Judul: Analisis Persepsi Nilai Pelanggan Terhadap Loyalitas Pelanggan Susu Sapi pada J’rami Farm Kebon Pedes Bogor.
Abstrak: J’rami Farm merupakan usaha peternakan sapi perah turun temurun yang berdiri sejak tahun 1980an dengan produk utama susu sapi segar. Beberapa bulan terakhir J’rami Farm sempat beberapa kali mendapat komplain dari pelanggan. Untuk itu J’rami Farm ingin mengetahui bagaimana penilaian lainnya dari para pelanggan. Tujuan penelitian yaitu: (1) Menganalisis persepsi nilai pelanggan dan loyalitas pelanggan J’rami Farm; (2) Menganalisis pengaruh nilai pelanggan terhadap loyalitas pelanggan J’rami Farm. Penelitian ini menggunakan metode sensus. Instrumen penelitian adalah kuesioner dan dianalisis menggunakan metode regresi linier berganda. Hasil penelitian menunjukan persepsi nilai pelanggan terbesar adalah price/value for money sedangkan yang terendah adalah social value. Secara bersamaan nilai pelanggan berpengaruh terhadap pembentukan loyalitas pelanggan J’rami Farm. Secara parsial hanya price/value for money memberikan pengaruh pada loyalitas secara signifikan dan merupakan pemberi pengaruh terbesar diantara emotional value, social value dan quality/performance. Nilai pelanggan (customer value) yang dapat meningkatkan loyalitas adalah emotional value, quality/performance dan price/value for money.

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: 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.
