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.

Abstract

Permasalahan pada lahan pasang surut dapat diatasi dengan penerapan sistem teknologi pertanian spesifik lokasi seperti penerapan sistem budidaya jenuh air dan pemanfaatan mikroorganisme lokal seperti jamur mikoriza arbuskular (FMA) sehingga lahan pasang surut marginal dapat menjadi lahan produktif dan tanaman tebu dapat berproduksi secara optimal. Penelitian ini bertujuan untuk menganalisis pengaruh penerapan beberapa sumber inokulan FMA lokal dan periode pasang surut dan jenuh air terhadap karakteristik agronomi tebu. Percobaan menggunakan Rancangan Blok Lengkap Teracak dengan dua faktor. Faktor pertama adalah inokulasi FMA yang terdiri dari tanpa inokulasi, inokulan jagung, inokulan kedelai, inokulan tebu, dan inokulan tanaman gabungan (tebu-kedelai). Faktor kedua adalah lamanya kejenuhan yaitu 0, 2 dan 4 bulan setelah tanam, sehingga terdapat 15 perlakuan dengan tiga kali ulangan. Hasil penelitian menunjukkan bahwa interaksi antara sumber inokulan dan lama kejenuhan tidak berpengaruh nyata terhadap semua parameter pertumbuhan dan fisiologis. Aplikasi berbagai sumber inokulan berpengaruh positif terhadap pertumbuhan dan fisiologi tanaman tebu, khususnya sumber inokulan jagung. Baik pada umur 2 maupun 4 bulan setelah tanam, kondisi jenuh tanah menunjukkan pertumbuhan dan respons fisiologis terbaik dibandingkan dengan sistem budidaya konvensional (tanpa kondisi jenuh).

Abstract

Silvopasture system improvement in managing post-mining land resources has been done by searching for a quality grass. One of the selected grass species is signal grass (Brachiaria decumbens Stapf.). This research aimed to prepare signal grass through the inoculation of AMF Claroideoglomus etunicatum, as an effort to enrich its growth before being applied to post-mining soil. Research stages included the AMF inoculation on signal grass through spore culture and then transferred the colonized grass to the pot using sterile zeolite as a growth medium. The treatment on the first stage was without and with AMF inoculation (dose of 20 spores) on signal grass which was repeated for 12 times. Incubation in a spore culture was 4 weeks while incubation in a pot containing sterile zeolite medium was 8 weeks. Research data were analyzed using the Shapiro-Wilk’s normality test, Independent Sample T-test, and Pearson’s correlation test. Observation results showed that the inoculation of C. etunicatum on signal grass was significantly impact on the increase of plant height, stem diameter, number of leaves, number of tillers, shoot and root fresh weight, and shoot dry weight (p <0.05). Microscopic observation showed that there was AMF colonization on treated signal grass roots in the amount of 55 ± 0.06 % with number of spores was 252 ± 9.82 per 10 g zeolites, while AMF infection was not found in uninoculated signal grass. It is expected that by providing signal grass inoculated with AMF C. etunicatum would support its growth in post-mining land for Silvopasture system.

Abstract

The response of composting microbes to fly ash can show an increase or decrease in population depending on the type and concentration of fly ash used. This study aims to identify the effect of fly ash addition on the composting of citronella (Cymbopogon nardus (L.) Rendl.) leaf waste, specifically in relation to changes in the C/N ratio and the number of composting microbes, and the identification of fungal species that developed during the process. The composting treatments included citronella leaf waste without alkali (K), also with the addition of alkali in the form of 2% dolomite (D), fly ash of 2% (FA1), 5% (FA2), 10% (FA3) and 15% (FA4). The analysis used in this study was a quantitative descriptive analysis related to the analysis of C-organic and total N, as well as composting microbes. Quantitative descriptive analysis was employed to assess C-organic content, total nitrogen, and microbial populations. The results demonstrated that the incorporation of fly ash influenced both the C/N ratio and microbial abundance. The addition of 10% fly ash proved to be the most effective treatment, increasing nitrogen content and reducing the C/N ratio to 26, while supporting bacterial growth up to 3.0 × 10¹¹ CFU/g. Fungal identification revealed the presence of Rhizopus sp., Trichoderma sp., and Aspergillus sp., which contribute to the degradation of organic matter in citronella leaf waste.

Abstract

Surface mining, including tin mining, is the most common mining practice in Indonesia. The existence of mining ore or minerals close to the surface soil is the reason for carrying out this mining method. The process of mining surface resulted in the change of land landscape, which may cause soil erosion and even flood. It has caused various ecological and environmental problems, including soil degradation. This study describes soil physio-chemical properties impacted by surface tin mining in Bangka, Indonesia. Soils were collected from three different land use in natural forest, agroforestry, and post tin mining area in Bangka Regency, Province of Bangka Belitung Island. Five-spot soils were sampled from each site. Each site had three replication of the sampling area. The plot size for each site is about 200-500 m2. Soil texture, pH, total N, available P, exchangeable K, organic carbon, C/N ratio, CEC, Al3+, and H+ were analyzed. The results showed that mining decreased organic carbon, total N, available P, exchangeable K, and CEC. Mining changed the soil texture to be dominated by quartz sand. These results indicate that mining significantly deleterious soil fertility, therefore, potential as a limiting factor for plant growth, which could be a hamper for restoration efforts of post tin mining areas.
