“…Plankton abundance is a useful tool for determining the fertility level of the waters in the research area. The presence of garbage contaminates the aquatic ecosystem since it lowers the water's quality and, in particular, the diversity of plankton [42]. The research site is used for brackish water aquaculture, particularly shrimp cultivation, in addition to industrial area activities.…”

North Aceh Regency and Lhokseumawe City’s waters are mangrove ecosystems, estuaries, fisheries management activities, and industrialization activities. Activities in the industrial areas of North Aceh Regency and Lhokseumawe City have the ability to contaminate waters and affect the chemical and physical composition of the water, which has a direct impact on the abundance of harmful bacteria (Vibrio sp). The study looked at the distribution of harmful bacteria (Vibrio sp) in water near industrial areas in North Aceh Regency and Lhokseumawe City. The purpose of this study is to investigate the abundance of pathogenic bacteria (Vibrio sp.) in the waterways of North Aceh Regency and Lhokseumawe City's industrial areas. This study will also look into the relationship between water quality factors and the abundance of harmful bacteria. The study was carried out in July and August 2023 at four stations placed in marine waters near the industrial area. The research methods used in this research are survey methods and laboratory analysis. Purposive sampling and the ANOVA test were the analysis and sampling techniques employed in this study. The findings demonstrated that there was no discernible variation in Vibrio parahaemolyticus between stations 1, 2, 3, and 4. Station 2 saw a strong Vibrio cholerae effect (p > 0.05), resulting in 87.20 74.36b CFU/ml. Vibrio total from the four research stations that significantly affected station 2 (p > 0.05) were 280.00 167.26b CFU/ml.

“…Aspek kegrafisan terdiri dari enam indikator, yaitu jenis dan ukuran huruf yang digunakan jelas dan mudah dibaca oleh siswa, ketepatan penggunaan dan kemenarikan video, layout atau tata letak, cover, link, tampilan tes mandiri, dan post-test mendapatkan kategori baik. Penggunaan jenis huruf yang baik adalah salah satu unsur penting yang membuat pesan dan materi dalam E-Module tersampaikan dengan jelas, melalui pengemasan video dalam E-Module, diharapkan siswa akan memperoleh pengalaman belajar yang berbeda saat mereka membaca, mendengar, dan memungkinkan untuk melaksanakan praktik sederhana (Ernica & Hardeli, 2019;Safnowandi, 2019). Hasil analisis dari reliabilitas E-Module interaktif oleh 5 orang validator berdasarkan hasil perhitungan dari ICC yaitu baik.…”

This research aims to develop an interactive E-Module on Kingdom Monera material. The research method used is R&D (Research & Development) using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The data source for this research is 15 students consisting of class X Science 3 at SMA Negeri 9 Pontianak who were selected using the technique random sampling by lottery. The research instruments used were content validation sheets and student response questionnaires. Validation was carried out by five validators, namely Lecturers in the Biology Education Study Program, Faculty of Teacher Training and Education, Tanjungpura University, and 4 Biology Teachers from SMA Negeri 7 Pontianak, SMA Negeri 9 Pontianak, SMA Negeri 11 Pontianak, and MA Negeri 1 Pontianak, and analyzed using Aiken's V to knowing the validity of the content, as well as the Interclass Correation Coefficient to determine reliability. Validation is carried out by filling out a questionnaire sheet regarding four aspects, namely appropriateness of content, language, presentation and graphics. The ICC reliability results were 0.824 and the Aiken's V validity was 0.93, fulfilling the very good category. Meanwhile, students' responses used three aspects, namely aspects of cognition, affection and conation. In the cognitive aspect, the average was 85.42, the affection aspect was 86.00 and 87.50. From these three aspects, an overall average of 86.31 was obtained in the good category. It can be concluded that the interactive E-Module on Kingdom Monera material is suitable for use in the learning process.

Lempuk fish is a native Indonesian fish that is endemic in the Ranu Grati tectonic lake, Pasuruan Regency, East Java. This research aims to provide information in efforts to domesticate lempuk fish, especially on reproductive aspects related to the microscopic characteristics of gonads and reproductive type of Lempuk fish (Gobiopterus sp). This research uses the primary sexual characteristics method with gonadal histology. The variables observed included the male to female sex ratio, the histological structure of male and female gonads, and the reproductive type of lempuk fish. All data was analyzed descriptively, qualitatively and quantitatively by comparing with related literature. The samples taken in this research were 39 Lempuk Fish (Gobiopterus sp). The samples were then preserved in 10% formalin. The number of samples for histological analysis was 20 individuals, while for morphometric and meristic analysis there were 8 individuals. The results of the research show that morphologically the lempuk fish has a transparent body shape and there is a central line on the body with black or brown pigment and has a total length of around 2-3 cm. Lempuk fish have a type of reproduction that develops asynchronously (asynchronous) because the development of oocytes in the ovaries of female fish shows a variety of developmental stages, namely the initial growth stage (nuclear and perinuclear chromatin), cortical alveolar, vitellogenesis, and the mature stage. The sex ratio is predominantly female with a ratio of 0.64: 0.36. The histological structure of male and female gonads has histological differences that reflect different reproductive functions, where the ovaries play a role in egg cell production, while the testes are responsible for sperm formation. An imbalance in the sex ratio indicates the importance of carrying out domestication steps in order to prevent extinction or continuous population decline.
