"A significant and convenient approach to detection and analysis of biological, environmental and agricultural items is the harnessing of features in widely available smartphones to create field-deployable scientific instruments, allowing measurements to be made onsite and in real-time. This book will cover a number of self-contained smartphone instruments with the particular focus on spectroscopic-based measurements. Measurement and analysis on precision of such low-cost instrumentations are provided to compare with more expensive commercial equipment.This book also discusses some limitations, possible recommendations and scopes for further instrumentations using smartphones and other smart devices. Particularly, the opportunity to integrate the devices into the global Internet-of-Things (IoT) platform will be discussed. Researchers and instrumentation designers in optical and photonic sensing, smart and IoT-based sensing, biological and environmental analysts, agricultural, and food quality researchers (and public health authorities) will find this book useful as reference. Students in science and engineering disciplines for teaching and educational purposes will also find this book useful as a secondary textbook."

"Penelitian ini bertujuan untuk mendapatkan gambaran postur yang berisiko penggunaan smartphone pada mahasiswa sarjana reguler di FKM UI tahun 2019. Selain itu, penelitian ini juga melihat gambaran faktor individu dan faktor pemakaian terhadap keluhan subjektif gejala gangguan otot rangka dan gejala gangguan mata kering pada mahasiswa pengguna smartphone. Desain penelitian ini adalah cross sectional. Penilaian postur berisiko dilakukan melalui observasi pada mahasiswa pengguna smartphone (n = 30) yang diukur dengan metode REBA dan dibandingkan dengan literatur yang ada. Gambaran faktor individu, faktor pemakaian, keluhan subjektif gejala gangguan otot rangka, dan gejala gangguan mata kering didapatkan dari pengisian kuesioner oleh mahasiswa pengguna smartphone (n = 204). Hasil penelitian menunjukkan postur yang paling berisiko saat menggunakan smartphone antara lain postur leher (71,4%) dan lengan bawah (59,5%). Kebanyakan responden (82,4%) selalu menghabiskan > 7 kali dalam sehari per kesempatan untuk menggunakan smartphone dan 89,2% responden menggunakan smartphone secara berlebihan selama > 2 jam/hari. Lebih dari sebagian mahasiswa (64,7%) memiliki keluhan subjektif ringan sampai parah pada mata dalam 7 hari terakhir. Keluhan subjektif gejala gangguan otot rangka yang dirasakan mahasiswa dalam 7 hari terakhir pada tiga bagian tubuh terbanyak adalah leher (59,3%), bahu/lengan atas (50,0%) dan punggung atas (44,6%).

The aim of this study is to get an overview of posture at risk while using a smartphone among PH UI regular undergraduate students in 2019. This study also looks an overview of individual factors and usage factors for subjective complaints of musculoskeletal symptoms and dry eye symptoms in smartphone users. The design of this study was cross sectional. Assessment of posture at risk is done through observation on smartphone users (n = 30) as measured by the REBA method and compared with existing theories. The description of individual factors, factors of use, subjective complaints of musculoskeletal symptoms, and dry eye symptoms were obtained from filling out questionnaires by smartphone users (n = 204). The results showed that the most posture at risk while using a smartphone include neck (71,4%) and forearm (59,5%) posture. Most respondents (82.4%) always spend > 7 times a day per chance to use a smartphone and 89.2% of respondents use smartphones excessively for > 2 hours/day. More than half of students (64.7%) had mild to severe subjective complaints in the eyes in the last 7 days. Subjective complaints of musculoskeletal symptoms in the last 7 days were neck (59.3%), shoulder/upper arm (50.0%) and upper back (44.6%)."

"Di era modern ini, fenomena penggunaan smartphone di perkotaan semakin meningkat. Masyarakat modern tidak hanya menggunakan smartphone sebagai alat komunikasi tetapi juga sebagai alat untuk mempertahankan ruang personalnya dari orang asing di ruang publik. Skripsi ini mengkaji penggunaan smartphone dengan pola pertahanan diri terhadap orang asing di ruang publik. Pengamatan dilakukan menggunakan metode spasial etnografi di peron stasiun Manggarai dan Universitas Indonesia. Hasil pengamatan menunjukkan bahwa penggunaan smartphone meningkatkan keterasingan antarindividu masyarakat kota. Penulisan ini bermanfaat sebagai pertimbangan bahwa perancangan ruang publik harus dapat menanggapi perkembangan teknologi dan perubahan budaya berkota.

In this modern era, the phenomenon of smartphones usage is increasing in urban area. Modern society does not only use this as communication tools but also as a self defense to defend its personal space from strangers in the public space. This undergraduate thesis examines the smartphones usage with self defense patterns from strangers in the public place. Observation was conducted by using spatial ethnography method at the platforms of Manggarai and Universitas Indonesia train stations. The observation shows that the usage of smartphones intensifies alienation of urban society. This study may serve as future considerations that the design of public space should be able to respond current technological developments and urban cultural changes."

"This SpringerBrief investigates and reviews the development and various applications of mobile crowd sensing (MCS). With the miniaturization of sensors and the popularity of smart mobile devices, MCS becomes a promising solution to efficiently collect different types of information, such as traffic conditions, air quality, temperature and more, which is covered in this brief. The features, novelty, and applications of MCS are elaborated in detail in this brief. In addition, the basic knowledge about auction theory and incentive mechanism design is introduced.Incentive mechanism design plays a key role in the success of MCS. With an efficient incentive mechanism, it is possible to attract enough mobile users to participate in a MCS system, thus enough high quality sensing data can be collected. Two types of incentive mechanisms with different system models are introduced in this brief. One is the reputation-aware incentive mechanism, and another is the social-aware incentive mechanism.This SpringerBrief covers the significance and the impacts of both reputation and social relationship of smartphone users (SUs) in MCS and presents extensive simulation results to demonstrate the good performance of the proposed incentive mechanisms compared with some existing counterparts.The target audience for this SpringerBrief is researchers and engineers in the area of wireless communication and networking, especially those who are interested in the mobile crowd sensing or incentive mechanism design. Meanwhile, it is also intended as a reference guide for advanced level students in the area of wireless communications and computer networks."

"This book provides insight and expert advice on the challenges of Trust, Identity, Privacy, Protection, Safety and Security (TIPPSS) for the growing Internet of Things (IoT) in our connected world.

"Skripsi ini membahas mengenai kejadian penggunaan ponsel pintar berlebih yang ada pada mahasiswa program sarjana Fakultas Kesehatan Masyarakat Universitas Indonesia pada tahun 2020. Penelitian ini merupakan penelitian kuantitatif dengan desain studi cross-sectional. Penelitian ini dilakukan pada bulan Juni-Juli 2020 dengan total sampel sebanyak 241 mahasiswa. Dari hasil penelitian ini, ditemukan bahwa beban kerja akademik, kesadaran diri, penggunaan ponsel pintar untuk membuka sosial media serta belanja online, dan durasi penggunaan ponsel pintar dalam sehari memiliki hubungan yang signifikan dengan kejadian penggunaan ponsel pintar berlebih. Karenanya, peneliti menyarankan kepada Kementerian Kesehatan untuk memberikan informasi serta edukasi kepada masyarakat, terutama kelompok remaja dan dewasa muda mengenai penggunaan ponsel pintar yang bijak dan sehat secara fisik dan mental.

This thesis discusses the excessive smartphone usage phenomenon that existed within undergraduate students of the Faculty of Public Health at University of Indonesia in 2020. This research is a quantitative study that used the cross-sectional study design that was conducted in June-July 2020 with a total sample of 241 students. The results of this research concluded that academic workload, self-awareness, use of smartphone to open social media and online shopping, and duration of smartphone use in a day are significantly related to excessive smartphone usage. Therefore, the researcher suggests for the Ministry of Health to provide information and education to the public, especially adolescents and young adults, about ways to use the smartphone wisely and healthily."
