ABSTRAK
Organisasi memerlukan karyawan yang memiliki engagement terhadap organisasinya. Salah satunya dengan melihat peran karier untuk menumbuhkan engagement karyawan. Oleh sebab itu, diperlukan studi yang dapat menjelaskan keterkaitan antar variabel dan menguji intervensi yang dapat dilakukan berdasarkan hasil studi tersebut. Penelitian ini terdiri dari dua studi, studi satu bertujuan untuk meneliti pengaruh proactive career behavior pada work engagement. Dalam penelitian ini, digunakan UWES-9 untuk mengukur work engagement dan Proactive Career Behavior Items untuk mengukur proactive career behavior. Data dari 27 responden diolah menggunakan uji regresi, menunjukkan hasil bahwa proactive career behavior memprediksi work engagement (F (1,70) = 13.85, p < .05, R2 = .17). Berdasarkan hasil penelitian tersebut, peneliti melakukan studi dua menggunakan desain before after dengan menyusun intervensi yang dinamakan My Success Story Program. My Success Story Program diberikan melalui workshop dan coaching yang bertujuan untuk meningkatkan proactive career behavior, yang diharapkan dapat meningkatkan work engagement. Program intervensi diberikan pada 11 partisipan yang memiliki skor variabel rendah. Hasil evaluasi pembelajaran menunjukkan terdapat perbedaan yang signifikan (Z = -2.40, p < .05) dan terdapat perubahan evaluasi perilaku yang signifikan (Z = -2.94, p < .05). Hasil uji beda pre¬ dan post variabel menunjukkan bahwa terdapat peningkatan yang signifikan pada variabel proactive career behavior dan work engagement (p < .05). Oleh karena itu, My Success Story Program dapat meningkatkan proactive career behavior dan work engagement di PT X.

ABSTRACT
Organizations need employees who engaged within organization. One of the ways is by looking at career roles to foster engagement. Therefore, it needed research that can explain the relationships between the two variables and examine intervention that can be done based on those results. This research consisted of two studies, study 1 aimed to examine the effect of proactive career behavior on work engagement. In this study, UWES-9 was used to measure work engagement and Proactive Career Behavior Items to measure proactive career behavior. Data from 27 respondents were processed using regression, showing that proactive career behavior predicted work engagement (F (1.70) = 13.85, p <.05, R2 = .17). Based on that, researchers conducted a study 2, using before after design to developing an intervention called My Success Story Program. My Success Story Program is provided through workshops and coaching session that aim to increase proactive career behavior and work engagement. The intervention was given to 11 participants who had low variable scores. The results of the learning evaluation showed a significant difference (Z = -2.40, p <.05) and there was a significant change in behavior evaluation (Z = -2.94, p <.05). The results of the pre and post variable difference showed that there was a significant increase in proactive career behavior and work engagement (p <.05). Therefore, My Success Story Program succeeded to increasing proactive career behavior and work engagement at PT X.

Penelitian-penelitian tentang kapasitas reverse link sistem wireless code division multiple access (CDMA) kurang menunjukkan kapasitas yang sebenamya karena hanya memperhitungkan pengaruh ketidak-sempurnaan pengendalian daya oleh shadowing hanya pada homecell (sel sendiri) saja atau pada sel-sel tetangga saja. Pada kenyataannya, shadowing pasti terjadi antara base station (BS) and mobile station (MS). Oleh karena itu tesis ini menganalisa secara matematis kapasitas reverse link sebuah sistem wireless CDMA yang mendukung layanan suara (kelas-1) dan data (kelas-2) secara terpadu dengan memperhatikan pengaruh pengendalian daya karena shadowing pada sistem selular dua-tier. Selain itu, pengaruh aktifitas suara dan variable spreading gain dari user kelas-2 terhadap kapasitas user kelas-1 dan pengaruh sektorisasi terhadap kapasitas kedua layanan tersebut juga dianalisa. Dari pengamatan dan analisa yang telah dilakukan menunjukkan bahwa faktor yang berpengaruh terhadap kapasitas sistem wireless CDMA diantaranya faktor aktifitas user, sektorisasi dan shadowing. Dengan pengendalian daya reverse link, apabila downlink shadowing lebih besar dari pada uplink shadowing, user akan mengirimkan daya lebih besar dari yang dikehendaki BS sehingga menimbulkan interferensi sesama user di BS. Interferensi juga dapat berasal dari user lain yang memiliki bit rate lebih besar (spreading gain kecii) karena bit rate yang besar rnemerlukan daya yang besar. Penurunan kapasitas karena shadowing sampai dengan 4 dB dapat diatasi dengan sektorisasi sel.

The existing researches on the reverse link capacity of a wireless code division multiple access (CDMA) system did not exactly represent its reverse link capacity. These were because they considered that the effect of shadowing was experienced by a home cell or other cells only. In fact, the shadowing absolutely exists between base station (BS) and mobile station (MS). So, this thesis mathematically analyzes the reverse link capacity of a CDMA system which supports integrated services (voice - class-1 and data -- class-2) that considers power control due to shadowing in a two tiers of a cellular system. In addition, the effect of variable spreading gain of class-2 users on class-1 users' capacity and by dividing cells into sectors are also observed. Observations and analyses show that some factors which determine the capacity of a wireless CDMA system such as user activity factor, sectorization and shadowing. In a reverse link power control, if downlink shadowing is higher than uplink shadowing, user will transmit power more than its actually required by the BS, so this power will cause interference to others. On the other hand, interference also comes from users who have a signal with a higher bit rate (has a small spreading gain) because a higher bit rate also requires a higher power. Capacity decaying due to shadowing up to 4 dB can be solved by using a cell sectorization.
