Abstract

The goal was knew the problems which was quite risky as in terms of accessing the Internet. Therefore to know the quality of the Internet network Wireless LAN to do analysis of network performance that emphasizes how monitoring and assesing Wireless LAN network performance by measuring parameters of bandwidth, delay, and packet loss. In this study, the researcher used action research or action research as research method to describe, interpret and explain a situation or circumstance in the Wireless LAN network in STAIN Metro and analyzing the results of the calculation of the Wireless LAN network downtime to change or intervention with the aim to determine factor- factors that affect Reliability, Maintainability and Availability in the Wireless LAN network so it can provide a better network service. Packet loss network ranged between 32% - 34% occurs caused of a collision / impact packet data or each data on the network. It caused of the traffic network that increase at 10:13 until 11:15 by the number of students who access the Internet network. Beside the ingkcreasing of users, other factor was accessing content on the Internet network can be the affect bandwidth needs. Kinds of content are accessible users that may be the affect the amount of bandwidth. To reduce the packet loss resulting from the collision of the data packets, it is necessary to increase the amount of bandwidth for improving QoS on the network. It needs to setup a web proxy to the site - a site that popular networking sites such as Media Social or video streaming by using a particular port. This is very helpful for data traffic to the WAN or to a LAN

Abstract

Technology and Communications of Information (TIK) this is very needed in course development of study, but in its execution do not follow order a enterprise, can seen with system development of Information just for fulfilling an requirement to job unit division which result there no is relevant of Information system which have there is and to be woke up as solution requirement of every activity division. Education Of Ma'Arif Nahdlatul Ulama (NU) institute in Metro City find difficulties in the case integration of Information system that is change of management, what divided to become 5 School that is MI, SMP, SMA, SMK, and PT in Metro city. Constitutoing existing problem making model of enterprise in expectation improve, repair to arrange Informatioan technological management more better. Research of model of enterprise architecture Institute Education Of Ma'Arif NU in Metro city expected to yield scope of enterprise organizational in the form of especial activity and supporter activity, Architecture Vision define organizational profile, difinision of mission and vision, target of organization, organizational target, organizational unit, condition of architecture in this time and computer network.

Abstract

Representation is very important used in electrical engineering students in physics lectures. Representation consists of verbal, mathematics, diagrams, and graphs. This research uses case study method in electrical engineering students who are physics lectures. Data were collected using questionnaires, observations sheet, and interview guidlines. Based on the questionnaire, the results of the teaching materials used are not yet complete using multi representation, the lecture model does not use multi representation, and the problem is used more using verbal and mathematic representation. Electrical engineering courses are required by using multi representation.

Abstract

Kesehatan merupakan hal penting bagi manusia karena manusia memiliki tubuh yang rentan akan penyakit. Pada bidang teknologi kesehatan semua kebutuhan yang dipakai oleh ahli kesehatan sangat banyak. Kesehatan pada umumnya masih menggunakan diagnosa oleh seorang dokter secara langsung. Pada era teknologi ini diagnosa kesehatan bisa dilakukan melalui teknologi yang telah disisipi pengetahuan dari ahli pakar atau dokter. Teknologi dapat membantu para ahli medis dalam melakukan diagnosa penyakit pasien, sehingga layanan medis bisa lebih cepat dan konsisten Teknologi dalam bidang kesehatan juga dapat diterapakan dalam memprediksi berapa banyak jumlah gizi yang dibutuhkan oleh ibu hamil. Banyak ibu hamil yang belum mengetahui akan kebutuhan gizi. Untuk mengetahui jumlah kebutuhan gizi, ibu hamil harus memeriksakan kondisi fisik dan kehamilan pada bidan atau dokter. Untuk menangani hal tersebut peran bidan atau dokter sangat diperlukan, tetapi didalam kenyataan bidan atau dokter sering menghadapi kendala atau hambatan dalam melakukan pemeriksaan kondisi fisik dan kehamilan untuk mengetahui jumlah gizi karena jumlah ibu hamil yang harus ditangani begitu banyak. Sehubungan dengan hal diatas, diperlukan suatu sistem yang dapat memprediksi jumlah gizi pada ibu hamil. Sistem pakar (expert system) adalah sistem yang berusaha mengadopsi pengetahuan manusia ke komputer, agar komputer dapat menyelesaikan masalah seperti layaknya para pakar. Sistem pakar juga mengefisienkan waktu dan kinerja bagi bidan atau dokter maupun ibu hamil.

Abstract

Telah dilakukan sintesis material ferroelektrik Barium Strontium Titanat (Ba0,9Sr0,1TiO3) dengan variasi suhu sintering menggunakan metode co-precipitation. Sintesis ini bertujuan untuk mengetahui pengaruh variasi suhu sintering terhadap struktur kristal, ukuran kristal, parameter kisi dan konstanta dielektrik pada sampel Ba0,9Sr0,1TiO3. Sampel yang diperoleh berupa serbuk yang dicetak menjadi bulk, kemudian di-sintering pada suhu 700oC dan 800oC ditahan selama 4 jam. Sampel Ba0,9Sr0,1TiO3 dikarakterisasi menggunakan XRD untuk mengetahui ukuran kristal dan RCL meter untuk mengetahui konstanta dielektrik. Berdasarkan data XRD, ukuran kristal semakin besar dengan bertambah tingginya suhu sintering. Ukuran kristal pada suhu 700oC adalah 24,14 nm dan pada suhu 800oC adalah 27,65 nm. Pengujian menggunakan RCL meter diperoleh konstanta dielektrik pada suhu 700oC sebesar 194,98 dan pada suhu 800oC sebesar 199,11.
