SIKEPUL: Sistem Informasi Untuk Administrasi Transaksi Jual Beli Pengepul Rongsokan Menggunakan Metode Waterfall

Currently collector businessmen are experiencing problems, namely the absence of data collection for suppliers and collapsed transaction activities. In addition, the administrative data collection process is still carried out manually by the admin, , one of which is using notes when making junk transactions and when partners make payments to collectors, there are often communication errors in junk transactions between suppliers and partners often occur. In order to overcome the existing problems, this research proposes the development of a collector administration information system named SIKEPUL using the laravel framework. The method in developing the system used is the waterfall method. The results showed that the SIKEPUL information system could solve the problems faced. The overall results of the questionnaire for 30 respondents were that 20% said it was very good, 52% said it was good, and 28% said it was enough for this system.

CLARITY AND PRONUNCIATION OF AB-INITIO AIR TRAFFIC CONTROLLER

The increasing number of aircraft flying around the world has led to the requirement for air traffic controllers to improve their communication skills to face high demand traffic in the future. The paper examines the communication errors in the pilot-controller communication of six ab-initio air traffic controllers during simulation training. More than three hours of conversation were collected and analyzed qualitatively using conversational analysis. The transcribed data yielded a total of 62 instances of communication errors. The data revealed that clarity and pronunciation of ab-initio controllers contributed to problematic communication and reduced the efficiency of the air traffic controllers in communicating. In contrast, pronunciation errors rarely diminished comprehension amongst the controllers and pilots who share a similar first language and are familiar with the use of English in a lingua franca setting. The study also describes other instances of communication errors in pilot-controller communication. The results indicate that ab-initio air traffic controllers need to be proficient in three main areas in pilot controller communication to improve their performance: aviation phraseology, aviation English, and aviation knowledge. The findings suggest that pilots and air traffic controllers should achieve level 4 (operational) in aviation language proficiency test, before proceeding to aviation training that requires them to be proficient in their language skills.

Software Design about Integrated Fault Diagnosis for the Propulsion System of the Tracked Amphibious Assault Vehicle

This paper describes the design of model-based fault diagnosis software to apply to the propulsion system in tracked amphibious assault vehicle which consists of an engine, a transmission, a cooling system, and two waterjets. This software includes specific functions to detect the failures regarding sensor malfunctions, mechanical malfunctions, control errors, and communication errors. This software generates the proper malfunction codes which are classified as the warning and caution. In order to validate the fault diagnosis software, the manual and automatic test are performed using the test program with 32 test cases. Test results show that the designed fault diagnosis software is reliable and effective for applying to the propulsion system.

Rancang Bangun Sistem Informasi Helpdesk Ticketing Berbasis Web pada PT. Mitra Tiga Berlian Bekasi

In company activities, the IT helpdesk plays an important role in ensuring and providing the best quality related to information technology. When carrying out work activities that use information technology, there are problems that arise in the use of IT, including at PT. Mitra Tiga Berlian (MTB). MTB is a company engaged in the service sector, to be precise a car service workshop (body repair and oven painting specialist) located on Jl. Kalimanggis, Jatikarya, Bekasi. In designing the IT helpdesk information system on MTB, the authors conducted observations and interviews beforehand designing a web-based information system using the waterfall method so that the system designed can be used by the IT department in problem reports quickly and can store information on the problem of each problem in the complaint. that occurs, thus minimizing communication errors in the IT Helpdesk.

MATHEMATICS COMMUNICATION MISTAKES IN SOLVING HOTS PROBLEMS

Student mistakes in communicating mathematical ideas are still widely practiced. Therefore, it is essential to analyze students' mathematical communication errors in solving mathematical problems so that learning planning can be better. This study aims to describe students' mathematics communication errors in solving the higher-order thinking skill's problems in linear algebra and matrix subject. The type of research is a qualitative descriptive study. They were 155 students as subject research. The data analysis started by collecting students' answers and then grouped them according to mathematics communication skills criteria. Later identified and analyzed the errors made by students of each mathematics communication criteria. The results showed that mathematical communication errors on the indicators of writing mathematical situations were concept errors and principle errors. The declaring idea's mathematical communication error is a concept error, a principle error, and an operation error. Furthermore, mathematical communication errors on the indicator state the results of solving-problem using the language itself is a concept error and operator error.

Automatic Communication Error Detection Using Speech Recognition and Linguistic Analysis for Proactive Control of Loss of Separation

Losses of separation (LoS) are breaches of regulations that specify the minimum distance between aircraft in controlled airspace. Erroneous communications between air traffic controllers (ATCs) and pilots are leading contributors to LoS that result in elevated risk of fatal accidents. An air traffic control system that could identify communication errors promptly would, therefore, be advantageous. Establishing such a system requires a systematic characterization of communication errors to reveal how various communication arrangements and errors influence the development of LoS. Such know-how could guide the ATCs and pilots in identifying the parts of their communication processes and content that most influence the occurrence of LoS. Existing studies of LoS focus on simulation of aircraft operation processes with little quantitative analysis about how communication issues arise and result in elevated risks of LoS. This paper presents a method for supporting automatic communication error detection through integrated use of speech recognition, text analysis, and formal modeling of airport operational processes. The proposed method focuses on: identifying communication features to guide the detection of vulnerable communications; characterizing communication errors; and Bayesian Network modeling for predicting communication errors and LoS using the features derived from ATC–pilot communications. Major findings show that incorrect read-backs by pilots are highly correlated with a majority of LoS. Results indicate the proposed method could form a basis for automating communication error detection and preventing LoS. The integrated Automatic Speech Recognition and Natural Language Processing functions may be incorporated into existing aviation applications for real-time ATC–pilot communication monitoring and preventive LoS control.

Social Media and Digital Information Sources in News Coverage of Crisis, Disaster, and Emergency Situations

Journalists play a key role in digital emergency situations. In the midst of the chaos generated by a pandemic like the COVID-19 crisis, the information transmitted by the journalist is crucial to save lives and minimize damage. This chapter explores journalists' reliance on and trust in official and unofficial digital information sources. Specifically, the authors explore the authorities' official information sources involved in crisis management and the unofficial information sources (i.e., victims and those affected). The research suggests a model for journalists' relationship with their digital information sources in covering crises by exploring dependence, type of contact, trust, and purpose. It also synthesizes the main communication errors of the public authorities that manage the response to the crisis.
