Green manufacturing adalah konsep sistem produksi berkelanjutan dalam menghasilkan sebuah produk, dengan meminimalkan limbah dan polusi di dalam prosesnya. Salah satu penilaian kinerja green manufacturing adalah program PROPER yaitu program peringkat kinerja perusahaan oleh kementrian lingkungan hidup. PT X adalah pabrik yang memproduksi brankas atau lemari besi dan filing cabinet tahan api. Limbah yang diolah di Instalasi Pengolahan Air Limbah berasal dari proses painting baik dari bahan kimia proses pembersihan pengkondisian metal sebelum dicat, maupun dari material cat itu sendiri. Limbah juga datang dari sisa campuran beton yang merupakan bahan utama sebagai pengisi lemari besi. Proses pengolahan limbah menggunakan metoda fisik dan kimia agar buangan limbah memenuhi baku mutu Kawasan Industri MM2100 Bekasi. Kajian ini dilakukan untuk merekayasa campuran beton dengan memanfaatkan limbah sludge dan rekayasa instalasi air untuk memanfaatkan air limbah menjadi air penunjang proses produksi. Kajian dilakukan dengan cara mengumpulkan data primer dan sekunder, pengamatan langsung ke lapangan, pengambilan dan pengujian sampel. Pembuatan sampel kubus beton dilakukan untuk subtitusi sludge 0%, 5%, 10%, 15% dan 20% masing-masing 3 sample untuk Uji Tekan 7 hari dan 3 sample untuk Uji Tekan 28 hari. Dari hasil pengujian di ketahui nilai kuat tekan subtitusi 10 % sebesar 310 (kN), lebih besar dari nilai minimum yaitu 300 (kN) sehingga bisa di gunakan sebagai campuran beton produk. Subtitusi 5% sampai dengan 20% bisa digunakan untuk ruko 5 lantai s/d jalan tol atau jalan negara.

Aim: This study was focused on the formulation of the multi-unit extended-release peroral delivery device of lamotrigine for better management of epilepsy. Background: The single-unit extended-release peroral preparations often suffer from all-or-none effect. A significant number of multi-unit delivery systems have been reported as a solution to this problem. But most of them are found to be composed of synthetic, semi-synthetic or their combination having physiological toxicity as well as negative environmental impact. Therefore, fabrication and formulation of multi-unit extended-release peroral preparations with natural, non-toxic, biodegradable polymers employing green manufacturing processes are being appreciated worldwide. Objective: Lamotrigine-loaded extended-release multi-unit beads have been fabricated with the incorporation of a natural polysaccharide Cassia fistula seed gum in calcium-cross-linked alginate matrix employing a simple green process and 23 full factorial design. Methods: The total polymer concentration, polymer ratio and [CaCl2] were considered as independent formulation variables with two different levels of each for the experiment-design. The extended-release beads were then prepared by the ionotropic gelation method using calcium chloride as the crosslinkerions provider. The beads were then evaluated for drug encapsulation efficiency and drug release. ANOVA of all the dependent variables such as DEE, cumulative % drug release at 2h, 5h, 12h, rate constant and dissolution similarity factor (f2) was done by 23 full factorial design using Design-Expert software along with numerical optimization of the independent variables in order to meet USP-reference release profile. Results: The optimized batch showed excellent outcomes with DEE of 84.7 ± 2.7 (%), CPR2h of 8.41± 2.96 (%), CPR5h of 36.8± 4.7 (%), CPR12h of 87.3 ± 3.64 (%) and f2 of 65.9. Conclusion: This approach of the development of multi-unit oral devices utilizing natural polysaccharides might be inspiring towards the world-wide effort for green manufacturing of sustained-release drug products by the QbD route.
