Abstract

ABSTRACT DIVERSITY OF AQUATIC BIRD SPECIES IN KAKAS DISTRICT, NORTH SULAWESI The objectives of the research are to determine the waterbird diversity, community structure and composition. It is also to compare bird communities in the lake and the adjacent forested area. The study was conducted in January to February 2020 in Kakas, Minahasa Regency, North Sulawesi. The water bird communities were observed by count point method along the lake-line and on a transect in the forested area. There were seven observation points along the lake and three at the forested area. The results show that there are 54 species of birds (22 families) with 17 (6 families) species of waterbirds. The community structure and composition in lakes is different to the forests. Species with high important values on the lake are Collocalia esculenta, Egretta garzetta, Ardeola speciosa, Hirundo tahitica, dan Ardea alba (IV 38.74-12.91). The important species in the forested area are Collocalia esculenta, Milvus migrans, Corvus enca, Cinnyris jugularis, dan Zosterops montanus (IV 43.99-12.53). The Shannon-Wiener index is medium 2.25 and the evenness is high 0.70. The community similarity index is low at 0.36. Keywords : Water Birds, Species Diversity, Kakas District

ABSTRACTThe purpose of this research is to be able to find out and analyze the diversity ofbird species in some land cover at Manembo-nembo Wildlife Reserve. Thisresearch was conducted in January-March 2020, a research location in theManembo-nembo Wildlife Reserve area which includes the administrative area ofSouth Minahasa Regency. The method used is the method of point count with thenumber of 7 points used as observation samples with each primary dry land forest3 points, dry land farming 3 points and dry land agriculture mixed with shrubs 1point. The data analysis used is (Shannon-Wiener Diversity Index), (RelativeAbundance Index), (Average Index) and (Type Similarity Index). The resultsshowed that there are 60 species of birds from 28 families in the Manembo-nemboWildlife Reserve in the South Minahasa adiministration region. This area has adiversity value (3.21) as an indicator of the high diversity of bird species. Forprimary dryland forest cover has a diversity index value (3.01) with a total of 34types, a value (2.97) with a total of 31 types on agricultural cover of dry landmixed with shrubs and the lowest value on dryland agricultural cover (2.77) witha total of 42 types.Keywords : Diversity of bird species, Land cover, Manembo-nembo WildlifeReserve

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

ABSTRAKRangrang ants are one of the non-timber forest product commodities from the fauna group. Weaverants have the benefit of regulating ecological functions as decomposers and help pollinate floweringplants. Economically, weaver ant eggs are used for bird feed. The research was carried out in theBatuputih Nature Park Forest, Bitung City, North Sulawesi Province, for one month in March 2019. Thisstudy aims to determine the type of host plant and the population of the number of weaver ant nests inBatuputih TWA. The method used is a systematic strip sampling by recording all trees that have nests andpurposively to determine the sample. The results of the study showed that there were 14 (fourteen) typesof weaver ant host plants, namely sempur (Dillenia indica L) 57, forest walnut (Canarium littorale BI) 48,titolang (Gastonia serratifolia Miq.) 40, noni (Morinda Citrifolia L.) 33, wood egg (Alstonia angustifoliaWall.ex A.

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

AbstractThe aim of this research was to determine the variation in carbon storage of eachspecies, total carbon accumulation, and the contribution of carbon of each species to thetotal carbon accumulation in the Wolter Monginsidi street. Data collection was carriedout in December 2020, using the non-destructive method and analyzed using specificand general allometric formulas. The data was collected by means of a census of treeswith a diameter of ≥ 10 cm, which were found along Wolter Monginsidi street, startingfrom the Boboca Malalayang Monument to the Bahu Police Station. The results showedthat, Samanea saman had the highest carbon storage value of 50,10 tons/tree, followedby Ceiba pentandra and Garuga floribunda with carbon storage values of 4,09 tons/treeand 2,58 tons/tree. The accumulated total carbon storage of Wolter Monginsidi street is9.787,09 tons, with variations in the three street segments. The highest accumulation(2.222,72 tons/ha) was in the early segment. The average carbon storage each tree is14,18 tons/tree. Samanea saman contributed 71,4 %, Ceiba pentandra 5,8 % andGaruga floribunda 3,7 %, to the total carbon storage accumulation of WolterMonginsidi street.Keywords: Carbon, biomass, non-destructive, shade trees.

Abstract

ABSTRACT Efforts to maintain the availability of nutrients on the soil are very important in efforts to maintain forest productivity. Litter are materials that have died, located above ground level that will later undergo decomposition and mineralization. The study aims to find out and compare the littering prodication of Spathodea campanulata, Palaquium obovatum, and Ficus benjamina trees in Mount Tumpa Forest Park. The study was conducted on the spathodea campanulata, palaquium obovatum, and ficus benjamina trees. The method of collecting the production of litters using litter traps placed under the trees Spathode campanulata, Palaquium obovatum, and Ficus benjamina is then taken once a week for three weeks. The results of this study showed that of the three main tree types on Mount Tumpa, the highest production with an average of 3,094.64 (g/tree) addressed by Ficus benjamina followed by Spathodea campanulata as many 1,119.99 (g/tree) and Palaquium obovatum as much as 600.71 (g/tree).
