Abstract

Law No. 3 of 2020 on Mineral and Coal Mining states that reclamation is an activity that must be carried out during mining operations in order to repair, restore and improve the quality of the environment and ecosystems so that they can function again according to their mission. Phytoremediation can serve as an alternative solution in reclamation activities that is cost effective, efficient and environmentally friendly. This research aims to determine the efficiency of nickel reduction using Sengon (Paraserianthes falcataria), while calculating and analysing the financial requirements and risk management involved. Nickel post-mining soil was placed in 25x25 cm polybags and four-month-old Sengon was planted. The plants were maintained with fertiliser and humic substances and watered daily. Nickel levels in the soil were measured using atomic absorption spectrophotometry (AAS). The results showed that reactor H0P0 (100% post-mining soil) successfully removed 72.5% of the nickel.

Abstract

Saat ini, produksi tahu masih berkembang pada industri skala rumahan. Akibatnya, sebagian besar produsen belum memiliki Instalasi Pengolahan Limbah (IPAL) sehingga air limbah tahu langsung dibuang ke badan air. Padahal limbah cair tahu mengandung konsentrasi COD yang tinggi dan melebihi baku mutu sehingga menyebabkan pencemaran tanah dan air. Oleh karena itu, diperlukan alternatif untuk menangani permasalahan pencemaran limbah cair tahu yang murah, cepat, dan ramah lingkungan dengan fitotreatment subsurface flow constructed wetland menggunakan tumbuhan Limnocharis flava L.Penelitian pendahuluan dilakukan untuk menguji karakteristik awal air limbah dengan parameter utama COD dan parameter pendukung pH dan temperatur. Penelitian dilanjutkan dengan propagasi, aklimatisasi, dan Range finding test (RFT). Setelah itu, dilakukan penelitian utama selama 21 hari subsurface flow constructed wetland (SSF CW) aliran vertikal dan pemberian pupuk NPK. Nilai konsentrasi limbah cair tahu yang dapat diterima Limnocharis flava L. saat Range Finding Test (RFT) adalah 20%. Konsentrasi akhir dan efisiensi removal COD dengan dan tanpa pupuk NPK aliran vertikal SSF adalah 152 mg/L dan 136 mg/L; 80% dan 83,4%. Nilai pH dengan dan tanpa pupuk NPK aliran vertikal SSF adalah 7 dan 7,1.

Abstract

Pencemaran air tanah oleh logam berat timbal (Pb) berdampak buruk bagi kesehatan manusia dan lingkungan. Logam berat Pb merupakan salah satu polutan yang disoroti karena bersifat toksik, persisten, dan bioakumulatif. Berbagai metode telah dikembangkan untuk remediasi air tanah tercemar Pb, tetapi sebagian besar memakan biaya yang mahal dan memerlukan waktu yang lama. Sebagai alternatif, teknologi Permeable Reactive Barrier (PRB) menawarkan pendekatan pasif in-situ yang efisien untuk mengurangi kadar logam berat dalam air. Implementasi PRB sudah beberapa kali digunakan dalam mereduksi berbagai kontaminan seperti Cr, Zn, Cu, Pb dan As. Hingga saat ini PRB terus dikembangkan untuk meningkatkan efektivitasnya dalam remediasi air tanah. Penelitian ini bertujuan mengevaluasi efektivitas PRB berbahan biochar tempurung kelapa dengan perekat semen dalam meremediasi air tanah berkadar Pb 100 mg/L dengan memvariasikan ketebalan (2 cm dan 4 cm). Reaktor beraliran vertikal dioperasikan selama 24 jam untuk mengamati performa penyisihan. Hasil menunjukkan bahwa PRB dengan ketebalan 2 cm menghasilkan efisiensi penyisihan tertinggi, yakni 99,9% dalam waktu detensi 6 jam, melalui mekanisme adsorpsi, presipitasi, dan interaksi ionik. Presipitasi Pb(OH)2 berperan penting pada pH basa yang dihasilkan oleh hidrasi semen, meskipun kondisi ini memerlukan pengaturan pH efluen sebelum dilepas ke lingkungan. Temuan ini memberikan dasar ilmiah untuk pengembangan PRB berbasis biochar-semen secara lebih luas, termasuk optimasi media, pengujian skala lapangan, dan penerapan pada sistem pengolahan air tercemar lainnya.

Abstract

Research on Chlorella vulgaris is vital due to its rapid growth and versatile habitat adaptability. C. vulgaris is a fast-growing green microalga used for phycoremediation of heavy metals such as mercury which is usually found in gold mining wastewater. This research aims to determine the best mercury removal efficiency with variations in aeration rate, medium concentration, and C. vulgaris inoculum concentration. This research was conducted by cultivating C. vulgaris and examining its response to various parameters in an artificial mercury (II) chloride (HgCl2) solution. Moreover, other parameters such as cell density, pH, temperature, bicarbonate, and dissolved oxygen were monitored over a seven-day experimental period. The highest removal efficiency (61.34%) at a mercury concentration of 0.3 mg/L was found in the variant with a walne medium dose of 1 mL/L, inoculum concentration of 10%, and aeration rate of 3 L/min. This study confirmed the potential of C. vulgaris as an effective agent for heavy metal removal, particularly mercury, and contributed to bioremediation.

Abstract

Pengelolaan IPAL merupakan komponen penting dalam menjaga kualitas lingkungan dan kesehatan masyarakat, terutama di lingkungan padat penduduk dan meningkatnya pembangunan hunian vertikal di Jakarta Timur dengan jumlah penduduk terbanyak di Jakarta berdasarkan data BPS 2023. Apartemen merupakan hunian yang menghasilkan air limbah setiap harinya berpotensi mencemari lingkungan jika tidak dikelola dengan baik, berdasarkan pada kondisi eksisting yang ada di lapangan, didapati masih adanya apartemen yang belum mengelola IPAL dengan baik seperti tidak beroperasinya IPAL secara optimal. Aspek teknis dan aspek Sumber Daya Manusia (SDM) sangat berperan dalam pengelolaan IPAL di Apartemen dalam mengoperasikan dan memelihara sistem IPAL. Penelitian ini bertujuan untuk mengevaluasi pengelolaan IPAL Apartemen ditinjau dari aspek teknis dan SDM dengan studi kasus empat apartemen di Jakarta Timur. Metode yang digunakan adalah pengambilan sampel air limbah domestik di empat apartemen dengan kategori low rise, medium rise, dan high rise kemudian dibandingkan dengan standar yang ditetapkan dalam Permen LHK No. 68 Tahun 2016. Kemudian dilakukan evaluasi teknis berdasarkan kapasitas, baku mutu, dan efisiensi penyisihan. Analisis SDM dilakukan secara deskriptif untuk menilai kompetensi serta kebiasaan penghuni dalam pengelolaan lingkungan. Hasil penelitian menunjukkan bahwa apartemen dengan kategori low rise dan high rise telah memenuhi baku mutu, kapasitas, dan efisiensi penyisihan yang diharapkan. Dari aspek SDM, manajemen dan operator di apartemen-apartemen tersebut memiliki kompetensi dalam pengelolaan IPAL, sedangkan pada apartemen kategori medium rise masih belum memenuhi baku mutu dan efisiensi penyisihan yang diharapkan hal ini disebabkan karena unit IPAL yang mengalami kerusakan pada blower dan tidak tersedianya operator yang memiliki sertifikat kompetensi dalam mengoperasikan IPAL.

Abstract

The concept of productive green space has been mentioned in Al-Qur’an, which was revealed several centuries ago. However, Productive Facade (PF), a Vertical Greening System (VGS) method, has only recently been seen as a viable solution to provide crops and a cooler atmosphere in densely populated residential areas. The purpose of this article is to examine, from both scientific and Islamic perspectives, how shading and CO2 concentration reduction from PF can help cool the outdoor air, as well as the implications of this cooling mechanism for the development of a PF system as a secondary building skin that is more responsive to increasing urban temperatures. Literature reviews and experimental studies have been conducted to provide evidence and arguments from both scientific knowledge and Islamic perspectives. It was found that PF was able to provide an outdoor cooling effect. In addition, plant shade and CO2 uptake in PF are strongly correlated with air temperature. These findings are mentioned in the Qur'an and Hadiths as a basis for constructing an Islamic perspective.

Abstract

The widespread use of mercury (Hg) in artisanal and small-scale gold mining (ASGM) necessitates effective bioremediation strategies. This study evaluated the mercury reduction capabilities of two bacterial strains, Bacillus subtilis and Pseudomonas aeruginosa, using real-world ASGM liquid waste. In a seven-day laboratory-scale experiment, we assessed the performance of single and mixed bacterial cultures under varying pH conditions. Our results show that B. subtilis was particularly effective, achieving a maximum Hg2+ removal efficiency of 90.07%. Critically, while the cell viability of single cultures declined significantly over the study period, mixed cultures maintained superior population stability, reaching 7.4 log CFU/mL on day 7, especially under alkaline conditions. This stability suggests a beneficial synergistic relationship between the two species. The enhanced long-term viability and robust detoxification mechanisms observed in the mixed culture system underscore the high potential of this approach for developing sustainable bioremediation solutions for the ASGM sector.

Abstract

Copper contamination from anthropogenic activities negatively impacts water quality and agriculture, with documented cases showing reduced crop yields and economic losses. This study conducted a preliminary screening to evaluate the survivability and toxicity signs of V. zizanioides under copper exposure as an initial assessment of its potential for phytoremediation. A range finding test was performed using five Cu concentration (100, 250, 500, 750, 1000 mg/L) and control. Following 40 days-propagation period, plants were exposed to Cu  for 7-14 days. Daily observations included plant condition and height, while pH and temperature were periodically monitored to ensure that plant mortality resulted from toxicity rather than environmental factors. The results indicated that V. zizanioides tolerated copper concentration up to 100 mg/L. However at concentrations above 100 mg/L, typical toxicity symptoms, such as chlorosis and necrosis, appeared as early as the second day. Complete plant mortality was observed at the highest concentration, 1000 mg/L. Although this study did not assess metal removal performance, these findings highlight the resilience of V. zizanioides under copper stress and provide an important basis for future research to determine its suitability for phytoremediation or constructed wetlands.
