Judul: Analisis Willingness To Pay Terhadap Produk Olahan Durian Pada Gerai Sop Duren Lodaya, Bogor
Abstrak: Dalam rangka mempertahankan keuntungan yang diperoleh dari hasil penjualan produk sop duren di gerai Sop Duren Lodaya pada periode inflasi, PT Lodaya Makmur Perkasa perlu menaikkan harga jual yang juga diiringi dengan peningkatan atribut produk dan penerapan strategi Segmenting, Targeting dan Positioning (STP) yang tepat. Penelitian ini dilakukan untuk mengidentifikasi karakteristik konsumen yang melakukan pembelian Sop Duren Lodaya menggunakan analisis deskriptif, menghitung nilai Willingness to Pay (WTP) konsumen dengan menggunakan metode Contingent Valuation Method, dan menganalisa faktor-faktor yang mempengaruhi kesediaan membayar konsumen menggunakan analisis regresi logistik. Hasil penelitian menunjukkan bahwa nilai rata-rata WTP untuk setiap jenis produk sop duren lebih tinggi dibandingkan dengan harga yang berlaku saat ini, dengan persentase peningkatan harga sebesar 14% hingga 29%. Faktor yang secara signifikan mempengaruhi kesediaan konsumen untuk membayar lebih mahal adalah penerimaan konsumen. Hasil dari penelitian ini dapat dijadikan pertimbangan dalam upaya penyesuaian harga dan penetapan strategi STP.

Judul: An analysis of custo,er satisfication and price sensitivity in sop durian lodaya coffee and resto
Abstrak: Bertambah banyaknya restoran yang berada di Kota Bogor membuat persaingan bisnis menjadi lebih besar, restoran harus mampu mempertahankan konsumennya agar mendapatkan keuntungan yang diharapkan. Studi perilaku konsumen merupakan metode yang digunakan untuk mengetahui psikologis konsumen sebagai objek dari pemasaran, sehingga dapat menjadi pertimbangan untuk kebijakan restoran. Penelitian ini bertujuan untuk mengkaji kepuasan konsumen dan sensitivitas harga di Sop Durian Lodaya Coffee and Resto di Jalan Bangbarung Raya No.69. Penelitian ini menghasilkan Customer Satisfication Index dengan nilai sebesar 72.54% yang menunjukkan bahwa atribut produk secara keseluruhan berada pada kriteria puas. Hasil dari Importance Performance Analysis menunjukkan bahwa atribut cita rasa yang lezat, keragaman rasa dan menu, kenyamanan dan kebersihan tempat, 100% durian asli memiliki kinerja yang sangat baik sehingga harus dipertahankan. Harga produk yang ditetapkan sangat penting untuk menggambarkan kualitas produk oleh karena itu harga yang digunakan sebaiknya berada pada Range of Acceptable Prices. Hasil analisis sensitivitas harga sop durian spesial porsi pas diperoleh Optimal Pricing Point Rp 19.000 dan Indifference Pricing Point Rp 18.000 sedangkan untuk porsi mabuk Optimal Pricing Point Rp 24.000 dan Indifference Pricing Point Rp 22.300., The increasing numbers of restaurants in Bogor City areas make the bussiness competition become larger, the restaurant must have capability to retain the customers for increasing profits. Study of customer behavior is a method to knowing customers psychological as the object of marketing, so it can be a consideration for restaurant policy. This research purpose to learn customer satisfication and price sensitivity in Sop Durian Lodaya Coffee and Resto at Jalan Bangbarung Raya No. 69. This research obtained value of Customer Satisfication Index is 72.54%, it indicates that overall the attribute product is satisfied. Results of Importance Performance Analysis indicates that attribute delicious taste, various menu and taste, comfortably and cleanliness of the place, 100% of the original durian composition, has excellent performance so it must be sustained. The product price is very important to describe quality of the product therefore the price used should be on Range of Acceptable Prices. Price sensitivity analysis resulted Sop Durian Special standard portion obtained Optimal Pricing Point Rp 19.000 and Indifference Pricing Point Rp 18.000 meanwhile for big portion Optimal Pricing Point Rp 24.200 and Indifference Pricing Point Rp 22.300.

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.
