Abstract

Lemuru fish (Sardinella lemuru) is the main small pelagic commodity in the Bali Strait that has high economic value but is vulnerable to pressure on the surface. This study aims to analyze the morphometric and meristic characteristics of lemuru fish landed on Pancer beach, Banyuwangi. The research method used a descriptive survey with stratified random sampling techniques of 50 individuals in the period from October to December 2022.  The results of measurements on 23 morphometric variables showed that the total length was 9 ≤ 19 cm (92%), the standard length was 7 ≤ 17 cm (86%), the body width was 1 ≤ 11 cm (90%), the height of the body was 2 ≤ 10 cm (88%), the height of the tail rod was 1 ≤ 9 cm (84%), the length of the tail rod was 1 ≤ 9 cm (96%), the length of the ventral fin was 1 ≤ 9 cm (90%),  Pectoral fin length 1 ≤ 13 cm (98%), Eye diameter 1 ≤ 9 cm (90%) and weight 10 ≤ 24 g (98%). Meanwhile, the calculation of 14 meristic variables of lemuru fish showed that: Number of Hard Dorsal Radius 2 ≤ 12 (88%), Number of Weak Dorsal Radius 3 ≤ 13 (96%), Number of Hard Anal Fin Fingers 2 ≤ 6 (86%), Number of Weak Anal Fin Fingers 2 ≤ 8 (88%), Number of Scales on Lateral Stripes 54 ≤ 67 (78%), Number of Scales Around the Body 33 ≤ 41 (60%), Number of Scales on Side Lines 5 ≤ 17 (94%),  The number of scales below the side line is 10 ≤ 20 (94%).

Abstract

The development of 21st-century skills requires science education to foster students’ scientific creativity and science process skills through innovative learning models. One instructional approach that has gained increasing attention is Project-Based Learning (PjBL). This study provides a systematic review of the trend of using Project-Based Learning (PjBL) Model in enhancing students' scientific creativity and science process skills during the period 2010-2020, using bibliometric analysis through the Publish or Perish 8 and VOSviewer tools. The results show a significant increase in publications focusing on PjBL, especially in the themes of STEM integration, critical thinking, problem solving, and collaborative learning. PjBL has been shown to not only enhance students' scientific creativity and science process skills, but also increase the interactivity and relevance of learning through the application of technology. Thematic cluster analysis shows a close relationship between educational innovation and cross-disciplinary collaboration in preparing students to face global challenges. From a practical perspective, the application of digital tools in PjBL is highly recommended, especially in distance learning and hybrid classes. This study suggests further exploration of more innovative evaluation methods to measure the impact of PjBL, and emphasizes the importance of implementing this approach to address the challenges of 21st-century education

Abstract

Microplastic pollution has become a significant environmental problem in marine ecosystems, particularly in coastal areas impacted by increased anthropogenic activity. The coastal waters of Kuta, Lombok, are potentially exposed to plastic waste from tourism and fisheries, which can degrade into microplastics and enter the marine food chain. This study aims to identify the types, abundance, and characteristics of microplastics in the digestive tracts of rabbitfish (Siganus canaliculatus) and goatfish (Parupeneus multifasciatus). The study used a modified NOAA method for 60 fish samples, including hydrogen peroxide (H₂O₂) digestion and NaCl density separation, followed by microscopic observation. The results showed that microplastics were present in both fish species, consisting of fiber and fragment types, with fibers being the dominant type. Microplastic abundance was relatively low, at 0.6 particles/individual in rabbitfish and 0.5 particles/individual in goatfish. The dominant colors observed were black, blue, and red. These findings indicate that microplastic contamination has occurred in the study area, albeit at a relatively low level. Therefore, better plastic waste management and increased public awareness are recommended to reduce further contamination in coastal ecosystems.

Abstract

The rise in plastic usage in Indonesia has resulted in a buildup of plastic waste both on land and in water bodies. Because it does not break down easily due to the lack of microorganisms that can degrade it, plastic remains in the environment and pollutes various living beings. Thus, it is important to conduct studies on microplastic contamination to evaluate the safety of fish, which is a widely eaten source of food. This study aimed to determine the abundance and characteristics of microplastics in Ikan Tongkol (Euthynnus affinis) from the coastal waters of Ampenan Beach. Sampling was conducted using a random sampling method. Tuna samples were collected from fishermen along the Ampenan coast three times, totaling 30 fish. The analysis was conducted through sample preparation, oxidation of organic matter, filtration, and microscopic observation. The results showed that microplastics had accumulated in the digestive tract of the Euthynnus affinis, with an abundance of 2.3 MP/Ind. The most dominant type of microplastic found was fiber, accounting for 65% of the total sample, with black being the predominant color. Four types of microplastics were identified in the digestive tract: 65% fiber, 20% fragments, 10% film, and 5% granules.

Abstract

This study aims to describe aspects of the reproductive biology of a blue swimming crab (Portunus pelagicus) that landed at the southern end of the coast of East Lombok during the period November 2023 to April 2024. The study used a descriptive design with a quantitative approach to measure and analyze data through direct observation. Data included carapace width, body weight, gonad maturity stages, and gonad somatic index (GSI) of P.pelagicus. The results showed that the male P.pelagicus population was more dominant than females every month. P.pelagicus body weight varied, with significant increases in certain months caused by spawning. Analysis of the relationship between carapace width and body weight showed positive allometric growth, with b values of 3.17 for males and 3.10 for females, indicating that body weight gain was faster than carapace width. The maturity stages of the P.pelagicus gonads were mostly at stages I and II, with a few reaching stages III and IV. The average gonad maturity stages increased from 2.42% in November to a peak of 5,83 % in February, then decreased in the following months. The primary spawning time occurs from December to February, characterized by changes in gonad color and a decrease in the body weight of the P. pelagicus after spawning. Hopefully, this study’s results can positively contribute to the sustainable management of crabs (P. pelagicus).
