Judul: Studi Kelayakan Pendirian Industri Tahu Kemasan di Kabupaten Mojokerto
Abstrak: Industri tahu di Kabupaten Mojokerto saat ini memiliki dua permasalahan yaitu tingkat higienitas produk dan umur simpan yang relatif singkat. Kedua hal tersebut dikarenakan keterbatasan keuangan. Oleh karena itu, Penelitian ini bertujuan mengetahui kelayakan pendirian industri tahu dengan penambahan kemasan dan penggunaan peralatan stainless steel di Kabupaten Mojokerto serta membandingkan tingkat keuntungan pendirian industri tersebut. Metode yang digunakan ialah metode deskriptif dengan melakukan studi kelayakan yang meliputi analisa dari aspek pasar dan pemasaran, aspek teknis dan teknologis, aspek manajemen dan organisasi, aspek lingkungan, serta aspek finansial. Hasil penelitian didapat bahwa industri tahu kemasan akan mendapatkan laba dengan batas minimum penjualan 60% dari kapasitas produksi. Perhitungan analisis finansial dilakukan dengan membandingkan 3 sumber modal antara lain : modal sendiri, modal dari kerabat dan modal dari bank. Dari perhitungan analisis finansial diperoleh bahwa modal sendiri lebih layak dan menguntungkan dibandingkan dengan lainnya dengan NPV Rp. 9 183 201 000, IRR 33%, B/C ratio 1.29, dan payback period selama 43 bulan.

Penelitian ini bertujuan untuk mengetahui kelayakan pendirian industri tepung mocaf di kabupaten Bogor. Metode yang digunakan adalah metode analisis kelayakan investasi. Hasil penelitian menunjukkan bahwa permintaan pasar terhadap tepung mocaf mencapai lebih dari 1 juta ton/tahun. Kapasitas industri mocaf direncanakan sebesar 50 ton singkong/hari, berlokasi di kecamatan Sukaraja, kabupaten Bogor. Investasi yang dibutuhkan sekitar 18,2 miliar rupiah, terdiri dari investasi modal tetap sebesar 10,7 miliar rupiah dan modal kerja 5,4 miliar rupiah. Kriteria investasi menunjukkan nilai Net Present Value sebesar Rp 23.972.970.000, IRR 28,7%, B/C Ratio 1,67, dan Pay Back Period sebesar 2,12 tahun. Analisis titik impas menunjukkan bahwa pada tahun pertama harus memproduksi minimum 21.200 ton. Analisis sensitivitas menunjukkan bahwa industri layak didirikan bila maksimum kenaikan harga beli bahan baku singkong sebesar 7%, penurunan harga jual tepung mocaf maksimum sebesar 5%, dan penurunan kapasitas produksi maksimal sebesar 35%. Berdasarkan seluruh analisis yang dilakukan, industri tepung mocaf layak didirikan di kabupaten Bogor.

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.
