Judul: Faktor-Faktor yang Memengaruhi Keputusan Mahasiswa dalam Membeli Produk Roti Berlabel Halal LPPOM MUI
Abstrak: Roti merupakan salah satu jenis makanan yang menggunakan bahan tambahan makanan sangat kompleks sehingga berpeluang besar masuknya bahan haram ke dalam produk roti. Bahan tambahan makanan yang diharamkan diantaranya margarin dan flavor dari lemak babi, cokelat dari pankreas babi, rhum dari alkohol (khamr), kuas dari kulit babi, dan lisetin pada terigu dari rambut manusia. Angka konsumsi produk roti di Indonesia berdasarkan data statistik Kementerian Pertanian cukup tinggi. Namun, dibandingkan dengan jumlah produsen roti yang belum berlabel halal, jumlah produsen roti yang berlabel halal masih tergolong sedikit. Hasil penelitian dengan metode regresi logistik menunjukkan terdapat empat variabel yang signifikan berpengaruh positif terhadap keputusan mahasiswa dalam membeli roti berlabel halal, diantaranya pengetahuan mengenai makanan halal, pengetahuan mengenai kehalalan roti, loyalitas terhadap label halal, dan pemasukan. Hasil studi menunjukkan pengetahuan mengenai makanan halal, citra LPPOM MUI, kesadaran akan kesehatan, aksesibilitas, dan loyalitas terhadap label halal responden berada pada kategori baik, sedangkan pengetahuan mengenai kehalalan roti responden berada pada kategori kurang baik

Judul: Faktor-faktor yang Memengaruhi Keputusan Pembelian Roti Merek Sari Roti (Studi Kasus Mahasiswa S1 Institut Pertanian Bogor)
Abstrak: Sari Roti is a bakery product which has many types and flavours produced by Nippon Indosari Corpindo. The purpose of this research is to describe and analyze the factors that influence purchasing decision of Sari Roti brand on BAU’s undergraduate students as consumers. The product’s attributes that are considered in validity and reliability test comprise price, variant, raw material quality, accesibility, product information, “halal” label, texture, taste, brand, expired date information, colour and its flavour. Meanwhile personal influences covered age, gender, pocket money monthly and the credit taken. Descriptive analysis, Fishbein Multi-attribute Attitude Model and Rank Spearman test from one hundred respondents shows that in general five stages of purchasing decision was passed and make expired date clarity into the most important consideration of attributes. Overall, students’s attitude toward Sari Roti brand is positive.

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.
