The vegetative clonal teak is fast-growing, exhibits relatively uniform growth, and is sensitive to crown competition. The crown width dimension correlates positively with the size of the diameter (CW allometry). We investigated the effects of competition on CW allometry for dominant trees on good sites and the prediction accuracy of CW allometry. The data were measured during 2015–2017. The Hegyi index with a fixed 30° search cone method was used to measure competition. The scatter plot of all observations was used to identify the general pattern of CW over diameter, and competition index with both diameter and CW. The data were classified into three groups, ignored, free, and occurred competition data sets. Moreover, the occurred competition data set was categorized into three levels: low, medium, and heavy. The power model was used for parameterization of CW allometry. The dispersion of CW over diameter for all observations exhibited a moderate positive correlation, as well as the competition index with both diameter and CW. For the ignored-competition data set, the CW allometry was able to describe approximately 37.2% of observed CW. Interestingly, however, the prediction accuracy increased to 44.6% for the free competition data set. In contrast, the capability of the CW allometry for the occurred competition data set declined sharply to 9.1%. Among the occurred competition data sets, the heavier the subject trees competed, the lower the CW allometry explained the variations. However, the CW allometry was completely not able to describe the observed CW in the heavy competition level.

Various rehabilitation and restoration of mangrove forests have been done, but there have not been any significant results. The main reason for the various failures in this activity is that the effort is not based on scientific data such as the suitability of the physicochemical conditions of mangrove habitats along the beach coast of Sulamo District. The purpose of this research is to analyze the condition of salinity, the thickness of mud, and the beach slope of the selected mangrove locations Oeteta, Pariti, Beringin, and Pitai beaches. The salinity conditions show variations, ranging from 19 ppm to 42.33 ppm. The thickness of the mud shows the highest value at 79.11 cm and the slope of mangrove coastal 1–4%. This research shows that the condition of the mangrove ecosystem in the coastal district of Sulamo is still suitable for mangrove growth. This research provides a basic overview of mangrove ecosystem conditions located on the beach coast of the Sulamo district as the basis for planning rehabilitation programs and mangrove restorations in the research area.

Rattan is the most important non-forest timber product utilized by communities adjacent Lore Lindu National Park (LLNP). The establishment community conservation agreement (CCA) in 2001 was unable to prevent rattan depletion. Then, a local institution called community conservation partnership (CCP) has been recently proposed. Therefore, the objective of this study is to explore how to craft a local institution of CCP for sustainable rattan governance in LLNP using Social-Ecological Systems (SES) Framework. The study was conducted in LLNP area and Ngata Toro, a buffer zone village of LLNP. We conducted rattan inventory and collected social data by interview for analyzing CCP development using SES framework. The results showed that CCP is most likely to be successful in implementing due to several reasons. Firstly, the establishment of constitutional-choice rules made clear the nested enterprise. Secondly, the reallocation of CCP location to the traditional zone increase the boundary clarity. Thirdly, transferring rights to the Ngata Toro community will make effective co-management, increase the legitimacy of rattan utilization, decrease potential conflicts among resource unit users and reducing monitoring cost. Finally, deciding the rattan harvesting quota will ensure the rattan ecological and livelihood sustainability. With the clarity of system boundaries and property rights, we argue that CCP institutions will bring many benefits in many ways. Overall, most variables of SES framework can be used to analyses the readiness of CCP institutional arrangement for sustainable rattan management in LLNP.

Fertilization is one of the nutrient management efforts that play an important role in improving the productivity of plantation forests. It was conducted to provide adequate nutrients for the plant at the initial growth period when the availability of soil nutrients is very limited. The optimum dose of fertilization for each plant is different depending on its requirement, climate, and soil properties. This study investigated the influence of fertilization on early growth, aboveground biomass, carbon storage, and leaf characteristics in Eucalyptus pellita in the sixth months after field establishment. An experiment comprising four treatments of fertilization, i.e., 0, 75, 133, and 167 kg ha -1 of triple superphosphate 46% P2O5 was set up using randomized complete block design with five replications. Four indicators were selected to evaluate the early growth of E. pellita, namely survival rate, height, the collar of diameter, and crown projection area. Aboveground biomass and carbon storage of E. pellita were estimated in each component, covering stem, bark, branches, and leaves. The leaf characteristics of E. pellita were described by individual leaf area, individual leaf dry weight, specific leaf area, and leaf area index. Results showed that the different treatment of fertilization did not have a meaningful effect on survival rate, individual leaf area, and specific leaf area. The treatments presented a substantial effect on other indicators such as height, diameter, crown projection area, aboveground biomass, carbon storage, individual leaf dry weight, and leaf area index. Despite the fact that the highest mean of height and collar of diameter were observed in the dose of 167 kg ha -1, the greatest average of aboveground biomass and carbon storage were noted in the rate of 133 kg ha -1. Nevertheless, this study did not find a highly different performance of E. pellita between both treatments statistically.

Mount Rinjani (3726 masl) is the second-highest volcano in Indonesia with a newer active volcano called Mount Barujari (2376 masl) inside its crater. The mountain has become the center of tourist destinations in West Nusa Tenggara Province, with hiking as the most popular activity carried out by visitors. This study aimed to identify physical and biological hazard potentials and activities that may put visitors at risk to prepare hazard management recommendations. We carried out an interview and field observation for the study in April 2018. We used the United Nations Environment Programme (UNEP) risk assessment as a reference in biological and physical hazard analysis, and the National Patient Safety Agency for human activities. We also used ArcGIS 10.1 software to develop a map of hazard potentials. Cliff (physical hazard), tree roots (biological hazard), and running (activity) were hazards with the highest risks. All four management options offered by the UNEP, i.e., reducing risk, accepting the tolerable risk, avoiding risk, and transferring risk, were applicable in this area. We proposed that the management considering to increase local community and visitors' knowledge of hazards as a preventive measure while continuing to provide repressive measures.

Indonesia and Philippines are homes of biodiversity in Southeast Asia. In recent years, however, there has been a decline in biodiversity brought about by land use change. This condition poses threat on the food security of communities around the watersheds. The type and volume of main food items depend on the ecological and physiological conditions of the watersheds, in this case, Way Betung and Molawin Dampalit. When edible food is sufficient and available in an area, there is higher livelihood that the communities are food secured. This paper argues based on research which has been conducted in May to November 2015 that the food security of communities in the selected agroforestry landscapes in Way Betung and Molawin Dampalit have moderate. Levels of its food security based on four dimensions, namely: food availability, food accessibility, food stability and food utilization. Amounted 261 Indonesia farmer’s respondents and 106 Philippine’s respondents mentioned that the farm households generally practice agroforestry where the production of short-term and medium-term agricultural crops, woody perennials and livestock are deliberately combined. The type of crops grown by the farm households contribute to the level of food security.

The establishment of the Morotai Island Regency as one of the 10 National Tourism Strategic Areas and Special Economic Zones is a central government strategy to accelerate the development of regencies/cities in North Maluku Province, which are still classified as underdeveloped regions in Eastern Indonesia. This study aims to analyze the influence of tourist arrival rate, price, human development index, and tourism promotion policy on economic growth by using regression of panel data of fixed-effect model (FEM) based on the feasible generalized least square (FGLS) VI method in eight regencies/cities in North Maluku Province during the period of 2012–2017. This finding shows that tourism development was closely related to economic growth, both in the short and long term. However, the development of tourism facilities and other supporting tourism facilities on the coast by coastal landfill had sacrificed the growth of coastal mangrove forests. Therefore, the local government is encouraged to issue regional regulations on the implementation of sustainable tourism businesses and educate the local community and visitors to play a role in protecting the environment of tourist destinations sustainable.

A guild is a group of species that have similar requirements of resource and foraging behavior. The knowledge of insectivorous guild could explain foraging patterns, niche exploitation, and competition in a tropical forest. This information could help to monitor the forest by understanding the guild composition and their response to the habitat condition. In order to describe the guild composition and niche overlap of insectivorous birds, we observed all of the individual birds found foraging in the evergreen forest, Baluran National Park. Bray-Curtis similarity index and Pianka niche overlap index were used to analyze the data and grouping the birds into a guild. The cluster analysis consists of 27 bird species revealed 4 guilds: ground gleaner, foliage gleaner, aerial sallier, and bark prober. Based on species richness, foliage gleaner dominates the other groups while bark prober had the least species richness in the evergreen forest. The scarcities of feeding substrate affect guild existence and proved that the diversity of habitat substrate could affect the diversity of guild in an area. Ten congeneric species were found in this habitat and most of them are grouped into foliage gleaner. The junglefowl has the highest niche overlap than any other congeneric species. It seemed that the more specific the foraging substrate niche, the higher the competition among sympatric species. The level of congeneric/sympatric species competition could become the indicator to monitor a specific habitat or forest by understanding their niche partitioning, especially if the species is protected by the law.

The ownership transfer and conversion of cultural lands are a long-standing crucial issue in the dynamics of tourism development in Bali, so efforts to build a harmonious orientation among stakeholders in creating sustainable cultural land utilizations are important. For that matter, this research was conducted to study the phenomenon of polarization orientation on cultural land utilization of ecotourism development in Bali Aga. The assessment of cultural land sustainability was conducted using One Score One Indicator Scoring System analysis, with research aspects including ownership, economic, ecological, socio-cultural and spatial aspects. Besides, the polarization of stakeholder orientation was measured through perception, motivation, and preference, then, it was analyzed using Kruskal Wallis and Dunn Tests. The results of One Score One Indicator Scoring System analysis showed that the community has implemented various principles of sustainability in the utilization of cultural land in the Bali Aga region. The sustainable cultural land utilization in the Bali Aga region has not been fully achieved because the stakeholder orientation on various aspects and assessment criteria still experience polarization. Although the polarization orientation is still at the level of polarization scale, it can trigger future problems if the polarization is not well minimized by various stakeholder elements.

Traditional agriculture has a relationship with the culture of the local community that is the norms agreed upon by the ancestors related to the use of natural resources to meet the needs of daily life. This article aims to describe the traditional agricultural process of the Wamena people in Jayapura, Indonesia. The perspective used in analyzing traditional agricultural processes was the perspective of sustainable livelihoods of traditional communities in a development context. This research was done in a descriptive-qualitative manner by using primary and secondary data. The primary data was obtained from in-depth interviews. Meanwhile, the secondary data was obtained from observations and document studies. The results indicate that the traditional agricultural process of the Wamena Tribe in Jayapura was able to maintain the livelihoods of traditional communities based on the principles of sustainable development. This could be seen from several stages, such as access to land resources, land ownership, agrarian social relations, and gender issues in the division of traditional agricultural work of the Wamena people in Jayapura. This shows that the local wisdom in the cultural norms of the Wamena people could be used in environmentally friendly agricultural activities that did not have a conflict with the perspective of sustainable development.
