Judul: Peningkatan Kualitas User Experience Aplikasi Digitani bagi Petani dengan Metode Five Planes
Abstrak: Pada era digital, petani bisa memanfaatkan berbagai teknologi untuk menambah wawasan untuk mengolah berbagai sumber daya dan mengatasi masalah yang menghambat kemajuan pertanian di Indonesia. IPB University menghadirkan sebuah aplikasi Digital Tani (Digitani) dengan tujuan untuk memfasilitasi pertukaran informasi tentang pertanian antara petani, penyuluh pertanian, dan akademisi IPB. Digitani dapat diakses melalui mobile maupun web. Dalam rangka peningkatan user experience, dibutuhkan penelitian mengenai eksplorasi fitur pada Digitani, lalu mengetahui kebutuhan petani yang dapat diterapkan pada aplikasi Digitani. Penelitian yang dilakukan menggunakan metode Five Planes. Hasil penelitian ini menghasilkan user persona, 10 spesifikasi fungsional, low-fidelity prototype, dan high-fidelity prototype. Evaluasi dilakukan kepada 5 responden dengan metode Retrospective Think Aloud. Evaluasi menunjukan error rate tertinggi pada task membaca dan menyimpan artikel sebesar 60% serta terdapat 7 task yang pengerjaanya melewati batas waktu. Evaluasi akan menjadi rekomendasi untuk perbaikan pada pengembangan aplikasi Digitani selanjutnya. Responden merasa prototipe yang dibuat sudah memenuhi kebutuhan petani dalam pertanian., In the digital era, farmers can utilize various technologies to broaden their insights in managing diverse resources and addressing challenges that hinder agricultural progress in Indonesia. IPB University introduces a Digital Farming application (Digitani) with the aim of facilitating the exchange of agricultural information among farmers, agricultural extension officers, and IPB academics. Digitani can be accessed through mobile devices as well as the web. To enhance user experience, research is conducted to explore the features of Digitani and identify farmer's needs that can be integrated into the application. The research employs the Five Planes method, resulting in a user persona, 10 functional specifications, a low-fidelity prototype, and a high-fidelity prototype. Evaluation is conducted with 5 respondents using the Retrospective Think Aloud method. The evaluation indicates the highest error rate in the task of reading and saving articles at 60%, along with 7 tasks exceeding the time limit. The evaluation will serve as recommendations for improvements in the subsequent development of the Digitani application. Respondents feel that the created prototype adequately fulfills farmer's needs in agriculture.

Judul: Perancangan Pengalaman Pengguna Aplikasi Digitani Menggunakan Metode Five Planes untuk Pakar Pertanian IPB
Abstrak: Institut Pertanian Bogor telah merilis aplikasi Digitani berbasis mobile dan web untuk memfasilitasi konsultasi antara petani dan pakar pertanian IPB. Namun, aplikasi tersebut belum melakukan analisis mendalam mengenai kebutuhan pakar. Padahal, pakar pertanian IPB berperan penting dalam menyebarkan ilmu-ilmu pertanian. Oleh karena itu, dilakukan penelitian yang berfokus pada perancangan prototipe mobile dan web aplikasi Digitani sesuai dengan kebutuhan pakar IPB menggunakan metode Five Planes. Hasil penelitian ini meliputi user persona, 11 spesifikasi fungsional, low-fidelity prototype, dan high-fidelity prototype. Prototipe dievaluasi menggunakan metode Retrospective Think Aloud kepada lima responden dengan jumlah 20 task. Evaluasi menunjukkan error rate tertinggi terjadi pada pengerjaan task mobile sebesar 70%. Terdapat dua task pada mobile dan satu task pada web yang pengerjaannya melampaui batas waktu yang ditentukan. Evaluasi ini menjadi saran untuk perbaikan pada prototipe selanjutnya. Secara keseluruhan, responden menilai bahwa desain aplikasi Digitani menarik dan mudah digunakan., Bogor Agricultural University has released a mobile and web-based Digitani application to facilitate consultation between farmers and IPB agricultural experts. However, the application has not conducted an in-depth analysis of expert needs. In fact, IPB agricultural experts play an important role in disseminating agricultural sciences. Therefore, research was conducted that focused on designing mobile and web prototypes of the Digitani application according to the needs of IPB experts using the Five Planes method. The results of this research include user personas, 11 functional specifications, low-fidelity prototype, and high-fidelity prototype. The prototype was evaluated using the Retrospective Think Aloud method to five respondents with a total of 20 tasks. The evaluation showed that the highest error rate occurred in the mobile task at 70%. Then, there were two tasks on mobile and one task on the web that exceeded the specified time limit. This evaluation is a suggestion for improvement in the next prototype. Overall, respondents found the design of the Digitani app attractive and easy to use.

Abstrak: Greenback mullet (Chelon suviridis) belong to family of Mugilidae. Greenback mullet have a high economic value in Karangsong water. Information of C. subviridis in this location is limited, whice is necessary to study on reproduction for its management. Through this study, reproduction pattern of C. subviridis in Karangsong water are determined. The study was conducted from December 2012 to May 2013. Total number of fishes that taken during the study was 336 individuals. The results showed that the sex ratio between males and females is 1:2,03 with Chi-square test. Condition factors ranged from 0,6881 to 0,8377 %. Greenback mullet males mature more rapidly that females with mature gonad of 114 mm for male and 102 mm for female. Peak spawning season of C. subviridis in the waters of Karangsong. Greenback mullet is thought to occur in early February. Reproductive potential of C. subviridis is quite large in the amount of 9.691 to 173.335 eggs. Eggs diameter of C. subviridis ranged from 0,18 to 0,75 mm with the mode of spread of two types of spawning peaks with partial (partial spawner).
