Abstract

Gastropods are known to have a wide distribution. They can live in a variety of habitats and influenced by various environmental factors. The aim of this study was to investigate the diversity of gastropods and its relationship with the physical and chemical environment of a water. This research was an ecological research with correlational descriptive type. The selection of Marsegu Island was based on the fact that the area is a conservation area, both the forest and sea are frequently visited by tourists. The results of this research showed that there were 22 species of gastropod found in the water of Marsegu Island. The most commonly found was from the genus of Cypraea (5 species). Gastropods found mostly from the family of Strombidae which consisted of 4 genera i.e. Lambis, Canarium, Strombus and Lentigo. The value of gastropod diversity in the three research stations was moderate, 2.93, 2.91 and 2.95 respectively. In addition, there is a correlation between environmental factors and the diversity of gastropods. The simultaneous effect of the independent variables toward the dependent variables can be explained by the magnitude of the determination coefficient (R Square) which was 0528 or 52.8%. Result of this study confirms that the environmental factors greatly affects the diversity of Gastropod in the coastal waters of Marsegu island. The results can provide benefits as control over fishing and coastal pollution due to human activities.

Abstract

Categories of learning outcomes include acceptance, response, assessment, organization, and pattern formation. Thus, the essence of learning is a change in thinking that affects behaviour. The results of interviews with teachers at SMA Kartika XIII-I Ambon show that current students have not shown an environmentally conscious attitude. Therefore, research was conducted to improve the mastery of the concept of class X students on environmental pollution material using creative problem-solving learning models with guided inquiry strategies. This study used a classroom action research method that took place in two cycles for one month. The subjects in this study were 26 students. The research data were processed descriptively on the results of cognitive, affective, and psychomotor assessments. The results showed that in cycle I there were still 65.4% of students who had not achieved mastery of concepts on environmental pollution material. Therefore, the research was continued in cycle two with the action of using the creative problem-solving learning model based on guided inquiry strategy and coupled with audio-visuals media, as well as a stimulus in the form of giving rewards to active students. It was proven that in cycle II there was an increase in students' mastery of concepts in environmental pollution material in students by 100% so that the series of class action research was no longer continued. In conclusion, the use of learning models

Abstract

Rabbit fish (Siganus vermiculatus) is one of the biological resources in the sea that is widely consumed by the people in Maluku. Rabbit fish are caught during low tide with nets or by using natural resources to poison the fish, such as tuba root (Derris elliptica), which contains rotenone to make fish easy to catch. This study aimed to determining the concentration of tuba root extract that was effective against damage to the liver tissue of rabbit fish. Rabbit fish and tuba root were collected from Oma Village, Haruku Island, Central Maluku District, Maluku Province.  In the study, a laboratory experiment was conducted in which the tuba root was treated with doses of 0.1 g, 0.3 g, 0.5 g and 1 g with an exposure time of 18 to 24 hours. Data were analyzed using two-way analysis of variance (ANOVA) followed by Duncan's post-hoc test. As a result, the lowest level of liver damage in rabbit fish was observed at a dose of 0.1 g, with a total damage of 7 ± 0.00 and 8.5 ± 0.71. Conversely, the highest level of liver damage was observed at a dose of 1 g, with a total damage of 14 ± 0.00 and 15 ± 0.00. The results of the post hoc test showed a subset value of 0.1 g dose (7.75), 0.3 g dose (9.25), 0.5 g dose (12.00), and 1 g dose (14.50). This research indicates that administering tuba root to rabbit fish can result in damage to the liver's structure. The severity of this damage is contingent upon the dose administered, whereas exposure duration does not affect the level of damage to fish organs.
