Abstract

Amalgamation in the processing of community gold mines may leave slurry waste with the potential for heavy metal contamination of the environment. Technical studies for handling these wastes are very necessary to process the waste using a simple and applicable manner in the community. The purpose of this study was to examine the coagulation-adsorption technique of liquid waste from the amalgamation process. Slurry waste samples from the amalgamation process were collected from amalgamation sites in Boto Village, Wonogiri regency which had the highest Hg and Pb levels in the slurry. The coagulation-adsorption process is carried out by a continuous process with the gravitational flow because the area of the amalgamation process has a steep slope.  Coagulation of particles in the slurry used two kinds of natural ingredients, i.e. papaya seed, and moringa seed extracts.  The adsorption was conducted using two types of minerals, i.e. Ca-bentonite and zeolite which had been activated. The results of this study showed that the coagulation process was a simple process to purify amalgamation slurry waste and reduce the levels of Fe, Mn, Hg, and Pb metals.  Then the following step by using the absorption process to produce clear water from amalgamation liquid waste and reduce the levels of Fe and Mn metals. Coagulation using papaya seeds might purify amalgamation slurry waste and reduce heavy metal content of Fe 99.996%; Mn 99.994%; Pb 100%; Hg 100%. Based on these results, the Hg and Pb metals were metals that were very easy to settle. Adsorption on the liquid result of the coagulation process using unactivated zeolite reduced the metal content of Fe> 99.40% and Mn> 88.69%.

Abstract

Phytoremediation is one of the most effective and environmental-friendly methods in retrieving oil-contaminated soil. The decline of Total Petroleum Hydrocarbon (TPH) oil in the phytoremediation process will be accelerated by Oil Spill Dispersant (OSD) as a surfactant and the use of Ricinus communis L. plant. Commercial OSD products used in the remediation process are S200 OSD which contains LAS surfactant, which is a US EPA recommendation and is known to be less environmental-friendly, so SBRC-IPB develops OSD containing palm oil surfactants and is environmental-friendly. The purpose of this study was to determine the performance of OSD and R. communis to reduce TPH. This study used a completely randomized design with two factors, namely OSD and plant use. The results of this study indicated that OSD from SBRC-IPB improved plant growth, increased dry plant biomass, accelerated the decrease in TPH and increased the bacterial population compared to the S200 OSD and control. The combination of OSD from SBRC and R. communis was able to degrade TPH better than S200 OSD, with and without R. communis, with TPH concentrations of 30,000 ppm (3%) to 2,333 ppm (0.2%) for 20 weeks. This showed that the use of OSD was able to provide a positive response in the phytoremediation process of land contaminated with petroleum

Abstract

Direct seeding is considered as an option for afforestation programs to rehabilitate degraded lands. However, scant knowledge is available on the effect of seed sowing techniques on the germination of different woody plants in a semi-arid degraded area. Therefore, the objectives of this study paper are 1) to evaluate the effects of broadcasting vs seed bury on the germination of 15 different woody plant species in a degraded semi-arid area 2) to select woody plants that can result in higher germination percent in the field for restoration projects. To achieve the objectives, a study was carried out in the field, with a randomized complete block design (RCBD). One-way ANOVA, t-test and descriptive statistics were used to analyze the data. The result indicated that the average germination percent for buried and broadcasted seeds were 18.1% and 5.2%, respectively. Among the broadcasted species seeds, Schinus molle achieved the highest germination (23.3%) while Terminalia browni achieved the lowest germination (0.25%). Among the different species seeds that were buried, Dolanix regia achieved the lowest germination (1.5%) while Sesbania sesban resulted in the highest germination (64%). The t-test result revealed a significant difference in the mean germination of the broadcasted and buried seeds (p<0.05). The ANOVA result also revealed significant differences in the germination of the different families of the species. For most of the studied species (86%), seed bury has resulted in higher germination percent relative to the broadcasted seeds. Therefore, it is recommended that in semi-arid degraded land, it could be better to apply seed bury than the broadcasting when there is an objective to use direct seeding for afforestation.

Abstract

Maize is one of the food crop commodities that can take a role in the development of the agricultural sector. The purpose of this research was to know the effect of pyraclostrobin and nitrogen on the maize plant. The experimental design used in this study was a factorial completely randomized block design with three replications. The first factor was pyraclostrobin (P) that consisted of P0 = no pyraclostrobin application, and P1 = foliar spray of pryraclostrobin 400 mL/ha. The second factor was nitrogen application (N) that consisted of N0 = without N fertilizer, N30 = 30 kg N/ha, N60 = 60 kg N/ha, N90 = 90 kg N/ha, and N120 = 120 kg N/ha. The data was focused on the plant height, flowering and earing age, protein and amylose content of the seed, respectively. Data were analyzed by variance analysis followed by. analysis of the least significant difference (LSD) at the level of 5%. Nitrogen application increased protein content but reduced amylose content. Pyraclostrobin application that significantly increased the amylose content even in the high nitrogen application dosage

Abstract

Tailings are the parent material residues resulted from a separation process of valuable minerals containing copper, gold and silver. This separation process is carried out mechanically by destroying copper, gold and silver rocks on the Grasberg plateau. However, in the production process of tailing materials from Wanagon and Aghawagon rivers, there was also non-tailing material mixed with tailing materials. This condition cannot be avoided due to high and intensive rainfall so that non-tailing material from an ex-mine excavation in the form of overburden can flow naturally through the river flow system from the highlands to the lowlands of ModADA. Acid Mine Drainage (AMD) is one of the important impacts of mining activities that must be managed because it has an impact on the aquatic environment or groundwater, and once it has been formed it will be difficult to stop unless one of the components runs out. The study was carried out from 2005 to 2014 at several representative locations in ModADA included inactive tailings at MP 27 and MP 21, as well as active tailings at WA 225, WA 185, and WA 160. The average heavy metal content in WA 225, WA 185, WA 160 included in the criteria of class C, namely As (> 33 mg/kg), Cu (> 150 mg/kg), Pb (> 130 mg/kg), and Zn (> 460 mg/kg). Another heavy metal categorized as class B was Cd (1-5 mg/kg), while class A consisted of Cr (<43 mg/kg), Hg (<0.2 mg/kg), and Ni (<23 mg/kg). At WA 185, The ANC/MPA ratio at WA 185 < 1.5 was 0.97 (0-20 cm) and increased slightly to 1.59 (20-40 cm). The ANC/MPA ratio < 1.5 shows a higher acid-forming ability (MPA) than the ability to neutralize acid (ANC). The average heavy metal content in MP 27 is lower in concentration, except Cu which included in class C (> 150 mg/kg) which is similar to the host rock mined and involved in the tailings flow from MP 74. The Cu concentration at MP 21 decreased drastically, except for As which included in class C (> 33 mg/kg). The ANC/MPA ratio at MP 21 was 1.92 (0-20 cm) and slightly increased to 2.22 (20-40 cm), while MP 21 has the ANC/MPA ratio at 12.61 (0- 20 cm), and decreased to 4.34 (20-40 cm).

Abstract

DEM is a digital model that provides topographic information. DEM can be made from terrestrial surveys, aerial photography, video, optical, and radar satellites, LIDAR and multidata combination. In general, DEM can be in the form of DSM and DTM. This study aims to explain the classification of DEM based on terrestrial and non-terrestrial, the methods of DEM extraction, vertical accuracy, data formats, and technological trends. The methods of DEM extraction discussed include stereo, interferometry, DEM combination, videogrammetry, and terrestrial data interpolation. In addition, a comparison of vertical accuracy is also carried out with several methods of its extraction. DEM can be used for various applications involving land surface, especially for 3D modeling, spatial planning, geology, topography, and so on. This DEM is used to support the activities of inland waters on Rote islands.

Abstract

Top soil was rich in nutrients for plant growth. Upper soil loss due to mining is a serious problem. The remaining soil was subordinate land which has poor soil characteristics and low productivity. This study aimed to improve the characteristics of mined soils by providing soil amelioration. The study was conducted in a former brick mining area in the village of Potorono Banguntapan, Yogyakarta, Indonesia. The study consisted of two stages. The first stage was a pot experiment using soils from a former brick mining area. The soil was mixed with coconut shell biochar as an ameliorant material at doses of 0, 10, 15 and 20 t/ha and incubated for 1, 2 and 3 months. The second phase of research was a demo farm. The demo farm aimed to compare the best results of the use of biochar in the first stage of this study with organic matter application in the second phase of the study. The organic matters used were cow dung and bagasse. Each of the two types of organic matter was applied at a rate of 15 t/ha. The organic matters were incorporated into the soil in a demo farm plot of 4x4 m2 size in 1, 2 and 3 months. The results showed that application of coconut shell biochar ameliorant at a dose of 15 t/ha increased soil organic-C by 0.78% at two months of incubation, while soil cation exchange capacity increased at three months of incubation. The yield of plants obtained from the soil previously applied with coconut shell biochar was better than that applied with cow dung and bagasse as organic matters.

Abstract

Coal mining is carried out with an open system that is dredging topsoil, and then taken the coal material. In 2016, the Indonesian Center for Agricultural Land Resources Research and Development conducted a survey, mapping and characterization of ex-coal mine areas in Tapin, Tabalong, Balangan, and Hulu Sungai Selatan regencies. This paper aimed to provide information based on the soil biophysical characteristics on ex-coal mine lands and to assess the land suitability for agricultural crops. The land characteristics obtained were then matched with the criteria of quality/suitability land for agricultural crops. The ex-coal mine lands in the four regencies cover an area of 17,141 ha. The landform characteristics have changed, namely voids and piles of excavated products in the form of small piles to hilly called anthropogenic landforms. According to Soil Taxonomy, the soil is classified as anthropic soil that was formed from material transported by humans, as Endoaquents Anthroportic, Epiaquents Anthroportic, and Udorthents Anthroportic. The heavy metals found were Pb, Hg, and Cd that varied from low to high uneven both vertically and horizontally. The land suitability class of Suitable (S) for dryland food crops, vegetable crops and forage crops covered 12,606 ha, while for annual crops covered 14,158 ha. The land suitability class is classified as Marginally suitable (S3), and the remaining as Not suitable (N). Based on the biophysical conditions, the ex-coal mine area requires considerable land reclamation and rehabilitation efforts, both for the restoration of soil chemical and physical properties.

Abstract

The need for irrigation water is influenced by soil water content or more precisely by available water (pF 2.5 and pF 4.2). There is a need for technological breakthroughs in using Unmanned Aerial Vehicle (UAV) to identify water content quickly and broadly and accurately. The study was conducted in an area of ±18 hectares in the Sisim Sub Watershed in September 2019 at 09.00 a.m. Aerial photographs were taken at an altitude of 100 m with DJI Phantom Pro 3.0. The number of observation points was 75 points, where 15 points for validation were calculated based on the map scale. Photo processing was made using Agisoft. The Digital Elevation Model (DEMNAS) with 8.2 m resolution was used to compare the red, green and blue bands. The analysis used was Co-Kriging Geo Statistics Analysis, the compilation of algorithms based on the regression equation and ten index formulations. Validation was done by correlation continued with the regression or paired t-test if the parameter relationship was close. The available water measured in the field ranged from 5.16-48.28%. The results showed that the formulation of soil water content could be run on the Red, Green, and Blue bands, Intensity index, TGI index, ExGreen index and DEMNAS with a weak correlation (below 0.5), where TGI had the highest value (r=0.32). A test of t-pairing was not done because of a weak correlation. The highest estimation of pF 4.2 is DEMNAS (r=0.35), and pF 2.5 was on the TGI index (r=0.4).

Abstract

One of the main technological tasks facing mining engineers today is a reduction of the oversized fraction output. Currently, the efforts of scientists are aimed atdeveloping reliable grain-size composition predicting models for the extracting rock mass, as one of the initial factors for reducing economic losses throughout the technological cycle. However, many of the existing models do not consider the mutual influence of a number of factors, which explains the instability of the drilling and blasting performance indicators, their low efficiency and, as a result, an increased oversized fraction output. The model for grain-size composition predicting for mining enterprises will be interesting only if the proposed technological solution together with a pre-established fraction of rock mass will increase the efficiency of blasting operations with the desired reduction of all material and non-material expenditures. In this paper the authors give a brief overview of the global mining volumes; provides information on the extraction of key types of minerals, as well as revenues derived from their sale. They also specify the direction for future actions in creating a predicting model for the rock mass output of a certain fragmentation after the explosion.
