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: Evaluasi Kesadaran Kesejahteraan Hewan di antara Penduduk Klang, Malaysia.
Abstrak: Animal welfare is a term that describes the potential measurable quality of live animals at a specific time, making it a scientific concept. The concept of animal welfare continues to evolve with the development of ethics, science, and politics. The Five Freedoms are internationally accepted standards of care that affirm every living being's right to humane treatment. This study aimed to evaluate the animal welfare awareness of Klang residents in Malaysia. A total of 200 samples were collected online using Google form-based questionnaire which was distributed through social media. The results were analyzed in descriptively for analysis ofthe association between demographic variables and the level of awareness about animal welfare the score was used ANOVA test. The result of the study revealedthat the level of animal welfare awareness among the respondents was in a good category. Among the four subgroups being studied, the differences in the level of animal welfare awareness were statistically insignificant. Only among the age and have heard or known animal welfare group, in freedom from hunger and thirst, the seniors (>60) have shown higher scores compared to teenagers and adults as well as those who have heard or known animal welfare have shown higher score compared to those who have not with significant differences among these groups., Kesejahteraan hewan adalah istilah yang menggambarkan potensi kualitas terukur dari hewan hidup pada waktu tertentu, Konsep kesejahteraan hewan terus berkembang seiring dengan perkembangan etika, ilmu pengetahuan, dan politik. Lima Kebebasan adalah standar perawatan yang diterima secara internasional , konsep tersebut menegaskan hak setiap makhluk hidup untuk diperlakukan secara manusiawi. Lima prinsip kebebasan terdiri dari, yaitu, bebas dari rasa lapar dan haus, bebas dari ketidaknyamanan, bebas dari rasa sakit, cedera dan penyakit, bebas dari rasa takut dan tertekan, dan bebas untuk mengekspresikan perilaku alamiahnya. Lima kebebasan memiliki dampak besar pada kesejahteraan hewan. Penelitian ini dilakukan untuk mengevaluasi tingkat kesadaran warga kota Klang Malaysia akan kesejahteraan hewan. Sebanyak 200 sampel dikumpulkan secara online menggunakan formulir Google yang disebarkan melalui social media (Facebook, Instagram). Hasil penelitian menunjukkan bahwa secara keseluruhan tingkat kesadaran warga Klang Malaysia terhadap kesejahteraan hewan berada pada kategori baik. Di antara tiga sub kelompok yang dipelajari, perbedaan tingkat kesadaran kesejahteraan hewan secara statistik tidak signifikan. Perbadaan skor yang signifikan hanya terjadi pada pengetahuan kebebasan dari rasa haus dan lapar saja dimana kelompok usia lanjut usia memiliki skor pengetahauan yang lebih tinggi dibanding dengan kelompok umur remaja dan dewasa serta mereka yang pernah mendengar atau mengenal kesadaran kesejahteraan hewan menunjukkan skor yang lebih tinggi dibandingkan dengan mereka yang tidak dengan perbedaan yang signifikan.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
