Judul: Preferensi Konsumen Rumah Tangga dalam Pembelian Daging Sapi di Pasar Tradisional Kota Bogor
Abstrak: Kebutuhan daging sapi segar konsumen rumah tangga sebagian besar terpenuhi oleh pasar tradisional. Saat ini, jumlah pasar modern di Kota Bogor semakin bertambah dan konsumen mulai beralih untuk berbelanja di pasar modern. Akan tetapi, kondisi tersebut tidak mengurangi minat konsumen rumah tangga untuk membeli daging sapi di pasar tradisional. Tujuan penelitian ini adalah untuk mengkaji proses pengambilan keputusan konsumen, menganalisis preferensi konsumen, dan menganalisis atribut yang paling dipertimbangkan konsumen. Metode sampling yang digunakan adalah convenience sampling dengan 96 responden. Penelitian ini menggunakan metode deskriptif, analisis chi-square, dan analisis fishbein. Hasil penelitian menunjukkan bahwa terdapat perbedaan preferensi konsumen terhadap atribut yang ada pada daging sapi. Hasil penelitian juga menyebutkan bahwa sikap konsumen terhadap atribut yang paling dipertimbangkan dalam pembelian daging sapi di pasar tradisional adalah aroma daging sapi.

Judul: Sikap Konsumen terhadap Pembelian Daging Sapi di Pasar Tradisional Kabupaten Bogor
Abstrak: Konsumsi daging sapi di Kabupaten Bogor mengalami peningkatan setiap tahunnya. Pasar tradisional menjadi pilihan pertama konsumen dalam memeroleh daging sapi karena harga yang murah dan dekat dengan tempat tinggal. Namun, peningkatan ini diiringi oleh pertumbuhan jumlah pasar tradisional yang rendah. Disisi lain, kondisi tersebut tidak mengurangi minat konsumen untuk membeli daging sapi di pasar tradisional. Tujuan penelitian ini adalah menganalisis proses pengambilan keputusan konsumen dan sikap konsumen terhadap atribut daging sapi di pasar tradisional Kabupaten Bogor. Hasil penelitian menemukan bahwa proses keputusan pembelian daging sapi dimulai dari pengenalan kebutuhan, pencarian informasi, evaluasi alternatif, pembelian, dan yang terakhir perilaku pasca pembelian. Sikap konsumen terhadap kesembilan atribut daging sapi yang diteliti adalah positif dengan urutan atribut yang dipertimbangkan saat membeli daging sapi di pasar tradisional dimulai dari harga, warna, aroma, kandungan lemak, tekstur, bentuk promosi, warna lemak, golongan potongan, dan yang terakhir adalah atribut kandungan air., Beef consumption in Bogor Regency increases every year. Traditional markets are the first choice of consumers for obtaining beef due to their low prices and proximity. However, the number of traditional markets is experiencing low growth despite this increase. On the other hand, this condition does not reduce consumer interest in buying beef in traditional markets. The purpose of this study was to analyze the consumer decision-making process and consumer attitudes towards beef attributes in traditional markets in Bogor Regency. The results found that the beef purchase decision process starts with need recognition, information search, alternative evaluation, purchase, and finally post-purchase behavior. Consumer attitudes towards the nine beef attributes studied are positive, with the order of attributes considered when buying beef in traditional markets starting from price, color, aroma, fat content, texture, promotional form, fat color, cut class, and the last being the water content attribute.

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.
