Judul: User Interface Optimization of MetalGO Digital Gold Investment Application to Improve Usability and User Experience
Abstrak: Investasi emas digital semakin diminati di Indonesia sebagai alternatif investasi yang aman dan mudah diakses. Namun, usabilitas dan pengalaman pengguna aplikasi MetalGO masih memerlukan peningkatan. Penelitian ini bertujuan meningkatkan usabilitas dan pengalaman pengguna aplikasi MetalGO dengan menggunakan metode The Wheel dalam dua iterasi, yang melibatkan evaluasi, analisis, desain, dan prototipe. Evaluasi iterasi pertama menunjukkan Maze Usability Score (MAUS) sebesar 62 dan System Usability Scale (SUS) sebesar 52,63, mengindikasikan usabilitas yang kurang baik. Redesain dilakukan dan iterasi kedua menunjukkan peningkatan dengan MAUS sebesar 84 dan SUS sebesar 71,13. User Experience Questionnaire (UEQ) juga menunjukkan peningkatan pada semua skala. Temuan ini menyimpulkan bahwa perbaikan antarmuka pengguna MetalGO berhasil meningkatkan usabilitas dan pengalaman pengguna secara signifikan, yang diharapkan dapat membuat aplikasi lebih populer dan banyak digunakan., Digital gold investment is increasingly popular in Indonesia as a safe and accessible investment alternative. However, the usability and user experience of the MetalGO application need improvement. This study aims to enhance the usability and user experience of the MetalGO application using The Wheel method in two iterations, involving evaluation, analysis, design, and prototyping. The first iteration's evaluation showed a Maze Usability Score (MAUS) of 62 and a System Usability Scale (SUS) score of 52.63, indicating poor usability. A redesign was conducted, and the second iteration showed improvements with a MAUS of 84 and a SUS score of 71.13. The User Experience Questionnaire (UEQ) also showed improvements across all scales. These findings conclude that the user interface improvements of MetalGO significantly enhanced usability and user experience, which is expected to make the application more popular and widely used.

Judul: Usability Evaluation of the Participatory-based KMS Sawit Mobile Application
Abstrak: KMS Sawit adalah aplikasi mobile yang dibuat dengan harapan dapat meningkatkan produktivitas perkebunan kelapa sawit rakyat Indonesia. Evaluasi usability perlu dilakukan terhadap aplikasi ini agar permasalahan yang dialami oleh pengguna pada saat menggunakan aplikasi dapat ditemukan. Pengujian usability pada penelitian ini dilakukan dengan menggunakan metode Concurrent Think Aloud dan System Usability Scale. Dengan pengujian Concurrent Think Aloud maka didapatkan hasil identifikasi masalah yang dialami pengguna pada saat pengujian. Perbaikan pada aplikasi dilakukan berdasarkan hasil rekomendasi perbaikan yang telah didapatkan dari hasil pengujian. Pengujian ulang dilakukan setelah aplikasi diperbaiki dan didapatkan hasil bahwa responden tidak mengalami permasalahan yang serupa. Skor keseluruhan SUS juga mengalami peningkatan pada pengujian ulang yaitu dari 71.667 menjadi 80.625., KMS Sawit is a mobile application created with the hope of increasing the productivity of Indonesian people's oil palm plantations. Usability evaluation needs to be done on this application so that the problems experienced by users when using the application can be found. Usability testing in this study was conducted using the Concurrent Think Aloud and System Usability Scale methods. With Concurrent Think Aloud testing, the problems experienced by users were obtained during testing. Improvements to the application were made based on recommendations that obtained from the test results. Retesting was carried out after the application was repaired and it was found that the respondents did not experience similar problems. The overall score of SUS also increased on the retest, from 71.667 to 80.625.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
