Abstract

This research investigated slope stability issues in Bulobulo Village, Barru Regency in Indonesia, which is known to experience very high landslide occurrences, particularly in steep slopes with seasonally altered overburden rocks through refraction seismic method and geotechnical analysis. This study conducted mechanical and physical soil tests in the laboratory, and the geophysics study investigated subsurface configuration. The set of data collected also reflected some seismic velocity anomalies, which are signs of variations in the arrangement of the substructure. A geotechnical investigation of the slope showed low cohesiveness and high water content, which were detrimental to stability. The factor of safety (FoS) calculated using the limit equilibrium technique established some slopes as being in a critical state and, hence, at risk of landslides. Such integration of methods allows one to make data-driven proposals for landslide prevention and provides a comprehensive comprehension of slope performance.

Abstract

The extraction and processing of aggregates in quarrying operations leads to environmental degradation through various engineering methods. This study investigated the geo-engineering properties of tertiary volcanic rocks mined from various sites in Sleman and Bantul District, Yogyakarta Province. A total of twelve rock samples were obtained from the study area. This study conducted mineralogical and geotechnical engineering investigations, including microscopic analysis, unconfined compressive strength (UCS) tests, abrasiveness tests (CAI), and rock abrasivity index (RAI) calculations. Mineralogical observation using polarisation microscopy indicated that the rock samples consist of quartz, plagioclase, lithic fragments, and volcanic glass. The UCS test showed varying rock strengths due to resistant minerals in the samples. Similarly, the CAI values varied and were influenced by the quartz mineral content, which is representative of resistant minerals. The Rock Abrasivity Index (RAI) calculation classified the samples as less abrasive, and this characteristic is also affected by quartz content. A significant correlation was observed between the quartz mineral content and the UCS, CAI, and RAI values. This relationship suggests that the quartz mineral content substantially affects the UCS, CAI, and RAI values of the rock samples in the study area. The findings of this study can be used to enhance mining practices and minimize their ecological impact.

Abstract

Inadequate industrial waste management has led to heavy metal contamination in agricultural lands, threatening food productivity and sustainability. This study aimed to evaluate the effect of organic fertilizer application on the phytoremediation of heavy metals (Pb and Cd) contaminated rice fields surrounding the industrial area of Pagak, Malang Regency. The study was initiated by identifying the distribution of Pb and Cd in soil, water, and rice plants. The soil identified with the highest Pb and Cd concentrations was then subjected to a phytoremediation experiment using Cordyline fruticose and Excoecaria cochinchinensis as metal accumulator plants. Organic fertilizers used for the evaluation of the phytoremediation effectiveness were chicken manure, Thitonia, and sugarcane waste. Phytoremediation effectiveness was evaluated based on the Bioaccumulation Factor (BAF) and Translocation Factor (TF). The results of the soil characterization study showed that Pb and Cd concentrations at soil depths of 0-20 cm and 20-40 cm exceeded the permissible limits, with Pb concentrations ranging from 41.62 to 74.93 ppm and Cd concentrations ranging from 0.58 to 1.10 ppm. The results of the phytoremediation experiment showed that Cordyline fruticose exhibited higher Pb and Cd absorption capacity than Excoecaria cochinchinensis at 30 and 60 days after planting), indicated by BAF values of >1. In all treatments, however, both plant species have TF values of <1, indicating that the two plant species are considered suitable for phytostabilization as heavy metals in the soils were more concentrated in the plant roots rather than in the plant shoots.

Abstract

Research on peatlands has become increasingly interesting in recent years, particularly in tropical regions. In these regions, including Indonesia, peatlands develop over sand and clay substrata and are widely utilized for oil palm cultivation. However, the influence of substratum type on palm yield remains poorly understood. This study aimed to a) investigate the morphological and physical characteristics of peat soils formed over sand and clay substrata and b) examine the relationship between peat soil substratum types (sand and clay) and oil palm production. Soil samples were collected from three blocks of an oil palm plantation in Pesisir Selatan, West Sumatra, and then were analyzed in a soil laboratory. Additionally, fresh fruit bunch (FFB) yield data from the past six years for each block were also collected from the plantation records. The results indicated that peat soil formed over clay substratum (L) was more mature (sapric), with lower fiber content, higher ash content, lower organic matter content, higher moisture content, and higher pH compared to peat soils formed over sand substratum (P1 and P2). The average annual fresh fruit bunch production from palms cultivated on peat soil with a clay substratum (19.68-20.85 t/ha/yr) was 11-16% higher than that of palms on peat soil with sand substratum (23.52 t/ha/yr). Among the peat soil properties analyzed, water content, ash content, and soil pH had the most significant positive effects on oil palm production. These findings highlight the critical role of substratum type in influencing oil palm yield.

Abstract

The study was conducted in three different ecosystems: mamar (a typical local ecosystem close to water catchment areas), farm, and coastal ecosystems. In each ecosystem, soil samples were taken from the rhizosphere of five different plants to investigate the occurrence of PSM, molecularly identify the potential isolates, and evaluate their ability to increase soil phosphorus (P) availability and mungbean yield. The highest population of phosphate-solubilizing bacteria (PSB) was found in the mamar ecosystem. Phosphate-solubilizing fungi were only found in the farm and coastal ecosystems, with low populations, and restricted to the rhizosphere of a few plants. The number of PSB isolates was higher in the coastal ecosystem, followed by the farm and mamar ecosystems. The phosphate solubilizing index of the isolate was quite high, ranging from 210 to 300. One isolate from the five molecularly selected isolates from Kupang regency was identified as Aspergillus sp. (cassava rhizosphere origin), one isolate from the farm ecosystem (Moringa rhizosphere origin), and three isolates from the coastal ecosystem (Jatropha gossypiifolioa, Scheichera oleosa and Calotropis gigantea L. rhizosphere origin) were all identified as Pseudomonas sp. Two selected isolates from a previous study in Timor Tengah Selatan regency, collected from the mamar ecosystem (bamboo and Leuchaena leucocephala rhizosphere), were both identified as Acinetobacter baumannii. Inoculation of PSB resulted in higher available soil P compared to the uninoculated treatment. PSB inoculation also provided higher tissue P than the uninoculated treatment. PSB from coastal areas gave the highest pod weight and seed weight compared to other inoculation treatments.

Abstract

The use of geosynthetic containers (geotubes) is a promising technology for the elimination of environmental pollution from industrial and subsurface use waste, based on the storage and dewatering of liquefied waste inside geosynthetic shells. The problem of environmental pollution from the mining industry is relevant since this industry is one of the leading areas of the world economy. Geotubes have found their application to solve some of the challenges facing the industry. However, in most cases, geotubes are not integrated into technological processes and do not use all the possibilities of their application. The data, effective methods, and technologies, examples of applications in various areas of the mining industry. he main advantages and disadvantages of technologies are presented. Examples of the use of geotubes in mining, including the development of placer deposits, the construction of structures, the operation of sludge storages, dumps, are considered.

Abstract

This study examined the potential of repurposing agricultural waste as biofilm carriers in Moving Bed Biofilm Reactors (MBBRs) for wastewater treatment. The goal of this experimental research was to reduce the wastewater treatment costs. This research focused on two agricultural by-products: banana stems and corn stalks. These materials were tested as biofilm carriers in a laboratory-scale MBBR setup. Banana stems and corn stalks were prepared to facilitate biofilm formation before being incorporated into the reactor. Results revealed that banana stems achieved reductions of 27% in COD and 32% in BOD, with TSS dropping by 69% during treatment at a filling ratio of 40%. Despite these reductions, the low density of banana stems led to less effective pollutant removal. In contrast, corn stalks demonstrated superior performance, achieving 69% and 83.6% reductions in COD and BOD, respectively, and a 66.7% reduction in TSS at a 40% filling ratio. The higher surface area and better integration of corn stalks with wastewater contributed to more efficient biofilm formation and pollutant degradation than banana stems.

Abstract

Heavy metals in high concentrations from industrial areas are deposited in the soil and, as a result of ecosystem interrelationships, enter and are harmful to living beings. To determine if there is translocation of metals from the soil to herbivorous animals, the team of the Laboratory of Learning, Technology and Democratization in Soils and Communities (LAPTES) conducted a first exploratory study and then a complementary study of the translocation of heavy metals such as Copper (Cu), Arsenic (As), Cadmium (Cd) and Lead (Pb) in localities near the Ventanas Industrial Complex (CIV). Fecal samples were collected from different points of the La Greda School, using standard methods for the determination of heavy metals in certified laboratories. The results were analyzed using correlation coefficients, Spearman correlation matrix, and descriptive statistics. It was shown that there was a correlation between the presence of metals in the soil and the feces of herbivorous animals. It is concluded that there would be a risk in the hunting and consumption of local lagomorphs on contaminated soils, affecting food security, making it necessary to strengthen environmental education through soil remediation in contaminated territories, considering the active participation of the communities.
