Abstract

Soil fertility in land after nickel mining has a change in soil texture that changes both the profile color and the soil irregularity. Damage to the physical properties of the soil affects the soil nutrients needed by plants. Several physical and chemical properties of soil are influenced by texture including soil plasticity, soil permeability, ease of cultivation, lack of soil fertility and productivity. Stable soil fertility can support plant growth. Damage to the physical properties of the soil due to the loss of the soil interest (solum) by the ongoing washing of the soil. This results in the loss of some cations in soil colloids, resulting in low acidity (pH) of the soil becoming acidic. Cation Exchange Capacity (CEC) as the amount of charge of cations absorbed by soil colloids at a certain pH. Another factor in the decline in CEC is the decreasing number of cation nutrients that can be exchanged. The relationship with reclaimed and revegetated land is influenced by climatic factors with rainfall intensity. Soil fertility on revegetated land with CEC value and C-organic content was very low. Such soil fertility conditions are found in the revegetated zone with large leaf acacia (A. mangium) vegetation; sengon (P. falcataria); ketapang (T. catappa) and waru (H. tiliaceus). Soils that have low soil nutrient content are characterized by low organic matter content, very low available P content, and low cation exchange capacity.

Abstract

Arbuscular mycorrhizal fungi (AMF) and biodegradable pots are environmentally friendly and enhance plant growth in adverse soil conditions. These studies explored AMF interactions and biodegradable pots in physiology, growth, and the uptake of nutrients in Samanea saman seedlings. The present research interactive effects of biodegradable pots with different compositions and raw material sizes with and without AMF inoculation on S. saman grown in silica post-mining soil media. Results indicated AMF inoculations significantly improved leaf chlorophyll content, photosynthetic rate, heights, diameters, biomass, as well as nutrient absorption of S. saman as compared with non-inoculated plants in biodegradable pots. AMF and biodegradable pots composed of 15% used newspaper, 70% compost, 5% cocopeat, and 10% rock phosphate showed the best results and increased the leaf chlorophyll content, photosynthesis rate, height, diameter, and total biomass of the plants by 161.1%, 208.7%, 263.6%, 118.1%, and 269.9%, respectively, compared to biodegradable pots composed only of used newspaper. Additionally, uptake of the nutrients nitrogen, phosphate, potassium, and magnesium increased by 365%, 800%, 369%, and 250%, respectively. By the fourteenth week after transplanting, the C/N ratio of the organic pot decreased significantly. Thus, AMF and biodegradable pots containing compost and rock phosphate interact positively and enhance the growth of S. saman under adverse soil conditions. These findings suggest that biodegradable pots containing compost and rock phosphate show potential as more environmentally friendly replacements for plastic bags (polybags) as growth medium containers for seedling production.

Abstract

ABSTRACT The Aek Nauli Environment and Forestry Research and Development Center (BP2LHK Aek Nauli) has a relatively high budget absorption rate, averaging 96.96% from 2012 to 2016. However, this high budget absorption rate does not necessarily imply that the performance and budget management at BP2LHK Aek Nauli are perfect. Issues such as expenditure accumulation at the end of the year and discrepancies between planned and actual budget absorption on a monthly basis still persist. This study aims to recommend performance improvement strategies for the Aek Nauli Environmental and Forestry Research and Development Center using the SWOT method. The research results identified 10 strategies to enhance performance at BP2LHK Aek Nauli, including (1) Improving commitment to adhere to previously created documents, (2) Enhancing communication for rapid information dissemination related to the latest regulations, (3) Increasing routine evaluation and internal supervision to enhance compliance with regulations, (4) Allocating Non-Tax Revenue Budget (PNBP) to programs linked to seasonal variations, (5) Creating alternative budget arrangements, (6) Improving the quality of human resources to understand performance measurement processes, (7) Enhancing communication among employees regarding service, performance, and performance measurement, (8) Formulating activities aligned with the vision and mission, resulting in excellent public service, (9) Improving cooperation for utilizing research results with local stakeholders, and (10) Enhancing the dissemination of research findings. Keywords: BP2LHK, Budget Absorption, Strategy, SWOT

Abstract

Padang sapu-sapu soil is similar with post-tin mining soil in its white sand texture and poor nutrient. One factor causes the disturbed land in Bangka Belitung islands is tin mining activity. One method to rehabilitate marginal soil is by utilizing the potential nonsymbiotic N2-fixing bacteria, which are able to fertilize the soil and is able to provide macro nutrient. This study aims to measure the abundance and potency of non-symbiotic N2-fixing bacteria in padang sapu-sapu, Pejem Village, Bangka. The site selection is determined by purposive sampling method and interviews and the samples were collected randomly. Isolation used selective media Ashby'`s Monitol Agar and Azospirillum media. Morphological characterization was conducted on isolates and a series selective test was carried out, i.e. hipersentivity test, hemolysis test, IAA phytohormone test and nitrogenase test. The study of the abundance population of non-symbiotic N2-fixing bacteria of two different locations showed that the total bacterial population in padang sapusapu is very small compared to its lowland forest. Isolate Azotobacter sp. TH105(a) from the lowland forests is potential as natural fertilizer.

Abstract

The 0.6% contribution of the forestry sector to GDP is considered very low despite 64.1% of Indonesia's land area being allocated as forests. Most of the 64.8% production forest allocated is not yet optimized for strengthening national food security, in which Indonesia is ranked 65th in the world. Therefore, an innovative forest management system is needed to synergize timber and non-timber production. This paper presents a multi-business forestry (Mb-F) implementation strategy analyzed through a dynamic system-based multi-criterion decision-making tool named Super Model Mb-F (SM Mb-F). SM Mb-F is built based on a causal loop diagram (CLD), which describes the dynamic relationship between land typology suitability and decisions related to the type of business, commodities, land use area, workload, and financing for many variables relating to 5M business principles and sustainability. Results showed that CLD formulated in 280 sub-models in a total of 4,764 decision variables with an error deviation of 6.4%. The SM Mb-F simulation on two sample concession units produces a projected increase in wood supply, employment, and state revenue, plus the provision of new functions such as food, NTFP, and environmental services. These benefits are obtained by business feasibility. Assuming that gradually until 2030, the Mb-F can be implemented in 32% of Indonesia's production forests, then by 2045, it is projected that there will be an increase in wood production by 296.8%, state revenue by 654.3%, and labor absorption by 985.7%, as well as adding food production up to 19.36 M tons. This is because the land use efficiency of the current operation of forest concessions following the Annual Allowable Cut (AAC) under the selective cutting and replanting system in Indonesia (TPTI) is only about 3% of the total area of forest concession. Assuming the cutting cycle is 35 years, timber could be extracted in 1/35 of the total forest concession area. Implementing Mb-F will significantly improve the land use efficiency from about 3% to 90%.  The Mb-F will also restrain the rate of decline in carbon stocks, which is deeper if governance is still under the BAU scenario. This research suggests further global research, emphasizing the importance of innovative models for sustainable forestry governance and food security worldwide.

Abstract

From 2015 to 2021, the Indonesian government collaborated with the Japanese government for the Forest Preservation Program in the Republic of Indonesia to restore the Matalawa NP ecosystem in degraded areas. This program has been running for five years, so it should provide changes to both social and forest conditions. This research aims to explain community perceptions, and social and forest conditions after the program. The research method includes interviews with locals and interpretation of satellite images. Analysis of interview data uses descriptive-quantitative methods, and interpretation of satellite images uses the NDVI. The research results regarding community perceptions of the program showed that their perceptions regarding the function and benefits of the program are classified as very good. Social changes occurred in the management of agricultural land, the intensity of coordination between the community and the Matalawa National Park, increasing public awareness to recognize the Matalawa National Park area, and attitudes toward mutual deliberation and cooperation. Image interpretation showed that vegetation in degraded areas is still dominated by low vegetation density. Medium and high vegetation density increased after the program. The ecosystem restoration program in Matalawa, NP, has positive implications for the community's social and environmental conditions. This impact can make the ecosystem restoration program a policy in managing Matalawa National Park. Keywords: Restoration, Community, Matalawa NP

Abstract

Open-pit clay mining has the potential to disrupt the environmental ecosystem. Reclamation is carried out to aid in the recovery of areas disturbed by mining processes. This study aims to determine the effect of applying manure and eco-enzymes on the growth of eucalyptus in post-mining clay land and to identify the optimal combination dosage of manure and eco-enzymes to enhance eucalyptus growth in these reclaimed areas. This study used Randomized Block Design with two factors: manure (0, 1, 1,5 kg) and eco-enzymes (0, 100, 150 ml). The results show that the interaction between manure and eco-enzymes had a significant effect on plant height and canopy thickness, although both treatments did not significantly affect plant diameter and canopy diameter. The best dosage for improving eucalyptus growth in post-mining clay land was 150 ml of eco-enzymes. Keywords: clay mining, eco-enzymes, eucalyptus, manure, reclamation

Abstract

Acid mine drainage (AMD) is formed because rocks containing sulfide minerals, such as pyrite (FeS?), are exposed to oxygen and water. AMD treatment is generally carried out with lime, but this method is relatively expensive and unsustainable. Fly ash-bottom ash (FABA), a type of coal combustion waste can potentially replace lime in treating acid mine drainage (AMD). This study aimed to elucidate the potential use of FABA to neutralize pH of AMD. The method used was a floating FABA system using styrofoam with three treatments: floating FABA with dimensions (cm length x cm width x cm height) of 33x33x8 (F1 30), floating FABA of 28x28x8 (F2 25), and floating FABA of 23x23x8 (F3 20). The floating FABA consisted of 85% FABA and 15% cement, with a 120 L AMD. The results showed that the F1 30 treatment reached a pH of 6.06 from an initial pH of 4.2 within 3 days. The floating FABA application also reduced the concentration of heavy metals (Fe and Mn) and total suspended solids (TSS) in the F2 25 treatment. Micro XRF analysis indicated a high element distribution in the floating treatment zone, supporting the neutralization mechanism of precipitation and adsorption. The results of the statistical analysis showed no significant difference between treatments, indicating that all treatments were effective and could be considered based on cost efficiency and retention time. Overall, the floating FABA application increased pH and progressively reduced heavy metal content, supporting its use as an efficient and sustainable AMD neutralization solution.

Abstract

Open-pit coal mining activities have an impact on environmental changes, one of which is the emergence of acid mine drainage. Acid mine drainage (AMD) arises from sulfide minerals that react with oxygen and water. Coal utilized in electric steam power plants as fuel to produce electrical energy results in combustion residue known as fly ash and bottom ash (FABA). FABA has alkaline properties and has the potential to be combined with plant species that are resistant to acid mine drainage (AMD). This study aimed to explore the potential use of FABA as a growing medium for eucalyptus (Melaleuca cajuputi) to neutralize the pH of acid mine drainage (AMD) in artificial wetlands. FABA block medium was made by mixing FABA, cow manure, and cement as an adhesive and incorporating holes as planting media. The results of this study showed that the application of FABA and cow manure increased the pH of AMD from 3.27 to 6.27 in 24 hours. FABA medium blocks could adsorb heavy metals in AMD, such as Fe in the K1-P1 treatment, from a value of 0.15 mg/L to 0.08 mg/L, and heavy metal Mn in the K3-P3 treatment, from a value of 4.1 mg/L to 0.2 mg/L. In addition, medium blocks K2 (50% FABA + 30% cow manure + 20% cement) and K3 (30% FABA + 50% cow manure + 20% cement) had a good effect on the growth of M. cajuputi seedlings in the K3-P1 treatment with an average height of 17.67 cm and a stem diameter of 9.2 mm for 8 weeks.
