Judul: Identifikasi Protozoa Parasitik pada Tinja Owa Jawa (Hylobates moloch Audebert 1798) di Habitat Ex Situ
Abstrak: SALSABILA YAZTHI. Identification of Parasitic Protozoa From Faeces of Silvery Javan Gibbons (Hylobates moloch Audebert 1798) in Ex Situ Habitat. Under direction of SRI UTAMI HANDAJANI. This study was aimed to observe the existence of parasitic protozoa in faeces sample, that were collected from silvery javan gibbons (Hylobates moloch Audebert 1798) in ex situ habitat. It has been evaluated a probability of a protozoa transmission through the feeding, water, cage sanitation or animal care. Faeces were collected from silvery javan gibbons at The Primate Research Center of Bogor Agricultural University and The Javan Gibbon Center, Bodogol, Gunung Gede Pangrango National Park, Sukabumi. Faeces examination using natif and flotation methods. No parasitic protozoa found in silvery javan gibbons’s faeces from The Primate Research Center, while it was found in silvery javan gibbons’s faeces from The Javan Gibbon Center. The genus of protozoa were Entamoeba and Balantidium. The existence of these parasitic protozoa closely related to the care programs, such as feeding, cage and healthy management of silvery javan gibbons in ex situ habitat. A good care program can minimize the risk of infection from parasitic protozoa and transmission of any animal or human resources working with the gibbons.

Judul: Cacing parasitik pada ungko (Hylobates agilis F.Cuvier 1821) dan siamang (Symphalangus syndactylus Raffles 1821) di Taman Rekreasi Margasatwa Serulingmas Banjarnegara
Abstrak: Agile gibbon (Hylobates agilis F. Cuvier 1821) and siamang (Symphalangus syndactylus Raffles 1821) are Indonesian endemic species. Aim of the study to determine the existence and the type of parasitic worms that infected agile gibbon and siamang at Serulingmas Zoological Garden, Banjarnegara. From Juli 2009 to February 2010, feces from three heads of agile gibbon and three heads of siamang was collected each week. All of samples were examined with quantitative and qualitative examination. Identification is achieved by the use of faecal cultures. The result showed that parasitic worms of agile gibbon were Trichostrongylus spp. and Strongyloides spp. and parasitic worms of siamang were Trichuris spp., Trichostrongylus spp., Strongyloides spp., and Cooperia spp. The result of quantitative examination showed that degree of infection by parasitic worms in agile gibbon and siamang belonging to low infection.

Judul: Strategi Long Straddle dan Bull Spreads untuk Lindung Nilai Crude Oil
Abstrak: Konflik Geopolitik Rusia-Ukraina, pemotongan produksi OPEC+, dan China mempercepat vaksinisasi menyebabkan harga crude oil meningkat. Lindung nilai menggunakan strategi opsi dapat menjadi solusi untuk mengurangi risiko jika menghadapi kondisi bullish di masa depan. Penelitian ini menggunakan tiga strategi opsi, yaitu long straddle, bull call spread, dan bull put spread. Berdasarkan hasil perhitungan, ketiga strategi opsi memiliki keuntungan maksimum dan kerugian maksimum pada kondisi dan nilai yang berbeda-beda jika terjadi peningkatan spot price. Long straddle lebih menguntungkan pada kondisi bullish atau bearish, sedangkan bull call spread lebih menguntungkan pada kondisi neutral. Harga jual lindung nilai long straddle merupakan yang terendah pada kondisi bearish dan bullish, sedangkan pada kondisi neutral harga jual lindung nilai terendah terjadi ketika diterapkan strategi bull call spread.
