Abstract

ABSTRAKApartemen X merupakan sebuah bangunan yang didalamnya terdiri dari area parkir atau basement,ruang ME (ruang kontrol panel), tangga kebakaran atau evakuasi, utilitas, fasilitas publik (lobby lift), koridorapartemen, ruang ganti, unit hunian apartemen. Sumber penerangan harus memenuhi standar dan disesuaikandengan indera penglihatan manusia, demi memberikan kenyamanan dalam berbagai aktifitas.Untuk itu dalammenghitung jumlah kebutuhan lampu yang terpakai dari lampu TL, CFL dan LED, dihitung berdasarkan besarnilai lux pada suatu ruangan, luas ruangan, nilai lumen, nilai effisiensi penerangan dan faktor depresiasi ataunilai pengurangan pengotoran lampu, nilai cos phi atau cosinus beban lampu.Dari hasil perhitungan untuk pemakaian energy listrik pada sebuah apartemen, diperlukan energylistrik sebesar 508,47MWh untuk lampu LED, sedang untuk lampu TL elektronik 682,9 MWh per tahun. Dengandemikian penggunaan lampu LED lebih hemat 25,54 % dibandingkan lampu TL elektronik

Abstract

Age-old mill still experiencing demands to improve the quality and oroduction capacity.Repair, renovation, addition of electrical equipment and production machines as supportingproduction should be done. For electrical equipment and machinery are aged beyond safe time limit.One of them : ACB-type circuit breaker point A, imposition of electrical equipment that exceed the timelimit on the plant safe will result in severe, be a disturbance explosion-fire resulting in total failureproduction. Being burdened Cane Cutter machines I which require a large torque because there is avery extreme narrow gap. Than the energy required large power, it takes great energy power,electrical system and installation of electrical equipment must consider regulatory electricity and PUIL2000 or international standards, so that the continuity of safe electric power energy. The use of electricmotor / Cane Cutter I should be considered more in the electrical system, due for chopping sugar cane,then a very large load torque too great and the gap in the extreme, can lead to Locked Rotor. Denganmethod IEC 60 909 in 2000 to calculate the locked rotor current noise ; simplification because thecalculation does not depend on the operating status of ongoing and future load flows. With a series ofanalyzes and short-circuit current using the formula of the total of 3-phase symmetrical fault currentobtained with the largest load disconnection times faster than the time settings. This fault currentDownstream ACB protected and unprotected then the Upstream ACB who do it (ACB point A), thisfault current lead to an explosion / fire in the ACB point A. ACB possible point A has exceeded the timelimit is safe and functioning of protection equipment ACB point A is Electronic or Solid state Trip Unit/ fully adjustable, the fault current exceeds safe limits (Imax overload dan fully adjustabl

Abstract

The intensity total of lightning in Indonesia area, especially in West Java and Banten is quite high, above 100 times / year / 100 km2, so it requires a protection system to prevent interference from lightning strikes, one of which is the shield system. The shield systems of substations is very closely related to the shape of the switchyard. The shield system design is done by adjusting the height of the tower and the ground wire to get the optimum altitude. The definition of an optimal state in this case is limited to the situation where there is the quality that is not beyond the point of tolerance has technical and cost efficiency. Its design is taken as a comparative study between several methods, including Elektrogeometri Theory, Fixed Angle, and Empirical curve. The calculation and analysis concluded that the theory Elektrogeometri with a distance of 28 m and a high tower of 18.994 m is the best choice in the design of system optimization, compared with other theories to meet the quality criteria for distance security shield.
