Abstract

Numerous definitions and concepts regarding ecotourism lead to different implementations in ecotourism policies and systems. Identifying trends between countries provide valuable information for the development of inadequate ecotourism sites. This study aimed to understand the trends in ecotourism policies in Japan, Indonesia, and Australia by examining the bibliographic records of existing ecotourism policy research. These records were retrieved from the Scopus database and processed by using the scientometrics analysis. The results show the significant research trends of ecotourism policy in each country based on the co-occurrence of keywords were "conservation" for Indonesia, "biodiversity" for Japan, and "management" for Australia. Whereas, based on the research field, it revealed a similar priority within ecotourism policy between Australia and Japan in Social Science, while Indonesia in Environmental Science. The pattern of the keyword network analysis results in an anomaly in Indonesia compared to Japan and Australia, which clarifies the overlapping problem in ecotourism policy in Indonesia. It also visualized the shifting trends of research in some timeline intervals and notifies their relation to the emerging of ecotourism policy. This research also included the usefulness of the research results for future study and the recommendation for the ecotourism policy, especially for Indonesia.

Abstract

Fertilization and weed control are regularly conducted as the main silvicultural prescriptions in the eucalyptus plantation forest. However, the interaction effects of both treatments on eucalyptus performance are still not deeply understood, even though these treatments require high investment. This circumstance may potentially inhibit the managers to formulate more efficient maintenance strategy for increasing stand productivity. This study examined the interaction effects of fertilization and weed control on growth, biomass, and carbon storage in eucalyptus hybrid (E. pellita x E. brassiana). Results demonstrated that without both treatments, the average stand volume only reached 37.9 m3 ha -1 with the mean biomass and carbon storage approached 25.4 and 12.7 Mg ha -1, respectively. In contrast, the use of both treatments simultaneously improved the mean volume around 60.4 m3 ha -1 with the average biomass and carbon storage closed to 37.6 and 18.8 Mg ha -1. Furthermore, the development of eucalyptus hybrid using fertilization without weed control only gained the mean wood production approximately 58.7 m3 ha -1 while the practice of weed control without fertilization only resulted the average volume nearly 43.7 m3 ha -1. These facts indicated fertilization exhibited higher influence than weed control on the performance of eucalyptus hybrid.

Abstract

This article aims to describe the mangrove forest utilization for sustainable livelihood through a community-based ecotourism approach. This research conduct in Kao Village, North Halmahera District of Indonesia. This study was done in a qualitative method using a life-history approach. The data was collected through in-depth interviews, observation, and document study. The data were analyzed using a triangulation method to obtain credible information. These research findings show that cultural value, known as Higaro was able to mobilize the capability to access resources such as natural and social capital. In its development, assimilation and acculturation caused changes in livelihood structure. In addition, The mining sector's existence in the Kao community custom area had the potential to limit access to natural and social capital due to ecological loss. However, the mining sector could mobilize human and physical capital through Social Performance programs in the education sector and infrastructure development. The adverse effects of the mining sector to the environment had become such a stimulus for the Kao Village community to adopt an environmentally friendly development approach that had economic value and was able to improve the community welfare. Thus, the Kao Village community managed to maintain and utilize the mangrove forest using a community-based ecotourism approach to endurance livelihood sustainability. These results could be developed into recommendations for regional policymakers, especially in the rural areas, to mobilize the capability of local community access to capitals through the tourism sector to maintain livelihood sustainability.

Abstract

Communities in and around the forest always interact and use the resources to satisfy their daily needs for survival. Forest resources obtained by the community are used to satisfy family needs, and one is an additional family income. This study aimed at determining the contribution of Mutis Timau protected forest to community income. In order to knowing the income that the community earns from the forest, a survey was conducted in nine villages located in and around Mutis Timau protected forest that started from January to June 2018. Nine villages were purposively selected that Mutis Timau protected forest area is administratively under those villages whose communities directly interact with the protected forest. The technique of collecting data was a questionnaire with 353 respondents selected proportionally in each village. Also, observation and literature study were adopted. The data were descriptively analyzed. The results denote that Mutis Timau protected forest provide income to the community through non-timber forest products of IDR1,637,510,566 year-1 of the total income of IDR45,260,686,262 year-1. Community income earned from Mutis Timau protected forest is very low (3.62%) compared to the income gained from horticultural food crops (66.29%) and livestock (30.09%). The income is directly earned from the sale of non-timber forest products to the consumers without having product processes in particular for hunting wild animals, fungus, tubers, and honey. Honey delivers higher income besides other non-timber forest products, such as hunting wild animals, fungus, and tubers.

Abstract

The main issue of forest management policies in Indonesia is strengthening the role of Forest Management Unit (FMU) and community-based forest management. This study describes the performance of FMU and the priority needs for the institutional strengthening of FMU to promote community-based forest management in Central Sulawesi Province. The research applied a case study's descriptive method by exploring, classifying, and understanding the meaning of the problems encountered by the object examined. The study shows that the performance of the FMUs was not yet optimal in promoting community-based forest management. This problem attributed to the weak institutional capacity of FMU. Several aspects of the institution need improvements, including strengthening its capacity at the resort level, fulfilling the needs and capacity building of extension staff, as well as providing a legal mechanism for financial management to facilitate its business activities and cooperation. These priority needs were affected by government bureaucratic issues. It necessary the policy formulation governing the strengthening of community-based forest management in the FMU area that supports the independence goals of FMU.

Abstract

Restorasi ekosistem pada hutan produksi memungkinkan upaya restorasi dilaksanakan pada hutan produksi dan dipandang sebagai solusi potensial untuk memulihkan hutan produksi yang telah terdegradasi parah akibat pemanfaatan kayu yang tidak berkelanjutan. Terbitnya Peraturan Menteri Kehutanan No. SK 159/Menhut-II/2004 tentang restorasi ekosistem pada hutan produksi menandai perubahan paradigma pengelolaan hutan produksi di Indonesia dari sebelumnya yang berbasis pemanfaatan kayu menjadi berbasis ekosistem. Namun analisis isi kebijakan menemukan bahwa sebagian besar aturan restorasi ekosistem masih sangat berorientasi pada pemanfaatan kayu. Padahal, sebagian besar dari keenam belas unit manajemen restorasi ekosistem yang saat ini beroperasi di Indonesia, tidak bertujuan untuk memanfaatkan kayu. Kajian ini menemukan perlunya merevisi aturan perundangan yang berlaku saat ini untuk mengakomodasi beragam tujuan bisnis unit manajemen restorasi ekosistem termasuk tujuan utama restorasi ekosistem pada hutan produksi yang meliputi aspek ekologi, sosial, dan ekonomi. Kebijakan dan regulasi tersebut harus memberikan ruang inovasi yang luas bagi para pemegang ijin karena saat ini model restorasi ekosistem pada hutan produksi berskala besar belum ada. Ruang kebijakan untuk mendorong perbaikan kebijakan dan regulasi restorasi ekosistem pada hutan produksi telah tersedia yang didukung oleh koalisi aktor dalam Kelompok Kerja Restorasi Ekosistem.

Abstract

Aren (Arenga pinnata (Wurmb) Merr.) is a high ecological and economical value species of Indonesia. Aren grows spreading in Indonesia including at Meru Betiri National Park in the province of East Java, Indonesia. The community in Meru Betiri National Park uses aren fruit which is called kolang-kaling. Even though aren grows naturally in this area, the community has not maximized its utilization. This study aims to identify the actual and ideal conditions for aren conservation also to analyse the gap between them, and to formulate the conservation actions to realize a sustainable aren conservation in Meru Betiri National Park. The data wascollected by using vegetation analysis and in-depth interviews with all of the aren farmers. Aren regeneration in Meru Betiri National Park is categorized stable and seems to be decreased. The use of aren by the community is limited only from the fruit as kolang-kaling. There is a gap between current and ideal conditions for achieving aren sustainability. To achieve the ideal conditions, conservation actions are needed among aren farmers by utilizing agroforestry systems, increasing the value of aren, intensive coaching for aren farmers, and forming a group of aren farmer.

Abstract

This paper examines the identification of key indicators that could be used to measure the success of reclamation plants in post-exploration oil and gas mining areas. The main objective of this research was to find key indicators or variables for evaluating the level success of reclamation results in the post-mining of oil and gas area. In this study, 44 environmental variables of the physical, biological, soil, water and air indicators were analyzed from 70 field plots of 6 reclamation and 2 natural forest sites. The analysis methods included (1) cluster analysis using the Agglomerative Hierarchical Clustering method with the Ward's method, and (2) quadratic discriminant analysis. The results of the clustering analysis showed that there were some clusters due to variation of biomass, water, soil and air conditions. The three clusters developed based on water and/or air variables provided high cophenetic correlation (0.80) with low within-cluster (14.5%) and high between-cluster variations (85.5%). Based on the multicollinearity analysis, average vector difference test, variance matrix variance test, unidimensional test of each variable and quadratic discriminant function, this study found that there were 3 key indicators determining variations of the quality of the reclamation plantations within the study sites, namely, biological indicator of biomass volume (Bio_B); soil indicator of P content in the soil (Tnh_P), saturation base of soil (Tnh_Kb), Manganese (Mn) content in the soil (Tnh_Mn), Sulfur content in the soil (Tnh_S), percentage of ash in the soil (Tnh_Ab), percentage of clay in the soil (Tnh_Li), and water indicator of chloride content in the surface water (Air_Cl). The examination on four classes of the reclamation quality showed that the classes were successfully classified having excellent cross-validation error matrix with overall accuracy more than 90%.

Abstract

Damar mata kucing (Shorea javanica) is one of the non-timber forest products (NTFP)s that has been widely managed and utilized by local people around the Pesisir Barat Lampung Province. The majority of repong damar has been cut down, especially during the last 15 years. One of the reasons for decreasing community interest in managing repong dammar is the decreasing of dammar gum prices. This research aimed to analyze the market system of dammar cultivation in Pesisir Barat, Lampung Province. Descriptive analysis was used to determine the local community's knowledge, skill, and opinion in the trading channel. For further analysis, marketing margin and farmers' share were also used to analyze the price differentiation from the producer's level to the consumer's level. Based on the study results, there are three channels of the dammar gum market in Pesisir Barat Lampung. Most of the farmers (up to 85.71% of total) in Pekon Pahmungan use trading channels 1 and 2 to sell their harvested dammar. Meanwhile, based on the analysis of profit margin, it appears that farmers in channels 1 and 2 are trading actors that receive the lowest profit margin (IDR7,100 kg-1 and IDR8,100 kg-1) compared to trading channel 3 (IDR14,000 kg-1). Farmer's share obtained by dammar farmers in this study was 55.30% on channel 1, 52.20% on channel 2, and 76.80% on channel 3. Livelihood, limitation on capital, lack of information and networking, knowledge and abilities to tree management and harvested dammar, knowledge of another use of dammar gum, and the ability to use technology directly affecting farmers' position in the dammar gum trading system.
