Abstract

The flight security and reliability the most important issues for the commercialflight company at themoment, to give the scure and competitive services. One of the important factor in this relation is themaintenance system of the part of the airplane it self. The research was conducted that aim the failurecharacteristic ofthe airplane part use the stayiscal Weibull distribution method The location or research isat Garuda Maintenance Facility, in Soekarno-Hatta airport, and take thefailure data ofheat exchanger as asample. The research concluded that, thefailure characteristic Pless than on eis indicated that thefailure isin the beginning ofpart usage. Therefore, continuing research should be conducted tofind the specificfactorthat influenceresult

Abstract

Saat ini perusahaan Telekomunikasi melakukan transformasi model bisnis melalui Manage service, untuk mengurangi beban biaya perusahaan. Perusahaan telekomunikasi sangat melekat dengan teknologi mutakhir dan padat modal, maka transformasi perlu dilakukan dengan pendekatan khusus sehingga dapat mempertahankan daya saing, bukan sekedar outsourcing karyawan umumnya. Hal ini kemudian mengubah paradigma outsourcing dalam industri telekomunikasi global dalam sebuah istilah Manage service.Perusahaan menyadari bahwa Manage service ternyatarumit didefinisikan apalagi dieksekusi, sehingga perlu dilakukan pengukuran tingkat kematangan dalam skala aktivitas atau proses bisnis yang akan dialihdayakan. Penelitian dilakukan untuk mengukur tingkat kematangan proses bisnis dalam Manage services, menghasilkan penataan ulang model bisnis perusahaan.Peneliti menggunakan framework eTOM dan IT-IL dalam mengukur unit bisnis "Customer Relationship Management - Customer Care" yang akan menerapkan Manage service. Hasil studi adalah berbagai aspek identifikasi terkait dengan layanan potensial outsourcing yang dikelola, saran restrukturisasi tata kelola sesuai dengan referensi tingkat kematangan, dan memberikan rekomendasi kebijakan yang tepat.

Abstract

In the midst of the issue of limited natural resources, technological developments and industry, fishermen, especially Krueng Aceh fishermen who use the light fishing system at night to catch fish, have problems because they still use fuel to operate a portable electric generator.Researchers will conduct applied research on alternative electric generators using batteries and utilizing the Flywheel effect, with 48 Volt battery power, against a 36 volt BLDC electric motor and a capacity of 350 watts. This energy source from the battery will be used as the main source.The purpose of this research is to test the performance of an alternative electric generator powered by battery and flywheel without load and using a load (100,200 and 300 Watt AC electric lamps). The method that will be used is a direct test experiment with a light fishing system on a 3 GT fishing vessel Krueng Aceh.The results obtained from testing the performance of a generator without a load using a 37 kg flywheel, 42 cm diameter, 5 cm thick, and a battery voltage of 48 volts with a capacity of 20 Ah, capable of producing an AC output current with a voltage of 220 volts, 1500 RPM rotation, a frequency of 50 Hz. no burden. For testing with a light bulb load of 100 watts, the alternator RPM is 1500, the voltage is 210 Volts. As for the 200 watt load, the 1400 RPM voltage drops to 200 and the 300 Watt load RPM alternator 1200, the voltage is 110 volts.Keywords: Alternator, Battery, Battery Case, Electric Motor Flywheel.
