Judul: Produktivitas, Potensi dan Prospek Pengembangan Sapi Bali (Bos javanicus) di Desa Pa’rappunganta Kabupaten Takalar Sulawesi Selatan
Abstrak: Bali cattle is one of Indonesia indigenous cattle with high adaptivity of environment and feed. The aims of this study was to determine the productivity, potency, and development prospect of bali cattle in Pa'rappunganta village. This research was conducted from July to August 2011 in Pa’rappunganta village, Takalar region, South Sulawesi. Primary data was obtained through interviewed of 42 farmers. Secondary data was obtained from the village government and related agencies. Data of village profile, farming management and resources were analyzed descriptively. This study also analyzed reproductive characteristic, SWOT (strengths, weaknesses, opportunities and threats) and Increasement Population Capacity of Ruminant (IPCR). The results showed that the age of first oestrus in female bali cattle average was 2,1 years and age of first mating was 2,2 years. Service per conception (S/C) was on average 1,9 times and calving rate mean was 98,1%. Oestrus postpartum of bali cattle in this study was an average of 81.95 days, calving interval was 370±36 days and calf mortality was 5,8%. Result of IPCR analysis showed that capacity of ruminant increase was 137,97 Animal Unit. The result indicated that bali cattle still potential to be developed in Pa’rappunganta village. Result of SWOT analyzed and IPCR showed that bali cattle had a good prospect to be developed in Pa’rappunganta village.

Judul: Production Performance of Bali Cattle at Kuamang abadi of Sekolah Peternakan Rakyat at Bungo District, Province of Jambi
Abstrak: Sapi bali merupakan ternak asli Indonesia yang mempunyai potensi genetik dan nilai ekonomis yang cukup potensial untuk dikembangkan. Sekolah Peternakan Rakyat (SPR) Kuamang Abadi Kabupaten Bungo memiliki potensi pengembangan sapi yang luas, dengan 90% populasinya adalah sapi bali. Penelitian bertujuan mengetahui tingkat kinerja produksi sapi bali di sekolah peternakan rakyat Kuamang Abadi, Kecamatan Pelepat Ilir, Kabupaten Bungo dengan dilihat dari data morfometrik (ukuran-ukuran tubuh), sistem manajemen pemeliharaan (intensif, semi intensif, ekstensif) dan kategori umur yang berbeda. Pada penelitian ini sapi bali yang diamati sebanyak 185 ekor, dengan sistem pemeliharaan dan umur yang beragam. Data produktivitas dianalisis menggunakan analisis deskriptif dan Rancangan Acak Lengkap (RAL) Faktorial dengan 2 faktor perlakuan yaitu Sistem Pemeliharaan dan Umur dengan ulangan yang berbeda. Hasil yang diperoleh di Sekolah Peternakan Rakyat (SPR) Kuamang Abadi tidak menunjukan perbedaan morfometrik tubuh yang berbeda nyata, baik yang dipelihara secara intensif, semi intensif maupun ekstensif. Sedangkan pada kategori umur yang berbeda terdapat perubahan ukuran tubuh yang berbeda nyata dari setiap kategori umurnya ( < 1 tahun, 1- 2 tahun dan >2 tahun). Meskipun demikian, jika dilihat dari morfometrik pada sapi bali di Sekolah Peternakan Rakyat (SPR) Kuamang Abadi hasilnya sudah cukup baik., Bali cattle are native Indonesian cattle that have potential genetic and economic value to be developed. Sekolah Peternakan Rakyat (SPR) of Kuamang Abadi, District of Bungo has wide potential for cattle development, with 90% of the population being Bali cattle. This study aims to determine the performance level of bali cattle production at the SPR of Kuamang Abadi, District of Bungo by looking at morphometric data (body measurements), maintenance management systems (intensive, semi-intensive, extensive) and different age categories. In this study, 185 bali cattle were observed, with various rearing systems and ages. Productivity data were analyzed using descriptive analysis and Factorial Completely Randomized Design (CRD) with 2 treatment factors, namely the maintenance system and age with different replications. The results obtained at the SPR of Kuamang Abadi did not show significant differences in body morphometrics, whether reared intensively, semi-intensively or extensively. Meanwhile, in different age categories, changes in body size were significantly different from each age category (< 1 year, 1-2 years and > 2 years). However, when viewed from the morphometrics of bali cattle at the SPR of Kuamang Abadi the results are quite good.

Judul: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
