Sustainable development is now the focus of researchers and organizations worldwide. Several concepts, such as reverse logistics (RLs) and closed-loop supply chains, have been introduced to encourage sustainability in supply chains. RLs refers to the set of activities needed by consumers to collect the product used for reuse, repair, remanufacturing, recycling, or disposal of the used product. There are various processes involved in RL, and one of them is collection systems. Collection refers to a company obtaining custody of specific items. We review the literature on RLs collection systems. A bibliometric analysis was conducted to provide better insight into the field and establish any trends. Firstly, we present the classification methods used in the field, based on available review papers. Secondly, we evaluate literature from several fields that are related to either the problem setting or the technical features. Different perspectives are presented and classified. This method facilitates the identification of manuscripts related to the reader’s specific interests. Throughout the literature review, trends in measuring the performance of collection systems are identified, and directions for future research are identified and presented.

The advancements in human lifestyle result in growth in daily demands of products, and accordingly, an increased rate of manufacturing. However, the resources on the planet Earth are limited, thus depleting day-by-day. More goods also contribute to more end-of-life (EOL) dumping or even before EOL in some cases. Therefore, an interest in remanufacturing has appeared, and it offers a solution that can solve or perhaps mitigate the risks of consuming more resources and increasing waste. Remanufacturing is a procedure of bringing used products to “like-new” functional status with a matching warranty. However, due to its relative novelty in terms of research field and industry, remanufacturing is poorly understood. People often mix it with other terms such as recycling, reconditioning, or repair. Therefore, in this research, the focus is on the remanufacturing systems’ definition, relevance, main phases, case studies, and solution methods proposed by various researchers. The word ‘remanufacturing’ is clearly described in this paper by differentiating it from alternative green manufacturing initiatives. Both qualitative and quantitative analysis of literature are performed. The quantitative analysis is conducted using a bibliometric method. For quantitative analysis, a systematic approach is utilized for research papers’ selection. The qualitative analysis has been carried out by discussing different aspects of remanufacturing and how the researchers are working on its different domains and phases. The review showed that researchers focused on some phases more as compared with others. Moreover, it is also revealed from the literature that the common solutions methods applied in this domain are optimization techniques. Future research directions are also identified and presented.

2)ABSTRAK Banyaknya penelitian-penelitian yang dilakukan dan aplikasi penerimaan peserta didik baru yang dihasilkan telah membantu proses PPDB pada institusi pendidikan yang menjadi objek penelitian, namun aplikasi tersebut belum tentu mampu berjalan dengan baik apabila dihadapkan pada kasus yang berbeda dan aplikasi tersebut akan menjadi tidak relevan apabila dipakai pada tingkat lain yang tidak memerlukan isian jurusan. Adanya sebuah layanan yang bisa memfasilitasi proses PPDB di segala tingkat pendidikan akan memudahkan institusi pendidikan yang belum memiliki fasilitas pendaftaran online dalam melaksanakan program PPDB tanpa perlu memikirkan proses development aplikasi yang memakan waktu dan biaya, mereka cukup mendaftar pada Aplikasi Layanan PPDB dan dapat membuka pendaftaran online pada saat itu juga. Namun, dalam rangka memfasilitasi proses bisnis yang berbeda-beda tersebut diperlukan logika yang kompleks, sehingga akan menghasilkan codebase yang besar. Maka dibutuhkanlah teknologi Docker untuk menyederhanakan pemaketan software sesuai dengan kebutuhan dan meletakkannya dalam kontainer terisolasi yang disebut dengan docker container, sehingga cocok diterapkan pada arsitektur microservices. Microservice yang menerapkan event-driven akan memungkinkan terjadinya pertukaran data antar service melalui Redis Stream sebagai message broker, dimana sebuah service yang ingin menggunakan data dari service lain dapat men-subscribe sebuah event, dan service lain yang ingin membagikan data akan mempublish sebuah event dalam sebuah topik tertentu. Berdasarkan masalah tersebut, penulis bermaksud untuk melakukan penelitian yang berjudul "Penerapan Event-Driven Microservices pada Aplikasi Layanan Penerimaan Peserta Didik Baru".
