Abstract

Macaca fascicularis, or long-tailed monkey, is a primate found in Southeast Asia, including Indonesia. Despite its abundant population, the long-tailed macaque is classified as an over-exploited wildlife. Therefore, conservation efforts are needed to prevent the extinction of the long-tailed monkey population. One of the natural habitats of the long-tailed monkey is located in Telaga Buret, Tulungagung Regency. In this area, the total number of long-tailed monkeys is unknown and has never been studied. Therefore, this study aims to determine the population and behavior of long-tailed monkeys in Telaga Buret using the scan sampling method in certain time intervals. The results showed that the total population of long-tailed monkeys found in the study site was 98 individuals. The observed behavioral parameters include moving activities, vocalizing, foraging, playing, searching, sexual, interaction with humans, aggression, resting and parenting. From the results of the study, the behavior that has the highest index value is moving (38%) while the least behavior is interacting with humans (1%). The high values generated from the percentages indicate how often M. fascicularis performed these behaviors at each time interval.

Abstract

Macroalgae is a type of tuberous plant that does not have a clear distinction between roots, stems, and leaves. Macroalgae also have a very important role ecologically in marine ecosystems and have been widely utilized in the cosmetics industry, food sources and their potential as medicines due to their bioactive compounds. The presence of macroalgae in the waters is found in the intertidal zone and subtidal zone and occupies a variety of substrates in the waters. One location that has good potential regarding the presence of macroalgae is Kondang Merak Beach because of its natural ecosystem with the presence of mangrove vegetation, seagrasses, coral reefs, and protected forests. So this study aims to determine the types of macroalgae found at Kondang Merak Beach, Malang Regency. The research was conducted on 3 November 2024 in the Kondang Merak Beach area of Malang Regency. The research method used was free roaming with a qualitative descriptive approach. The sampling process was carried out at low tide around 05.00 WIB until 10.00 WIB, then the identification process was carried out in the field and laboratory. The results obtained nine species of macroalgae, namely Halimeda macroloba, Ulva lactuca, Padina gymnospora, Acanthophora spisifera, Hypnea valentiae, Gigartina papillate, Kappaphycus striatus, Galaxaura rugosa, and Palmaria palmata. The presence of macroalgae is also influenced by the abiotic conditions of the waters, the results of abiotic measurements show a temperature of 25.0°C, pH 7.67, DO 7 ppm, turbidity 34 NTU, TDS 14.6 mg/L, salinity 43 ‰, wind speed 1 m/s, light intensity 63372 lux, still in optimal conditions in supporting macroalgae life. Turbidity value of 34 NTU which tends to be rather high can be caused by strong ocean currents and hydro-oseanografi phenomena.
