Abstract

The development of Eucalyptus urophylla in dryland ecosystems plays an important contribution to support climate change mitigation and renewable energy diversification. However, the information about the potential of E. urophylla for carbon reduction and energy production is rarely documented, even though it is necessary as fundamental considerations to determine the best strategy for sustainable natural resources management, primarily in dryland ecosystems. This study aimed to quantify the carbon storage and energy production of E. urophylla established in dryland ecosystems at East Nusa Tenggara. The study site is located in a eucalyptus plantation managed by Timor Tengah Selatan Forest Management Unit. Destructive sampling was conducted on 25 sample trees that were evenly distributed from small to big ones. The percentage of carbon content in every tree component, namely stem, branch, and foliage, was determined using elemental analysis, while the calorific value of each tree component was analyzed using a bomb calorimeter. Carbon storage in each component was calculated by multiplying biomass and the percentage of carbon content, while the energy production was computed by multiplying high heating value and biomass from every tree component. The results found the mean carbon storage of E. urophylla in the study site was 55.51 kg tree-1 with a minimum of 6.34 kg tree-1 and a maximum of 184.76 kg tree-1. The percentage of carbon content in the foliage was lower than other tree components by approximately 34.1%. Interestingly, the calorific value of foliage was relatively higher than stem and branch with around 5,252 kcal kg-1. The energy production of E. urophylla ranged from 252.6 to 7,813.3 MJ tree-1 with an average of 2,357.87 MJ tree-1. According to the results, this study concluded the development of E. urophylla in dryland ecosystems demonstrated a meaningful contribution to carbon absorption and energy production at East Nusa Tenggara.

Abstract

Understanding the relationship between soil chemical characteristics and forest productivity is importantly required to support sustainable forest management, mainly in eucalyptus plantation. This study investigated the influence of soil chemical properties on the growth performance of Eucalyptus urophylla which established in dryland ecosystems, East Nusa Tenggara. Forest inventory was undertaken by N-trees sampling in the priority locations for E. urophylla development, located in Buat, Fatukoto1, and Fatukoto2. Four parameters were selected to describe the growth performance of E. urophylla, comprising diameter, height, volume, and mean annual increment. In each sampling point, soil sample was collected at the depths of 0-10, 11-20, and 21-30 cm. Then, the sample was composited before brought to the laboratory for quality analysis. Six parameters were selected to quantify the soil chemical characteristics, namely soil acidity (pH), soil organic carbon (SOC), total nitrogen (TN), available phosphorus (Av-P), exchangeable potassium (Exc-K), and cation exchange capacity (CEC). Results found that soil chemical properties from three locations were significantly different in pH, SOC, Av-P, and CEC. However, this study recorded the content of TN and Exc-K were statistically equal among the three sites. Difference soil chemical properties were also followed by the variation growth of E. urophylla, particularly in diameter and height. The highest volume of eucalyptus stand was observed in Fatukoto1 (181.06+95.46 m3 ha-1), followed by Buat (142.67+27.19 m3 ha-1) and FatukotoII (99.09+62.46 m3 ha-1). There were four soil parameters that meaningfully affected the growth performance of E. urophylla, i.e. pH, Av-P, Exc-K, and CEC. Among those parameters, Av-P demonstrated a consistent effect on the growth performance of E. urophylla. According to these findings, this study concluded that Av-P substantially provided higher effect on the growth performance of E. urophylla than other soil chemical parameters.

Abstract

The establishment of the Eucalyptus urophylla plantation has a potential contribution to the improvement of dryland ecosystem productivity in East Nusa Tenggara. However, the productivity of E. urophylla stand in this area is rarely documented even though it has been managed for more than 20 years. This study was directed to evaluate the growth performance, biomass accumulation, and carbon storage in E. urophylla plantation managed by Timor Tengah Selatan Forest Management Unit (FMU). Data were collected by a field survey using N-trees sampling method. Results demonstrated the mean tree density of E. urophylla in this area was 182 trees/ha with an average stand volume of 150.12 m3/ha. The mean annual increment in volume varied from 1.83 to 19.45 m3/year. The mean biomass accumulation and carbon storage in E. urophylla plantation approached 171.76 and 52.25 Mg/ha. Around 65% of total biomass and carbon storage were accumulated in the stem. Interestingly, the relative contribution of the stem to total biomass increased slowly with diameter class increasing while the dissimilar trend was observed in root, branch, and foliage. Based on the results, this study confirmed that the existence of E. urophylla plantation could increase the productivity of dryland ecosystem in East Nusa Tenggara.

Abstract

Stakeholders with different interests and influences (power) are related to the human-wild elephant conflict mitigation in the Way Kambas National Park in Lampung. Stakeholders need to manage properly to achieve conflict mitigation objectives optimally. This research was conducted in Way Kambas National Park in Lampung. Data were collected with observations, interviews, and related document studies without involving active participations of related stakeholders and data were analyzed by using descriptive qualitative analysis. This research was conducted from September to December 2016. The identification results showed that there were 11 stakeholders dealing with the human-wild elephant conflict mitigation in Way Kambas National Park. The identified stakeholders were divided into three classifications: (1) subject stakeholders coming from farmer groups and people from buffering villages, (2) key player stakeholders consisting of Way Kambas National Park Institution, regional government (village, district and provincial governments), local partners/non-government organizations (Sumatra Forest Conservation and Wildlife Conservation Society-Indonesia Program), Forum Rembug Desa Penyangga/village discussion forums, and Lampung University, and (3) the context setter stakeholder from a private company (PT. Nusantara Tropical Fruit). This research did not find stakeholder from crowd classification. The relationships between stakeholders showed complementary cooperation. The implication of human-wild elephant conflict mitigation management in Way Kambas National Park is that the stakeholder management to build cooperation and collaboration in the form of communication forums to achieve the objectives of human-wild elephant conflict mitigation in Way Kambas National Park is required.Keywords: stakeholder, power-interest matrix, actor-linkage matrix, Way Kambas National Park

Abstract

Community forestry in Babak watershed is one of the efforts to reduce critical land area. The aim of this research was to evaluate the level of community forestry sustainability in both of community forest (HKm) and private forest in Babak watershed. Multidimensional scaling (MDS) was used to analyse the level of community forest sustainability based on the five dimensions of ecology, economy, social, institutional, and technology as well as 29 attributes. Leverage analysis was used to know the sensitive attributes of sustainability, while Monte Carlo analysis and goodness of fit was used to find the accuracy of MDS analysis. The result shows that HKm was in moderate sustainability level (sustainability index 54.08%) and private forest was in less sustainability level (sustainability index 48.53%). Furthermore, the ecology and technology in HKm were classified as less sustainable, while the institution and technology in private forest were considered less sustainable. There were 11 sensitive attributes of HKm and 19 sensitive attributes of private forest. The priorities of attribute improvement in HKm include land recovering (the dimension of ecology) and cooperative development (the dimension of technology). In private forest, the priorities of attribute improvement include leadership capacity building (the institutional dimension) and also the use of silviculture intensive and soil conservation (the dimension of technology).

Abstract

Understanding about social capacital of community has an essential role in supporting the collaborative management of conservation area. This study aims to assess the characteristics of elements of social capital and measure the relationship of the effects of elements of social capital on social capital owned by communities around the buffer zone of Taman Nasional Gunung Ciremai (TNGC). Study site was located in the upstream area of Cisanggarung watershed. Data collection was undertaken through three stages, i.e. literature study, field observation, and inteview. The analysis was conducted using confirmatory factor analysis and descriptive test. The results demonstrated that the social capacital of communities around the buffer zone of TNGC, even though in the same watershed ecosystem unit they had varied characteristics. This fact is proven by the differences in social capital categories and the most influential elements of social capital in the formation of social capital in rural areas that are buffer zones. In order to support the collaborative management in TNGC, the sub-elements of social capital which is at a very weak and weak level, as well as the most influential social capital element in the formation of social capital in each village, should be the main consideration in increasing social capital and preparing conservation collaborative programs that are will be done in each village.

Abstract

Sifat kimia tanah berperan penting dalam mendukung pertumbuhan dan perkembangan tanaman. Sifat kimia tanah dipengaruhi oleh tipe penggunaan lahan dan jenis vegetasi di atasnya. Perbedaan sifat kimia tanah dapat berpengaruh terhadap laju pertumbuhan tanaman sehingga menghasilkan variasi tingkat produktivitas. Penelitian ini mengkaji variasi sifat kimia tanah sebagai dampak pengembangan sistem agroforestri di hutan tanaman kayu putih. Lokasi penelitian terletak di Resort Pengelolaan Hutan Gubugrubuh, Kabupaten Gunungkidul. Sampel tanah dikumpulkan dari 3 petak yang menjadi prioritas penanaman kayu putih yaitu petak 75, petak 78, dan petak 80. Sampel tanah diambil dari lapisan permukaan pada kedalaman 0-15 cm. Indikator sifat kimia tanah yang diuji meliputi pH tanah, C-organik, N-total, P-tersedia, K-total, dan kapasitas pertukaran kation (KPK). Perbandingan sifat kimia tanah dari setiap petak dianalisis menggunakan metode One Way ANOVA (α=0,05) dan dilanjutkan HSD Tukey (α=0,05). Hasil penelitian menunjukkan kemasaman tanah pada setiap petak termasuk kategori agak masam dengan pH 6,00-6,50. Kandungan C-organik bervariasi antara 1,67-3,30%. Nilai N-total berkisar antara 0,13-0,18% sedangkan P-tersedia mencapai 1,50-6,50 ppm. Kadar K-total dan KPK termasuk kategori rendah dengan rentang nilai masing-masing 0,07-0,38 cmolc/kg dan 6,89-13,66 cmolc/kg. Penelitian ini menemukan bahwa N-total merupakan parameter sifat kimia tanah yang berbeda secara signifikan dari setiap petak (p<0,05).
