Radio is an audio medium used to fulfil the needs the audience's need, both for information and entertainment. Radio provides a variety of information content and a choice of music. Amid technological developments, the presence of many choices of media to access news, entertainment, music, and other information has become a challenge for radio broadcasting. Now people have various choices of media to get information and listen to music. This research aimed to look at the choice of media, especially radio, from the audience and find out what makes radio remains the audience's choice for information, entertainment and listening to music compared to other new media, including the reasons and motivations of audiences to listen to the radio. The results showed that audiences tended to prefer radio over other media because radio offered unique things, for example, the element of 'surprise' in selecting songs that give different sensations. In addition, the presence of radio broadcasters is also considered entertaining and can be a companion to the audience, especially when travelling. These results indicate that radio offers a uniqueness that cannot be found in other media, and the audience is free to choose the media based on their motivations, the greatest of which is listening to the radio for music, entertainment, and information.

Hibiscus rosa-sinensis is a plant that has flowers with many variations in size, petal shape, petal colors, and chromosome number. Chromosome number and morphology information is the key to study its flower morphology and physiology. Chromosome Image Analyzing System IV (CHIAS IV) is software that used for mapping and identifying chromosome automatically. This report presents the results of chromosome analysis using CHIAS IV from four H. rosa-sinensis flower variations (single small red, single small pale red, single big red, and double red). Chromosome number and condensation patterns of individual chromosomes analysis suggested that these flower variations of H. rosa-sinensis exhibited polyploidy, with the smallest number found in single small pale red and the biggest number in single big red flower. CHIAS IV software is an effective tool to analyze chromosome image, especially to predict chromosome number, chromosome type, relative length, and condensation patterns of individual chromosome.
