Abstract

Vegetations accumulate carbon (C) from the atmosphere in the form of tree biomass, producing litter which then becomes the main input of soil organic matter. The accumulation of soil organic matter provides food and energy for soil macrofauna to help maintain soil fertility. Total C accumulation is affected by land use changes which can then reduce soil ecosystem and ecological functioning. This study examined the impact of land use conversion from monoculture sugarcane to a tree-based agroforestry system. The results showed that the land use changes affected soil texture, bulk density, soil organic matter, and total C sequestration. The total C sequestration under 5 years old sengon (Paraserianthes moluccana) agroforestry system was almost double that of total C sequestration 2 times or even 5 times ratooned monoculture sugarcane (Saccharum officinarum). The lowest IVI of soil macrofauna was detected under 1-year-old sengon agroforestry system before it was getting lowered under a longer period of cultivation, whilst the highest population was detected under 5 years old Sengon. Multivariate analysis, which was employed to detect the impact of land use changes, could cluster and group the effect of treatments based on selected variables such as soil physical, chemicals, and soil macrofauna structure and diversity, which accounted for 97.75% of the total variance. There was a strong relationship between the abundance of Formicidae sp. and Carabidae sp.

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

Many factors cause increasing Pb contamination in soils, including intensive crop production, motor vehicle exhaust gas around agricultural land areas, or irrigation mixed with household. An effort is needed to minimize Pb contamination in soils. This experiment aimed to examine the potential of Crotalaria juncea L. intercropped for minimizing the accumulation of Pb in vegetable crops grown intensively using agrochemicals. The treatments tested were monoculture of Brassica rapa, monoculture of Phaseolus vulgaris, monoculture of C.juncea, intercropping C. juncea with B.rapa, and intercropping C. juncea  with P. vulgaris. Results of the study showed that planting of C. juncea reduced the total dry weight of B.rapa by 33.47% and increased the total dry weight of P. vulgaris by 17.41% compared to monoculture. Intercropping of B rapa or P. vulgaris with C. juncea reduced the total Pb concentration of B. rapa by 45.64%, and that of P. vulgaris by 16.22%. Planting of C. juncea reduced the Pb concentration in B. rapa by 21.23% (Pb 0.89 mg kg-1) and that in P. vulgaris by 76.03% (Pb 0.93 mg    kg-1). Monoculture planting of C.juncea and intercropping of C. juncea with B. rapa or P. vulgaris reduced the concentration of available Pb and total Pb in the soil to not detected value, compared to monoculture planting of B. rapa and P. vulgaris.

Abstract

With limited land availability, the land use and management on the small island must be sustainable. Sulabesi Island, with an area of <2000 km2, makes it one of the small islands in North Maluku and a remote island. This condition makes Sulabesi vulnerable to land loss and faced with adverse threats both environmentally and socio-economically if the allocation of residential places does not manage appropriately. The study aimed to identify the distribution of coastal settlement land with the characteristics of the island landscape, including analyzing its suitability to coastal boundaries and recommending directions for the development of coastal settlements on Sulabesi island. The method of this study used the geographic information system (GIS) to provide a spatial picture with overlaying and buffering techniques. The data analysis used topography, slope, distribution of settlements, and coastlines with collected data sources from government agencies and remote sensing, including field observations. The analysis results showed that the settlements scattered Sulabesi island randomly and separately with linear patterns, clustering, and combinations. The distribution in the island landscape was with a dominant height at 0-200 m and a slope of 0-30% or is a flat-steep plain. Besides that also shows a mismatch of utilization between the residence and the coastal border area, so land use for future settlements can do on the more proportional ground, especially outside the coastal buffer area. The results of this study's analysis can be used for further direction in regional planning and land management on small islands.

Abstract

The rise of the batik industry in Jambi Province causes the accumulation of waste in the environment. Disposal of batik dye wastewater directly into the environment is one source of heavy metals entering the river. Palm Oil Fuel Ash (POFA), as a part of waste originating from combustion residues of oil palm, is potential to be used as a low-cost adsorbent in overcoming the batik dye wastewater problem. The POFA is also potential to be used in the removal of heavy metals and chemical and organic compounds in industrial waste treatment. This paper reported the potential use of POFA and the modification of POFA as batik dye adsorbents in overcoming waste problems from the batik industry. Results of this study showed that POFA could adsorb the dye in batik waste with up to 22% removal efficiency and adsorption capacity up to 62 mg/g. The isotherm adsorption in this study was in accordance with the Freundlich model that showed adsorption occurred at multi-layer and heterogeneous surfaces. The adsorption process occurred endothermically and spontaneously.

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

Sandy loam soils contain low organic carbon and have low ion adsorption capacity. Under certain conditions, the soils contain heavy metals that are harmful to plants. Soil amendments such as biosilica and humic acid from natural sources are expected to increase the soil adsorption capacity to heavy metals. A simulation experiment consisting of two factors was conducted to explore the effectiveness of humic and biosilica, as soil amendments, in adsorbing heavy metals from soils. The first factor was biosilica dose composing 0 t ha-1 (S0), 0.5 t ha-1 (S1), 1 t ha-1 (S2), and 1.5 t ha-1 (S3). The second factor was the humic acid dose composing 0 kg ha-1 (H0), 20 kg ha-1 (H1), 40 kg ha-1 (H2), and 60 kg ha-1 (H3). The humic acid and biosilica were applied to soil contaminated with Pb and Cd. The results showed that the combination of 0.5 t biosilica ha-1 (S1) and 20 kg humic acid ha-1 (H1) significantly increased soil pH, organic C content, cation exchange capacity, and reduced the availability of Pb and Cd at 90 days after treatment. The Pb and Cd contents in plant tissue decreased from roots to grains. Humic acid treatment was more effective in absorbing Pb of 86.89-90.49% and Cd of 71.47-76.33% than other treatments.

Abstract

Determining the oil palm dead roots contribution to total (Rt) and heterotrophic (Rh) respiration as a source of greenhouse gas/GHG emission in tropical peatland is urgently required, as well as predicting their magnitude to cope with difficulties of direct in-situ measurement. This study is designed to simulate the CO2 flux emitted from oil palm dead roots/Rdr in tropical peatland as affected by water content/WC and residence time/RT. The dead oil palm roots were cleaned, treated with control/15, 100, 150, 300, and 450%WC, and then incubated for three months. CO2 flux measurement, C, N, and CN ratio determination were conducted every month. This study demonstrated the importance Rdr among other CO2 emission sources, ranging from 0.05-2.3 Mg CO2 ha-1 year-1 with an average of 0.7 Mg CO2 ha-1 year-1. Rdr contribution for literature Rt and Rh were around 0.3 to 1.3 and 0.9 to 3.5%, respectively. As a product of microbial respiration, Rdr was affected by WC and RT, supported by analysis of variance, linear mixed effect model/REML, and multivariate analysis. 100-150%WC resulting in significant and highest Rdr, whereas the increase (300-450%WC) or decrease (15%WC) would generate lower emission. Rdr culminated in the first month after incubation; meanwhile, it declined in the following months. This study also emphasized non-linear relationships between CO2 flux and other root properties, which can be modeled conveniently using non-linear approach, particularly using polynomial and artificial intelligence-based models. The simulation presented in this study served as an initial attempt to separate Rdr from Rh, as well as to predict CO2 flux with reasonable accuracy and interpretable methods.

Abstract

Vegetation can be an important indicator of ecosystem change, the influence of anthropogenic and non-anthropogenic factors. Therefore, it is important to study the dynamics of vegetation changes. One technique that can be used for vegetation analysis is the Normalized Difference Vegetation Index (NDVI). NDVI is an indicator of the active biomass that helps distinguish vegetation from other land cover and can provide information about changes in Spatio-temporal vegetation dynamics, thus allowing for assessment of the ecological conditions. This study aimed to investigate the dynamic of vegetation in the Sangkub watershed area located in North Sulawesi Province. This analysis used geospatial technology with the NDVI method, utilizing Landsat 5 and Landsat 8 satellite imagery data in three periods the year 2000, 2015, and 2020. The results showed that vegetation cover of the Sangkub watershed decreased substantially, whereas the non-vegetated area increased gradually over time.

Abstract

Leakage or seepage in reservoirs and dams has the potential for structural instabilities persuaded by water leakage pathways and linked to economic consequences. An environmental isotopic and hydrochemical research was conducted to determine the source and origin of seepages on the tunnel of Pandanduri dam, Lombok Island, Indonesia. This study aimed to examine the source of the tunnel leak on the dam site and the origin or source of water at the point of leakage based on water chemistry data and stable isotopes. To identify the source of the leakage water in the tunnel dam, 33 samples of the leakage water, groundwater, reservoir water, river water, and rainfall water were taken for chemical and isotopic composition analysis. The field measured the reservoir level, spring discharges, and physicochemical parameters (EC, pH, TDS, TSS). The physicochemical parameters show that the leakages water is similar to reservoir water. The types of leakage water in the tunnel belong to alkaline water, predominantly sulfate-chloride. This type of water is deep groundwater with a higher sulfate and chloride concentration than surface water or shallow groundwater. Hydrochemical and isotope analysis showed that water origin at leakage points is dominated by groundwater.
