Abstract

The black rubber sea cucumber (Holothuria leucospilota) is prevalent along the coast of Dedap Island in Batam, unlike other sea cucumber species that face significant fishing pressure. This study examines the population and distribution of Holothuria leucospilota near Dedap Island in Abang Island, Batam. Surveys were conducted at three sites, where we carefully counted and mapped the sea cucumbers. A total of 236 individuals were recorded, with the highest density in Transect 1 (0.97/m²) and the lowest in Transect 2 (0.66/m²). Our results indicate notable variability in sea cucumber density across the surveyed areas, with some locations showing high abundance and others fewer individuals. The distribution pattern, assessed using the Morisita Index, suggested a clustering tendency, especially in Transect 1. We also examined substrate types to better understand these distribution trends. Additionally, water quality assessments showed that conditions across the transects were favourable for sea cucumber survival, with suitable levels of salinity, pH, and dissolved oxygen. These findings are vital for the management and conservation of sea cucumbers in the area.

Abstract

The Amorphophallus flower is one of the Endangered species, so there needs to be an effort to preserve breeding with a fast time, namely artificial vegetative. In addition, the a need for a growth hormone to accelerate the growth process so that the number is not extinct, namely growth regulators (ZPT). The purpose of this study was to breed A. titanum vegetatively supported with growth regulators (ZPT) to improve quality and growth rates. The method used is a completely randomized design (CRD), which is divided into 4 treatments namely A (coconut water), B (shallots), C (bamboo shoots), and D (control) with a total of 4 replications so that in this study there were 16 plants (polybags). The results showed that the natural growth regulator treatment of shallot extract gave the best results in the parameter of the number of shoots, while coconut water extract gave the best results in the parameters of shoot length and growth time. Based on the results, it can be concluded that the use of natural growth regulators from coconut water, shallots, and bamboo shoots affects the growth rate of Amorphophallus titanum.

Abstract

This study used a qualitative, exploratory approach to explore the diversity and distribution of crabs in the Mangrove Forest Area of Tongke-Tongke. This study aims to identify the crab species present in the area. Conducted in January 2023, the research focused on four stations representing two distinct zones within the mangrove ecosystem. Stations 1, 3, and 4 were situated in the rehabilitation zone, characterised by varying levels of vegetation density and substrate conditions, while Station 2 represented an ecotourism area with higher human activity. Observations identified 11 crab species across six families, each exhibiting distinct morphometric and ecological adaptations to their respective microhabitats. Environmental parameters, including substrate type, salinity, temperature, and dissolved oxygen, were found to significantly influence species distribution and diversity. The findings emphasize the ecological importance of mangroves as biodiverse habitats supporting specialized niches for various crab species. This study contributes valuable insights into the conservation and sustainable management of mangrove ecosystems, particularly in balancing ecological preservation and human utilization.

Abstract

Science process skills are essential abilities involving thinking, reasoning, and acting effectively to achieve scientific goals. While the Guided Inquiry Learning model has shown effectiveness in improving these skills, its application in the coordination system topic, particularly using human reflex practicum, remains under-researched. At SMAN 1 Tilango, Grade XI students learn the coordination system mainly through theoretical instruction, with limited practical activities. This reduces opportunities for students to develop science process skills such as observing, experimenting, and analyzing data. This study aimed to analyze learning implementation and students’ science process skills through a human reflex practicum using the Guided Inquiry Learning model. Conducted in October 2024 at SMAN 1 Tilango, the research involved 20 Grade XI students and used a quantitative descriptive method. Data were collected via observation sheets focused on learning implementation and science process skills. The findings showed that all learning stages were implemented effectively, and students actively engaged in scientific activities. The highest achievement was in observation skills, with an average score of 87%, classified as very good. The Guided Inquiry model offered meaningful learning experiences and improved students’ scientific understanding through direct involvement.

Abstract

SIRT1 is a key member of the sirtuin family, exerts a unique protective effect on endothelial cells by modulating various proteins, and has a role as an anti-aging biomarker. Hypertension is pathology chronic pathological condition that disrupts ROS and antioxidants. Little evidence showed that sirtuin has a role in chronic oxidative stress. Therefore, the objective of this study was to analyze the relative expression of Sirtuin-1 in hypertension. This is a case-control study with 30 subjects, adults 50-60 years old in each group. JNC 8 was used to determine blood pressure. Quantitative Real Time PCR was used to calculate the level of Sirt-1. The Livak method was used for relative expression. JASP software was used for data analysis. Our study showed Sirtuin-1 mRNA expression was significantly lower in the hypertension group than the normotension group. It was 0.52 fold lower in hypertension. Sirtuin-1 stimulates antioxidants such as superoxide dismutase and catalase through FOXO-dependent signaling. It has a similar role to antioxidants for eliminating ROS. Sirtuin-1 expression is significantly reduced in individuals with hypertension, suggesting its potential role in oxidative stress regulation and its value as a biomarker for vascular aging and hypertension-related endothelial dysfunction.Keyword: Sirtuin-1, hypertension, expression, mRNA
