Abstract

The success of stingless beekeeping was determined by site suitability and the availability of floral sources. Bee forage was also an important requirement used to improve the qualities and quantities of its products. Information about specific forage plants in different land uses was needed to make the plants sufficient. Therefore, this study aimed to examine forage preference for stingless bees in different land use areas. The location used was categorized into three types, namely agroecosystems, forests, and settlements. The pollen samples were analyzed with acetolysis and then identified. The results showed four species of stingless bees, namely Tetragonula fuscobalteata, T. laeviceps, and T. clypearis, as well as Heterotrigona erythrogastra. T. fuscobalteata was mostly cultivated in the settlements, T. laeviceps and T. clypearis were cultivated in the agroecosystems, while H. erythrogastra was mostly found near the forest. The identification of pollen showed that the favorite feed plants of Tetragonula were Bromeliaceae and Cyperaceae, while the forage preference for H. erythrogastra was Rubiaceae. The Principal Component Analysis revealed that the bees' preference was influenced by the availability of forage sources. Based on the results, stingless bees did not have specific forage plants, but foraging was often carried out to provide an abundance.

Abstract

Social forestry programs, including village forest schemes, were anticipated to increase the local community income, but the implementations often differed from the plans. Therefore, this research aimed to determine the attitude and behavior of LPHD members toward village forest management in Central Sulawesi by analyzing their beliefs and evaluation values. The results showed that the forest attribute had the highest value, which indicated that the village forest offered numerous opportunities to enhance the community's welfare. In addition, the attitude value was consistent with the behavior analysis, resulting in a positive value of 0.74. This value indicated that LPHD members agreed with the village forest management in Central Sulawesi and actively participated in the implementation.

Abstract

The Semama Island Wildlife Sanctuary (SIWS) was part of the Derawan National Tourism Strategic Areas (NTSA) with great potential. As a conservation area, tourism should consider the carrying capacity at SIWS for its optimal development. Therefore, this study aimed to estimate the carrying capacity of the SIWS area using the Physical Carrying Capacity approach. Literature studies, field observations, and interviews were conducted in October 2021 to collect data. The results showed that the pyhsical carrying capacity of the SIWS was 506 people per day, consisting of 45 mangrove tours, 401 snorkeling, and 60 birdwatching activities, indicating the maximum number of visitors the SIWS could accommodate. This information is essential as a consideration for future tourism development.

Abstract

Bidara Laut (Strychnos lucida R.Br.) has the potential as a medicinal plant in West Nusa Tenggara, but its cultivation encountered many challenges. Mount Tunak, Natural Tourism Park, had similar environmental conditions to the natural habitat of Strychnos lucida and was selected as the location for planting trials. Given the dry climate, high temperature, and soil fertility limitations, the trials applied soil amendments, such as hydrogel, mycorrhizae, mulch, and fertilizer, to enhance the growth. This research aimed to investigate the effects of soil amendments on the survival rate of Strychnos lucida. This research used a Randomized Complete Block Design (RCBD) with four treatments and one control. The treatments included applying five grams of hydrogel, five grams of mycorrhizae, 1 m x 1 m of plastic mulch, and a combination of all three. The research used 15 replication blocks, each with an area of 450 m2 and a spacing of 3 m x 3 m. Each block included ten replication plants (in total 750 plants), and the trial lasted 19 months. The results showed an insignificant growth increase after 19 months of planting in all treatments. There were improvements in survival rate, height growth, and diameter growth by 25%, 85%, and 25%, respectively.

Abstract

The continuous decrease in green open spaces due to urban development leads to harmful environmental problems for communities. Land scarcity is one of the significant reasons for the difficulty in urban forest development in riparian areas. The development of riparian urban forests serves a dual purpose, namely preserving the natural riparian function for vegetation and increasing the green open space area size. Therefore, this study aimed to analyze the riverside community's understanding and views on urban forests and their perceptions of riparian urban forest development. Data were collected through questionnaires and interviews and analyzed using descriptive statistics. Approximately 63.64% and 96.97% of the respondents understood and viewed the urban forests well. Furthermore, 90.91% of the respondents agreed with the riparian urban forest development. Generally, 66.67% agreed to create greener, tidier, cleaner, and more beautiful riparian areas to attract tourists. The positive perception of the community regarding the urban forest development in riparian areas became a rational basis to sustain its function and increase the size of urban forests and green open space areas.

Abstract

Mangrove forest ecosystems resources could serve as income sources for the surrounding communities. However, the total economic value of these resourceshas yet to be recognized, calculated, and considered in managing and conserving mangrove forest ecosystems. This research aimed to estimate the direct economic value (timber, charcoal, aquatic biota, processed products, honey, and Nypa roof), indirect economic values (abrasion prevention, carbon stock, oxygen production, intrusion barrier), and optional economic value (biodiversity) of mangrove forest ecosystems. This research used two assumptions to calculate the total economic values: with and without timber utilization activities for charcoal production in the Unit XXXIII Kubu Raya Forest Management Unit (FMU). The results indicated that the indirect economic value had the highest percentages compared to the direct and optional economic values in both assumptions.

Abstract

The quality of timber could be affected by timber hauling, primarily when it remained in the forest and became vulnerable to pests and fungi attacks. Additionally, road conditions could also influence the slickness of hauling. Therefore, this study aimed to identify the effect of road conditions on hauling performance, cost, and soil deterioration. This research analyzed four types of road conditions in Acacia mangium plantations in West Java and Banten, including dry, wet, uphill, and downhill roads. The results indicated that the average hauling performance of 6.604 m3km/hour on the uphill road was the least among all road types. The uphill soil road had the highest average hauling cost of 30,685 IDR/m3km and the deepest average rut of 17.503 cm compared to others. These results would provide better information on low-cost and environmentally friendly timber hauling productivity.

Abstract

Biodiversity measurement served as baseline data for the development of effective conservation plans. The accuracy of the measurement was highly dependent on the size of the sample plot. Even though Indonesia had various ecosystems, the standard sample plot size for measuring plant species diversity was only available for lowland, lower montane, and mangrove forests. Therefore, this study aimed to determine the optimal dimension of plots for measuring plant species diversity in coastal forest ecosystems. The data was collected in Ujung Kulon National Park using various dimensions of sample plots ranging from 2 m × 2 m to 150 m × 50 m. Furthermore, the rarefaction method and species-area curve were used to examine the data. The curves showed that the optimal sample plot dimensions for seedling, sampling, and pole levels were 110 m × 50 m and 150 m × 50 m for tree stages.

Abstract

The Petungkriyono protected and production forests qualified for the Essential Ecosystem Area (EEA). Perhutani manages the area, covering approximately ±7,683.33 hectares, with 80% being secondary natural forests and the habitat for endangered flora and fauna. This research aimed to analyze the suitability of Petungkriyono EEA for biodiversity preservation, protection, sustainable use, and ecosystem restoration using carrying capacity based on ecosystem services (CCES). This research used a participatory approach and expert opinion with a weighting sum on land cover and landscape variables. The results showed that approximately 74.12% of the Petungkriyono AAE candidate had high and very high CCES classes and were suitable for biodiversity and area protection priorities. Meanwhile, 14.35% was in a low class and suitable for ecosystem restoration and sustainable use priorities.
