Judul: Redesain Digital Nudge pada Aplikasi Ride Hailing untuk Meningkatkan Konsumsi yang Bertanggung Jawab di Kalangan Pemuda
Abstrak: Konsumsi yang bertanggung jawab menjadi tujuan penting untuk menjaga ketahanan dan keberlanjutan. Salah satu kebutuhan konsumsi utama saat ini adalah transportasi online atau ride hailing. Tetapi perilaku konsumsi yang bertanggung jawab pada sektor ride hailing di Indonesia masih sangat minim. Perilaku masyarakat pada lingkungan digital dapat diarahkan dengan digital nudge. Penelitian sebelumnya menemukan bahwa digital nudge terkait konsumsi yang bertanggung jawab pada aplikasi ride hailing belum digunakan oleh generasi muda. Penelitian ini bertujuan merancang ulang teknik nudging terkait konsumsi yang bertanggung jawab serta menguji prototipe. Penelitian ini dilaksanakan dalam 5 tahapan yakni perumusan research-based persona, pembangkitan ide redesain menggunakan SCAMPER, pembuatan prototipe, uji kegunaan, dan wawancara. Prototipe redesain berhasil meningkatkan penggunaan fitur terkait konsumsi yang betanggung jawab sebesar 26,7%., Responsible consumption is an important goal to maintain resilience and sustainability. One of the main consumption needs today is online transportation or ride hailing. However, responsible consumption behavior in the ride hailing sector in Indonesia is still very minimal. People's behavior in the digital environment can be directed with digital nudge. Previous research found that digital nudges related to responsible consumption on ride hailing applications have not been used by the younger generation. This research aims to redesign nudging techniques related to responsible consumption, as well as testing prototypes. This research was carried out in 5 stages, namely formulating research-based personas, generating redesign ideas using SCAMPER, making prototypes, usability testing, and interviews. The redesign prototype succeeded in increasing the use of features related to responsible consumption by 26.7%.

Judul: Redesign of digital nudges in e-commerce applications to promote responsible consumption
Abstrak: Peningkatan konsumsi bertanggung jawab telah mempengaruhi berbagai aspek layanan teknologi, khususnya dalam e-commerce. Pertumbuhan pesat platform e-commerce, terutama Tokopedia, telah mendorong perkembangan ekonomi, namun juga membawa dampak negatif yang tak terhindarkan, terutama terkait keberlanjutan lingkungan dan sosial. Konsep konsumsi bertanggung jawab menekankan pada pengurangan penggunaan sumber daya alam, bahan berbahaya, dan limbah untuk menjamin masa depan yang berkelanjutan. Penelitian ini bertujuan untuk merancang digital nudge yang efektif di platform e-commerce Tokopedia untuk mendorong kebiasaan konsumsi bertanggung jawab serta menguji rancangan prototipe. Penelitian dilakukan dalam beberapa tahapan yakni pembangkitan ide menggunakan SCAMPER, prototyping, uji kebergunaan, dan wawancara. Prototipe redesain berhasil meningkatkan penggunaan fitur responsible consumption berupa fitur donasi dari 40% menjadi 67%., The increase in responsible consumption has impacted various aspects of technology services, particularly in e-commerce. The rapid growth of e-commerce platforms, especially Tokopedia, has driven economic development but also brought unavoidable negative effects, particularly related to environmental and social sustainability. The concept of responsible consumption emphasizes reducing the use of natural resources, hazardous materials, and waste to ensure a sustainable future. This research aims to design an effective digital nudge on the Tokopedia e-commerce platform to encourage responsible consumption habits and test the prototype design. The study was conducted in several stages, including generating ideas using SCAMPER, prototyping, usability testing, and interviews. The redesigned prototype successfully increased the use of responsible consumption features, such as donation features, from 40% to 67%.

Judul: Hydrothermal Synthesis of Biphasic Calcium Posphate
Abstrak: Biphasio calsium phosphate (BCP), which was a mixture of hydroxypatite (HA) and tricalcium phosphate (TCP), was synthesized by hydrothermal method followed by sintering process. Hydroxyapatite was produced by using natural calcium source CaO from hen's eggshell and (NH4)2HPO4 as phosphate souce, other hydroxyapatite sample was produce by using synthetic calcium source Ca(OH) and H3PO4 as phosphate source.
