Solar dryer is typically used for agricultural purposes in Indonesia. There are many economically important crops requiring storage or drying under particular environmental conditions such as temperature and humidity. High temperatures inside solar dryer prevents the growth of microorganism, and quickly reduce moisture content from the substance. A hybrid solar dryer is generally considered to provide the most optimum solution, however solar panels may be expensive and they still only provide heat or energy in the daytime. Hence, we propose here a new kind of hybrid solar dryer for 24/7 optimum conditions for crops - enabled by recent advances in energy technologies as well as Industry 4.0. This study aims to create an efficient, affordable and a self-sufficient intelligent energy system that will be applied to agriculture for storage or drying purposes by measuring the energy needs for the optimal drying system. Therefore, it is crucial to estimate and assess the critical energy needs for such new systems in order to optimize and design such smart solar dryer (SSD) system especially for Indonesia's agricultural needs. We use design experience of our industry partner (PT Impack Pratama Industri, Indonesia) who has been working extensively on such solar dryer dome (SDD) based on polycarbonate material (only solar irradiation, no other technologies) and theoretical framework based on first principles in thermodynamics to estimate and assess critical energy needs for such dome with all the smart technologies. The calculation was performed based on Mollier diagram and the result still a rough estimation of energy required.

This research aims at examining the comparison of Different Solvent Extractions on antidiabetic activity tests of Cassia *** leaf. It conducted in vitro using the α-glucosidase enzyme and maceration technique with ethanol concentration of 70% and 90%. In this case, each ethanol extract was fractionated using ethyl acetate and hexane. The results of the t test statistic are greater than t table of 2.262 and the Sig value is smaller than α of 0.05. Therefore, It found that the difference in average antidiabetic activity for 70% and 90% concentrations in ethanol, ethyl acetate and hexane fractions produced positive values. However, the two ethanol concentrations differ in producing an average antidiabetic activity. Finally, the research concluded that the antidiabetic activity of *** leaf extract with an ethanol concentration of 70% is better than ethanol concentration of 90%.

We introduce a composition of object-oriented component PHP grammar for taint analysis. Our novel method successfully restructured the PHP parser and reduced grammar artifact objects that must be visited in a taint analysis process by up to 52% grammar variation. Taint analysis is an analysis that detects any injection vulnerability pattern in source code. The analysis identifies the information flow of untrustworthy input that affects the sensitive sink or part of the system. The static taint analysis was run on an abstract syntax tree and traversed all nodes. A static taint analysis uses a parser to traverse abstract syntax trees of the source code. A web PHP parser has 140 grammar combinations in an abstract syntax tree, which has to be traversed to recognize the tainted flow pattern. Additionally, there are many variations of syntax and coding styles for tainted flow patterns. Therefore, the amount of combinations will consume many computation resources. © 2018 The Authors.

Power plant is one of the substantial industry in a country since it supports various needs of people. Optimum cost for running this industry is a necessity so that power generated can be produce according to power demand with appropriate cost. Economic dispatch is an optimization approach in power system plant with objective function is to minimize cost by finding appropriate arrangement of generator output according electric requirement and capacity of the system. Previous researches have been proposed techniques to solve this problem, however a stable convergence and good computational efficiency is still required. Therefore, this paper proposes bat algorithm to minimize total generator cost from thermal power plant. Bat algorithm is one of nature inspired optimization problem which has advantage in stable convergence. The experiment results show that Bat algorithm is able to save approximately 1.23% compare to the actual cost and 0.12% to firefly algorithm. © 2018 The Authors. Published by Elsevier Ltd.

Bridge traveler is used to facilitate the construction and maintenance of a bridge which is controlled using control panel buttons, located inside the traveler. However, this method leads to some problems, like a difficulty of moving a traveler to a proper position (perspective) and an inhibition of work due to damaged control panel. In this research, a model of a web-based application to control a traveler with spans by using Raspberry Pi is developed. This research's contribution is a model of a web-based application for traveler automation in all possible movements of its components. As the results, the experiments show that the program implemented doesn't take much time and the execution of a command is done in a reasonable time. Moreover, for the safety of the bridge traveler, this program also implements a sensor that works when a component is at its most downward/inward position and detecting a blocking object in the middle of a possible movement and stops the movement immediately. © 2018 The Authors.

This paper presents our research on Indonesian question answering system for solving arithmetic word problems using pattern matching approach on intelligent humanoid robot. The objective of this paper is to elaborate how natural language processing (NLP) and pattern matching approach works in question answering system for solving arithmetic word problems. Upon receiving a Indonesian arithmetic word problem, the robot will translate Indonesian speech to English text, resolve conjunction problem, co-references problem, question preprocessing, question analysis, represent the knowledge, and lastly the robot will answer the solution. We employed NLP for English by using Natural Language Toolkit (NLTK) in our research. Based on the experiment results, it can be concluded that: (i) the accuracy of the question answering system for each scheme ranges from 80% to 100% depend on the difficulty to comprehend the word problem, (ii) the response time is rather slow with average processing time is about 1.12 minutes. © 2018 The Authors.

The paper presents the classification of brainwave response based on low-cost Electroencephalograph (EEG) spectrogram. The low-cost EEG can record EEG data, but it performs significantly worse than the medical device. The purpose of our research is to understand the way of images are perceived by people based on their brain waves. Based on the EEG, we investigate two paradigms in mind-brain research that is: the valence-arousal plane and the universal symbol. The experiments are done using two paradigms to generate EEG data based on visual stimuli and convert it into spectrogram. For brainwave response classification based on EEG spectrogram, we use the recent deep learning architecture that is DenseNet. Furthermore, we compare the training performance between two brain-mind paradigms. The experiment results show that: (i) the EEG signal classification of visual stimuli based on valence-arousal model framework is not reliable, (ii) the universal symbol paradigm gives a promising result in generating visual stimuli for brainwave response classification based on low-cost EEG data. © 2018 The Authors.
