Judul: Designing of quick risk assesment model of food safety for agro-fishery industries
Abstrak: Quick risk assesment model of food safety (Q-RAF) was designed to identify food safety risks in Agro-fishery industries. The model was built was based on the process series from primary untill downstream of Agro-fishery industries. The Q-RAF is divided into four key sub models namely Q-RAF sub Tangkap, Q-RAF sub Penanganan, Q-RAF sub pengolahan, Q-RAF sub base and gate. Similar to other decision support models, Q-RAF is completed by Q-RAF Matrix AA and other relevant information.

Judul: Desain Model Penilaian Udang Ekspor Berbasis Jaminan Mutu dan Keamanan Pangan
Abstrak: As a shrimp exporting country, Indonesia is still facing quality and food safety problems. Shrimp certification system as the policy conducted by the government to assure the implementation of quality and food safety did not perform well yet due to rejection of some exported shrimps from major importing countries. In this research, system approach was used to solve the problems by developing asessments models. The aim of this research is to develop Quality and Food Safety Assurance based-Assessment Model for Exported Shrimps in a software application. Assessment models were developed for several shrimp units in shrimp chain business involved in the implementation of quality and food safety assurance based on quality and food safety standards from government policy and international standards. There are six assessment models that were developed: (1) assessment model for shrimp ponds, (2) assessment model for shrimp fishing units or vessels, (3) assessment model for shrimp importers, (4) assessment model for shrimp collection units, (5) assessment model for shrimp processing units, and (6) assessment model for shrimp analytical laboratories. Shrimp Assessment System 1.0 (ShASy 1.0) is the name of application software had been designed to implement the assessment models. ShASy 1.0 could evaluate the implementation of quality and food safety standards and determine the result (GOOD or NOT GOOD) based on its deviation. ShASy 1.0 was tested and worked properly through the verification models. The actual data for verification models were collected from Ministry of Oceans and Fisheries, Indonesia. The average deviation of quality and food safety implementation from verification results are 72.49% in shrimp ponds, 5% in shrimp importers, 61.54% in shrimps collection units, 20.47% in shrimp processing units, and 62.5% in shrimp analytical laboratories. The results show the lack implementation of quality and food safety assurance in all shrimps units especially in units which had high average deviation value such as shrimp ponds, collection units and analytical laboratories. There is no policy implemented for quality and food safety assurance in shrimp fishing units up till now. Based on verification, several recommendations are given to the government to improve shrimp certification system such as policies and tools for implementing certification in shrimp fishing units and shrimp collection units, standards adjustment for traditional shrimp ponds certification, tightening supervision for certified shrimp processing units, competency improvement for shrimp analytical laboratories, and holding various socialization and training programs for shrimp units.

Judul: Sintesis Superkonduktor YBCO dengan Metode Evaporasi dan Karakterisasinya
Abstrak: Telah berhasil dibuat pelet superkonduktor YBCO-123 dengan metode evaporasi dengan menghasilkan Tc = 100 K. Sintesis dilakukan dengan mencampur garam-garam nitrat Y(NO3)2, Ba(NO3), Cu(NO3)2 di dalam pelarut H2O pada suhu 150 oC. Setelah melalui proses pirolisis pada 350 oC selama 1 jam, prekursor dikalsinasi pada 900 oC selama 4 jam kemudian serbuk dikompaksi dengan tekanan hidrolik 5 ton untuk membentuk pelet dengan diameter 1,5 cm dan tebal 0,24 mm. Sintering dilakukan pada suhu 940 oC selama 20 jam. Efek meissner menunjukkan fenomena levitasi pada temperatur sekitar 80 K. Hal ini menunjukkan fasa superkonduktor telah terbentuk. Data XRD memberi mengkonfirmasi bahwa fasa kristal 123 telah terbentuk. Nilai konduktivitas didapat dari hasil pengukuran dengan LCR pada temperatur 300 K sebesar 4 x 10-5 S/cm. Pada penurunan temperatur dari 100 K ke 80 K terjadi kenaikan nilai konduktansi yang tajam dari 4.2 x 10-4 S/cm ke nilai 1.309 x 10-1 S/cm.
