Abstract

This paper aims to characterize and test the stability of sulfuric natural water (SNW) from Sebau East Lombok as a sulfidation agent for several dissolved metals (Mn, Cu, Pb and Fe). The parameters used for SNW characterization are temperature, pH, DO, BOD, COD, TSS, and TDS. The sample was divided into two categories, namely the sample with preservation treatment and the sample without preservation, to study the stability of SNW. The SNW stability was determined by observing the SNW parameters in both samples at a storage time of 5, 10, 15 and 20 days and reacting them with dissolved metals. The SNW with preservation had reduced sulphide levels from day 1 to day 20, ranging from 59.24 mg/L to 17.70 mg/L, whereas the sample without preservation had decreased sulphide concentration from 52.46 mg/L to 9.56 mg/L. Furthermore, the SNW with preservation has a relatively superior metal reduction ratio than the sample without preservation. The maximum value of the deposition ratio for Mn metal was obtained on the fifth day with 57.60%, 83.45% for Cu, and 91.87% for Pb. This trend is not applicable for Fe, whereas the highest reduction (87.23%) was obtained on the the15th day's storage.

Abstract

Reclamation (revegetation) activities must be carried out upon the completion of mining. Limestone dust can affect the physical, chemical, and biological properties of soil. To increase the growth rate of non-wood product species such as coffee, biological fertilizers of mycorrhiza are introduced to the reclamation site. The goal of this study is to examine the effects of limestone dust covering former mines and different doses of mycorrhizal biological fertilizers on the growth of coffee seedlings. The research was conducted using the Randomized Complete Block Design method. Research areas were divided into groups/blocks consisting of soil without limestone dust, dust-covered 0-2.5 cm, and dust-covered 0-5 cm. The groups were treated with the addition of 10 g, 15 g and 20 g mycorrhizal biological fertilizers with five replications each. NPK inorganic fertilizer was given every one month to all treatments. The parameters observed from the growth of coffee seedlings were plant height, Stem diameter, and number of leaves. Based on the results, limestone dust influenced soil conditions such as silt, clay, pH, organic C, bulk density, and C/N ratio. In addition, limestone dust affected the plant height and number of leaves of coffee seedlings compared to those grown in an area without dust. Differences in the amount of mycorrhizal biologic fertilizers were significant (p<0.05) and tended to increase for the parameters of height and diameter of coffee seedlings. However, the difference in the dose of mycorrhizal biological fertilizers has been shown to significantly (p<0.05) decrease the number of leaves.

Abstract

Rivers on Java Island are one of the water supply sources to meet the surrounding population's water needs. However, only large, high-priority rivers underwent a comprehensive water quality assessment. Rivers that aren't a priority are rarely examined, such as sub-watersheds in Kuntulan, Rejoso. Upper Serayu, Gajahwong, and Glondong. The surrounding community utilizes these five watersheds for irrigation, industry, and domestic. Hence, analyzing the water quality index in the five watersheds during the dry season is necessary. The method used in this research is a comparison of the water quality results between the standards of the Indonesian government and WHO, as well as a comparison of the Water Quality Index (WQI) and Pollution Index (PIj). The method often used in Indonesia is PIj, while WQI is more global and hardly used. The difference in the two ways is expected to provide variations in the water quality index. The water quality parameters were pH, TDS, TSS, COD, PO43-, NO3-, Total Coliform, Temperature, and EC. Comparing water quality with water quality standards in the five watersheds shows that several samples exceed the standard. WQI result shows that all river water in the five watersheds belongs to the excellent classification. A different result from the PIj index shows that the five watersheds were dominantly moderately polluted, with several samples considered polluted and extremely polluted. Differences in the index formula and water quality standards cause these different results. The results of the analysis show that the PIj index is more representative than the WQI as the PIj index shows the suitability of the classification comparison of water quality values with water quality standards compared to WQI.

Abstract

One of the indicators of land productivity assessment is soil fertility. The causes of infertile soil have been widely reported. This study aimed to evaluate soil fertility using the Soil Fertility Capability Classification (SFCC) approach and to determine the relationship between soil morphological and physiochemical properties and soil fertility. The research was conducted in North Galela Sub-district, North Halmahera Regency. The research framework began with the interpretation of thematic maps, surveys, field observations, and the making of soil fertility evaluation maps. Soil sampling was carried out based on the stratified random sampling method and supported by laboratory measurements according to USDA international standards. The research result showed that the research area had 14 soil fertility statuses. The fertility classes having the most significant limiting factor were loamy texture (Ø<0.002 mm), rock surface, gravel subsoil, moderate salinity (0.2-0.4 mS cm-1), low exchangeable K (<20 cmol(+) kg-1), and sloping slope (8%) with Lithic Haprendolls type and loamy texture (Ø<0.002 mm), subsoil >15% rock outcrop, moderate salinity (0.2-0,4 mS cm-1), Na saturation >15%, and a rather steep slope (14%) with Lithic Eutrudepts type. Both of these classes have a top layer texture, and the bottom layer contains clay <35%, with limiting factors of hard layer inhibiting root to a depth of 50 cm, extremely low nutrient reserve, low electrical conductivity (EC) and high Na. The limiting factors found in North Galela Sub-district were hard root-restricting layer, exchangeable K, electrical conductivity, Na saturation, slope, and gravel.

Abstract

The Upstream Citarum watershed has a critical essential role in maintaining the quality and quantity of its water resources, which are a source of drinking water, agriculture, fisheries, irrigation, and electricity generation. The upstream watershed acts as a water catchment area that contributes as a place to accommodate the availability of water, especially during the dry season, and also as a protector of the entire area, both downstream and middle, so that the carrying capacity of the ecological balance can be protected. The increasing total population was inversely related to the condition of land use which is decreasing in quality, so to fulfill these needs, there was a land conversion that caused changes in land use. The Landsat-8 satellite imagery, SPOT 7, and spatial planning maps were used to analyze the suitability and incompatibility of land use with spatial pattern plans, evaluation, and directions for controlling the use of space. The result of the most extensive existing land use in the Upstream Citarum watershed in 2021 used for fields is 30% of the total area of 66,831.66 ha. Meanwhile, the spatial pattern plan was classified into protected and cultivated areas. The built-up area has the largest area, 35% or 75,223.96 ha. The results of the suitability of land use classes obtained that the level of suitability between the existing land use and the spatial pattern plan from the Maps of Regional Spatial Planning with the appropriate class was 52.50% or 96,205.43 ha, and the unsuitable class was 47.50% or 87,028.75 ha.

Abstract

A biodegradable seedling container was developed to minimize plastic waste in the field during post-mining land revegetation activities. Therefore, this study aims to evaluate the physiological response and growth of Samanea saman grown in a biodegradable seedling container filled with post-silica mined soil media. A factorial experimental design was used with two factors, namely (1) basic raw materials, namely recycled newspaper, compost, and cocopeat, and (2) size of raw materials, including 5 mesh, 10 mesh, and 8 mesh. The parameters measured were photosynthetic rate, leaf greenness index, transpiration rate, height, and diameter of S. saman seedlings. The results showed that the interaction between the composition and size of basic raw materials of the biodegradable seedling container significantly increased the photosynthetic rate, leaf greenness index, transpiration rate, height, and diameter of seedlings. There was also a positive correlation between the rate of photosynthetic and leaf greenness index (r = 0.838). Furthermore, the C/N ratio of the biodegradable pot varied depending on the composition of materials used. After two months, the C/N ratio decreased, indicating that decomposition processes had occurred. Analysis of the biodegradable seedling container showed that it contains less than 0.08 mg Pb kg-1, which was considered a non-toxic element for plant growth.

Abstract

Organic matter (OM) has a very crucial role in the management of acid mine drainage (AMD) using a passive treatment system, although information on the use of this system in different reclaimed-mining soils (RMS) is very limited. Therefore, this study aimed to determine the effect of adding OM to RMS with different characteristics. It was carried out by adding only OM or in combination with coal fly ash (CFA) to two RMS with different characteristics (Palam and Cempaka Soils) and quartz sand (control) in a batch reactor experiment. This was followed by the incubation of the mixture of soil/quartz-OM or soil/quartz-OM-CFA at 60% water holding capacity for 15 days. After incubation, AMD slowly flowed into the reactor, and its pH in the reactor was monitored every day for 30 days, while the concentrations of Fe (iron), Al (aluminum), and Mn (manganese) were measured on the 30th day. The results showed that the application of OM on Palam Soil only increased AMD pH by 0.38 units, while Cempaka Soil and quartz sand increased by 4.83 and 5.36 units, respectively. The addition of OM to Cempaka Soil and quartz sand also showed a higher reduction in heavy metals concentration in AMD than those in Palam Soil. It was also discovered that the application of OM combined with CFA led to a higher improvement in AMD quality than only using OM. This study demonstrated that the effect of OM addition on increasing pH and decreasing metal concentration on AAT management with the passive treatment system is controlled by soil characteristics.

Abstract

Landslides are a recurring phenomenon that disrupts the natural environment and causes yearly property damage, economic losses, and fatalities. The damage is expected to increase due to deforestation rates, population growth, agriculture, slope-building infrastructure expansion, and global climate change. This study assesses the susceptibility to landslides through Weight of Evidence (WoE) and Frequency Ratio (FR) methods in the Temanggung Regency, Central Java Province, Indonesia, that located on the slopes of two active volcanoes. Initially, a landslide record and the input parameters of the landslide controlling factors were prepared from field surveys, remote sensing data, and secondary data and processed by a geographic information system (GIS). Six landslide parameters in thematic layer maps were selected to develop landslide susceptibility: slope, lithology type, geological structure density, land cover, and rainfall. According to the WoE and FR models, a landslide susceptibility zoning map was classified into four landslide-prone zones from low to very high. Finally, the success and predictive rate curves method confirmed the landslide susceptibility maps to check the model accuracy. The results showed that the landslide susceptibility map using the WoE method had better accuracy than the FR method, with a success rate of 78.48% and a prediction rate of 81.1%. In comparison, the FR method was 74.53% for the success rate and 78.48% for the prediction rate. These landslide susceptibility maps can be used as a guideline to develop land-use planning and landslide disaster mitigation.

Abstract

The decline of the forest cover due to deforestation and agricultural expansion in Sudan has reached a critical situation. Taungya agroforestry systems have been used as a strategy to safeguard against this process, allowing farmers to cultivate their subsistence crops at the early stage of tree plantations. The current study research tackled Nabag Forest Reserve (NFR) as a case study to assess and explore Taungya agroforestry system as a practice used for forest rehabilitation in the study area. Satellite images of Landsat 5 Thematic Mapper, and Landsat 8 Operational Land Imager/Thermal Infrared Sensor of 1991, 2001, 2011, and 2021 were used to generate forest cover maps. Both unsupervised and supervised classification, as well as ground truth points, were applied to classify the vegetation cover in NFR as dense forest (DF), light forest (LF), agricultural field (AF), and bare land (BL). The results showed that two trends of forest cover changes occurred in NFR between 1991-2001 and 2011-2021. It was well explored that through Taungya agroforestry, there was a considerable increase in forest cover over this period. This could be clearly detected by increasing dense forest and light forest cover by 1041.73 ha (24.95%) and 2.95 ha (0.07%), respectively and decreasing of bare land and agricultural field by 409.79 ha (9.81%) and 634.52 ha (15.15%) during the addressed period. The findings of the study indicated that Taungya agroforestry system could be a feasible land-use alternative for forest recovery in the dry land of Sudan.

Abstract

The Ethiopian government has exerted efforts to rehabilitate degraded agricultural lands using a range of sustainable land management (SLM) initiatives to enhance agricultural productivity. One of the key components was improved structural soil and water conservation (SWC) technologies. This study examines the effects of continuous SLM practices on agricultural land productivity, with particular emphasis on SWC technology adoption in Central Ethiopia. The analysis was based on the data collected from 525 sample household surveys in two districts, namely Kewet and Sebeta-hawas. A propensity score matching (PSM) model was used to investigate the effects on treated and non-treated plots. The study findings revealed a substantial and positive effect on treated agricultural plots compared to non-treated ones in the Kewet district. At the same time, the difference was found positive but not significant in the Sebeta-hawas counterpart. The insignificant impacts are justified because SWC efforts focused on constructing structures rather than tailoring them with soil-replenishment and productivity enhancement functions. The important conclusion is that continuous SWC adoption efforts positively impact agricultural productivity; however, its effect is more noticeable when SWC structures are integrated with productivity enhancement functions and applied in low moisture areas. Thus, policymakers and project planners should consider the role of integrating physical SWC structures with soil replenishment and agronomic activities.
