Judul: Sistem Pendukung Keputusan Penyediaan Dokumen dalam Pengajuan Sertifikasi Halal.
Abstrak: Pemerintah Indonesia mengeluarkan Undang-undang No.33 Tahun 2014 sebagai bentuk perlindungan terhadap konsumen muslim dalam mengatasi masalah halal. Undang-undang tersebut mewajibkan produk yang masuk, beredar dan diperdagangkan di Indonesia memiliki sertifikat halal. MUI (Majelis Ulama Indonesia) memberikan dukungan pendaftaran online, yang dikenal dengan CEROL (certification online) untuk mempermudah proses pengajuan sertifikasi halal. Cepat atau lambatnya proses pengajuan tersebut bergantung pada ketepatan dan kelengkapan dokumen persyaratan yang diajukan. Penelitian ini bertujuan menghindari pengulangan proses pengisian data bahan dan penundaan proses pengajuan sertifikasi halal yang disebabkan karena kesalahan dalam melampirkan dokumen yang diperlukan. Salah satu penyelesaian yang praktis dan akurat adalah dengan mengembangkan sistem pendukung keputusan untuk penentuan dokumen pendukung bahan, yang disebut sebagai SPK PDPB. SPK PDPB telah dikembangkan ke dalam sistem berbasis web dengan menggunakan bahasa pemrograman hypertext prepocessor (PHP) dan database management system MySQL (my structured query language). Jenis dokumen pendukung yang menjadi keluaran dari sistem ini terdiri atas diagram alir proses, spesifikasi teknis, COA (Certificate of Analysis) atau dokumen pembelian bahan, sertifikat halal dan dokumen kosong. Dukungan keputusan yang diberikan oleh sistem berdasarkan pada aturan penentuan kategori titik kritis bahan yang dikeluarkan MUI pada Panduan umum sistem jaminan halal dan 4 parameter tambahan, yaitu sumber bahan baku, sumber bahan tambahan, titik kritis bahan dan ada/tidaknya proses tambahan pada bahan yang digunakan dalam pembuatan suatu produk. Penentuan 4 parameter pengambilan keputusan tersebut berasal dari penerapan metode pohon keputusan dengan model J48 yang diterapkan menggunakan aplikasi Weka. Jumlah data yang digunakan pada tahap analisis penentuan dokumen pendukung bahan ini berjumlah 738 data dan dibedakan menjadi 80% data latih dan 20% data uji. Hasil akurasi aturan pengambilan keputusan yang dihasilkan adalah 99,3%. Fitur yang terdapat pada SPK PDPB, yaitu penentuan dokumen pendukung bahan, pencarian informasi data bahan, jenis dokumen pendukung bahan dan sertifikasi halal, dan juga penampungan aspirasi pengunjung website. Sistem ini dibagun dengan menerapkan SDLC (system development life cycle) dan menghasilkan sistem yang dapat menjadikan proses penentuan dokumen pendukung bahan lebih mudah dengan hasil yang tepat. Saat ini penentuan dokumen pendukung bahan pada parameter proses tambahan hanya berfokus pada ada atau tidaknya proses tersebut. Diharapkan kedepannya nilai dari parameter tersebut dapat mencakup nilai pengolahan bahan secara detail seperti mencantumkan nama proses, bahan tambahan dan bahan penolong yang digunakan.

Judul: Implementasi Sistem Sertifikasi Halal Berbagai Kategori Industri Pangan dan Uji Coba Implementasinya di Kantin Sapta- Fateta-IPB
Abstrak: Consuming halal food is a mandatory for every Muslim. For this reason, it is important for food producers to provide halal food. Demand of halal food increases significantly in line with the growth of Muslim population and the awareness of Muslim to consuming halal food. Due to the high population of Muslim around the world halal food production has become the concern of food industries in the last twenty years, including in Indonesia. The assurance of halal food production by food industries was done through certification process. In Indonesia, the process of halal certification was conducted by an independent agency under the Indonesian Council of Ulama (MUI), namely the Institute for Foods, Drugs and Cosmetics (LPPOM MUI). Indonesia has become the pioneer in establishment of halal certification system. Currently LPPOM MUI has established Halal Certification Online Service System (CEROL-SS23000) in order to facilitate the registration of manufacturers and halal certification process. The objectives of this internship program was to study the halal certification system for various food industry categories conducted by LPPOM MUI, through the Certification Online Service System (CEROL system), and implementation through the preparation of halal certification in the catering Sapta-Fateta-IPB. The primer data was obtained through survey to some categories of food industries to evaluate Certification Online Service System (CEROL-SS23000) based on producer perception.

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.
