Abstract
Irrigation is one of the backbones in the field of agriculture. The role of technology in the industrial era 4.0 has increased tremendously in irrigation management systems. Areas, limited internet access, and validation of activity reports are separate issues in monitoring the performance of irrigation field workers in real-time. Therefore, we built a reporting system that is equipped with location tracking using the Smartphone Global Positioning System (GPS) and the Web Geographic Information System (WebGIS) application. This field reporting system starts from the report input form on the Android app that detects location coordinates automatically. Reports are stored in an offline SQLite database and sent to the MySQL database server online through the data synchronisation process. From the server-side, information displayed through the WebGIS application. This field reporting is more efficient in monitoring the performance of irrigation systems in real-time.

Abstract
The development of information technology today has been widely used to provide convenience, speed up, and streamline work. Presence system that is still applied is the type of precession using manual presence using paper media and is inefficient when viewed in terms of time, a recapitulation of data on the existence and accuracy or authenticity of the data presented. There is still often the habit of leaving a signature as proof of an employee’s presence. This study aims to provide a new model for conducting of presence, a presence system that uses RFID technology. RFID will utilize sensors to read data. The use of RFID is to facilitate lecturers and students in monitoring class attendance. On the RFID card, there is a radio frequency mounted affixed to the reading machine; the system will automatically send student data into the database. Thus, students can do it quickly, and data can also be agreed promptly and adequately. In addition, students and lecturers are also motivated to arrive early because the system can store and display data directly.

Published: April 2021

Abstract
A forest fire early warning system must be developed to reduce the impact of greater community losses. One effort to develop an early warning system is to use a forest fire hazard index as a potential assessment guide. The main factor which is a parameter in the fire hazard index calculation method is the meteorological parameter. In general, to know today’s fire hazard index is calculated from today’s weather conditions, but the need for an early warning system is to know the future fire hazard index. Based on a series of meteorological conditions data held for thirty-six months, using the backpropagation algorithm, it is estimated that the meteorological conditions will be several months to come. Several meteorological parameters have their respective roles, the unknown contribution of which is calculated. In this study, each parameter will be measured by predicting time series data and compared with the results of calculations. The method of calculating the forest fire index used is the McArthur Forest Fire Danger Index with the meteorological parameter elements are temperature, relative humidity, wind speed, and drought factor. Each parameter was trained in artificial neural networks and tested its predictions to produce accuracy for data series temperatures of 91.67%, the relative humidity of 83.33%, and wind speed of 50%.

Abstract
The development of android smartphones also plays a role in the world of education, such as the presence of android-based learning media, android-based educational information systems, and much more. If a few years ago, the academic information system was limited in the form of a website, now the academic information system has also begun to be developed on Android-based mobile devices. This is quite reasonable considering there is a myriad of advantages possessed by Android-based applications. By using an Android-based academic information system, application users can dig up information anywhere and anytime such as: Independent Lecture Schedule, Online SPP Payment (no need to queue) to fill KRS (Study Plan Card), see KHS (Study Result Card), Trusteeship, Discussions, value announcements and much more, all that can be done via a smartphone. It’s effortless, like “University Information and Communication Center in the Grip. The main advantage of developing the University Mobile Application is in terms of mobility. The application on an Android smartphone can be used anywhere and anytime. Thanks to these characteristics, Mobile Application University is the right answer to overcome obstacles in web-based or desktop-based academic information systems. With the Android-based educational information system application, information system users can access information directly from an Android smartphone. Aside from the mobility side, the development of an Android-based academic information system is also becoming increasingly optimal thanks to the smartphone’s distinctive features such as the notification feature. With the notification feature, the information will be more quickly distributed to application users. Of course, the use of an Android-based academic information system application is more effective when compared to using a web-based educational information system that must wait for users to access the web.

Abstract
English Language Teaching (ELT) is part of a teaching and learning activity focused on English development. The ELT’s distance learning enactment is used for English communication. These activities may be linked to digital literacy practices, particularly for Chinese students as non-native speakers, in stimulating English as regular communication in spoken and written centered on communication. From distance learning, some Chinese ICUTK students have contributed a lot to using English to teach and practice contact at any time. Running digital literacy practices as an ELT approach and strategy will help improve English skills in the era of Industrial Revolution 4.0, especially by enacting distance learning from China Mainland to Thailand. The purpose of this research is to know how well students can learn ELT. It describes how essential social media platforms are in delivering ELT lessons for distance learning countries between Thailand and the People’s Republic of China and how Chinese students practice digital literacy through media apps synchronously and asynchronously. This study uses a qualitative approach focused on classroom learning. Simultaneously, researchers learn how useful ELT activity for Chinese students through asynchronous and synchronous methods such as WeChat apps and Ding Talks apps. These online platforms demonstrate how effective distance learning for Chinese students in the ELT is and how useful a forum is to help teach and learn in English.

Authors: Susongko P 
Published: April 2021

Abstract
This research aims at comparing the estimation stability of participants’ abilities on scientific literacy test based on the integrated Sciences using Rasch Dichotomous Model and One-parameter Logistic Model (1-PL IRT). The research data was the responses of scientific literacy test based on the integrated Sciences involving 310 students joining the Mathematics and Natural Sciences Programs at SMA N 2 and SMA N 3 Tegal City, Indonesia. The estimation of test participants’ abilities with those two models was assisted with the eRm package and ltm package contained in the R program version 4.0.2. The next stage included analyzing mean, median, and variance of the estimation scores resulted from both models. Bootstrapping was then conducted to the parameter estimation using the new samples which have the same size with the original samples starting from 500, 800, 1000, 1500, 2000 2500, 3000 to 4000. The research result showed that the estimation of participants’ abilities in scientific literacy test based on the integrated Sciences using the Rasch Dichotomous Model was more stable than that using the 1- PL IRT seen from both bias and error standard. This means that Rasch modeling on high-stakes test assessments is more precise than using the One-Parameter Logistic Model.

Utilization of Ash from Municiple Solid Waste to Improve Physical - Mechanical Properties and Reduce of Cost Material in Manufacture of Batako
Authors: Mulyadi  , Djuhana  , Sunardi  
Published: April 2021

Abstract
Municipal solid waste processing is an important issue in every country, including Indonesia. The incineration treatment can minimize the volume of waste and produce heat and residue (ash). Ash produced can reach 10-20% of the initial volume of waste. This study was trying to reuse the ash resulted from the incineration of municiple solid waste to making of batako, which have an added value. The study of batako making used a mixture of ash from incinerators, sand and cement. Mixing composition of normal brick raw material is 25% by volume of cement and 75% by volume of sand. The addition of ash from the incinerator is done to substitute a portion of the volume of sand, which is varied as much as 10%, 20%, 30%, 40% and 50% by volume of the amount of sand used. All the raw materials were homogenously mixed and added 20% water from the total volume of material, and added 20% water from the total volume of material, then formed by pressing and followed by drying at room temperature for 14 days. The samples of batako were characterized for its density, water absoption and compressive strength. Based on the test results show that the density value tends to decrease and conversely the value of water absorption tends to increase with the increasing number of ash compositions. The concrete compressive strength value tends to increase significantly from the composition of ash 10% to 40%, but at the addition of 50% ash, the compressive strength value tends to be the same as samples using 40% ash. From the results of this study an optimal composition was obtained in a sample with 40% ash which has the characteristics of density = 1.68 g / cm3, water absorption = 18.89% and compressive strength =85.88 kgf/cm2
Accurate contact resistance characterization for thermal conductivity measurement with the Heat Flow Meter method
Authors: Fustinoni D , Vitali L , Gramazio P , Niro A 
Published: April 2021

Abstract
A common method to measure the thermal conductivity of low-conductive materials is to impose a known temperature difference across the thickness of the specimen, and to measure the resulting heat flow once steady-state conditions are reached. In particular, international standards, i.e. ASTM C518 and ISO 8301, define the characteristics of the guarded Heat Flow Meter apparatus and its measurement procedure. However, the actual measured quantity is the overall thermal resistance, which is given by the series of the contact resistance between the specimen and the temperature-controlled clamps, and the resistance of the specimen itself. Thus, the contact resistance must be correctly quantified in order to retrieve an accurate measurement. To this end, common practices are either to rely on a database of known contact resistances for material classes, or to use the “double thickness” method, which allows to eliminate the contribution of the contact resistance by carrying out the measurement on two specimens of the same material, but different thickness. While the first method is rather useless for accurate and reliable measurements, especially of unknown or innovative materials, the latter works only if the contact resistances, and therefore the surface finish, are the same for every surface of the specimen set. This paper presents an analysis of the uncertainties associated with the evaluation of the contact resistance carried out on several samples, and proposes a method to reduce such uncertainties, i.e. by inserting elastic thermal pads of known thermal conductivity between the specimen and the instrument. The results of the validation of the method are also shown, with an analysis on the improvement of the measurement accuracy for specimens with high roughness and irregular surfaces, or with conductivities beyond the instrument declared range.
