Judul: Model Minat Beli Produk Moisturizer Scarlett Menggunakan Structural Equation Modelling
Abstrak: Minat masyarakat Indonesia terhadap produk kecantikan dan perawatan tubuh meningkat setiap tahun. Scarlett merupakan merek perawatan kecantikan lokal yang memiliki akun media sosial Instagram dengan 5,6 juta pengikut (followers). Penelitian ini bertujuan mengetahui besarnya pengaruh antara variabel laten eksogen terhadap variabel minat beli pada produk moisturizer Scarlett. Structural Equation Modelling (SEM) digunakan sebagai basis analisis untuk menduga koefisien model kausalitas antar faktor. Hasil penelitian menunjukkan bahwa variabel laten attitude toward behavior, subjective norms, dan product berpengaruh positif dan signifikan terhadap variabel laten minat beli. Variabel laten promotion berpengaruh negatif dan signifikan terhadap minat beli. Sementara itu, variabel laten perceived behavioral control dan celebrity endorsement tidak berpengaruh signifikan terhadap minat beli.

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.
