Abstract

Reclamation of post-nickel mining soil requires a long process and renewable innovations to improve soil properties. One of the alternative technologies for post-mining soil reclamation is utilizing oil palm empty fruit bunches (OEFB) as biochar and applying calcite (CaCO3). The objective of this research was to determine the effect of OEFB and the application of CaCO3 on the properties of post- nickel mining soil and the growth of Mucuna sp. This research was a pot experiment using a factorial randomized block design method. Treatments tested were combinations of three OEFB biochar (B) levels, i.e., B1 = 2.5%, B2 = 5%, and B3 = 7.5% of soil weight, and three calcite (K) dosages, i.e., K1 = 1.5, K2 = 3, K3 = 4.5 t ha-1. The soil parameters measured included soil pH, available P, organic C, cation exchange capacity, and exchangeable Al, Ca, Mg, K, and Na. The parameters of Mucuna sp. measured were plant height and plant dry weight. The results showed that applying biochar and calcite to post nickel mining soil significantly increased soil pH, available P, organic C, cation exchange capacity, growth of Mucuna sp. and decreased exchangeable Al content. Treatment of biochar 7.5% by weight of soil and 4.5 t calcite ha-1 gave the best effect on improving soil fertility and growth of Mucuna sp. compared to other treatments.

Abstract

Slope stability is the primary factor in designing a stable slope. The strength of the disposal slope relies on the characteristic of the dump materials. The rock shear strength denotes rock ability to withstand the burden, both constant and dynamic load. The weakest material used as a reference in designing the disposal slope is siltstone in Pulaubalang formation (location-04). The safety value in Location 04 and 02 tend to drop quickly as the inclination increase, while the safety in location 01 and 03 tend to fall slowly. This indicates that rocks with a lower plasticity index tend to be stronger in steeper slope conditions. The slope geometry was designed to be 10, 15, 20, and 25 meters high with a slope angle of 10o, 15o, 20o, 25o, 30o, 35o, 40o, 45o, 50o, 55o, and 60o. The slope geometry is considered stable and safe. However, this study suggests that the most effective slope design is the slope with 25 meters high, overall slope of 25,3o; the single slope of 35o; berm width 4,66 meters, bench height of 5 meters, with the safety factor value of 4.30 (SF= 4.30).

Abstract

 The combination of water and land ecosystems as found in riparian areas offers valuable ecosystem resources, in dryland areas. The aim of this paper was to draw a management plan for the utilisation, and protection of the riparian forests or woodlands along the Black Volta River in Nandom Municipality. An exploratory research design was used together with quantitative and qualitative approaches. A survey of 75 respondents from 10 communities, 10 key informant interviews, and five focus group discussions in five communities were used to collect primary data. Satellite images for 2001 and 2014 were sourced from USGS site. The results revealed that riparian forest loss was 6.4% over 13 years. There was an increase in bare area by 10.6% over the same period. The study identified 49 plant resources, 14 wildlife resources, and 25 halieutic resources. A five-year management plan was developed with community participation; the implementation of which would engender sustainability of the riparian ecosystem.

Abstract

Coal mining by the open-pit mining method creates the formation of a pit lake. The ex-mining site, over time, was gradually filled with contaminated water and must be returned to the water quality standard of compliance level. With proper treatment, the pit lakes have the potential for several benefits and subsequent uses. This study aimed to analyze the existing condition of the Paringin Pit Lake at South Kalimantan by identifying the quality of the water flow, and it is compliance with the parameter threshold values. The results showed that the pit lake water management had been carried out supported by good management of the catchment area and was indicated the stable category by geology technical study. The success of its revegetation processed in the area was shown by an erosion study in which the result was a very low-level category. No less important is the management of runoff water both in the quantity of water balance control and consistent water quality treatment to meet the quality standard values that have been set. The Paringin Pit Lake water management strategy is a form of activity that demonstrates compliance with good and responsible mining principles to support sustainable development that can serve as a good reference and example for other mining activities in terms of mine closure preparation.

Abstract

Mercury composite and cyanidation are gold mining methods that are frequently used. The mercury composite method produces tailings containing heavy metals that can harm living organisms. Utilisation of tailings for the development of forage may be enhanced through arbuscular mycorrhizal fungi (AMF) inoculation to increase plant resistance, absorption of macro and micronutrients, and reduce levels of metal contaminants in the tailings. This study aimed to investigate the effect of arbuscular mycorrhizal fungi on nutrients and heavy metals uptake by Pennisetum purpureum cv Mott in phytoremediation of gold mine tailings. Treatments consisted of four levels of AMF inoculation (0, 5, 10 and 15 g pot-1) were arranged in a completely randomised design with five replications. Each pot contained 3 kg of tailings. The results showed that the best crude protein, crude fiber, crude fat, Ca, and P contents in the plant shoots was obtained by providing AMF inoculation of 15 g pot-1. However, the treatment had no significant effect on dry weight, dry matter, and nitrogen-free extract. AMF significantly increased the uptake of heavy metals by the plant roots. The treatments did not significantly affect Pb uptake by plant roots and shoots and Hg uptake by plant shoots. AMF treatments significantly reduced the translocation factor (TF) value for Hg, bioconcentration factor (BCF) values for Cd and Pb, and removal efficiency (RE) values for Cd and Pb. AMF could effectively increase nutrient absorption in the plant shoots, reduce Cd, Hg, and Pb translocation in plant shoots, and reduce Cd, Hg, and Pb in the tailings.

Abstract

The Tanjung Lesung Special Economic Zone (SEZ) is a tourism area close to faults and active volcanoes. This location causes the Tanjung Lesung SEZ to have a high tsunami threat. In 2018, this area became an area affected by the Sunda Strait tsunami, which caused various losses, including casualties. This study aimed to examine the physical characteristics of the Tanjung Lesung coastal area, which has a tsunami threat. The physical characteristics in the research are elements that can affect the resilience of the tsunami disaster on the Tanjung Lesung coast. These include land use, topography, evacuation routes, and settlement conditions. This study used primary and secondary data obtained through government agencies and a field survey in 2021. The overlay analysis method on GIS was used to provide a spatial explanation of the physical characteristics of tsunami-prone areas. The study results showed that shrubs, a slope of 2-15%, and a height of 5-25 m above sea level dominate the area with the category of dangerous and very dangerous levels. The results also explained that there are settlements with wooden wall structures and cement floors located in very dangerous areas (with an area of 32.06  ha) and dangerous areas (with an area of 11.62 ha). Based on the analysis, there are three distinct categories in the research area. All three categories require coastal boundary planning that considers the tsunami threat to increase disaster resilience. The research results can be used to increase disaster resilience or spatial planning in coastal areas.

Abstract

Azo dyes are the most commonly used dyes in the textile industry and is classified as reactive dyes, including remazol dyes. Remazol dye creates additional reactions with fibrous substrates to produce ester bonds that give the fabric a bright colour. Remazol Black B (RBB) is a reactive dye from the Azo group. Remazol, also called a reactive vinyl sulfone dye which is widely used in the batik industry with black B, is its kind of colour. One of the biological treatments uses bioremediation techniques using fungi as a bioremediation agent. Therefore, this study aimed to screen and identify potential fungi that could degrade RBB using tannic acid as a qualitative screening and quantitative screening using a liquid medium containing various concentrations of RBB dye (250 ppm, 500 ppm, 1000 ppm, 1500 ppm). The results showed among ninety-eight fungal isolates, and six isolates were positive for laccase assay using tannic acid. Two of the six fungal isolates were identified as Aspergillus sp.1 (74BRT) and Aspergillus sp.2 (105PDL), which were selected for further study based on their high efficiency in decolourising RBB dye (96.89% and 91.21%). BLAST analysis of sequence data showed the identity of isolate 74BRT as Aspergillus tamarii, and isolate 105PDL as Aspergillus sclerotiorum. The efficiency of A. tamarii and A. sclerotiorum  to decolourise the batik effluent was up to 37.47% and 42.09%, respectively. The laccase assay of these two isolates showed that A. tamarii had the highest enzyme activity at 120 h, reaching 12.23 IU mL-1, while A. sclerotiorum reached 9.34 IU mL-1.

Abstract

Understanding soil characteristics is important to determine the alternative strategies of land management, particularly those related to the scheme of soil and water conservation. This study investigated soil characteristics from four land covers around the coal mining concession area located in South Kalimantan. A soil survey was conducted using a purposive sampling method with three replicates in each land cover. Soil samples that were taken at depths of 0-10 cm, 11-20 cm, and 21-30 cm, were composited before being brought to the laboratory to quantify their characteristics, such as texture and organic carbon content. Data analysis was processed using a non-parametric test with a significant level of 5%. Comparison average of soil characteristics between land covers was evaluated using the Kruskal-Wallis test and followed by Nemenyi-test. Results found that soil characteristics from four land covers significantly differed in texture and organic carbon content. The highest sand fraction was noted in shrubs (67.23±0.86%), while the greatest silt fraction was recorded in plantation forests (29.71±2.84%). Compared to other land covers, the clay content in plantation forests and reclamation area was relatively equal by around 53-54%. On another side, The highest soil organic carbon was found in plantation forests with ranging of (4.44±0.14%) followed by natural forests (4.24±0.62%), shrubs (3.38±0.09%), and reclamation area (1.14±0.09%). These findings indicated there were high variations of soil characteristics from different land covers around the coal mining concession area. Therefore, it is recommended for managers to apply adaptive strategies in supporting soil conservation efforts based on the soil characteristics in each site.

Abstract

Food safety and soil degradation were the reasons to treat contaminated soil. Shallots are high-value commodities, so cultivation is carried out intensively. Continuous use of agrochemicals can cause heavy metal contamination. This study aimed to investigate chromium removal, physiological characters, and yield of shallot (Allium ascalonicum L.) on biochar and mycorrhizae application on chromium-contaminated soil. A pot experiment was conducted at the screen house ex-farm of the Faculty of Agriculture, Jenderal Soedirman University. The treatments tested consisted of two factors. The first factor was biochar dosage (B) consisting of 4 levels, i.e., B0 = without biochar, B1 = 1.2 g biochar kg-1 of soil, B2 = 2.4 g biochar kg-1 of soil, and B3 = 4.8 g biochar kg-1 of soil. The second factor was mycorrhizae inoculation consisting of 3 levels, i.e., M0 = without mycorrhizae, M1 = 0.1 g mycorrhizae kg-1 of soil, M2= 0.2 g mycorrhizae kg-1 of soil. The twelve treatments were arranged in a randomized block design with three replications. The results showed that the application of 1.2 g, 2.4 g, and 4.8 g biochar kg-1 of soil had been able to increase plant height and the percentage of root infection. The application of mycorrhizae 0.1 g and 0.2 g mycorrhizae kg-1 of soil was able to increase plant height, percentage of root infection, and plant tissue P uptake. Both applications of biochar and mycorrhizae increased plant height and the percentage of root infection by mycorrhizae.

Abstract

The decline of land quality has an impact on the decline of productivity which in turn reduces production. This kind of thing happened to rice fields in the research area of Seririt District. The objective of this study was to evaluate the rice field quality in Seririt District, Buleleng Regency, Bali Province. The study used a survey method to take soil samples, followed by laboratory analysis for each homogeneous land unit (HLU). The HLU was determined by overlapping soil type maps, slope maps, and utility maps. Parameters analysed were bulk density, texture, porosity, water content, organic C, pH, cation exchange capacity (CEC), base saturation (BS), nutrients (total N, available P, and available K), and biomass C. The results of the laboratory analysis were compared with the criteria for soil quality based on ten minimum data sets (MDS) for each HLU. The results showed that the soil quality at the study site is classified as very good in HLU I with a soil quality index (SQI) of 18. This HLU is located in Rangdu and Ringdikit villages, with an area of 125.15 ha. Good SQI was observed on HLUs II, III, IV, V, VII, and VIII, respectively, located in Banjar Asem, Lokapaksa, Pangkung Paruk, Bestala, Ume Anyar, Mayong, Joanyar, the SQI value of 22-25 is 2,321.49 ha with the limiting factors of total N, total P, texture, and bulk density. The suggested rice field management plan is the addition of organic, nitrogen, and phosphate fertilisers.
