Get PDFIn the global movie industry, subtitles are essential as they bridge the communication between the story of a movie and the global audiences. Therefore, subtitling translators must provide accurate translations of subtitles so that the audience can understand the story of a movie. This descriptive-qualitative research aims to analyze the types of interrogative sentences, translation techniques, and the accuracy of the interrogative sentences’ translations in the subtitles of the first two episodes of the Wanda Vision series through content analysis and focus group discussion. The results of this study found 130 data classify into 3 types of interrogative sentences based on Quirk et al. (1985): Yes-no questions, WH questions, and Alternative Questions. In translating these interrogative sentences, there are 12 Molina and Albir’s translation techniques used by the translator, with three dominant techniques as follows: established equivalent, reduction, and literal translation. The average accuracy of the translation of interrogative sentences is 2.69 that if reviewed based on the accuracy parameters by Nababan (2012), this score indicates that interrogative sentences in this study overall have been translated quite accuratel
ANALYSIS OF FLOUTING MAXIMS AND CONVERSATIONAL IMPLICATURE TRANSLATION STRATEGIES IN ONE PIECE (LIVE-ACTION SERIES 2023) SUBTITLE
No full textThis study examines the flouting of Cooperative Principle maxims in conversational implicature and Gottlieb’s translation strategies used in the subtitles of One Piece (Live-Action Series 2023). This study aims to identify which conversational maxims are flouted, Gottlieb’s translation strategies employed, and how these implicatures are translated into the target language. This study used a qualitative descriptive method with document analysis as the data collection technique. The results showed that all four conversational maxims were flouted, and some implicatures flouted multiple maxims simultaneously. Most implicatures were translated into the same implicature in the target text, while a small number were translated explicitly and have undergone explicitation. The most frequently used translation strategy was Paraphrase, followed by Condensation, Transfer, Dislocation, Decimation, Expansion, and Deletion. Most of the implicatures translated explicitly use the Paraphrase strategy to ensure that the utterances are clear and align with the conversation.

Case-Based Reasoning Diagnosis Penyakit Pada Tanaman Kelapa Sawit
No full textOil palm cultivation is one of the main agricultural commodities in Indonesia, as oil palm plants have a relatively high economic value. However, oil palm cultivation is vulnerable to disease attacks that can threaten productivity. The lack of knowledge among farmers in managing plantations and addressing these problems can exacerbate damage to plants due to disease attacks. To address this issue, this research will develop an application using a Case-Based Reasoning (CBR) approach to diagnose diseases in oil palm plants with the nearest neighbor calculation algorithm. CBR will solve new problems by reusing knowledge to solve old problems that are similar and already have solutions. The nearest neighbor algorithm is useful for calculating similarity between new cases and old cases. The data for the research involves 7 types of diseases, 20 symptoms, and 345 cases of disease attacks on oil palm plants. The application testing uses 25 test cases and 320 case bases. From the test results, the application shows an accuracy rate of 31.00, with the highest similarity value reaching 0.98. In this research, it can be seen that the generated similarity values are high but the accuracy value is low. This can be caused by several factors, such as the data of the cases, feature representation, and insufficient diagnosis, which result in high similarity values due to the assignment of values to attribute categories and attribute value proximity.Budidaya tanaman kelapa sawit adalah salah satu komoditas pertanian utama di Indonesia, hal tersebut terjadi karena tanaman kelapa sawit memiliki nilai jual ekonomi yang cukup tinggi.
