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: 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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
