Before attempting a small-scale field trial of the sterile male method to reduce blackbird population levels, laboratory studies were undertaken, in 1978 and 1979, to evaluate the efficiency of thiotepa as a bird sterilant. The LD50 of thiotepa was determined (6.2 mg/kg of body weight), as well as the applicable dose to produce sterility (4.32 mg/kg of body weight) without causing mortality, following a treatment beginning on April 25, 1979. This dose inhibited testicular growth for about 1 month. During this period, testes weight of treated redwings was only 10% of normal weight. Identical doses to those administered to male redwings produced the same effects on testicular development of grackles and cowbirds. No effects were noted on the testes weight of male Red-winged Blackbirds 1 year after treatment with thiotepa. Results indicated that the sterile male approach may have potential to reduce blackbird populations causing crop damage.

This study aims to develop E-Learning learning media and test the validity of Android-based Smart Apss Creator (SAC) products for transvision sales employees in Jakarta. Using the Research and development method. The development step refers to the Bord & Gall development model. There are 10 steps in the development of Borg & Gall, but this research is limited to 9 steps, namely research and collection of initial information, planning the initial product format development of the initial trial, product revision, small scale field trial, product revision, scale field trial the size and revision of the final product. The population in this study were 10 employees of PT. Transvision Jakarta sellers. The research sample goes through 3 stages, namely the User-Test (one-to-one), the Small Group Test and the Field Test. This SAC software contains information about the history of the company, the company's vision and mission and the products of the Transvision Company. Product development after validation by 3 media experts and by 3 material experts get a score of> 83 which indicates that this application is feasible to be implemented. Try out the use in 3 stages, one-to-one evaluation with 84% results, Small Group evaluation 83% then 83% field evaluation which shows that the application of the development is feasible to use.
