Judul: Analysis of User Experience Related to the use of the Large Language Model (LLM) for the Agricultural Community
Abstrak: Salah satu cara dalam mengatasi tantangan petani dalam mencari informasi secara efisien di internet adalah penggunaan chatbot yang dapat diimplementasi menggunakan Large Language Model (LLM) seperti ChatGPT. Pengalaman yang diberikan LLM dapat memengaruhi pengalaman pengguna yang berkaitan dengan kenyamanan dan kepuasan. Cara untuk menilai sejauh mana peran LLM dalam memberikan pengalaman pengguna yang baik adalah dengan melakukan penelitian menggunakan kuesioner dan wawancara untuk menilai informasi yang diberikan LLM dari aspek kepercayaan, pemahaman, dan gaya komunikasi. Kuesioner dibuat berdasarkan wawancara kepada petani dan penyuluh pertanian serta jawaban dari ChatGPT dan dosen pertanian yang dibagikan kepada 11 petani di Kecamatan Dramaga. Sebanyak 6 responden di antaranya diwawancara untuk menjelaskan hasil kuantitatif. Hasilnya, jawaban dari dosen lebih unggul dalam segala aspek. Meskipun demikian, rata-rata respon positif setiap jawaban LLM bernilai cukup tinggi. Akan tetapi, masih ada beberapa kekurangan informasi dari LLM seperti panjang informasi dan penggunaan kata-kata yang dianggap masih asing oleh responden., One way to overcome farmers' challenges in finding information efficiently on the internet is using chatbot that can be implemented using Large Language Model (LLM) such as ChatGPT. The experience provided by the LLM can influence the user experience in terms of comfort and satisfaction. The way to assess the extent of the LLM's role in providing a good user experience is to conduct research using questionnaires and interviews to assess the information provided by the LLM in terms of trust, understanding, and communication style. The questionnaire was made based on interviews with farmers and agricultural extension workers, also responses from ChatGPT and agricultural lecturers, and was distributed to 11 farmers in Dramaga District. A total of 6 respondents were interviewed to explain the quantitative results. The results showed that the responses from the lecturers were superior in all aspects. Nevertheless, the average positive response of each LLM response was quite high. However, there were still some shortcomings in the information provided by the LLM, such as the length of information and the use of unfamiliar words for respondents.

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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
