Need To Evaluate

The circular economy (CE) can drive sustainability. For companies to select and implement circularity strategies, they need to evaluate and compare the performance of these strategies both in terms of progress towards CE but also based on their feasibility and business outcomes. However, evaluation methods for circularity strategies at the product level are lacking. Therefore, this research proposes a multi-criteria evaluation method of circularity strategies at the product level which can be used by business decision-makers to evaluate and compare the initial business of the company, transformative and future circularity strategies. This multi-criteria evaluation method aims to assist business decision-makers to identify a preferred strategy by linking together a wide variety of criteria, i.e., environmental, economic, social, legislative, technical, and business, as well as by proposing relevant indicators that take into consideration, where possible, the life cycle perspective. It also allows for flexibility so that criteria, sub-criteria, and weighing factors can be altered by the business decision-makers to fit the needs of their specific case or product. Two illustrative examples based on case companies are presented to verify and illustrate the proposed method.

This case study explores the strategic business opportunities, for Lane Crawford, an iconic luxury department store, to transition in a circular economy towards sustainability. A new experimentation framework was developed and conducted among cross departmental employees, during a Design Lab, with intention to co-create novel Circular Economy business concepts towards a new vision: the later was a reframe of the old system based on the principles of sustainability; to move beyond a linear operational model towards a circular economy that can contribute to a regenerative society. This work draws on both academic and professional experience and was conducted through professional practice. It was found that innovative co-created concepts, output from the Design Lab, can create radical change in a circular economy that is holistically beneficial and financially viable; looking forward to extract greater value a)Internal organization requires remodeling to transform towards a circular economy; b)Requirement for more horizonal teams across departments vs solely vertical; c)New language and relationships are required to be able to transition towards a circular economy; d)Some form of physical and virtual space requirements, for cross-disciplinary teams to come together to co-create; e)Ability to iterate, learn and evolve requires agency across the business

Instrumen penilaian merupakan bagian dari suatu proses penilaian dalam pembelajaran, apa yang hendak diukur dalam pembelajaran terkait dengan ketersediaan alat ukur yang dikembangkan. Tujuan penelitian yaitu untuk menganalisis validitas, reliabilitas, dan keefektifan instrumen. Penelitian ini menggunakan metode penelitian dan pengembangan (R & D). Tahapan pada R & D yaitu 1) analisis kebutuhan; 2) rancangan produk; 3) desain dan pengembangan; 4) validasi ahli; 5) revisi produk awal; 6) uji coba terbatas; 7) revisi produk; 8) uji coba diperluas; 9) revisi dan analisis hasil uji coba. Teknik analisis data menggunakan uji validitas instrumen menggunakan korelasi product moment, uji reliabilitas instrumen menggunakan koefisien kappa dari Cohen dan uji keefektifan menggunakan analisis Uji normalized-gain. Hasil penelitian menunjukkan bahwa hasil pretest nilainya 79 dan posttest nilainya 83 pada uji coba terbatas, sedangkan pada uji coba diperluas didapatkan hasil tidak jauh berbeda dengan uji coba terbatas yaitu pretest 0,3 dan posttest 0,4. Validitas instrumen sebesar 0,878 yang menunjukkan valid, reliabilitas instrumen sebesar 0.721 yang menunjukan ketegori baik dan keefektifan instrumen terdapat skor 0.3 yang memiliki tingkat efektivitas sedang. Hal ini menunjukkan bahwa instrumen penilaian praktik rias pengantin Jogja Paes Ageng baku, valid dan efektif digunakan untuk menilai penilaian praktik sesuai dengan kompetensi mata kuliah.Assessment instrument is part of the assessment process in the learning process. What is to be measured in the learning process is related to the availability of the assessment instrument. The aim of the current research is to analyze validity, reliability, and the instrument effectiveness. This current research employed R&D method. The steps of R&D method: 1) needs analysis, 2) product design, 3) design and development, 4) expert validation, 5) preliminary product revision, 6) limited testing, 7) product revision, 8) expanded testing, 9) revision and analysis of the testing product. The data analysis technique in the current research employed product moment correlation, kappa coefficient for instrument reliability and normalized-gain test analysis for the effectiveness of instrument. The results of the pretest was 79, the posttest was 83 on limited testing, while the expanded test showed not difference of limited testing 0.3 for pretest, 0.4 for the posttest. Validity of instrument was 0.878 which indicates the instrument developed is valid, reliability of practice instrument was 0.721 which indicates in the good category and effectiveness of instruments was 0.3 that have moderate levels of effectiveness. This suggests that the assessment instrument of bridal Jogja Paes Ageng practice is standardized, valid and effective.

Subject. The article considers the concept of circular economy, which has originated relatively recently in the academic literature, and is now increasingly recognized in many countries at the national level. In the European Union, the transition to circular economy is viewed as an opportunity to improve competitiveness of the European Union, protect businesses from resource shortages and fluctuating prices for raw materials and supplies, and a way to increase employment and innovation. Objectives. The aim of the study is to analyze the incentives developed by the European Commission for moving to circular economy, and to assess their effectiveness on the basis of statistical analysis. Methods. I employ general scientific methods of research. Results. The analysis of the EU Action Plan for the Circular Economy enabled to conclude that the results of the recent research in circular economy barriers, eco-innovation, technology and infrastructure were successfully integrated into the framework of this document. Understanding the root causes holding back the circular economy development and the balanced combination of economic and administrative incentives strengthened the Action Plan, and it contributed to the circular economy development in the EU. Conclusions. The measures to stimulate the development of the circular economy proposed in the European Action Plan can be viewed as a prototype for designing similar strategies in other countries, including Russia. Meanwhile, a more detailed analysis of barriers to the circular economy at the level of individual countries and regions is needed.
