Bioinspired conductive cellulose liquid-crystal hydrogels as multifunctional electrical skins
Authors: Zhang Zhuohao , Chen Zhuoyue , Wang Yu , Zhao Yuanjin 
Published: July 2020

Significance
We present an electronic skin (E-skin) based on hydroxypropyl cellulose composite hydrogel with stable cholesteric liquid-crystal structures and bright structural colors. Due to the utilization of the composite hydrogel with multiple responsiveness as a main building block, the E-skin can respond to pressure, tension, and temperature, and perform optical sensing of these external stimuli through color migration caused by internal structural changes. By adding carbon nanotubes, the composite hydrogel can simultaneously output these stimuli as electrical signals. Due to this dual-responsive mechanism under stimuli, the E-skin has great research value in health care and variable devices.

Abstract
The literature on collaborative governance has generated several comprehensive models detailing the conditions which collaborations must meet to achieve collaborative performance. The importance of each separate condition – such as the presence of incentives to participate, appropriate institutional designs, or facilitative leadership – has been validated in various studies. How all of these conditions interact with each other, and whether all of the conditions need to be present to achieve performance, is less well understood. Leveraging the rich resource of the newly created Collaborative Governance Case Database, this article explores the different pathways to performance used by 26 local collaborations. The analysis shows that the presence of strong incentives for partners to collaborate is a crucial condition for success; almost all performing cases shared this starting point. Performance was then achieved by combining strong incentives with either clear institutional design (e.g. explicit rules, transparent decision-making) or with intensive collaborative processes (e.g. face-to-face dialogue, knowledge sharing). This analysis shows that the current models for collaborative governance can serve as roadmaps, laying out all of the different conditions than may be important, but that collaborations can follow different routes to reach their objectives.

Abstract
The past decade has seen episodes of increasingly severe air pollution across much of the highly populated Indo-Gangetic Plain (IGP), particularly during the post-monsoon season when crop residue burning (CRB) is most prevalent. Recent studies have suggested that a major, possibly dominant contributor to this air quality decline is that northwest (NW) Indian rice residue burning has shifted later into the post-monsoon season, as an unintended consequence of a 2009 groundwater preservation policy that delayed the sowing of irrigated rice paddy. Here we combine air quality modelling of fine particulate matter (PM2.5) over IGP cities, with meteorology, fire and smoke emissions data to directly test this hypothesis. Our analysis of satellite-derived agricultural fires shows that an approximate 10 d shift in the timing of NW India post-monsoon residue burning occurred since the introduction of the 2009 groundwater preservation policy. For the air quality crisis of 2016, we found that NW Indian CRB timing shifts made a small contribution to worsening air quality (3% over Delhi) during the post-monsoon season. However, if the same agricultural fires were further delayed, air quality in the CRB source region (i.e. Ludhiana) and for Delhi could have deteriorated by 30% and 4.4%, respectively. Simulations for other years highlight strong inter-annual variabilities in the impact of these timing shifts, with the magnitude and even direction of PM2.5 concentration changes strongly dependent on specific meteorological conditions. Overall we find post-monsoon IGP air quality to be far more sensitive to meteorology and the amount of residue burned in the fields of NW India than to the timing shifts in residue burning. Our study calls for immediate actions to provide farmers affordable and sustainable alternatives to residue burning to hasten its effective prohibition, which is paramount to reducing the intensity of post-monsoon IGP air pollution episodes.

Abstract
Asteraceae is one of the cosmopolitan flowering plants spread in various regions, including Indonesia. Tridax procumbens, Eclipta prostrata, Eleutheranthera ruderalis, and Synedrella nodiflora are commonly found at Universitas Indonesia Campus, Depok. The research was conducted to describe the development stages of flowers and fruit forms from the four species of the Heliantheae tribe. Samples were taken by purposive sampling technique at several locations at Universitas Indonesia Campus, Depok. All stages of flower buds start from the smallest until the dry up fruit stages are collected and observed using the Dinolite device and the Dino capture 2.0 application. The results showed that there were variations in the number of stages of inflorescence-fruit development in the four species observed, with a range 9-16 stages. The flowering stage divided into four groups, namely pre-anthesis, beginning of anthesis, anthesis, and senescence. In the pre-anthesis stage, the inflorescence is still in the bud form and green; at the beginning of anthesis, the buds begin to open, and the corolla begins to appear; the anthesis stage is marked with a fully open corolla; while the senescence stage is characterized by a change in the corolla into brown and dries out. The four species observed have achene (cypsela) fruit with sizes ranging from 3-4 mm. The fruits have Achene (cypsela) with pronounce and a reduced part of distribution accessories. Seed distribution accessories are winged peripheral, lanceolate shaped central, capillary bristle, and reduced pappus.

Abstract

Hibiscus rosa-sinensis is a plant that has flowers with many variations in size, petal shape, petal colors, and chromosome number. Chromosome number and morphology information is the key to study its flower morphology and physiology. Chromosome Image Analyzing System IV (CHIAS IV) is software that used for mapping and identifying chromosome automatically. This report presents the results of chromosome analysis using CHIAS IV from four H. rosa-sinensis flower variations (single small red, single small pale red, single big red, and double red). Chromosome number and condensation patterns of individual chromosomes analysis suggested that these flower variations of H. rosa-sinensis exhibited polyploidy, with the smallest number found in single small pale red and the biggest number in single big red flower. CHIAS IV software is an effective tool to analyze chromosome image, especially to predict chromosome number, chromosome type, relative length, and condensation patterns of individual chromosome.

Abstract
Detergent wastewater contains high phosphate concentrations, so that if the wastewater is directly disposed of into a ditch or river then the wastewater can cause water pollution and eutrophication. Layered double hydroxides (LDHs) are synthetic materials with positively charged pyruvate type coatings of mixed metal hydroxides by chemical precipitation method. The purpose of this study is to find out the efficiency of Mg–Al(NO3) LDH on phosphate-containing detergent wastewater adsorption. The morphological structure of LDH by the SEM-EDS analysis method shows a loose lamellar structure with a particle size of about 1 μm, and the composition of Mg–Al(NO3) LDH by the XRF analysis method shows that the Mg and Al elements dominate more than other elements. Batch adsorption experimental conducted for detergent wastewater, which is where in this study the phosphate content was of ca. 51.50 mg / L. The equilibrium time of the adsorption process using Mg–Al(NO3) LDH is achieved after 60 minutes. The mole ratio of Mg : Al composition of LDH in the adsorption process has slightly affects the decrease in phosphate shown by a mole ratio of 1 : 1, 2 : 1 and 3 : 1 using Mg–Al (NO3) LDH as adsorbent at dose of 1 g, stirring rate of 100 rpm, 60 minutes, and at room temperature that is equal to 4.15 mg/L, 4.14 mg/L and 4.08 mg/L, respectively. Mg–Al(NO3) LDH is a promising adsorbent for phosphate removal in detergent wastewater.

Abstract
The bleaching process is critical to improving the colour, flavour, taste, and stability of the final oil products of palm oil. The bleaching process uses bleaching earth (BE), which after several cycles, becomes a waste called Spent Bleaching Earth (SBE). Impurities cover the surface of SBE from the purification process. Regeneration by utilizing acid can increase the absorption capacity of SBE. The purpose of this research is to obtain the optimal combination of nitric acid concentration and heating temperature in the regeneration process of SBE. Response Surface Method (RSM) with Central Composite Design (CCD) was employed, using two factors of concentration of nitric acid and the heating temperature. The responses analysed in this research include colour, absorption efficiency, and yield. The obtained optimum condition in the treatment was found in the concentration of nitric acid (0.75 M) and a heating temperature of 430.8°C. The results of this research indicated colour absorption efficiency of 95.7557%, the yield of 52.4846%. The verified optimal solution obtained was 94.68% of absorption efficiency and 51.43% of yield. The Regenerated Spent Bleaching Earth (RSBE) optimum conditions compared to BE. The colour absorption efficiency utilizing BE was 96.77%, 2% higher than that of RSBE at 94.68%. The value of RSBE colour absorption efficiency in optimum conditions similar to that of the BE.

Abstract
Kidal Village, located in Malang Regency, has around 106 traditional chicken poultries with hens chicken population of 1,463,720 chickens, producing of 85.8 tonnes chicken manure per day. Currently the chicken manure is remained untreated and left on the bottom of the chicken cage over one-year period. Such practice has resulted odour problems especially to those area nearby the chicken poultry. The aim of this study is to investigate the potential of valorizing chicken manure for biofertiliser, as well as the impact of co-composting of chicken manure (CiM) and cow manure (CoM) with blotong (B) on the compost physic-chemical quality. Randomized block design (RBD) was used in this study with factor of feedstock composition and C/N ratio. Composting was carried out under aerobic condition, with manual turning over, for 30 days period. The results demonstrated that CiM, CoM and blotong has high organic content, but lower C/N value. Blotong has higher moisture content (MC), which is suitable as co-composting feedstock to increase MC value of the mixture. This study also observed that all treatments combination have similar trends in terms of changes in temperature, pH and MC during composting process. The quality of resulted compost were well within the Indonesian standard value for organic compost (SNI 19-7030-2004), indicating that composting of chicken manure or cow manure with and without blotong may become potential alternative routes for tackling pollution problems from the untreated manure.
Anaerobic digestion of fungally pre-treated oil palm empty fruit bunches: energy and carbon emission footprint

Published: July 2020

Abstract
Oil palm empty fruit bunches (OPEFB) is one of the abundant lignocellulosic biomass in Indonesia. However, high lignin content in EFOB has becoming one of the obstacles in valorising it as bioenergy resources, as it is hardly broken down by the microorganisms. Therefore, pre-treatment is often needed to enhance the biodegradation process of organic content in OPEFB. The biological pre-treatment is besieged to enhance the utilisation of OPEFB as bioenergy resources. This study was aimed to investigate the impact of fungal pre-treatment on the OPEFB characteristics and its methane potential, and to estimate the energy and carbon emission saving from anaerobic digestion (AD) of OPEFB. In this study, OPEFB was treated using Phanerocheate chrysosporium under the standard condition and incubated for 7 and 14 days. The energy and carbon emission footprint were calculated using AD Assessment Tool (ADAT) software. The results showed that fungal pre-treatment was able to increase organic matter and enhance methane potential. Estimation on energy (i.e. electrical and heat), however, indicated a lower energy balance and carbon emissions saving for fungal pre-treated OPEFB. The higher moisture content (MC) on treated OPEFB may reduce the biogas and methane production. Yet, further research is still required to have an in-depth understanding of improving the efficacy of biogas production from OPEFB by incorporating other green pre-treatment approaches.

Published: July 2020

Abstract
Red amaranth (Alternanthera amoena Voss) is able to be used not only as food plants but also as herbal plants. Due to a high nutrient content of red amaranth, the demand of this plant is continue to increase. Even though this plant has high demand, its productivity is relatively low. The Sonic-bloom was experimented to be applied on the red amaranth cultivation to improve the productivity. The purpose of this research is to determine the effect of various frequencies and duration of sonic-bloom exposure on the growth of the red amaranth plant (Alternanthera amoena Voss). The frequencies were set at two levels i.e. 3000-5000Hz and 7000-9000 Hz with the exposure duration were 15, 30, 45, 60 and 75 minutes respectively. The results showed that the frequency and duration of exposure have a significant influence on the cultivation parameters of red amaranth plants. Frequency treatment of 3000-5000 Hz and 7000-9000 Hz produced plants with 25.93 cm and 18.83 cm of height, 13 strands of leaves, 42 cm and 30.6 cm of plants length, 2841.01 μm2 and 3688.51 μm2 of stomata area, and 14.84 gr and 7.58 gr of wet plant weight respectively. These results were significantly different compared to the control (without sonic bloom treatment) that have 8.53 cm of height, 7-13 strands of leaves, 14.87 cm of plants length, 972.98 μm2 of stomata area, and 0.55 gr of wet weight. The best treatment in this study is the frequency of 3000-5000 Hz with exposure duration of 75 minutes, concluding that Sonic Bloom technology is able to improve the productivity of red amaranth plants.

Published: July 2020

Abstract
Mackerel cracker is a type of fish crackers with the basic ingredients of mackerel fish. The potential of mackerel fish production reaches 5000 tons/year. Moreover, it is supported by the Indonesian government’s policies which currently make the marine sector a superior program, so that business licensing of marine and fishery products can be faster. Mackerel cracker processing industry in Tambakasri village, Malang, Indonesia is still facing problems in its production process. This research was conducted in a small and medium-sized enterprise (SMEs) Yuan Mina Kartika which produces various fish crackers. The constraints in the SMEs include 1) the amount of production that has not been optimal, because of the inadequate production tools; 2) the process of refining fish that still uses traditional tools; 3) the process of kneading is done manually so that it takes a long time and produces uneven mackerel fish mixture. The purpose of this study is to develop and to test a cracker dough kneading machine to increase the productivity and quality of cracker products. Dough kneading machine uses a kneading system that is driven using an electric motor and transmission. Engine capacity is designed for 100 kg/hour using 1.5 HP with some outputs of dough tube. The test results showed a significant increase in time efficiency in the kneading process as well as the quality of the cracker dough which was better than the manual method.
