<![CDATA[Meningkatnya penggunaan beban non-linier dalam instalasi kelistrikan mengakibatkan masalah distorsi harmonik dalam sistem kelistrikan industrial dan komersial.Beban non-linier yang banyak digunakan dalam operasi minyak dan gas bumi adalah variable speed drive (VSD) dan uninterruptible power supply (UPS). PT Medco E&P Indonesia memberdayakan Electrical Submersible Pump (ESP) sebagai metode produksi minyak bumi yang diterapkan di lapangan produksi Kaji Semoga. Instalasi ESP dilengkapi dengan VSD sebagai pendukung asut dan pengendali kecepatan motor penggerak ESP demi mencapai besaran produksi minyak bumi. Operasi VSD membangkitkan gangguan harmonik yang dapat mengganggu sistem daya listrik seperti panas berlebih dari peralatan listrik, kegagalan prematur pada peralatan berputar dan pembatas arus yang gagal kerja. Pada umumnya untuk mengendalikan masalah ini, harmonic filter dipasang untuk mengkompensasi distorsi harmonik. Instalasi harmonic filter berkontribusi pada biaya pemeliharan kehandalan sistem daya listrik di lapangan produksi Kaji Semoga. Makalah ini menjabarkan metode-metode alternatif untuk mengendalikan distorsi harmonik dalam sistem distribusi daya lsitrik termasuk pemasangan harmonic filter. Metode untuk mengendalikan distorsi harmoniktersebut termasuk penggunaan trafo phase-shifting. Metode lain untuk menanggulangi distorsi harmonik adalah merancang ukuran konduktor selain sebagai proteksi arus beban-lebih juga bisa menerima pengaruhharmonic pada arus beban. Metode-metode alternatif ini bisa mengurangi biaya dari usaha menghilangkan distorsi harmonik secara signifikan.]]>

<![CDATA[The alarm device is very important in a vehicle, especially on four-wheeled vehicles. Alarm device installed to avoid in case of danger of theft or destruction of the car. So designed car alarm system that can send short message to car owner who use AT89S52 microcontroller. The hardware arrangement of the car alarm system uses the SMS-based AT89S52 microcontroller in this design, consisting of four main parts of the circuit, the minimum system circuit of microcontroller, power supply, serial communication, Input / Output. In SMS text sent from Wavecom M1306B modem and received by mobile (mobile phone) to SMS center or SMS Center flows in form of PDU (Protocol Data Unit). In the sms format is divided into several segments of data that each segment has a specific purpose. The segments are: SMS center number, destination number, bytes for the purpose of setting this SMS and most important is the SMS content that has been changed in the form of a PDU. To be able to send or upload SMS data to the modem and ordered the modem to send SMS data it required AT Command instructions.]]>

<![CDATA[The purpose of Grounding system design is to ensure safety for personal and equipment, andto improve fault detection of protection system.All electrical equipment should be connected to the grounding system. A system ground refers tothe point in an electrical circuit that is connected to earth. This connection point is typically at theelectrical neutral.Grounding of electrical items must be performed inside the enclosure i.e. insulated copperconductor is going to be used for earthed loop.Grounding bar of equipment, cubicle, switchboard, dedicated inside terminal boxes, lightingfittings.Lightning protection, electrical and instrument equipment should be connected to the groundingsystem separately. The objectives of lightning protection are to avoid catastrophic equipment damage and to preventpersonal injury. The energy of a lightning stroke can readily ignite flammable vapors or damageequipment.Methode of calculation used of the groundingsystem design of lightning protection is multiple vertical electrodes system.]]>

<![CDATA[Thermoelectrically technology is a technology of solid material that can be used as an alternative cooling technology besides cooling system that uses vapor compression that still uses freon. This study aims to determine the feasibility of using thermoelectrically cooling implementation in the indoor BTS (Base Transceiver Station). The use of this thermoelectrically Cooling is to maintain the ideal temperature of the battery by 25 degrees Celsius (250C) which is an ideal temperature. Research is done by testing thermoelectrically by mounting the cooling thermoelectrically in the existing battery cabinets installed in active condition. Ambient temperature measurement is done by using a measuring instrument that has been calibrated.]]>

<![CDATA[Temporary disturbance in medium-voltage air ducts is a disturbance mainly caused by lightning. This disorder is divided into two kinds according to the occurrence of lightning strikes, namely direct strike and indirect strike (induction). This disorder is very difficult to predict, therefore it needs good protection. To protect the equipment from a lightning strike then mounted arresters and arcing horn mounted on a 20kV SUTM network simultaneously. The combination of arresters and arcing horns in medium voltage networks can improve the reliability of the disturbances caused by tighter lightning. Lightning strikes an isolated conductor causing a flashover and causing a disruption to the network, and can damage the conductor, in which case the arrester and arcing horn secure the conductor so as not to break due to the spark jump followed by the current follow-up, in this paper discussed how Arresters and arcing horns installed simultaneously at medium voltage.]]>

<![CDATA[The final landfill is a place to hoard the garbage and the bin gets the last treatment. The final disposal site may be either deep or field-shaped. In recent years, dumped end landfills have finally been converted to a public open space. Final waste disposal site is one of the biggest sources of landfill gas emissions in Indonesia. In the anaerobic process, the organic material decomposes and the landfill gas is produced. This gas then converges and rises regardless of the atmosphere. This becomes dangerous because it can cause an explosion, but it can also cause photochemical smog.]]>

<![CDATA[Nowadays application of new and renewable energy as power plan renewable energy resources as power plant resource more and more increased. High penetration of renewable energy into the grid will influence the quality and reliability of the electricity system, due to the intermittent characteristic of renewable energy resources. The smart grid or microgrid technology has the ability to deal with this intermittent characteristic especially while these renewable energy resources integrated to grid in large scale, so its can improve the reliability and efficiency of that grid. We plan to implementation of smart microgrid system at School High Tehnik of PLN as a pilot project. Before the pilot project design, the feasibility study must be conducted. In this feasibility study, the renewable energy resources and load characteristic at the site will be measure. Then the technical aspect of this feasibility study will be analyze.This paper explained the analysis of thus feasibility study.]]>

<![CDATA[Push-On switches or toggle switches and mechanical relays are mechanical contacts made of metal which, when supplied with electric current, will result in a spike of electrical sparks, called Bouncing Effects. Bounce effects are often a problem in digital circuits, especially in digital electronics circuits, because these Bounce Effects will cause the value of data or signals coming into the circuit inaccurate or indeterminate, when the mechanical switch is pressed as input data. This will undoubtedly lead to undesirable conditions and must be overcome with an electronic circuit called De-Bounce for the data or input signal to be more certain.]]>
