Judul: Perancangan Solusi Pengalaman Pengguna Aplikasi Pembelajaran Bahasa Isyarat Indonesia (Bisindo) untuk Teman Dengar
Abstrak: Kondisi tunarungu mengakibatkan gangguan dalam berkomunikasi dan kesulitan mendapatkan informasi. Hal ini mengakibatkan terhambatnya pemenuhan hak linguistik teman Tuli. Permasalahan ini dapat diatasi dengan bahasa isyarat yang memvisualisasikan kata melalui gerakan dan ekspresi wajah. Namun, masih sedikit masyarakat yang bisa berkomunikasi dengan bahasa isyarat karena kurangnya akses pembelajaran dan sosialisasi kepada masyarakat . Oleh karena itu, penelitian ini dilakukan untuk merancang sebuah medium-fidelity prototype aplikasi pembelajaran Bahasa Isyarat Indonesia (Bisindo) berdasarkan kebutuhan pengguna. Proses perancangan solusi mengadaptasi metode design thinking yaitu fase problem space dan solution space. Fase problem space dikerjakan dalam penelitian lainnya oleh rekan peneliti, kemudian fase solution space dilanjutkan pada penelitian ini dengan tahapan ideate; prototype; test; dan reflect. Hasil penelitian berupa mobile prototype berbasis pengalaman pengguna yang telah diujikan kepada lima orang responden. Penelitian dengan metode yang digunakan berhasil menjawab empat how might we yang didefinisikan. Perbaikan yang dilakukan pada iterasi kedua memberikan produk yang lebih baik kepada pengguna terlihat dari data kualitatif berupa usability problem yang ditemukan pada iterasi kedua lebih sedikit daripada iterasi pertama., Getting information is difficult for those who are deaf. This causes a delay in the realization of the deaf people's language rights. Using sign language, which visualises words through gestures and facial expressions, can help with this issue. However, only a few people can use sign language because of a lack of access to learning. This research was conducted to design a medium-fidelity prototype of an Indonesian Sign Language learning that prioritises user needs. The design process for this application adopts the design thinking method. The problem space phase was carried out in other studies by research colleagues. In this study, the solution space phase was continued in two iterations with the idea, prototype, test, and reflect stage. Output of the research is a mobile prototype based on user experience that has been tested on five respondents. Four how might we questions have been successfully answered by research. The qualitative data in the form of usability problems found in the second iteration compared to the first shows that improvements made in the second iteration deliver a better product to users.

Judul: Riset Pengalaman Pengguna Aplikasi Pembelajaran Bahasa Isyarat Indonesia (Bisindo) untuk Teman Dengar
Abstrak: Disabilitas rungu adalah gangguan pendengaran di mana seseorang tidak dapat mendengar suara sebagian atau keseluruhan. Orang dengan disabilitas rungu atau lebih sering disebut teman Tuli di Indonesia berkomunikasi dengan mengandalkan kemampuan visualnya. Bahasa isyarat menjadi media penghubung komunikasi antara teman Tuli dengan teman dengar. Teman Tuli di Indonesia menggunakan Bahasa Isyarat Indonesia (Bisindo) untuk berkomunikasi. Permasalahan yang dihadapi saat ini adalah jumlah teman dengar yang dapat memahami Bisindo masih sangat minim karena kurangnya akses pembelajaran dan sosialisasi Bisindo kepada masyarakat. Permasalahan tersebut mengurangi kesempatan teman Tuli memenuhi hak linguistiknya untuk menggunakan bahasa isyarat dengan status yang sama dengan bahasa lisan yang biasa digunakan oleh teman dengar. Oleh karena itu, penelitian ini dilakukan untuk memetakan kebutuhan teman dengar dalam melakukan pembelajaran Bisindo. Proses analisis kebutuhan ini dilakukan dengan metode design thinking. Hasil akhir dari penelitian ini adalah analisis kebutuhan teman dengar yang diimplementasikan dalam bentuk empathy map, user persona, customer journey map, how might we question, dan implikasi desain yang nantinya dapat digunakan untuk mengembangkan solusi pada fase solution space., Deafness is a hearing loss in which a person can’t hear partially or completely. Deaf person or more often called deaf friends in Indonesia communicate by relying on their visual abilities. Sign language is a communication link between deaf friends and hearing friends. Deaf friends in Indonesia use Indonesian Sign Language (Bisindo) to communicate. The problem faced nowaday is that the number of hearing friends who can understand Bisindo is still very minimal due to lack of access to learning and socialization of Bisindo to the community. This problem reduces the opportunity for deaf friends to fulfill their linguistic rights to use sign language with the same status as the spoken language commonly used by hearing friends. Therefore, this research was conducted to map the needs of hearing friends in doing Bisindo learning. This process is carried out using the design thinking method. The final result of this research is an analysis needs of hearing friends which is implemented in the form of an empathy map, user persona, customer journey map, how might we question, and design implications which can be used to develop solutions in the solution space phase.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
