Abstract

Penyebaran berita hoax di era digital menjadi tantangan serius yang memerlukan solusi berbasis teknologi untuk mengidentifikasi dan meminimalkan dampaknya. Penelitian ini bertujuan untuk mengevaluasi performa Logistic Regression (LR) dan Random Forest (RF) dalam mendeteksi berita hoax menggunakan representasi teks berbasis Term Frequency-Inverse Document Frequency (TF-IDF). Hyperparameter tuning diterapkan pada kedua algoritma untuk meningkatkan akurasi, precision, recall, dan F1-score. Dataset yang digunakan terdiri dari berita hoax dan valid dalam bahasa Indonesia, yang telah melalui tahapan preprocessing, termasuk pembersihan teks, penghapusan stopwords, dan stemming. Hasil evaluasi menunjukkan bahwa Logistic Regression, setelah tuning, mencapai akurasi sebesar 95.20%, precision 95.71%, recall 94.48%, dan F1-score 95.09%. Random Forest menunjukkan akurasi sebesar 92.39%, precision 94.39%, recall 89.87%, dan F1-score 92.08%. Logistic Regression unggul dalam keseimbangan antara precision dan recall, sementara Random Forest menunjukkan kekuatan pada precision dengan kemampuan menangani pola data yang lebih kompleks. Teknik TF-IDF terbukti efektif dalam memberikan bobot pada kata-kata yang relevan, membantu algoritma klasifikasi dalam mengenali pola dalam data teks. Penelitian ini juga memiliki dampak praktis dalam memberikan fondasi bagi pengembangan sistem deteksi hoax yang dapat digunakan di aplikasi berbasis NLP, baik untuk kebutuhan akademis maupun implementasi di industri. Penelitian ini berkontribusi pada pengembangan sistem deteksi hoax berbasis Natural Language Processing (NLP), khususnya untuk bahasa Indonesia. Untuk pengembangan lebih lanjut, disarankan memperluas dataset dengan sumber berita yang lebih beragam dan mengeksplorasi algoritma berbasis deep learning seperti LSTM atau Transformer. Secara ilmiah, penelitian ini memberikan kontribusi penting dengan menguji efektivitas hyperparameter tuning dalam meningkatkan akurasi model deteksi hoax. Hasil penelitian ini diharapkan dapat menjadi acuan dalam membangun sistem deteksi hoax yang lebih akurat dan andal.

Abstract

This study aims to analyze the level of corn farmers' participation in agricultural extension programs and the factors influencing it in the Porehu District. Employing a survey method with a descriptive analysis approach and a quantitative paradigm, the study involved 112 corn farmers as respondents. The results indicate that internal factors such as age, education, farming experience, income, and family dependents significantly impact farmers' participation in extension activities. Additionally, external factors including farmers' motivation, perception of extension, support for infrastructure, support from extension agents, and social environment support also significantly affect farmers' participation. These findings highlight the need to develop more effective and inclusive extension strategies and strengthen collaboration among the government, agricultural extension agents, farmer organizations, and other relevant stakeholders. Such efforts are expected to enhance farmer participation and the success of agricultural extension programs, ultimately positively impacting agricultural productivity and farmers' well-being.

Abstract

This research aims to: (1) find out the initial effects the use of the mixed borax and boric acid as a wood preserving material against termite attacks observed visually and based on its weight loss, and (2) find out the soaking duration and the mixed borax and boric acid concentration which have the most effective initial effects to preserve wood. The research method applies an experimental approach. The research samples are sengon woods of 5/7-15 cm and the wood preserver of the mixed borax and boric acid. The ratio of the mixed borax and boric acid concentration is 1.54 to 1.00. The preserving material concentration of 5% applies to the 15 testing samples of group A, 7.5% to the 15 testing samples of group B, and 10% to the 15 testing samples of group C. Each testing sample is treated with soaking for 1 hour, 2 hours, and 3 hours. As a control group is the 5 testing samples of group D. The research data of the visual observation are collected by a field direct observation for 48 days, while the weight loss data of each testing sample of each treatment are collected by weighing in the Construction Material Laboratory. The research data are analyzed using the quantitative descriptive technique. The research result visually shows that among all testing samples, the most extreme condition and eaten by termites exists on group D without any treatment. Based on the weight loss of each testing sample, obviously group D is eaten by termites of the largest persentage compared to the treatment A, B, and C. The soaking treatment difference does not appear on the treatment A with the preserving material concentration of 5%. However, the soaking duration of the treatment B (7.5%) and C (10%) have very good initial effects against wood termite attacks, especially group C with the soaking duration of 3 hours. Generally, the initial effects of the chemical preserving material of the mixed borax and boric acid as a wood preserving material, especially of the treatments A, B, and C, have good effects against termite attacks. Among the three treatments, the treatment C with the preserving material concentration of 10% and the soaking duration of 3 hours is the most effective one against wood termite attacks. Keywords: wood preserving, borax, boric acid, and termite

Abstract

This study explores the implementation of the Triple Helix model in strengthening research-based human resources through the strategic partnership between Universitas Negeri Yogyakarta (UNY), industry, and government. The Triple Helix framework posits that innovation and human capital development emerge from synergistic interactions among universities, industry, and government, each contributing unique resources, knowledge, and policy support. At UNY, this partnership is realized through collaborative research projects, technology transfer, curriculum alignment with industrial needs, and policy facilitation aimed at fostering employability and research competence of graduates. The university serves as a knowledge hub that generates research and innovation, while industries provide practical expertise, funding, and employment opportunities, and the government ensures regulatory support and incentives. This paper analyzes case studies of collaborative programs, highlighting mechanisms such as joint research centers, internships, scholarships, and community service initiatives that integrate research into human resource development. The findings demonstrate that the Triple Helix model fosters mutual benefits: UNY enhances its academic relevance and societal impact, industries gain access to skilled and innovative talent pools, and the government achieves policy goals related to national development and workforce competitiveness. The study also identifies challenges, including misaligned expectations, bureaucratic barriers, and funding sustainability, and proposes recommendations for strengthening the governance of partnerships and aligning stakeholder objectives. Overall, the research concludes that the Triple Helix partnership at UNY exemplifies a promising model for advancing research-based human resources that are adaptive, innovative, and responsive to dynamic industrial and societal needs. This model underscores the importance of sustained communication, trust, and shared vision among stakeholders to optimize the outcomes of such collaborations in the Indonesian context and beyond.

Abstract

The Indonesian capital markets have undergone a notable transformation, shifting from a savings-oriented society to one that is increasingly investment-oriented. This shift is particularly evident among Generation Z, who now constitute the majority of investors. In the Berau Regency of East Kalimantan Province, there has been a significant rise in individual stock ownership, reflecting a growing investment interest, especially among younger demographics. This study, conducted using Structural Equation Modeling (SEM) analysis with SmartPLS, examined 203 participants from the Generation Z population in Berau Regency. The findings indicate that financial literacy—encompassing knowledge of personal finance, savings, loans, insurance, and investment—along with financial behavior, plays a critical role in shaping an individual's investment preferences. Additionally, investment expertise was found to be advantageous for investors. However, minimum capital requirements and return on investment were not significant factors influencing investment preferences. In contrast, risk perception positively impacted investment preferences, with considerations spanning financial, social, performance, time, and psychological factors. These results provide valuable insights into the factors influencing investment interest in the capital market, particularly among young investors. To enhance the objectivity and applicability of future research, it is recommended to account for respondents' characteristics, geographical conditions, and more representative samples, as these factors may yield different outcomes.
