Abstract

The livestock subsector, particularly broiler chickens, provides animal protein sources in Indonesia. However, low production efficiency, managerial challenges, and productivity fluctuations remain the primary obstacles to achieving sustainability in this sector. This study aims to analyze the success rate of broiler chicken production at PT. Jandela Jaga Kaloka (JAJAKA) using a data mining classification approach with the K-Nearest Neighbors (K-NN) and Naive Bayes algorithms. The research population comprises broiler production data from various branches of PT. JAJAKA, with a sample of 200 datasets selected based on representative criteria. The study employs the hold-out method with data splits of 60:40 and 70:30 for training and testing the models. The success rate of production is classified into three categories: good, less good, and excellent. The findings reveal that the K-NN algorithm outperforms with an accuracy of 92.59%, compared to Naive Bayes, which achieves 76.67%. Regarding recall, K-NN records a value of 96.67%, higher than Naive Bayes at 71.67%. However, Naive Bayes shows slightly better precision (94.29%) than K-NN (93.55%). These results affirm that the K-NN algorithm is more effective for classifying the success rate of broiler chicken production, supporting PT. JAJAKA in making more precise and strategic managerial decisions. Furthermore, this study contributes significantly to developing data mining methods in the poultry farming sector to improve efficiency and productivity sustainably. It provides valuable insights for PT. Jandela Jaga Kaloka will evaluate the success rate of broiler chicken production, facilitating more accurate managerial decision-making.

Abstract

The issue in this research is the lack of understanding regarding the main topics and their changes in speeches and media publications related to President Joko Widodo. This study aims to identify, analyze, and predict changes in key topics within speeches, statements, and media publications related to President Joko Widodo using Latent Dirichlet Allocation (LDA) topic modeling techniques. The research employs a quantitative approach to analyze President Joko Widodo's speech texts using the Latent Dirichlet Allocation (LDA) method. The process began with scraping documents from the official website of the Republic of Indonesia's Secretariat, resulting in 5,988 speech transcripts from October 20, 2014, to March 2, 2024. Text preprocessing involved tokenization, stopword removal, and stemming/ lemmatization, followed by dictionary-term formation. The findings indicate that the model with k=16 has the highest coherence (0.554) and the best perplexity at k=21 (-13.130). The main topics identified include Nationalism and National Values, Regional Government, and Education and Children. Topic visualization with PyLDAvis aids in the exploration and identification of topics, providing insights for decision-making and policy development. To enhance understanding of topic changes, it is recommended to conduct trend analysis on key topics over time. This will help identify how President Joko Widodo's priorities shift and respond to new issues. By monitoring these trends, the research can provide deeper insights into the evolution of policies and the President's focus.

Abstract

Disasters are unexpected and potentially significant risks to the continuity of company and organization operations, especially those related to information systems and information technology (IS/IT). The Internal Audit Education Foundation (YPIA) in handling disasters related to data and information security often faces obstacles that cause problems that become more widespread in the future. Therefore, a disaster recovery plan (DRP) becomes an urgent need. The purpose of this study is to evaluate resilience to disasters and data and information security attacks, and to ensure better business continuity in the face of emergency situations. Researchers use the National Institute of Standards and Technology (NIST) Framework in conducting a DRP analysis of security and data. The study begins by identifying and evaluating risks, conducting risk assessments, conducting Business Impact Analysis (BIA) determining preventive controls, and formulating contingency strategies. This study produces priority handling of high maturity risks in data damage, with an initial risk value of 3.8 and an impact of 4.4. After the control was carried out, there was a residual risk with a risk value of 1.6 and an impact of 3, with a very low maturity level and a residual value of 13.5 (80%). The reduction in the risk of data damage was significant with a very low residual value, indicating that the implementation of DRP using the NIST Framework in risk mitigation on critical assets of the Internal Audit Education Foundation was quite effective.
