Abstract

The purpose of this research is to make laboratory-scale bioethanol from agroindustrial waste, namely rice husk through hydrolysis, fermentation, and distillation methods, determine %yield, and characterize bioethanol. The method used was experimental. The results and conclusions obtained are bioethanol that smells like tape, colorless with %yield as much as 3,32%, density of 0.8818 g/mL, viscosity of 0.7408 cP, and blue flame formed during the flame test. Based on the characterization results, the bioethanol obtained has not met the SNI standards, which is suspected because it still contains water content caused by less pure ethanol from the distillation process.

Abstract

The exponential growth in printed circuit boards (PCBs) waste, presents an urgent environmental and economic challenge. PCBs contain silver which has a high potential economic value. The high production of waste and the potential economic value make it important to recycle PCB waste. Recycling can be conducted by leaching silver using Deep Eutectic Solvent (DES). DES is environmentally friendly and able to form complexes with various types of metals. This research aims to study the effect of the HBD carbon chain length of oxalic acid, malonic acid, and succinic acid from choline chloride-based eutectic solvents (DES) on the efficiency of leaching silver from Printed Circuit Board (PCB) waste. Optimization of the solid/liquid ratio, time, and temperature is carried out to obtain optimum leaching conditions. The synthesis results show that DES oxaline 2:1, malin 1:1, and succilin 2:1 have good stability, forming a colorless, clear, and viscous solution. FTIR analysis shows a shift in the wave number of the -OH group due to hydrogen bond interactions between HBA and HBD molecules in the formation of DES. The leaching yield of DES against standard silver oxide was measured using AAS. DES oxaline 2:1 has the greatest efficiency compared to other DES variations. The results of optimizing standard silver leaching with DES oxaline showed that the S/L ratio was 40 mg/mL, with a time of 18 hours, at a temperature of 60°C which resulted in a recovery percentage of 90.90%, while for the PCB waste sample yielded an efficiency of 99.38%. The eutectic solvent oxaline has the potential to be an environmentally friendly solvent that is efficient in leaching silver from PCB electronic waste.

Abstract

Tujuan utama penelitian ini adalah untuk menentukan formulasi yang dapat memberikan keseimbangan terbaik antara kekuatan mekanik, ketahanan terhadap air, dan laju degradasi. Penelitian ini dirancang menggunakan metode eksperimental dengan formulasi pati limbah kentang sebagai bahan utama (1.5%, 2.5% dan 3.5% b/v), penambahan kitosan, gliserol sebagai plasticizer, serta asam sitrat sebagai agen crosslinking. Proses pembuatan bioplastik dilakukan dengan metode casting, dimana larutan pati dan kitosan dicampur bersama gliserol dan asam sitrat, kemudian dicetak dan dikeringkan pada suhu terkontrol hingga terbentuk lembaran film bioplastik. Karakterisasi material meliputi pengukuran ketebalan, laju transmisi uap air (WVTR), biodegradabilitas, kekuatan tarik, dan elongasi. Hasil menunjukkan bahwa peningkatan konsentrasi pati berpengaruh pada kenaikan ketebalan film dan kekuatan tarik, namun cenderung menurunkan nilai elongasi. Laju transmisi uap air menurun seiring peningkatan kandungan pati, mengindikasikan peningkatan kemampuan sebagai penghalang uap air. Semua variasi bioplastik terurai dalam tanah lembap dalam waktu relatif singkat. Formulasi pati 3.5% menunjukkan karakteristik terbaik dalam hal kekuatan mekanik, dan sifat penghalang uap air, sehingga dinilai paling potensial untuk aplikasi kemasan pangan.
