Judul: Institutional system engineering support for quality assurance of raw material supply of cattle hides for gelatin agro industry development
Abstrak: In the supply of quality and halal products, there are several criteria that must be fulfilled in terms of types of material, the preparati on method and the effort to obtain it. Although the reviewed product derived from cattle hides, this product cannot be automatically considered as a halal product, without getting through traceability process and the applicable halal standardization in advance. A traceability of gelatine raw material would require an effective system for the users in collecting information about the origin of raw materials and the materials management process at every stage of the process, starting from raw materials to finished product. The traceability system involves various parties who have different needs and goals in the process of supplying raw materials. Therefore, there should be institutional system engineering that can manage and handle the traceability process and the procurement of gelatine raw materials in order to provide assurance for the origin of raw materials and facilitate the industry, as well as the users of gelatine in making the standardization of quality, such as halal standards.

Judul: Pengembangan Model Sistem Traceability Rantai Pasok Daging Sapi Berbasis Teknologi Informasi
Abstrak: Undang-Undang Pangan (UU No 18, 2012) mendefinisikan ketahanan pangan sebagai kondisi terpenuhinya Pangan bagi negara sampai dengan perseorangan, yang tercermin dari tersedianya Pangan yang cukup, baik jumlah maupun mutunya, aman, beragam, bergizi, merata, dan terjangkau serta tidak bertentangan dengan agama, keyakinan, dan budaya masyarakat, untuk dapat hidup sehat, aktif, dan produktif secara berkelanjutan. Salah satu komponen penting ketahanan pangan adalah persyaratan keamanan pangan. Untuk mewujudkan ketahanan daging sapi, diperlukan adanya sistem pengelolaan peternakan yang baik, serta untuk menjamin terpenuhinya persyaratan keamanan daging sapi perlu dikembangkan sistem keterlacakan dari daging sapi yang dihasilkan (traceability). Saat ini Indonesia belum memiliki sistem identifikasi ternak nasional yang standar dan aktor-aktor dalam rantai pasak umumnya belum terdaftar dan belum memiliki sistem traceability daging sapi berbasis teknologi informasi yang terintegrasi. Tujuan penelitian ini adalah 1) Menganalisis persepsi konsumen dalam membeli produk daging sapi Aman Sehat Utuh Halal (ASUH), 2) Mengembangakan sistem identifikasi ternak sapi di Indonesia berbasis teknologi informasi (TI), 3) Memetakan dan merancang sistem traceability berbasis teknologi informasi, 4) Mengembangkan prototype sistem traceability berbasiskan teknologi informasi dalam rantai pasok daging sapi, dan 5) Menganalisis penerapan sistem traceability berbasiskan teknologi informasi dalam rantai pasok daging sapi di masa mendatang. Penelitian diawali dengan analisis keinginan membeli daging ASUH sebagai dasar bahwa adanya keinginan dari konsumen terhadap daging yang aman dan perlunya sistem traceablitity. Penelitian ini dimulai dengan survei dengan menyebarkan kuesioner kepada responden yang sudah mengonsumsi produk daging sapi ASUH. Selanjutnya, dilakukan pemetaan rantai pasok daging sapi di Indonesia dengan studi deskriptif dan dilanjutkan dengan pengembangan sistem informasi traceability daging sapi menggunakan Software Development Life Cycle (SDLC) metode prototyping yang diberi nama Sicadas.com. Perancangan dilakukan dengan konsep Computer Base Information System (CBIS) dalam merancang infrastruktur sistem traceability. Analisis implementasi sistem traceability dilakukan dengan melakukan survey terhadap pakar kemudian dianalisis menggunakan ISM. Hasil penelitian menunjukkan bahwa sikap konsumen dan persepsi risiko tidak berpengaruh terhadap kemauan membeli, sedangkan variabel kepercayaan, atribut produk, dan traceability memiliki pengaruh signifikan terhadap keinginan untuk membeli. Selanjutnya, sistem identitas dan database ternak nasional dapat memberikan nomor identitas ternak secara unik dan dapat ditulis ke RFID yang kemudian dapat dipasang di telinga sapi (eartag). Laman Sicadas.com dapat diakses dan digunakan oleh semua aktor pada rantai pasok. Konsumen dapat mengetahui asal usul sapi dan daging dengan melakukan pemindaian pada kode QR. Agar sistem Traceability dapat diterapkan maka dibutuhkan dukungan regulasi dari pemerintah. Meskipun, penerapan sistem traceability ini juga membutuhkan anggaran yang besar untuk instalasi fasilitas dan infrastruktur, pemeliharan serta sumber daya manusia yang kompeten.

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.
