Judul: Studi Kelayakan Usaha Restoran Sop Duren Addict Cibubur.
Abstrak: Restoran Sop Duren Addict merupakan salah satu restoran yang menyajikan durian sebagai menu utama. Sop Duren Addict Cibubur telah berjalan selama 2 tahun. Penelitian ini bertujuan untuk menganalisis kelayakan usaha Restoran Momomilk. Analisis kualitatif digunakan untuk menganalisis kelayakan aspek non finansial seperti aspek pasar, aspek teknis, aspek manajemen dan hukum, serta aspek sosial ekonomi dan lingkungan. Analisis kuantitatif digunakan untuk menganalisis kelayakan berdasarkan kriteria investasi. Aspek finansial menunjukkan NPV sebesar Rp1.046.669.632, Net B/C sebesar 11,95, IRR sebesar 247 persen, dan Payback Period selama 6 bulan 17 hari. Hasil analisis kelayakan ini menunjukkan bahwa Restoran Sop Duren Addict layak berdasarkan aspek pasar, aspek teknis, aspek manajemen, aspek sosial ekonomi dan lingkungan, serta aspek finansial. Namun usaha ini belum layak berdasarkan aspek hukum.

Judul: Analisis Kelayakan Usaha Restoran Momomilk di Taman Kencana Kota Bogor
Abstrak: Culinary business is one of the growing businesses in Bogor. Not only food, many restaurants also offer beverage products as their main menu. However, there are few restaurants that offer milk as their main product. Momomilk Restaurant is one of the restaurants that offers milk as its main product and has been running for the last 7 months. The objective of this study is to analyze the feasibility of Momomilk Restaurant. Qualitative analysis was used to analyze the feasibility based on non financial aspect such as market aspect, technical aspect, management and law aspect, and also social economic and environmental aspect. Quantitative analysis was used to analyze the feasibility based on investment criteria. Financial analysis showed that NPV was Rp63 220 511, Net B/C was 2.57, IRR was 47.35 percent, and payback period was 3 years 6 months 21 days. The result of this feasibility analysis showed that Momomilk Restaurant was feasible based on market aspect, technical aspect, management and aspect, social economic and environmental aspect, and also financial aspect. But, this business was not feasible based on law aspect.

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.
