Abstract

Tujuan penelitian ini adalah untuk mengkomparasi Indeks Saham Syariah Indonesia (ISSI) dan Jakarta Islamic Index (JII) mengalami pergerakan harga saham yang cukup signifikan, dimana dapat diperbandingkan dalam dua periode yaitu pra vaksinasi dan pasca vaksinasi covid-19 di Indonesia. metode yang digunakan pada penelitian ini adalah penelitian kuantitatif. Populasi pada penelitian ini merupakan seluruh perusahaan/emiten yang terdaftar di Indeks Saham Syariah Indonesia (ISSI) dan Jakarta Islamic Index (JII) pada periode pra vaksinasi (Maret – Desember 2020) dan pasca vaksinasi (Januari – Oktober 2021) dengan jumlah 435 perusahaan (data emiten per 1 November 2021) untuk indeks saham ISSI, 30 perusahaan untuk indeks saham JII. Metode analisis data pada penelitian ini menggunakan aplikasi SPSS versi 23.00, dimana diawali dengan pengujian statistik deskriptif, uji normalitas data menggunakan skewness, dan uji hipotesis berupa uji paired sample t-test. Hasil penelitian menunjukkan bahwa terdapat perbedaan dari pergerakan indeks saham ISSI dan JII secara signifikan pada periode sebelum dan setelah masa vaksinasi Covid-19 di Indonesia. Hal ini dikarenakan periode sebelum diadakannya vaksinasi Covid-19 dianggap menjadi masa yang menunjukkan pergerakan indeks saham syariah paling rendah dikarenakan adanya kepanikan oleh para investor akibat adanya pandemi Covid-19. Kebanyakan investor mulai menjual banyak sahamnya di periode pra vaksinasi dan hal ini menjadikan harga saham syariah di BEI menurun. Namun pada masa pasca vaksinasi atau program vaksinasi covid-19 mulai digalakkan di Indonesia, pergerakan indeks saham syariah mulai mengalami peningkatan karena kepanikan investor akibat Covid-19 yang mulai berkurang.

Abstract

This study aims to examine how BPOM certification and halal certification influence consumer loyalty, with consumer trust acting as a mediating variable in the context of Mie Gacoan Kudus. A quantitative approach was employed by conducting a survey of 100 consumers who had purchased and consumed Mie Gacoan products. Data were collected using a Likert-scale questionnaire and analyzed through multiple linear regression with the assistance of SPSS. The findings indicate that BPOM certification and halal certification jointly contribute to strengthening consumer loyalty. When examined individually, both certifications show a positive effect on loyalty, although halal certification demonstrates a stronger influence than BPOM certification. The results further reveal that halal certification and consumer loyalty significantly shape consumer trust, whereas BPOM certification does not exhibit a meaningful effect on trust. These findings suggest that consumer trust is more strongly driven by halal assurance and repeated consumption experiences rather than by administrative aspects of food safety alone. This study highlights the importance of consumer trust in linking product certification and loyalty, particularly within the fast-food culinary industry in regions with a predominantly Muslim consumer base. The results are expected to provide practical insights for culinary business practitioners in developing trust-based strategies to sustain long-term consumer loyalty.
