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: Model Minat dan Perilaku Konsumsi Produk Skincare Organik Menggunakan Extended Theory of Planned Behavior.
Abstrak: Minat konsumsi produk skincare di Indonesia terus meningkat termasuk skincare organik. Namun demikian, masih terdapat beberapa faktor yang menjadi kendala yang menghambat minat menggunakan produk skincare organik. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang memengaruhi minat dan perilaku konsumsi produk skincare organik menggunakan Extended Theory of Planned Behavior (ETPB). Penelitian ini melibatkan 200 responden pengguna skincare berusia 18-60 tahun yang dipilih secara purposive voluntary sampling technique. Structural Equation Model (SEM) digunakan sebagai basis analisis untuk menduga koefisien model kausalitas antar faktor. Hasil penelitian menunjukkan bahwa sikap konsumen dipengaruhi oleh kesadaran kesehatan dan kepedulian lingkungan. Sikap dan PBC memberikan pengaruh positif dan signifikan terhadap minat konsumsi. Namun, norma subjektif memiliki pengaruh negatif terhadap minat konsumsi. Minat konsumsi produk skincare organik memiliki pengaruh yang signifikan terhadap perilaku konsumsi produk skincare organik., Interest in consuming skincare products in Indonesia continues to increase, including organic skincare. However, there are still several factors that are still obstacles that hinder interest in using organic skincare products. This study aims to determine the factors that influence interest and consumption behavior of organic skincare products using the Extended Theory of Planned Behavior (ETPB). This study involved 200 skincare user respondents aged 18-60 years who were selected using a purposive voluntary sampling technique. The Structural Equation Model (SEM) is used as a basis for analysis to estimate the causality model coefficients between factors. The results showed that consumer attitudes were influenced by health awareness and environmental concern. Attitudes and PBC have a positive and significant impact on consumption intentions. However, subjective norms have a negative influence on consumption intention. The interest in consuming organic skincare products has a significant influence on the behavior of consuming organic skincare products.

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.
