Penggunaan sistem informasi penunjang seperti e-filling, e-ktp, e-procurement dan sebagainya yang sudah mulai diperkenalkan bagi masyarakat luas maupun individu-individu tertentu oleh pemerintah sudah cukup baik, namun sangat jauh berbeda bila kita cermati bagaimana upaya dan usaha pemerintah mendukung demokrasi dalam proses pemilihan umum dengan menggunakan e-voting, padahal saat ini memiliki banyak permasalahan yang memicu konflik-konflik horizontal ditengah masyarakat akibat proses pemilihan umum. Penelitian ini memiliki tujuan (1) memberikan bukti empiris tentang pengaruh e-voting yang diterapkan pada tingkat partisipasi yang didasarkan pada model teknologi ditawarkan, (2) menentukan pengaruh langsung variabel prediktor termasuk performance expectancy, effort expectancy, facilitating condition, mobility, security & privacy dan experience untuk tingkat partisipasi masyarakat. Faktor yang diteliti dalam penelitian ini menggunakan model UTAUT. Hasil penelitian menjelaskan bahwa penerimaan teknologi REVS dipengaruhi oleh variabel performance expectancy, dimana pemilih berharap agar rekapitulasi hasil suara bisa tepat dan akurat. Selanjutnya adalah variabel mobility dimana pemilih percaya mereka dapat melakukan pemilihan dimana pun mereka berada, tidak dihalangi oleh aturan yang mengharuskan mereka untuk menghadiri ditempat tertentu, sedangkan untuk security & privacy pemilih menginginkan sistem pemilu yang aman dari ancaman baik internal dan eksternal dan tetap menjaga nilai-nilai privasi.

Existence of constraints increases difficulty in choosing the right goods for a seller. Indeed, the seller wants to optimize the profit gained. Due to limitation of capital and maximum capacity, the seller needs a certain strategy to do the selection. Moreover the fact that each goods has its own probability to sell makes the problem becomes more complex. In this paper, the problem is solved using genetic algorithm. The result of simulation is in a good agreement with analytical solution. The simulation of N-goods selection is also given in the paper.

The goal of this work is to design and build a vibration test bench to simulate unbalance in rotating machine. The vibration test bench made of a 25 mm diameter steel shaft and length of 410 mm supported by two ball bearings. Two steel discs to variate unbalance load installed in the shaft powered by 0.5 Hp electric motor with maximum rotation of 1400 RPM. Inverter used to control rotation from electric motor. Vibration testing conducted at two condition; (1) without load and rotation variation, (2) unbalance load with variation of unbalance mass. Pick up point of vibration measurement at bearing house in radial and axial direction. The vibration parameter measured are amplitude and spectrum (wave form). Amplitude measurement using hand held vibrometer, while spectrum using accelerometer conected to a Data Acquisition. After testing the condition using unbalance load, we conclude that the vibration test bench match unbalance condition as described in theory which is high amplitude at machine frequency, and it’s value proportional to unbalance mass. We find that the highest amplitude is at horizontal direction where machine stiffnes is smallest. Vibration testing with no load condition show that there is harmonic in vibration spectrum indicating rotating looseness, probably caused by bearing wear.
