Abstract

Pengukuran intensitas radiasi pada beberapa filter rokok komersial menggunakan detektor Geiger-Muller dengan sumber radiasi Sr-90 dan Am-241 telah dilakukan. Pengukuran ini dilakukan untuk menghitung besarnya koefisien atenuasi dari filter rokok tersebut. Dalam penelitian ini, jarak dari filter rokok dengan sumber radiasi divariasikan yakni sebesar 6 cm, 7 cm dan 8 cm. Terdapat dua jenis perlakuan sampel yakni sampel filter yang mendapatkan gaya tekan sebesar 5 ton selama 10 menit dan non-tekan (kondisi normal). Hasil penelitian menunjukkan bahwa semakin jauh sumber radiasi terhadap detektor, maka semakin kecil intensitas radiasi yang diperoleh. Daya tembus radiasi dengan sumber Sr-90 lebih besar dibandingkan dengan radiasi Am-241. Oleh karena itu, unsur radioaktif Sr-90 memiliki intensitas yang lebih besar dibandingkan dengan unsur radioaktif Am-241. Study on amount of radiation intensity for some commercial cigarette filters using detector Geiger-Muller with radiation source of Sr-90 and Am-241 has been done. The purpose of the measurement is to measure a mass attenuation of the filter. In this research, the distance of the cigarette filters with the source of radiation was varied i.e 6 cm, 7 cm and 8 cm. The sample cigarette filters was treated, i.e press and non-press (normal condition). The cigarette filters are pressed with a force of 5 tons for 10 minutes using hydraulic press. It was founded that the radiation intensity will decrease with the distance. The amount of radiation intensity of Sr-90 is more higher than Am-241.

Abstract

Telah dilakukanan penelitian terhadap kecepatan angin di kawasan Blang Bintang kabupaten Aceh Besar untuk melihat bagaimana potensi pembangunan Pembangkit Listrik Tenaga Bayu (PLTB) di daerah tersebut. Penelitian ini dilakukan dengan cara menganalisa kecepatan angin berdasarkan data dari pengukuran anemometer menggunakan distribusi Weibull untuk tahun 2012 sampai 2015. Berdasarkan distribusi Weibull didapatkan bahwa parameter bentuk (k) yang diperoleh di kawasan Blang Bintang bernilai kecil yang bernilai sekitar 1.4 dan parameter skala (c) yang cenderung stabil bernilai sekitar 4. Dari nilai k dan c diperoleh bahwa kecepatan angin pada tahun 2012 yaitu sebesar 1 m/s dengan probabilitas 15%, tahun 2013 dan 2014 bernilai sebesar 0.5 m/s dengan probabilitas sebanyak 21% dan 19%, sedangkan untuk tahun 2015 sebesar 1 m/s sebanyak 17%. Study of the wind speeds in the region Blang Bintang, Aceh Besar district has been done to asses the potential of wind power instalation. The wind speed data was obtained from anemometer which has been instaling in that area. The datas were analyze by the Weibull distribution within the range for the years of  2012 to 2015. The results show that the shape parameter (k) is small, the value is around 1.4 and the scale parameter (c) tends to be stable, within the value of 4. Based on the value of k and c give that the wind speed in 2012 is equal to 1 ms-1 with a probability of 15%, in 2013 and 2014give the same value at 0.5 ms-1 with a probability of 21% and 19%, respectively while for 2015 is 1 ms-1 as much as 17%.

Dosen Pembimbing:1. Prof. Dr. Sunarmi, SH, MHum2. Dr. T. Keizerina Devi A, SH, CN, MHum3. Notaris Dr. Tony, SH, MKnMembers of the Board of Directors and the Board of Commissioners are limited company organs appointed for a certain period of time and can be reappointed, based on Article 94, paragraph 3 and Article 111, paragraph 3 of Law No. 40/2007 on Limited Liability Company. The research problems are how about the legal consequence of the action of the management of a limited liability company whose tenure has ended and is not validated by RUPS (General Shareholders’ Meeting), how about a Notary’s liability in making his Deed when the company’s management’s tenure has ended, and how about the legal solution for the management whose tenure has ended according to Law No. 40/2007 in Limited Liability Company. The research used juridical normative method. It also used the combination of Statute Approach and Case Approach.Keywords: Board of Directors and Board of Commissioners, Tenure, Notary’s Liability, Appointment of Management
