Indeed, there are great market potential of Aloe vera (L.) Burm.f. (Ghrit-kumari) due to their medicinal and cosmetic values. However, the serious problems faced by farmers related to supply of harvested leaves materials after cultivation for industrial extraction and production of juice under a short and specific time of transportation to avoid spoil of materials and protect from decayed condition of leaves. Hence, the cultivation practices of the plant are not being popular although the utilization of leaves by pharmaceutical companies is gradually increasing. To solve the above problems, an analysis on extraction of pulp from leaves and preparation of juice in a small scale level has been carried out useful for the farmers and medicinal plant growers for processing of leaves at plantation site. It has been observed that after harvesting of leaves the boil or warm water is useful to process the leaves for pulp extraction in cold season. The standard percentage of activated charcoal observed in processing of pulp for removal of pigments varies from 12-15 gm/ kg according to pulp. The processing in homogenization, filtration and better preservation and stability of juice different ratio have been analyzed for keeping in good condition up to 180 days and above and the requirement of EDTA is 0.9-1.2gm/kg of pulp. The citric acid required 1.1-1.3 gm/kg for better and good condition of juice. The maintenances of PH of processed material various composition of different preservatives have been assessed. Effects of natural preservatives like lemon and honey to protect juice up to 30 days has been studied and found at least 10:5 ml/100ml respectively in closed container under good storage condition.

Test Result

One of the challenges of teaching English for Science students in Indonesia is the training to comprehend science content in English. They need to have the skill to improve their science development knowledge by exploring it through latest information from scientific journals and text books. In fact, most of the students have limited English proficiency that results in the limited variety source of their literature references. Their pre-test result was not satisfactory by only reaching the average of 67. To overcome the problem, the workbook that integrated English skill and science content was developed to support the learning process. The design of research was Research and Development consisting of conducting need analysis, designing product, expert validation, revising product, trial in small scale level, and using the product in the learning process. The instrument to gather the data was the validation sheet for the expert containing indicators of valid criteria of workbook from the aspect of the material, language and media, the students' response questionnaire related to the use of workbook and science content in English test. The data were analyzed descriptively based on the data obtained from the research. The validation from the experts of language, material and media to produce a valid and feasible product showed that the workbook was feasible to be used as instructional material. The result showed that the expert of material, language and media gave the score of respectively 100, 92 and 92. The workbook also proved to be effective to improve the students' mastery of science content in English material with the average of 80. The workbook entitled Science plus English was designed to revise the previous instructional material and it has never been developed as instructional material. The novelty is the integration of English skill lesson and science content.

AbstractBackgroundMetabolic network models are increasingly being used in health care and industry. As a consequence, many tools have been released to automate their reconstruction process de novo. In order to enable gene deletion simulations and integration of gene expression data, these networks must include gene-protein-reaction (GPR) rules, which describe with a Boolean logic relationships between the gene products (e.g., enzyme isoforms or subunits) associated with the catalysis of a given reaction. Nevertheless, the reconstruction of GPRs still remains a largely manual and time consuming process. Aiming at fully automating the reconstruction process of GPRs for any organism, we propose the open-source python-based framework GPRuler.ResultsBy mining text and data from 9 different biological databases, GPRuler can reconstruct GPRs starting either from just the name of the target organism or from an existing metabolic model. The performance of the developed tool is evaluated at small-scale level for a manually curated metabolic model, and at genome-scale level for three metabolic models related to Homo sapiens and Saccharomyces cerevisiae organisms. By exploiting these models as benchmarks, the proposed tool shown its ability to reproduce the original GPR rules with a high level of accuracy. In all the tested scenarios, after a manual investigation of the mismatches between the rules proposed by GPRuler and the original ones, the proposed approach revealed to be in many cases more accurate than the original models.ConclusionsBy complementing existing tools for metabolic network reconstruction with the possibility to reconstruct GPRs quickly and with a few resources, GPRuler paves the way to the study of context-specific metabolic networks, representing the active portion of the complete network in given conditions, for organisms of industrial or biomedical interest that have not been characterized metabolically yet.

The production of sugarcane is increasing in Nigeria nowadays. Juice extracted from sugarcane can be used extensively in manufacturing brown sugar, industrial sugar and bioethanol fuel through the process of fermentation; hence, the need to develop a machine that can extract juice from sugarcane effectively. This work involves the design, fabrication and performance evaluation of sugarcane juice extractor. The machine was designed to extract juice from sugarcane at small scale level suitable for small and medium scale sugarcane processors. The prototype machine was designed, fabricated and assembled in the Department of Agricultural and Bio-resources Engineering, Ahmadu Bello University, Zaria. The machine consists of rollers, gears, cane guide, juice collector, frame, and prime mover. The developed machine was evaluated using koma variety of cane and obtained an output capacity of 148.2 kg/h and extraction efficiency of 67.44%, respectively at a speed of 30 rpm. The production cost stood at N 90,000 which is affordable and therefore recommended for small scale processors.

Net Cage

Aquaculture is growing rapidly in Banjar District of Kalimantan Selatan Province, including on Riam Kanan Reservoir which is a center for floating net cage aquaculture. The increasing aquaculture on Riam Kanan Reservoir is not supported by adequate and actual data regarding the distribution, number of plots and number of fishery household (FHs) of floating net cage aquaculture. Complete, accurate and actual data is needed as one of the considerations in implementing sustainable aquaculture management policies. This study aims to map the distribution of floating net cages based on zones and business scale level, analyze the number of plots and the number of FHs of floating net cage aquaculture on Riam Kanan Reservoir. The study was conducted in July-October 2019 using 2 survey methods: a drone survey to collect aerial photographs and a field survey to identify the number of FHs and floating net cage plots based on business scale level. The results of aerial photography were analyzed using the Agisoft Metashape Professional and Arcgis 10.7 applications. Field survey data were analyzed using the Archgis 10.7 application and Microsoft Excel. The floating net cage is spread over 6 zones totaling 4,263 plots, consisting of criteria for small business scale 1,774 plots, medium scale 1,234 plots and large scale 1,255 plots. FHs of floating net cage aquaculture spread in 7 villages as many as 425 units with the criteria of 331 small scale business, 87 medium scale and 28 large scale. The plots and FHs of floating net cage aquaculture on Riam Kanan Reservoir has increased significantly over the past 4 years.
