The freeze-thaw process in sperm cryopreservation generates reactive oxygen species (ROS) that impair motility, viability, and fertilizing capacity in fish, including the Javan barb (Systomus rubripinnis), an endemic Indonesian cyprinid of conservation concern. This study evaluated five natural antioxidants: basil leaf extract (BLE), noni fruit extract (NFE), moringa leaf extract (MLE), sambiloto leaf extract (SLE), and honey-egg yolk (HEY). Radical-scavenging capacity was measured by DPPH assay (IC₅₀: BLE 134.06, MLE 297.04, NFE 422.86, SLE 3010.46 ppm), and post-thaw motility, duration of motility, viability, abnormality, fertilization rate, and ATP bioluminescence were assessed. Optimum doses were 1% for BLE, NFE, and MLE, 1.25% for HEY, and 7% for SLE. BLE at 1% gave the best overall profile (motility 85.15 ± 0.88%; duration 7.14 ± 0.38 min; viability 82.21 ± 1.86%; abnormality 18.29 ± 0.16%), significantly exceeding the control (65.00 ± 2.31%; 4.56 ± 0.33 min; 68.00 ± 2.42%; 23.54 ± 0.28%; p < 0.05), whereas SLE sustained the longest motility. All extracts supported fertilization rates above 82% versus 70.08 ± 3.82% in the control, and 1% BLE preserved post-thaw luminescence equivalent to fresh sperm (165,217 vs. 164,087 RLU), interpreted comparatively. These plant-derived antioxidants are promising supplements for Javan barb germplasm conservation.

Video is one of the media that can be used in agricultural extension activities. However, often in practice, the video used is not in accordance with the tastes of farmers and has an impact on the effectiveness of the extension itself. This research was conducted with the aim of identifying the level of farmers' preference for 10 types of videos of rice cultivation extension and analyzing the attributes that affect the attractiveness of rice cultivation video counseling in Bunga Raya Village, Bunga Raya District, Siak Regency. The location selection was done purposively with the consideration that Bunga Raya Village, Bunga Raya District, Siak Regency had an active farmer group and had utilized video media in the extension activities. The sample in this study consisted of 100 farmer panelists to assess the level of preference for the video and 12 expert panelists in attribute assessment. The hedonic test analysis was used to identify the level of farmers' preference for the 10 types of video extension of rice mina cultivation and descriptive test to analyze the attributes that affect the attractiveness of rice video extension education. The results of cluster analysis (AHC) from the hedonic test and Principal Component Analysis (PCA) analysis of the descriptive test are then analyzed using preference mapping techniques. The best video of this study is video number 1 with a respondents' favorite level of 89% and produces a video attribute rating of the most influential namely educational material, understanding material, appropriate material, material to make it easier, story, duration, tested material, gradual material, audio, color, visual, transition, zoom, movie, layout design, back sound, typography, narration, sound effects, video effects, animation, and dialogue. So that preference mapping is very helpful in developing new products by providing a more distinctive visual assessment of hedonic and descriptive data

Background: The learning process of biology does not only promote discovery but also a process of discovery by being able to increase scientific attitudes. In addition, the selection of a learning model is very influential on success in learning. Inquiry learning emphasizes critical thinking and analysis to find the answer to a question in question. Therefore, this study aims to analyze the effect of the Guided Inquiry learning method on the ability to use scientific methods. Methods: Quasi-experimental with the sampling technique using simple random sampling. A multiple-choice test totalling 18 questions was used as an instrument. The research data were analyzed using the Mann U-Withney non-parametric statistical test. Results: The test results obtained that the calculated Z value of 6.8 is greater than the Z table value (0.05) of 1.96. Conclusions: there is an effect of using the Guided Inquiry learning model on the ability to use scientific methods of class X students at SMA Negeri 2 Karawang.

The freeze–thaw process in sperm cryopreservation generates reactive oxygen species (ROS) that impair motility, viability, and fertilizing capacity in fish, including the Javaen barb (Systomus rubripinnis), an endemic Indonesian cyprinid of conservation concern. Cryopreservation underpins gene bank development for aquatic genetic resources and supports biodiversity conservation alongside hatchery-based stock enhancement. This study evaluated five natural antioxidants: basil leaf extract (BLE), noni fruit extract (NFE), moringa leaf extract (MLE), sambiloto leaf extract (SLE), and honey–egg yolk (HEY). Each antioxidant was supplemented into the Kurokura’s cryopreservation extender across a graded concentration series (BLE 1–4%, NFE and MLE 0.5–1.5%, SLE 6–9%, and HEY 1–2% with a fixed 5% egg yolk) and compared with an antioxidant-free control. Radical scavenging capacity was measured by DPPH assay (IC₅₀: BLE 134.06, MLE 297.04, NFE 422.86, SLE 3010.46 ppm), and post-thaw motility, duration of motility, viability, abnormality, fertilization rate, and ATP bioluminescence were assessed. The most effective doses tested were doses of 1% for BLE, NFE, and MLE, 1.25% for HEY, and 7% for SLE. BLE at 1% gave the best overall profile (motility 85.00 ± 0.88%; duration 7.14 ± 0.38 min; viability 82.00 ± 1.86%; abnormality 18.26 ± 0.16%), significantly exceeding the control (65.00 ± 2.31%; 4.56 ± 0.33 min; 68.00 ± 2.42%; 23.54 ± 0.28%; p < 0.05), whereas SLE sustained the longest motility. All extracts supported fertilization rates above 82% versus 70.08 ± 3.82% in the control, and 1% BLE preserved post-thaw luminescence equivalent to fresh sperm (165,217 vs. 164,087 RLU), interpreted comparatively. These locally available, plant-derived antioxidants offer a low-cost route to germplasm conservation of Javaen barb, strengthening conservation hatchery and broodstock management, sustainable aquaculture production, and food security for inland fisheries communities.
