This renovation also replace or convert lamps that previously used TL 2 x 36 Watt lamps to use 40 Watt LED flat lights. In this case the aim to know this comparison is by calculating theoretically strong illumination, the power generated as well as the cost incurred. From the comparison results obtained the comparison terotirs how the better and see the two lights are whether the standard qualified lighting in the arena shooting space That LED lights have a strong light almost the same as the TL lamps but in terms of electric power used LED lights generate more electrical power small with a smaller electric power is obtained electricity tariffs are also cheap, so LEDs can be very energy-efficient lamps and save money. Dengan adanya momentum pergelaran kompetisi olahraga tingkat Asia yaitu Asian Games 2018 yang akan diadakan di Jakarta dan Palembang, Jakabaring Shooting Range Palembang melakukan renovasi pada gedungnya untuk menunjang suksesnya Asian Games 2018 pada cabang olahraga menembak. Renovasi ini juga menganti atau mengkonversikan lampu yang sebelumnya menggunakan lampu TL 2 x 36 Watt menjadi menggunakan lampu flat LED 40 Watt. Dalam hal ini bertujuan untuk mengetahui perbandingan ini adalah dengan menghitung secara teoritis kuat penerangan, daya yang dihasilkan serta biaya yang dikeluarkan. Dari hasil perbandingan didapatkan perbandingan secara terotirs bagaimana yang lebih baiknya dan melihat kedua lampu tersebut apakah memenuhi syarat standar penerangan pada ruang arena menembak Bahwa lampu LED memiliki kuat penerangan hampir sama dengan lampu TL tetapi dari segi daya listrik yang digunakan lampu LED menghasilkan daya listrik yang lebih kecil dengan daya listrik yang lebih kecil ini didapat tarif listrik yang murah pula, dengan begitu LED sangat bisa menjadi lampu yang hemat energi serta hemat pengeluaran uang.","PeriodicalId":404492,"journal":{"name":"Jurnal Ampere","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121429899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This cable bending will affect cable characteristics, one of which changes the cable resistance value. This study will discuss the effect of cable bending on the value of resistance. Data is taken by experimenting with a voltage and current flowing on a cable that is not bent and with a cable that is bent once, twice, thrice, four times and five times bending. From the results of the test, the calculation is obtained and the following results are obtained: for cables that are not bent, the resistance value is 900 Ohm / km. The cable is bent once, the resistance value is 600 Ohm / km. Whereas for cables that are bent twice at 700 Ohm / km, they are bent three times to 550 Ohm / km, four times 700 Ohm / km and five times 560 Ohm / km. The up and down measurement results occur because the bending direction is not always in the same direction.
