Judul: Overview of Broiler Chicken Slaughtering Result Sold at Traditional Markets in Bogor
Abstrak: Penelitian ini bertujuan untuk mendeskripsikan kesempurnaan proses penyembelihan ayam broiler yang dijual di pasar tradisional di Kota Bogor. Sebanyak 475 sampel dibeli dari 95 pedagang yang berada di dalam dan di luar kios. Sampel dipreparir menggunakan alat bedah minor untuk mengidentifikasi saluran trakea, esopagus, dan kedua arteri carotis interna. Jumlah penyimpangan penyembelihan yang terjadi sebanyak 361 sampel (76%). Penyimpangan penyembelihan yang terdapat di dalam kios sebesar 39%, sedangkan penyimpangan yang terjadi di luar kios sebesar 37%. Hasil yang diperoleh menunjukkan buruknya proses penyembelihan. Penelitian ini diharapkan dapat memberikan informasi kepada pengambil kebijakan dan pengawas terkait keamanan dan kelayakan pangan tentang teknik penyembelihan yang baik dan benar pada ayam broiler.

Judul: Kualitas mikrobiologis karkas ayam broiler selama pemasaran pada pasar tradisional di Bogor
Abstrak: Chicken meat is an important protein source which has relatively low in price. The demand of chicken carcass increases year by year, but it is not followed by the development of carcass handling procedurs in traditional market, especially in Indonesia This fact resulted that chicken carcass easily conlaminated by microorganism, so the quality decreased In traditional market, chicken carcass sold in open air and room tempemhm without any package. The objective of this research was to study microbial quality of broiler carcass during marketing process on traditional market in Bogor. This research studied about total microorganism, total coliform and Salmonella, in 6 hour marketing process in traditional market.

Judul: Density funtional theory dalam sintesis, karakterisasi, dan prediksi aplikasi. Kasus: senyawa Zn-dialkylditiokarbamat rantai panjang
Abstrak: Coordination compounds of dialkyldithiocarbamate have broad applications, e.g. automotive lubricant additives. Coordinated long chain dialkyldithiocarbamate was studied to obtain the better anti-friction and anti-wear. Integration of computation chemistry e.g. density functional theory used to identify reaction mechanisms, to optimize geometry of structure, and to estimate properties of compounds. The aim of this study was to obtain long chain complexes Zn-dialkyldithiocarbamate, to examine their structures, and to estimate their applications using Density Functional Theory methods (DFT). Long chain Zn-dialkyldithiocarbamate was synthesized through reaction between ZnCl2, NaOH, CS2 and secondary amine during 24 hours in room condition. Secondary amine was obtained from LiAlH4 reduction of amide 2o during 24 hours in nitrogen atmospheric. Reaction of long chain amine 1o and long chain acylchloride was used to obtain amide 2o. DFT and instrumentation (FTIR and HPLC) was used to study of mechanism, structure elucidation and its application. The results showed the synthesis of Zn-dibutyldithiocarbamate, dipalmitilamide, dipalmitilamine, Zn-dipalmitildithiocarbamate yields are 90.02%, 90.91%, 47.5%, and 66.49% respectively. The ratio of intensity and wave number for Zndibutyldithiocarbamate from FTIR spectra and DFT calculations wasn’t significantly different at 95% confidence level. According to DFT calculation (B3LYP/ 6-31G*), the carbon-sulfur bonds in Zn-dibutyldithiocarbamate have an average length of 0.1683-0.1743 nm and the ligand “bite” angle S-C-S has a mean value of 116.85o. This result indicates a tetrahedral-shaped Zndibutyldithiocarbamate. Lubricant additives (anti-wear and anti-friction) properties of Zn-dialkyldithiocarbamates was estimated by chemical hardness and absolute electronegativity. Lower electronegativity value is better anti-friction, and lower chemical hardness is better anti-wear. Anti-friction ability of Zndialkyldithiocarbamate is better than Mo-dialkyldithiocarbamate, while anti-wear ability is lower than Zn-dialkiydithiophosphates. Based on electronegativity absolute value of DFT calculations, the Zn-dialkyldithiocarbamate is categorized as superlubricity that can perform in the boundary lubricant system.
