Judul: Aktivitas antimikroba ekstrak jahe (Zingiber officinale Roscoe) terhadap beberapa bakteri patogen
Abstrak: hazards to the human health. Ginger (Zingiber officinale Roscoe) is commonly used as traditional medicine. It has a potential as antimicrobial agent by inhibit or kill microbes in dose dependent manner. The principle compounds of ginger are essential oils and non volatile compounds which maximum have antimicrobial activity. The objectives of this research are: (1) to study the yield of ginger extracts by multistage maceration with different polarity solvents, (2) to study antimicrobial activity of hexane, ethyl acetate and ethanol extract of ginger against foodborne pathogen such as Staphylococcus aureus, Bacillus cereus and Salmonella enterica serovar Typhimurium. Ginger extracts were prepared by multistage maceration method using solvent hexane, ethyl acetate and ethanol. The ginger extracts were assayed for antimicrobial activity by agar well diffusion method with Diameter Inhibition Zone (DIZ) and dillution broth method. The yield of hexane, ethyl acetate and ethanol ginger extracts from multistage maceration were respectively 3,57; 3,17; 3,02 g/100 g dry ginger. The DIZ value for Staphylococcus aureus were 5,0; 5,7; 1,3 mm with hexane, ethyl acetate and ethanol ginger extracts respectively 6,1; 6,6; 6,0 mm for Bacillus cereus and Salmonella Typhimurium were show no inhibitory zone. This results showed that the ginger extracts from multistage maceration have a weak antimicrobial activity (1,3 – 6,6 mm) against Gram-positive bacterial. The inhibition activity was determined for ethyl acetate ginger extract that showed the relatively highest inhibition zone. The minimum inhibition concentration did not reach in a range concentration between 5 – 20 mg/ml against Staphylococcus aureus and Bacillus cereus, therefore ginger extracts from multistage maceration with rotavapor temperature 50 o C and freeze dry process were not efficient to developed as natural antimicrobial.

Judul: Rancangan Peta Talenta (Talent Pool) Pada Direktorat Produksi PT MNC Pictures (MNCP)
Abstrak: Talents are the differentiating factor organizational performance. The company wants to grow and improve the business would not want to have to devote himself consciously seek, attract and retain the best people. To continue to improve the quality and production program to compete in the future, PT MNC Pictures (MNCP) through the production directorate should have the best human resources. The best Human resources are human resources has advantages that will become the future leaders of a company or what we call talent. The purpose of this study is to design of talent pool on the production directorate MNCP such as find the amount of talent inventory the production directorate PT MNC Pictures (MNCP), identifying core competencies the production directorate PT MNC Pictures (MNCP), do talent selection the production directorate PT MNC Pictures (MNCP), design of talent pool the production directorate PT MNC Pictures (MNCP), do talent development for the the result of talent pool in the production directorate PT MNC Pictures (MNCP). Design of Talent Pool on the production directorate MNCP is using Analytic Hierarchy Process (AHP) - pairwise compiration developed by prof. Thomas Lorie Saaty of Wharston Business school. According to experts, hrd, four core competencies possessed by MNCP, relationship is the most important core competencies possessed by the talent in MNCP, second and third order is Leadership and management and execution skills. Technical and proffesional competence is ranked last. Results of talent pool design on the production directorate MNCP is 3 employees in category deadwood, 2 employees doubtfull, 8 employees in the category mediocare, 1 employee in promising, 4 employees in career person and 4 employees in star position player.
