Abstract

This research is focused to use a picture as a media to teach descriptive text to VIII graders at SMPN 4 Palangka Raya. This media aims to build the will of students to learn and help them to understand descriptive text, since English is hard subject to teach. Interesting media to attract students’ attention in teaching learning process is important, especially many students in SMPN 4 Palangka Raya find that English subject is hard and boring, they immediately lazy to study even just by listen to name of the subject, shows how essential to build a good atmosphere in the class. This research determined how using pictures as a media improve students in learning descriptive text. This research used one group pre-test and post-test pre-experimental design. This research instrument was a test and VIII grade students in SMPN 4 Palangka Raya as a subject. The mean score formula was implemented in this research to analyzing the data. The results showed that picture as a learning media is indeed affects students learning outcomes in terms of descriptive text. Researcher founds that picture as a media help teacher to increase students’ enthusiasm in learning, since it attracted students’ attention and make teaching learning process more interesting.

Abstract

In the production of coated particles that meet the requirements for high temperature gas reactor fuels, one of quality control requirements for the kernel is diameter control. The study was conducted by varying the diameter of the nozzle for predicting the size of gel diameter obtained from external gelation process by correlating variables of feed density, feed viscosity, feed solution tension and nozzle diameter quantitatively with dimensional analysis method in the form of dimensionless numbers. Fabrication of CSZ kernel was done by preparing the feed solution, which consists of a mixture of ZrO(NO3)2.2H2O and Ce(NO3)3.6H2O, urea, tetrahydrofurfuryl alcohol (THFA) and poly vinyl alcohol (PVA). External gelation is performed by dripping sol feed solution through a nozzle into gelation column containing ammonium hydroxide solution to form CSZ gel. Droplet formation occurs when the feed solution passes by the nozzle. The diameter of the gel formed can be calculated by correlating nozzle diameter and physical properties of the feed solution using dimensional analysis. Gel diameter of the experimental results was measured using an optical microscope. The diameter of the gel obtained from the dimensionless number equation shows results that are not too different from the diameter of the experimental gel with some deviations in the data. Data of diameter measurement of experimental gel and data of calculation by dimensionless equation show that diameter of the nozzle is directly proportional to diameter of the obtained gel.
