Tujuan dari penelitian ini adalah (1) mengidentifikasi faktor-faktor yang mempengaruhi keputusan konsumen dalam memilih Ravanaira, (2) mengembangkan karakteristik konsumen Ravanaira berdasarkan data geografis, demografis, dan perilaku untuk merancang strategi pemasaran, (3) merumuskan strategi pemasaran yang efektif dan inovatif bagi Ravanaira dalam rangka memperluas basis pelanggan. Analisis yang digunakan adalah analisis deskriptif dan klaster. Hasil analisis menghasilkan tiga klaster pelanggan berdasarkan faktor internal dan eksternal yang mempengaruhi keputusan konsumen. Penelitian ini merumuskan strategi pemasaran menggunakan bauran pemasaran 4C yang terdiri dari empat elemen: co-creation, currency, communal activation, dan conversation.., The introduction stage is a crucial stage for a business because at this stage the business is just entering the market and being introduced to customers. Ravanaira is one of the businesses that is in this stage and marketing strategy is key for Ravanaira to survive and enter the growth stage. This research aims to (1) identify the factors that influence consumers' decision to choose Ravanaira. (2) develop Ravanaira's customer profile based on geographic, demographi, and behavioral data to design a marketing strategy. (3) formulate effective and innovative marketing strategies for Ravanaira in order to increase number of customers. The results of the analysis produced three customer clusters based on internal and external factors that influence consumer decision-making. This research formulated a customer marketing strategy using the marketing mix 4C’s, which consists of four elements: co-creation, currency, communal activation, and conversation.

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.
