[Bahasa]: Pandemi COVID-19 berdampak pada berbagai aspek, termasuk kesehatan mental mahasiswa. Berbagai studi menunjukkan adanya peningkatan kejadian gangguan mental di masa pandemi. Gangguan mental terbanyak adalah depresi, kecemasan, dan stres. Pengetahuan kesehatan mental merupakan salah satu cara untuk menekan kejadian gangguan mental. Namun, data mengenai pengetahuan kesehatan mental terhadap gangguan mental pada mahasiswa masih terbatas. Oleh karenanya, peneliti mengadakan kegiatan edukasi melalui webinar daring untuk memberikan edukasi kesehatan mental yang mencakup penelitian untuk menganalisis tingkat pengetahuan kesehatan mental dan kejadian gangguan mental terbanyak, perbedaan keduanya berdasarkan aspek sosiodemografi, serta hubungan antara dua aspek tersebut pada mahasiswa di Indonesia selama pandemi. Data diolah menggunakan analitik komparatif dan korelasi dengan teknik pengambilan consecutive sampling. Respon diambil menggunakan kuesioner DASS-21 untuk mengetahui status psikologis responden dan 16 item pertanyaan yang telah diuji validitas dan reabilitas untuk mengetahui tingkat pengetahuan responden. Sebanyak 265 responden didominasi oleh jenis kelamin perempuan (81,5%), berusia 15 – 19 tahun (57,4%), dan berasal dari Jawa (62,3%). Sebagian besar responden memiliki tingkat pengetahuan depresi kurang (42,6%), kecemasan baik (61,9%), dan stres sangat baik (48,3%), dengan tingkat depresi normal (40,3%), kecemasan sedang (30,6%), dan stres sedang (27,2%). Hasil uji komparatif tidak ditemukan perbedaan signifikan pada variabel, kecuali tingkat pengetahuan kecemasan menurut kelompok usia (p=0,033). Uji korelasi Spearman Correlation menunjukkan tidak ada hubungan antara tingkat pengetahuan kesehatan mental terhadap tingkat depresi (p=0,250), kecemasan (p=0,819), dan stres (p=0,403). Kata Kunci: kesehatan mental, depresi, kecemasan, stres [English]: COVID-19 pandemic affects many aspects of human life, including college students’ mental health. Some studies showed increase on mental disorder in pandemic era. The most common mental disorders are depression, anxiety, and stress. Mental health knowledge is a means to suppress mental disorder. However, studies that concerned in mental health knowledge on mental disorder amongst college students are limited. Therefore, we held online webinar for mental health education, including a research aimed to analyze the most common mental health knowledge and disorder level, difference of both according to sociodemographic aspects, and correlation between those two aspects in college students during pandemic. All data was processed by using comparative and correlation statistical analytic with consecutive sampling. The instruments used were DASS-21 questionnaire to assess psychological status of respondents and another questionnaire with 16 items that had passed validity and reability tests to assess mental health knowledge. A total of 265 respondents were included, dominated by female (81.5%), aged 15 – 19 years old (57.4%), and from Java (62.3%). Most of respondents had less depression knowledge (42.6%), good anxiety knowledge (61.9%), very good stress knowledge (48.3%), normal depression level (40.3%), moderate anxiety (30.6%), and moderate stress (27.2%). The results of the comparative test show no significant difference on variables, except anxiety knowledge on age group (p=0.033). The result of Spearman Correlation show no correlation on mental health knowledge to depression level (p=0.250), anxiety level (p=0.819), and stress level (p=0.403). Keywords: mental health, depression, anxiety, stress

This research aimed to analyze the histopathology (tubular necrosis and proteinaceous casts) and renal function (SCr and BUN) differences of male Wistar strain white rats (Rattus norvegicus) after intravascular injection of iodinated contrast media Iohexol and Iopamidol. This research is an experimental laboratory with a post-test only control group design. Male Wistar rats that fit the criteria were divided into three groups by random sampling technique: Control (K), Treatment 1 (P1, Iohexol 350 mg iodine/mL), and Treatment 2 (P2, Iopamidol 370 mg iodine/mL). Iohexol and Iopamidol were injected at a dose of 1600 mg iodine/kg BW. The histopathology differences were observed under a light microscope with a magnification of 400x, which were analyzed semi-quantitatively through slides formed by the paraffin method and H&E staining. SCr and BUN levels were checked using an automatic analysis machine with blood samples taken through the cardiac ventricle. Kruskal-Wallis test (α= 0.05) on renal histopathology scores, both tubular necrosis and protein casts showed Asymp. Sig. value > 0.05, which means there is no significant difference between the groups (K, P1, and P2). Kruskal-Wallis test (α= 0.05) on SCr levels also showed the Asymp. Sig. value > 0.05 and One-Way ANOVA Comparative Test on BUN levels showed the Sig. value > 0.05 which means there is no significant difference in renal function between the groups. This study proved no difference in histopathology and renal function in Wistar rats after injection of iodinated contrast media Iohexol and Iopamidol.
