Chitosan and silica have been used widely in the wastewater treatment process and also easily formed into membranes. The purpose of this study is to analyze characteristics of membrane flux , which is one indicator of the quality of the performance of the membrane. The membranes used in the filtration process is made of chitosan and silica rice husk biosilika with inverse phase technique.

The rapid growth of the industry is giving positive effects for humans by providing daily needs and supporting economic development. However, the industrial process also releases pollution to the environment, which can cause water scarcity, biodiversity loss, and climate change.
Removing these pollutants from various industrial wastes is a requirement for ensuring proper water quality for human consumption, agricultural use, and environmental safety.
This work aims to explain the use of natural resources as a source of valuable compounds that can be used in wastewater treatment, particularly in Indonesia, by adopting a literature study method reviewing both national and international references.
Chitosan is an effective bio-absorbent pollutant because of its high level of deacetylation and free amino groups, making it polycationic which is capable of being bound to metals, proteins, and dyes.
Chitosan membranes can be applied only with chitosan material and composites: chitosan-Polyethylene Glycol PEG , chitosan-Poly Vinyl Alcohol, chitosan-biosilica, chitosan-PVA-silica, chitosan-alginate, chitosan-cellulose, and chitosan-silica. Chitosan has the ability as a coagulant and reducing water turbidity.
Since there is a high abundance of chitosan raw material in Indonesia, it is supposed to be able to support the application of chitosan as a natural purifying agent considering its high ability to absorb heavy metal and some dangerous materials.

Pollution has been occured in our environment due to daily life waste, industrial and using of peptiside in agroindustrial farm. Over usuage and dose of peptiside could be harmfull to the farm environment especially for fish farm. Measurement of membrane potential of fish egg cells is a simple metode to investigate water polution level. Membrane potential of fish egg cells can be measured using microelectrode probe which is connected to an electrometer.

Cells are the most important structural and functional part of any organism. Cells are protected by cell membranes that envelop cells, and separate cells with their environment. The effectiveness of the work of a cell membrane can be disrupted for various reasons, one of which is pesticide contamination. Pesticides in cells can damage cell metabolism or cell membrane permeability.
Biologi sintetis SynBio adalah cabang antar bidang biologi dan teknik. Bidang ini menggabungkan disiplin ilmu dari dalam domain ini, seperti bioteknologi, rekayasa genetika, biologi molekular, rekayasa molekular, biologi sistem, ilmu membran, biofisika, teknik kimia dan biologi, teknik listrik dan komputer, teknik listrik dan komputer, teknik kontrol dan biologi evolusi. Biologi sintetis menerapkan disiplin ilmu ini untuk membangun sistem biologis buatan untuk penelitian, teknik, dan aplikasi medis. Biologi sintetis dilihat secara berbeda oleh ahli biologi dan insinyur. Awalnya dilihat sebagai bagian dari biologi, dalam beberapa tahun terakhir peranan teknik elektro dan kimia menjadi lebih penting. Sebagai contoh, satu deskripsi menunjuk biologi sintetis sebagai "disiplin yang muncul yang menggunakan prinsip-prinsip teknik untuk merancang dan merakit komponen biologi".
