The development of the industry that is increasingly making businesses try to be competitive by increasing technical knowledge and improving systems both internally and externally. PDCA is a quality management system that is used as a continuous improve­ment tool that is widely used in the service and manufacturing sectors. PDCA activities consist of four steps namely Plan, Do, Check, and Action with repeated stages forming like a circle. PDCA is a continuous improvement tool that is widely used in the services and manufacturing sector. The cycle of PDCA begins with small to check possible effects on systems, but then eventually progresses to larger and more specific improvements. The results of the implementation PDCA method can be used to solve the problems of qualitative and quantitative data problems that have been widely applied in the service and manufacturing sectors for continuous improvement and as a work pattern in improving a process or system in an organization and increasing productivity. The method used in this research is the literature review research paper has been published in 2015-2020 that have consistently applied the PDCA cycle. The result of this literature review is to describe the relationship between thinking or gaps in theoretical and practical thinking about the application of the PDCA method and the successful implementation in the service and manufacturing sectors as a contribution to further research.

The Six Sigma approach has received a lot of attention in various industrial sectors from the manufacturing industry to the service industry. More specific knowledge about Six Sigma has grown rapidly. Much of the training and research on Six Sigma is carried out in various industries and university. This literature review related to Six Sigma purpose to provide an overview of Six Sigma implementation in the manufacturing industries.  The Six Sigma approach that has been introduced and implemented for a long time is DMAIC (Define, Measure, Analyze, Improve, and Control). This paper discusses the published literature related to Six Sigma ranging from 2015 to 2020. This paper involves the study review of 50 papers related to the implementation of Six Sigma of known database search including Elsevier, Science Direct, Emerald Insight and Google Scholars. This literature review contains results from a variety of different perspectives. The perspective includes the focus of the industry, the focus of the number of distribution by country, the focus of the year of publication and the focus of the number of publishers. In fact, this is useful for all types of manufacturing industries to find solutions to problems. The paper also provides advantages for researchers next to add to the literature.

Business competition is increasingly fierce, demanding that companies must provide the best products and services to customers. The quality of a product or service is an essential aspect for the continuity of a business, especially those attribute items that are directly felt by customers when purchasing or using a product. This study was aimed to analyze the quality of service to customers in a hospital-based on customer preferences. Customer assessment of each hospital quality indicator was performed through filling out questionnaires by inpatients, to determine the gap between the importance and performance levels. The analytical method used was Importance-Performance Analysis-IPA. As many as 25 quality indicators are identified from SERVQUAL. The quality dimension that becomes a priority for improved performance is related to Reliability, Assurance, and Empathy.

The development of digitalization has a positive impact to opportunity expand an innovation as a form of continuous improvement. One of the manufacturing companies, PT TCH, wants to implement Industry 4.0 innovation with the thought of integrating data and analytics supply chains. One of its applications is labeling error with a proportion value of 66% with an average error of 328 by creating a warning system for the Kanban system through the application of Quality Control Circle (QCC). The improvements made applying concepts Plan, Do, Check, and Action (PDCA) analysis by making improvements to the labeling system created from the PO database in marketing and creating a visualization of parts to help leverage product suitability. The results showed improvement with the decrease in cycle time from 265 seconds to 215 seconds and saving the cost IDR 70.48391 million / year. This research contributes theoretically in demonstrating the success of the application of QCC and in practical terms, it can provide a continuous increase in productivity and an actual decrease in process activities in the company.

The 360 degree feedback method is an assessment that can provide performance feedback from yourself, superiors, subordinates, and co-workers. The results of the implementation of this performance can be a monitoring and evaluation system for the employee and related employees to develop and set the target work and the determination of reward (reward). In this 360 degree feedback method found also an obstacle in which the emergence of internal assessment among employees. Keywords : performance appraisal, 360 degree feedback assessment method ABSTRAK Metode 360 degree feedback merupakan penilaian yang dapat memberikan umpan balik kinerja dari diri sendiri, atasan, bawahan, dan rekan kerja. Hasil dari penerapan kinerja ini dapat menjadi sistem monitoring dan evaluasi bagi pihak kepegawaian dan pegawai terkait untuk mengembangkan dan menetapakan target kerja dan penentuan penghargaan (reward). Pada metode 360 degree feedback ini ditemukan juga penghambat dimana akan munculnya penilaian internal antar pegawai. Kata Kunci : penilaian kinerja, metode penilaian 360 degree feedback

This paper aims to explore benchmarking in various industries beyond Indonesia to find the gap between each industry and what makes it different from Indonesia. Benchmarking is recognized as an essential instrument for continuous quality enhancement. In this paper, the author has reviewed 60 articles distributed from 2015 to 2020 in a variety of journal research and journal review. Systematic literature reviews are the approaches used in this study since a precise, consistent, and clear methodology, with a variety of steps, guarantees sufficient rigor and clarity in the literature review process. Authors have a review in multi-perspective to help researchers, academics, and practitioners more deeply understand and take a closer look at the growth, development, and applicability of this technique. Authors have classification the various paper-based on goals and scope of achievement from benchmarking applicable. In Addition, this paper also needs to find a better solution from each gap of benchmarking in the pandemic situation with the industry 4.0 approach

The development of science and technology and the factors of the ASEAN economic community (MEA) which are supported by increasing industry 4.0, the government gives important responsibilities for universities to be able to produce human resources that can compete in that era. This affects universities to continue to improve in terms of the quality of learning, service quality, to provide satisfaction to students which has an influence on the productivity of higher education. In this regard, research was conducted on 120 samples of student respondents (active students, and alumni) who were used to provide information by distributing questionnaires processed by Structural Equation Modeling (SEM) - Partial Least Square (PLS). Based on the results of the analysis and discussion it can be concluded that service quality has a positive effect on student satisfaction and positively influences the productivity of higher education.
