Abstract

Pada tulisan ini dibahas perancangan dan pembuatan dari konverter DC-DC (DC Chopper). Konverter DC–DC sendiri merupakan suatu alat yang dapat mengubah satu bentuk daya listrik searah ke bentuk daya listrik searah lainya, baik itu menurunkan atau menaikkan. Pada umumnya, rangkaian konverter terbagi atas 4 jenis yaitu buck, boost, buck-boost dan cuk. Pada pembuatan tugas akhir ini akan diracang sebuah rangkaian konverter DC-DC tipe Buck. Konverter Buck merupakan sebuah konverter yang digunakan untuk menghasilkan tegangan keluaran searah (DC) yang lebih rendah daripada tegangan masukannya. Penurunan tegangan keluaran dari konverter dilakukan dengan mengatur lebar pulsa (PWM). Pengubahan besar kecilnya PWM dilakukan dengan meggunakan komponen switching berupa MOSFET, serta penggunaan gate driver yang berfungsi sebagai penguatan sinyal dan pengaman antara rangkaian kontrol dan rangkaian utamanya. Tegangan masukan dari konverter dirancang sebesar 24 VDC, dengan tegangan keluaran 24VDC-12VDC. Keluaran dari konverter dapat dilihat melalui PC menggunakan software Visual Studio 2012. Penambahan interfacing menggunakan Visual Studio 2012 dapat memudahkan para pengguna untuk melihat keluaran dari konverter.

Abstract

Pada saat ini pengoptimalan cahaya matahari dengan menggunakan panel surya masih kurang optimal ini dikarenakan kebanyakan panel surya masih diletakkan hanya menghadap satu arah ini mengakibatkan proses penyerapan cahaya matahari oleh panel surya hanya akan terjadi apabila matahari tepat berada di atas panel surya. Perlu dibuat suatu sistem yang dapat membuat solar cell selalu mengikuti arah pergerakan matahari dan juga dapat mamantau nalai yang dihasilkan oleh solar cell. pelacak cahaya matahari merupakan alat yang digunakan untuk mengikuti arah gerak matahari. Cara alat ini bekerja yaitu dengan mengindera perubahan arah cahaya yang dipancarkan oleh matahari. Dalam hal ini hasil dari pelacakan cahaya matahari di pantau melalui web thinger, hal ini memudahkan kita dalam melihat dan menganalisis hasil yang didapatkan dari solar cell. Dari hasil pengujian didapatkan penggunaan sistem monitoring hasil pelacakan cahaya matahari sangat efisien dan memudahkan kita dalam melihat data-data yang dibutuhkan.

Abstract

ABSTRACTThe existence of information and communication technology (ICT) in an organization is expected to increase the efficiency and effectiveness of the organization. This condition is sometimes far from what is expected and instead slows organizational activities such as the ability to use computer-based information systems that are still low, and user experience is still small so that it affects the acceptance of an information system. Job Analysis and Workload Analysis Information System (SINJAB) is designed to provide the results of job analysis and workload analysis from a Central / Regional agency for the implementation of institutional, staffing, management and supervision arrangements to the competency-based apparatus and performance. This article discusses the process of measuring the usefulness of the acceptance of the SINJAB. The method used is the Technology Acceptance Model (TAM). The parameters used to measure variable factors such as experience, self-confidence, perceived usefulness, and perceived ease of use on the acceptance of the SINJAB. The object of the study was conducted at the Government of the City of Payakumbuh, West Sumatra. The findings state all the factors of experience, self-confidence, perceived usefulness, and perceived ease affect the SINJAB.Keywords:Keywords: ICT, SINJAB ,technology acceptance modelABSTRAKKeberadaan teknologi informasi dan komunikasi (TIK) dalam suatu organisasi diharapkan dapat meningkat efisien dan efektifitas organisasi.

Abstract

In this paper, the harmonic distortion for Self-Excited Induction Generator (SEIG) and an isolated synchronous generator (ISG) under non-linear load during steady state conditions are analyzed. The voltage and current harmonics distortion for both generators are calculated using the transfer function method in frequency domain for SEIG and phasor diagram method for ISG. This analysis is done independently one by one component for all harmonic components appear. The analysis results for both generators are verified to the laboratory test results. For loading with the same non-linear load to both generators, the harmonics distortion on the stator windings of SEIG was smaller than compare ISG. In addition, the harmonic distortion effects on other loads connected to PCC point of SEIG was lower than the other loads connected to ISG.
