Malware attacks on the Internet have increasedsubstantially in recent years for which botnets are a root cause. A "botnet" is a network of compromised computers controlled by an attacker known as the "botmaster". To be able to effectively detect and…
Monitoring the output parameters of a solar module is required for assessing its performance under real operating conditions. This paper presents a new technique for monitoring the output parameters i.e. current and voltage of solar module directly…
Design layout 1-stage pipeline is part of the 8-stage pipeline 80 Msps ADC. Layout 1-stage pipeline consists of 3 units : op-amp, switch capacitor, precision comparator with latch. Pipeline ADC works gradually and requires synchronization of digital…
Banyak faktor yang dapat mempengaruhi kualitasdan kestabilan koneksi HSDPA. Dalam penelitian inidifokuskan pada pengukuran dan analisa kinerja jaringanHSDPA dengan parameter-parameter user data throughput,round trip time, dan packet loss. Dari hasil…
Abstrak—Direct Digital Synthesizer (DDS) merupakan metode pembangkit gelombang analog secara digital dengan cara membangkitkan sinyal digital yang berubah-ubah terhadap waktu kemudian diubah kedalam bentuk analog menggunakan…
Polymer insulators have become an alternative to change the ceramic insulator because it has a better dielectric properties, mass density is lighter and can be made at room temperature vulcanized so it is economically more advantageous. But, the…
A type of solar battery charger is introduced in this paper. This equipment functions as a medium size rechargeable battery that is needed to move culinary merchants and coastal fishermen living in area which is not supplied by electrical networks.…
Hybrid PV-Grid menggabungkan dua sumber energi listrik yaitu grid (PLN) dan PV (Photovoltaics). Tegangan dari sumber PV sebesar 48 volt dc dinaikan dan diubah ke tegangan ac 280 volt dengan menggunakan konverter. Sedangkan sumber dari grid dijadikan…
In the industry era, especially the oil processing industry, the heat exchanger is needed to regulate temperature and produce oil products such as petroleum, kerosene and diesel fuel. In the operation, the heat exchanger requires maintenance,…
Fermentation optimizer aids have been common around us in both laboratories and home industries. However, these aids only served as incubator and sometimes cannot optimize the fermentation process due to the increasing humidity in a closed box.…
