Abstract

The waste problem along the coast of Persiapan Empol Village poses a serious threat to the environment and community welfare, primarily due to household, market, and daily waste that is often carelessly disposed of into the river. In response, the Thematic Community Service Team from Universitas Mataram implemented a program to raise community awareness about waste management and empower them to transform waste into environmentally and economically beneficial products. This activity aims to increase public awareness of environmental issues, particularly waste management. The methods used include socialization, practical training, and community empowerment, focusing on enhancing community participation. As a result, residents are now more aware of the importance of waste management, and the village administration has provided land for a temporary disposal site (TPS) and urged residents not to dispose of waste in the river. This program demonstrates positive progress in efforts to preserve the coastal environment.

Abstract

Osmoregulation is a process used by fish to maintain the balance of water and ion levels in the body, so that salinity becomes a limiting factor for the life of Tilapia fish. This study aims to determine the effect of salinity on osmoregulation, physiological survival and respiration rate of Tilapia fish (Oreochromis niloticus). This research design used an experimental method with a Completely Randomized Design (CRD) approach. This research design involved four different treatment levels and was carried out with five repetitions for each treatment. Each treatment was designed to test the effect of a particular variable on the observed parameters, with repetitions aimed at ensuring consistency of results. P1: Control (No Filter). P2: Salinity 5 ppt. P3: Salinity 10 ppt. P4: Salinity 15 ppt. The activity of tilapia in each salinity medium was observed to determine changes in behavior after the fish were inserted into the salinity medium. Physiological responses were observed, and the respiration of tilapia through operculum movements in each salinity medium was calculated after 5 minutes of treatment for 1 minute. Survival was calculated after 5 minutes of treatment until the tilapia died. Data were analyzed using one-way ANOVA, with a significance level of 5%. If there was a significant difference, it was continued with the LSD test (Least Significant Difference). Based on the ANOVA test, the Sig. value obtained was .000 (<0.05), indicating that there is an effect of salinity on the physiological osmoregulation of tilapia survival (Oreochromis niloticus). Based on the results of the Multiple 12 Comparisons LSD test, it can be seen that all differences between treatment groups are significant with a 95% confidence level (p < 0.05). Based on data analysis and discussion, the study concluded that salinity has a significant effect on the respiratory rate of tilapia (Oreochromis niloticus), where increasing salt levels cause an increase in the frequency of operculum movements in response to osmotic stress. The main factors affecting the survival of tilapia to salinity differences are the ability to osmoregulate, which is increasingly inhibited as salt levels increase, as well as the duration of exposure to more hypertonic environmental conditions.

Abstract

Scientific Reasoning and Scientific Attitude are important aspects of scientific literacy for students to master because they are directly related to the development of science and technology. This study aims to analyze the effect of the Problem-Based Learning model on students' Scientific Reasoning and Scientific Attitude abilities. This type of research is classified as a quasi-experiment with a non-equivalent control group design. The study population consisted of 13 classes of the 10th grade of MAN 2 Mataram, from which two classes were selected as samples determined by purposive sampling techniques. Data were obtained by administering the Scientific Reasoning test and the Scientific Attitude questionnaire. Data analysis techniques include a comparison of average scores and the Mann-Whitney statistical test. The results showed that the experimental class obtained an average score of 75 points (formal), and the control class obtained a score of 72 points (transitional) on the Scientific Reasoning aspect. On the Scientific Attitude aspect, the experimental class obtained a score of 69 (High) and the control class obtained a score of 63 (Moderate). In addition, the Asympt. sig (2-tailed) value on the Scientific Reasoning aspect is greater than 0.05, which is 0.466, while on the Scientific Attitude aspect it is 0.003 or less than 0.05. Based on these findings, it can be concluded that although the Problem-Based Learning model has a significant effect on Students' Scientific Attitude Ability, its impact on Scientific Reasoning Ability is not statistically significant in the context of this study. This can be influenced by external factors that cannot be fully controlled in the research implementation process.

Abstract

This study aims to: 1) compare the osmoregulatory physiological adaptation and survival of Goldfish (Cyprinus carpio) and Nile tilapia (Oreochromis niloticus) after exposure to seawater. 2) Increase the understanding of animal physiology course material, especially on the topic of osmoregulatory physiology of aquatic animals. Osmoregulation is an essential biological process that allows organisms, including fish, to maintain the balance of water and ions in their bodies. This process is closely related to homeostasis, which is the ability of the body to maintain internal stability despite changes in the external environment. This study uses an experimental design method. The research design involved two different treatment groups, one for goldfish (Cyprinus carpio) and one for Nile tilapia (Oreochromis niloticus), with each treatment replicated ten times. Each fish sample was exposed to seawater by placing it in a plastic bucket containing one liter of seawater. The release of the fish into the treatment medium was done simultaneously. Survival time was observed and recorded from the time the fish was exposed until it died. The breathing rate was observed by counting the opening and closing of the operculum for the first 5 minutes after the treatment for 1 minute, with the counting repeated every 5 minutes for 1 minute until the fish died, and then averaged. The data were analyzed using a t-test at a significance level of 5%. The t-test result showed t_observed = 24.232 > t_table = 2.101 at the 5% significance level with 18 degrees of freedom (df). The significance value (2-tailed Sig.) was 0.000, indicating that the difference between the two groups was highly significant (p < 0.05). This study concluded that Nile tilapia (Oreochromis niloticus) has a longer survival time compared to goldfish (Cyprinus carpio) when placed in seawater. The average survival time of Nile tilapia was 78.3 minutes, significantly longer than goldfish, which only survived for 16.8 minutes.
