The use of mobile phone has increased at a surprisingly high rate over these two decades.  For many people, especially young generations, mobile phone has even become a primary need. As a consequence, the production of mobile phone has increased significantly and followed immediately by the disposal, as a result of its short life-cycle nature. Recently, there are substantial initiatives proposed in order to mitigate the effect of e-waste to the environment. Remanufacturing is one of recovery processes that could extend product’s useful life, and provide a circular life-cycle instead of linear. However, there are many factors that can affect the success of remanufacturing engagement, and specifically remanufacturability of a mobile phone. There are numerous considerations of remanufacturability with regards to the short life-cycle nature of mobile phone, and these factors can be qualitative or quantitative, with conflicting potentials, and some of them may be uncertain. In this study, we use Decision Making Trial and Evaluation Laboratory (DEMATEL) approach to identify the interrelationship among the factors, and analyze those results to identify the prominent factors. Furthermore, an influential-relation map is provided to support visualization for managerial implications.

Academic quality is defined as the equivalent to academic standards related to student learning outcomes, which consist of specific levels of knowledge, skills, and abilities achieved by students participating in a program. The achievement of academic standards is accommodated by implementing both internal and external quality assurance practices. Internal quality assurance refers to policies and practices used by the higher education institutions to monitor and improve the quality of their education, while external quality assurance refers to policies and practices set up by external parties to assure the quality of higher education institutions and programs. Petra Christian University has built and implemented its internal quality assurance since 2009 based on its unique quality culture. After its ten-year journey and the achievements that Petra Christian University has reached in 2019, the Industrial Revolution 4.0 and Society 5.0 are challenges ahead that Petra Christian University has to face.

Abstract:Remanufacturing has become more prominent as a recovery process to mitigate the massive disposal of short life-cycle product at its end-of-use. However, remanufactured product is often perceived to be inferior to new product, and it has lower value in consumer's willingness to pay. To increase the perceived quality of the remanufactured product, manufacturer offers a warranty, since one of the three roles possessed in warranty is being a signal to product reliability. This paper studies the pricing decisions and warranty level decision for new and remanufactured products in a closed-loop supply chain consists of a manufacturer and a retailer. The optimization modeling is performed under Stackelberg game with manufacturer as the leader. We found that higher expansion effectiveness coefficient would increase the supply chain profit. Also, there is an interval of demand's speed of change, where the total profit would be at its highest. The optimum warranty level can be achieved regardless the initial warranty level set at the beginning of retailer's optimization. Furthermore, the remanufactured product's wholesale and retail prices are influenced by the expansion effectiveness coefficient.

Remanufaktur adalah proses pemulihan barang bekas yang memberikan preservasi tertinggi terhadap nilai tambah produk originalnya, proses ini mentransformasikan barang bekas menjadi “seperti baru” dan seringkali dikembalikan ke pasar dengan garansi yang ekuivalen seperti produk baru. Praktik remanufaktur ini dapat memberikan dampak positif terhadap lingkungan karena dapat mengurangi limbah yang dibuang ke tempat pembuangan akhir. Namun remanufaktur juga memiliki banyak tantangan, tidak hanya dalam aspek teknikal dan operasional, tetapi juga pada aspek strategi dan desain. Makalah ini menyajikan pendekatan konseptual berdasarkan tinjauan literatur untuk menjawab tantangan remanufaktur dalam rantai pasok lingkaran tertutup, serta mengusulkan strategi dan desain implementasinya. Pendekatan yang digunakan adalah qualitative content analysis untuk mengidentifikasi berbagai konsep dan membagi dalam kategori yang sesuai. Hasil analisis menunjukkan bahwa implementasi remanufaktur dalam rantai pasok lingkaran tertutup dapat diterapkan dengan penentuan motif dan pendorong, dimensi keputusan remanufaktur, strategi implementasi remanufaktur, desain produk dan proses, serta desain jaringan.

Pandemi COVID-19 yang tengah merebak telah menciptakan keadaan darurat bagi kesehatan seluruh masyarak Pandemi COVID-19 yang tengah merebak telah menciptakan keadaan darurat bagi kesehatan seluruh masyarakat di Indonesia. Salah satu upaya yang dilakukan oleh pemerintah dalam meminimalisir penyebaran virus adalah dengan membuat kebijakan untuk mengubah pembelajaran dari konvensional (di sekolah) menjadi pembelajaran daring dengan bantuan internet di rumah masing-masing (School From Home). Banyak siswa dari keluarga kurang mampu akhirnya terpaksa mengalami kesulitan dalam mengikuti kelas pembelajaran online karena siswa tidak memiliki perangkat yang memadai untuk mengikuti kegiatan pembelajaran online. Penelitian ini bertujuan untuk mengetahui preferensi donator dalam mendonasikan smartphone bekas berdasarkan faktor kepercayaan, keamanan, kenyamanan, dan kualitas pelayanan. Sebanyak 216 data dikumpulkan melalui kuesioner dengan teknik Incidental Sampling, dan data diolah dengan statistik deskriptif dan tabulasi silang di IBM SPSS Statistics versi 26. Hasil penelitian menunjukkan bahwa sebanyak 170 responden bersedia mendonasikan smartphone bekasnya, sebanyak 78% di antaranya bersedia berdonasi, meskipun belum memiliki pengalaman dalam mendonasikan smartphone bekasnya dan hanya 8% dari responden yang memilih untuk tidak mendonasikan smartphone bekas mereka kembali.
