Judul: Online Food Delivery Application Users Research on  The Use Of Digital Nudge to Shape Responsible Consumption
Abstrak: Layanan pesan antar makanan daring di Indonesia berkembang pesat, tetapi juga berdampak pada lingkungan dan konsumsi berlebih. Sebagai upaya untuk meminimalisir dampak negatif, aplikasi online food delivery telah menerapkan strategi nudging. Di Indonesia efektivitasnya masih belum dianalisis serta masih diperlukan analisis untuk menemukan strategi nudging yang efektif. Oleh karena itu, penelitian ini mengevaluasi efektivitas digital nudge pada generasi muda usia 18-29 tahun. Penelitian ini mengeksplorasi sikap dan perilaku terkait konsumsi yang bertanggung jawab serta penggunaan digital nudge dalam aplikasi, dengan menggunakan metode kuantitatif dan kualitatif. Hasilnya menunjukkan ketidaksesuaian antara sikap dan perilaku partisipan terkait konsumsi bertanggung jawab. Faktor-faktor seperti kurangnya kesadaran terhadap keberadaan fitur, biaya tambahan, penyajian informasi yang kurang menarik, kurangnya kerjasama serta pemahaman dari pihak restoran, dan kurangnya kepercayaan terhadap transparansi alokasi dana menjadi kendala dalam mencapai efektivitas yang diharapkan., Online food delivery in Indonesia is growing rapidly, despite its impact on the environment and overconsumption. To minimize negative impacts, online food delivery apps have implemented nudging strategies. In Indonesia, its effectiveness has not been analyzed and analysis is still needed to find an effective nudging strategy. Therefore, this study evaluates the effectiveness of digital nudge among young people aged 18-29 years. This research explores attitudes and behaviors related to responsible consumption and the use of digital nudging in apps, using quantitative and qualitative methods. The results showed a mismatch between participants' attitudes and behaviors regarding responsible consumption. Factors such as lack of awareness of the features, additional costs, unattractive presentation of information, lack of cooperation and understanding on the part of restaurants, and lack of trust in the transparency of fund allocation are obstacles to achieving the expected effectiveness.

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: 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.
