Abstract

Presidential Instruction recently about saving and energt efficiency, it is necessary that efforts should be made to support the program. In energy savings in the household sector can be done in various wavs from the smallest thing turning off lights that are not necessary to the utilization of waste heatfrom air conditioning to hot water purposes. Alternative technologies, the heat energy generated by the air conditioning unit is the potential energy that can be utilized to get hot water for free. Given theclimate in Indonesia is quite hot, many hospitals, hotels, residential upper middle or apartment is equipped with air-conditioning and heat generated in the cooling system is disposed into the environment. Infact. the heat energy can be used for heating water can be usedf or water bath or otherpurposes. It is necessary to develop a means of combined cooling and heating water. These devices are expected simultaneously to increase comfort and save energy.Keywords: Conservation of energy in refrigeration I pk

Abstract

Kondisi topografi Kampus Universitas Muhammadiyah yang tersebar di 3 lokasi yang berjauhan dibutuhkan perancangan jaringan komunikasi data yang handal. Kontur 3 kampus yang terpisah lembah dan naik turun membuat perancangan implementasi jaringan wirelless LAN menjadi pilihan. Teknologi wireless memberikan kemudahan untuk mengkoneksikan simpul-simpul komputer tanpa perlu menarik kabel, perangkatnya mempunyai fleksibelitas yang tinggi. Teknologi wireless menggunakan teknologi gelombang radio yang menggabungkan sinyal frekwensi rendah dan gelombang pembawa yang frekwensinya tinggi ke dalam modulator yang kemudian dikonversikan ke gelombang elektromagnetik dan dipancarkan ke udara. Disisi lain untuk menerapkan teknologi ini membutuhkan kaidah perencanaan dalam perencanaannya untuk menghasilkan komunikasi yang handal.Kata Kunci : Wireless LAN, WAN, dan Komunikasi data

Abstract

Use of utility electric motor in an industry become is a basic requirement, electric motor serves as a means of supporting drivers / mechanics of a tool such as pumps, chillers, conveyors etc. The electric motor takes energy consumption in the world's greatest industrial and motors is expected to use about 70% of the total electrical load in the industry. This research aims to analyze unbalanced load on electric motor and how to solve that problems. Unnecessary consumption of energy from the electric motor is usually caused inefficiencies and unbalanced load burden. For that we need ways to makeconservation / energy saving programs.Keywords: electric motor, inefficiency load, unbalanced load, energy conservation

Abstract

Platform Web 2.0 utilities are websites that are colaburative, interactive, allowing users not only to read information but also to post information and interact with others. These tools offer new opportunities for designing instruction for heightened student engagement, particularly inlearning. This paper is a very practical introduction to using common Web 2.0 tools including wikis, blogs, social media, and social bookmarking sites etc. Sample assignments developed and used by the author or described in the literature are described. These assignments are adaptable for use in a variety of disciplines. Wikis are very useful for group work. Blogs can be used effectively for journals and independent studies. Social bookmarking can enhance organization and sharing of professional web resources. Specific tips for setting up and working with the sites are given as well as recommended resources including handouts and videos that introduce the sites.

Abstract

A bolt of lightning strikes the induction is on the ground near a transmission line resulting in a phenomenon that caused of trensient electromagnetic fields from the lightning channel. This phenomenon is happening at lightning conductor wire. This event raised over voltage and resulting wave propagating on both sides of the wire in the strike lasts. In calculating the induction stroke used Shielded Factor (FP) is defined as the quotient ofthe induced voltage and induced voltage ground wire without a ground wire. If there is no ground wire, the neutral wire effect on induced voltage on the wire the same phase as the influence of the ground wire to the voltage induced in the phase wire. Since the neutral high wire above the ground is lower than the high-wire phase, greater than shielded factor of the channel with the ground wire. There are times when the neutral wire was installed over the wire so that the phase factor will be smaller shielded. Construction is crucial lightning disturbances. From this analysis concluded that the results obtained from data disruption due to lightning feeder PMT 4 GI BSB obtained 3 times a distraction while the calculation results showed interference by 4 times with 24.4 km length of the network there is no significant difference. Any differences due to changes in network construction are not communicated as elevation neutral wire that will affect shielded factor.

Abstract

Power Plant units are responsible for providing power generation in the power system so that the load can be served.Poer Plant units may trouble each time. The disorder resulting plants cannot operate. If this interference occurs at the same time on several large generating units, it is possible that the power available in the system is reduced such that the system is not sufficient to serve the load. Reliability cf the electrical system must be maintained and enhanced, so that the load needs to be served. Thus it is necessary to investigate whether or not the reliability of the system every year. Reliability of the electrical system can be determined by calculating the value of (loss of load probability) LOLP with units of days / year. The smaller the value, the better the level of LOLPkendalan an electrical system. In 2009 the electrical system of Central Java and Yogyakarta not meet the standards, ie the value of LOLP 4.088 days / year. For the years 2010 and 2011 has increased reliability and meet the standards, with the value of 0.043 days in 2010 and 0.017 in 2011 days.Keywords: LOLP, reliability of Electric Power Systems
