Judul: Root Causes Analysis of  Defects and Its Improvement in Meat Roll Production Process at CV. Fiva Food
Abstrak: Konsumsi daging di Indonesia telah mengalami pertumbuhan mencapai 10% per tahun dari tahun 2015 hingga 2019. CV. Fiva Food & Meat Supply merupakan salah satu perusahaan pengolahan daging di Indonesia yang menghasilkan berbagai produk daging olahan. Rolade daging merupakan produk unggulan dari Perusahaan ini. Namun demikian, proses produksi rolade daging ini masih menghasilkan produk cacat hingga 16% dari total berat produksi. Perkerjaan magang ini bertujuan untuk menganalisis faktor penyebab terjadinya cacat produksi rolade daging sehingga dapat merekomendasikan proses perbaikannya. Metode yang digunakan dalam perkerjaan magang ini mengikuti tahapan pendefinisian, pengukuran, analisis, perbaikan, dan pengendalian cacat. Proses produksi rolade melibatkan tahapan penggilingan, pengadukan, penggulungan, pengukusan, pendinginan, pengirisan, dan pengemasan. Proses produksi rolade menghasilkan 4 jenis cacat produk yaitu terjadinya berlubang, terkelupas, terpecah, dan yang terbanyak adalah cacat sisi samping. Berdasarkan pengamatan dan diskusi, upaya perbaikan dilakukan dengan cara menekan ujung sisi samping selama proses pemasakan. Perbaikan ini berhasil mengurangi tingkat produk cacat menjadi 10,67%, namun masih belum mencapai target industr, yaitu sebesar 10%.

Judul: Evaluation of Burger Bread Production Process in Order to Reduce Product Defects at PT Indo Primafood Abadi
Abstrak: Roti burger Gaspol merupakan salah satu produk utama di PT Indo Primafood Abadi. Mutu produk menjadi indikator yang sangat penting bagi perusahaan supaya dapat bersaing di pasar. Untuk mempertahankan mutu produk roti yang sesuai dengan spesifikasi dan regulasi perusahaan, diperlukan sistem produksi yang terstandarisasi dengan baik. Mutu produk yang buruk dapat menyebabkan penurunan mutu produk dan profitabilitas perusahaan. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis jenis kerusakan yang terjadi beserta faktor penyebabnya dan mengevaluasi sistem proses produksi melalui audit internal perusahaan. Data kerusakan produk diperoleh melalui observasi lapang, pengumpulan data, dan analisis data menggunakan empat dari tujuh alat bantu pengendalian mutu yang terdiri dari: lembar periksa, stratifikasi, diagram pareto, dan diagram Ishikawa. Hasil pengamatan menunjukkan terdapat lima jenis kerusakan produk yaitu bantat (38%), terpotong (31%), pecah (28%), gosong (2%), dan tidak terjadi kerusakan lainnya pada produk. Fokus perbaikan kerusakan roti bantat dilakukan dengan penyempurnaan metode pengadukan adonan dan pembuatan SOP peletakan adonan, perawatan alat, serta penambahan operator pada proses panning dan proofing. Hasil uji coba menunjukkan terjadi pengurangan jumlah kerusakan produk sebesar 48,57%., Gaspol burger bread is one of the main products at PT Indo Primafood Abadi. Product quality is a crucial indicator for the company to compete in the market. To maintain the quality of bread products in accordance with the company's specifications and regulations, a well-standardized production system is required. Poor product quality can lead to decreased product quality and company profitability. This research aims to identify and analyze the types of damage that occur during the factors that cause it and evaluate the production process system through the company's internal audit. Data on product damage were obtained through field observations, data collection, and data analysis using four out of seven quality control tools consisting of check sheets, stratification, pareto diagrams, and Ishikawa diagrams. The results of the observations indicate five types of product damage: flattened (38%), sliced (31%), broken (28%), burnt (2%), and there is no other damage to the product. The focus on repairing damage to bantat bread was carried out by improving the dough mixing method and preparation of SOP for laying dough, equipment maintenance, and adding operators to the panning and proofing processes. The test results showed a reduction in product defects by 48.57%.

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.
