Abstract

The use of Agrochemicals for increasing the agricultural products are commonly applied on agricultural soils, especially the soil used for cultivatif cabbage in the area of Kintamani-Bangli, Province of Bali. Agricultural soils used for cultivatif cabbage in Kintamani area commonly apply inorganic fertilizers and synthetic pesticides for increasing the products. However the use of these agrochemicals tends to uncontrol and causes the soils polluted. One factor of contamination of soil is the presence of heavy metals in the soil. Intensive use of inorganic fertilizers and synthetic pesticides can lead to high levels of bioavailability of heavy metals in plants. This study intend to determine the total contents of heavy metals Pb and Cd in the agricultural soils and analyse bioavilability of those metals. The total metals was determined by the use of digestion method involving reverse aquaregia (HNO3:HCl, 3:1) and the bioavailability of the metals was determined by applying single extraction including HCl and EDTA extractions. The results show that the total contents of Pb and Cd in the soils were 4,1261 ± 0,1113 – 14,5923 ± 0,3790 mg/kg and 0,8803 ± 0,0259 - 0,9425 ± 0,0195 mg/kg respectively. The bioavailable metals of Pb and Cd in the soils was 31,14% - 42,53% and 78,70% - 80,73%, respectively.

Abstract

Industri tekstil merupakan salah satu penghasil limbah cair yang banyak mengandung berbagai zat warna sintetik yang sulit untuk terurai seperti metilen biru (MB). Sekitar 15-20% produk zat warna MB yang tidak dapat terpakai kembali akan masuk ke dalam air buangan pabrik yang pada akhirnya mengalir ke lingkungan perairan. Hal tersebut menimbulkan berbagai macam dampak buruk terhadap lingkungan, khususnya di lingkungan perairan. Untuk menanggulangi masalah tersebut dapat dilakukan dengan upaya mendekomposisi zat warna tersebut menggunakan sinar UV dan mempercepat proses dekomposisi dengan bantuan fotokatalis, yaitu nanopartikel perak. Tujuan dari penelitian ini untuk mengetahui kondisi optimum dan keefektifan kondisi tersebut dalam mendegradasi zat warna MB. Kondisi optimum yang diukur meliputi volume fotokatalis/NPAg, waktu irradiasi, dan pH. Kondisi optimum tersebut digunakan untuk menentukan efektivitas dari metode yang digunakan. Hasil menunjukkan kondisi optimum proses fotodegradasi MB yaitu volume fotokatalis/NPAg sebanyak 10 mL, waktu iradiasi 60 menit dengan pH-4 yang efektif mendegradasi zat warna MB 100 ppm sebanyak 98,21%. Metode yang digunakan juga efektif pada konsentrasi MB hingga sebesar 150 ppm karena mampu mendegradasi hampir 100%. Kata kunci: fotodegradasi, fotokatalis, NPAg, metilen biru, plumeria rubra. ABSTRACT The textile industry is one of the producers of liquid waste that contains many synthetic dyes and difficult to decompose such as methylene blue (MB). Approximately 15-20% of the MB products that cannot be reused will go into the wastewater which eventually be drained into the catchment waters. This causes a variety of negative impacts, especially in the water environment. One way to prevent this problem is by decomposing the dye using UV light and accelerating the decomposition process with the photocatalysts, namely silver nanoparticles. The purpose of this study is to determine the optimal conditions for the photodegradation process of MB dyes, and the effectiveness of the degradation of MB dye under optimal conditions. The search was conducted by firstly finding the optimal conditions of the photocatalyst / NPAg volume, irradiation time, and pH. The optimal condition was then applied to photodegrade various concentrations of MB to determine the effectiveness of the process. The results showed the optimal condition of MB photodegradation was 10 mL of photocatalyst / NPAg, 60 minute irradiation time at pH 4. Under such condition, the method effectively degraded 98.21% of100 ppm MB. The method used is also effective for MB up to 150 ppm because it is able to degrade almost 100%. Keywords: photocatalyst, photodegradation, NPAg, methylene blue, plumeria rubra.

Abstract

Timbal (Pb) merupakan pencemar yang umum dijumpai dalam tanah pertanian dan bahkan sering mengkontaminasi tanaman yang tumbuh pada tanah tersebut. Salah satu cara untuk menurunkan kandungan cemaran logam berat seperti Pb dalam tanah pertanian adalah fitoremediasi. Tujuan penelitian ini adalah menurunkan kandungan cemaran Pb dalam tanah pertanian. Metode yang digunakan adalah remediasi dengan menanam pohon gumitir (Tagetes erecta L.) pada tanah pertanian yang diberi perlakuan penambahan berbagai konsentrasi Pb2+. Hasil penelitian menunjukkan bahwa sebelum ditanami gumitir, tanah A, B, C yang ditambahkan Pb masing-masing sebanyak 100; 200; dan 400 mg/kg, memilliki konsentrasi berturut-turut sebesar 108,97±2,25; 214,18±5,47; dan 447,04±4,89 mg/kg, sedangkan pada saat panen konsentrasinya berturut-turut sebesar 100,52±1,66; 170,04±2,88; dan 397,98±2,24 mg/kg. Bagian tanaman yang paling tinggi menyerap Pb adalah bagian akar yaitu sebesar 47,01±4,52 mg/Kg. Efektivitas penyerapan logam Pb dalam tanaman gumitir pada tanah A, B, dan C adalah <50% dengan nilai TF dan BCF < 1, sehingga mekanisme dalam mengakumulasi logam timbal kurang efektif atau disebut fitostabilisasi. Kata kunci: efektivitas penyerapan, remediasi, Tagetes erecta L., timbal. ABSTRACT Lead (Pb) is a common pollutant found in agricultural soils and often contaminates the plants growing on the soil. One way to reduce the content of heavy metal contamination such as Pb in agricultural soil is through phytoremediation. The purpose of this study was to reduce the content of Pb in agricultural soils. The method used was remediation by planting gumitir (Tagetes erecta L.) plants on the soil added with various concentrations of Pb2+. The results showed that before planting with gumitir, the soil A, B, C added with Pb of 100; 200; and 400 mg Pb/kg soil, respectively, having the concentration of 108,97±2,25; 214,18±5,47; and 447,04±4.89 mg/kg, respectively, while on the harvesting time the concentration of Pb was 100,52±1,66; 170,04±2,88; and 397,98±2,24 mg/kg, respectively. The part of the plant that absorbed the highest Pb was the root, which was 47,01±4,52 mg/kg. The effectiveness of Pb absorption by gumitir plants in A, B, and C soils were <50% with TF and BCF values ??< 1, so the mechanism in accumulating lead metal is less effective or called phytostabilization. Keywords: adsorption, effectiveness, lead, remediation, Tagetes erecta L.

Abstract

ABSTRAK Limbah yang dihasilkan dari industri tekstil berupa limbah cair yang keruh, berwarna dan sulit dihilangkan sehingga dapat mengganggu ekosistem perairan. Limbah hasil pencelupan dapat mencemari lingkungan karena menggunakan zat warna azo yang sulit untuk didegradasi. Salah satu metode yang dapat diaplikasikan untuk mengatasi ini adalah fotodegradasi. Dalam artikel ini dilaporkan sintesis fotokatalis bentonite-ZnO dan aplikasinya dalam fotodegradasi zat warna dalam limbah pencelupan. Karakterisasi fotokatalis dilakukan dengan melihat kristalinitas kompositnya menggunakan X-Ray Diffraction (XRD), luas permukaannya dengan metode methylene blue serta penentuan efektivitas degradasi dengan dan tanpa sinar. Difraktogram yang dihasilkan menunjukkan beberapa puncak dengan intensitas tinggi: pada 2? = 20,51° (d=4,32Å) yang menunjukkan adanya mineral kuarsa sedangkan pada 2? = 26,28° (d=3,39Å) mengindikasikan illit. Puncak khas dari ZnO ditunjukkan pada pola difraksi 2? = 36,18° (d=2,46Å) dan 2? = 59,64° (d=1,54Å). Luas permukaan bentonit dan bentonit-ZnO berturut-turut 183,0665 dan 180,2460 m2/g. Kondisi optimum yang diperoleh dalam mendegradasi zat warna limbah industri pencelupan yaitu massa 100 mg pada pH 2 dan waktu irradiasi atau pengadukan dalam gelap selama 45 menit. Degradasi dengan sinar lebih efektif (95,66 ± 0,16%) dibandingkan tanpa sinar (73,28 ± 0,55%) yang menunjukkan peran komposit bentonite-ZnO sebagai fotokatalis. Kata kunci: Bentonit-ZnO, Fotodegradasi, Limbah Industri Pencelupan ABSTRACT Liquid waste generated by the textile industry is typically murky, intensely coloured, and hard to treat. As a consequence, it can pollute the aquatic ecosystem. One potential method to overcome this problem is photodegradation to break the dye molecules down. In this paper the synthesis of bentonite-ZnO composite and its application as a photocatalyst are reported. The composite was prepared by sonicating a mixture of zinc acetate and bentonite. The characterization of the composite was conducted using X-Ray Diffraction (XRD) and methylene blue method to determine its surface area, and its degradation capacity as photocatalyst to degrade the dye waste. The diffractogram reveals several peaks with high intensity, i.e. at 2? = 20,51° (d = 4,32Å) indicating mineral quartz, and at 2? = 26,28° (d = 3,39Å) showing Illite. The identifying peaks of the ZnO are in the diffraction pattern of 2? of 36,18° (d = 2,46Å) and 59,64° (d = 1,54Å). The surface area of the bentonite and bentonite-ZnO are 183,0665 and 180,260 m2/g respectively. The optimum conditions obtained for the dye degradation are 100 mg photocatalyst at pH 2 and irradiation time of 45 minutes. Degradation under UV light is more effective with a degradation percentage of 95,66 ± 0,16% than that in the dark, which is 73,28 ± 0,55%. This shows that the composite plays its role as a photocatalyst for the degradation. Keywords: Bentonite-ZnO, Dyeing Industrial Waste, Photodegradation.

Abstract

The utilization of methylene blue dye in the textile industry can have a significant environmental impact due to its high toxicity. To address this issue, a study was conducted on the photodegradation of methylene blue dye using silver nanoparticles (AgNP) synthesized with marigold (Tagetes erecta) flower extract as a bioreducer. This article reports on the synthesis of AgNP and its application in the photodegradation of methylene blue dye. The synthesis of AgNP involved the reduction of AgNO3 with marigold flower extract. Different ratios of marigold flower extract to AgNO3 solution (0.01 M) were used: 1:9, 2:8, 3:7, 4:6, and 5:5. The formation of AgNP was monitored at various time intervals using UV-Vis spectroscopy. The best AgNP sample was measured using a Particle Size Analyzer (PSA). The research results indicated that the optimal conditions were achieved at a marigold extract to AgNO3 ratio of 2:8, with the UV-Vis spectrum showing a peak at a wavelength of 411 nm. The optimum conditions for photodegradation were as follows: AgNP volume of 15 mL, irradiation for 30 minutes, and pH 4. Under these conditions, photodegradation of methylene blue dye achieved a reduction of up to 72.46% from the initial concentration of 100 ppm.

Abstract

ABSTRAK : Identifikasi merah K3 dalam sediaan perona mata secara LC-MS/MS dilakukan untuk mengkonfirmasi keberadaannya yang sering kali ditemukan dalam konsentrasi kecil. Metode spektrofotometeri UV-VIS dan HPLC tidak cukup untuk mengkonfirmasi keberadaan merah K3 yang dinyatakan positif dengan metode KLT. Optimasi metode dilakukan pada kondisi spektrometer massa dan sistem kromatografi cair yang berlaku pada LC-MS/MS sebelum dilakukan proses identifikasi. Hasil optimasi menunjukkan identifikasi merah K3 dengan LC-MS/MS menggunakan teknik ionisasi elektrospray (ESI) dan sistem Multiple Reaction Monitoring (MRM) pada mode ionisasi negatif. Ion prekursor pada m/z 375 dan ion produk pada m/z 204, 80, 140 digunakan untuk identifikasi. ABSTRACT : Identification of red dye (CI 15585) using LC-MS/MS in eye shadow was performed to confirm its presence in very low concentrations. The UV-VIS spectrophotometry and HPLC are not sufficient to confirm the presence of red dye identified by the TLC. The optimation of the method was carried out under the condition applicable to LC-MS / MS prior to identification process. Optimation results show that red dye can be identified with LC-MS/MS using electrospray ionization technique (ESI) and Multiple Reaction Monitoring (MRM) system under negative ionization mode. The precursor ion at m / z 375 and the product ions at m / z 204, 80, 140 are used for identification.
