Judul: Pengaruh Cuaca terhadap Keragaman Endoparasit pada Macaca fascicularis dan Potensi Zoonotiknya di Kota Kupang
Abstrak: Monyet ekor panjang (Macaca fascicularis) termasuk dalam kategori beresiko rendah, sehingga banyak dijumpai di berbagai wilayah di Indonesia, termasuk Kota Kupang, Nusa Tenggara Timur. Habitat monyet ekor panjang juga merupakan salah satu destinasi wisata sehingga menimbulkan interaksi antara manusia dengan monyet ekor panjang. Interaksi ini memudahkan terjadinya transmisi agen penyakit, salah satunya endoparasit. Penelitian ini bertujuan untuk mengetahui keragaman dan prevalensi endoparasit pada monyet ekor panjang, pengaruh cuaca, serta potensi zoonotiknya di Kota Kupang. Sampel yang diambil berupa feses dan diperiksa menggunakan metode formalin ethyl acetate concentration technique (FECT). Endoparasit yang ditemukan pada monyet ekor panjang di Kota Kupang pada bulan Februari dan November 2017 terdiri atas cacing tambang, Strongyloides, Toxocara, Balantidium coli, Entamoeba coli, dan Entamoeba histolytica. Prevalensi infeksi cacing tertinggi terjadi pada bulan November dengan curah hujan sebesar 302.4 mm dan terdiri atas cacing strongyloid sebesar 86% dan protozoa berupa Balantidium coli sebesar 66%. Semakin tinggi curah hujan, maka prevalensi juga semakin meningkat. Tingginya prevalensi tidak selalu berarti hewan tersebut sakit, akan tetapi apabila dalam feses hewan telah ditemukan telur cacing, maka status hewan tersebut adalah terinfeksi parasit (karier). Tingginya prevalensi helmintiasis pada monyet ekor panjang disebabkan oleh tidak adanya program penggunaan antelmintik (program deworming). Di antara endoparasit yang telah ditemukan, beberapa di antaranya berpotensi zoonosis seperti Strongyloides sp., Toxocara sp., Acanthocephala, dan Entamoeba sp.

Judul: Infeksi Cacing Nematoda pada Saluran Pencernaan Monyet Ekor Panjang (Macaca fascicularis) di Matraman, Jakarta dan Taman Wisata Alam Telaga Warna, Bogor
Abstrak: Gastrointestinal nematode are common parasite found in warm-blooded animals, including Macaca fascicularis. Infection transmission of parasitic nematode in M. fascicularis can occur intraspesies and interspesies. The existence of macaque in homesite at Matraman, Jakarta allowing the parasite transmission from monkeys to humans, or vice versa. Free-living macaque’s in Nature Recreational Park of Telaga Warna are used as a benchmark to determine the prevalence of gastrointestinal nematode infection. Identification results of nematode eggs and larvae in monkeys on Matraman showed Strongyloides 66.67%, Trichostrongylus 58.33% Oesophagostomum 50% and hookworm 45.83%. Identification of nematode eggs and larvae in monkeys at Telaga Warna showed Strongyloides 14.29%, Oesophagostomum 19.05%, Trichostrongylus 19.05%, hookworm 14.29%, Trichuris 14.29% and Ascaris 9.52%. Total prevalence of monkeys in Matraman was at 80.95% and in Telaga Warna 52, 38%. Infection prevalence of parasitic nematode in M.fascicularis seattlement area are bigger than the natural habitat.

Judul: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
