Judul: Analisis Kelayakan Investasi Perancangan Pabrik Label Indikator Pendeteksi Kerusakan Daging Segar
Abstrak: Label indikator merupakan teknologi kemasan cerdas yang telah lama dikembangkan sebagai pendeteksi kerusakan produk yang disebabkan oleh mikroorganisme. Namun label indikator di Indonesia masih di kembangkan dalam skala labolatorium, sehingga perlu dilakukan peningkatam skala menjadi skala pabrik. Tujuan yang ingin dicapai dalam penelitian ini adalah diperolehnya kelayakan investasi perancangan pabrik label indikator kerusakan daging segar, melalui analisis teknis dan teknologi, perancangan peralatan dan analisis kriteria investasi. Kapasitas produksi label indikator sebanyak 5000 label perhari. Kesesuaian alat yang digunakan dan kondisi steril merupakan hal yang perlu diperhatikan karena produk label indikator rentan dengan kontaminasi mikroba. Analisis kriteria investasi meliputi Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit Cost Ratio (Net B/C), Pay Back Period (PBP), dan Break Event Point (BEP). Hasil analisis kriteria investasi menunjukan bahwa pendirian pabrik label indikator layak untuk didirikan. Modal investasi tetap yang dibutuhkan (Rp 741 010 310), modal kerja (Rp 339 964 253), NPV (Rp 1 075 454 656), IRR (57%), Net B/C (5.02), PBP (2.1) dan BEP (26.90 %).

Abstrak: Label indikator merupakan teknologi kemasan cerdas yang telah dikembangkan sebagai pendeteksi kerusakan produk yang disebabkan oleh mikroorganisme. Label ini diletakkan pada kemasan produk dan akan berubah warna jika terjadi penurunan kualitas dari fillet ikan. Penelitian bertujuan untuk mengkaji kelayakan pendirian industri label indikator kerusakan fillet ikan yang meliputi aspek pasar, aspek teknis dan teknologi, aspek manajemen organisasi, aspek finansial termasuk analisis sensitivitas. Kapasitas produksi label indikator sebanyak 6 000 label perhari. Modal investasi total yang diperlukan dalam industri label indikator adalah sebesar Rp 432 954 504 dengan modal investasi tetap yang diperlukan adalah Rp 302 131 570 dan modal kerja sebesar Rp 130 822 934. Berdasarkan kriteria kelayakan finansial, industri layak untuk dijalankan dengan NPV yang didapatkan sebesar Rp 613 871 627, IRR sebesar 24.88%, gross B/C ratio sebesar 2.42, dan PBP selama 7 tahun 8 bulan. Berdasarkan analisis sensitivitas, jika biaya bahan baku naik 5%, biaya tetap naik 12% dan harga jual turun 3.5% maka industri ini tidak layak untuk didirikan., The indicator label is a smart packaging technology that has been developed to detect product damage caused by microorganisms. This label is placed on the product packaging and will change color if there is a decrease in the quality of the fish fillet. This study aims to assess the feasibility of establishing an industrial fish fillet damage indicator label which includes market aspects, technical and technological aspects, organizational management aspects, financial aspects including sensitivity analysis. The production capacity of indicator labels is 6 000 labels per day. The total investment capital required in the indicator label industry is Rp 432 954 504 with the fixed investment capital required is Rp 302 131 570 and working capital is Rp 130 822 934. Based on the financial feasibility criteria, the industry is feasible to run with an NPV obtained of Rp 613 871 627, IRR of 24.88%, gross B/C ratio of 2.42, and PBP for 7 years and 8 months. Based on the sensitivity analysis, if the cost of raw materials increases by 5%, fixed costs increase by 12% and the selling price decreases by 3.5%, then this industry is not feasible to establish.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
