Abstract

Kemiri Sunan (Reutealis trisperma (Blanco) Airy Shaw) merupakan tanaman penghasil minyak non pangan yang dapat digunakan sebagai agen fitoremediasi. Penelitian bertujuan untuk mengetahui respon pertumbuhan, anatomi, dan akumulasi Pb Kemiri Sunan yang diinokulasi jamur Dark Septate Endophyte (DSE) terhadap tailing tambang emas. Bibit berumur dua bulan yang telah diinokulasi jamur DSE 0,5% dipindahkan ke dalam pot berisi tailing tambang emas dengan konsentrasi berbeda dan ditanam selama 7 minggu. Parameter yang diamati meliputi tinggi tanaman, berat kering pucuk dan akar, luas permukaan daun dan anatomi jaringan. Analisis histokimia dilakukan untuk mengamati Pb dalam jaringan. Hasil penelitian menunjukkan bahwa konsentrasi tailing berpengaruh nyata terhadap tinggi tanaman dan parameter anatomi, tetapi tidak mempengaruhi berat kering tajuk dan akar maupun luas permukaan daun. Inokulasi DSE tidak berpengaruh nyata terhadap tinggi tanaman, berat kering pucuk dan akar, luas daun, dan parameter anatomi. Pada akar, akumulasi timbal diamati pada sel epidermis, korteks, berkas pembuluh, dan empulur akar, sedangkan pada daun diamati pada sel epidermis atas dan bawah, daerah antara xilem, dan jaringan parenkim. Inokulasi jamur DSE meningkatkan pertumbuhan dan menurunkan toksisitas Pb pada Kemiri Sunan.

Abstract

This research constitutes a qualitative descriptive analysis using Roland Barthes' semiotic theory, focusing on the concepts of denotation and connotation. Centered around the Instagram account @laviaminora, the study describes and analyzes messages of resistance against patriarchal hegemony manifested in visual texts. Employing semiotic analysis methods, this research highlights how signs of sexuality in the account serve as a form of critique against sexual repression and societal norms in Indonesia.Research findings indicate that the sexuality represented in @laviaminora is not merely a denotation of reality but also carries connotations that create subjective and emotional meanings. The account successfully constructs a narrative of resistance against longstanding myths related to patriarchal culture, emphasizing the values of women's freedom. In the context of Indonesian patriarchal society, the socio-cultural construction of sexuality is identified as a tool to maintain male dominance over women.The research concludes that @laviaminora creatively utilizes semiotics as a means to critique and resist patriarchal norms that continue to influence social and cultural life in Indonesia.

Abstract

Indonesia, as the world's largest nickel producer, has vast ultramafic areas that have the potential to become habitats for nickel hyperaccumulator plants (Ni). This study aimed to explore and analyze nickel hyperaccumulator plants in the mining area of CV. Unaaha Bakti Persada, North Konawe Regency, Southeast Sulawesi, Indonesia. The research was conducted from June to November 2023 using the exploration method at three observation stations, each consisting of three plots. The research stages carried out include exploration, plant collection and identification, and analysis of Ni content in soil as well as plant tissue using Atomic Absorption Spectrophotometry (AAS). A total of 32 plant species were found, which was dominated by Pteridium aquilinum ferns at Stations I and III and Scleria lithosperma grasses at Station II. The Ni content of the soil was very high (5,458.32–5,938.41 mg/kg) and far above the normal threshold. Several species showed high Ni accumulation capacity, with the most of six were Sarcotheca celebica, Knema metanensis, Pluchea carolinensis, Gymnostoma sumatrana, and Justicia gendarussa. The post mining sites were categorized as marginal due to heavy metal toxicity (Ni, Co, Cr), and therefore, only tolerant plants can survive. Sarcotheca celebica had the highest BCF value (0.1421) and was classified as a moderate accumulator. All the six species has the potential to be used for phytoremediation, phytomining and reclamation of post mining areas in Southeast Sulawesi.

Abstract

Acid mine drainage (AMD) is one of the most serious environmental impacts of mining, characterized by low pH and high metal content. This study aimed to evaluate the neutralization efficiency of waste-based granules made from fly ash, bottom ash (FABA), and goat manure for AMD treatment under laboratory conditions. Two types of granules were produced: (i) 45% fly ash, 45% bottom ash, and 10% cement; and (ii) 45% fly ash, 30% bottom ash, 15% goat manure, and 10% cement. Each type was applied at different volumes (10%, 30%, and 50%) and positions (bottom and suspended) for 48 hours. Results showed that granule type, volume, and placement significantly influenced pH neutralization and metal removal. The best performance was achieved by the suspended granule without manure at 50%, raising AMD pH from 2.45 to 9.17 within 3 hours, with 88.7% Fe and 66.5% Mn removal. XRD and Micro-XRF analyses confirmed that neutralization occurred through dissolution of Ca-based minerals and formation of calcite and gypsum. The study demonstrates that FABA granules offer a low-cost, sustainable option for AMD treatment and can serve as a contextual learning model in environmental and chemistry education, linking waste utilization with real-world applications of acid-base reactions and environmental sustainability.
