Judul: Rancang Bangun Arsitektur Penanganan Dini Mualaf pada Aplikasi Hijrah ID dengan Metode UML Development System
Abstrak: Berdasarkan data dari Mualaf Center Indonesia bahwa tren mualaf tiap tahun meningkat dengan persentase sekitar 31,2% selama 4 tahun terakhir. Tantangan dan hambatan dialami mualaf antara lain adanya ancaman atau intimidasi dari keluarga atau kerabat dekat sehingga menyebabkan kondisi psikologis mualaf menjadi terganggu dan menghambat proses belajar agama Islam. Hijrah ID adalah sebuah aplikasi berbasis Android yang memberikan layanan untuk penanganan dini bila hal-hal yang tidak diinginkan terjadi pada mualaf serta pembelajaran mengenai agama Islam. Metode pengembangan aplikasi HIJRAH ID menggunakan UML Development System. Hijrah ID memiliki lima fitur utama di dalamnya, yakni fitur Ta’shil, Konsultasi, Artikel, Jadwal Kajian, dan Panic Button. Hasil dari penelitian ini berupa rancangan prototipe Panic Button. Panic Button merupakan suatu layanan untuk membantu mualaf ketika sedang memerlukan bantuan yang harus ditindak secara cepat tanggap sehingga harapannya mengurangi tindakan yang tidak diinginkan. Panic Button menghubungkan mualaf dengan ustaz berdasarkan posisi saat menekan panic button dan memberikan perizinan oleh ustaz.

Judul: Designing Zakat Learning Interactions for Mualaf in Hijrah Id Apps with The Wheel Method
Abstrak: Penelitian ini dilakukan untuk merancang interaksi belajar zakat bagi mualaf dengan menggunakan metode the Wheel yang diperkenalkan oleh Hartson dan Pyla. Aplikasi Hijrah Id versi 1 telah dikembangkan oleh beberapa personil civitas departemen Ilmu Komputer IPB yang bekerja sama dengan Mualaf Center Baznas. Penelitian ini dilaksanakan dengan empat tahap yaitu: understand needs, design solutions, prototype candidates dan evaluate UX. Penelitian diawali dengan tahapan understand needs melalui interview dengan lima orang pembina mualaf. Revisit ke tahapan evaluate UX dengan pengujian usability aplikasi Hijrah Id versi 1 kepada tiga orang mualaf dengan tingkat keberhasilan sebesar 90,5%. Tahapan understand needs kedua dilakukan dengan interview kepada empat orang mualaf. Hasil akhir penelitian ini berdasarkan tahapan design solutions dan prototype candidates berupa analisis perilaku dan kebutuhan mualaf yang direpresentasikan dalam bentuk user persona, user story, storyboard serta rancangan interaksi belajar zakat pada mualaf dalam bentuk medium-fidelity prototype., This research was conducted to test the usefulness of the Hijrah Id application and the interaction of zakat learning interactions for converts using The Wheel method introduced by Hartson and Pyla. The Hijrah Id application version 1 has been developed by several personnel of the Computer Science department of IPB in collaboration with the Mualaf Center of Baznas. This research was carried out in four stages, namely: understand needs, design solutions, prototype candidates and evaluate UX. The study began with the stage of understanding needs through interviews with five converts. Revisit to the UX evaluate stage by testing the usability of the Hijrah Id application version 1 for three converts with a success rate of 90,5%. The second understanding needs stage was carried out by interviewing four converts. The final results of this study were based on the stages of design solutions and prototype candidates in the form of an analysis of the behavior and needs of converts. The final result of this study is based on the solution design stage and prototype candidate in the form of behavior analysis and needs of converts which are represented in the form of user personas, user stories, storyboards, and the design of zakat learning interactions for converts in the form of a medium-fidelity prototype.

Judul: Variabilitas Klorofil-a dan Interelasinya Terhadap ENSO (El Niño Southern Oscillation) Di Perairan Utara Papua.
Abstrak: This research aimed to study the variability of surface chlorophyll-a and its interrelation to ENSO (El Nino Southern Oscillation) in the North Papua waters. Monthly averaged data of Nino 3.4 Index from CPC NOAA, sea surface temperature (SST) from ERSL NOAA, and surface chlorophyll-a from Globcolor Project were analyzed using FFT (Fast Fourier Transform) and wavelet methods during September 1997 - April 2009. Referring to temperature anomaly at Nino region 3.4 during the period this study, three El Nino events were taken place in 1997/1998, 2002/2003, and 2004/2005. The 1997/1998 El Nino was the strongest with temperature anomaly reaching +2,69 oC, while from twice La Nina events (1998/1999/2000, 2007/2008), the 2007/2008 La Nina showed the weakest temperature anomaly at -1,89 oC. During 1997/1998 El Nino, SST in the North Papua waters was decreasing to range 29,48 - 29,72 oC, compared to its normal range of 30,05 - 30,33 oC. On the contrary, surface chlorophyll-a was increased to 0,088 – 0,391 mg/m3 during 1997/1998 El Nino, while low range of chlorophyll-a was observed during 2007/2008 La Nina (0,062 – 0,140 mg/m3 Keywords: chlorophyll-a, sea surface temperature, El Nino, inter-annual signal, North Papua ). During El Nino, hotspot of chlorophyll-a was shifted from west to east and following the movement of warm pool. Power spectrum density of chlorophyll-a revealed dominant inter-annual signal compare to annual and semi-annual. Cross-correlation analysis between Nino 3.4 with chlorophyl-a variability showed strong coherence at inter-annual signal which presumed as El Nino, in where the rise of chlorophyll-a was observed 1 - 3 month after El Nino event.
