Abstract

Some areas in Bukit Barisan Selatan National Park have serious environmental problems related to the invasion of Merremia peltata (Family: Convolvulaceae). This study investigated abiotic factors influencing the invasion. The research compared abiotic conditions in three forest locations with different invasion levels: severe, moderate, and mild. Measured abiotic factors included percentage of tree canopy cover, microclimate variables (temperature and humidity), elevation above sea level, and the physical and chemical properties of the soil surface. In this study, canopy cover was categorized as an abiotic factor because it affects the amount of light reaching the forest floor. A post-hoc Duncan's Multiple Range Test (DMRT) was performed to determine significant differences (p < 0.05) among abiotic variables. Additionally, correlation analysis and multiple linear regression were conducted to evaluate the relationships between abiotic factors and the level of M. peltata invasion. Multiple regression analysis showed that canopy cover significantly (p < 0.05) affected the invasion. Based on the generated model, a 1% increase in canopy cover would decrease the M. peltata invasion by approximately 2.8%. Soil nutrient analysis through multiple linear regression revealed that the C/N ratio, and concentrations of P₂O₅, Ca, Mg, and Na significantly (p < 0.05) influenced invasion level. An increase in C/N ratio and concentrations of P₂O₅ and Ca were correlated with a reduction in invasion, whereas increases in Mg and Na concentrations were associated with higher invasion levels. Overall, the invasion of Merremia peltata in Bukit Barisan Selatan National Park was influenced by an open forest canopy and was associated with high concentrations of Na and Mg in the soil of invaded areas.

Siddiq AM, Atmowidi T, Qayim I. 2015. The diversity and distribution of Holothuroidea in shallow waters of BaluranNational Park, Indonesia. Biodiversitas 17: 55-60. A study of the diversity and distribution of sea cucumber (Holothuroidea)Â&nbsp;in shallow waters at Baluran National Park, East Java, Indonesia was carried out from July until September 2015. The method used in this studywas systematic transect in low tide condition. Samples were collected by hands at intertidal sites. Identification of sea cucumber speciesÂ&nbsp;based on morphological ossicles. Twenty one species of Holothuroidea belonging two orders and four families were found in this study.Â&nbsp;The most dominant family found was Holothuriidae (16 species),Â&nbsp;Â&nbsp;followed by Stichopodidae (2 species),Â&nbsp;Synaptidae (2 species), andÂ&nbsp;Chiridotidae (1 species).Â&nbsp;Four species (Holothuria olivacea, H. verrucosa, Labidodemas rugosum, and Chiridota smirnovi) are new record for Java waters and one species (H. papillifera)Â&nbsp;is a new record for Indonesian waters. Two morphospecies (H. aff. macroperona and Stichopus cf. monotuberculatus) need reconfirmation to species level. The highest abundance species of Holothuroidea was found at under rock with 15 species. Whereas, the highest number of individuals was found in seagrass areas with 5457 individuals. H. atra has extensive habitat distribution, such as seagrass, macroalgae, coral reef, dead coral, sand, and under rock.

Abstract

The objective of this study was to found the composition and structure of vegetation at the upstream Cianjur Watersheds. Research sampling conducted by using plot method placed purposive random sampling at research location with increase elevation equal to 100 m from sea level. Every 100 m elevation level, were taken 5 sample plots so that up to 1000-1500 (sub-montana zone) totalize plot were 30. Measured parameter cover density, frequency, dominancy, Important Value Index (IVI), Diversity Index (H'), and Evenness (E). The subdividing pattern plot done through cluster analysis. The result of this research indicate that species puspa (Schima wallichii) and rasamala (Altingia excelsa) were two species with highest Important Value Indeks, so that both species considered to be dominant the community. The species diversity index (H’) equal to 3,38 categorized to high, but the evenness value (E) was categorized to low (1.95). The phenomena happened because tha distribution of species were heterogenous. The Cluster analysis indicated that there were three sub-groups which can be categorized as sub-zone in sub-montana zone, namely the sub-zone lower, middle and hight. © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: vegetation analysis, Upstream Cianjur watersheds, Sub-montana zone, Mt.Gede-Pangrango National Park’s.

Abstract

Rahman FA, Qayim I, Wardiatno Y. 2018. Carbon storage variability in seagrass meadows of Marine Poton Bako, East Lombok, West Nusa Tenggara, Indonesia. Biodiversitas 19: 1626-1631. The increase of atmospheric CO2 concentration in the last decades leads to global warming, having an adverse effect on the environment condition on the Earth. One of the natural mechanism as an effort to reduce the impact of global warming is carbon absorption and storage through photosynthesis mechanism of seagrass vegetation. Research conducted at Poton Bako, a district in East Lombok was aimed to reveal the composition of seagrass species, density, seagrass coverage, the biomass of seagrass tissue, content of carbon storage in seagrass tissue (above and below substrates), carbon content in seagrass sediments, and estimation of carbon stock in the area. The research included observation of species composition, and the sample was collected from 0.5 m × 0.5 m plot area. The total plot area was 36 on six lanes with the space between plots 25 m and between lanes 100 m. Six species from two families were found in the seagrass meadows, i.e., Cymodocea rotundata, Enhalus acoroides, Halophila minor, Holodule uninervis, Thalassia hemprichii and Thalassodendron ciliatum. The three highest total densities were C. rotundata 214.67±110.469 stands m-2, T. hemprichii 85.11±41.471 stands m-2, and H. minor 42.22±44.204 stands m-2. Species with the highest coverage value at all observation plots was C. rotundata (33.47±26.748 %), and T. ciliatum had the lowest value (2.12±5.071 %). The total biomass was 676.32 g DW m-2 with biomass above substrate 329.94±57.725 g DW m-2 and below substrate 654.88±81.199 g DW m-2. The carbon content of substrate ranged from 0.11% to 0.51% with the average of 0.35±0.081%, which was categorized low. The total average of carbon storage in seagrass was 447.92 g C m-2 comprising 142.77 g C m-2 of their tissue above substrate and 305.15 g C m-2 below substrate. Regarding the area, the total carbon stored in seagrass meadows with 56.65 ha area was 249.27 t C ha-1.

Abstract

Basalamah F, Utami-Atmoko SSU, Perwitasari-Farajallah D, Qayim I, Sihite J, Van Noordwijk M, Willems E, Van Schaik CP. 2018. Monitoring orangutan reintroduction: Results of activity budgets, diets, vertical use and associations during the first year post-release in Kehje Sewen Forest, East Kalimantan, Indonesia. Biodiversitas 19: 689-700. Pongo pygmaeus morio, a subspecies of orangutan founded east Kalimantan is steadily declining and classified as endangered. A reintroduction program was recently established. We monitored the reintroduced individuals during their first year post-release at Kehje Sewen Forest in East Kalimantan to document the adjustment to their new habitat. Here, we present a report on the activity patterns, food choice, travel height, nest-building abilities and associations of six individuals ranging between eight and thirteen years old. Our results show that all individuals survived their first year. They spent most of their time feeding and had a largely frugivorous diet, similar to wild orangutans. However, although they were able to build nests, they reused or rebuilt old nests more often than expected. They also spent 16% of their total activity time on the ground, more than expected. This information will contribute to attempts to evaluate factors affecting the adjustment process, and thus optimizing future reintroduction procedures.

Abstract. Master J, Qayim I, Setiadi D, Santoso N. 2020. Autecology of Melastoma malabathricum, an invasive species in the Way Kambas National Park, Indonesia. Biodiversitas 21: 2303-2310. Melastoma malabathricum has become one of the invasive plants in the Way Kambas National Park (WKNP), Lampung, Indonesia. This plant is feared to be a problem in efforts to conserve biodiversity in the WKNP area. Therefore, this study aimed to analyze the factors causing the invasion of these plants. The vegetation analysis plot was placed on three types of habitats in the study location, namely, forests, swamps, and invaded swamps, then measurements and records of vegetation data and abiotic factors were recorded in each plot. The results reveal that M. malabathricum dominates swamp habitat and negatively associated with trees, which can provide canopy. Abiotic factors, such as canopy cover, water level, and soil fertility, become supporting factors for the invasion. In addition, climate change, which is causing drought also contributes to the invasion of M. malabathricum at the WKNP.

Abstract. Wahdina, Setiadi D, Purwanto Y, Qayim I. 2021. Natural dye plants used by Dayak Iban in Sungai Utik, Kapuas Hulu, West Kalimantan, Indonesia. Biodiversitas 22: 1397-1404. &nbsp;Natural dye plants used by indigenous people in Indonesia are considered an important and unique gene pool, especially in Kalimantan (Indonesian Borneo), known to have high biodiversity and endemicity. Dayak Iban people in Sungai Utik, Kapuas Hulu District, West Kalimantan Province, Indonesia&nbsp; are considered a culturally important group, recognized by their customary forest and harmonious living with nature. One of the traditional knowledge practiced by this group is the use of dye plants for along time to make traditional woven fabric and various plaiting handicrafts. This study aims to investigate the types of natural dye plants used by the Dayak Iban people in Sungai Utik, and how the local people use them traditionally. Information about the dye plants used and their utilization process was obtained through in-depth interview methods. We also identified the color produced by the dye plants. There were 15 plant species used as dye plants in Sungai Utik Village. The dye plants are used for plaiting and yarn dyeing as traditional woven material with white, red, and black colors are the only colors used. The most important dye plants are engkerebai kayoh (Psychotria malayana) for red dye color and rengat kikat (Clerodendrum laevifolium) for black dye color. The coloring process includes the yarn oiling, tying, measuring, dyeing, and drying, followed by weaving process. The people in Sungai Utik obtain the dye plants in their customary forest as they keep their forests as a highly valuable treasure.

Abstract. Putri WU, Qayim I, Qadir A. 2021. Invasive species in the soil seed bank of two limestone hills in Bogor, West Java, Indonesia. Biodiversitas 22: 4019-4027. Study on the impact of invasive species on plant communities has been conducted mainly on the aboveground vegetation. The impact on the soil seed bank has received less attention mostly due to practical difficulties in conducting seed bank assessment. Evaluation of seed bank composition is useful in detecting invasive plant species that may have been present as buried seeds. Information on the vegetation composition in Nyungcung and Kapur hills both under and aboveground is available, but specific information on invasive species has not been discussed yet. This paper describes and analyzes the structure (composition and density) of invasive species in the soil seed bank. Eighty soil samples were taken from the study sites. The soil seed banks were analyzed using seedling emergence and seed extraction methods. 2602 and 1280 seedlings emerged from soil seed bank of Nyungcung and Kapur hills, respectively. From that number, approximately 48.96% and 68.51% of the seedlings are invasive species in the soil seed bank of Nyungcung and Kapur hills. The invasive species were dominants in the soil seed bank of the two sites. Cecropia peltata and Clidemia hirta were the most abundant invasive species in the Kapur and Nyungcung hills seed bank, respectively. Species richness and seedling density were higher in Nyungcung hills than Kapur hills, which were invaded for a relatively longer period.

Abstract. Arko PF, Sudirman LI, Qayim I. 2021. Changes in landscape ecology between nature reserve and palm oil plantation in West Java, Indonesia based on the observations of macrofungal population. Biodiversitas 22: 4526-4537. As the biggest tropical country in Southeast Asia with the third-largest forest, Indonesia has limited data on macrofungal diversity. The limitation of the data is due to the lack of study on macrofungi in high biodiversity locations such as Dungus Iwul Nature Reserve (CADI). The purpose of this study was to determine and analyze the population of macrofungal species caused by the conversion in landscape structure (fragmentation and land-use change) that occurred in CADI patch and oil palm plantation of PT Perkebunan Nusantara VIII (PTPN) matrix, Cigelung, West Java. The sampling method used was opportunistic sampling assisted by line intercept. The macrofungal identification was based on morphological characters. The analysis of community ecology was performed in R programme. The results showed that macrofungal population and diversity in CADI were the highest, followed by PTPN planted in 2004 and planted in 2003, with a significant difference among the three study locations. The community dominance index shows the opposite, with the highest in PTPN 2003 and the lowest in CADI. These results showed changes in macrofungal population and diversity from the conversion in landscape structure. There were eleven indicator species in CADI, two species in PTPN 2003, and five species in PTPN 2004.
