Judul: Study on Potential Helminthic Zoonosis in Urban Wild Rats in Peninsular Malaysia: An Article Review
Abstrak: Rodents are mammalians group found in worldwide, large population of commensal rodents live proximity with human in urban area may favor the transmission of zoonotic disease. Rodent-borne helminths related diseases are listed as neglected disease, commonly find within mid to low income country. This study aims to identify the potential helminthic zoonotic diseases that might be transmitted via rodents in Peninsular Malaysia. Literature review on studies of helminths in rodents in Peninsular Malaysia within these ten years had been carried out. Those helminths that potentially cause zoonotic diseases had been listed out to further investigate the helminths’ characteristic, lifecycle, transmission mode, and prevention methods. Five studies had been reviewed; four zoonotic diseases had been ruled out with five species of helminths had been identified which are H. nana, H. diminuta, A. malaysiensis, C. hepatica, and M. moniliformis. In which, H. nana and H. diminuta had a higher zoonotic risk than other zoonotic diseases. Most of the zoonotic diseases listed are transmit by accidental ingestion of contaminated foods or drinks. Prevention methods include good hygiene, sanitation and public health practices., Hewan pengerat adalah kelompok mamalia yang ditemukan di seluruh dunia, populasi besar hewan pengerat komensal yang hidup berdekatan dengan manusia di perkotaan dapat mendukung penularan penyakit zoonosis. Penyakit cacing yang ditularkan melalui hewan pengerat telah diklasifikasi sebagai penyakit terabai, umumnya ditemukan di negara pendapatan menengah dan bawah. Penelitian ini bertujuan untuk mengidentifikasi potensi penyakit zoonosis cacing yang kemungkinan ditular melalui hewan pengerat di Semenanjung Malaysia. Tinjauan literatur tentang studi cacing-cacing pada hewan pengerat di Semenanjung Malaysia dalam sepuluh tahun ini telah dilakukan. Cacing-cacing yang berpotensi menyebabkan penyakit zoonosis ditabel; karakteristik, daur hidup, cara penularan, dan cara pencegahannya telah diteliti. Lima studi telah ditinjau, dimana empat penyakit dengan lima spesies cacing telah diidentifikasi yaitu H. nana, H. diminuta, A. malaysiensis, C. hepatica, dan M. moniliformis. H. nana dan H. diminuta memiliki risiko zoonosis lebih tinggi dibandingkan dengan lain. Sebagian besar penyakit zoonosis yang terdaftar ditular melalui konsumsi makanan atau minuman yang terkontaminasi secara tidak sengaja. Metode pencegahan termasuk kebersihan individu, sanitasi dan praktik kesehatan masyarakat yang lengkap.

Judul: Literature Review on Prevalence of Helminths in Urban, Wild, and Captive Non-human Primates in Malaysia
Abstrak: Non-human primates are diverse groups of animals ranging from the Old World to the New World monkeys. Non-human primates are found in the wild, urban areas, and captivity. Gastrointestinal parasites in primates especially soil- transmitted helminths cause zoonotic diseases which most are considered as neglected diseases, commonly found in developing countries. This study aims to review the prevalence of helminths found in non-human parasites which could cause harm to both humans and non-human primates in Malaysia. Literature reviews on studies of helminths in non-human primates living in Malaysia's wild, urban, and captivity have been carried out within the years 2015-2022. Those parasites that potentially cause threats to the population of endangered non-human primates and zoonotic disease via cross-species transmission are identified further to study the characteristics, lifecycle, and prevention methods. Five studies had been reviewed; four species of helminths had been identified: Trichuris sp, Strongyloides sp, Ascaris sp, and Enterobius sp. Trichuris had a high prevalence of 2.2% to 86.6%. Most of the parasites listed are transmitted through the fecal-oral route. Prevention methods include good hygiene routines, proper sanitation, education on public health, and an uplift in socioeconomic status., Satwa Primata adalah beragam kelompok hewan mulai dari monyet Dunia Lama hingga monyet Dunia Baru. Satwa Primata ditemukan di alam liar, perkotaan, dan penangkaran. Parasit gastrointestinal pada primata khususnya cacing yang ditularkan melalui tanah menyebabkan penyakit zoonosa yang sebagian besar dianggap sebagai penyakit terabaikan, yang banyak ditemukan di negara-negara berkembang. Penelitian ini bertujuan untuk meninjau prevalensi cacing yang ditemukan pada parasit non-manusia yang dapat membahayakan manusia dan primata non-manusia di Malaysia. Tinjauan pustaka mengenai studi cacing pada primata non-manusia yang hidup di alam liar, perkotaan, dan penangkaran Malaysia telah dilakukan pada tahun 2015-2022. Parasit-parasit yang berpotensi menimbulkan ancaman terhadap populasi primata non-manusia yang terancam punah dan penyakit zoonosis melalui penularan lintas spesies diidentifikasi lebih lanjut untuk dipelajari karakteristik, siklus hidup, dan metode pencegahannya. Lima penelitian telah ditinjau; empat spesies cacing telah diidentifikasi: Trichuris sp, Strongyloides sp, Ascaris sp, dan Enterobius sp. Trichuris memiliki prevalensi yang tinggi yaitu 2,2% hingga 86,6%. Sebagian besar parasit yang terdaftar ditularkan melalui jalur fecal-oral. Metode pencegahannya mencakup rutinitas kebersihan yang baik, sanitasi yang layak, pendidikan tentang kesehatan masyarakat, dan peningkatan status sosial ekonomi.

Judul: Struktur Kristal Film BaxSr1-xTiO3 dengan Variasi Fraksi Mol (x = 0,5 ; 0,6 ; 0,7 ; 0,8)
Abstrak: BaxSr1-xTiO (BST) film has been successfully made by growing BST on substrate surface Si (100) p-type with chemical solution deposition methode and spin coating technique at 3000 rpmrotational speed for 30 seconds. BST film made with mole fraction variation (x = 0,5 ; 0,6 ; 0,7 ; 0,8) and annealing process at a temperature of 850 °C for 22 hours. Characterization of BST samples obtained using X-ray diffractometer. The results of X-ray diffractometer characterization showed that the best crystal structure resulting in x = 0,5 mole fraction with the highest diffraction intensity and 25,55 nm crystal size, while the lowest diffraction intensity is owned by BST films with x = 0,8 mole fraction and the crystal size of 41,86 nm.
