Judul: Faktor-Faktor yang Memengaruhi Preferensi Remaja di Kota Bogor dalam Memilih Kafe dan Restoran Bersertifikat Halal.
Abstrak: Jumlah kafe dan restoran di Kota Bogor terus mengalami peningkatan dan salah satu konsumen potensialnya adalah remaja. Remaja merupakan konsumen kafe maupun restoran dan sudah masuk kategori mukallaf (wajib mematuhi perintah Allah SWT termasuk untuk mengonsumsi makanan halal). Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi preferensi remaja di Kota Bogor terhadap kafe dan restoran bersertifikat halal. Penelitian ini dilakukan dari November 2017 hingga Juli 2018 di SMA Negeri 1, SMA Negeri 3, SMA Negeri 4, SMA Negeri 6, dan SMA Negeri 7 dengan jumlah responden sebanyak 150 orang. Pengambilan sampel menggunakan teknik Purposive Sampling dengan analisis data menggunakan metode regresi logistik dan analisis deskriptif. Hasil analisis data menunjukkan bahwa faktor-faktor yang memengaruhi preferensi remaja terhadap kafe dan restoran bersertifikat halal adalah pengetahuan, religiusitas, dan lingkungan sosial.

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.
