The result show that the highest concentration of glucose was obtained 7,27 g/L in biomass loading by using 3,5 gram of Tetraselmis chuii for 30 minute at 100oC

Mapping Social Media Texts as the Basis of Place-Making Process

AbstractThis paper explores the idea of ‘surface’ as a way to define the new landscape in place-making process. It examines how the new landscape could be generated regarding the virtual space of social media. The idea of ‘surface’ is explored through a case study in Twitter social media by analyzing the visual tracking of position based on specific texts, using Twitonomy database application. In this analysis, we investigate the tweet traffic of people's tweets, retweets, replies, mentions, and hashtags on specific topics leading to particular position of pinpoints concerning those topics. We trace the spatial distribution of individual texts about particular words. Through spatial mapping of those texts, we could curate the new landscape as a platform that visualizes the spatial network based on texts. Through this process, we could extract various possibilities of place-making in everyday life that becomes intertwine between the real and virtual space

Mixed matrix membrane incorporating of MgAl-CO3 layered-double-hydroxide for enhanced carbon dioxide separation

In this study, mixed matrix membranes were fabricated by incorporating MgAl-CO3 layered double hydroxides (LDH) into polysulfone (PSF) coated with low-cost commercial PEBAX polymer for enhancing CO2/CH4 separation. LDH was synthesized via a simple co-precipitation method and flat sheet membranes were fabricated by dry/wet inversion phase. The gas separation performance on pure PSF and LDH/PSF membranes were investigated. The physical property, chemical structure and membrane morphology were characterized by XRD, FTIR, and SEM. The sample membranes were tested with CO2 and CH4 gas for permeance performance and selectivity of CO2/CH4 was calculated. By incorporation of LDH, the CO2 permeance increased about 54.6%. LDH mixed matrix membranes displayed the 18.2 GPU of CO2 permeance and CO2/CH4 selectivity of 18.0. The LDH based membrane produces innovation in membrane technology by improving its morphology and permeance performance with great potential for large-scale CO2 capture and separation

Metal organic framework (MOF)-based composite filler incorporated thin film nanocomposite of hollow fiber membrane for carbon dioxide permeance

Composite filler dispersed in a selective layer has gather significant attention for gas separation because of potential in material robustness as well as enhancement in gas permeance and selectivity. Herein, this work focused on fabrication of metal–organic framework (MOF)-based composite filler incorporated thin film nanocomposite (TFN) of hollow fiber membrane using interfacial polymerization for CO2 permeance. Layered double hydroxide (LDH)@UiO-66-NH2 MOF composite fillers were developed and incorporated into polyamide selective layer, which were coated on the polysulfone substrate. The fabricated membranes were analyzed for ATR-FTIR and contact angle, and experimented for CO2 and CH4 permeation. It is noted that the TFN membrane both increased CO2 permeance and CO2/CH4 selectivity when comparing to thin film composite membrane. According to the results, composite filler combining MOF and LDH has future opportunities to adjust and increase the effectiveness of polymeric membranes for CO2 separation

Mgal-co3 layered double hydroxide as potential filler in substrate layer of composite membrane for enhanced carbon dioxide separation

The harvest of biogas resources is a promising means of delaying fossil-fuel depletion and simultaneously tackling climate change. Membrane technology is a promising method for an economic upgrade of biogas with the benefits of low energy consumption and environmentally friendliness, leading to intensive research in the fabrication of high-separation CO2 membranes. In this study, a substrate of composite membrane for CO2/CH4 separation was developed by incorporating MgAl-CO3 layered double hydroxides (LDH) synthesized via a simple co-precipitation method into polysulfone (PSf) polymer. The fabricated substrate hybrid LDH/PSf membrane was coated with a low-cost industrial PEBAX-polymer for minimizing surface defects as well as act as selective layer to form composite membrane for gas permeance. The physicochemical changes were analyzed by using XRD, FTIR, TGA, SEM, contact angle, AFM and tensile test. The impact of LDH loading (1, 3 and 5 wt%) in the substrate layer and operating pressure (1, 3 and 5 bar) on the composite membrane were thoroughly investigated. The composite membrane has increased the CO2 permeance by 55–113% as compared to pristine PSf membrane. Particularly, the composite membrane with 3.0 wt% LDH in the substrate layer has displayed the highest CO2/CH4 selectivity of 38.5. The distinct advantages in terms of facile fabrication with the right loading confer the LDH as potential filler in substrate layer of composite membrane with great potential for large-scale CO2 capture and separation

Potensi Perdagangan Komoditas Lada dari Indonesia ke Vietnam sebagai Salah Satu Pasar Non-Tradisional: Institut Pertanian Bogor

The trend of slowing export demand from Indonesia's main export destination countries currently requires Indonesia to diversify its exports to other countries. Vietnam is a country that has the potential as a destination for export diversification. The most potential product to be utilized in this export diversification is pepper. This study aims to analyze the potential and competitiveness of pepper exports in the Vietnamese market; as well as analyze tariff and non-tariff barriers to pepper exports to the Vietnamese market. The data used in this study are time series data for 2010-2019 sourced from the United Nations of Commodity Trade Database (UN-Comtrade) and the World Integrated Trade Solution (WITS). The analysis will be carried out through the analysis of ISP, IIT, RCA, EPD, as well as FI and CR. As for the results of this study, trade integration between Indonesia and Vietnam is still very weak (IIT), the competitiveness of Indonesia's pepper commodity is still low when compared to other countries in the Vietnam market (EPD), and Indonesia's pepper exports to Vietnam are affected by Non- Tariff Measure/NTM (FI and CR). Although, the Indonesian pepper commodity in the Vietnamese market is the most superior commodity (ISP), has great potential (RCA), and has a fairly high competitiveness (X-Model). Therefore, the recommended policy of the government is to increase world trade cooperation; internal improvements through the establishment of pepper farmer institutions, product diversification, and improving pepper quality; as well as pay attention to the supervision of aspects of Quality Control of pepper
