Judul: The Effect of Perceived Product Quality and Price on Consumer Satisfaction towards Local Fashion Brand
Abstrak: Tren fesyen di Indonesia terus berkembang dengan pesat dalam beberapa tahun terakhir. Hal ini telah menciptakan lingkungan yang semakin kompetitif, sehingga merek global maupun lokal terus bersaing untuk memenuhi kebutuhan masyarakat. Penelitian ini bertujuan untuk menganalisis pengaruh persepsi kualitas produk dan persepsi harga terhadap kepuasan konsumen produk fesyen lokal merek X. Desain penelitian ini adalah cross-sectional study dengan teknik purposive sampling. Pengumpulan data dilakukan secara offline dengan teknik accidental sampling menggunakan kuesioner kepada 182 responden. Data diolah dan dianalisis menggunakan Statistical Package for Social Science (SPSS) dan Partial Least Squares Structural Equation Modeling (PLS-SEM). Hasil menunjukkan tidak terdapat hubungan antara karakteristik responden dengan persepsi kualitas produk, persepsi harga, dan kepuasan konsumen. Persepsi kualitas produk berpengaruh positif signifikan terhadap persepsi harga dan kepuasan konsumen. Persepsi harga juga ditemukan berpengaruh positif signifikan terhadap kepuasan konsumen., Fashion trends in Indonesia have continued to grow rapidly in recent years. This has created an increasingly competitive environment, where local and global brands compete to meet people's needs. This research aims to analyze the effect of perceived product quality and price perception on consumer satisfaction towards local fashion product from brand X. The research design is a cross-sectional study with a purposive sampling technique. Data collection was conducted offline using a questionnaire administered to 182 respondents via an accidental sampling technique. The collected data were processed and analyzed using the Statistical Package for Social Science (SPSS) and Partial Least Squares Structural Equation Modeling (PLS-SEM). The results showed no significant relationship between respondents' characteristics and perceived product quality, price perception, and consumer satisfaction. Then, perceived product quality has a significant positive effect on price perception and consumer satisfaction. Price perception also has a significant positive effect on consumer satisfaction.

Judul: Sustainable Apparel Product Purchase Decisions on Indonesian Gen Z and Millennial Women Consumers
Abstrak: Fashion trends continue to change, sustainable and fast fashion brands continue to compete to provide diverse choices for consumers. This study aims to: (1) identify the characteristics of Indonesian Gen Z and millennial women consumers of sustainable apparel products, (2) analyze the influence of sustainable product attributes and marketing factors on sustainable apparel purchasing decisions (3) analyze the influence of individual and social factors on sustainable apparel purchasing decisions using the theory of planned behaviour. The sample in this study was 77 respondents selected by convenience sampling technique. Data analysis was carried out using the SEM-PLS method and descriptive analysis. The results showed that individual factor perceived behavioural control and social factor subjective norms had a positive and significant effect, sustainable product attributes, and marketing factors had a positive but not significant effect, and individual factors attitude had a negative but weak and insignificant effect on purchasing decisions for sustainable apparel products., Tren feysen terus berganti, brand sustainable dan fast fashion terus bersaing untuk memberikan pilihan yang beragam bagi konsumen. Penelitian ini bertujuan untuk: (1) mengidentifikasi karakteristik konsumen wanita produk pakaian berkelanjutan gen Z dan milenial Indonesia, (2) menganalisis pengaruh atribut dan pemasaran produk berkelanjutan terhadap keputusan pembelian pakaian berkelanjutan, dan (3) menganalisis pengaruh faktor individu dan sosial terhadap keputusan pembelian pakaian berkelanjutan menggunakan variabel theory of planned behavior. Sampel pada penelitian ini berjumlah 77 responden yang dipilih dengan teknik convenience sampling. Analisis data dilakukan menggunakan metode SEM-PLS dan analisis deskriptif. Hasil penelitian menunjukkan bahwa faktor individu pengendalian perilaku dan faktor sosial norma subjektif berpengaruh positif dan signifikan, faktor atribut dan pemasaran produk berkelanjutan berpengaruh positif namun tidak signifikan dan faktor individu sikap berpengaruh negatif namun lemah dan tidak signifikan terhadap pengambilan keputusan pembelian produk pakaian berkelanjutan.

Judul: Isolasi dan pemurnian bahan aktif dari mikroalga BTM 11 sebagai inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus is the cause of hepatitis C disease which has high virulence. Recent therapy using combination of ribavirin and alpha interferon has short efficiency < 80%. Thus, the discovery of new drug is needed. Antiviral drugs can be discovered through molecular target therapy by finding the inhibitor of RNA helicase that play role in viral replication. Inhibitor can be derived from chemical compound produced by microalgae. The aim of this research was to isolate the active compound from microalgae BTM 11 which had inhibitory activity against RNA helicase. Inhibitory activity was measured by releasing of phospate inorganic in colorimetric ATPase assay. Crude extract was fractionated using gel filtration chromatography with methanol in chloroform solvent. The result showed that Fraction 3 has the highest inhibitory activity which (81.205%). Phytochemical test of crude extract indicated positive flavonoids and coumarin. Thin layer chromatography (TLC) analysis with eluent chloroform: methanol gave 2 spots with Rf value of 0.8 and 0.37. Moreover, high performance liquid chromatography (HPLC) analysis showed absorption peak with the highest abundance at the retention time of 12.483 minute and 16.617 minute was 266 nm and 230 nm. According to these of phytochemical, TLC, and HPLC, inhibitor compound from BTM 11 belongs to flavonoids.
