Performance management in question is with the aim of increasing the strategic focus and effectiveness of the company in ensuring continuous improvement of individual and team performance. The most popular approach is to use the BSC (Balanced Scorecard). Cafe Red&Blue wants to grow and maintain its business. Therefore, in this study we want to design an instrument for measuring performance at Red&Blue cafes using the BSC. The initial stage in designing the instrument is to conduct internal and external analysis to determine the position of the business in the industry and the strategy that must be used. The SWOT approach is used in the analysis of the internal and external environment. From the SWOT analysis, it can be seen that the Red&Blue cafe is in quadrant I position. The strategy that must be applied is an offensive and defensive strategy as a complement. This strategy requires Red&Blue to improve its marketing strategy in order to bring even greater opportunities to the business. The next stage is through the formulation of strategic objectives, the objectives of which are designed; increase profits, increase customer loyalty, improve relationships with new customers, develop quality products with innovation, develop good and quality services, improve employee job satisfaction, increase employee skills, and knowledge employee knowledge. The eight strategic objectives are translated into 2 key financial performance indicator (KPI) perspectives, 3 internal business process KPIs, 4 customer KPI perspectives, and 5 KPI growth and learning perspectives, with targets for each KPI set based on discussions with Red&Blue cafe owners.

The Covid-19 pandemic has forced the government to enforce a physical distancing policy which is the basis for implementing learning from home. This is also something that must be applied to students at SLB Negeri 2 Bantul. The use of information technology that applies suddenly, not infrequently, makes educators and students surprised and limping in its implementation. However, the learning process must continue so that teachers at SLB Negeri 2 Bantul are challenged to create a learning media that students with special needs can understand. The limited knowledge of teachers at SLB Negeri 2 Bantul in making learning media causes the need for training and mentoring of learning media. One of the technological developments that we can use for making learning media is an application for video editing. This application can help to make videos to improve the quality and effectiveness of learning. Application users are expected to support the activities of SLB Negeri 2 Bantul to participate in competitions and promotions as routine activities that must be done every year. The two needs of these teachers are what make them collaborate to implement training programs based on the required classes. The implementation uses the Classical method and Practices using video recording applications and equipment. Community service will be carried out at SLB Negeri 2 Bantul to support improving skills in using software from basic to advanced levels. The result of this training is that the participants can make their own video creations so that they are eligible to be included in competitions and make video advertisements more professional.

This study aims to develop and determine the effectiveness of the "Rainbow Learning Box" learning media in fostering scientific literacy in early childhood. This media is designed as a simple, experiment-based science learning tool using colorful colors to help children understand the concepts of color, color mixing, and simple changes through play-and-learning activities. The study employed the Research and Development (R&D) method with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The study subjects consisted of 20 children aged 5–6 years at a pre-school (PAUD) institution. Data collection techniques included observation, interviews, documentation, and child development assessment sheets. The results showed that the use of the "Rainbow Learning Box" increased children's engagement in learning, curiosity, observation skills, and simple communication skills related to experimental results. Children appeared more active and enthusiastic during learning activities because the media was engaging, interactive, and suited to the learning characteristics of early childhood. Furthermore, teachers responded positively to the media's use, citing its ease of use, safety, and affordability. Therefore, the "Rainbow Learning Box" can be an alternative, innovative science learning media to optimally support the development of scientific literacy in early childhood. 

Virtual laboratories can provide real learning experiences through computer-aided simulations and activities. Virtual laboratory is rapidly developing its use in science learning because it is proven to provide significant benefits to the process and results of science learning during the pandemic. The limitations of laboratory facilities in genetics learning at the unkhair Biology Education Study program have encouraged the development of virtual practicum strategies and their use in genetic learning with modified free inquiry strategies on the topic of the structure and function of genetic material and reproduction of genetic material. The purpose of this study was to analyze the effectiveness of virtual laboratories based on student perceptions of the use of virtual laboratory applications and to describe and compare these perceptions with the use of laboratory reality and relevant previous research results. There are five aspects of perception surveyed, namely innovation, motivation, effectiveness, benefits, and presentation of practical procedures. This research method uses a quasi-experimental research design for the characteristics and effectiveness of using virtual laboratories and real laboratories in the Genetics course at the Biology Education Study Program, Khairun University, Ternate on the topic of DNA isolation, chromosomes and mitosis. The results of this study indicate that: the characteristics of Blended Learning practicum in the Genetics course in 4th semester students of Biology study program are: 1) instruction-based practicum; 2) practicum based on data collection and reporting of practicum results; 3) practicum based on proof of concept. The effectiveness of the implementation of genetics practicum in laboratory reality and virtual laboratories based on the perception of student responses is more likely to choose reality laboratories than virtual laboratories. The effectiveness of the implementation of genetic practicum based on the results of the practicum report is known to be not significantly different between the results of the practicum in reality and in the virtual laboratory.
