Judul: Online Transportation Application  Users Research on the Use of Digital Nudge to Shape Responsible Consumption
Abstrak: Riset Pengguna Aplikasi Transportasi Daring Terhadap Penggunaan Digital Nudge untuk Membentuk Konsumsi yang Bertanggung Jawab. Dibimbing oleh AUZI ASFARIAN dan ANNISA. Peningkatan penggunaan transportasi daring oleh generasi muda menghasilkan berbagai dampak. Untuk meminimalisir dampak negatif yang dihasilkan, aplikasi transportasi daring mulai mengimplementasikan strategi nudging, namun belum diketahui efektivitasnya di Indonesia. Sementara itu, penilaian ini diperlukan untuk menemukan strategi nudging yang efektif dalam menumbuhkan kebiasaan pemuda terhadap konsumsi yang bertanggung jawab. Untuk itu, pada penelitian ini dilakukan pengukuran efektivitas digital nudge pada aplikasi transportasi daring, khususnya di kalangan generasi muda berusia 18-29 tahun. Penelitian ini dilakukan secara kuantitatif dan kualitatif dengan berfokus pada sikap dan perilaku terkait konsumsi bertanggung jawab melalui digital nudges. Hasil penelitian menunjukkan adanya ketidaksesuaian antara sikap dan perilaku partisipan. Hal ini disebabkan oleh berbagai alasan, yaitu adanya biaya tambahan, kurangnya kesadaran akan keberadaan fitur, penyajian informasi yang kurang menarik, dan kekurangan kepercayaan terhadap transparansi alokasi dana dalam fitur tersebut., Online Transportation Application Users Research on the Use of Digital Nudge to Shape Responsible Consumption. Supervised by AUZI ASFARIAN dan ANNISA. The increasing use of ride-hailing by the younger generation has resulted in various impacts. To minimize the negative impacts, ride-hailing apps have begun to implement nudging strategies. However, its effectiveness in Indonesia is unknown. In fact, this assessment is needed to find nudging strategies that are effective in fostering youth habits towards responsible consumption. Therefore, this study measures the effectiveness of digital nudge in online transportation applications, especially among young people aged 18-29 years. This research was conducted quantitatively and qualitatively by focusing on attitudes and behaviors related to responsible consumption through digital nudges. The results showed a discrepancy between participants' attitudes and behaviors. This is due to various reasons, such as the presence of additional costs, lack of awareness of the existence of the feature, presentation of information that is less attractive, and lack of trust in the transparency of the allocation of funds.

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: Synthesis of Biphasic Calcium Phosphate Made of Eggshells Through A Hydrothermal Method
Abstrak: Biphasic Calcium Phosphate mixed of hydroxyapatite and tricalcium phosphate. A hydrothermal method of synthesizing by mixing CaO as calcium source and (NH4)2HPO4 as phosphate source with distilled water. CaO got from calcination process made of eggshells. All samples were synthesized using hydrothermal reactor then followed by sintering process. The molar ratio of Ca and P for all samples was 0.5 M : 0.3 M. Hydrothermal temperature and sintering temperature were variated they are 250 ºC, 300 ºC for hydrothermal and 800 ºC, 900 ºC, 1000 ºC for sintering, higher treatment temperature, tricalcium phosphate appears. Final results of synthesis were characterized by using X-ray Diffraction and Fourier Transform Infrared. X-ray Diffraction patterns was ecompared with database Join Committee on Powder Diffraction Standards and found tricalcium phosphate and hydoxyapatite.
