Abstrak: Salah satu jasa yang berkembang selama pandemi adalah layanan delivery online untuk makanan. Namun, tidak semua makanan yang tersedia pada layanan delivery memiliki logo halal. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang memengaruhi keputusan pembelian produk makanan berlabel halal pada layanan delivery online selama pandemi COVID-19 di Kota Bogor. Responden pada penelitian ini berjumlah 100 orang mewakili masyarakat Muslim Kota Bogor dan pengambilan data menggunakan kuesioner dengan skala likert. Analisis data menggunakan statistik deskriptif menunjukkan karakteristik masyarakat Muslim pada penelitian ini didominasi oleh responden dengan usia 18 – 24 tahun dengan 70 persen responden sudah memiliki pendapatan sendiri. Hasil regresi logistik menunujukkan variabel layanan penjual produk makanan, promosi, dan faktor sosial memiliki peluang yang signifikan terhadap keputusan pembelian produk makanan berlabel halal selama pandemi., One of the emerging services during the pandemic is food delivery online services. However, not all food available within the delivery service has halal logo. This research aims to determine the factors that influence the decision to purchase food products on delivery online services during the COVID-19 pandemic in Bogor. The sample of this study are 100 respondents representing Muslim Community in Bogor and the data is collected using questionnaire with Likert scale. The data was analyzed using descriptive statistics, showing that the characteristics of Muslim Community within this research are dominated by respondents aged 18-24 years old, with 70 of the respondents already having their own income. The results of logistic regression show that the variables of food product seller service, promotion, and social factors have significant opportunity towards the purchase decision for halal-labeled products during the pandemic.

Judul: Keputusan Pembelian Kosmetik Halal Oleh Muslimah Kota Bogor Selama Pandemi COVID-19
Abstrak: Indonesia sebagai negara mayoritas muslim terbesar di dunia merupakan pasar potensial bagi produk halal termasuk kosmetik. Namun, akibat pandemi COVID-19 kinerja industri kosmetik di Indonesia mengalami penurunan termasuk kosmetik halal. Penelitian ini bertujuan untuk mengetahui keputusan pembelian kosmetik halal oleh muslimah Kota Bogor selama masa pandemi. Sampel penelitian ini berjumlah 100 responden mewakili muslimah Kota Bogor dan pengambilan data menggunakan kuesioner dengan skala likert. Analisis data menggunakan statistik deskriptif dan regresi logistik. Berdasarkan hasil analisis statistik deskriptif karakteristik muslimah pada penelitian ini didominasi dengan usia 15 tahun hingga 25 tahun dan membeli kosmetik halal selama pandemi didominasi oleh responden pada usia 15 tahun – 25 tahun. Berdasarkan hasil analisis regresi logistik variabel promosi, tren dan halal awareness memiliki peluang yang signifikan terhadap keputusan pembelian kosmetik halal selama masa pandemi., Indonesia as the largest Muslim country in the world is a potential market for halal products, including cosmetics. However, due to the COVID-19 pandemic, the performance of the cosmetic industry in Indonesia has decreased, including halal cosmetics. This study aims to determine the decision to purchase halal cosmetics by Muslim women in Bogor City during the pandemic. The sample of this study amounted to 100 respondents representing Muslim women in the city of Bogor and data collection using a questionnaire with a Likert scale. Data analysis used descriptive statistics and logistic regression. Based on statistical analysis of the characteristics of Muslim women in this study, they were dominated by the age of 15 years to 25 years and halal cosmetics during the pandemic were dominated by respondents at the age of 15 years to 25 years. Based on the results of the logistic regression analysis of promotion variables, trends and awareness of halal have a significant opportunity to purchase halal cosmetics during the pandemic.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
