FORMULASI TABLET EKSTRAK DAUN SAMBILOTO (Andrographis paniculata N.) SECARA KEMPA LANGSUNG DENGAN KOMBINASI MANITOL – SORBITOL SEBAGAI BAHAN PENGISI

It has been conducted research about Tablets Formulation of Creat (Andrographis paniculata N.) Leaves Extract in Directly Compressed with Combination of Manitol-Sorbitol as Filler Materials. The result of test shows that every formula fulfills test conditions of quality for uniformity of weight, brittleness, size measure and hardness, such as those which qualified by Farmacope Indonesia and other monographs. Statistical test using Ansira (Variance Design Analysis) indicates that usage of filler materials combinations mannitol – sorbitol for formula I, II and III respectively 50% : 50%, 75% : 25% dan 25% : 75%, yield no significant effect for physical quality tablet

The Impact of Humor on Attitudes toward Persons with Disabilities

The purpose of this study was to determine the impact of humor on attitudes as measured by the Modified lssues of Disability Scale (MIDS) by comparing the effects of a humorous and a serious video designed to reduce negative attitudes toward persons with disabilities. Ninety-three undergraduate students at a southeastern university volunteered to. participate in the study. The participants were randomly assigned to one of three treatment groups. The first group viewed a serious video concerning disability, the second group viewed a humorous video concerning disability, and the third group viewed no video. A one-way model analysis of variance design was applied to the MIDS scores (dependent variable). Results revealed no significant differences between the attitude scores of the three groups. The results of the study highlight the need for further research on the impact of humor on attitudes toward persons with disabilities.

A Covariance Controller Design Incorporating Optimal Estimation for Nonlinear Stochastic Systems

This note addresses the problem of constrained variance design with minimizing LQG cost function via the method of covariance control incorporating the optimal estimation for nonlinear stochastic systems. The nonlinear stochastic systems are first linearized and then are examined by way of the technique of describing functions. Finally, an application of this approach to a position servomechanism is illustrated by a numerical example.
