Judul: Penerapan Cost Volume Profit Analysis Sebagai Perencanaan Pencapaian Laba Dan Penjualan Pada PAPAPIA
Abstrak: The progress of the business world today is much developed, ranging from large scale sector and small scale. The increasing development of the business world affects the company increased competition in producing quality products and competitive prices. PAPAPIA are SMEs which is engaged in food especially food souvenirs typical of Bogor. During these SMEs PAPAPIA do not know the volume of sales that the company is at breakeven point. Breakeven point in January 2013 when sales reached 3,229 pieces, achieved in February 2013 when sales of 2,842 pieces. March's 2,681 pieces, 2,668 pieces of April, and in May 2,797 pieces. Greatest contribution margin for the month of January 2013 is cheese pia and smallest margin of durian pia, In February 2013-May 2013 the largest margin of is pia green beans and smallest margin is pia durian. Alternatif application of CVP is 5 percent raise prices, sales volume and fixed costs will remain fixed, the second 10 percent increase in sales volume, selling price of fixed.

Judul: Strategi Peningkatan Volume Penjualan Produk dan Pengurangan Biaya Operasional dalam Meningkatkan Laba UKM Mamanaia
Abstrak: SMEs Mamanaia tends to have fluctuation on operational cost and sales volume product, so that achievement profits of this business is unstable. The main goal of this research is giving suitable strategy CVP analysis to be applied for increasing profit. Trend, break even point, contribution margin, margin of safety, operating leverage, and CVP analysis are applied on this research. The results of this research are: (1) Operational cost structure on period September 2014-Februari 2015 consist of fixed cost with direct labour cost as the main component and variable cost with direct material cost as the main component; (2) The sales volume product is increasing 0.359% per day and the operational cost is increasing 0.23% per day; (3) SMEs Mamanaia have reached break even point condition on period September 2014-Februari 2015; (4) The value of operating leverage in this business is 1.79, that means if sales volume product increases 10%, the net income will increase 17.9%; (5) Alternative application of CVP are (a) decrease 0.25% chosen variable cost, sales volume product and selling price are fixed; (b)increase 0.4% sales volume product, chosen variable cost and selling price are fixed; (c)increase 0.4% sales volume product, decrease 0.25% chosen variable cost, and selling price is fixed.

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.
