Abstract

This study aims to determine the preferences of rats for different types of feed in the residential area of ​​RT 6 and RT 8, Kandang Limun Village, Muara Bangkahulu District, Bengkulu City. The method used was random sampling with 20 clip-type mouse traps and four different types of feed baits distributed randomly around the residential areas of RT 6 and RT 8 in Kandang Limun Village. The rat collection was carried out in five replications and the number was counted, identified and preserved. Rat morphometry data were analyzed quantitatively and described descriptively. The results showed that there were two types of rats with a total of 13 individuals collected, namely Rattus tanezumi (12 individuals) and Suncus murinus (1 individual). The level of preference of rats for salted fish is 6%, sweet potato and corn is 3%, while cassava is the least preferred feed (1%). In conclusion, two species of rats were found in the residential area of ​​RT 6 and RT 8, Kandang Limun Village. The rats prefer salted fish bait than sweet potato, corn and cassava.

Abstract

Salah-satu habitat monyet ekor panjang (Macaca fascicularis fascicularis) di Kota Bengkuli adalah Taman Wisata Alam (TWA) Pantai Panjang. Kualitas habitat primata ini diduga telah mengalami degradasi karena berbagai aktivitas manusia sehingga telah berdampak pada aktivitas hariannya. Penelitian ini bertujuan untuk mengetahui aktivitas harian pada monyet ekor panjang (M. fascicularis fascicularis). Penelitian ini dilakukan pada bulan November 2021 - Januari 2022 di Kawasan TWA Pantai Panjang, Kota Bengkulu. Pengamatan dilakukan menggunakan metode scan sampling untuk mengetahui aktivitas hariannya yaitu meliputi aktivitas makan, berpindah tempat, istirahat, bermain, grooming, kawin dan konflik, jenis tumbuhan pakan, pohon untuk istirahat serta tidur monyet ekor panjang. Hasil pengamatan yang diperoleh dianalisis secara statistik deskriptif kualitatif untuk menggambarkan dan menjelaskan aktivitas harian dari monyet ekor panjang. Aktivitas harian monyet ekor panjang, yang paling banyak dilakukan adalah berpindah (39,51%) istirahat (28,88%), makan (13,56%), bermain (6,52%), komunikasi (4,91%), konflik (1,6%), grooming (5,0%) dan kawin (0%). Jenis tumbuhan disukai yaitu Soneratia alba J.I (Pedada/Bogem) sedangkan pada Derris trifoliata Lour sedikit disukai. Bagian organ tumbuhan yang disukai oleh monyet ekor panjang adalah daun muda, bunga, buah, dan batang muda.

Abstract

The research aims to determine the number of individuals, age structure and sex ratio in the Simpai population or sub-population in the Bukit Daun Protected Forest. The research used the direct sencus method or direct counting of individual hoops (P. m. melalophos) in a sub-population in the field. Observations were carried out at 06.00-18.00 WIB and increased observations were carried out four times on different days. The research results show that there are three sub-populations of Simpai in the Bukit Daun Protected Forest Area. The number of individuals in the first sub-population is 10 individuals, the second sub-population is 13 individuals, and the third sub-population is 15 individuals. Based on the age structure, the number of young individuals, namely teenagers and children, including babies, in the third sub-population is greater (24 individuals) compared to adults (14 individuals). The sex ratio of adult male and female hoops, namely (1:3) in subpopulations I and II, is higher than subpopulation III (1:2), whereas in the juvenile group, the sex ratio in subpopulation III (1:4) is higher than subpopulation I and II (1:2).

Abstract

This study aimed to estimate the aboveground biomass, carbon stock, and carbon dioxide (CO₂) sequestration of coastal she-oak (Casuarina equisetifolia) stands in Muara Cemara, Pantai Panjang, Bengkulu City, and to describe their ecological functions based on field observations. The study was conducted in September 2025 using a non-destructive method based on the allometric equation ln Y = –2.177 + 2.523(ln DBH). Data were collected from 17 systematically established plots, each measuring 20 m × 20 m. The results showed that the stands had an aboveground biomass of 2.37 ± 0.63 t ha⁻¹, a carbon stock of 1.09 ± 0.20 t C ha⁻¹, and CO₂ sequestration of 4.01 ± 1.06 t CO₂ ha⁻¹. The 21–30 cm diameter class contributed the largest proportion of total biomass and carbon stock, indicating the important role of medium-sized trees in carbon accumulation. Ecologically, C. equisetifolia may contribute to reducing coastal erosion, stabilizing sandy substrates, improving microhabitat conditions, and supporting coastal habitat functions. These findings indicate that C. equisetifolia stands have potential as a complementary component of coastal carbon storage, climate change mitigation, and ecosystem-based coastal management in sandy coastal environments.

Abstract

Phytoplankton are primary producers that respond rapidly to environmental changes and therefore have considerable potential as bioindicators of aquatic ecosystem conditions. This study aimed to analyze the abundance and community structure of phytoplankton and evaluate their ecological significance as bioindicators in the Uram River, Lebong Regency, Bengkulu Province. Sampling was conducted at four stations representing different habitat characteristics along the river continuum, including upstream, dam-influenced, settlement-associated, and downstream segments. Phytoplankton samples were collected using a plankton net and identified microscopically. Community analysis included abundance, Shannon-Wiener diversity, evenness, and dominance. A total of 52 phytoplankton species belonging to eight classes were identified, with Bacillariophyta as the dominant group, contributing 46.2% of the total species composition. The highest abundance was recorded at Station I (2,316.6 ind/L), while the highest diversity index was observed at Station III (H' = 3.380). High evenness values (0.855–0.898) and low dominance values (0.072–0.097) indicated a relatively stable community structure. Variations in phytoplankton composition among stations reflected differences in habitat conditions influenced by flow velocity, substrate characteristics, riparian vegetation, and human activities. These findings demonstrate that phytoplankton are effective bioindicators for assessing ecological conditions and provide baseline information for aquatic resource management and biomonitoring programs in the Uram River.
