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.

Abstract

Forest fire was a persistent concern management in conservation areas of Mount Ciremai National Park (MCNP) and Kuningan Botanical Garden (KBG). Many of the forest fire was sparked by anthropogenic ignitions like careless fire use for extracting forest honey. This study aims to map multi stakeholder roles on fire management in conservation areas. Twenty-seven actors were interviewed to learn who are the fire actors and network. These multi stakeholders included government officials, local businessmen, non-governmental organizations and community members. Study site and data collection were carried out in seven villages around conservation areas from July to September 2019. The relationships between the actors were analyzed with the software Node XL Basic and Gephi 9.0.2 using the Social Network Analysis. Our results identify close relationships and strong connections to all actors of more than half (63.2%) but social or personal approach between all actors were still required. Head of MCNP, Head of KBG and Head of AKAR (Aktivitas Anak Rimba) acted as the important actors. To prevent the area from further fire occurrences, management authorities should establish mutual confidence and make other actors believe that heads of conservation areas are a solid team to prevent conservation areas from burning.

Abstract

Safety perception is the most important part of people's choice in determining tourist sites. Standing trees that are prone to falling are very dangerous for both visitors and employees. Standing tree with decay wood inside is often the cause of tree failure. Therefore, there is a need for research examining the risk of collection and non-collection trees in Bali Botanical Garden. Tree risk checks were carried out using the Tree Risk Assessment method from the International Society of Arboriculture (ISA), which has been modified. The result of this research gives valuable information for the manager to determine tree handling to minimize tree risk.

Abstract

Villages around Kerinci Seblat National Park (Taman Nasional Kerinci Seblat, TNKS) have experienced population pressure. This condition which if not addressed immediately will encourage the community around the TNKS to enter and encroach the forest to meet their household needs. This is getting worse along with the finding that the community around TNKS also does not have many alternative sources of income. For this reason, designing strategies for optimizing household economic to lessen population pressures are noteworthy. Focus group discussion (FGD) and analysis hierarchy process (AHP) was applied to design and to determine development strategy for household economic empowerment and twenty-five key informants including fifteen farmer households were interviewed. The AHP results conclude that the production aspect is the most important that needs to be given priority in the development of plantation production. This conclusion is based on its highest relative priorities (weights), i.e., 0.298. Of the three programs identified and using weight result of AHP, community seed assistance is the most important program in the development of plantation production (weight of 0.494). The seed assistance program is the most important compared to providing soft loans (weight of 0.29) and expanding to production inputs accessibility (weight of 0.216). Meanwhile, human resource development aspects are the most attractive strategy for food crop production development, especially rice, with a weight of 0.325. Aspects of human resource development are more focused on improving farmer knowledge in cultivation than marketing and post-harvest handling aspects. Optimization of pekarangan resources is directed to the development of the chicken farm (weight = 0.274) focused on improving the production aspect (weight = 0.328). Among three priority programs, day-old chicken assistance (weight = 0.512) is more needed than access to soft loans (weight = 0.242) and feed programs (weight = 0.246).

Abstract

Limestone mining has the potential into environmental damage that involve modify an ecosystem. The attempt that contrived to reduce the disturbances are rehabilitation. This research was conducted to examine the growth response of Leucaena leucocephala inoculated with AMF and soil ameliorant in a limestone post-mining soil. The design used was a split-plot design in a completely randomized design with 3 factors. The first factor was AMF inoculum (Daemonorops draco AMF and MycoSilvi), the second factor was organic fertilizer of compost, and the third factor was inorganic fertilizer. The variables used in this study expressed by height, diameter, biomass, root colonization, and nutrient absorption of the plant. The analysis showed that the combination of MycoSilvi and compost 7.5% gave best result of height, diameter, and biomass, with significantly increased by 962.67%, 899.41% and 1440.67% to control plant. It also gave best result of nutrient uptake N, P, and K, with significantly increased up to 17.64 g plant-1, 2.42 g plant-1, and 18.05 g plant-1. In general, AMF showed a good percentage of root colonization with an average 36.67-86.67%. Further research is needed to determine the response to the growth of seedlings planted in the field.

Abstract

The Nantu Forest in Gorontalo Province, Sulawesi, Indonesia holds one of the few remaining pristine habitats in the island. The reserve is surrounded by human habituation which provide opportunity to study the impact of forest lost on biodversity. In addition, data on Nantu mostly focused on big mammals, as there is no previous herpetofauna survey at the area. Sampling of amphibian and reptile was conducted in June 2013 and in May–June 2014 using Visual Encounter Survey method, glue traps and transect sampling in seven different sites at the eastern part of Nantu. We categorized four habitat types based on human disturbances: high disturbed habitat (HDH), moderate disturbed habitat (MDH), low disturbed habitat (LDH) and pristine habitat (PH). A total of 680 individual amphibians (4 families; 17 species) and 119 individual reptiles (9 families; 29 species) were recorded. Species richness and species composition for amphibians and reptiles differs according to the level of human disturbances. Low level disturbances habitat demonstrated the highest diversity of amphibians and reptiles, whereas as expected, high distubed habitat showed the lowest diversity. Anthropogenic pressures in forest will decrease species richness of amphibian and reptiles. Although most amphibian and reptiles will be able to persist in low disturbances habitat, forest-dependent species will be lost when pristine forests are disturbed.

Abstract

Local wisdom has been coexisting with the state system in several places in Indonesia. The Mountain Mutis Nature Reserve in East Nusa Tenggara province is the strict nature reserves, but a customary land tenure system, called suf, exists so far in the nature reserve. The objectives of this study are (1) to organize the historical territorialization process, (2) to clarify the customary land tenure system and activities for livelihoods by local people, and (3) to discuss the challenges of its land tenure system to manage forests sustainably as well as policy methods to harmonize legal pluralism in Mutis Area. Field observation and in-depth interviews with key informants were employed for data collection, and the collected data were analyzed by a qualitative descriptive method. The findings showed the traditional reward and punishment systems regarding extracting non-timber forest products, grazing livestock, and preventing forest fires were working well for sustainable forest management. However, increased pressure on forests due to future population growth appears to have an impact on the traditional system. It also showed the government officers and local people started some discussions to recognize the suf in the formal legal order. However, there were institutional problems to introduce current state systems. Therefore, it is required to flexibly operate or revise the state laws according to the actual situation to harmonize society between state and people.
