Abstract

Utilization Learning Management System in college used to improve learning services to students. The purpose of this study to examine the variables and indicators that affect the success of LMS systems with exelsa USD as a case study. The model used in this study was adapted from the model of success of DeLone-McLean. Questionnaires were distributed to the students and the samples taken by stratified random sampling, and obtained 448 respondents. Data were processed using Structured Equation Modeling, and conducted tests on the measurement model and the model structure. The variables used in this study is the quality system, the quality of information, emakaian, user satisfaction, individual impact and organizational impact. From the results of this study showed that the quality system and quality of existing information on LMS exelsa very influential on the use and satisfaction of users, the use of the system is not felt by the wearer have a positive impact on the individual, but the satisfaction in use that have a positive impact on individuals, as well as the individual impact seen also influence / impact positively on the organization (in this case the university).

Abstract

Teknologi multimedia merupakan Salah satu teknologi yang ditawarkan dalam media pembelajaran alternatif untuk dimanfaatkan dalam dunia pendidikan saat ini. Hardcopy yang digunakan dalam Proses Belajar Mengajar terkadang menyulitkan pelaku pendidikan dalam hal mengakses dan menerima informasi secara cepat dan realtime, sehingga memunculkan ide untuk mengembangkan materi pelajaran dalam bentuk multimedia, yang akan memudahkan pendidik dan peserta didik dalam menjalankan aktivitas dalam PMB. Kejenuhan belajar akan muncul Apabila pendidik selalu menggunakan metode yang konvensional secara terus menerus dan tanpa ada variasi, karena tidak ada warna baru dalam PBM. Implikasi dari metode belajar secara konvensional yang digunakan oleh tenaga pendidik, menunjukkan bahwa 20% atau lebih peserta didik kurang antusias dan berminat mempelajari materi, 35% atau lebih peserta didik kurang mempunyai inisiatif untuk mencari atau memperdalam wawasan melalui referensi lain selain yang diberikan oleh tenaga pendidik. Permasalahan lain adalah, ketersediaan sumber belajar di perpustakaan sangat minim, sehingga materi yang didapat pun kurang up to date. Hal ini semakin memperkuat permasalahan kurang berminat dan rendahnya inisiatif peserta didik dalam proses belajar mengajar.Pada penelitian ini,dikembangkan multimedia dan pemodelan multimedia yang dapat meningkatkan Self Motivated Learning dan Self Regulated Learning dengan menggunakan metode penelitian pengembangan research and development, dan analisi akhir dilakukan pengujian dengan bantuan SPSS.Model digitalisasi media pembelajaran ini mampu membuat peserta didik menjadi tertarik untuk belajar secara aktif dan mandiri.

Abstract

A reliable pipeline design requires hydrodynamic analysis. The analysis enables flow rate and pressure gradient investigations in obtaining an optimum configuration. In the other hand, a numerical approach occurs as a complex schematic is proposed. Solving this requirement, an iterative method is posible to be endorsed. This study aims to investigate single-phase gas pipeline hydrodynamic analysis. A model utilized a two-phase pressure gradient correlation, namely Beggs-Brill correlation, to converse single-phase gas pressure gradients into mass flow rates. Furthermore, the numerical method, called Newton-Raphson, is assesed on solving those iterative calculations. The results show that the model is able to solve a complex schematic. The mass flow rates obtain in the deviation up to 0.4 %, whereas the pressure gradients deviation is achieved on a higher value.

Abstract

One application of direct evaporation cooling system was a natural refrigerator. The advantages of this natural refrigerator was operating without using electrical energy or mechanical energy and environmentally friendly. This study aims to gain a performance analysis of natural refrigerator as a store of vegetables and fruits which uses water as the cooling medium. Material of natural refrigerator consists of teak wood and gunny. Experiments were conducted during seven days in the open space which exposure to solar radiation. The measurement of weather parameter was done by using HOBO devices and to record temperature changes of vegetables and fruits in the natural refrigerator was used acquisition data. The results showed that the efficiency of natural refrigerator maximum that can be obtained was 14.7% with an average air temperature of 25,55oC, air humidity average of 91.34% and an average solar radiation of 108.45 W/m2. The experimental data showed that the freshness of vegetables and fruits heavily influenced by weather conditions.
