Judul: Kesadaran Masyarakat terhadap Vaksinasi Hewan Peliharaan di Kota Puchong, Malaysia
Abstrak: Pets vaccination is important in preventing fatal and infectious diseases and reduce spreading of zoonotic diseases such as Rabies. Vaccination is done by injecting vaccines to trigger immune responses in the host. The aim of the study is to evaluate the awareness of community in Puchong city, Malaysia towards pets vaccination by measuring knowledge, attitude and practice level of immunization. The research was conducted through online survey using questionnaires in Google forms and distributed through social media such as Whatsapp and Facebook. The sample size was determined using 95% confidence level, 50% expected proportion, and accepted error level of 10%, so that a minimum sample size of 97 samples was obtained. A total of 267 respondents living in Puchong city were collected in the online survey. The data obtained were analyzed using the Chi-Square Test and Gamma Correlation Test to examine the relationship and strength of the correlation between characteristics, knowledge, attitude and practice of respondents towards vaccination. The results showed that the level of knowledge, attitude and practice of respondents were in good category. In this study, there was a significant relationship (p<0.05) and a weak correlation (0.10≤r≤0.29) between age and practice, education level and knowledge, education level and attitude, area and attitude, as well as pet ownership and attitude. This study shows that there is a significant relationship (p<0.05) and a moderate correlation (0.30≤r≤0.49) between knowledge, attitude and practice of respondents towards vaccination., Vaksinasi hewan peliharaan penting untuk mencegah penyakit yang fatal dan menyular serta mengurangi penyebaran penyakit zoonotik seperti Rabies. Vaksinasi dilakukan dengan menyuntikkan vaksin untuk memicu respons imun pada inang. Tujuan penelitian adalah untuk mengevaluasi kesadaran masyarakat di kota Puchong, Malaysia terhadap vaksinasi hewan peliharaan dengan menilai tingkat pengetahuan, sikap dan perilaku imunisasi. Penelitian dilakukan melalui wawancara secara daring menggunakan kuesioner dalam Google form dan disebarkan melalui media sosial seperti Whatsapp dan Facebook. Besaran sampel ditentukan menggunakan tingkat kepercayaan 95%, proporsi dugaan 50%, dan tingkat kesalahan 10%, sehingga diperoleh besaran sampel minimum sebanyak 97 sampel. Sejumlah 267 responden yang tinggal di kota Puchong dikumpulkan dalam wawancara daring tersebut. Data yang diperoleh dianalisis menggunakan Chi-Square Test dan Gamma Correlation Test untuk menguji hubungan serta kekuatan korelasi antara karakteristik, pengetahuan, sikap dan perilaku responden terhadap vaksinasi. Hasil penelitian menunjukkan bahwa tingkat pengetahuan, sikap dan perilaku responden berada dalam kategori baik. Dalam penelitian ini didapat hubungan yang nyata (p<0,05) dan korelasi yang lemah (0,10≤r≤0,29) antara usia dan perilaku, tingkat pendidikan dan pengetahuan, tingkat pendidikan dan sikap, daerah dan sikap, serta kepemilikan hewan peliharaan dan sikap. Penelitian ini menunjukkan bahwa ada hubungan yang nyata (p<0,05) dan korelasi yang sedang (0,30≤r≤0,49) antara pengetahuan, sikap dan perilaku responden terhadap vaksinasi.

Judul: Kesejahteraan hewan peliharaan dalam ruangan dan hewan peliharaan luar ruangan di Seri Petaling, Kuala Lumpur, Malaysia
Abstrak: Animal welfare is a broad and multi-faceted topic that refers to the accountability of human towards animal well-being. Animal welfare has been receiving growing recognition worldwide that the public should be aware of. In Malaysia, animal welfare issue especially animal cruelty often gets highlighted and attracts media attention. The study of animal welfare awareness based on the “Five Freedoms” mainly in pet animal is underexplored in Malaysia. This study was carried out to evaluate animal welfare awareness of residents in Seri Petaling and the relationship across the subgroups such as fields of study, age categories and religion status. A total of 349 samples were collected online via the dissemination of questionnaire through Google form. Overall, the level of animal welfare awareness specifically in companion animal of the respondents is in medium category. Among the five freedoms being studied, the differences in the level of animal welfare awareness between three types of pet owners were statistically significant. However, among the age and religious categories, the differences in the level of animal welfare awareness were statistically insignificant., Kesejahteraan hewan adalah topik lintas disiplin yang luas. Kesejahteraan hewan adalah tanggungjawab manusia terhadap hewan yang penerapannya telah berlaku universal. Oleh karena itu, masyarakat harus memiliki kesadaran terhadap penerapannya. Di Malaysia, masalah kesejahteraan hewan khusus kekejaman terhadap hewan sering disorot dan menarik perhatian media. Penelitian tentang tingkat kesadaran masyarakat terhadap kesejahteraan hewan berdasar prinsip "Five Freedoms" terutama pada hewan peliharaan sangat terbatas di Malaysia. Penelitian ini bertujuan mempelajari kesadaran kesejahteraan hewan dan mengevaluasi hubungan subkelompok seperti bidang studi, kategori usia dan status agama dengan tingkat kesadaran kesejahteraan hewan dari warga di Seri Petaling. Data dari 349 responden dikumpulkan secara online melalui penyebaran kuesioner formulir Google. Secara keseluruhan, tingkat kesadaran responden terhadap kesejahteraan hewan peliharaan tergolong kategori sedang. Dari lima kebebasan yang diteliti, ditemukan perbedaan yang nyata secara statistik dalam kesadaran kesejahteraan hewan diantara pemilik hewan dari ketiga cara pemeliharaan tersebut. Namun, antara kelompok umur dan agama, perbedaan tingkat kesadaran kesejahteraan hewan secara statistik tidak signifikan.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
