Abstract

Dedap Island is a group of small islands in the waters off the coast of Abang Island which is famous as a spot for anglers because of its clean location and abundance of marine life. This research is focused on identifying the diversity of Echinoderms in the waters surrounding Dedap Island, located in Abang Island sub-district, Batam City, Indonesia. Additionally, it examines the factors that influence the distribution and abundance of these species. The observation was conducted using line transect methods across various locations, leading to the identification of five species of Echinoderms: three from the class Holothuridae (sea cucumbers), one from the class Astroidea (starfish), and one from the class Echinoidea (sea urchins). The species Diadema setosum (sea urchin) emerged as the most dominant, with a total of 361 individuals recorded. The diversity index (H’) for Echinoderms in Dedap Island was classified as low (0.40), and the evenness index (E) also indicated low values (0.25), suggesting an uneven distribution of individuals and dominance by certain species. Contributing factors to this low diversity include ecological pressures, unstable productivity, and substrate conditions primarily composed of sand

Abstract

Penelitian ini mengeksplorasi penerapan konsep agiliti (ketangkasan) organisasi di Sekolah Menengah Atas di Kota Batam, yang terpusat pada ancaman dan kesempatan yang dijumpai selama proses transformasi. Metodologi yang dipakai yakni deskriptif kuantitatif, kuesioner disebar guna mengumpulkan data kepada para guru. Temuan penelitian mengungkapkan bahwa mayoritas pendidik mempunyai kemampuan yang kuat dalam beradaptasi dan berinovasi, dengan skor rata-rata tertinggi terkait perubahan (P1: 4,32) dan terendah mengenai kolaborasi antara guru dan siswa (P15: 3,42). Penelitian ini menekankan pentingnya modifikasi dalam program pelatihan untuk mendorong kolaborasi serta komunikasi yang lebih efektif antara pendidik dan peserta didik. Selain itu, penelitian ini juga menggarisbawahi pentingnya ketangkasan organisasi dalam meningkatkan kinerja sekolah dan responsivitas terhadap perubahan. Rekomendasi diberikan untuk meningkatkan ketangkasan di sekolah dengan mempromosikan kolaborasi, komunikasi yang efektif, dan keterlibatan siswa yang lebih besar dalam proses pembelajaran.

Abstract

Background: Mangrove ecosystems are globally significant for biodiversity, carbon storage, and coastal protection, yet they are increasingly threatened by anthropogenic activities. Indonesia, which hosts the world’s largest mangrove area, also experiences one of the highest degradation rates, making site-specific assessments essential. This study investigates the stand structure and degradation level of mangrove vegetation in Pongkar Village, Karimun Regency, Riau Islands Province, where ecological importance intersects with human pressures. Methodolgy: Field surveys were conducted using five 100 m transects with 10 × 10 m plots for vegetation analysis and a 1 ha plot to assess degradation levels following the Indonesian Ministry of Environment Decree No. 201/2004. Vegetation parameters, including density, frequency, dominance, and Importance Value Index (IVI), were measured. Results: Nine mangrove species were identified, comprising seven true mangroves and two associated species. Rhizophora apiculata dominated the community (density 0.078 ind/m²; IVI 121.15%). Diversity indices revealed medium diversity (H′ = 1.45–1.89), low to medium richness (Dmg = 1.28–1.78), high evenness (E = 0.81–0.86), and low dominance (D = 0.18–0.26). Stand density reached 1,181 trees/ha, classified as medium.These results suggest that ecological functions remain active, but moderate diversity and richness indicate vulnerability to disturbance and degradation risks. Contribution: The study provides empirical evidence to inform conservation planning, emphasizing the need for regular monitoring, rehabilitation of underrepresented species, and community-based management to sustain the Pongkar mangrove ecosystem

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 community structure of Tridacnidae in the shallow coral waters of Dedap Island, Batam, has been analysed through a quantitative approach to reveal ecological dynamics and exploitation pressures from the surrounding communities. This study employed transect methods and ecological index analysis, including Shannon-Wiener diversity (H?), evenness (E), and Simpson's dominance (D) across five observation stations. The results indicate a high dominance of Tridacna crocea in locations with low exploitation pressure, whereas T. maxima and T. squamosa, which are still hunted by the local population, exhibit limited abundance. Pearson correlation revealed that dissolved oxygen (DO) has a strong positive relationship with H? and E, and a negative relationship with D, while temperature showed an inverse relationship. The integration of ecological analysis with socio-ecological factors revealed that anthropogenic exploitation pressures also shape community structure spatially. This study offers a holistic approach to the conservation management of Tridacnidae based on community participation and habitat zoning, while simultaneously addressing gaps in ecological and social research in the coral reef areas of western Indonesia.

Abstract

Kerusakan ekosistem mangrove di pesisir Pulau Batam menjadi masalah krusial yang berdampak pada lingkungan dan ekonomi masyarakat. Program Pemberdayaan Kemitraan Masyarakat ini bertujuan meningkatkan kapasitas kelompok masyarakat Akar Bhumi Indonesia dalam merehabilitasi mangrove dan pengelolaan sampah plastik secara berkelanjutan. Metode pelaksanaan meliputi tiga kegiatan utama: pelatihan penanaman dan perawatan mangrove, rehabilitasi mangrove dan workshop pembuatan paving block dari limbah plastik. Hasil kegiatan pemberdayaan kemitraan masyaraat menunjukkan 1).peningkatan signifikan pada pengetahuan mitra, dengan nilai rata-rata pre-test meningkat dari 47,25 menjadi 79,75 pada aspek pengelolaan mangrove dan pengolahan sampah plastik. Selain itu, kegiatan ini 2).berhasil mengurangi ±150 kg sampah plastik dan menghasilkan paving block yang dimanfaatkan untuk infrastruktur lokal dan 3).penanaman 750 pohon di area ±1.000 m², Program ini menunjukkan bahwa pendekatan edukatif dan partisipatif mampu memperkuat konservasi lingkungan dan memberdayakan masyarakat pesisir secara simultan.
