Abstract

Abstrak: Aquascape adalah sebuah seni yang mengatur tanaman air, batu, karang,kayu dan lain-lain sebagainya.Seni ini menggunakan media didalam kotak kaca atau akrilik yang menyerupai aquarium.Dalam merawat tumbuhan-tumbuhan yang berada didalam Aquscape itu hidup tergantung pada temperatur air. Pengujian ini dibuat alat uji menggunakan dua buah termoelektrik sebagai pendingin sedangkan water block alumium sebagai penampung air sementara untuk didinginkan dan dipindahkan kedalam aquascape. Adapaun tujuan penelitian ini untuk mengetahui berapa suhu temperatur air yang sesuai pada tanaman yang berada di dalam aquascape. Nilai perpindahan panas konduksi yang terjadi dalam pengujian menggunakan dua buah termoelektrik yang disusun sejar adalah 1,1211 Watt.Kata kunci: aquascape, termoelektrik, water block aluminium, perpindahan panas konduksi

Abstract

In entering the modern era and the rapid development of technology today, people are familiar with increasingly advanced and affordable technology to make it easier to carry out various activities in life. Technological progress is very rapidly occurring in various fields, for example in the fields of transportation, communication, health, education, and other fields so as to make people increasingly need technology to facilitate all the work in this life. The election of the Student Council Chairperson using this election system is a process of learning democracy directly for all students. In carrying out its activities the election of the student council president at a school is still often found using simple information delivery media in the form of only sheets of paper to convey a vision and mission, then even when the election is still using paper sheets to select candidates so that they are still not maximized. By utilizing computerized technology by using a web-based OSIS (e-voting) leader election application can make the selection of OSIS chair election activities easier in conveying information, faster in performing vote counts, and making more efficient on paper so that the results obtained can be effective and efficient . So it is necessary to conduct research to analyze, design and implement an E-Voting System for Student Council Chair with Web-based Election in Schools.

Abstract

Attendance data is included in the formative value, at this time PT.Indosaluyu Primajaya still uses a manual system, this system has the potential to cause problems in the form of data present on paper that does not match the number of employees present in the office. The solution is to design absences using QR Code and geofence on Android as security when taking absences, in order to prevent students outside the PT.Indosaluyu Primajaya area from filling in absences. From the results of this system design, it produces a paperless system and prevents manipulation of absent data.
