Abstract

In South Kalimantan, peat water is the main water sources for local people. But peat water has high iron content. It cannot be consumed directly and need further treatment. Adsorption is the most common technology to treat peat water. The goal of this research is to study sago waste adsorbent for iron removal in peat water. Citric acid was employed as activating agent in the sago waste activated carbon adsorbent fabrication. Carbonization process was done at 300 ℃ with 70, 80, 90, 100, 110 and 120 minutes of time variation. After treatment using the adsorbent, iron content was tested via Atomic Absorption Spectrophotometry (AAS). While, Fourier Transform Infra-Red (FTIR) were carried out to investigate the functional groups of sago pith waste activated carbon (SPWAC) and sago pith waste unactivated carbon (SPWUC). The experiment results show iron could be removed until 82% with iron concentration of 0.05 mg/l at 80 minutes. SPWAC and SPWUC have functional groups such as alkenes (C-H and C=C), carbonyl (C=O and C-O) and hydroxyl (O-H). Fe concentrations are still meet water quality standard according to No. 492/Menkes/PER/IV/2010 which is 0.3 mg/L. Therefore, adsorption uses sago pith waste activated carbon is an effective and inexpensive water treatment.

Abstract

Water scarcity is the main issues in Indonesia especially for coastal areas. As a consequence, the water has high salinity of >50.000 ppm salt concentration where an appropriate treatment is necessary before consumed. In this case, desalination process could be carried out using inorganic silica membranes. However, during the process the pore of silica membranes were collapsed due to the directly contact of pores to water molecules for a long term performance. Thereby, in this work the innovation of membrane fabrication using carbon templated in silica matrices has been successfully fabricated. Literally, the carbon templates could be improving the membrane hydro-stability. The interlayer-free silica-pectin membrane was fabricated using TEOS as silica precursor and carbon templated from pectin apple. All membranes waere calcined in variance temperature of 300 and 400°C via Rapid Thermal Processing (RTP). The FTIR results show some functionalization of siloxane, silanol and a new bond of silica-carbon. Whereas, the SEM images show the membrane morphology that the membrane not dense and crack-free with thin film's thickness of ~ 1 μm. An excellent condition of interlayer-free silica-pectin membrane was obtained at pectin concentration of 2.5 %wt. (300°C) and 0.5 %wt. (400°C) with highest functionalization of siloxane and silica-carbon bonds. The existence of silica-carbon bonds were capable to enhancing the membrane hydro-stability. In addition, the carbon chains were contributed to form a smaller pores but also robust pore structures. Those fabricated membranes were shown a good promising due to fast and low cost fabrication with high quality to applicate in seawater desalination.

Abstract

Wetland in South Kalimantan is one of surface water sources to provide clean water. However, seawater intrusion has spread into the wetland aquifer and reduce the quality of water. Silica-pectin membrane is a promising technology for desalination. The membranes were tested for desalination by pervaporation at room temperature (~25 °C). During pervaporation process, the water contacts to membrane and the separation is started to occurs as vapour phase by maintaining vacuum pressure (~1 bar). The permeate was collected in the cold trap after condensed using nitrogen liquid. The purpose of this research was to investigate the performance of interlayer-free silica pectin membrane for wetland saline water. Experimental results shows the fluxes of membrane are 0.35 and 0.19 kg.m-2 h-1 ( pectin 0%wt); 0.23 and 0.16 kg.m-2 h-1 (pectin 0.1%wt); 0.58 and 3.63 kg.m-2 h-1 (pectin 0.5%wt); 3.40 and 0.12 kg.m-2 h-1 (pectin 2.5%wt) calcined at 300 and 400 °C, respectively. Natural organic matter (NOM) and salt concentration in wetland saline water can reduce the fluxes up to (~98%). Nevertheless, overall salt rejection of membranes achieved >99%. It was found that low calcination gives better performance at high pectin concentration. While pectin concentration was limited at high calcination.

Abstract

Abstract: Hydrogel films are sheet materials that form a 3D network structure and can be fabricated from one or more constituent materials. A combination of two natural polymers, namely carboxymethyl cellulose (CMC) derived from water hyacinth stems (WHS) and banana peel pectin, constructs these hydrogel films that are used as coating materials for food packaging. Citric acid replenishment to stabilize the cross-linking of the hydrogel films. This study is intended to determine the effect of WHSCMC, pectin, and citric acid on the swelling abilities and tensile performances of hydrogel films. CMC synthesis begins with harvesting water hyacinth stems obtained from the Gambut area waters in South Kalimantan, Indonesia. Then carried out the extraction and bleaching processes of cellulose. Cellulose extract powder was processed in two stages, videlicet alkalization and carboxymethylation, to obtain cellulose derivatives in the form of CMC. The results of WHSCMC were analyzed using FT-IR (Fourier Transform Infra-Red) and compared with commercial CMC. Giving results with significant similarity at the peaks of 998 cm-1 and 1015 cm-1, specifically the ether glycosidic group. Fabrication of hydrogel films combines WHSCMC and banana peel pectin with various compositions (100:0, 90:10, 70:30, and 50:50 wt.%) with added citric acid as an aid for crosslinking at various concentrations (5, 10, and 15 wt.%). Hydrogel films sample 70:30, 5 wt.% (CPc-5) gave optimum results from the characterization of hydrogel films related to food packaging application coatings in the form of swelling ability of 6,647 g/g, tensile strength of 11,770 MPa, and elongation test of 11,896%. FT-IR analysis of CPc-5 indicates that there are carboxyl groups (COO-) and hydroxyl groups (-OH), which play a role in the formation of cross-links and hydrophilic properties.Abstrak: Film hidrogel merupakan material lembaran yang membentuk struktur jaringan 3D dan dapat dibuat dari satu atau lebih bahan penyusun.

Abstract

Wetland water is opted as the source of domestic water supply when the availability of clean fresh water is scarce. Wetland water requires proper treatment due to the high concentration of organic matter and high salinity, particularly in the dry season. This research aims to synthesize, characterize, and investigate the performance of polyvinylidene fluoride (PVDF)-TiO2 hollow fiber membrane for wetland saline water desalination via pervaporation. The PVDF-TiO2 hollow fiber membranes were fabricated through the dry wet spinning method under various air gaps (10, 15, and 20 cm). Then, the resulting membranes were tested in a pervaporation process at temperatures of 25, 40, and 60°C. Results show that the incorporation of TiO2 into the PVDF matrix imparted hydrophilicity properties into the resultant membranes. The presence of TiO2 was confirmed by the TiO2 stretching vibration at 1640 cm-1 (FTIR) and the TiO2 phase at diffraction peaks at 25.5 and 37°. The membranes exhibited the highest water flux (7.48 kg/m2.h) and salt rejection ( 99.5%) at 40°C. Overall, the developed PVDF-TiO2 hollow fiber membranes showed encouraging results and demonstrated their effectiveness for the desalination of wetland saline water.

Abstract

Abstract: Polyvinylidene fluoride (PVDF) hollow fiber membranes have excellent mechanical properties and chemical stability. However, their hydrophobicity can lead to fouling and hinder permeability. Modifying this hydrophobicity is challenging due to PVDF's complex polymorphous structures, with the β-phase offering superior fouling resistance. One approach to improve PVDF hollow fiber membranes is the addition of inorganic additive materials to reduce hydrophobicity. The objective of this study is to offer new insights into the preparation of PVDF hollow fiber membranes using wet spinning with various additives, such as TiO2 and SBE. The investigation focused on the functional groups of PVDF in both the α and β phases. The membrane was fabricated using regenerated SBE and TiO2, which were incorporated through dope solution preparation and phase inversion through a wet spinning technique. The study used the Fourier Transform Infrared (FTIR) technique to characterize the PVDF hollow fiber membranes. The study found that the PVDF hollow fiber membranes exhibit differences in α and β phase crystalline structures when combined with various additives. The addition of SBE to PVDF hollow fiber membranes results in a dominant β-phase crystalline structure, as indicated by the relative fraction of 0.70 and the largest peak area of 2.27. This has successfully improved the hydrophilic properties of the PVDF-SBE hollow fiber membrane.Abstrak: Membran hollow fiber polyvinylidene fluoride (PVDF) memiliki sifat mekanik dan stabilitas kimia yang sangat baik. Namun, sifat hidrofobiknya dapat menyebabkan fouling dan menurunkan permeabilitas membran. Oleh karena itu memodifikasi sifat hidrofobisitas ini cukup menantang karena struktur polimorf PVDF yang kompleks, terutama dengan keberadaan fase β yang memberikan ketahanan terhadap fouling. Salah satu pendekatan yang dapat dilakukan untuk meningkatkan membran hollow fiber PVDF adalah dengan penambahan bahan aditif anorganik untuk mengurangi hidrofobisitas. Tujuan dari penelitian ini adalah untuk menguak wawasan baru dalam pembuatan membran serat berongga PVDF menggunakan wet spinning dengan berbagai aditif, seperti TiO2 dan SBE. Investigasi difokuskan pada gugus fungsional PVDF berupa fase α dan β.  Membran dibuat dengan menggunakan TiO2 dan SBE regenerasi, yang dibuat melalui pembuatan larutan dope dan inversi fasa melalui metode wet spinning. Penelitian ini menggunakan teknik Fourier Transform Infrared (FTIR) untuk mengkarakterisasi membran serat berongga PVDF. Penelitian ini menemukan bahwa membran serat berongga PVDF menunjukkan perbedaan struktur kristal fase α dan β ketika dikombinasikan dengan berbagai aditif. Penambahan SBE pada membran serat berongga PVDF menghasilkan struktur kristal fase β yang dominan, seperti yang ditunjukkan oleh fraksi relatif 0,70 dan area puncak terbesar 2,27. Hal ini telah berhasil meningkatkan sifat hidrofilik membran serat berongga PVDF-SBE.

Abstract

The role of corporations in applying sustainable principles cannot be separated from the commitment of corporations in carrying out social and environmental responsibility or corporate social responsibility (CSR). In practice, corporations must also have clear CSR commitments. However, the implementation of CSR in Indonesia has not been optimally carried out by corporations from a sustainable development perspective. Corporate Social Responsibility is still considered an obligation, it has not become a good character inherent in the corporation. This paper will discuss about the optimization of CSR in Indonesia by analyzing the normative legal measures that can be taken against the CSR legislation seen from the prospects and challenges that Indonesia has. The approach method used in this study is a normative juridical approach with descriptive analytical research specifications and analyzed by qualitative normative methods. The problem in managing CSR in Indonesia is that the concept of CSR is not aligned with sustainable principles. From this, an understanding can be drawn that basically the optimization that is felt to be the most appropriate when viewed from the existing gaps in CSR regulation is the making of pentahelix policies that involve the government, society, non-governmental organizations, academics, and the media.
