Judul: "Business Model Canvas (BMC) Base on Consumer Value Perceptions and Preferences for Frozen Food - Packaged Meatballs in Bandung City Markets"
Abstrak: Frozen food products have spread widely on the market, either in the form of food ingredients (frozen harvest) or food that has been pre-processed (then frozen). Frozen food is the choice of many people who don't have much free time to cook food. There are already many businesses around frozen food in Indonesia, both in production, distribution and retail sales. One type of frozen food is packaged meatballs. Packaged meatballs are a type of food that is quite popular in Indonesia. There is still a big opportunity to run a frozen food business in Indonesia because the Indonesian population is very high and increases every year. The impact of the Covid-19 pandemic has also affected people's lifestyles, from BPS data it is recorded that the highest online sales were in food and beverages which rose sharply by 1070% from sales in January 2020. The products most purchased during the pandemic were 55 percent of foods such as frozen food. or ready to cook (ready to cook). Currently, competition between manufacturers is increasingly competitive, as indicated by the increasing number of companies offering similar products. To win the competition, companies need to know consumer value perceptions, preferences and behavior in purchasing decisions as a basis for determining marketing strategies. Consumer value perceptions, preferences and behavior need to be analyzed, because they cannot be controlled directly by the company. Information on consumer behavior is obtained from research results. This research on frozen food - packaged meatballs was obtained from a market survey by collecting questionnaire data from 100 respondents (housewives, students and workers) by filling out questionnaires which were distributed offline in traditional markets in the city of Bandung and then analyzed using descriptive and statistically analyzing them. The research results show that perceived value has a significant effect on the decision to buy packaged meatballs, while preference does not have a significant effect on the buying decision. By using BMC, there are managerial implications that CV continues to carry out, improve and change. Semar who want semar meatballs to have attributes or characteristics that are tastier, tastier, cheaper, higher quality and better. Higher quality attributes and characteristics are related to the basic ingredients, ingredients, texture and ease of obtaining the product. Cheaper characteristics relate to the price of the product. Better characteristics relate to product quality dimensions. In this case, most manufacturers provide various types of products based on the quality of the products offered to be accepted by consumers, Produk makanan beku sudah banyak menyebar di pasar baik dalam bentuk bahan makanan (hasil panen dibekukan) atau makanan yang sudah diolah terlebih dahulu (kemudian dibekukan). Frozen food atau makanan beku menjadi pilihan banyak orang yang tidak punya waktu luang yang banyak untuk memasak makanan. Sudah banyak bisnis seputar frozen food di Indonesia baik itu dalam produksi, distribusi, maupun penjualan eceran. Salah satu macam dari frozen food adalah bakso kemasan. Bakso kemasan merupakan jenis makanan yang cukup populer di Indonesia. Peluang untuk berbisnis makanan beku masih berpeluang besar di Indonesia karena tingkat populasi penduduk Indonesia yang sangat tinggi dan setiap tahunnya bertambah. Dampak pandemi

Judul: Factors That Affect Muslim  Household Behavior in Purchasing Halal Labelled Frozen Food
Abstrak: Selama pandemi, 64% masyarakat Indonesia lebih memilih membeli produk UMKM melalui e-commerce dan produk yang paling banyak dibeli hingga 55% adalah makanan, terutama frozen food. Permintaan makanan beku pada tahun 2020 meningkat secara signifikan sebesar 17% dibandingkan dengan tahun 2019. Di sisi lain, produk frozen food memiliki risiko tinggi dan memerlukan perlakuan khusus untuk mempertahankan status kehalalannya. Penelitian ini bertujuan untuk mengidentifikasi karakteristik konsumen dan menganalisis faktor-faktor yang memengaruhi minat beli dan perilaku konsumen dalam membeli frozen food berlabel halal. Penelitian ini dilakukan di Kota Jakarta Selatan dengan mengambil sampel sebanyak 100 responden ibu rumah tangga. Metode yang digunakan adalah analisis deskriptif dan analisis Structural Equation Modeling-Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa norma subjektif, persepsi kontrol perilaku, dan religiusitas berpengaruh signifikan dan positf terhadap minat beli frozen food berlabel halal. Minat beli berpengaruh secara positif dan signifikan terhadap perilaku pembelian frozen food berlabel halal, lalu norma subjektif, persepsi kontrol perilaku, dan religiusitas secara tidak langsung berpengaruh secara positif dan signifikan terhadap perilaku pembelian frozen food berlabel halal. Adapun, sikap dan kesadaran halal berpengaruh positif, namun tidak signifikan terhadap minat beli frozen food berlabel halal. Kata Kunci: perilaku. frozen food, rumah tangga Muslim, SEM-PLS

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
