Judul: Implementasi VRML pada Media Pembelajaran Geometri untuk Sekolah Dasar dengan Menggunakan Metode Pembentukan Objek Ekstrusi
Abstrak: Some students have difficulty when learning geometry. It is because imagining, designing, and describing a geometric object requires high imagination or abstraction to understand it. This research implements the formation of extruded object method on VRML. The method is used to build and visualize a variety of geometric object model. The research built a web-based system. It can assist students for studying the shape of geometric objects. The research was conducted in several stages which adapted from waterfall model. The results of testing system and questionnairing to some respondents indicated functions on the system run well and the level of system usability was good. The results of extrusion method were more varied than primitive models. Surface texture of ball, cone, and tube which used extrusion method were smoother than primitive models.

Judul: Kajian Literatur Sistematik Penggunaan Teknologi Virtual Reality dalam Implementasi Pembelajaran Pertanian dan Perikanan
Abstrak: Studi ini menganalisis penelitian sebelumnya mengenai aplikasi untuk pembelajaran pertanian dan perikanan. Metode penelitian yang digunakan adalah kajian literatur sistematis dengan menggunakan Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Hasil penelitian menunjukkan bahwa materi pembelajaran dan desain elemen metaverse masih belum optimal. Masih terdapat celah implementasi antara teknologi imersif yang sedang dikembangkan saat ini dengan konsep metaverse. Oleh karena itu, perencanaan jangka panjang dan studi kasus penggunaan metaverse dalam pendidikan harus dilakukan lebih baik atau lebih matang lagi. Kekurangan ini menjadi poin penting untuk penelitian selanjutnya dalam pengembangan metaverse untuk pendidikan di bidang pertanian dan perikanan. Peneliti berharap studi ini mampu memberikan pengetahuan tentang teknologi metaverse kepada pendidik agar dapat membuat keputusan yang lebih tepat dalam memanfaatkannya di lembaga pendidikan., This study analyzes previous research regarding applications for learning agriculture and fisheries. The research method used is a systematic literature review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The research results show that the learning materials and metaverse element design are still not optimal. There is still an implementation gap between the immersive technology currently being developed and the metaverse concept. Therefore, long-term planning and case studies on the use of metaverse in education must be done better or more maturely. This deficiency is an important point for further research in developing a metaverse for education in agriculture and fisheries. Researchers hope that this study is able to provide knowledge about metaverse technology to educators so they can make more informed decisions in utilizing it in educational institutions.

Judul: Dog Ticks Infestation and Its Correlation to Tick-Borne Diseases.
Abstrak: Ticks infestation on dog could lead to itchiness, anemia, skin disorders, and tick-borne diseases, such as Ehrlichiosis, Babesiosis, Anaplasmosis and Rocky Mountain Spotted Fever. Besides dogs, Ehrlichiosis were known to be zoonotic. Pre-mature stage tick life cycle that occur outside its host, will enhance contacts between ticks and human. The study of ticks infestation and tick-borne diseases on the dog is necessary, because it has not a lot of information about the diversity, prevalence and degree of ticks infestation in Indonesia. Ticks survey, included ticks sampling and dogs blood test were performed at Animal Police Directorate Security Agency (Baharkam) and Atang Sendjaja Air Force (ATS). Meanwhile ticks sampling also data of cases of ticks infestation and diseases transmitted obtained from 21 veterinary clinics in Bogor, Jakarta and Bandung. All ticks samples stored in bottles containing 70% alcohol for identification. Blood tests performed for Ehrlichiosis, Babesiosis and Anaplasmosis diagnosis. The identification results of the 950 ticks samples that obtained from 97 dogs of Baharkam, ATS and veterinary clinics in Bogor, Jakarta and Bandung, showed only one ticks species, Rhipicephalus sanguineus. This ticks belong to three-host tick, which require three hosts to complete its life cycle. Each ticks stage need a host, either same dog (if it is in place there is only one or a few dogs), as well as different dogs. Research in Baharkam conducted on 81 dogs (53 males and 28 females). The prevalence of dogs infested by ticks was 67.90%. The percentage of male dogs that infested by ticks are larger (69.81%) than female (64.29%). Based on Chi-Square test, there was no relationship between sex and breed of dog with degree of ticks infestation. Generally dogs infested with mild infestation category (41.98%), meanwhile moderate category was 18.52%, 2.47% high and 4.94% very high. The dog’s body region that the most infested by R. sanguineus was dog's back. Probably these body regions were be preferred because they are less accessible for the dog to remove them with its paws. Collection of ticks with tick-drag on Baharkam grass field showed positive results on the field that was more often used to practice by dogs. The samples that obtained was larvae stage ticks with density 152 larvae on 215m2 area of the field. Adult stage ticks and several adult females which laying eggs on the cage wall were obtained in the dog kennels. Whole of male and female ATS dogs infested with ticks (14 dogs). In general, dogs infested with very high infestation category was 64.29%, compared by high degree category (21.43%) and moderate (14.29%). Ticks predilection were found mostly on the dog’s head – neck. On ATS grass field did not reveal any ticks, but positively inside the kennels. It happens probably because dogs are rarely released from the kennel, so that the ticks was did drop-off inside the kennel. The total cases of ticks infestation of dogs at Bogor, Jakarta and Bandung veterinary clinics in 2008 until June 2013 as many as 731 cases. In general, there was an increases of the ticks infestation prevalence at three cities in that range
