The economic aspect of batik stamp made of can waste
Authors: Syamwil R , Kartini  
Published: March 2021

AbstractThe traditional batik stamp (canting cap) is relatively expensive tool, made of copper. The lack and high price of copper made it difficult forbatik stampcrafter to market their products, and made alternative materials from wood and paper/cardboard. The weakness of wood and paper stamp is that the resulting rough motifs and not long lasting. The use of used can is environmentally friendly, assure sustainability by recycling waste of cans which causes environmental problems. This study departs from research on the innovation ofCantikbatik stamp made of biscuit can waste, focusing on the economic aspect of the innovations. This analysis was important to see the advantages and or weaknesses of the can stamp, as a basis for applying the research product in thebatik stamprafter community. Descriptive research was conducted for cost calculation, analysis of selling power, and service life. The cost of can batik stamp found cheaper than copper stamp, since the materials is low cost, though 21% copper content was still needed forisen-isen, ganjelan, and bajelan part. However the labor processing cost was equal. The processing time efficiency was lower, while level of difficulty in processing was higher, because cans are harder and more difficult to shape and cut compare with copper. The durability of the can batik stamp was lower than copper, because can is easily oxidized and corrosive, so it will be more difficult to maintain. The risk of rust can be reduced by processing the final stamp in hotgondorukem (resina colophonium). For long lasting product, the can stamp has to storage in a dry and low humidity place, in hung position.

Published: March 2021

Abstract
This paper presents a unified control for single stage grid-connected system with non-linear load. The proposed control not only ensures power injection into the grid, but also shows its advantage of controlling both active and reactive powers as well as harmonics restraints. This paper explains also the advantage of single stage using quasi- z source inverter (QZSI) which plays the buck/boost operation using space vector pulse width modulation technique (SVPWM) for shoot through insertion during the modulation period. Instantaneous power theory is used to simplify the implementation of the control design for both the inner and outer layer as well as for the reference current generation. To take off the challenge of tracking the maximum power point (MPPT) in any condition, including change in solar irradiance, fuzzy technique is used. Thereby, exhibiting its robustness and adaptability. Besides, to ameliorate the efficiency of the system, the well repute particle swarm optimization algorithm (PSO) is employed to improve the PI controllers’ parameters. Finally matlab/Simulink environment is used to implement and to confirm the effectiveness and the feasibility of the proposed control strategy as well as the optimization method.

Authors: Liang Dong , Yang Fan 
Published: March 2021

Abstract
In this paper, a proposed inductor design method with toroidal powder core is presented to minimize the total power loss of boost converter. Losses in the inductor, capacitor and semiconductors are considered. The total power loss function of the boost converter as an objective function is calculated iteratively by using the genetic algorithm (GA) in MATLAB. Then the optimal core size, permeability and number of turns can be obtained, which minimize the total power loss. Finally, the experimental results verify the proposed inductor design method is feasible by comparing with the general inductor design method in an 800W boost converter operating at 50kHz.

Authors: Zhang Yongzhong , Zhang Sicheng 
Published: March 2021

Abstract
Polysaccharides from Taraxacum mongolicum were extracted using cellulase-assisted extraction technology. Based on the results of single factor experiments, three independent variables extraction time, temperature and pH were selected for investigation. Response surface methodology (RSM) was used to optimize the extraction conditions. The optimal conditions were as follows: extraction time, 105.07 min; extraction temperature, 47.49°C; extraction pH, 4.81. Under such conditions, the yield of polysaccharides was 13.75% (w/w), and the yield obtained by cellulase-assisted extraction method was remarkably higher than the hot water extraction. In vitro assays, scavenging activity of 1, 1-Diphenyl-2-picrylhydrazxyl (DPPH) radical and superoxide anion radical showed that the polysaccharides from T. mongolicum had definite antioxidant activities, and polysaccharides extracted from different parts of T. mongolicum had different antioxidant activity, which shows: inflorescence > leaf > root. These results exhibit that cellulase-assisted extraction is an advisable method for T. mongolicum polysaccharides and polysaccharides could be explored as potential antioxidant to use in medicine or functional food.

Published: March 2021

Abstract
The UV-Vis absorption and fluorescence spectra of proanthocyanidins at different pH values were studied, and the change of absorption peak position was analyzed. The intermediate stable states of proanthocyanidins in different pH conditions, the electron transition modes and emission spectra of these steady states were analyzed. Eight parts of proanthocyanidins, each with mass of 1.00 mg, were added to acetic acid buffer solution with different pH in turn. The absorption of samples at the same pH concentration was measured by UV-visible spectrophotometer and fluorescence spectrophotometer, spectrogram analysis was carried out. The absorption peak wavelength of proanthocyanidins did not change obviously in acid condition, the quantum yield of proanthocyanidins was low in different pH solutions, and the excited molecules returned to the ground state mainly by non-radiative transition. Under the same temperature conditions, the stability of proanthocyanidins decreased with the increase of pH, and the color of the solution ranged from orange to red. The charge distribution of hydroxyl groups analyzed the ability of combining free radicals at different sites of proanthocyanidins with hydroxyl groups, which suggested that proanthocyanidins may have better antioxidant activity.

Published: March 2021

Abstract
The influence silver substitution at 0%-5% on the fundamental absorption edge of CsPbBr3 perovskites was studied. Here we examine the optical performance (diffuse reflectance spectroscopy) from Ag-CsPbBr3 perovskites samples. The investigation of the powder X-ray diffraction (XRD) of the CsPbBr3 perovskites indicates that an orthorhombic-phase structure. Our results imply that Ag+ ions serve as substitutional dopants to replace Pb2+ ions in the perovskites. Photoluminescence (PL) and absorption studies show that no major changes are made in the perovskite bandgaps, and the charging transfers are facilitated with different molecular Ag donors at their interface. This work demonstrates monovalent doping’s tunability on halide perovskites’ optical properties, shedding light toward their prospective applications in varied optoelectronic devices.

Abstract
Anthropogenic activities including uncontrolled development and agricultural intensification in the catchments area accelerate the sedimentation rate in lake and reservoir. Bukit Merah Reservoir is one of the freshwater ecosystems facing sedimentation issue and a major threat to its water quality from anthropogenic activities. These activities lead to invariably changing in water quality parameters and become the primary cause of variations to aquatic biodiversity such as zooplankton. This study investigated the biodiversity of zooplankton as a preliminary assessment in Bukit Merah Reservoir, the oldest artificial reservoir in Malaysia. Water and zooplankton samples were collected from six sampling stations which cover the littoral, limnetic and pelagic zones of the reservoir. Zooplankton analysis showed the presence of 49 taxa belonging to the three main groups of freshwater zooplankton dominated by Keratella cochlearis, Trichocerca sp., Polyarthra sp., Bosminopsis deitersi and Diaphanosoma sp. Analysis of variance revealed a significant difference was found (P<0.05) between the sampling stations during the study period. Zooplankton biodiversity reflects the water quality condition at the time of sampling that indicates the health of aquatic water body in the study site.

Abstract
The world is encountering a global threat: climate change. It is estimated that the average air temperature will raise 3.7 - 7.8 °C by 2100. The possible impacts will vary, however, agriculture will be adversely affected marked with yield loss of staple crops such as rice and maize and altered post-harvest quality of horticulture products. On the other hand, the world Food and Agriculture Organization (UN-FAO) has set a target ‘zero hunger’ by 2030’, despite the five big challenges ahead: i) protracted conflict, ii) growing inequality, iii) rapid urbanization, iv) economic challenges, v) drought and natural disasters. The existing plant genetic resources, particularly the wild, neglected, and underutilized species has a great role and bears big potential to be exploited and targetted to achieve food and nutrition security, esp. in the densely populated regions with malnutrition problem e.g. in Asia and sub-Saharan regions. However, a key to future and sustainable crop production lies in the collection of crop and their wild relatives stored in ex-situ, or in-situ. This paper aims to explain the importance of plant genetic resources as well as the potential of some underutilized crops closely attributed with drought resistence, such as sorghum (Sorghum bicolor L. Moench), amaranth (Amaranthus sp.). These crops bear potential to support national food security program.

Authors: Bukar A , Hamzah S N 
Published: March 2021

Abstract
Despite Mass Drug Administration cases of Lymphatic filariasis still exist in several developing countries such as, China, India, Indonesia, Malaysia and several Southeast Asian countries. Culex quinquefasciatus is the major vector that is dominant and widespread mosquito distributed in rural and urban areas. This study aimed at determining the diagnostic doses of LC50 and LC90 (lethal concentrations that causes 50% and 90% mortality respectively) of commonly used insecticides in Malaysia for dengue vector control by Malaysian Ministry of Health. The diagnostic LC50 of the Malathion, Pirimiphos methyl, Temephos and Deltamethrin insecticides were determined at 0.019mg/L, 0.0060 mg/L, 0.0011 mg/L and 0.0032 mg/L as well as LC90 0.033 mg/L, 0.012 mg/L, 0.0033 mg/L and 0.0010 mg/ml respectively. It is concluded that various LC50 and LC90 diagnostic doses of these insecticides were effective against the susceptible population of Cx. quinquefasciatus that also carries infective third instar larvae (L3) microfilariae. We recommend the use of these doses for effective control of Cx. quinquefasciatus population and constant monitoring of its susceptibility status will provide more information on the possible resistance that may affect the effort in the elimination of Lymphatic filariasis in affected countries.
