Abstract

PLTSa dan TPS merupakan bagian solusi dari penyelesaian permasalahan sampah plastik di Indonesia. Namun kegiatan yang dilakukan berdampak sebaliknya, karena solusi tersebut menyebabkan pencemaran baru. Pencemaran dihasilkan seperti menghasilkan gas-gas berbahaya dan emisi SOx dan NOX, serta residu lainnya dan dimungkinan juga terdapat mikroplastik. Tujuan dari penelitian ini ialah untuk mengidentifikasi mikroplastik pada false solution technology dan sebagai base data awal untuk pencegahan cemaran yang diakibatkan false solution technology. Metode penetukan lokasi yang digunakan adalah Purposive Random Sampling. Sampel diambil di 4 tempat titik lokasi pengambilan sampel, kemudian sampel diidentifikasi menggunakan mikroskop sterero dengan perbesaran 1,5x. Hasil menunjukkan seluruh sampel positif mengandung mikroplastik. Jumlah mikroplastik yang teridentifikasi di insenerator lakardowo yaitu 10 partikel/m³, TPS Bambe yaitu 4 partikel/m³, TPS Driyorejo yaitu 3 partikel/m³ dan PLTSa Benowo yaitu 3 partikel/m³ dan ukuran mikroplastik di keempat tempat tersebut ialah 133 µm - 3900 µm dengan jenis mikroplastik filament, fragmen, dan fiber.

Abstract

Al(III) complex with 1,4-benzenedicarboxylate ligand (Al-BDC) is a porous material that has the potential to be developed as an adsorbent or photocatalyst. This complex is often obtained by the solvothermal method at high temperature. This paper reports the synthesis of Al-BDC complex by solution method at room temperature from two different types of Al(III) salts, namely nitrate salt (complex 1) and chloride salt (complex 2). The synthesis of Al-BDC was conducted with Al(III):H2-BDC mol ratio of 2:3. The synthesized complexes were characterized by ATR-IR, powder XRD, UV Vis–DRS, and DTA–TGA. The results showed that white powders were obtained with a yield of 75.8% (complex 1) and 65.7% (complex 2). The presence of BDC ligands in both complexes was confirmed by the presence of typical absorption bands of C=O, C-O, and Al-O functional groups in their infrared spectra. Both complexes have different surface morphology and average crystallite sizes (28.63 nm – complex 1; 34.98 nm – complex 2), but the powder X-ray diffraction patterns, DTA-TGA thermograms, UV Vis-DRS spectra, and band gap energy values ​​of both complexes are considerably identical. Powder XRD diffraction analysis of both complexes shows a pattern that is identical to the known compound with a formula of {[Al(OH)(BDC)]·(H2BDC)0.69}n(CCDC No. 2179625) in which the compound forms 3D polymeric structure with terephthalic acid occupies the voids.
