Abstract

Research on the population structure of Assiminea brevicula associated with mangrove vegetation in Poton Bako Bay, South Coast of East Lombok was conducted in June 2023. This study aims to determine population structure, population density, distribution patterns and the length-weight relationship of Assimineea brevicula gastropods associated with Poton Bako mangrove vegetation, South Coast of East Lombok. Data collection was carried out using the quadratic method using purposive sampling by taking into account the mangrove species found in the observation plots. As a result, the frequency of the number of Assiminea brevicula gastropods in relation to the shell length of the samples was in the size range of 6 mm - 7 mm. The maximum shell length obtained was 10 mm. From the data obtained, the highest density figure during the research was located at station 3, namely 8.24 ind/m2. The population distribution pattern of Assiminea brevicula in Poton Bako is clustered, uniform, and random with a dominant cluster pattern. The length-weight relationship on June 11 2023 obtained the equation W = 0.18L1.04 and on June 18 2023 obtained W = 0.68L0.31, and on June 25 2023 with the equation W = 0.067L1.48 because slope < 3, with a thin shape, the nature of growth is negative allometric, which means that the increase in length of the snail is faster than the increase in weight.

Abstract

Gili Trawangan is one of the popular marine tourism destinations and conservation areas in the West Nusa Tenggara Province. Increased human activity in the Gili Trawangan is associated with increased pressure on aquatic ecosystems. Human activity pressure comes from tourism activities and negative impacts due to various community activities around the waters can reduce water quality. Changes to water quality can be seen from the abundance and composition of phytoplankton. This is because phytoplankton plays an important role in a water body, namely as a primary producer in the food chain and has the ability to respond to the changes of the environment factors. This rearch was conducted to determine the abundance and composition of phytoplankton community structure in Gili Trawangan, North Lombok. Seawater samples were taken using a 20 µm plankton net by filtering 100 L of water. The filtered water samples were then preserved using formalin in 4% concentration. Data were analyzed by calculating the abundance of individuals, diversity (H'), uniformity (E), and dominance (D). The results showed that the average abundance of phytoplankton species was 1026.296 Ind/L and 22 genera of phytoplankton were identified. Species diiversity index (H'=2.58) is classified as medium. Species uniformity index (E=0.88) and species dominance index (C=0.10). Based on the results of this research it can be concluded that the waters of Gili Trawangan North Lombok are classified as oligotrophic waters.

Abstract

The eastern little tuna is one of a pelagic fish that has an economic important value and mostly landed at Fish Base Landing (PPI) Tanjung Luar. The needs of eastern little tuna are very affordable and sold economically in the markets, which causes a highly catching intensity by the fishermen regardless the catching season, so that many eastern little tuna which caught when they were in gonads matured and spawn session. The purpose of this study was to describe reproduction aspects comprises of gonads maturity stages, gonadosomatic index and fecundity. This research was taken on May till June 2018 from Fish Base Landing in Tanjung Luar. The total samples observed were 120 female fishes which collected from the fish base landing. The sample determination technique in this study was quota sampling. Gonad maturity stages were observed by morphological observation then the gonadosomatic index were measured. Fecundity ware treated on 36 samples at V and VI stages (gonads matured) to be measured by using gravimetric method. The result of this study revealed that gonads maturity of the female eastern little tuna was dominated by the fourth stage (51,67%), and then followed by the fifth stage (36,67%), the third stage (23,33%), the sixth stage (8,33%) the second stage (8,33%) and the first stage (6,62%). From those gonad maturity percentages showed that the eastern little tuna was not in the gonads matured session. The value of gonadosomatic index for the female eastern little tuna were about 0,0116% up to 0,0258%. Meanwhile the fecundity range between 192.246 ova until 601.497 ova on fish with the length between 415 mm until 640 mm.

Abstract

The use of traditional medicine from herbs and natural ingredients has existed for a long time and goes alongside people's lives. So, this study aims to analyze the trend of scientific publications of traditional medicine research from 2015 to 2024. Bibliometric analysis was used, with the assistance of Dimensions.ai, Publish or Perish, and VOSviewer. The keywords used, both in Dimensions.ai and Publish or Perish, are “Traditional AND Medicine AND plant AND ethnobotany” with a time span of 2015-2024. The results showed that “pharmacology,” “herbalist,” and “medicinal plants” were some of the most frequently occurring keywords in this topic. In addition, in scientific publications, research trends also continue to evolve. More specifically, when the COVID-19 pandemic hit, there was a very significant increase in this topic.

Abstract

This study aims to identify and analyze the development of mangrove ecotourism teaching materials on ecosystem material to improve students' scientific literacy skills. Using the systematic literature review method, this study collected and analyzed scientific articles published between 2015 and 2024 through the Google Scholar and Sinta databases. The focus of the study includes keywords such as "Learning Materials Development", "Mangrove", "Ecosystem", and "Science Literacy". The results of the review show that environmental-based teaching materials, especially those that link the concept of mangrove ecotourism, can significantly improve students' scientific literacy. Learning approaches such as project-based learning and the use of interactive media have proven effective in attracting students' interest. This study confirms that the development of teaching materials that are contextual and relevant to students' environment can encourage a better understanding of ecosystems and the environmental issues they face. It is hoped that through direct experience and interaction with the mangrove ecosystem, students will not only gain theoretical knowledge, but will also be able to apply it in their daily lives, thereby contributing to environmental conservation. Thus, the development of mangrove ecotourism teaching materials is expected to be an effective tool in science education and increase students' environmental awareness
