Mathematics Learning Within Culture And Nation Character: Using Traditional Dance In Learning The Concept Of Symmetry At Grade IV Primary School

This paper introduces a new approach in mathematics learning within culture and nation character. Indonesian traditional dances are used as a context in learning the concept of symmetry. Using context as a starting point in learning processes is the major concern in Realistic Mathematics Education (RME), one of the innovations in mathematics teaching developed in the Netherlands. Adapted to Indonesian culture, this approach is called Pendidikan Matematika Realistik Indonesia (PMRI). This approach is used to combine the so-called math traditional dances with mathematics learning. This can be seen as building nation character in appreciating Indonesian traditional culture. Design research is used in research methodology. This research was conducted to 22 students in grade IV at MIN 2 Palembang. The result shows that within the use of culture and nation character in learning mathematic can improve students’ understanding of the concept of symmetry. Besides, students can optimize cultural values which indirectly showed in learning process such as accuracy, perseverance, hard work, curiosity, and unyielding attitude. Key Words: PMRI, design research, math traditional dance, symmetry, nation character

Tinjauan Molekuler dan Epidemiologi Mutasi pada Virus SARS-CoV-2

Abstract. The SARS-CoV-2 virus which is the cause of the COVID-19 pandemic since the end of 2019 has undergone many mutations that gave rise to several variants of concern (VOC) with higher transmission, virulence, and ability to evade the immune system than the initial variant (wild-type). Until now, there are four variants included in the VOC of the virus, namely alpha, beta, gamma and delta variants. The increased transmission and virulence of these VOCs were associated with mutational changes in the spike protein, which is the structure of the virus that plays a role in binding to host cells. In this article, we conduct a literature review on VOCs from the SARS-CoV-2 virus related to mutations that occur and their impact on the viral binding process. To gain an understanding of the impact of mutations in these variants, we also reviewed the structure of the spike protein and the process of viral entry into host cells. Keywords: viral mutation, variants of concern (VOC), COVID-19, SARS-CoV-2

Sindroma Laurence-Moon-Bardet-Biedl

ABSTRACT: A 10-year old Javanese boy suffering from Laurence-Moon-Bardet-Biedl Syndrome characterized by retinitis pigmentosa, myopia, polydactily, obesity, hypogenitalism and mental retardation has been reported. Family history showed that one of his brothers had also the same abnormalities, while his two other brothers as well as his parents were perfectly normal. The possibility of the transmission of this disease was X -linked recessive. For this patient, a comprehensive management by ophthalmologists, paediatricians, psychiatrists and surgeons was necessary. Special education was needed to handle his mental retardation and his visual disturbances, and genetic counseling was necessary for the patient and his family. Key Words: Laurence-Moon-Bardet-Biedl Syndrome - X-linked recessive gene - genetic counseling - retinitis pigmentosa - myopi

Teknologi Pengembangan Vaksin Berbasis Vektor Adenovirus

Teknologi pembuatan vaksin telah berkembang pesat terutama dalam hal metode penghantaran antigen ke dalam tubuh manusia atau pun hewan yang divaksinasi. Salah satunya adalah penggunaan vektor virus. Keunggulan vaksin yang menggunakan teknologi ini adalah tidak memerlukan tambahan adjuvant dalam administrasinya seperti halnya vaksin sub-unit protein. Selain itu juga memiliki kemampuan menginduksi respon imun seluler di samping respon imun humoral. Salah satu vektor virus yang telah banyak digunakan adalah adenovirus. Dalam sebuah studi kami menggunakan vektor human adenovirus serotipe 5 (Ad5) untuk membawa materi genetik parasit malaria yang berasal dari protein yang terletak di permukaan stadium sporozoite (sirkumsporozoit). Antigen yang dimasukkan ke dalam vektor virus adalah chimera dari dua strain Plasmodium vivax, yaitu VK210 dan VK247. Hasil pemeriksaan immunostaining menunjukkan bahwa adenovirus yang membawa antigen chimera tersebut dapat menginduksi ekspresi kedua protein pada kultur sel HEK 293A. Dengan demikian dapat disimpulkan bahwa vaksin malaria vivax berbasis vektor Ad5 dalam studi tersebut memiliki kemampuan dalam transduksi sel mamalia, yang merupakan syarat penting untuk uji coba lanjutan pada hewan coba. Adenovirus telah digunakan dalam uji coba vaksin malaria falciparum pada manusia dan juga dalam beberapa kandidat vaksin untuk COVID-19 yang dikembangkan di China dan Inggris
