Judul: Inseminasi buatan pada kelinci
Abstrak: Di Indonesia, upaya pemerintah untuk memenuhi kebutuhan protein hewani antara lain dengan jalan mengembangkan usaha ternak kelinci karena kelinci mampu tumbuh dan berkembangbiak dengan cepat, dagingnya mempunyai kandungan zat-zat makanan yang tidak kalah dengan ternak lainnya, mampu memanfaatkan hijauan dalam jumlah besar dan mudah dipelihara. Disamping itu kulitnya dapat digunakan untuk bahan kerajinan tangan seperti tas, topi, hiasan dinding dan lain-lain; kotorannya dapat dimanfaatkan sebagai pupuk kandang. Untuk mempertinggi produktivitas kelinci, inseminasi buatan (IB) dapat digunakan pada perkembangbiakannya. Prosedur IB pada kelinci meliputi seleksi dan pemeliharaan pejantan; penampungan, penilaian, pengenceran, penyimpanan atau pengawetan dan pengangkutan semen; induksi ovulasi; inseminasi dan evaluasi hasil inseminasi pada betina, Penampungan, penilaian, pengenceran, penyimpanan atau pengawetan dan pengangkutan semen kelinci pada prinsipnya sama dengan ternak lainnya. Tidak seperti ternak mamalia umumnya, inseminasi pada kelinci harus didahului dengan induksi ovulasi sebab kelinci termasuk ovulator induksi.

Judul: Formulasi Oil Spill Dispersant (OSD) dengan Bahan Baku Surfaktan Metil Ester Sulfonat (MES) dan Dietanolamida (DEA).
Abstrak: Environmental pollution which caused by the oil spill can be dealt with the physical, chemical and biological treatments. Physically treatment was done by isolate the petroleum quickly before spread to the environment. Meanwhile, chemical treatment was relatively short to manage oil spill, but this treatment had disadvantage cause by application of chemicals which less environmental friendly. Of the chemical treatments is oil dispersion by using oil spill dispersant (OSD). OSD is a product with composition of some chemicals and surfactants that aims to disperse the waste oil to be degraded in the environment. Based on previous research, the modern OSD composition consisted of nonionic and anionic surfactants, so dietanolamide (DEA) as nonionic surfactant and methyl Ester Sulfonate (MES) as anionic surfactant were used in this research. This research aims to produce formulated surfactant as an oil spill dispersant (OSD) which consists of DEA, MES and solvent and then tested on a simulation of marine pollution. The research was divided into three steps: the first step was synthesis of MES and DEA as raw material of OSD formulation, the second step was formulation process of OSD by mixing the two raw materials at variation of concentration and volume ratio. This step aims to find the best formulated OSD. The third step was a testing the performance of the best formulated OSD by oil spill simulation. In the first step, the raw material of DEA and MES were produced at an optimum conditions of previous studies. In the second step, characterization of OSD product by analyzing of emulsion stability, density, surface tension, viscosity and pH. Some of these parameters were used to determine the best formulation of OSD. The best formulation of OSD was conducted in performance test in simulated oil spill using 10ml crude oil in 1 L sea water media and then it to be dispersion. The dispersion oil in sea water were analyzed to chemical oxygen demand (COD), biological oxygen demand (BOD), total petroleum hydrocarbons (TPH), density, and pH. The formulation of OSD was made by mixing two surfactant solutions including DEA solution with concentration of 1, 2, 3, 4, 5 % and MES solution of 1, 2, 3, 4, 5, 10, 15 %. Both of surfactant solution were mixed with volume ratio of 1: 3, 1: 1 and 3: 1 at temperature of 50C for 60 min. The result showed that the best formulated OSD was at mixing of 3% DEA and 5% MES solutions with volume ratio of 1 : 3. The OSD product showed excellent stability (> 80%) with a good properties including density of 0.90 g/cm3, the surface tension of 25.59 mN/m, pH 9.1, and a viscosity of 131 cP. The performance test of OSD carried out by simulation of oil spill in sea water with application of ratio of volume OSD to volume oil spill. Addition of OSD was expected could increase to the dispersion of oil in sea water. The performance test of OSD showed that 2 mL OSD in 10 mL simulated oil spill (ration 0.2) capable to dispersing of oil at 85.75 %,
