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: Independence and Vulnerability of Deaf Consumer in Banking Financial Services
Abstrak: Keterbatasan pendengaran dan komunikasi akan berdampak pada perlakuan dan pelayanan yang diterima oleh konsumen Tuli, seperti perbankan. Penelitian ini bertujuan untuk menganalisis hubungan dan pengaruh karakteristik dan kemandirian responden terhadap kerentanan konsumen Tuli pengguna layanan perbankan. Penelitian ini menggunakan mix methods. Penelitian kuantitatif menggunakan purposive sampling dengan menyebarkan kuesioner kepada 70 responden Tuli berusia lebih dari sama dengan 17 tahun dan pernah mengakses layanan perbankan selama tiga tahun terakhir secara mandiri. Desain kualitatif dilakukan dengan wawancara mendalam kepada lima responden Tuli di komunitas Diffable Action Kota Bogor. Riset menunjukkan bahwa usia dan riwayat Tuli memiliki hubungan positif signifikan dengan kemandirian. Pendidikan memiliki hubungan negatif signifikan dengan risiko kerugian. Riwayat Tuli dan kemandirian memiliki hubungan positif signifikan dengan kerentanan konsumen. Hasil uji regresi menunjukkan bahwa semakin mandiri konsumen Tuli, maka semakin rentan dalam mengakses jasa perbankan. Selain itu, konsumen Tuli sejak lahir memiliki peluang kerentanan yang tinggi daripada konsumen Tuli tidak sejak lahir., Hearing and communication limitations will impact the treatment and services received by deaf consumers, such as banking. This study aims to analyze the relationship and influence of respondents' characteristics and independence on the vulnerability of deaf consumers who use banking services. This research uses mixed methods. Quantitative research uses purposive sampling by distributing questionnaires to 70 deaf respondents who are more than 17 years old and have independently accessed banking services for the last three years. The qualitative design was carried out by in-depth interviews with five deaf respondents in the Diffabel Action community in Bogor City. Research shows that age and deafness profile has a significant positive relationship with consumer independence. Education has a significant negative relationship with the risk of loss. Deafness profile and independence have a significant positive relationship with consumer vulnerability. The results of the regression test show that the more independent Deaf consumers are, the more vulnerable they are to accessing banking services. In addition, deaf consumers from birth have a higher chance of vulnerability than deaf consumers not from birth.

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.
