Persepsi Masyarakat Nelayan Sondong Terhadap Alat Tangkap Sondong di Daerah Sungsang Banyasin Sumatera Selatan
fisheries are the mainstay of the coastal community's economy, and Sondong fishing gear is still commonly used. Although Sondong is considered effective, it raises ecological concerns because it risks damaging the seabed habitat and produces high bycatch. This study aims to describe fishing communities' perceptions of Sondong fishing gear regarding its effectiveness and impact on fish resources and the environment. The study employed a quantitative descriptive approach with purposive sampling of active fishermen in Sungsang, conducted in November 2024. The results show that fishermen have a strong understanding of Sondong because it has been widely used and passed down informally. They perceive Sondong as an effective and profitable tool, though this perception is changing as catches decline. The ecological impact has not been widely recognized, and regulations tend to be rejected due to economic dependence. As fishermen's perceptions are more oriented toward the economy than ecology, an educational approach is needed to encourage the transition to more sustainable fishing gear.

Kesadaran Masyarakat Dalam Mengurangi Bencana Banjir Dilihat Dari Aspek Hukum Di Sumatera Selatan
Indonesia is a country that is prone to disasters. Based on BNPB data, from 2018 to 2019 there were 3,999 disasters. The total potential area of ​​flood hazard in South Sumatra Province as a whole is 6,476,932.00 Ha and is in the High class. The extent of flood hazards is broken down into 3 hazard classes. In reality, the survey results show that knowledge of disasters in Indonesia is still not accessible to the general public. There is a gap between disaster knowledge and existing knowledge at the community level. This is proven by the community's lack of responsiveness in protecting the surrounding environment, their lack of response to natural phenomena and their tendency to wait for the government to handle disasters. The success of this strategy is expected to increase public awareness of disasters so that they actively participate in flood prevention. The data collection technique used is in the form of a questionnaire or questionnaire. The results show that children who have environmental awareness in Plaju District are only around 50.57%. The value of children's environmental awareness based on the results of the questionnaire is still low, namely 49.86%. And from the survey results, the government must raise environmental awareness among the people of Plaju sub-district, which must be done by the government, the managers (RT/RW), one of which is the need for support and motivation from related parties such as the government in the form of counseling and providing capital to encourage its citizens to process waste into something useful. useful so that it can convince residents by creating jobs and minimizing waste.
Bencana Badai Siklon Tropis Di Indonesia
Tropical cyclones are powerful storms. Usually the average radius is around 150-200km. This tropical cyclone is formed above the sea where the sea water temperature is warm, more than 26.5 degrees Celsius, and strong winds whose rotation has a speed of 63km/hour. BMKG said that in Indonesia there were at least 12 tropical cyclones that occurred in the archipelago from 2008-2021. This research method uses descriptive methods via the internet, then analyzed using qualitative methods. The impact of tropical cyclones is extreme weather changes in Indonesia whose impacts we can see and feel are significant. BMKG also states that tropical cyclones are dangerous storms because they have enormous strength. The life span of tropical cyclones usually ranges from 3-18 days Because tropical cyclones get energy from warm oceans, tropical cyclones weaken when they move into areas of water where the temperature is cold. Another name for tropical cyclones is "earth storm" which we usually know as "typhoon". Cyclone Dahlia is one of the many cyclones that grow in tropical areas. This natural phenomenon occurs at the end of the year in locations near Indonesian territory.
Aplikasi Fotokatalis TiO2 Dan Alternatifnya Untuk Degradasi Pewarna Sintesis Dalam Limbah Cair
Liquid waste containing synthetic dyes is a significant environmental problem, particularly in the textile industry, such as batik waste. Recent studies have shown the potential of TiO2 photocatalysis in reducing color and Chemical Oxygen Demand (COD) in such waste. In addition to TiO2, ZnO nanoparticles and ZrO2-TiO2 composites have also been tested as alternative photocatalysts for the degradation of synthetic dyes. The use of immobilized TiO2 nanoparticles on various substrates such as plastic sheets, hydrogels, or hybrid films has increased the efficiency of photocatalytic processes and allowed for the separation of photocatalysts from the waste after treatment. Furthermore, the combination of TiO2 with additives such as Mg, Ag, and Fe has enhanced the photocatalytic performance in removing synthetic dyes from wastewater. The use of TiO2-based photocatalytic membranes also enables simultaneous filtration and degradation of pollutants in wastewater treatment. In addition to degrading synthetic dyes, TiO2 photocatalysis has been successfully used to remove natural dyes like Congo red from industrial wastewater. Recent studies have also explored new synthesis methods to obtain TiO2 photocatalysts with enhanced properties, such as TiO2 nanocoating on nanocomposites or TiO2 nanocoating on porous materials. Overall, these studies demonstrate that TiO2 photocatalysis has great potential in liquid waste treatment, particularly in the degradation of synthetic dyes found in textile industry waste like batik waste.

This research method uses experimental methods and The design of this study was Completely Randomized Design with 4 treatments and 6 repetitions. The data analysis technique used ANOVA analysis of variance to examine the differences between more than two groups. The concentrations used in this study were 25%, 50%, and 100%, and the negative control used DMSO. Based on the results of the research with a test level of 1% that the red ginger extract (Zingiber officinale var. rubrum) on the growth of the fungus Candida albicans gave a very significant effect because Fcount > Ftable (78.325>3.10) against the fungus Candida albicans so Ha was accepted, H0 was rejected. The highest average inhibition zone in this study was at a concentration of 100% with a value of 13.14, the average 50% inhibition zone resulted in a value of 11.19 mm and the lowest average inhibition zone was at a concentration of 25% with a value of 9.77 mm. This shows that red ginger extract (Zingiber officinale var. rubrum) has an effect on the growth of the fungus Candida albicans. As for the results of the Duncan's Real Distance Difference Test (BJND) at the treatment concentrations P0, P1, and P3 there were real differences at distances 1, 2 and 3 which were significantly different
