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.
马钱子(Strychnos lucida R.Br.)在西努沙登加拉有作为药用植物的潜力,但其栽培遇到了许多挑战。自然旅游公园图纳克山的环境条件与马钱子的自然栖息地相似,因此被选为种植试验地点。考虑到干燥的气候、高温和土壤肥力的限制,试验使用了土壤改良剂,如水凝胶、菌根、地膜和肥料,以促进生长。本研究旨在探讨土壤改良剂对马钱子(Strychnos lucida)存活率的影响。本研究采用随机完全区组设计(RCBD), 4个处理和1个对照。处理方法包括使用5克水凝胶,5克菌根,1米× 1米的塑料覆盖物,以及三者的组合。该研究使用了15个复制块,每个块的面积为450平方米,间距为3米× 3米。每组10株(共750株),试验期19个月。结果表明,种植19个月后,各处理的生长均无显著增长。成活率、株高和株径分别提高25%、85%和25%。

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.
红树林生态系统资源可以作为周边社区的收入来源。然而,在管理和保护红树林生态系统时,这些资源的总经济价值尚待确认、计算和考虑。本研究旨在评估红树林生态系统的直接经济价值(木材、木炭、水生生物群、加工产品、蜂蜜和Nypa屋顶)、间接经济价值(耐磨性、碳储量、氧气生产、入侵屏障)和可选经济价值(生物多样性)。本研究使用了两个假设来计算总经济价值:在第三十三单元库布-拉亚森林管理单元(FMU)中,有和没有用于木炭生产的木材利用活动。结果表明,在这两种假设中,与直接经济值和可选经济值相比,间接经济值的百分比最高。

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. tree stages.

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.
木材的质量可能会受到木材运输的影响,主要是当木材留在森林中,容易受到害虫和真菌的攻击时。此外,道路条件也可能影响运输的平稳性。因此,本研究旨在确定道路条件对运输性能、成本和土壤退化的影响。本研究分析了西爪哇和万丹的Acacia mangium种植园的四种道路条件,包括干燥、潮湿、上坡和下坡道路。结果表明,在所有道路类型中,上坡路上6.604 m3km/h的平均牵引性能最低。与其他道路相比,上坡土路的平均运输成本最高,为30685印尼盾/立方米公里,平均车辙最深,为17.503厘米。这些结果将为低成本和环境友好型木材运输生产力提供更好的信息。

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. 
由于城市发展,绿色开放空间的持续减少给社区带来了有害的环境问题。土地稀缺是造成河岸地区城市森林开发困难的重要原因之一。河岸城市森林的开发具有双重目的,即保护植被的自然河岸功能和增加绿色开放空间面积。因此,本研究旨在分析河岸社区对城市森林的理解和看法,以及他们对河岸城市森林发展的看法。通过问卷调查和访谈收集数据,并使用描述性统计进行分析。约63.64%和96.97%的受访者对城市森林有较好的理解和看法。此外,90.91%的受访者同意河岸城市森林的发展。总体而言,66.67%的人同意创建更绿色、更整洁、更清洁、更美丽的河岸区来吸引游客。社区对河岸地区城市森林发展的积极看法成为维持其功能和增加城市森林和绿色开放空间面积的合理基础。

The increasing number of hydrometeorological disasters induced by unsustainable landscape management has led to significant fatalities and economic loss. Forest ecosystem landscapes are strategic national capital that could contribute to climate change mitigation. The government had formulated policies on Folu Net Sink ~2030  through sustainable forest management, environmental and carbon governance, and a Nationally Determined Contribution (NDC) strategic approach using its natural infrastructure in the form of forest ecosystem landscapes. The government could establish attractive and integrated incentive and disincentive systems and mechanisms with sustainable forest management to achieve the targets.
不可持续的景观管理导致的水文气象灾害数量不断增加,造成了重大的死亡和经济损失。森林生态系统景观是有助于减缓气候变化的战略性国家资本。政府通过可持续森林管理、环境和碳治理,以及利用森林生态系统景观形式的自然基础设施的国家自主贡献战略方法,制定了2030年福卢净汇政策。政府可以通过可持续森林管理建立有吸引力的综合激励和抑制系统和机制,以实现这些目标。

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.
Petungkriyono保护区和生产林符合基本生态系统区(EEA)的要求。Perhutani管理着该地区,面积约为±7683.33公顷,其中80%是次生林和濒危动植物的栖息地。基于生态系统服务功能(CCES)的承载力分析Petungkriyono EEA对生物多样性保护、可持续利用和生态系统恢复的适宜性。本研究采用参与式方法和专家意见,对土地覆盖和景观变量进行加权求和。结果表明,约74.12%的Petungkriyono AAE候选物种具有高和非常高的CCES等级,适合生物多样性和区域保护优先级。14.35%属于低等级,适合生态恢复和优先可持续利用。

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. 
Semama岛野生动物保护区(SIWS)是德拉旺国家旅游战略区(NTSA)的一部分,具有巨大的潜力。作为一个保护区,旅游业应考虑SIWS的承载能力,以实现其最佳发展。因此,本研究旨在使用物理承载力方法来估计SIWS区域的承载力。2021年10月进行了文献研究、实地观察和访谈,以收集数据。结果显示,SIWS的地理承载能力为每天506人,包括45次红树林之旅、401次浮潜和60次观鸟活动,这表明SIWS可以容纳的最大游客数量。这些信息对于未来旅游业发展至关重要。
