Abstract

The vegetation and wildlife of Gunung Halimun Salak National Park (GHSNP) are quite diverse. Ants (family: Formicidae) are among the diversity's less studied components. The hilly terrain of Gunung Halimun Salak National Park has not seen considerable alterationOne of the more fascinating aspects of studying wildlife is insects, particularly ants. Research on ants in the mountains at different elevations has been scarce up to this point. The purpose of this study is to examine the ant community at seven different elevations in terms of abundance, variety, and community similarity and to determine how ant diversity and environmental factors relate to one another. The soil arthropods were collected using pitfall traps, placed in several altitudes, i.e., 500 m, 700 m, 900 m, 1100 m, 1300 m, 1500 m, and 1700 m . Overall, 1536 ants were measured for abundance throughout all high-altitude habitats. At 700 m, the greatest number of arthropods (365 individuals) was found. There were just 85 ants at the maximum elevation of 1700 meters, which was the lowest ant abundance. The dominant morphospecies of the order Hymnoptera/ants (Formicidae) were Pheidole sp. and Polyarchis sp.

Abstract

The decline in productivity of Acacia seedlings (Acacia crassicarpa) in Industrial Plantation Forests is caused in part by attacks of mealybug pests (Paracoccus marginatus). Using chemical insecticides in pest control can negatively impact health and the environment, so more environmentally friendly alternatives are needed, such as plant-based insecticides. This study aims to determine the concentration of noni leaf extract on the mortality of mealybug pests. A completely randomized design (CRD) was employed, consisting of four treatments with different concentrations of Morinda citrifolia leaf extract (30 g/l, 40 g/l, 50 g/l, and 60 g/l), each replicated three times. The observed parameters included the time of initial death, Lethal Time 50 (LT₅₀), and total mortality percentage. The results indicated that the use of Morinda citrifolia leaf extract of 60 g/l was the most effective, with an average time of 8,67 hours, LT₅₀ of 24,67 hours, and total mortality rate of 100% for Paracoccus marginatus.

Abstract

The existence of forests for village communities cannot be separated from the survival of communities around the forests. Utilization of environmental services in forest areas can take the form of ecotourism potential developed in the region. Ecotourism also embraces the use of environmental services in protected forest areas, including the Damaran Baru protected forest area. The current problem is that there is not yet optimal management of existing natural resource potential in order to support ecotourism development. The aim of this research is to analyze the potential supply and demand for ecotourism in the Damaran Baru protected forest area and to analyze the sustainability of ecotourism in the Damaran Baru protected forest. The research results obtained for supply potential data identified 12 ecotourism potentials in the form of coffee plantations in the area, waterfalls, primate monitoring posts, hot springs, bird monitoring posts, camping ground areas, pitcher plants, savanna, orchid beds, heli rocks, edelweis beds. and the peak of Damaran Baru. Likewise, for demand potential, it was obtained in terms of facilities and infrastructure that require improvement to attract more visitors. The results of the ecotourism sustainability research show that the level of visits to ecotourism locations has started to increase with a total of 200 visitors in 2022, where there was an increase in the number of visitors of 53.85% from the previous year.

Abstract

The high production of sawn timber has increased the demand for wood each year. This has created an imbalance between the growing demand for wood and the declining supply of wood from natural forests. To address this issue, innovations in wood engineering are necessary to meet future wood demand. One solution is to utilize wood to produce Glued Laminated Timber (glulam). This research uses sengon and red meranti wood, forming three models: Model A, Model B, and Model C, with sizes of 120 x 5 x 1 cm and 120 x 3 x 1 cm. The objective of this study on glulam from sengon and red meranti wood is to determine the characteristics of its physical and mechanical properties. The highest density for physical properties is produced by Model B glulam, which is 0.579 g/cm3, the highest moisture content is produced by Model C glulam, which is 14.43%, delamination in cold water ranges from 12.08% to 32.08%, and in boiling water ranges from 22.25% to 44.63%. The highest MOE and MOR tests are shown by Model B and Model A. The results obtained for the MOE of Model B are 10,960.194 MPa and the MOR of Model A is 74.677 MPa.

Abstract

High conservation value (NKT) is an assessment of outside conservation areas, including aspects of biodiversity, environmental services, and community social culture. This research aims to identify HCV potential at the village level. This research was conducted in Kedungpomahan Wetan, Kedungpomahan Kulon, and Tlogoguwo, Purworejo Regency. Structured interviews with key people in the village were conducted to obtain information about the HCVs in the village. Remote sensing approaches are also used to confirm potential HCVs. Based on the analysis results, it was found that potential HCVs were HCV 4.1, 4.2, and 5 in the three research villages, HCV 1.2 and 6 were found in Kedungpomahan Wetan and Kedungpomahan Kulon Villages, HCV 1.3 potentially existed in the three villages, and HCV 1.4 potentially existed in Tlogoguwo Village. The biodiversity aspect shows the discovery of endangered species, namely the pangolin (Manis javanica) and the slow loris (Nycticebus javanicus), which have Critically Endangered status. Aspects of environmental services are also found in the three villages, namely as flood control areas and preventing erosion. In the socio-cultural aspect, the area provides basic basic needs for the community, namely clean water and two graves. Knowing the potential of areas with high conservation value at the village level highlights the importance of management at the village level. This can be a basis for input in creating biodiversity management programs by related agencies such as the Ministry of Environment and Forestry and private agencies.

Abstract

Forest degradation in river basins can cause soil erosion and landslides in upstream areas, as well as flooding in downstream areas, thereby expanding critical land areas. To reduce the extent of critical land, comprehensive forest and land rehabilitation efforts must be undertaken with the involvement of multiple stakeholders. Activities conducted in Tapung Sub-district, Kampar Regency include reforestation of the Imbo Putui Traditional Forest area, seedling planting along the Tapung River, roadside planting, school ground plantations, and similar initiatives. This research aims to identify the roles of various stakeholders in forest and land rehabilitation (RHL) activities in Tapung Sub-district, Kampar Regency. This study employs qualitative methods, collecting data through observation, in-depth interviews, and documentation studies to obtain both primary and secondary data. Data analysis was conducted using descriptive qualitative techniques. The research findings reveal that multiple stakeholders are involved in forest and land rehabilitation activities. Forest farmer groups play an implementation role in community nursery and village nursery programs to provide seedlings required for forest and land rehabilitation activities, with funding facilitated by BPDASHL Indragiri Rokan, which serves as the program initiator and supervisor. DLHK Riau Province and KPH Suligi Batu Gajah function as coordinators and facilitators in seedling procurement and distribution to communities. KODIM 0313/KPR serves as protector and activity supervisor. Community-based forestry extension officers act as catalysts, mediators, motivators, and educators within the community. Private companies also contribute as financial and material supporters through corporate social responsibility program implementation.
