Abstract

One of the primate species found in the Watangan Puger Nature Reserve is the Javan langur (Trachypitecus auraus). The IUCN Redlist classified this primate as vulnerable and it is included in CITES Appendix II. The aim of this study was to determine the distribution pattern of the Javan langur population in the Watangan Puger Nature Reserve. The data was collected from February to April 2021. A combination of concentrated method (Concentration Count) and ad libitum observation method was employed to obtain data. Analysis of the population distribution pattern was carried out using the Nearest Neighbor, while the population distribution was analyzed using the area of the outermost point of encounter. Both analyzes were performed using ArcGIS software version 10.1 and QGIS version 3.18. There are two distinct groups. In the first group, there were 17 individuals with a population density of 6.54 ind/km2, while in the second group were 9 individuals with a population density of 3.46 ind/km2. The distribution pattern of the population is classified as clustered in all groups with p-value and z-score of 0.000306 and-3.610344 for the first group and 0.000169 and-3.760636 for the second group respectively. The population distribution of Javan langurs in the Watangan Puger Nature Reserve covers about 43% of the total area.

Abstract

The Biosite Pangpang Bay Ijen Geopark (BPBIG) has a high potential biodiversity value outside the conservation area, particularly in the mangrove forest. Namun informasi keragaman ini masih belum sepenuhnya lengkap. Sehingga penelitian ini bertujuan untuk menentukan keragaman jenis burung di hutan mangrove BPBIG. The research was conducted on October 2023 using the point count method at six observation points in the mangrove forest. Data analysis was carried out in two approaches, i.e., species composition and species diversity index using Shannon Wiener index (H’). We recorded 39 bird species, consisting of 32 genera and 21 families, in the mangrove forest of BPBIG. There is one bird species that has important conservation status based on the IUCN Red List and National Regulation, namely L. javanicus (a vulnerable and protected species). Furthermore, there are also three migratory birds (T. sanctus, N. phaeopus, and A. hypoleucos) that use the mangrove forest of BPBIG as stopover sites during migration periods. The results of the Shannon Wiener index showed that the bird diversity in the BPBIG mangrove ecosystem is in the medium category (H' = 2.02). Finally, based on these results, it can be concluded that the bird species in the mangrove forest of BPBIG are quite diverse.

Abstract

Meru Betiri National Park (MBNP) is one of the conservation areas as a habitat for diurnal raptors in East Java. However, the updated information on diurnal raptors in MBNP is still limited, with the latest information recorded in 2014. Therefore, this study aims to inventory the species composition of diurnal raptors in Bandealit Resort at MBNP. This research was conducted in April-June 2022 using the point count method with an observation radius of 1 km. We sampled a total of three observation points in three forest cover types i.e dense vegetation (primary forest), semi-dense vegetation (secondary forest-plantation), and low vegetation (coastal forest). Data collection included diurnal raptors species, frequency of encounters for each species, time of encounter, coordinate points, and activity (flyover, soaring, and perched). The results showed the presence of 10 diurnal raptors at the Bandealit Resort MBNP which consisted of two families (Accipitridae and Falconidae). Based on the IUCN Red list of threatened species, there are eight species of least concern (LC), one species of near threatened (NT), and one species of endangered (EN). The frequency of encounters shows that Crested Serpent-eagle (Spilornis cheela) has the highest frequency value (20%), while the Spotted Kestrel (Falco moluccensis) and Changeable Hawk-Eagle (Nisaetus cirrhatus) have the lowest frequency value (4%). Furthermore, as a special record, the Javan Hawk-eagle (N. bartelsi) is found with a fairly high frequency of encounters (11%). Approximately 75.71% of observed diurnal raptors are in soaring activity. Moreover, based on their distribution area, the primary forest has the highest composition of diurnal raptor species encountered.

Abstract

Javan lutung (Trachypithecus auratus) is an endemic primate species which mostly occurs in protected areas, such as the Bandealit Resort of Meru Betiri National Park (MBNP), East Java, Indonesia. However, scientific information related to the habitat characteristics of T. auratus in this resort is limited. Therefore, the aim of this study is to investigate the habitat characteristics of T. auratus based on the vegetation stratification in the Bandealit coastal forest of MBNP. This research was conducted in March, April, May, and September 2022 using the scan sampling methods at two sites, including Site I (Camping Ground Block) and Site II (Wisma Block). The data on tree species was collected using a plot method (40 m x 20 m). Furthermore, we used the Spatially Explicit Individual-based Forest Simulator (SexI-FS) version 2.1.0 to construct the stratification profile. Based on the results, there were 17 individuals of T. auratus found in two sites along the observation. This species is recorded as occupying seven tree species, including Alstonia scholaris, A. spectabilis, Calophyllum inophyllum, Dracontomelon sp., Pongamia pinnata, Syzigium sp. and Terminalia catappa. According to stratification, T. auratus was found in Stratum B (21-30 m) to Stratum C (5-20 m) at all sites. Furthermore, this species was widely distributed in Stratum C for locomotion, foraging, social activities and self-protection. Meanwhile, T. auratus was observed using A. spectabilis in Stratum B as a sleeping tree in the afternoon and evening. These results can be the basis for in-situ conservation strategies for T. auratus species in MBNP, particularly for habitat management based on occupied vegetation.

Abstract

Bandealit is one of the resorts in Meru Betiri National Park (MBNP). This area has many endemic floras and faunas affected by the presence of invasive alien spesies plants. These plants tend to give negative impacts on savana ecosystem among them is, Lantana camara L. The distribution of this invasive alien spesies in the savana can be used to provide information about the characteristic of the environment. This study was conducted to investigate the patterns of spatial distribution of invasive alien L. camara population in the Pringtali Resort Bandealit savana region. The characters of plant species morphology was recorded for species name identification and validation. Percent cover of the individual L. camara species was collected within 50 plots (5x5 m2), while each of coordinate species found in the plots was recorded by using GPS (Global Positioning System). Abiotic factors such as temperature, pH, light intensity, and soil moisture were measured within the plots. The location of the data collection is 5,000 m2. The distribution pattern of invasive alien L. camara population was analyzed using ArcGIS and Dispersion Morisita’s Index (Ip). The result showed that 51.7% of L. camara population grew spasially close together (clumped) or overlapped one another based on the ArcGIS. This means that L. camara individuals distributein clumped pattern. While the other individuals (48.3%) grew apart randomly from each other. This distribution pattern showed by Ip value, 0.51 was also clumped or clustered. It can be concluded that the distribution pattern ofinvasive alien species L. camara is clumped because the reproduction of plant was by seeds dispersal or vegetative buds that lived around parental individuals.Keywords: ArcGIS, Lantana camara L., Invasive Foreign Plants, Morisita index, Distribution Pattern.

Abstract

Kluwek seeds (Pangium edule Reinw.) have a low germination percentage caused by dormancy due to hard seed coat. Kluwek seed germination takes about 1 month. The purpose of this study was to obtain a combination of treatments that were effective in increasing the percentage of kluwek seed germination and reducing the intensity of kluwek seed dormancy. This study used a Completely Randomized Design (CRD) factorial design. The first factor was immersion time (H) consisting of five levels, namely H0: Control (0 hour), H1: 6 hours, H2: 12 hours, H3: 18 hours, and H4: 24 hours and the second factor was giberellin concentration (G) with five levels namely G0: 0 ppm, G1: 25 ppm, G2: 50 ppm, G3: 75 ppm and G4: 100 ppm. Data analysis used Analysis of Variance (Anava) and further tested with Duncans' Multiple Range test (DMRT) at a significant level of 5%. The results obtained showed that the percentage of seed germination without immersion is 6.67%. Soaking using aquades produces an average germination percentage of 28.33%. The most effective treatment was GA3 75 ppm for 24 hours with seed germination of 60%, while the value of dormant intensity is 40%.Keywords: dormancy, germination, gibberellin, kluwek.

Abstract

Javan langur (Trachypithecus auratus É. Geoffroy, 1812) is categorized by IUCN as a vulnerable primate species since 2008 and protected under 2018 LHK regulation. They can be found across Java Island, also in the Watangan Puger Nature Reserve (WPNR), East Java. There is no information about the population and habitat characteristics of Javan langur in WPNR except their existence. This research study aims to estimate the population structure, population density, and habitat characteristics of the Javan Langur in the WPNR, within the area of 2.6 ha. Three concentration points for daily observations were determined for 3 days. A combination of concentration count with scan sampling observation method at intervals of 30 minutes every hour of observation was done to get the data of density, position, population structure, and plant species preferred by Javan langurs. The important value, diversity Shannon-Wiener index, and plant species preferred were also analyzed. There are 26 population composed of two groups of the Javan langur occupying an area of 1,118 ha (43%). The population size estimatation for the first group was 17 individuals with a population density of 15.17 individu/ha, while that for the second group was 9 individuals with a population density of 8.02 individu/ha. The twenty-six Javan langurs are composed of complete age structure such as adult 69%, sub-adult 15%, and infant 16%. The Javan langur population was mostly found in the vegetation structure of Syzygium jambos (jambu hutan) to Pithecellobium dulce (asam manila) (IV = 45.47 to 3.88). Total 24 tree species are found in WNPR, most of the trees are used by the Javan langur as food and cover. The tree community in WPNR has medium diversity with value of 2.28. Furthermore, the Javan langur prefer Artocarpus elasticus (bendo) and Syzygium jambos (jambu hutan) at the upper strata (> 15 meters) than other trees and strata. Most of them are actively walking or jumping (locomotion) during the activity observed at the tree community.
