Gas – gas hasil pembuangan kendaraan bermotor tersebut dapat menimbulkan pencemaran dan apabila melebihi batas normal dapat berakibat buruk terhadap kesehatan manusia dan makhluk hidup disekitarnya. Semakin tinggi dan meningkatnya angka pencemaran udara maka sudah saatnya diperlukan suatu sistem yang dapat mengukur kadar kontaminan udara. Sistem ini telah dibangun dengan menggunakan mikrokontroler board Arduino Uno, sensor pendeteksi gas dan sensor pendeteksi suhu serta kelembaban udara, untuk perangkat lunaknya dibangun dengan menggunakan bahasa C Arduino, bahasa pemrograman web berbasis PHP, web server Apache, dan database MySQL. Pemanfaatan database di dalam sistem ini bertujuan untuk menyimpan data yang telah dibaca atau dideteksi oleh sensor sehingga data dapat tetap tersimpan dan dapat ditampilkan ataupun disajikan apabila dikemudian hari data pengukuran ini diperlukan.Dengan demikian informasi ini dapat dijadikan acuan sehingga dapat dihindari dampak buruk udara yang tercemar.

Ditambah lagi dengan semakin mudahnya akses internet dimana saja baik melalui perangkat mobile ataupun tidak. Karena semakin banyaknya penggunaan file audio digital oleh perorangan atau perusahaan misalnya dalam produksi musik, atau video klip maka semakin sulit untuk menentukan keaslian suatu file audio digital dan sulitnya mencegah tingkat tindak pencurian atau pembajakan yang sangat merugikan pihak pememilik hak cipta. Ada beberapa metode dalam menentukan keaslian file audio digital dan mencegah tindak pembajakan terhadap media digital, yaitu digital watermarking. Pada jurnal ini akan dibahas dua buah metode watermarking yaitu metode low bit coding dan phase coding. Tujuannya ialah untuk mengetahui beberapa kelebihan dan kekurangan dalam penerapannya kedalam file audio digital. Karena ada beberapa aspek yang harus diketahui dalam menentukan baik atau tidaknya tingkat pengamanan pada file audio digital. Sehingga kita dapat menentukan metode yang mana yang pantas digunakan dalam menentukan keaslian file audio digital dalam mencegah tindak pencurian atau pembajakan.

At present, the only explanation of this empirical phenomenon is based on a complex dynamical systems model. In this paper, we provide a simple alternative explanation. This explanation also explains – on the qualitative level – the empirical data on relative severity of different jetlags. 1 When Is the Jetlag More Severe: Empirical Facts and Their Current Explanation When is the jetlag more severe: empirical data. It is known that when we travel west-to-east, a jetlag feels more severe that after a similar east-to-west travel. A more specific data is given in [1]. In this paper, as a measure of severity of a jetlag, the authors selected the number of days that a body needs to fully adjust to the new time zone. The authors compared the recovery times for traveling 3, 9, and 12 time zones eastward and westward. These times are given in the following table: time shift recovery time recovery time west-east east-west 3 hours 4+ days 3− days 9 hours 14 days 8 days 12 hours 10 days 10 days Here, 4+ means a little more than 4 days, and 3− similarly means a little less than 3 days.","PeriodicalId":43632,"journal":{"name":"Journal of Information Technology Education-Innovations in Practice","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82993150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It turned out that the same phenomenon is true for workers working on a long-term project. However, somewhat surprisingly, for small-scale projects, the opposite is true: teams without any prior collaboration experience are more successful. Moreover, it turns out that if combine in a team members with prior collaboration experience and members without such experience, the efficiency of the team gets even lower. In this paper, we provide a possible explanation for this strange empirical phenomenon. 1 Formulation of the Problem In education, permanent (or at least stable) teams are more efficient. In the education environment, empirical data shows that when students form stable long-term teams to study together, the results are much better than when form temporary team for each class or even for each assignment; see, e.g., [2, 4]. This is not just an empirical fact: there are theoretical explanations for this phenomenon; see, e.g., [3]. Surprisingly, in industry, sometimes temporary teams are more efficient. Based on the results of education-related studies, one would expect that in industry, similarly, stable teams should be more efficient.","PeriodicalId":43632,"journal":{"name":"Journal of Information Technology Education-Innovations in Practice","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90181702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
