Judul: Penilaian Pengetahuan Pemilik Kucing dan Staf Toko Hewan tentang Toksoplasmosis di Pet Lovers Centre dan Pet Integrity di Johor Bahru, Johor
Abstrak: Toxoplasmosis is a disease caused by the protozoan parasite Toxoplasma gondii (T. gondii). Toxoplasma gondii is a zoonotic parasite that causes a high prevalence of disease worldwide. Therefore, awareness raising and promotion of good preventive practices among pet shop staff and cat owners at the Pet Integrity (PI) and Pet Lovers Center (PLC) against toxoplasmosis is essential. The purpose of this study was to determine the level of knowledge of Toxoplasmosis among pet owners and pet shop staff in Johor Bahru, Johor. The study was designed with a cross-sectional study and data from 50 respondents were collected face-to-face using a Google form questionnaire. Data analysis was performed by using Chi- square test to examine the relationship between respondent's demographics and level of knowledge on toxoplasmosis. The data obtained were then analyzed descriptively by calculating the percentage of selected answers related to awareness and general knowledge about toxoplasmosis. The results showed that more than half (64%) of respondents from PLC and almost half (40%) of respondents from PI have a good level of knowledge. This study shows that gender, age, field of study, pet ownership, pet handling training among respondents did not have a significant relationship (p>0.05) with level and practice, however, the source of information obtained among respondents had a significant relationship (p<0.05) with the level of knowledge of toxoplasmosis. From this study, it is known that the overall level of knowledge and awareness of respondents about toxoplasmosis is included in the good category. Keywords: knowledge, pet shop, questionnaire, respondents, toxoplasmosis, Toksoplasmosis adalah penyakit yang disebabkan oleh parasit protozoa Toxoplasma gondii (T. gondii). Toxoplasma gondii merupakan parasit zoonotik penyebab penyakit yang tinggi di seluruh dunia. Oleh karena itu, peningkatan kesadaran dan promosi praktik pencegahan yang baik antara staf toko hewan dan pemilik kucing. Tujuan dari penelitian ini adalah untuk menilai tingkat pengetahuan Toksoplasmosis pada pemilik hewan peliharaan dan petugas pet shops di Johor Bahru, Johor. Penelitian dilakukan di dua toko hewan yaitu Pet Lovers Center (PLC) dan Pet Integrity (PI). Penelitian dirancang dengan studi cross- sectional dan data dari 50 responden telah dikumpulkan secara tatap muka menggunakan kuesioner Google form. Analisis data dilakukan dengan uji Chisquare untuk menguji hubungan antara demografi responden dan tingkat pengetahuan terhadap toksoplasmosis. Data yang diperoleh kemudian dianalisis secara deskriptif dengan menghitung persentase jawaban yang dipilih terkait kesadaran dan pengetahuan umum tentang toksoplasmosis. Hasil penelitian menunjukkan bahwa sekitar setengah lebih (64%) responden dari PLC dan hampir sebagian (40%) responden dari PI memiliki tingkat pengetahuan yang baik. Studi ini menunjukkan bahwa jenis kelamin, usia, bidang studi, kepemilikan hewan peliharaan, pelatihan penanganan hewan peliharaan di antara responden tidak memiliki hubungan yang nyata (p>0,05) dengan tingkat dan praktik, namun demikian sumber informasi yang diperoleh di antara responden memiliki hubungan yang nyata (p<0,05) dengan tingkat pengetahuan terhadap toksoplasmosis. Dari penelitian ini diketahui bahwa secara keseluruhan tingkat pengetahuan dan kesadaran responden tentang toksoplamosis termasuk dalam kategori baik.

Judul: Study of Animal Owners' Understanding of Protozoa Infection Cases in Cat Patients at Mayda Animal Care and iVet Clinic Dramaga
Abstrak: Infeksi protozoa gastrointestinal merupakan masalah utama pada hewan peliharaan, namun masih terabaikan khususnya di Indonesia. Infeksi protozoa gastrointestinal merupakan penyakit dengan gejala yang asimtomatik dan perlu diperhatikan karena penyebarannya yang cepat dan beberapa diantaranya bersifat zoonosis. Penelitian ini bertujuan mengetahui hubungan antara karakteristik responden terhadap tingkat pengetahuan, pemahaman, serta tindakan yang dimiliki terkait infeksi protozoa pada kucing. Penelitian ini juga bertujuan mempelajari kejadian infeksi protozoa pada pasien kucing di Mayda Animal Care dan iVet Clinic Dramaga periode Januari hingga Desember 2022. Pengambilan data dilakukan pada bulan September hingga Desember 2022, dengan merekap data rekam medik pasien kucing yang terinfeksi protozoa dan kuesioner untuk mengetahui tingkat pengetahuan, pemahaman, serta tindakan pemilik hewan terhadap infeksi protozoa. Berdasarkan hasil kuesioner, terdapat hubungan yang signifikan antara pendidikan terhadap tingkat pengetahuan dan pemahaman infeksi protozoa pada kucing. Berdasarkan data rekam medik, kasus infeksi protozoa lebih tinggi di Mayda Animal Care dibandingkan iVet Clinic Dramaga. Kasus tertinggi infeksi protozoa di Mayda Animal Care pada bulan Oktober, sedangkan iVet Clinic Dramaga pada bulan Agustus, Gastrointestinal protozoan infections are a major problem in pets, but are still overlooked, especially in Indonesia. Gastrointestinal protozoan infection is a disease with asymptomatic symptoms and needs attention because of its rapid spread and some of them are zoonotic. This study aims to determine the relationship between the characteristics of respondents and their level of knowledge, understanding, and actions related to protozoan infections in cats. This study also aims to study the incidence of protozoan infections in cat patients at Mayda Animal Care and iVet Clinic Dramaga from January to December 2022. Data collection was carried out from September to December 2022, by recapitulating medical record data of cat patients infected with protozoa and questionnaires to determine level of knowledge, understanding, and actions of animal owners towards protozoa infection. Based on the results of the questionnaire, there was a significant relationship between education and the level of knowledge and understanding of protozoan infection in cats. Based on medical record data, cases of protozoan infection are higher at Mayda Animal Care than iVet Clinic Dramaga. The highest case of protozoan infection at Mayda Animal Care was in October, while iVet Clinic Dramaga was in August

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
