Abstract

Heavy metals (HM) are metals with high density and high electrical conductivity. It is an important part of the earth's crust and appears in our environment through natural (volcanoes, springs) and human activities (use of fossil fuels, agriculture and industry). The high sulfate and metal content in acid mine drainage causes significant environmental damage, requiring special treatment. Almost all industrial waste contains heavy metals. More industry will increase pollution of water sources due to industrial waste. The purpose of this research is as a reference in analyzing plant types that quickly absorb the heavy metals Lead (Pb) and Chromium (Cr) in water using the phytoremediation method. It is hoped that acid mine drainage management methods that are easy to use, cheap and environmentally friendly will be implemented for sustainable development. One of the rehabilitation techniques for AAT polluted environments is phytoremediation. Phytoremediation is the most effective method for managing acid mine drainage. The research results show that several plants are very effective and significant in helping the absorption of the heavy metals Lead (Pb) and Chromium (Cr) contained in acid mine drainage. The research results showed that water spinach (Ipomea Aquatic) 95.8% and water jasmine (Echinodorus Palaefolius) 92.5% were the most suitable plants for the phytoremediation method when controlling acid mine drainage.

Abstract

Biodiesel consists of various long-chain methyl ester fatty acids which can be produced from renewable sources, for example, oil from palm seed extract (Adonidia merrillii). This research aims to determine the yield of extracted oil and biodiesel from putri palm seed oil. This research is experimental research with a quantitative descriptive approach. The extraction process was carried out using a Soxhlet apparatus with n-hexane solvent. The extracted oil is then tested for its characteristics, esterified and transesterified to produce biodiesel. Based on the research conducted, it was found that the oil yield from extraction was 0.47% or quite low. However, the biodiesel yield from putri palm seed oil is quite high, namely 87.66%. This research produces biodiesel in gel form at room temperature. This biodiesel gel is the first and newest discovery in the field of renewable energy sources. Biodiesel gel can be used as fuel for portable cooking equipment and food heaters to keep buffet and catering dishes warm.

Abstract

Increased industrialization and urbanization lead to heavy metal pollution of waters, causing serious environmental impacts. Existing microbial technologies to address this problem are often expensive and not always environmentally friendly. Phytoremediation, using plants to remove heavy metals, offers a cheaper and environmentally friendly solution. These methods include phytoextraction, phytostabilization, phytovolatilization, phytofiltration, and phytodegradation. Phytoremediation technology can be applied in-situ or ex-situ, with in-situ methods being more economical. The plants compared in the literature review are Ipomoae aquatica Forks, Salvinia molesta, Pistia stratiotes, Eichhornia crassipes and Sagittaria lancifolia. Based on previous studies, research shows plants such as water hyacinth (Eichhornia crassipes) and spear leaves (Sagittaria lancifolia) are effective in absorbing copper (Cu) from polluted water, making them optimal choices for phytoremediation. This technology provides an efficient and low-cost solution to address heavy metal pollution.

Abstract

Economic development and anthropogenic activities, such as industry and agriculture, lead to deepening soil pollution by heavy metals. Heavy metal pollution threatens human health through the food chain, air and direct contact. Agricultural soils are often polluted by mining waste residues, pesticides, and sewage disposal, which require immediate attention. Heavy metals such as cadmium (Cd), which cannot be biodegraded, have high toxic potential and adversely affect plant health, growth and food production. Conventional remediation methods, such as physical and chemical, face challenges such as high costs and the risk of secondary pollution. As an alternative, phytoremediation offers an environmentally friendly and low-cost solution by using plants to accumulate and remove heavy metals. This method is effective in reducing Cd pollution in soil. The purpose of the literature review is to compare plants that have effectiveness in cadmium absorption in soil. Based on the review of previous studies, it shows that plants such as Impatiens balsamina L (96%) and Red Cockscomb Celosia plumosa (Voss) Burv (85%) are highly efficient in Cd sorption and suitable for phytoremediation applications. This phytoremediation technology offers an easy and effective way to deal with heavy metal pollution in soil.

Abstract

Air Asam Tambang (Acid Mine Drainage/AMD) merupakan masalah lingkungan yang signifikan akibat aktivitas pertambangan, yang menyebabkan pencemaran air permukaan dan tanah karena tingginya kandungan logam berat, terutama Besi (Fe) dan Mangan (Mn). Penelitian ini bertujuan untuk mengevaluasi berbagai metode pengolahan AMD berdasarkan tinjauan literatur, termasuk pendekatan fitoremediasi, kimia, dan fisika. Beberapa metode yang dianalisis meliputi Purun Tikus (Eleocharis dulcis), Kapur Tohor, Arang Aktif Tempurung Kelapa, dan Batu Tawas. Hasil penelitian menunjukkan bahwa metode Purun Tikus sangat efektif dalam menyerap Fe dan Mn (87,11–95,28%) dengan biaya rendah, tetapi membutuhkan waktu pemrosesan yang lebih lama (25 hari). Kapur Tohor secara efektif mengurangi logam berat hingga 94,71% dalam 7 hari, meskipun membutuhkan jumlah bahan yang cukup besar. Batu Tawas mencapai efektivitas 90% hanya dalam 2 hari, tetapi memerlukan jumlah bahan yang banyak. Sementara itu, Arang Aktif Tempurung Kelapa menunjukkan efisiensi paling rendah (33,33%) dalam menghilangkan Fe dan Mn, sehingga kurang disarankan untuk aplikasi skala besar. Pemilihan metode pengolahan AMD yang tepat harus mempertimbangkan faktor efektivitas, biaya, ketersediaan bahan, serta dampak lingkungan. Fitoremediasi dengan Purun Tikus merupakan pilihan yang ramah lingkungan dan berkelanjutan, meskipun kurang cocok untuk kebutuhan remediasi yang mendesak. Sebagai alternatif, kombinasi metode aktif dan pasif dapat memberikan pendekatan yang lebih efisien dan efektif dalam mengatasi pencemaran AMD di berbagai kondisi pertambangan. Dengan mengintegrasikan berbagai strategi pengolahan, solusi yang lebih komprehensif dan berkelanjutan terhadap polusi AMD dapat dicapai.

Abstract

This study aims to analyze the stability of various glycine conformations using a quantum computational approach based on molecular mechanics. The methodology involves geometry optimization performed on computational servers, where each conformation is analyzed to obtain the Final Single Point Energy, Loewdin charges, dipole moments, and the energy gap between the Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO). Optimization results reveal stability differences among glycine conformations based on single-point energy values, with Loewdin charge values indicating varied electron distribution across each conformation. The most optimal energy obtained was -284.080 Hartree for the conformation in which the amino group aligns with the carbonyl group. Dipole moment analysis provides insights into conformation polarity, where differences in glycine conformations significantly impact the overall dipole moment. The conformation with the highest polarity features the amino group adjacent to the hydroxyl group, with a dipole moment of 5.58246 Debye. Additionally, the HOMO-LUMO energy gap for each conformation correlates with glycine’s stability and chemical reactivity. This study offers insights into factors influencing glycine stability, such as steric and electronic effects, and aims to support further research on glycine development.
