Abstract :
Long-tailed monkeys are animals that are able to adapt quickly to the environment so that their distribution is quite wide in the Southeast Asian region to Indonesia. In Indonesia, the distribution of MKK starts from Sumatra, Kalimantan, Java, Bali, to Nusa Tenggara and Papua. Long-tailed monkey habitat consists of primary forest and secondary forest from the lowlands to the highlands up to 1000 meters above sea level. The existence of human interference in the life of fish causes changes in the behavior of fish and tends to exploit human food. Aim To determine the form of the daily activities of long-tailed monkeys in Kelimutu National Park. To determine the effect of the presence of visitors on the daily activities of long-tailed monkeys. Research methods. This research was carried out from March to April 2022 in the Kelimutu National Park. Camera (documentation of activities). GPS (create coordinates). Wristwatch (View observing time). Stationery (Recording Identification and observation results) Type of data Primary data, Daily long-tailed monkey activities, Tourist activity. Secondary data, Visitor data, Map of the area. Data analysis Percentage of activity frequency, Spearman test, Mann Whitney different test. the highest daily activity is eating with a percentage of 32%. The highest way to eat is to scavenge with a percentage of 35%. The highest type of food consumed is human food with a percentage of 47%. Correlation of visitor presence influences social activity, begging, scavenging, stealing, because the p-value is less than 0.05. For the different test, there are differences in the daily activity of long-tailed monkeys because the p-value is less than 0.05.
