“…The value of the percent of water absorbed will be inversely proportional to the water resistance of the plastic, the smaller the value of the percent of water absorbed by the plastic, the greater the water resistance of the plastic. The addition of glycerol as a plasticizer affects the value of water resistance to the film where the addition of glycerol increases the permeability to gases, water vapor, and solutes [11]. Another factor causing the high value of water absorption in the film is caused by its constituent components.…”

“…Today, the human population is increasing along with its demand which affects industrial and agricultural sector [1][2][3][4][5][6][7][8][9]. Besides that, especially Indonesia as agraris country has a large area of land even though it's an archipelago form [10][11][12][13][14].Weed growth in agricultural activities is often an obstacle to the growth and production of cultivated plants. This is due to competition between cultivated plants and weeds to obtain the necessary growth support sources such as light, space, nutrients and humidity.…”

The conventional mulch film generally produced from plastic to control of weed in agriculture activities. Nevertheless, the used of conventional mulch film has impact to pollute the environment, due to non-degradable. Therefore, mulch film from natural material derived yam nagara starch can be alternative to substitute the conventional mulch film that more eco-friendly. The aims of this study are to fabricate and characterization of mulch film from yam nagara starch which prepared by sprayed technique. The yam nagara starch prepared from local sweet potato varieties (Ipomoea batatas L) of Nagara, South Kalimantan. Fabrication of mulch film was conducted by mixed yam nagara starch with varied composition (0.25-0.75 wt%), hydrolysed keratin of chicken feather, corn gluten meal (CGM), acetate acid, and carbon black. The final solution of yam nagara mulch film was applied on top soil as plant medium using compressor spray gun and left to dry for 24 h. Furthermore, the sprayable mulch films were characterized by several parameters i.e., FTIR, water solubility, water uptake, tensile strength and elongation. Sprayable mulch film from yam nagara starch were successfully fabricated for agriculture application. The results show the sprayable mulch film with composition of 0.75 wt% yam nagara starch obtain a good plastic-like characteristics and may be affordable to be degraded due to easily to can soluble with water and high-water uptake properties. In other hand, sprayable mulch film from yam nagara starch in this work affordable to restrains weeds of the chilli plants for agriculture application.

Pectin from banana peels enable to increase silica membrane performance applied for photocatalytic-pervaporation of wetland saline water have been published by Assyaifi et al, [37]. Other study also used banana peels as bio-flocculant, as its content properties has potential for water clarification [38].…”

A comparative study was undertaken to investigate the potential of silica-pectin ultrafiltration membrane on varied operation pressure (0.1-0.3 MPa). Cross-flow ultrafiltration works were explored with tubular alumina substrates in single and multichannel configuration. The silica-pectin sol was prepared from TEOS as silica precursor by sol-gel method, afterward pectin was templated into the silica sol to induce carbon on it. Thereafter, both of single and multichannel alumina substrates was coated by the silica-pectin sol via inner coating technique. The study exhibited better performance of multichannel silica-pectin ultrafiltration membrane (with 4 bores) compared to the single channel membrane in terms of the permeate quality of UV254 rejection, as well as the permeate flux. The UV254 rejection of multichannel silica-pectin ultrafiltration membranes conducted over 84% in compliance with highest permeate fluxes of 234.3 L.m-2.h-1.bar-1 at high operation pressure (TMP 0.3 MPa). The multichannel ultrafiltration membrane permeate flux in this work is slightly high 60-75% over single channel. Hence, both single and multichannel silica-pectin membranes exhibited steady neutralized permeate fluxes under TMP 0.3 MPa conditions for natural 100% peat water concentration, which indicates that fouling is not occurred during filtration time up to 60 min. Therefore, multichannel silica-pectin ultrafiltration membrane in this work is success to treatment of natural peat water, that the natural organic matter removal was found to be fit for uses as clean water sources.

“…Other than that, banana peel is condsiderability for water clarification due to highly potential application as carbon carbon agent and bio-flocculant for water clarification [35]. Assyaifi et al, [36] has been also reported, pectin could increase silica membrane performance for wetland saline water desalination via photocatalyticpervaporation. The previous study have been succeed to fabricate silica-pectin membrane applied for wetland saline water desalination via pervaporation method [11,26,[37][38][39].…”

South Kalimantan-Indonesia is in the Southern part of Borneo which almost half of the population lives in remote areas. Geographically, people are isolated and have poor access to electricity as well as a clean water supply. It is very essential to ensure the availability of clean water produced from peat water to overcome future water shortages. This work performs the fabrication of multi-channel silica-based membranes applied for peat water ultrafiltration which is demonstrated under various transmembrane pressure (TMP) and top layer types. The silica based top layer membranes were fabricated from three different sources (silica-pectin, organosilica, and pure silica) via dipcoating method onto macroporous multi-channel alumina support (4 bore). Peat water was treated by multi-channel membranes through ultrafiltration process through cross flow system. According to the results, all multiples top layer pore size were obtained with range from 2.1 to 6 nm classified as mesoporous membranes. This process exhibited a promising outcome for removal natural organic matter (NOM) about 89-71% (UV254 rejection) at TMP 1-3 bar, respectively. Besides that, normalized permeate fluxes of that membrane excellently stable over 180 min operation time. It is concluded that silica based multichannel membranes are either compatible to treat peat water that has high number of NOM as well as excellent to overcome membrane fouling.
