Published: November 2019

In 2017, Indonesia’s National Earthquake Study Center (PuSGeN) issued an updated Indonesian sources and potentials of earthquake map which shows the possibility of new earthquake hazards potentials. This triggers the assessment of building’s vulnerability towards that new earthquake hazard potential. The assessment of building vulnerability towards earthquakes is divided into two types; quick check using Rapid Visual Screening (RVS) and thorough check. In its development, RVS method was chosen because it does not require a lot of personnel, reduce time for survey, and requires lower research costs. However, RVS method that uses manual form is considered less effective for buildings with a large numbers. Nevertheless, with the existence of RViSITS android application which has developed by ITS’s RVS Team based on FEMA 154, the assessment of building vulnerability and the result can be done and accessed by all sectors quickly and easily. This article aimed to assess the vulnerability level of three high-rise buildings (8-15 floors) in East Java using RViSITS android application by comparing the result of numerical analysis based on earthquake regulations applicable in Indonesia according to SNI 1726:2012. The result of analysis using RViSITS showed that the level of vulnerability of three high-rise buildings studied is “qualified” or earthquake safe. Based on numerical analysis, it shows that the control result of base shear, mass participations, structure periods and driff control are appropriate as required by SNI 1726:2012. Generally, RViSITS can be used to map the vulnerability of high-rise buildings throughout the region in Indonesia.

Decision Making in Inventory Policy Determination for Each Echelon to Stabilize Capsicum Frutescens Price and Increase Farmers Share Value Using Discrete Event Simulation
Authors: Novitasari Nia , Setyawan E B
Published: November 2019

Capsicum frutescens is one of the vegetable commodities that can affect the dynamics of the national economy. The dynamics of the national economy is due to significant fluctuations in chili prices in Indonesia at all times. Price fluctuations occur due to lack of information either in the form of demand information or Chilean price information about consumers received by farmers for marketing red pepper. Besides, the length of the distribution of red pepper (farmer- the middleman- wholesaler- retailer- consumer) results in significant price changes from farmers to consumers at each echelon or distribution level. Such price changes result in a decline in the farmer’s share. Farmer’s share has a negative relationship with marketing margins. the negative relationship is the higher the marketing margin, the lower the share received by the farmer. from the explanation, the concept shows that the victims of the length of the distribution channel are farmers and consumers. Where farmers will bear a high business risk, and consumers will get high chili prices. The research will discuss how to stabilize the price of red pepper and improve farmer’s share by making the best decision using discrete simulation using Monte Carlo, so it can determine the supply policy by the distribution at each level aimed at reducing the operational cost. Besides, this can also reduce the hoarding activities undertaken by the relevant distribution. The hoarding can disrupt the stability of the existing chili price.

Published: November 2019

Memorizing the Qur’an is the Sunnah of Prophet Muhammad, may peace be upon him. The most crucial part of remembering the Quran is the process of learning. In general, this activity is conducted privately memorizing, one teacher for one student. One obstacle of memorizing the Quran is the limited number of teachers and many students. This private model undoubtedly ineffective. The teacher is difficult to handle the activities. Also, the teacher cannot control the student to memorize more verses because teachers must hear one by one to the student’s reading voice. Information technology has the potential benefit to innovate the learning models of memorizing the Quran. In this study, we develop a learning model using mobile technology. We design mobile learning that students can memorize independently; however teachers can still listen to reviews their reading sample, evaluate, and give guidance. The student module comes with a paragraph of verse view, including the translations. The student module also features a reading reference from international Qori. Besides that, the student module comes with a voice recording facility so students can compare with the reference reader. Teachers can assess every student until students good in reading and more verses to memorize. The primary findings of this study indicate that the teacher can handle more with better student performance. Students are highly motivated to memorize and self-evaluate their reading because they always feel under supervising by the teacher.

Degassing obscures the camera vision so that the observer barely maintain to keep track of lake phenomenon. Furthermore, even many dehazing techniques have been proposed to tackle this such problems, it still leaves some other problems such as oversaturation, color distortion, and halo effects. In this paper, a hybrid method is proposed. This work incorporates two the state-of-the-art visibility restoration and contrast enhancement methods which are color attenuation prior (CAP) and adaptive gamma correction (AGC). This method is separated into three different modules. They are disparity estimation (DispE) module, transmission map enhancement (TME) module, and hazy image restoration module (ImRec). The DispE module adapts the color attenuation model for its powerful depth estimation for handling outdoor image. Subsequently, the TME module is enhanced using AGC. And the last module is calculated from the modified hazy model. The experimental results are quite impressive. It is able to maintain edge and minimize image distortion qualitatively. And the fog density measured with Fog-Aware Density Estimation (FADE) estimated at 1.448.

The Bangil District Court is an IB class court that handles a large number of case cases. Every year more and more case cases are included in the Bangil District Court, but not all case cases are in a mutation status. By using classification techniques that can process large amounts of data to find patterns that occur in case data. Data processing is used to predict case minutation with the decision tree method using ID3 algorithm. Case data has 8 attributes and has been classified into 6 parts, namely division based on Case Type, Register, Case Classification, Length of Process, Public Prosecutor and Decision with a goal of Mutation Status. Weka 3.6 is an API that is used to build rules / rule bases. The rule that was formed was then implemented in the making of a case status prediction application in the web-based Bangil District Court.

Learning media is very influential on the interest of learning in children, especially in students. Many kinds of learning media, one of them using internet technology, computers and even mobile phones or smartphones that have a positive impact and have a negative impact. Learning media is also very influential in early childhood. Education at an early age is very important, especially for handicapped children who need more attention. Improving the effectiveness of learning should be improved to be easy to understand and not boring, then parents should improve in various ways. it includes academic education and creativity. The development of interactive multimedia learning technology allows the introduction of speech recognition technology into the application. Speech recognition is a voice command to operate a computer. Because speech recognition is a process for converting acoustic signals (sound) through a microphone as a computer operation command or writing a word (dictation). So in operation, users no longer need to use the cursor or press the keyboard. Through voice commands, users can operate the learning media..

Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus which is transmitted by Aedes Aegypty, and Aedes Albopictus (DHF) mosquitoes is a disease caused by the dengue virus transmitted by mosquitoes Aedes Aegypty and Aedes Albopictus. There are three categories of DHF with different symptoms; the first category is called Dengue Fever (DF), the symptoms of DF are characterized by fever, these symptoms are almost the same as symptoms of typhoid or Typhoid Fever (TF). The second category is Dengue Hemorrhagic Fever (DHF) symptoms of DHF characterized by fever, nausea, vomiting, red spots, and nosebleeds. The last category is dengue shock syndrome (DSS) the advanced category of DHF. To determine the level of DHF disease experienced by patients with a background of various symptoms, the DHF disease classification study was conducted using the ID3 algorithm. It is hoped that this study can help doctors diagnose DHF disease. The achievement of predictions from research using the ID3 algorithm can produce an approach in the form of symptoms that affect the level of DHF disease with an accuracy rate of 82%.
A Review on Cryptography Protocol for Securing Data
Authors: Rahim Robbi
Published: November 2019

Cryptography is one type of protection that is widely used to secure information, encryption and decryption and the use of keys is a common process used to secure information; and also the cryptographic processes have a classic problem that is the distribution of keys that are vulnerable to interception when the key is sent by the sender to the receiver, the cryptographic protocol (Authentication) could be used to minimize key distribution problem because there is no need for key exchanges. Shamir’s Three-Pass Protocol, Secret Splitting, Bit-Commitment Protocol and Blind Signature are few cryptographic protocols that can be used to help with key distribution issues, this article performs systematic approach to protocol cryptography for security level and the using other algorithms to combine with protocol.
