ANALISIS VEGETASI DAN KEANEKARAGAMAN JENIS MANGROVE DI PESISIR PERAIRAN PULAU ABANG KECAMATAN GALANG KOTA BATAM Gultom, Monica Christi Artani Penelitian ini bertujuan untuk menganalisis tingkat keanekaragaman jenis mangrove di wilayah perairan Pulau Abang, Kecamatan Galang, Kota Batam, yang dilaksanakan pada bulan Agustus hingga September 2024. Metode penelitian yang diterapkan adalah systematic sampling with random start, dengan pengamatan dilakukan pada empat plot penelitian yang mencakup total area seluas 60 hektare. Data yang dikumpulkan meliputi jumlah spesies, diameter batang, serta tinggi pohon mangrove. Analisis difokuskan pada perhitungan Indeks Nilai Penting (INP) dan Indeks Keanekaragaman (H’). Hasil penelitian menunjukkan adanya 12 jenis mangrove yang termasuk dalam 8 famili. Spesies dengan nilai INP tertinggi adalah Rhizophora apiculata dengan persentase sebesar 80,60%, sedangkan nilai Indeks Keanekaragaman (H’) tercatat sebesar 2,093, yang dikategorikan sebagai tingkat keanekaragaman sedang. Aktivitas manusia di wilayah tersebut diduga berkontribusi terhadap penurunan tingkat keanekaragaman, sehingga diperlukan strategi pengelolaan dan upaya konservasi yang lebih efektif untuk menjaga kelestarian ekosistem mangrove di Pulau Abang.

The Language Style Used by YouTuber Bailey Sarian in Chris Watts – 2000 Page Discovery Murder, Mystery & Makeup Azmi, Putri Wulandari Nurul; Shalehoddin; Adam; Sinaga, Juwita B; Manurung, Sulastri This research analyzed the language style used by YouTuber Bailey Sarian in the video “Chris Watts – 2000 Page Discovery Murder, Mystery & Makeup” using Martin Joos's (1967) language style theory, which classified language styles into five types: frozen, formal, consultative, casual, and intimate. The purpose of this research is to determine what language style Bailey used in that video and which language style is dominant. Using descriptive qualitative methods, the document data collection technique, Miles and Huberman’s model analysis technique, and analytical template, the researcher identified and analyzed the video transcript, resulting in a total of 253 data, consisting of 5 formal styles, 113 consultative styles, 133 casual styles, and 2 intimate styles. The results show that Bailey Sarian uses informal and flexible language, making the storytelling more engaging, easy to understand, and emotionally resonant, while still maintaining its informative purpose. No frozen language styles were found in the analyzed data. It can be seen that the dominant language style used was casual. This research concluded that the appropriate language style served an important role in the effectiveness of storytelling content on social media such as YouTube.

Exploration of Community Structure and Density of Sea Cucumbers (Holothuroidea) in the Tropical Waters of Abang Island, Batam Savitri, Yulia; Efendi, Yarsi; Syamsi, Fauziah This research aims to explore the community structure and density of sea cucumbers (Holothuroidea) in the tropical waters of Abang Island, Batam. The methodology employed involves field surveys using a transect-quadrant technique for the collection of data on species, density, and environmental parameters such as temperature, salinity, pH, and dissolved oxygen. The results indicate that the species composition is dominated by Holothuria leucospilota at Station 1 and Holothuria fuscocinerea at Station 2. The highest density for Holothuria leucospilota was recorded at 0.130 individuals/m² at Station 1, while Holothuria fuscocinerea reached a density of 0.150 individuals/m². The highest diversity index value was found at Station 1 (H' = 1.07), whereas the highest dominance was recorded at Station 2 (D = 0.691). Pearson correlation analysis revealed that salinity and temperature have the most significant relationship with sea cucumber abundance, varying by station location. These findings suggest that the community structure of sea cucumbers is heavily influenced by habitat characteristics and environmental quality.

Diversity of bird species in the Duriangkang Protected Forest, Batam City Irsi, Anjeli Julia; Syamsi, Fauziah; Efendi, Yarsi This study aims to identify bird species, analyze their diversity levels, and assess their habitat conditions. This study used a descriptive quantitative method, where observations were conducted using the point count method at three different locations: forest edges, forests, and gardens. From the results of the study, a total of 21 bird species were successfully identified. There were significant differences in diversity between the three locations. The forest (Station 2) recorded the highest level of diversity (H' = 2.21) and the lowest species dominance (D = 0.14) due to its complete and natural vegetation. This condition provides abundant food sources and shelter, thus supporting the existence of many bird species in a balanced manner. In contrast, gardens (Station 3) had the lowest diversity (H' = 1.74) and the highest species dominance (D = 0.22). This is thought to be due to less diverse vegetation and high disturbance from human activities. Meanwhile, the forest edge (Station 1) was in the middle condition, with moderate diversity (H' = 2.00) and moderate dominance (D = 0.20). This situation indicates that the area still benefits from the forest environment, but is also beginning to be pressured by surrounding human activities. Overall, it can be concluded that natural and diverse habitats support a higher diversity of bird species, while disturbed areas tend to have lower diversity and are dominated by certain species.
