Authors: Lone Irfan H. , Aslam Jeenat , Radwan Nagi R.E. , Akhter Arifa , Bashal Ali H. , Shiekh Rayees A. 
Published: December 2019

Background:
he properties of materials depend on the way of construction and the arrangement
of atoms and molecules. Therefore, it is very important to know synthesis methods for the
preparation of novel materials as per their desired structure. The low-temperature synthesis methods,
such as polymeric citrate precursor and sonochemical methods are efficient enough to control the
preparation of novel nanoparticles with morphological differences that leads to the novel devices
with desired technological performances. These methods are simple, very less expensive and are easy
to handle to operate for the synthesis of nanoparticles as per the expected morphology and dimensions.

Methods:
Polymeric citrate precursor method, a chelate-based method involves the reaction between
mixed cations with citric acid, and then these cations are cross-linked with the help of ethylene glycol
for the esterification process. Gel composites were heated which burns the organic moieties leaving
behind the nanoparticles, and burning gels becomes essential for the reduction of nanoparticles. The
sonochemical method, on the other hand, uses ultrasonic the irradiation results. The acoustic cavitation
and high intensity ultrasound has been exploited for the preparation of different series of nanoparticles.

Results:
Commonly known for polymeric citrate method as Pechini gel pyrolysis method gives the
evidence of versatile and elegant method for the synthesis of nanoparticles. The sonochemical method
provides an unusual route of nanoparticle fabrication without bulk and that too with low temperature
and pressure or less reaction time. These two methods have better control for the desired shape
morphology and size and provide many opportunities for the use of these prepared nanoparticles in
various aspects of science and technology.

Conclusion:
Polymeric citrate precursor and sonochemical methods are efficient to reduce to promote
desirable reaction conditions and reduce the metal ions for the fabrication of nanoparticles. The
prepared nanoparticles by using such low-cost elegant methods are uniform with a small size distribution,
reproducible with good yield as per the demanded applications.

Published: December 2019

Background:In 21st century one of the emerging issues is to secure the information stored and communicated in digital form. There is no assurance that the data we have sent may be hacked by any hacker and the data we have sent may reach correctly to the receiver or not. Thus, confidentiality, integrity, and authentication services play major role in Internet communication. Encryption is the process of encoding messages in such a way that only authorized parties can read and understand after successful decryption. Several data security techniques have been emerged in recent years, but still there is a need to develop new and different techniques to protect the digital information from attackers. This paper provides a new idea for data encryption and decryption using the notion of binary tree traversal to secure digital data.Objective:To develop a new data encryption and decryption method using the notion of binary tree traversal to secure data.Methods:The proposed method uses both transposition and substitution techniques for converting plaintext into ciphertext. The notion binary tree in-order traversal is adapted as transposition and Caesar cipher technique for substitution.Results:From the result, it observed that the repeating letters in the plaintext are replaced with different cipher letters. Hence, it is infeasible to predict the plaintext message easily using letter frequency analysis. From the experimental result, it is concluded that the proposed method provides different ciphertext for the same plaintext message when the number of round varies. The time taken by the proposed method for encryption is very less.Conclusion:A simple encryption method using binary tree in-order traversal and Caesar cipher is developed. Encrypting data using binary tree traversals is a different way while compared with other traditional encryption methods. The proposed method is fast, secure and can be used to encrypt short messages in real time applications.

IMPLEMENTATION OF RELIGIOUS VALUES ON INDIVIDUAL EDUCATION PROGRAM (IEP) BASED IN ISLAMIC ELEMENTARY SCHOOL
Authors: Kurniawan Redite 
Published: December 2019

Elementary has emerged as an inclusive school in Indonesia recently. Eventhough some of them haven’t shown the proper planning of inclusive learning, learning process, and optimal outcome learning for special needs students. Moreover if the learning process connected with religious value in Islamic elementary school. How the implementation of religious value can be involved in Individual Education Program (IEP) in elementary school? This paper discuss about Individual Education Program (IEP) based on religious value which conduct as a particular curriculum for special needs students (SNS). Investigation for specific purpose on this study headed to Islamic values development in SNS. The data collected from interviews, documents, and observation from Ar-Roihan Inclusive Islamic Elementary School Lawang that has been pointed as inclusive pilot project since 2016. Prior study has shown the benefit of inclusive school for disability children, but it’s not focus on how Islamic values influence in their daily activities. Developed from data collected, the IEP program has reflected how the SNS used to and motivated to Islamic way in their daily activities, such as pray together, recite holy Qur’an, and respect for each other. Findings indicated that IEP which had given as individual treatment and lesson plan became an important thing for Islamic inclusive elementary school to reach their goal for disability students activities such as pray together, recite holy Quran, dan giving charity.
