"This research aims to explore the social construction of mobile phone as a form of new media. It was conducted under constructionist perspective, employing Giddens' structuration theory to analyze the interplay between the use of mobile phone as a form of new medium, and the communication culture of millennial teenagers. Qualitative method and phenomenological research tradition are applied in this research based on the perspective of the millenniah teengers. This research concluds that even though mobile telepohone is a technological device, the use of mobile phone is a social construction, that in turn will construct values and communication culture of its users."

"The proliferation of mobile phones in developing countries has significant implications for those countries. Although numerous studies have examined the various advantages of mobile phone use, the relationship between mobile phone access and the economic welfare of households has received comparatively little attention. This paper examines the effects of mobile phone on household expenditures in 2007 and 2014 utilising the Indonesian Family Life Survey (IFLS) combined with Potential Village Survey (PODES). Ordinary Least Square (OLS), Endogenous Treatment Regression (ETR), quantile regression, and two-way fixed effect estimations are used to identify the homogeneous and heterogeneous effects of mobile phone use. According to the estimated results, mobile phone access and signal quality significantly increases household expenditure. According to the results of quantile regression, mobile phone access has the greatest effect on the upper expenditure distributions. It is highlighting the importance of promoting a policy that increases mobile phone and the supporting infrastructure on the lower expenditure distributions."

With the rapid growth of mobile phone ownership and usage worldwide, mobile phone distraction has become a real threat to pedestrians. This research aimed to examine the extent of mobile phone distraction among pedestrians. Field observations and interviews were employed to record mobile phone distractions, unsafe pedestrian behaviours, and pedestrians’ activities on mobile phones. The Pearson chi-square and Fisher’s exact test were performed to analyse the association between mobile phone distractions and pedestrian unsafe behaviours and the influence of socio-demographic factors on mobile phone distractions. In addition, Cramer’s V was employed to measure how strongly the variables are associated. The result of the research revealed that pedestrians who were looking at a mobile phone when approaching tend to not look left and right (traffic) before crossing compared to other mobile phone distractions. Moreover, texting and calling encourage pedestrians to cross outside the designated crosswalk compared to other distractions. In addition, seeing a notification was the most common activity among pedestrians that distracted them when crossing."

"Along with the development of information technology in recent era, a number of new applications emerge, especially on mobile phones. The use of mobile phones, besides as communication media, is also as media of learning, such as translator application. Translator application can be a tool to learn a language, such as English to Bahasa Indonesia translator application. The purpose of this research is to allow user to be able to translate English to Bahasa Indonesia on mobile phone easily. Translator application on this research was developed using Java programming language (especially J2ME) because of its advantage that can run on various operating systems and its open source that can be easily developed and distributed. In this research, data collection was done through literature study, observation, and browsing similar application. Development of the system used object-oriented analysis and design that can be described by using case diagrams, class diagrams, sequence diagrams, and activity diagrams. The translation process used rule-based method. Result of this research is the application of Java-based translator which can translate English sentence into Indonesian sentence. The application can be accessed using a mobile phone with Internet connection. The application has spelling check feature that is able to check the wrong word and provide alternative word that approaches the word input. Conclusion of this research is the application can translate sentence in daily conversation quite well with the sentence structure corresponds and is close to its original meaning."

Indonesia is located at the confluence of active tectonic plates, an active mountain route, thus making most of its territory prone to natural disasters from earthquakes. Based on the theory and concept of disaster management (disasters management) which includes several stages, namely: the response phase, the reconstruction and rehabilitation stage, the preventive and mitigation stage, and the preparedness stage; hence the effort to plan an earthquake early warning system must be prepared efficiently in order to reduce the resulting risks. With the development of mobile phone-based information and communication technology, information and communication is not a difficult matter, especially during disaster response. With the measured variables in the form of media warning tools, self-rescue procedures, mobilization of resources and knowledge of earthquake disasters. These variables are obtained from literature studies, then after that, the factors that compile an earthquake early warning system will be added to the application. After that, a survey was conducted to the public to determine the effect of the additional EWS (early warning system) feature of the earthquake. From the survey results that have been obtained, it can be concluded that the majority of respondents strongly agree with the average percentage of all questions above 50% that the addition of the earthquake early warning system feature can make people using the application more alert to earthquakes."

ABSTRACTMobile telecommunications network technology is the most common way to communicate, especially through Internet access. The first digital cellular technology that allows access to the internet is in the second generation (2G) called GPRS, which is the development of GSM. The need for progressive internet access is increasing. Now, fourth generation cellular technology (4G), LTE, has been commercially and massively used by the public. The evolution involves, among others, the separation of structures into access networks and core networks, the separation of protocol paths for data control and access, and addressing each element in the network based on IP addressing.

The formation of cellular telecommunications networks can be done using a computer. OpenBTS and OpenAir Interface (OAI) are an alternative to building portable GPRS and LTE cellular networks with the help of USRP B210 to implement flexible radio systems. This open source application allows modification or customization of the source code for the extension of functions in experimental evaluations. Work based on existing standards, including OAI is fully based on Release 10, allowing the formation of various components such as the EU, eNB, MME, HSS, SGW and PGW on standard Linux-based computing equipment.

The research focuses on studies to conduct comparative performance evaluations of the development of cellular technology for internet access. Evaluation includes throughput, delay, jitter, and percentage of packet loss with their respective values for GPRS, which are 62.34 KBps, 1.03 s, 433.47 ms, and 5.20% while those for LTE are 2.17 MBps, 54 , 44 ms, 12.48 ms, and 3.12%. The use of GPRS for current services such as video access and search is not possible. The percentage results of LTE quality for browsing were 69.96% and streaming was 83.80%. LTE optimizes QoS compared to GPRS up to 3492% for throughput, 1904% for delay, 3473% for jitter, and 166% for packet loss.

"Bencana alam merupakan salah satu ancaman paling serius di Indonesia. Keberadaan dua lempeng gunung aktif membuat ancaman bencana mengintai di Indonesia setiap tahun kedua. Penanggulangan bencana saat ini masih menggunakan cara tradisional yaitu turun ke lapangan dan melihat langsung titik-titik yang terkena bencana alam. Namun, situasi ini sebenarnya cukup berisiko mengingat kondisi lingkungan yang masih belum stabil sehingga cukup berbahaya bagi tim yang sedang mengamati daerah yang terkena bencana alam. Kendaraan udara tak berawak juga bisa disebut drone adalah perangkat yang beroperasi dengan cara diterbangkan secara vertikal. Alat ini sangat mumpuni untuk melewati berbagai rintangan sehingga sangat cocok digunakan sebagai pengamatan daerah yang terkena bencana. Namun, saat ini drone perlu ditingkatkan kemampuannya untuk dapat terbang secara otomatis dan mendekati objek sasaran. SURF sebagai ekstraksi ciri merupakan metode pendeteksian yang cukup ringan. Namun, kondisi bencana yang cukup kompleks memerlukan cara penyederhanaan citra agar mudah dideteksi. Di sini fitur canny edge berfungsi untuk menyederhanakan gambar dan menghasilkan deteksi yang lebih baik dan dapat diimplementasikan secara real time.

Natural disasters are one of the most serious threats in Indonesia. Existence two active mountain plates make a threat of disaster lurking in Indonesia every year the second. Disaster management is currently still using traditional methods to go to the field and see firsthand the points affected by natural disasters. However, this situation is actually quite risky considering the environmental conditions that are still not yet stable so it is quite dangerous for the team that is observing the area affected by natural disasters. Unmanned aerial vehicles can also be called drones is a device that operates by being flown vertically. This tool very qualified to pass through various obstacles so it is suitable for use as an observation of disaster-affected areas. However, currently drones need to be upgraded the ability to be able to fly automatically and approach the target object. SURF as feature extraction is a fairly light detection method. However, disaster conditions that are quite complex require a way to simplify images for easy detection. Here the canny edge feature acts for can simplify images and produce better detection and can implemented in real time.
