Judul: Evaluasi Sistem Traceability pada Produksi Chewy Candy di PT Sweet Candy Indonesia Menggunakan FMECA (Failure Mode Effects and Criticality Analysis)
Abstrak: The low level of effectiveness and efficiency in traceability system implemented by an industry will conduce bad management of product quality assurance. Therefore, traceability system is necessary to be evaluated using FMECA (Failure Mode Effects and Criticality Analysis) method and arrangement of several mock recalls. Base on FMECA analysis, errors like no documentation of BTP batch number by the flavor room and production; no candy calculation in cut and wrap; damage or disappearance of checklist intermediate form (in transwrap); and no documentation of scrap separately by the incinerator are categorized in unacceptable area which have prefered priority in corrective action compared with errors of candy’s variety and batch number documentation in pulling to cut and wrap; damage or disappearance of non-document pulling form and checklist intermediate form (in copacking) that are categorized in undesirable area. The result of mock recall also show that the total average time consumption at PT Sweet Candy Indonesia is 310 minutes with 168,5 minutes dominated by production. Refer to those result, the effectiveness and efficiency level of traceability system at PT Sweet Candy Indonesia is still low which the maximum limit of 240 minutes as the operational standard is surpassed. In order to elevate the effectiveness and efficiency of traceability system at PT Sweet Candy Indonesia, implementation of kanban system in production can be the best solution in corrective action.

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.
