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: Effect of CaSO4.2H2O (coagulant) concentration and temperature on the protein coagulation process and curd texture
Abstrak: Texture is an important aspect to determine consumer preferences for products based curd, one of them is tofu. Differences in texture of are influenced by the parameters of the coagulation process which consists of coagulant concentration and coagulation temperature. Effect of differences in coagulation parameters was represented by the data of whey transmittance, whey protein content, pH value of whey, curd protein profiles, moisture content and total solids of curd, and curd texture (objectively by TPA devices). This study used CaSO4.2H2O as a coagulant for soybean milk with the concentration of 0.015 N (A), 0.030 N (B), and 0.045 N (C). Soy milk was coagulated at the temperature of 60 and 80°C. Coagulation produced curd tofu and whey. The data suggest that whey C had the highest transmittance [23.52% (60°C) and 19.30% (80°C)], whey protein B had the lowest [0.448 mg/mL (80°C) and 0.390 mg/mL (60°C )], while the whey pH values were not significantly different in the range of 5.72 to 5.90. The curd C had the highest moisture content (wet basis) [20.63% (80°C) and 18.69% (60°C)] and the highest total solids/yields (raw material basis) [40.88% (60°C) and 37.75% (80°)]. The function f(x) = y = 2.896x + 1358 was obtained to correlate the curd texture by objective measurement (x) and the sensory evaluation (y). Curd C (80°C) had the highest hardness 2.474 (slightly hard) while the curd A (60°C) had the lowest hardness 1.164 (soft). Meanwhile, the curd protein profiles consists of 7S globulin (β-conglycinin) and 11S globulin (glycinin) protein subunits. The 7S protein consists of subunits α, α’, and β, while the 7S protein consists of the acid subunits (A1, A2, A4, A6) and the base subunit. Percent of 11S subunits in the curd increased with increasing concentration of coagulant in all the coagulation temperature. The percent of 7S subunits indicated otherwise, as well as its components, α+α’ and β. Overall, subunits of proteins that have an influence on the texture are the A1 subunit and the base subunit of the 11S proteins with the highest Pearson correlation on the curd cohesiveness.
