Abstract

One of the main components of the fountain solution used for the offset printing technique is isoprophil alcohol (IPA), which is related to its function as a surface tension reducing agent, cooling agent for printing plates and at the same time having anti-bioorganic function. However, complaints have also been made about the weaknesses in the use of IPA related to odor, toxicity and too high evaporation rate during its use. Therefore, in this article, IPA is compared to the "alcohol-free" type when used in the field as a wetting solution mixture using a KBK offset printing machine to produce magazines using of AP 115 paper. The difference in the use of the two surfaces the tension reducing agents are identified by the waste parameters that are used, generated during consistent printing under controlled process conditions. The results obtained indicate that the use of IPA is always higher, but the use of `` non alcoholic '' tends to be more stable in controling the process.Keywords—Isoprophil Alcohol (IPA), alcohol-free fontain solution, offset printing

Abstract

 This study aims to examine the effect of physical evidence, reliability, responsiveness, assurance and empathy on consumer satisfaction (Studies in the Library of the Faculty of Economics and Business, University of Malikussaleh). The data used are primary data by using accidental sampling method. The sample used was 142 visitors to the Library of the Faculty of Economics and Business, University of Malikussaleh. The results of the study partially show that the variables of Physical Evidence, Responsiveness, Assurance and Empathy have a significant effect on the variable of Customer Satisfaction (Studies in the Library of the Faculty of Economics and Business, University of Malikussaleh). While the reliability variable does not have a significant affect on to consumer Satisfaction variable (Study at the Library of the Faculty of Economics and Business, University of Malikussaleh). Simultaneously the results of this study indicate that physical evidence, reliability, responsiveness, assurance and empathy have a significant effect on the dependent variable of consumer satisfaction (Studies in the Library of the Faculty of Economics and Business, University of Malikussaleh). Keywords: Physical Evidence, Reliability, Responsiveness, Guarantee of Empathy and Customer   Satisfaction

Abstract

Abstract—Penggunaan ilmu pengetahuan dan teknologi semakin meningkat terutama dibidang elektronika. Salah satunya dengan berbagai macam penggunaan sensor accelerometer. Sensor accelerometer adalah sensor untuk mengukur kecepatan getaran. Getaran adalah gejala mekanika, dinamik yang mencakup periode gerak osilator di sekitar posisi referensi atau berupa gerakan bolak-balik yang digambarkan sebagai amplitudo atau simpangan terjauh dari titik setimbang. Untuk mendeteksi getaran dikembangkan berbagai alat berupa sensor getaran. Terdapat banyak metode atau teknik yang dipakai untuk mendeteksi getaran, Alat ukur getaran saat ini sangat dibutuhkan, seperti deteksi getaran mesin,dan benda-bedan yang menimbulkan getaran. Membuat alat ukur getaran menggunakan sensor acceleromter yang portebel dengan tegangan keluaran X,Y adalah 1,61 Volt dan Z 2,45 Volt Hasil getaran akan ditampilkan pada LCD dan grafik akan ditampilkan pada tampilan PC, hasil dari pengukuran dapat di simpan di data base (ms.excel),Dengan Frekwensi 67 Hz.Kata kunci: Getaran, Alat ukur, AccelerometerAbstract— The use of science and technology is increasing, especially in the field of electronics. One of them is by using various types of accelerometer sensors. The accelerometer sensor is a sensor for measuring the speed of vibration. Vibration is a mechanical, dynamic phenomenon that includes a period of motion of the oscillator around a reference position or in the form of back and forth motion which is described as the amplitude or the furthest deviation from the equilibrium point. To detect vibration, various tools have been developed in the form of a vibration sensor. There are many methods or techniques used to detect vibrations. Vibration measuring instruments are currently needed, such as the detection of engine vibrations, and objects that cause vibrations. Make a vibration measuring instrument using a portable accelerometer sensor with an output voltage of X, Y is 1.61 Volts and Z 2.45 Volts. The vibration results will be displayed on the LCD and the graph will be displayed on the PC display, the results of the measurements can be stored in the data base ( ms.excel), with a frequency of 67 Hz.Keywords: Vibration, measuring instrument, Accelerometer

Abstract

The proper ablution place becomes one of mosque facilities to be concerned by the community and completed by the water used for ablution activity. The water used in Muhajirin Mosque is sourced from Tirta Daroy Regional Drinking Water Company (PDAM), but the supply is less smooth impacting the water used for ablution activity during the praying times is insufficient. It is required to build water storage with the dimension 3 m x 1.5 m x 1.2 m. The water storage is utilized to fill the water when the PDAM water supply is smooth to solve the water deficit for ablution. The implementation of this community dedication activity consists of survey and observation, drawing designing, discussion, building construction and hand over activity. The output of this activity is providing supporting building used for ablution activity to the community surrounding Muhajirin Mosque in Punge Blang Cut Village, Jaya Baru Sub District, Banda Aceh City. This building is useful for the ablution water need in the praying times and other significant benefits for community. The follow up of this activity is expected to be built a water reservoir as the water reserve to save the electricity and to ensure that the water will be supply if the electricity is off.Keyword: Build water storage, ablution place, mosque

Abstract

Sistem pendukung keputusan merupakan sistem informasi interaktif yang menyediakan informasi, pemodelan dan pemanipulasian data. Sistem ini digunakan untuk membantu pengabilan keputusan dalam situasi yang semi terstruktur dan situasi tidak terstruktur. Sistem pendukung keputusan dibangun untuk mendukung solusi atas suatu masalah atau untuk mengevaluasi suatu peluang. Begitu pun untuk menentukan bidang keahlian pada SMK Swasta Mulia Pratama. Untuk menentukan bidang keahlian setiap siswa, maka dibutuhkan suatu metode promethee agar dapat memudahkan sekolah dalam menentukan bidang keahlian siswa/I tanpa harus mewawancarai secara langsung. Metode promethee ini sering disebut dengan metode penjumlahan terbobot. Konsep dasar metode promethe adalah mencari penjumlahan terbobot dari rating kinerja pada setiap alternatif pada semua atribut.
