Teh kombucha memiliki aktivitas antibakteri pada bakteri Gram negatif, Gram positif, dan bakteri yang resisten terhadap antibiotik. Methicillin-resistant Staphylococcus aureus (MRSA) merupakan salah satu strain bakteri Staphylococcus aureus yang sudah mengalami resistensi terhadap antibiotika. MRSA merupakan penyebab utama infeksi nosokomial dan berbagai sindrom klinik. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri teh kombucha dan mengetahui perbedaan daya antibakteri teh hitam kombucha dan teh hijau kombucha dalam menghambat MRSA. Kombucha teh hitam dan kombucha teh hijau dibuat dengan fermentasi cair. Uji antibakteri teh kombucha pada MRSA dilakukan dengan metode difusi sumuran. Perbedaan antibakteri teh hitam kombucha dan teh hijau kombucha dianalisis menggunakan uji-t. Teh hijau kombucha memiliki kadar asam total yang lebih tinggi dengan pH yang lebih rendah dibandingkan teh hitam kombucha. Teh hitam kombucha dan teh hijau kombucha mempunyai aktivitas antibakteri pada MRSA yang ditunjukkan dengan terbentuknya zona irradikal dengan diameter 14 ± 0,85 mm dan 17,1 ± 0,93 mm. Zona irradikal menunjukkan aktivitas teh hitam kombucha dan teh hijau kombucha dikategorikan lemah. Oleh karena itu, teh kombucha belum efektif sebagai antibakteri terhadap MRSA. Hasil uji-t menunjukkan terdapat perbedaan aktivitas antibakteri antara teh hitam kombucha dan teh hijau kombucha pada Methicillin-resistant Staphylococcus aureus (MRSA).

Karbon tetraklorida (CCl4) merupakan senyawa kimia yang bersifat toksik, namun masih sering digunakan dalam industri bahan pendingin, alat pemadam kebakaran, dan pestisida. Penggunaan CCl4 secara terus menerus dapat memicu terbentuknya radikal bebas sehingga berpotensi merusak organ hati dan ginjal. Tanaman sirsak (Annona muricata L.) salah satu tanaman yang dapat digunakan sebagai obat alternatif karena mengandung senyawa antioksidan yang dapat mencegah pembentukan radikal bebas. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak daun sirsak terhadap gambaran histologi hati dan ginjal mencit (Mus musculus L.) yang diinduksi karbon tetraklorida. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 24 ekor mencit jantan yang dikelompokkan menjadi 4 perlakuan yaitu kontrol negatif (K-) diberi larutan Na-CMC 0,5%, kontrol positif (K+) diinduksi CCl4 0,007 mL/20g BB yang dilarutkan dalam minyak kelapa 0,1 mL, dan dua perlakuan yang diinduksi CCl4 0,007 mL/20g BB serta diberi ekstrak daun sirsak dosis 100 mg/kg BB (P1) dan 200 mg/kg BB (P2). Parameter yang diamati pada histologi hati yaitu degenerasi melemak, degenerasi hidropik, nekrosis, kongesti, serta infiltrasi sel radang. Parameter yang diamati pada histologi ginjal yaitu degenerasi melemak, nekrosis, infiltrasi sel radang, dan pembengkakan glomerulus. Hasil penelitian menunjukkan terjadi penurunan kerusakan yang berbeda nyata (p<0,05) pada P1 dan P2 dibandingkan dengan kontrol positif (K+) pada sayatan histologi hati dan ginjal, sehingga dapat disimpulkan bahwa pemberian ekstrak daun sirsak mampu memperbaiki kerusakan hati dan ginjal setelah diinduksi karbon tetraklorida.
四氯化碳(CCl4)是一种毒性化合物，但在冷却、灭火器和杀虫剂行业仍经常使用。持续使用CCl4会引发自由基的形成，对肝脏和肾脏造成潜在的损害。蓟是一种可以作为替代药物的植物，因为它含有一种抗氧化剂，可以防止自由基的形成。这项研究的目的是确定刺痛叶提取物对小肠和肾脏组织造影的影响。这项研究使用随机设计,配有24尾巴的雄鼠分为4负控制(K -)待遇得到溶液Na-CMC 5%,积极控制(K +) CCl4诱导0.007 mL - 20g BB椰子油中溶解的0.1 mL,两CCl4诱导的待遇0.007 mL - 20g BB和被酸叶提取物剂量100毫克/公斤(BB (P1)和200毫克/公斤(BB (P2)。肝脏组织观察到的参数包括软化、水样退化、坏死、结膜和炎症细胞渗透。肾脏组织观察到的参数包括退行性变液、坏死、炎症细胞渗透和球状肿胀。研究表明，P1和P2的损伤明显减少(p< 0.05)与肝脏和肾脏组织切口的正控制(K+)相比，从而得出结论，刺痛剂提取物在诱导四氯化碳后能够修复肝脏和肾脏的损伤。

Produk daging olahan adalah salah satu jenis pangan yang mudah mengalami kerusakan. Kerusakan pada produk daging olahan diakibatkan karena adanya pertumbuhan mikroorganisme. Menanggulangi hal tersebut, perusahaan pengolahan daging banyak menambahkan bahan tambahan pangan (BTP) yaitu natrium nitrit (NaNO2). Akumulasi nitrit yang berlebih dalam tubuh dapat menimbulkan efek yang merugikan pada sistem reproduksi. Penelitian oleh Pavlova et al. (2017) menemukan terjadi penurunan berat epididimis dan pengurangan jumlah spermatoa tikus yang diberi paparan NaNO2 tinggi. Rumput laut Eucheuma cottoni mengandung antioksidan yang dapat menetralkan sifat oksidatif yang ditimbulkan oleh NaNO2. Penelitian ini dilakukan untuk mengetahui pengaruh ekstrak rumput laut Eucheuma cottoni terhadap kadar Malondialdehid (MDA) dan spermatozoa pada tikus putih (Rattus norvegicus L.) jantan yang diinduksi NaNO2. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari kontrol negatif (K-), kontrol positif (K+), perlakuan dosis 1 (P1), perlakuan dosis 2 (P2) dan perlakuan 3 (P3). Kontrol negatif (K-) diberikan aquades sedangkan kontrol positif diberikan natrium nitrit dosis 22,5 mg/kg BB. Perlakuan dosis 1,2 dan 3 diberikan metode kombinasi natrium nitrit dan ekstrak rumput laut dosis 150 mg/kgBB/hari (P1), 300 mg/kgBB/hari (P2), dan 450 mg/kgBB/hari (P3). Pemberian perlakuan dilakukan selama 45 hari. Adapun variabel penelitian terdiri dari kadar MDA (Malondialdehid) pada serum dan kualitas spermatozoa meliputi integritas membran, viabilitas, motilitas dan morfologi spermatozoa dari tikus putih jantan. Analisis data dilakukan melalui uji statistik One Way Anova dan dilanjutkan dengan uji Duncan. . Hasil penelitian menunjukkan ekstrak rumput laut dosis 150 mg/kgBB mampu menurunkan kadar MDA (Malondialdehid), meningkatkan motilitas, viabilitas, integritas membran dan morfologi spermatozoa secara signifikan.

The application of the Virtual Field Trip method plays a role in providing opportunities for students to be independent in their learning outside the classroom while increasing student motivation, reducing student stress; The important combination of these positive factors allows conceptual learning in Biology especially on biodiversity materials to be more effective in pandemic conditions. The purpose of implementing VFT is to replace conventional field trips, and introduce students to various aspects that are not easy to study directly for safety reasons, such as steep valleys and cost efficiency. Augmented Reality (AR) technology can incorporate 3D objects into a real environment. Biodiversity learning must involve students actively and use the surrounding environment as a learning resource with the ultimate goal of which is to increase literacy in biodiversity conservation. This is because biodiversity conservation literacy is included in scientific literacy which requires objective observation so as to encourage one's ability to understand various biodiversity, conservation efforts and communicate and apply conservation knowledge to solve problems that related to biodiversity issues

We used a descriptive method which consisted of two stages, namely instrument and learning medium validation. The instrument was validated by two validators who were lecturers in Study Program of Biology Education of Tanjungpura University (Untan). The flipbook medium was validated by five validators consisting of two lecturers from Study Program of Biology Education and three biology teachers from three different high schools in Pontianak City. The instrument sheet consisted of three aspects and twelve criteria. Data were analyzed using content validity ratio (CVR) and content validity index (CVI) by Lawshe (1975). The results of flipbook media validation showed that all criteria obtained a CVR value of 0.99, therefore, the CVI value obtained was also 0.99. So, it can be concluded that the flipbook is declared valid and can be used as a learning medium for the Material of Growth and Development in the twelfth grade of SMA / MA.
本研究旨在通过对鲤(Cyprinus carpio L.)在人工饲料下的生长速率观察，说明flipbook作为SMA/ MA 12年级生长发育材料学习介质的可行性。我们采用描述性方法，分为两个阶段，即仪器验证和学习介质验证。该仪器由丹戎普拉大学(Untan)生物教育研究项目的两名讲师进行验证。flipbook媒介由五名验证者进行验证，包括来自生物教育研究计划的两名讲师和来自Pontianak市三所不同高中的三名生物教师。量表包括三个方面和十二个标准。数据采用Lawshe(1975)的内容效度比(CVR)和内容效度指数(CVI)进行分析。flipbook介质验证结果显示，所有标准的CVR值均为0.99，因此得到的CVI值也为0.99。因此，可以得出结论，flipbook被宣布有效，可以作为SMA / MA十二年级的生长与发展材料的学习媒介。
