Abstract

Kitin adalah homopolimer yang tersusun dari N-acetyl d-glucosamine dan glucosamine yang terikat dengan β 1–4 glycosidic. Kitin umumnya diperoleh dari ekstraksi kulit udang melalui proses deproteinasi dan demineralisasi dengan tahapan proses yang lama dan panjang. Pada penelitian ini dilakukan isolasi kitin dari jamur tiram sebagai alternatif sumber bahan baku dengan bantuan reaktor microwave. Proses ekstraksi dilakukan pada variasi waktu antara 5-60 menit untuk memperoleh kadar protein yang optimum. Selanjutnya dilakukan variasi temperatur antara 50-80°C untuk memperoleh kadar kitin. Hasil perolehan kadar protein tertinggi didapatkan pada waktu reaksi selama 60 menit yaitu 99,91% dan kadar kitin tertinggi diperoleh pada temperatur 80°C dengan kadar kitin yang didapatkan sebesar 7,10%.

Abstract

The paper aims to determine the effectiveness of several alternative technologies that have been applied in centralized domestic wastewater management systems, especially in West Java and Banten provinces, in the removal of domestic wastewater pollutant parameters. The study was conducted in SPALD-Ts, including the Anaerobic Baffle Reactor (ABR) system, the Anobic Filter (AF) system, the combined ABR + AF system, and the Extended Aeration. The analysis was performed by sampling at the inlet and outlet points of the system for three consecutive years with sampling times from 2021 - 2023. The results of the research show that the efficiency of pollutant parameter separation based on the best technology in the separation of domestic wastewater pollutant parameters is the SPALDT extended aeration technology, where this technology can separate pollutant parameters up to an average of 88.25%, but in this technology requires more cost and periodic maintenance.
