Judul: Analisis Biaya Pemanenan Untuk Menentukan Upah Minimum
Abstrak: Minimum wage is the lowest wage that will be used as a standard by the employer to determine the real wages of workers who work in the company. The minimum wage aims to enable a worker is able to meet the minimum needs of his own life. This study aims to calculate the production cost and the results obtained workers labor in logging activities in order to determine the minimum wage of workers as well as being an effort to increase labor productivity to achieve the welfare of workers. This research was carried out questionnaires to timber cutting workers at RPH Maribaya, BKPH Parung Panjang, KPH Bogor 36 people (6 teams) and discussions with the foreman in the region as well as the questionnaire to forest communities Desa Tapos and Barengkok number 36 adults who are married . The data obtained is a form of description of prevailing wage in the region and analyzed the suitability to the needs of the community life. The results showed that the wages earned by workers felling does not comply with the minimum wage set by the government, but the reward has been able to sustain their community.

Judul: Analisis dampak kebijakan upah minimum terhadap tingkat kemiskinan Indonesia
Abstrak: Indonesia merupakan negara dengan kekayaan alam dan budaya yang melimpah, namun tingkat kemiskinan di Indonesia masih saja tinggi, meskipun setiap tahunnya tingkat kemiskinan Indonesia mengalami penurunan. Salah satu kebijakan di bidang ketenagakerjaan untuk mengentaskan masalah kemiskinan adalah kebijakan upah minimum. Kebijakan Upah Minimum Provinsi dibuat dengan tujuan meningkatkan kesejahteraan para pekerja sehingga merupakan salah satu kebijakan yang akhirnya diharapkan dapat mengurangi tingkat kemiskinan di Indonesia. Fakta menunjukkan bahwa tingkat kemiskinan di Indonesia masih saja tinggi meskipun kebijakan UMP tersebut telah diterapkan. Penelitian ini bertujuan untuk melihat dampak kebijakan Upah Minimum Provinsi terhadap tingkat kemiskinan Indonesia periode tahun 2007-2012. Metode yang digunakan adalah metode analisis data panel dengan model estimasi terbaik yaitu fixed effect model (FEM). Hasil analisis regresi menunjukkan bahwa variabel Produk Domestik Regional Bruto (PDRB), Upah Minimum Provinsi (UMP), dan tingkat pendidikan memiliki pengaruh yang signifikan terhadap tingkat kemiskinan. Upah Minimum Provinsi (UMP) memiliki pengaruh yang negatif dan signifikan terhadap tingkat kemiskinan di Indonesia selama periode penelitian.

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.
