Authors: C Karthik
Published: January 2019

Blockchain Technology is an emerging technology nowadays. The Blockchain was first used as a Peer-to-Peer ledger for registering Bitcoin transactions. The blockchain is a singly linked list which consists of a number of transactions. The blockchain is a decentralized distributed ledger which consists of a number of blocks organized in the form of a chain. A block in blockchain consists of two parts data and hash pointer. The first block in the blockchain is known as genesis block. The transactions and data in the block are secured by cryptography. The data inside a block in blockchain can be anything like bank transactions, backup data etc., which are recorded chronologically and publicly. The Hash pointer of a block is a unique code generated by a hash function like SHA256, SHA-3 etc., the hash function used in bitcoin blockchain. A block consists of a public key and a private key, using hash function digital signature is generated to the block. This is how the data inside the blockchain is so secured. The blocks are added into the blockchain by verifying the transaction in the block, the transactions are verified by miners. The miners use consensus algorithm to solve the blocks.

Abstract : Suspended footbridges has a lot of constructed in Indonesia to access many–especially rural-regions. Due to its flexiblity, understanding and design of the suspension bridge is not enough to rely on static analysis. This paper deal with the dynamic behaviour of simply unstiffening suspended bridges subjected to pedestrian load and motor-cycles moving load.As the SNI 03-3428-1994 codeof the technical planning for pedestrian suspension bridge is not set in consideration of dynamic analysis and design,pedestrian-load model is based on British Standard BS 5400-4: 1990 and Eurocode EN1991-2:2003. Modeling pedestrian load is done in three conditions; single pedestrian, group, and crowd. The motor-cycles moving load is modeled as a moving force model, accurate for low speed. Variations in the speed used was 10 km / h, 20 km / h, 30 km / h are considered representative. Dynamic analysis done by the time history Newmark direct integration method with the help of finite element analysis program SAP2000 v.15. Span 60 m, 80 m and 100 m was studied. As these results, dynamic interaction between the bridges and pedestrian load is not significant.The analyses have shown that the responses greatly differ between the British Standard and Eurocode.However, motor-cycle load has same results but higher  with the largest DAF value 7.27% for speeds of 30 km / h interval of 2 seconds on a span of 100 m. Abstrak: Jembatan gantung pejalan kaki telah banyak sekali dibangun di Indonesia, sebagai pemecah masalah akses antar wilayah. Dikarenakan strukturnya yang fleksible, pemahaman dan desain jembatan gantung tidak cukup sekedar mengandalkan analisis statis. Tujuan penelitian ini adalah untuk memperlihatkan respons dinamis jembatan gantung pejalan kaki sederhana tanpa pengaku. Hal yang akan dipelajari adalah simpangan vertikal dan percepatan ditinjau dari sisi kenyamanan. Beban yang dikenakan adalah beban pejalan kaki dan kendaraan roda dua. Dikarenakan SNI 03-3428-1994 Tata cara perencanaan teknik jembatan gantung untuk pejalan kaki tidak mengatur analisis dinamis dalam pertimbangan analisis dan desain, pemodelan beban pejalan kaki didasarkan pada British Standard BS 5400-4:1990 dan Eurocode EN1990. Pemodelan beban pejalan kaki dilakukan dalam tiga kondisi; pejalan tunggal, pejalan kelompok, dan arus keramaian. Untuk beban kendaraan dimodelkan sebagai beban berjalan yang cukup akurat untuk kecepatan rendah. Variasi kecepatan yang digunakan adalah 10 km/jam, 20 km/jam, 30 km/jam dianggap cukup representatif. Analisis dinamis dilakukan secara riwayat waktu dengan metode integrasi langsung Newmark dengan bantuan program analisa elemen hingga SAP2000 v.15. Bentang yang diteliti adalah 60 m, 80 m dan 100 m. Dari hasil tersebut didapati bahwa percepatan akibat beban pejalan kaki masih kecil sehingga tak berpengaruh secara signfikan. Sedangkan beban sepeda motor juga demikian, dengan nilai DAF terbesar 7,27 % untuk kecepatan 30 km/jam selang 2 detik pada bentang 100 m.

This paper aims to study whether the zone will change the street users’ behavior and vehicles reduce speed when going through the school zone. The research uses Z-score testing method from norm standard distribution for ZoSS application requirements. The test is done in 8 (eight) roads in front school yard with no school zone facilities. Furthermore, one school is selected to develop minimum ZoSS facilities. The evaluation of the street users from both conditions (with and without ZoSS) shows changing from unsafe to safety. That means the ZoSS gives a positive changes to the street users behavior.Keywords : Behavior, Safety, School, Speed, Street Users, ReduceAbstrak: Zona Selamat Sekolah (ZoSS) adalah ruas jalan di depan sekolah yang mengatur kendaraan yang melewatinya harus mengurangi kecepatan berbasis waktu, dan kemudian peraturan itu enjadi aturan etika bagi pengguna jalan. Namun demikian, masih banyak pengendara yang tidak memahami etika tersebut. Kota Langsa adalah salah satu Kota di Provinsi Aceh yang menerapkan sistem Kota Administrasi sejak tahun 2001. Kota ini terus berkembang di berbagai sektor, termasuk dalam pembangunan infrastruktur transportasinya. Akan tetapi ZoSS masih belum diaplikasikan secara optimal sehingga tidak terlalu dikenal oleh masyarakat. Artikel ini bertujuan untuk mempelajari apakah jika ZoSS diterapkan di Kota Langsa ini akan merubah perilaku pengendara yang lewat di depan sekolah dengan mengurangi kecepatan kendaraannya atau tidak.

Abstract: Crashing  project duration is conducted when the project experience schedule delay. The consequence of this crashing is needed the additional cost to anticipate the delay. Choosing the right activity for the reduction will provide additional cost efficiency. The purpose of this research is to develop time-cost trade-off (TCTO) model for tie beam activity. The model was developed based on the respondent's perception through the questionnaire, and collecting the Budget Plan Report. Respondents in this study are director, estimator, and project manager at contractor who is domiciled in West Aceh District. The results showed that the tie beam can be broken down into sub activities such formwork, rebar and concrete that have different characteristics in tie beam activities based on TCTO model. Based on these conditions, the sub activities activities can be accelerated from the normal duration of the project are 60%, 50% and 60% respectively and the required additional cost is 2.88% per day, 2.93% per day, and 3.88% per day.Keywords : Project Crashing, Crash Duration, Additional cost, Model TCTO, Tie beam, West of Aceh, Formwork, Rebar work, Concrete workAbstrak: Percepatan schedule sering dilakukan ketika kemajuan proyek dinilai mengalami keterlambatan terhadap rencana awal.

Exploring Challenges of Assessment in Engineering Problem Solving, A Thematic Analysis
Authors: Memarian Bahar , McCahan Susan
Published: January 2019

Through a thematic analysis of open-ended survey responses, we explore the challenges assessors face during assessment (summative evaluation and formative feedback) of students’ work. The assessors were primed by asking them to mark solutions to closed-ended engineering problems typical in introductory Electrical and Civil engineering courses. The subsequent survey asked the assessors to reflect on their experience. The analysis of the thematic frequency count is presented and discussed in this paper. The data suggests that from the perspective of assessors, current assessment practices need improvement. In particular, it appears that summative evaluation is seen as the primary goal and feedback is given as time allows. However, the participants also identified insufficient time as a challenge, which may further diminish feedback

Creative and innovative people are recognized for their contribution to society’s wellbeing. Engineers are often called upon to produce innovative ideas and thus participate in the improvement of their organization’s products, services, and processes. Not aiming at educating specialists with a degree in creativity, we nonetheless believe future engineers could benefit from a deliberate development of their creative abilities. However, building an effective and valid course to develop participants’ creativity is not without challenges.This paper describes an innovative cognitive approach to enhance creativity as well as the pedagogical strategies underlining a creativity course for engineering students. It also presents the pre-post results measured with a revised version of the CEDA (Creative Engineering Design Assessment). We evaluated the creative performance of 59 students before and after a 45-hour creativity course. Quantitative data shows statistically higher numbers after the course than before. Qualitative data provides further evidence of the course’s relevance and effectiveness.We conclude that students’ creativity can be increase and that the course enables a better understanding of creativity and how to foster it.

The ability to work in teams is an important learning outcome for graduating engineering students. There are, however, limited intentional and structured teaching opportunities through which engineering faculty can instruct students on effective team behaviours.In this paper, we describe a workshop in which student teams self-assess and create a plan to improve their team processes. Students first complete individual surveys, reflecting on their perceptions of the effectiveness of their teams. Individual responses are then aggregated at the team level, with each team receiving summary team scores. A structured in-class activity provides teams with an opportunity to reflect on effective and ineffective team processes, share strategies and best practices with other teams, and develop plans for improvement.Multiple deliveries of the module in various engineering programs, including in a capstone design course, have shown that the module is an effective tool for teams to self-assess and self-correct.

To safeguard the environment and satisfy the energy needs of the present, without compromising the ability of future generations to do the same, sustainable energy development is urgently needed. This complex task is riddled with social, political, scientific, technical, and environmental challenges. Education is essential if we are to meet the energy demands of the world in the most sustainable manner available to us. Langara College offers a first-year engineering course that is meant to introduce students to engineering design and case studies, in addition to providing a brief glance on the history, ethics, and the different disciplines of engineering (APSC 1010–Engineering and Technology in Society). This paper demonstrates how this, or similar courses are optimized to raise awareness of the sustainability issues this planet is facing.Using a project-based learning approach that promotes teamwork and research, this course uses a variety of instructional methods including lectures, class discussions, and guest appearances by experts in their fields. Introductions to technical concepts, such as soldering, 3D printing, and microcontroller, are also addressed. The course culminates in a group project in which students are encouraged to select and research an issue on sustainable development. Several topics, which has already been briefly covered by the curriculum, include population, ecosystem, energy, and water.
