Abstract

Some communities and governments in Indonesia have taken the initiative to develop waqf forests to solve forest conservation problems. However, research on waqf forest development is still rarely studied. This study aims to improve the strategy of waqf forest development in Indonesia. SWOT method is used to identify the strengths, weaknesses, opportunities, and threats and the possible development strategies of the Bogor Waqf Forest as a manager of Waqf Forest. The ANP method prioritizes these four aspects and the best strategy in developing the waqf forest. An aggressive strategy needs to be carried out by optimizing the existing legal organization and the well-educated human resources to inform the public about the waqf concept in Islam and its application in the waqf forest. Thus, the vast potential of cash waqf and waqif can be obtained. This paper is one of the pioneering articles that discuss waqf forest development strategies, especially in Indonesia. From this research, we recommend the Bogor Waqf Forest to resolve the legal aspects as an official waqf manager, and the government and Indonesian Ulema Council to issue regulation and fatwa regarding waqf forest.

Abstract

Binuang bini (Octomeles sumatrana Miq) is a fast-growing tree with numerous economic benefits, such as the provision of wood for carpentry purposes, building boards, water management, and absorption of carbon dioxide (CO2). Therefore, this tree species has great potential and needs to be included in Reducing Emission from Deforestation and Forest Degradation (REDD)+'s mitigation program to tackle climate change. In its development, REDD+ has made it possible to carry out carbon trading in the world. Therefore, countries capable of performing protective functions and carry out reforestation, afforestation, and restoration, have the opportunity to be involved in world carbon trading. This study aims to determine the moisture content and carbon absorption rate of Binuang bini trees as a first step to regulate the allometric equation using destructive and laboratory analysis. The results show that the water content in the roots, leaves, as well as the base, middle, and tip of the stem were: 73.69%, 68.39%, 65.59%, 61.22%, and 66.26%, respectively. Furthermore, the sample test results indicate a very close relationship between carbon concentration and absorbance in the O. sumatrana tree with a simple linear regression equation: Y = 0.002X + 0.0593 with R2 = 0.9896. Therefore, this regression equation can be used to calculate the carbon concentration sample for the O. sumatrana tree fraction. The carbon content in 3 tree samples with a breast height diameter of 9.24 cm, 10.08 cm, and 11.68 cm was 2,585 kg. 2,913 kg, and 4,654 kg, respectively. In addition, the carbon sequestration for each tree diameter per year is 1.581 kg year-1, 1,782 kg year-1and 2,847 kg year-1, respectively.

Abstract

Climate change has forced human being to adapt in fulfilling their energy needs sustainably. In Indonesia, forestry activities has been considered as an emission rather than carbon sink. This study aims to analyze the inputs, outputs, and potential environmental impacts of wood pellet production in a forest company using life cycle assessment (LCA). The wood pellet is made from Eucalyptus pellita plantation. Analysis was made for 1 planting cycle or 6 years, and allometric equations were used to estimate the ability of industrial timber plantation forest to absorb CO2. Production of wood pellet starting from plantation requires inputs as follows: diesel fuel, electricity, NPK and other fertilizers, pesticides, and electrical energy. Those inputs produced emissions, of which the largest was N2O of 551.2927 kg, followed by NH3 of 7.5275 kg generated from NPK fertilizer. Another was PO43- amounted at 0.1792–0.2229 kg from liquid fertilizers and pesticides. Potential acidification came from 13.3675 kg SO2 eq, and eutrophication of 0.4021 kg PO43- eq. The greenhouse gas (GHG) emission was 678.0270 kg CO2 eq from the plantation activities, especially from diesel-based energy consumption, while wood pellet mills only released 0.1053 kg CO2 eq of GHG emissions. Thus, total emissions from 6 years' time of wood pellet production are much lower compared to the average CO2 absorbed by the plantation forest, of which annually is 36.34–67.69 ton ha-1year-1.

Abstract

The abandoned land and indicated abandoned land are considered critical land or land that is less productive. Those lands covered about 13,000 ha of Bogor Regency area, with the critical land area of around ​​93,467.51 ha (32%). To reduce the area of critical land and increase land productivity in Bogor can be done by optimizing the abandoned land for private forest use. This study aimed to analyze the potential and opportunities for private forest use in abandoned land. The method used was an investigative approach with quantitative and qualitative descriptive analysis. This study showed that in terms of land characteristics and biophysical conditions, the abandoned land could be developed for private forest business, especially to cultivate forest business, such as sengon (Albizia chinensis), kayu afrika (Maesopsis eminii), jabon (Neolamarckia cadamba), mahoni (Swietenia mahagoni), and kayu manis (Cinnamomum verum). The majority of respondents (65%) were willing to do partnerships in private forests. However, several factors are needed to support this business, i.e., regulations in the form of incentives and disincentives from local governments, investors, facilitators, and market access.

Abstract

The allocation of land use in Indonesia is very inefficient, while the distribution of tenure is unequal. Half of the land for cultivation is held by forestry, and the other half is used by various other sectors. Most Indonesian farmers are small- scale farmers who do not meet economies of scale. Agrarian reforms aimed at overcoming inefficiency in land use, eliminating inequality in land tenure, and promoting rural areas’ prosperity need to involve land for cultivation allocated for forestry. This paper is written based on the author’s experience of interacting with various parties related to land issues, forest areas and agrarian reform through various forums, such as official meetings, focus group discussions, seminars, workshops, symposiums, one-on-one discussions (interviews), and interactions through social media. Agrarian reform, which has been launched since 1960, has not been able to be realized until today. The fight seems to involve two large groups, namely environmentalists and developmentalists, but this kind of grouping is likely to be misleading. Environmental issues may only be used as an instrument to obtain economic benefits as well, not for the environment itself.

Abstract

Analysis of the relationship between inequality, agrarian reform, and corruption as well as public administration reform has not been discussed, both in terms of the formation and implementation of agrarian reform in Indonesia. This article aims to explore the concept and implementation of agrarian reform, as well as the influence of governance conditions in the management of natural resources in the implementation of agrarian reform. With the characteristics of agrarian issues in Indonesia, land administration and those related to the implementation of redistribution of benefits from the use of natural resources need to be strengthened with appropriate concepts or theories, including public information disclosure as a fulfillment of substantive and deliberative implementation of democracy. In addition, by referring to experiences in other countries, agrarian reform needs to be carried out by reducing the level of clientelism and implemented through a number of corruption prevention and prosecution programs, especially in the fields of land and other natural resources.

Abstract

The response of tropical trees to the change of light intensity has been reported to be varied among different species. Some reports argued that the growth was increasing parallel to the increasing of light intensity, but other reports mentioned that the sensitivity to the light intensity was depending on the species. Another environmental factor that has been scientifically proven to affect tree growth is humidity. While humidity itself also directly affected by the light intensity in the forest ecosystems. Therefore, it is possible that the growth pattern of trees under different light intensities is also affected by air humidity under the canopy. This research aimed to study the growth response of a light-demanding Alstonia scholaris and a shade-tolerant Eusideroxylon zwageri to the different levels of air humidity and light intensity. The experiment was conducted in Jambi, Indonesia from April to November 2019. The experiment was carried out using split plot design with factorial treatments. The main plot was the air humidity with three levels and the sub plots was light intensity with five levels. Four replicates were applied. In general, the A. scholaris tends to be more sensitive to the humidity and light intensity compared to E. zwageri. In particular, A. scholaris tends to be more sensitive to the light intensity while, E, zwageri is more sensitive to the humidity. However, there is also strong indication that the effects of light intensity to the growth, especially for A. scholaris, was affected by the humidity level.

Abstract

Forest and land fires occur almost every year in South Sumatera Province, including at Ogan Komering Ilir (OKI) Regency, mainly due to uncontrolled burning activities. This region has the largest peatland responsible for the adverse haze impacts. The advent of the coronavirus (COVID-19) pandemic in early 2020 has triggered massive consequences across the global communities, including Indonesia. Therefore, large-scale regulations on social restrictions were enacted. The purpose of this study is to analyze the variations in hotspots as forest and land fire indicators before and during the COVID-19 pandemic in OKI as well as to determine the rainfall effects. Daily Terra/Aqua MODIS satellite feeds and rainfall data between January 2018 and December 2020 served as the research materials. Subsequently, the paired t-test and correlation assessment were used to examine the hotspot variations in both datasets, respectively. The results showed significant statistical differences before and during the pandemic. Consequently, social restrictions were assumed to instigate the decline in burning activities. Furthermore, the rainfall demonstrated a vulnerable correlation to the hotspots, indicating that human factor was more pronounced as a fire trigger.

Abstract

A series of soft skill training in four national parks of Sumatra Island were conducted by PILI Green Network NGO, DG of Natural Resources and Essential Ecosystem Conservation of the MoEF, and Sumatran Tiger Project-UNDP for 12 months in 2019. The training aims at improving soft skill capacity of the national park staff on conflict management and collaborative actions with the communities in the buffer zone. This paper aims 1) to evaluate the soft skill training programme achievement by employing Kirkpatrick’s evaluation model; 2) to analyse factors of Training Program participants that influence on the individual soft skill enhancement by using multiple linear regression analysis. The results show that soft skill training was effective to increase the knowledge and skill of the participating staff, especially in participatory approaches, conflict management, and the development of a collaborative business model. Three factors, including work experience, the suitability of background education and similar training experience, have significant influences on the individual soft skill enhancement. Training design, which was bottom-up and participatory based on the needs of the resorts as a spearheading of national park management, contributes to the success of the training implementation. The training has created a ‘common room’ for the participating staff and the communities in terms of opening communication and development of collaborative action plans at each national park.
