Judul: Keputusan Pembelian Produk Makanan Berlabel Halal pada Layanan Delivery Online Selama Pandemi COVID-19 di Kota Bogor
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: Pengaruh Persepsi Label Halal terhadap Keputusan Pembelian Produk Makanan Beku oleh Konsumen Muslim Kabupaten Bogor
Abstrak: Perilaku konsumsi pangan masyarakat Indonesia yang berubah menjadi makanan beku mengakibatkan terjadinya peningkatan konsumsi makanan beku sebanyak 17 persen di tahun 2020. Sejak pandemi, makanan beku menjadi pilihan konsumsi paling populer bagi 55 persen masyarakat Indonesia sehingga penjualannya di tahun 2021 mencapai 2,02 miliar USD. Menurut LPPOM MUI, makanan beku memiliki titik kritis kehalalan sehingga berpotensi menjadi makanan haram kemudian masih terdapat produk makanan beku yang beredar di masyarakat belum memiliki sertifikat halal. Penelitian ini bertujuan untuk mengidentifikasi karakteristik dan persepsi konsumen muslim mengenai keberadaan label halal dalam produk makanan beku serta menganalisis faktor-faktor yang memengaruhi keputusan pembelian terhadap produk makanan beku oleh konsumen muslim Kabupaten Bogor. Penelitian ini dilakukan di Kabupaten Bogor dengan mengambil sampel sebanyak 100 responden. Metode yang digunakan dalam penelitian ini yaitu analisis deskriptif dan analisis Structural Equation Modeling-Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa harga, pendapatan, gaya hidup, dan kelompok acuan berpengaruh secara positif dan signifikan terhadap keputusan pembelian produk makanan beku., Consumer behavior changes have resulted in increased consumption of frozen food to 17 percent in 2020. Since pandemic, frozen food became the most popular consumption choice by 55 percent of the society with sales in 2021 reaching 2.02 billion USD. Based on LPPOM MUI, frozen food has critical points of halalness that can potentially become haram food and there are frozen foods in the public distribution without halal certificates. The research aims to identify the characteristics and perceptions of Muslim consumers regarding the existence of halal labels of frozen food products and analyze the factors that influence purchasing decisions for frozen food products by Muslim consumers in Bogor Regency. The research was conducted in Bogor Regency using sample of 100 respondents. The methods used are descriptive analysis and Structural Equation Modeling-Partial Least Square (SEM-PLS) analysis. The results of the research indicate that price, income, lifestyle, and reference groups have a positive and significant effect on purchasing decisions for frozen food products.

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.
