Judul: Evaluasi Penerapan Total Productive Maintenance di PT Jakarana Tama.
Abstrak: Jakarana Tama. Dibimbing oleh PRAMONO D. FEWIDARTO. PT Jakarana Tama yang merupakan perusahaan yang bergerak dibidang manufaktur makanan, dengan salah satu produknya yaitu mie instan. Mesin merupakan salah satu komponen terpenting dalam sebuah produksi, untuk itu diperlukan keadaan mesin dalam keadaan prima. Total Productive Maintenance (TPM) adalah sebuah konsep untuk mengukur efektivitas lini produksi dengan melibatkan seluruh sumber daya manusia yang ada dan bertanggung jawab terhadap pemeliharaan fasilitas produksi. Penelitian ini bertujuan untuk mengkaji penerapan TPM, (2) Mengevaluasi penerapan TPM (3) Merekomendasikan peningkatan efektivitas penerapan TPM. Alat analisis yang digunakan yakni, analisis deskriptif, analisis overall efficiency effectiveness. Hasil penelitian menunjukan kegiatan TPM telah dilakukan dengan baik, dapat dilihat dari nilai OEE enam bulan terkahir yakni 85.20%. Budaya kerja 5S, 8 pilar TPM, dan kegiatan pemeliharaan juga telah dilaksanakan dengan baik. Tingkat pengawasan pada penerapan TPM masih cukup rendah.

Judul: Analisis Penerapan Total Productive Maintenance di PT XYZ
Abstrak: Total Productive Maintenance (TPM) is a maintenance concept that aims not only to improve productivity but also to improve morale and workers responsibilities to do they own job. The main objective of this research was to find the best strategy to improve the performance of TPM through the autonomous maintenance (AM) programs on the line sachet D as the line model of TPM implementation. Performance of TPM programs was measured based on measuring the value of Overall Equipment Effectiveness (OEE). OEE as measurement methods of the production machine effectiveness that involves measurement of the availability rate, performance rate, and quality rate. This method becomes a key factor in the productivity measurement of the production process. The best alternative strategy was determined by using of Analytical Hierarchy Process (AHP) model. Improvement was focused on reduced the cleaning and inspection time which is one of the highest downtime on the line sachet D. The result of this research will be able to identify the factors which influent productivity and to provide the best improvement strategy.

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.
