Abstract

Limbah yang dihasilkan perusahaan JKLMN berupa limbah padat dan cair. Penanganan limbah cair diserahkan kepada Unit Pengolahan Limbah Air dan pihak ketiga membantu pemrosesan limbah padat. Fokus penelitian ini adalah pengolahan limbah secara anaerobik dengan menggunakan 3 (tiga) uji berupa BOD5, COD, dan TDS. Penerapan metode tersebut ditujukan untuk mengetahui potensi teknologi terhadap limbah cair yang dihasilkan perusahaan. Data pengamatan menunjukkan bahwa nilai parameter TDS mendekati nilai standar baku mutu pada hasil ulangan ketiga selama 6 (enam) hari. Peningkatan waktu tinggal limbah bukan merupakan solusi. Beban proses disebabkan limbah cair (segi jenis dan jumlah) yang menghasilkan ketidakseragaman produk dalam setiap waktu proses.

Abstract

Teknik pewarnaan kain batik dapat dilakukan dengan zat warna sintetik atau zat warna alam (ZWA). Keberadaan banyaknya permintaan konsumen, mampu menggerser keberadaan zat warna alam. Keunggulan zat warna sintetik antara lain memberikan keuntungan ekonomi, efisiensi waktu dan warna yang dihasilkan beragam. Kelemahan penggunaan zat warna sintetik adalah dampak lingkungan yang dihasilkan. Kandungan bahan sintetik sukar diuraikan sehingga perlu diupayakan kembali penggunaan ZWA . Salah satunya berasal dari tanaman perdu yaitu indigofera tinctoria. Tujuan penelitian ini adalah sejauh mana pengaruh konsentrasi daun indigofera pada beda perlakuan proses fermentasi (aerob dan anaerob) dan perlakuan penggunaan fiksasi terhadap daya tahan pencucian, daya tawahan luntur dan daya tahan sinar matahari.Bahan baku sampel yaitu kain katun dan sutera yang dicelup dengan ZWA fermentasi indigofera pada konsentrasi daun indigo 1kg/5L dan 1kg/10L, kemudian dilanjutkan dengan pencelupan fiksasi/non fiksasi sebagai variable bebas dan variable terikat adalah uji daya tahan. Hasil uji ketahanan daya tahan pencucian, daya tahan luntur dan daya tahan sinar mtahari menunjukkan bahwa penggunaan konsentrasi memiliki kategori nilai yang tidak jauh berbeda. Sedangkan pada variable perlakuan fiksasi/non fiksasi diperoleh kategori nilai terbaik rata-rata pada perlakuan fermetasi aerob.

Abstract

Elemental lead is one of the pollutants generated from batteries. To overcome this problem, technologies such as the use of bioadsorbents have been developed to reduce heavy metal content in wastewater. This study aims to determine the adsorption of lead metal ions (Pb2+) through the use of a water hyacinth (Eichhornia crassipe) bioadsorbent activated with nitric acid (HNO3). Another objective is to obtain the optimum adsorption time on battery industry waste discharges. Post-treatment characterization using FT-IR. Contact time variations (20, 30, 40, 50, 60, 70, 140, 210, and 280 minutes) were used to carry out the lead metal adsorption process on a standard solution of metal ions (Pb2+), 20 ppm. The results showed that the optimum contact time was 210 minutes. This achievement was used as the contact time for reducing the levels of Pb2+ metal ions. The quantity of the remaining Pb2+ metal ion content was 0.4184 ppm. Indirectly, the bioadsorbent performance was 94.8655%. Characterization through FT-IR equipment before activation of water hyacinth bioadsorbent gave results of O-H, C-H, C=O, and C-HO functional groups. These findings indicated the presence of lignin, hemicellulose, and cellulose compounds in the sample before activation. Then, the involvement of 1 N HNO3 solution (as an activator) resulted in a decrease in the quantity of C=O and C-OH functional groups. The process of applying the solution was able to break a number of chains between lignin and hemicellulose. After the adsorption process was given, the waste left the vibrations of O-H, C-H, and ≡C-H groups at wave numbers shifted in a smaller direction. This can occur due to changes in functional groups that have bound metal ions first.

Abstract

A sustainable alternative to traditional petroleum-based plastics, bioplastics produced from avocado seed starch can help alleviate some of the environmental challenges presented by plastic waste. However, these products still need to improve their mechanical properties and water resistance for industrial use. The purpose of this study is to find out how changes in the amounts of chitosan and polyvinyl alcohol (PVA) affect the mechanical strength, water resistance, and biodegradability of bioplastics made from avocado seed starch. The solution-casting method prepared starch-based bioplastics using chitosan (2.5–4.5 g), PVA (2.5–5%) as filler, and glycerol as a plasticizer. This study found that adding more chitosan increased the tensile strength, reaching a maximum value of 30.696±0.106 N/mm2 in the SNI 7188.7:2016, which was higher than the tensile strength value of the N3 sample. The samples N1 and M1 demonstrated the highest elongation at break of 35.700±4.776% and the lowest water uptake of 5.167%, indicating a 94.833% water resistance. The plastics underwent complete biodegradation under soil conditions after 60 days. This led to valuable results, confirming that avocado seed starch-based bioplastics, as engineering materials for food packaging, have enormous potential for application in the industry. This research needs to increase the water resistance or scale it up for industrial production
