Lean management has generated new approaches to reduce non-value-adding activities in different sectors of the economy, including in higher education systems. Lean principles in higher education institutions (HEIs) contribute positively to sustainability performance. The current study aims to: (a) assess waste in HEIs based on lean principles and even their potential effect on sustainability; (b) establish the relationship among wastes; (c) develop a structural model using Interpretative Structural Modeling (ISM); (d) carry out the Matrice d’impacts Croisés Multiplication Appliqué Àun Classement (MICMAC) analysis. In Phase 1 of this study, the identification of waste modes in HEIs was established. In Phase 2, risk assessment of each waste mode was conducted using the waste-Failure Mode and Effect Analysis (w-FMEA) technique. In Phase 3, ISM-MICMAC was used to identify relationships among critical waste modes. The results showed that eighteen waste modes were identified as critical in HEIs—with six waste modes being autonomous determinants; four were dependent determinants, four were linkage determinants, and four were driver determinants. This study is expected to help academicians and practitioners understand HEI’s waste types by listing the critical wastes, mapping their interrelationship, identifying the driving power and dependence, and proposing mitigation actions. It will also contribute to the growing body of literature highlighting the waste in HEIs.
Lean is a philosophy that is seen as a solution to resolve the problem of efficiency in various industries. It can be used to eliminate all forms of waste in the workplace. The implementation of lean is not only applied in manufacturing but is very important to be applied in other fields, such as in Higher Education Institution. Studies on the topic of lean in the workplace have been carried out, but most of the study has been conducted within a manufacturing context. This study aims to determine the type of waste that is most important to be eliminated first by using the Waste Assessment Model and find the root of the waste problem. This study developed the relationship between waste and find out the effect of waste on each other in Higher Education Institution that focused on teaching and learning process. The steps of this study consist of three-step, such as waste identification, waste assessment, and root cause analysis. From data collection show that there are 46 forms of waste in the teaching and learning process. The results of the Waste Relationship Matrix showed three types of waste must be removed first, namely overproduction, defects, and non-utilized talents. 5-Why’s is used to find out the root causes of waste which is the most important to be eliminated first in the teaching and learning process.
Most of the time, students need to do selfstudy in order to understand the physics material completely. Knowledge about physical quantities and measurement is a pre-requisite for experiment-based physics class. Thus, students need to master it well. In this project, we develop supporting multimedia in the form of android app to assist students in doing selfstudy on topics regarding the physical quantities and measurement. Android app platform is chosen because it can provide interactive text, illustration and video. It is also popular among students, and it can be used easily by students everywhere and every time. The android app contains explanations, discussions, video demonstrations, exercises and quizzes. Field testing has been conducted to evaluate the effectivity of the android app to improve the students’ conceptual understanding. According to field testing, the use of the android app in self-study is potential to enhance students’ conceptual understanding of physical quantities and measurement principles.
ABSTRAKFisika adalah ilmu yang sangat erat dengan kehidupan sehari-hari dan menjadi tonggak perkembangan teknologi. Oleh sebab itu, mata pelajaran fisika diberikan pada siswa-siswa Sekolah Menengah Atas (SMA). Pembelajaran Fisika harusnya menekankan pada pengalaman langsung untuk mengembangkan kompetensi agar siswa mampu memahami fenomena alam. Hal ini akan membantu siswa untuk memperoleh pemahaman yang lebih mendalam. Akan tetapi, banyak sekolah-sekolah di Indonesia tidak memiliki peralatan yang cukup memadai untuk menunjang pembelajaran eksperimen, termasuk beberapa SMA di daerah Surabaya dan sekitarnya. Program Studi Pendidikan Fisika sebagai institusi yang mencetak calon guru-guru fisika perlu memberikan andil dalam mengatasi keterbatasan yang dimiliki oleh SMA-SMA di Surabaya dan sekitarnya. Program Studi Pendidikan Fisika memiliki peralatan dan sumber daya manusia yang cukup memadahi sehingga memungkinkan untuk mengadakan program pengabdian masyarakat berupa Pendampingan Eksperimen Fisika untuk Siswa-Siswa SMA. Program ini telah terlaksana sejak September 2018 hingga April 2019 melibatkan 14 sekolah mitra dengan jumlah siswa yang berpartisipasi sebanyak 1259 siswa. Kegiatan ini mendapatkan respon yang baik dari pihak sekolah, guru fisika, dan para siswa. Melalui kegiatan ini, keterbatasan peralatan eksperimen di sekolah cukup teratasi. Para siswa juga antusias sebab dengan kegiatan eksperimen pembelajaran fisika menjadi lebih menarik.Kata Kunci: eksperimen fisika; pengabdian kepada masyarakat; sekolah menengah atas. ABSTRACTPhysics is closely related to our daily life and becomes a fundamental subject for technology development. That is why physics is given to high school students. The physics learning process should emphasize direct experience to guide students in understanding phenomena in nature. The direct experiment will stimulate students to develop their in-depth knowledge. However, most schools in Indonesia, including in Surabaya, do not have adequate experiment apparatus to support that physics learning activity with experiments. Department of Physics Education, as an institute that educates pre-service physics teachers, should contribute to solving the limitation of some senior high schools in Surabaya. Department of Physics Education in Widya Mandala Catholic University has sufficient experiment facilities and human resources to conduct a community service program in the form of Physics Experiment Assistance for High School Students. The program has been conducted from September 2018 until April 2019. There are 14 schools attendinng this program, with 1259 students involved. This program gains positive responses from school principals, physics teachers, and students. Through this program, the limitation of several high schools in providing experiment facilities can be partially solved. Students who involve in this program are enthusiastic because, through experiments, physics learning activity becomes more interesting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
