Judul: Kajian biologis maleo yang dipelihara secara ex situ
Abstrak: Maleo merupakan salah satu burung endemik Sulawesi yang populasinya terancam punah. Guna menjaga ekstensi sekaligus memilihkan populasi maleo, perlu dilakukan kegiatan konsevasi. Konservasi burung dapat dilakukan secara in situ (di dalam habitat alaminya), seperti melalui perlindungan jenis burung, pembinaan habitat dan populasi: dan secara ex situ (di luar habitat alaminya) salah satu diantaranya melalui penangkaran.

Judul: Biologi Perkembangan Burung Maleo (Macrocephalon maleo, Sall, Muller 1846) yang Ditetaskan Secara Ex Situ
Abstrak: Burung maleo (Uacrocephalon maleo) adalah satwa endemik Sulawesi yang memiliki sifat serta tingkah laku unik yang membedakannya dari burung lain yaitu telurnya yang sangat besar dibandingkan dengan besar tubuhnya serta proses penetasannya dimana telur dimasukkan ke lubang dalam tanah. Pengambilan telur secara besar-besaran mengakibatkan ancaman terhadap kelestariannya. Untuk menunjang konservasinya maka penelitian ini dilaksanakan untuk mengkaji morfometri telur, daya tetas telur yang dieramkan dalam mesin tetas (inkubator), perkembangan embrio, perhunbuhan serta gambaran hematologis anak burungnya.

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.
