Abstract

Teknik pewarnaan kain tradisional batik telah diakui oleh UNESCO sebagai warisan kemanusiaan untuk budaya lisan dan nonbendawi. Industri batik di Indonesia didominasi oleh usaha kecil dan menengah yang belum memiliki fasilitas instalasi pengolahan air limbah (IPAL) memadai, seperti halnya di Kampung Batik Pasundan. Air limbah industri batik mengandung bahan kimia berbahaya, pewarna, dan logam berat yang dapat menimbulkan masalah lingkungan dan kesehatan. Pada studi kasus ini, lahan basah buatan dirancang melibatkan interaksi antara tanaman dan mikroorganisme untuk pengolahan air limbah. Sistem pembangkit listrik tenaga mikrohidro, yang terhubung ke lahan basah buatan, memanfaatkan aliran air untuk menghasilkan listrik dan menyediakan pasokan energi untuk proses produksi batik. Kapasitas air limbah sebesar 12.000 L/hari memungkinkan untuk menggerakkan turbin menghasilkan 1.368,75 kWh listrik per tahun, sekitar 14% dari total kebutuhan listrik Kampung Batik Pasundan. Desain sistem ini menawarkan solusi pengolahan air limbah industri batik yang berkelanjutan dengan integrasi konservasi energi.

Abstract

Dammar resin (Agathis dammara) is a mixture of various organic polymers in a solid or semi-solid form that can be utilised as an essential oil source. This study extracted the essential oil from dammar resin using microwave-assisted hydro-distillation (MAHD), considering its ability to extract the product in a short period with only a small amount of solvent. This study investigates the effect of solvent and extraction time on the yield of dammar resin extract. Results showed that the highest yields are 27.500, 22.902, and 15.392% for distilled water, a 1:1 v/v mixture of ethyl acetate and distilled water, and a 1:1 v/v mixture of hexane and distilled water as solvents, respectively. The optimum extraction time was different for different solvents, in the 60–90 minute range. Based on the gas chromatography-mass spectrometry (GC-MS) analysis, the dammar resin extract contains several groups of components, including alcohol and sesquiterpene groups. The alcohol group was higher after extraction using an ethyl acetate and distilled water mixture, especially 2-Butoxyethanol, with a yield of 39.706%. Meanwhile, a mixture of hexane and distilled water increased the sesquiterpene compounds in products such as Germacrene D, yielding 19.975%.

Abstract

Pencemaran logam berat seperti timbal (Pb), kadmium (Cd), dan merkuri (Hg) dari limbah industri tekstil, pertambangan, dan oleokimia menjadi ancaman serius bagi kesehatan dan lingkungan. Mikroalga berpotensi besar sebagai biosorben alami untuk bioremediasi, namun efisiensinya terbatas akibat rendahnya jumlah gugus aktif pada dinding sel. Kajian ini meninjau potensi mikroalga termodifikasi melalui studi pustaka dari berbagai penelitian nasional dan internasional. Modifikasi kimia seperti aktivasi asam, basa, dan esterifikasi terbukti meningkatkan densitas gugus fungsional (karboksil, hidroksil, amina, dan sulfat), sehingga memperkuat interaksi dengan ion logam. Chlorella vulgaris menunjukkan efisiensi penyerapan Pb(II) lebih dari 90% pada pH netral, sedangkan Spirulina platensis hasil esterifikasi mampu meningkatkan kapasitas adsorpsi Cr(VI) hingga 40%. Teknik imobilisasi dan komposit magnetik juga terbukti memperpanjang umur pakai biosorben hingga lima siklus regenerasi tanpa penurunan signifikan. Meskipun masih menghadapi tantangan teknis dan ekonomis, hasil studi menunjukkan bahwa mikroalga termodifikasi berpotensi sebagai solusi bioremediasi yang efisien, murah, dan berkelanjutan untuk pengelolaan limbah logam berat di Indonesia.

Abstract

Scaling up the cultivation of Chlorella vulgaris often results in differences in growth performance compared to laboratory-scale cultivation due to increased sensitivity to environmental factors. This study examined the interaction between light color, salinity, and the scale-up process at cultivation volumes of 1, 5, and 10 L using synthetic NaCl media and artificial seawater (ASW). Growth was monitored via optical density measurements. The results indicated that inoculum is a key factor factor influencing the success of scale-up. Cultures transferred during the logarithmic growth phase adapted more quickly and maintained exponential growth, while inoculum from the decline phase showed slower recovery and lower cell density. Red light minimized light stress and promoted higher cell density in both media. Lower salinity promoted faster growth and earlier peak attainment. Changes in dry biomass pigments indicate carotenoid accumulation under high salinity and light stress. The highest biomass yield was achieved when harvested during the logarithmic phase, with ASW medium providing higher productivity. Overall, optimizing inoculum age, light, and salinity is crucial for improving production efficiency during the C. vulgaris scale-up process.
