Abstract

This study aimed to analyze the adsorption pattern of heavy metals. Adsorption tests were conducted on Fe and Mn in Acid Mine Drainage (AAT) samples containing Fe 13.006 mg/L and Mn 30.590 mg/L at various time and adsorbent mass variations. The experimental results showed that the composite mass of 5 grams could reduce the iron concentration to 99.35%, but the adsorbent mass of 2.5 grams is more efficient because it succeeded in reducing the iron concentration to 0.1484 mg/L within 30 minutes, thus meeting the quality standards set. The adsorption pattern in this study is described through the adsorption isotherm curve which has a correlation coefficient (R2) close to 1. Based on the analysis results, Fe adsorption followed the Langmuir isotherm pattern with R2 = 0.998, while Mn adsorption followed the Langmuir isotherm pattern with R2 = 0.997. The analysis showed that the correlation coefficient in Langmuir isotherm was higher than Freundlich isotherm for both Fe and Mn, indicating a very strong level of correlation in the Langmuir model. The adsorption mechanism observed in this study is characterized as chemical adsorption. The adsorbent exhibits an adsorption capacity of 1.286 mg/g for Fe and 1.031 mg/g for Mn under the optimal conditions of a 2.5-gram mass of adsorbent for 30 minutes.

Abstract

PT. Bhumi Sriwijaya Perdana Coal, a coal mining company located in Musi Banyuasin District, South Sumatra, utilizes Caterpillar 330D2L excavators and Mitsubishi Fuso 220PS dump trucks for coal extraction activities. The company set a production target of 52,612 tons/month for March 2023. However, actual production fell short, with the hauling equipment achieving only 41,260.08 tons/month, despite the loading equipment exceeding the target with 59,086.93 tons/month. This research aims to identify factors hindering the achievement of production targets and propose strategies for improvement. The analysis revealed that the mismatch between the loader and hauler operations, reflected by a low match factor of 0.57, was a significant contributor to inefficiencies. Additional challenges included extended cycle times influenced by front-loading patterns, hauling path conditions, and equipment synchronization. After implementing improvements, including cycle time optimization and increased loading flow, the productivity of the Mitsubishi Fuso 220PS dump trucks increased to 59,732.67 tons/month. The match factor between the Caterpillar 330D2L and the Mitsubishi Fuso 220PS improved to 0.83, demonstrating enhanced operational alignment. These findings highlight the importance of addressing cycle times, optimizing equipment compatibility, and improving workflows to meet production targets effectively.

Abstract

Adsorption is one alternative to acid mine drainage (AMD) management, particularly for reducing heavy metal concentrations. Adsorption is still performed manually at this time. In this study, the adsorption procedure is automated and controlled via Arduino rather than being performed manually. The efficacy of using an Arduino in the adsorption of AMD at a pH of 2.6 and an Fe initial concentration of 42.807 mg/L was assessed by modifying the adsorption time parameters. The results showed that the assembled instrument was able to reduce the Fe concentration to meet the quality standards in just 2 minutes. The effectiveness of Fe adsorption reached 96.79% with a final concentration of 1.3724 mg/L. Fe adsorption capacity reached 0.0414 mg/g in the second minute. The Fe adsorption process in this study is chemical adsorption.

Abstract

Artikel review ini bertujuan untuk membahas dampak sosial, ekonomi, dan lingkungan dari penambangan emas skala kecil di Kulon Progo. Penambangan emas skala kecil telah menjadi sumber pendapatan utama bagi banyak orang di Kulon Progo, tetapi juga membawa dampak negatif yang signifikan. Secara sosial, penambangan emas skala kecil telah menyebabkan konflik dan ketegangan antara masyarakat lokal dan para penambang pendatang, serta penurunan partisipasi dan solidaritas sosial. Secara ekonomi, penambangan emas skala kecil telah menyebabkan pergeseran struktur ekonomi daerah, di mana pertanian tidak lagi menjadi sumber pendapatan utama. Namun, manfaat dari penambangan emas seringkali bersifat jangka pendek dan tidak berkelanjutan, menyebabkan ketidakstabilan ekonomi. Secara lingkungan, penambangan emas skala kecil telah menyebabkan degradasi tanah yang signifikan, polusi sumber air, pencemaran tanah, sedimentasi sungai, dan perubahan tata guna lahan. Keberlanjutan dari pilot plant pirometalurgi perlu dipertimbangkan sebagai upaya untuk pengurangan merkuri dalam penambangan emas skala kecil.

Abstract

Air asam tambang (AAT) merupakan limbah berbahaya yang mengandung logam berat seperti besi (Fe), mangan (Mn), tembaga (Cu), kadmium (Cd), dan merkuri (Hg), yang berpotensi mencemari lingkungan serta membahayakan kesehatan manusia. Kajian literatur ini bertujuan untuk mengevaluasi potensi karbon aktif berbasis material lokal dalam mengadsorpsi logam berat dari AAT melalui kajian terhadap sebelas artikel ilmiah terkini. Sumber karbon aktif yang digunakan meliputi limbah pertanian, biomassa, dan batubara lokal, yang telah melalui proses aktivasi fisik, kimia, atau kombinasi keduanya. Hasil kajian menunjukkan bahwa karbon aktif dari material lokal mampu menurunkan konsentrasi logam berat dengan efisiensi bervariasi, mencapai hingga 99,93%. Ukuran partikel dan metode aktivasi berpengaruh signifikan terhadap kapasitas adsorpsi, di mana ukuran partikel lebih kecil dan penggunaan aktivasi kimia atau kombinasi meningkatkan luas permukaan serta porositas karbon aktif

Abstract

This study investigates the effect of seawater moisture content on the resistivity of unconsolidated sand in the coastal region of Yogyakarta. Laboratory experiments were conducted using a standard ASTM G-57 soil box with samples prepared at varying percentages of seawater moisture content. The results indicate that increasing seawater content in the sediment medium leads to an exponential decrease in resistivity. A mathematical relationship was established in the form of a power function: R=1145.7MC?2.23. Resistivity values tend to stabilize when the moisture content exceeds 13%. A resistivity range of 0.8–2.8 ??m is proposed as a cut-off for identifying seawater intrusion in coastal areas. These findings provide an important contribution to the development of geoelectrical methods for monitoring seawater intrusion and evaluating groundwater quality in coastal regions, which can serve as a basis for sustainable water resource management.

Abstract

This research aims to analyze the effect of the adsorption process on the morphology of adsorbents consisting of a mixture of claystone, zeolite, and activated coconut shell charcoal in adsorbing Fe ions from acid mine drainage. The adsorption process was carried out in a batch system using a hotplate stirrer on a laboratory scale. The experimental method was applied to evaluate the characterization of the adsorbent surface morphology before and after the adsorption process using a Scanning Electron Microscope (SEM). The research results showed significant changes in the adsorbent surface morphology after the adsorption process, indicated by differences in the structure and topography of the adsorbent.

Abstract

Terdapat kadar batugamping yang tinggi dan rendah yang berada di Kuari penambangan batugamping di PT Indocement Tunggal Prakarsa. Oleh karena itu untuk mendapatkan kualitas bahan baku yang baik, maka perlu dilakukan analisis geokimia dengan metode Geokimia berupa analisis X-Ray Diffraction (XRD) dan X- Ray Fluorescence (XRF) untuk mengetahui kadar unsur yang terkandung dalam batugamping dengan tujuan untuk mengetahui hasil kadar yang dimiliki tiap sampel batugamping yang akan digunakan untuk pembuatan semen. Berdasarkan penelitian dan analisis data yang dilakukan diperoleh kesimpulan litologi batuan yang terdapat pada sampel 1 sampai 15 memiliki litologi batuan yang berbeda yakni sampel sampel 1,6,9,10 litologi batuan mudstone, sampel 2,3,11,13 litologi batuan Packestone, sampel 5,12,14,15 dengan litologi batuan wackestone, dan litologi batuan Boundstone sampel 4,7,8. Kadar batugamping pada sampel 9 dan 1 memiliki kadar CaO, SiO₂, dan Al₂O₃ yang rendah, maka dari itu direkomendasikan blending batugamping yang memenuhi standar kadar yang ditentukan, dimana pada kadar CaO 29.93% dilakukan blending antara sampel batuan pada sampel 9 dan 14 setelah diblending memperoleh hasil 62.75%. Kadar CaO 47.45% dilakukan blending pada sampel 1 dan 14 setelah diblending memperoleh hasil 64.51%.
