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: Perancangan User Experience Aplikasi Digitani untuk Penyuluh Pertanian Menggunakan Metode Five Planes
Abstrak: Pembangunan pertanian membutuhkan kompetensi dari pengguna teknologi. Pihak yang masih kurang terhadap akses sumber informasi yaitu petani sehingga diperlukan dukungan sumber daya penyuluh pertanian. Institut Pertanian Bogor sebagai lembaga pendidikan di bidang pertanian mengembangkan aplikasi Digitani yang membantu dalam penyebaran informasi. Namun, belum sepenuhnya melibatkan penyuluh pertanian. Perancangan aplikasi menggunakan metode Five Planes. Penelitian ini bertujuan untuk meningkatkan user experience aplikasi Digitani berdasarkan kebutuhan penyuluh pertanian menggunakan Retrospective Think Aloud. Evaluasi dilakukan kepada lima responden dengan melakukan pengujian pada 17 task. Hasil evaluasi menunjukkan error rate yang paling tinggi terdapat pada task menyimpan dan membuka artikel yang disimpan sebesar 67% serta terdapat 6 task mobile dan 3 task website yang pengerjaannya melebihi batas waktu yang ditentukan. Secara keseluruhan responden berpendapat bahwa fitur yang diujikan sudah mencakup kebutuhan penyuluh pertanian., Agricultural development requires competence from technology users. Farmers, who still lack access to information sources, require the support of agricultural extension resources. Bogor Agricultural University, as an educational institution in agriculture, developed the Digitani application to help disseminate information. However, agricultural extension workers have not been fully involved in the application's design. The design of the application incorporates the Five Planes method. This research aims to improve the user experience of the Digitani application based on the needs of agricultural extension workers using Retrospective Think Aloud. The evaluation was conducted on five respondents by testing 17 tasks. The evaluation results show that the task of saving and opening stored articles has the highest error rate at 67%, and there are 6 mobile tasks and 3 website tasks that exceed the specified time limit. Overall, respondents believed that the tested features adequately addressed the needs of agricultural extension workers.

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.
