonstrations, workshops and training using theCamtasia application. Data collection techniques are based on the results of the pretest - posttest andparticipatory approach. Data analysis to measure the success category is done by calculating thepercentage of correct answers for each aspect asked, the percentage of learning videos made and thenumber of learning videos uploaded. The results of the activities are: 1) the teacher's understanding inmaking construction of video-based learning materials on average increased by 52%, 2) 100% of teachershave made videos for learning media using the Camtasia application, 3) 30% of teachers have uploadedlearning videos on social media YouTube This activity resulted in an increase in teacher understandingrelated to the importance of using YouTube as a learning medium and videos containing learning materialscreated by madrasa teachers.

Abstract

A bipotentiometric FIA system has been developed for the determination of vitamin C. The system was a single stream manifold, which consisted of a peristaltic pump, a self made injector with internal loop and two Pt-electrodes connected to a PC by serial ADC or parallel ADC interface card. One of the Ptelectrodes was located in the injector before the internal loop, while the other electrodes at the end of the TEFLON reaction tube. The PC was supported with a self-made software for controlling the pump, signal acquisition, processing, and visualisation, and further peak determination, followed by calibration of standard solutions and calculation of sample concentrations. The above FIA-system configuration was applied to determine vitamin C by the injection of sample solution into a stream of potassium hexacyanoferrate (III) solution. The optimum result was achieved with knitted tube reaction of 0.8 mm i.d., 50 cm length, at flow rate 0,64 ml/minute, and consumed 3.6 ml of carrier solution per five injection, and gave linearity range at 0.001 – 0.100 N vitamin C, with the coefficient of correlation 0.9999, RSD peak to peak better than 3.0% and the error of artificial samples were less than 3.4 %.Key Words : Bipotentiometric-FIA, injector with internal loop, module-program, vitamin C

Abstract

Resistance to the traditional antifolates is now widespread in Plasmodium falciparum and Plasmodium vivax. To find the interaction model of some compounds derived from 1,6-dihydro-1,3,5-triazine-2,4-diamine, molecular docking technique was carried out using these compounds ligand and pDHFR as the receptor. Complex ligand and the receptor from Protein Data Bank (PDB ID 1J3K) were chosen as an interaction model between a ligand and its receptor. Each compound was optimized using ab initio methods with 6-311G basis set. Partial charges of ligand were added using AM1-BCC methods. Each ligand was docked to the receptor utilizing Dock6 software. Theoretical prediction based on the binding energy between these compounds as the ligand with pDHFR as receptor resulted in 1 compound, namely 6,6-dimethyl-1-[3-(2-chloro-4,5-dibromophenoxy)propoxy]-1,6-dihydro-1,3,5-triazine-2,4-diamine possessing binding affinity better than that of WR99210 which was known to have good antimalarial activity.
