AbstractAdhesion strength in sputter-deposited Cu thin films on various types of barrier layers was investigated by scratch test. The barrier layers were Ta1-xNx with varied nitrogen concentration of 0, 0.2, 0.3, and 0.5. Microstructure observation by TEM indicated that each layer consists of mixed phases of β;-Ta, bcc-TaN0.1, hexagonal-TaN, and fcc-TaN, depending on the nitrogen concentration. A sulfur- containing amorphous phase was also present discontinuously at the Cu/barrier interfaces in all samples. Scratch test showed that delamination occurred at the Cu/barrier interface and that the overall adhesion strength increased with increasing the nitrogen concentration. A good correlation was found between the measured adhesion strength and the composing phases in the barrier layer.

This study aims to develop a performance assessment instrument for Make up Training Subject in Beauty Education Program by appropriate validity and reliability procedure in thedevelopment of the assessment instrument as the assessment process and products. Thisresearch is a development research (R&D). The research focuses on the development ofassessment instrument for Makeup Training Subject. The aspects of research, data sources, techniques and instruments/data collection instrument, and validation and reliability of theinstrument used in the study conducted by interview, observation, and literature and documents.The data of this study is quantitative data, which was statistically analyzed due to relevant empirical testing (validation of instruments) that includes testing and content validity andinternal validity. Descriptive analyzes were undertaken to describe the research data. The results showed: 1) The design of the instrument Makeup Training Subject are developed through theneeds analysis. It is done through literature review and study of the course competencies byengaging a team of researchers. This study resulted in the instrument guidelines and assessment instrument completed with its scoring rubrics. The instrument comprising: a step of validityassessment is done through the stages: experts judgment, empirical tests to prove the validityand reliability of the instruments assessment. All the performance test instrument developed is
