Judul: Consumer Patterns and Perceptions of Purchase Decisions and Consumer Loyalty in Milk Products in Jabodetabek
Abstrak: Produk minuman susu sudah banyak beredar di masyarakat dengan berbagai variasi, sehingga perlu memahami konsumen serta faktor yang mempengaruhi minat konsumen dalam melakukan pembelian, melalui atribut produknya. Penelitian ini bertujuan mengetahui pola konsumsi, persepsi konsumen dan loyalitas konsumen masyarakat terhadap produk minuman susu di wilayah Jabodetabek. Penelitian dilakukan dengan survei online yang terdiri dari tahapan yaitu studi literatur, penentuan metode pengambilan data, penentuan responden, penyusunan kuesioner, pengujian kuesioner, pengumpulan data, pengolahan data, dan pelaporan. Analisis data dilakukan dengan uji deskriptif, crosstab, Chi-square, dan uji Net Promoter Score dengan menggunakan software Microsoft Excel dan SPSS 25. Responden memiliki pola konsumsi tertinggi dengan frekuensi konsumsi sebanyak 1-2 kali seminggu pada jenis susu UHT berkemasan tetra pak pada brand Ultramilk. Pertimbangan keputusan pembelian dilihat dari faktor rasa, sertifikasi, dan kandungan gizi dengan memperhatikan kandungan protein, mineral, gula, vitamin, dan lemak. Beberapa dari profil responden seperti domisili, usia, jenis kelamin, pendidikan, pekerjaan, pendapat, dan pengeluaran memiliki hubungan yang signifikan terhadap beberapa atribut pola dan persepsi konsumen. Terdapat 5 dari 16 brand yang memiliki konsumen puas dan loyal karena memiliki Net Promoter Score yang bernilai positif., Milk products have circulated a lot in public with various variations, so it is necessary to understand consumers and the factors that influence consumer interest in making purchases, through product attributes. This study aims to determine consumption patterns, consumer perceptions and consumer loyalty to milk products in the Jabodetabek. The research was conducted using an online survey consisting of stages: literature study, determining data collection methods, determining respondents, preparing questionnaires, testing questionnaires, data collection, data processing, and reporting. Data analysis was carried out by descriptive, crosstab, Chi-square, and Net Promoter Score tests using Microsoft Excel and SPSS 25 software. Respondents had the highest consumption pattern with a consumption frequency of 1-2 times a week on UHT milk in tetra pak packaging for Ultramilk brands. Consideration of purchasing decisions is seen from the taste, certification, and nutritional content by paying attention to the content of protein, minerals, sugar, vitamins, and fat. Some of the respondents profiles such as domicile, age, gender, education, occupation, income, and expenditure have a significant relationship to some attributes of consumer patterns and perceptions. There are 5 out of 16 brands that have satisfied and loyal consumers because they have a positive Net Promoter Score.

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.
