Judul: Analysis of Student Behaviour towards Beef  Consumption Before and During COVID-19 Pandemic
Abstrak: Daging sapi merupakan salah satu pangan yang permintaan meningkat setiap tahun. Konsumsi daging sapi akan meningkat seiring dengan pertumbuhan pendapatan nasional, namun kondisi tersebut tidak dapat dipastikan akibat pandemi COVID-19. Tujuan penelitian ini yaitu menganalisis perubahan perilaku konsumsi daging sapi dari masa sebelum pandemi dan selama pandemi COVID-19 berlangsung. Penelitian ini menggunakan data primer yang diperoleh melalui metode wawancara dengan google form. Kriteria responden merupakan mahasiswa di Indonesia. Hasil data yang diperoleh dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa perubahan perilaku mahasiswa terhadap konsumsi daging sapi relatif tidak berbeda dari sebelum pandemi hingga berlangsungnya pandemi COVID-19., Beef is one type of food that has an increasing demand level each year. Nationally, beef consumption will rise along with the growth of income, however, the current condition cannot be ascertained because of the COVID-19. The purpose of this research is to analyse the behavioural change of beef consumption before and during the COVID-19 Pandemic. This research use primary data which obtained through survey method using google from. The criteria of the respondent Indonesian collage student. The result from this research shown that beef consumption behaviour relatively did not change before until the pandemic COVID-19 continuous.

Judul: Analisis Minat Beli Konsumen pada Produk Daging Olahan dengan Sistem Keterlacakan QR (Quick Response) Code di Masa Pandemi COVID-19
Abstrak: Sejak terjadinya pandemi COVID-19, masyarakat menjadi lebih selektif terhadap bahan pangan yang dikonsumsi dan industri pengolahan daging dalam negeri mengalami penurunan permintaan. Salah satu solusi untuk produk daging olahan yang aman serta berkualitas adalah sistem keterlacakan QR Code. Penelitian ini bertujuan untuk menganalisis minat beli konsumen terhadap produk daging olahan dengan sistem keterlacakan QR Code semasa pandemi COVID-19 di Jakarta melalui integrasi model berdasarkan pendekatan Theory of Planned Behaviour (TPB), Technology Acceptance Model (TAM), variabel health consciousness, media exposure, serta habits. Responden yang diperoleh sebanyak 230 orang. Data yang digunakan dalam penelitian ini merupakan data primer dan data sekunder. Penelitian ini menggunakan metode analisis deskriptif dan SEM-PLS. Hasil dari penelitian ini adalah subjective norms dan attitude memengaruhi purchase intention secara langsung. Media exposure memengaruhi purchase intention melalui health consciousness, perceived information, dan attitude. Perceived information memengaruhi purchase intention melalui perceived usefulness. Perceived usefulness memengaruhi purchase intention melalui attitude. Perceived Ease of Use memengaruhi purchase intention melalui perceived usefulness dan attitude. Health Consciousness dan Habits tidak berpengaruh langsung dengan purchase intention, tetapi health consciousness berpengaruh baik dengan habits, habits berpengaruh baik dengan attitude yang berpengaruh baik dengan purchase intention., Since the COVID-19 pandemic, people become selective on food and the domestic meat processing industry has experienced a decline in demand. One of the solutions for safe processed meat products is the QR Code traceability system. This study aims to analyse consumer’s purchase intention towards traceable processed meat products with QR Code during the COVID-19 pandemic in Jakarta through model integration based on the approach of Theory of Planned Behavior (TPB), Technology Acceptance Model (TAM) and variables including health consciousness, media exposure, as well as habits. Total respondents obtained were 230 people. This research uses descriptive analysis method and SEM-PLS with primary data and secondary data. The results show that subjective norms and attitudes directly affect purchase intention. Media exposure affects purchase intention through health consciousness, perceived information, and attitude. Perceived information affects purchase intention through perceived usefulness. Perceived usefulness affects purchase intention through attitude. perceived ease of use affects purchase intention through perceived usefulness and attitude. health consciousness and habits do not have a direct effect on purchase intention, but health consciousness has a good effect on habits, habits have a good effect on attitude which has a good effect on purchase intention.

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.
