Judul: Analisis faktor-faktor produksi yang memengaruhi output industri pengolahan dan pengawetan daging di Indonesia periode 1983-2008 (Pendekatan Total Factor Productivity
Abstrak: Industrial sector is the prime mover in economic development and drivers of economic growth. One of the industries is the food and beverage industry. Industrial food and beverage processing industry is one that contributes substantially in the formation of GDP. Developments in food and beverage industry is very important because one of the industries with the largest number of companies as well as the largest production value, which is processed in the food industry. Food is one of the basic needs that is very important in human life, one type of food is meat. Consumption patterns of carbohydrate-based to be protein-based and tendency to buy read- to-cook or ready-to-eat ingredients are driving consumption of processed and preserved meat increased in Indonesia. Good potential market in Indonesia encourage processing and preserving industrial of meat to always improve its production. This study aims to analyze the productivity of factors of production, Total Factor Productivity (TFP), and the factors that influence output and preserving meat processing industry in Indonesia.

Judul: Analisis faktor-faktor yang mempengaruhi output industri tepung terigu di Indonesia periode 1986 - 2003
Abstrak: Laju pertumbuhan sektor industri pada negara maju maupun negara berkembang relatif lebih cepat dibanding sektor pertaniannya. Sektor ini berangsur-angsur menggantikan peranan sektor tradisional (sektor pertanian) dalam menyerap tenaga kerja dan sumber pendapatan negara. Hal ini memberi indikasi bahwa perkembangan sektor industri sangat penting bagi pertumbuhan ekonomi secara nasional. Hingga saat ini, sektor industri telah memberikan kontribusi terbesar terhadap pertumbuhan ekonomi Indonesia, pada subsektor industri pengolahan, industri yang menyumbang paling besar terhadap PDB adalah industri makanan, minuman dan tembakau. Industri tersebut menyumbang lebih dari separuh jumlah PDB yang disumbangkan oleh subsektor industri pengolahan tanpa migas setiap tahunnya. Industri tepung terigu yang merupakan salah satu bagian dari industri makanan kini telah menjadi komoditi makanan tambahan yang cukup penting bagi masyarakat Indonesia. Industri tepung terigu memiliki keterkaitan (linkages) dengan industri nasional lainnya.

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.
