Abstract

ABSTRACTThis study aims to study the daily behavior of adult maleo birds in captivity in the Bogani NaniWartabone National Park area. This research was conducted in December 2019. There were 6maleo birds observed consisting of 3 males and 3 females who were placed in cages covering anarea of 20x25 m2. Observations of maleo bird daily behavior were carried out for two weeks,starting at 05.30-10.00 in the morning at 12.00-14.00 and in the afternoon at 15.00-18.00observations were made directly. Each maleo bird behavior included in the observation variablewas observed at time and duration (hours). The results of this study indicate that maleo birds arediurnal birds where the behavior of maleo birds in captivity is social behavior 68.54% morningand afternoon eating behavior 20.16% and resting behavior 11.30% and behavior of femalemaleo birds in captivity. In captivity, social behavior is often done 70.20%, while eatingbehavior in the morning and afternoon is 18.30% and resting behavior is done by maleo birds atnoon and 11.50% in the afternoon.Keywords: Maleo, Daily Behavior, Bogani Nani Wartabone National Park.

Abstract

AbstractMedan Wildlife Park is a conservation area for the Sumatran tiger (Panthera tigrissumatrae) which is kept in an artificial environment and shown to the public. Differentenvironments will affect the daily behavior of animals, and an indicator of successfulconservation is seen from the increase in the number of tigers that survive and are ableto breed (Yelanda, 2017). This research aims to study the daily behavior of thesumatran tiger (Panthera tigris sumatrae) at the Medan Wildlife Park by calculating2the duration and frequency of occurrence of each behavior sumatran tigers (Pantheratigris sumatrae) in the Medan Wildlife Park. The results of this study indicate that thereare five behaviors of the sumatran tiger (Panthera tigris sumatrae) in the MedanWildlife Park, with the percentage of duration and frequency of behavior from thehighest to the lowest is resting behavior (49.23%) with a relative frequency of 41.48%,moving places ( 41.02%) with a relative frequency of 37.47%, others (4.94%) with arelative frequency (12.71%), social (2.60%) with a relative frequency of 4.39%, andeating ( 2.20%) with a relative frequency of 3.95%. The daily behavior of the Sumatrantiger has differences in terms of length of time, manner, and behavior in the MedanWildlife Park with behavior in the wild. Based on the different tests conducted, it isknown that male and female sumatran tigers (Panthera tigris sumatrae) have differentforms of behavior but do not have a significant difference in behavior duration.Keywords: daily behavior, sumatran tiger (Panthera tigris sumatrae), medan wildlifepark

Abstract

Abstract The research to measure the tolerance level of the Knobbed Hombil to the magnitude of habitat disturbance and the determinants of tree habitat used in the Limited Production Forest of Andagile River - Gambuta River - Ilanga River in North Bolaang Mongondow Regency. Based on the existing habitat disturbance, the Knobbed Hombil in the Andagile River Limited Production Forest - Gambuta River - Ilanga River, North Bolaang Mongondow has a tolerance level in habitats that have 5 to 3 remaining Forest Stratification and found in the Forest Stratification A (> 30 m), the Forest Stratification B (20 - 30 m), and Forest Stratification C (4 - 20 m). The place altitude above the sea level, the physiography, the slope, are suitable habitat conditions for the Knobbed Hombil and also along the trees that are used together with other animals; While it comes with a tolerated noise level by Knobbed Hombil. Key words: Knobbed Hombil Tolerance (Rhyticeros cassidix), Habitat disturbance, Limited Production Forest, North Bolaang Mongondow

Abstract

Abstract The aims to study the daily behavior of Macaca nigra in habituation cage on Mount Masarang, Tomohon city. Data collection was carried out for 2 (two) weeks, from November to December 2022. Daily behavior recording used instantaneous sampling, namely recording behavior at intervals of one minute, the methods used were observation and focal animal sampling. The result showed that the highest proportion of daily behavior of Macaca nigra in the Habituation Cage of Mount Masarang, Tomohon City is social behavior 36.6% followed by moving behavior 27.6% and feeding 24.5% the rest is used for resting 11.3%. The frequency of activity of Macaca nigra male is higher than Macaca nigra female, namely 169 times a day while Macaca nigra female 149 times a day.

Abstract

Penelitian ini bertujuan untuk mempelajari sebaran dan menganalisis fenologi pohon di Kawasan Kampus Universitas Sam Ratulangi. Penelitian ini menggunakan metode sensus dan pohon yang akan diamati minimal diameter batang 20 cm. Hasil penelitian menunjukkan bahwa terdapat 1972 pohon yang terdiri dari 74 jenis pohon yang ditemukan. Sebaran pohon di Kampus Universitas Sam Ratulangi didominasi oleh pohon mahoni daun besar (Swietenia macrophylla) yang tersebar di seluruh lokasi penelitian. Berdasarkan analisis fenologi jangka pendek (short time phenology) yang dilakukan pada bulan Juni-Juli di Kampus Universitas Sam Ratulangi, menunjukkan beberapa pohon angsana (Pterocarpus indicus) tidak berdaun karena pohon tersebut beradaptasi untuk mengurangi tingkat penguapan air yang tinggi. Berdasarkan kriteria pohon dalam kondisi berbunga, jumlah pohon jenis spoit (Spathodea campanulata) yang memiliki kondisi berbunga terbanyak dengan jumlah kondisi bunga kuncup 15 pohon, bunga mekar 25 pohon, bunga layu 23 pohon dan bunga gugur 26 pohon. Berdasarkan pohon dalam kondisi berbuah, jumlah pohon yang berbuah muda terbanyak yaitu mangga kweni (Mangifera odorata) 26 pohon dan jumlah pohon yang berbuah coklat (52 pohon) dan buah gugur (63 pohon) terbanyak yaitu pohon sengon (Paraserianthes falcataria).
