Judul: Dynamics System Modeling for Rice Stock
Abstrak: Rice production in Indonesia is characterized by large number of people and institutions involved in the business and wide spread of distribution area. There are two kinds of rice sources namely in country farmers production and the imported one. From these two sources rice is distributed throughout the country through many channels of marketing and distribution. The dynamics of rice supply and its distribution is mainly affected by factors of season, harvest field availability and its productivity, rate of harvesting failure, in country prices, import barrier, government involvement, and quality of infrastructure. A system dynamics model of rice stock was constructed using ithinkTM software. The model attempts to figure out the behaviour of rice stock system by simulation technique. The system was represented by ten subsystems which are interacting one to another. These ten subsystems were farmers, rice millings, KUD, collector traders, Bulog, grociers, importers, national stock. The interaction between each subsystem is depicted by a causal diagram, following the systems dynamics approach. The sensitivity of the model can be tested by running the model under certain set of values of key parameters and variables. The simulation resulted in two important findings. First, the model was able to picture the dynamics of rice distribution among ten subsystems assigned. Second, the value of stocks at each subsystem were considerably resembling the actual stocks at each subsystem. These results enabled the model to be used as a predicting tool or simulation tool for rice stock distribution.

Judul: Model design of intelligent decision support system for rice supply chain System in DKI Jakarta province
Abstrak: DKI Jakarta is the region which has a very large population but it is not supported directly by rice field area that can meet the needs of rice for its population. Cipinang rice market center (PIBC) managed by PT. Food Station Tjipinang Jaya (FSTJ) is expected to be a party that can manage and control the rice for food security, especially in the Jakarta area. There are several important aspects to be considered by FSTJ in regulating and controlling food security. These aspects are the supply of rice, rice price, rice supplier selection, transportation and distribution aspects of rice as well as the performance aspect of the rice supply chain. The purpose of this study was to develop a model of intelligent decision support system for rice supply chain that covers all these aspects effectively and efficiently. There were several methods used in this study. Artificial neural network was used to analyze aspects of the supply and price of rice, TOPSIS was used to analyze the rice suppliers selection, simulated annealing was used to analyze the distribution and transportation of rice and fuzzy inference system was used to analyze the performance of the rice supply chain. Analysis results showed that the accuracy of forecasting models to forecast the supply of rice and to forecast rice prices have reached more than 90 percent. Rice supplier selection model is effectively able to sort the suppliers of rice based on predetermined criteria. Transportation and distribution model has effectively been able to make the shortest route to distribute the rice. This model also has been able to make the sequence assignment of vehicles to deliver the rice to its customers. Finally, the rice supply chain performance model also effectively has been able to measure the performance of supply chain that accommodates the input factors. According to the results of analysis and experts opinion, there were advantages and disadvantages of the model produced, but they can be verified and they were also valid.

Judul: Studi Kasus: Patomorfologi Trakheobronkhitis Supurativa Pada Kucing (Felis Catus).
Abstrak: Trakheobronkhitis merupakan penyakit saluran respirasi yang sering terjadi pada hewan kecil, terutama anjing dan kucing. Penelitian berupa studi kasus ini bertujuan untuk mempelajari patomorfologi trakheobronkhitis supurativa pada kucing. Perubahan patologi anatomi berupa eksudat purulen pada lumen trakhea dan warna paru-paru yang tidak homogen, warna lebih gelap pada salah satu lobus, dan permukaan paru-paru lebih menonjol. Perubahan histopatologi berupa badan inklusi amfofilik-eosinofilik intranuklear yang dikelilingi oleh clear halo dan titik-titik kromatin ditepinya pada epitel kelenjar trakhea dan epitel bronkhiolus. Badan inklusi ini merupakan ciri dari FHV-1 dan adenovirus. Pada trakhea juga ditemukan koloni bakteri berbentuk coccobacillus sebagai infeksi sekunder. Bakteri tersebut diduga Bordetella sp. yang sering menginfeksi saluran respirasi kucing. Deskuamasi terjadi pada epitel trakhea dan bronkhiolus. Selain itu, ditemukan juga sel radang limfosit, makrofag, sel plasma, dan neutrofil. Pada paru-paru ditemukan lesio bronkhiolitis. Ditemukan juga bronkhopneumonia yang ditandai infiltrasi sel radang neutrofil dan sel nekrosis pada lumen bronkhiolus. Paru-paru juga mengalami emfisema dan edema pulmonum. Hiperemia dan hemoragi juga ditemukan pada kapiler paru-paru. Pada kasus ini, trakheobronkhitis supurativa diduga disebabkan oleh FHV-1, adenovirus, dan bakteri jenis Bordetella sp.
