Abstract

Fast problem-solving is one of the main keys to a company's reputation. Currently, most of the company's business processes are accommodated by applications. Often, applications in companies experience problems due to internal and external factors. Users send a request to solve problems by submitting the problem to the helpdesk tool or application. The requests at the helpdesk tool or application do not go directly to the technician who has the authority to solve them but instead go to the operator first and then escalate to the technician to be resolved. This process affects the efficiency of problem-solving time. This study proposes the use of text classification with deep learning to complete operator work. The method proposed in this study is the BiLSTM method. The total data used in this research is 160,000 helpdesk request data by dividing the data by 128,000 resolved data as training data and 32,000 on-progress data as testing data or 80% training data and 20% testing data. The research was conducted using 13 labels for the technician assignment route process Performance measurement of this study using a confusion matrix which obtained an accuracy 91.18%, precision 95.05%, and recall 93.28%

Abstract

Nusantara, Indonesia's new capital, has a land area 256,142 ha and a marine area 68,189 ha. Transmigrant residents in the North Penajam Paser Regency region has increased as a result. The difficulty of finding a place of worship in the closest location because they are unfamiliar with their location or the nearby roadways. We can utilize data visualization to show the distribution of places of worship in order to solve this issue. Analysis was done on several types of houses of worship, including mosques, churches, and musholla. Python is the programming language, and the libraries used are NumPy, Pandas, Matplotlib, Seaborn, RegEx, and Folium. Muslims for the majority of places of worship in IKN Nusantara (91.26%), musholla making up 57.92% of the total and mosques making up 33.33% and 8.74% are owned by Christians. Sukaraja Village, Semoi Dua Village, Argo Mulyo Village, and Tengin Baru Village have the highest concentration. Keywords: Data Visualization, House of Worship, IKN Nusantara, Python

Abstract

Large data nowadays can be used for analysis; thus, it can obtain important/valuable knowledge in various domains. Text analysis can be carried out by utilizing text mining using computational methods so that knowledge extraction can be carried out on large text data, including processing related to unstructured text data, which is written in natural language. Classification in text mining is a type of work with the searching process for a set of models or functions that describe and differentiate text data classes with the aim that the model can be used to predict the class of an object (text data) whose class is unknown. Text mining was carried out in this research to analyze text data through the Text Classification System using a classification method, namely the XGBoost (eXtreme Gradient Boosting) Method. A text classification system was developed to classify text in the form of articles. The highest accuracy obtained from the test is 77%.

Abstract

This research aims to design and implement an IoT-based automated fish feeding and dosing system to improve the efficiency of the feeding process through automation. The components used include the ESP32 microcontroller, RTC sensor, ultrasonic sensor, voltage sensor, stepper motor, LCD, DC motor, and relay. The system performs dosing and feeding based on user-defined schedules. Based on the research results, the system successfully monitors and controls the dosing and feeding process of the fish automatically. However, the overall success rate of the system is only 70%, with an average error rate of 1.36% for the voltage sensor and 1.33% for the ultrasonic sensor. The battery experiences an average hourly decrease of 0.19V during system operation. The system faced challenges such as relying on Wi-Fi connection to connect to the Firebase server, insufficient battery capacity, and the unreliability of the stepper motor for dosing purposes.

Abstract

Parkage delivery services play a crucial role in facilitating the easy and prompt sending and receiving of goods to the public. The package delivery sector has witnessed significant growth of 33.62% since the outbreak of the Covid-19 pandemic. However, package receipt often presents challenges, including instances of damaged or lost packages. To address these issues, a system for package reception was designed and developed utilizing the Internet of Things (IoT) technology. The system operates by incorporating a UART GM66 Barcode Scanner, ESP-32CAM, Solenoid Door Lock, and Motor Stepper Nema 17. The primary objective of this research is to construct an automated package-reception system that can be controlled securely through a smartphone, thus ensuring protection against theft and package damage. System testing was performed on the functionality of the tool and communication with the telegram bot.

Abstract

Merdeka Belajar-Kampus Merdeka (MBKM) is a learning model in higher education that provides freedom and flexibility to students. This model aims to create a culture of creativity, innovation, and non-restriction by allowing students to study for three semesters outside their study programs. The program is an initiative of the Ministry of Education and Culture of the Republic of Indonesia in response to the impact of the Covid-19 pandemic. However, the MBKM program has received varied responses from the public, especially from students who have experienced its effects and hold different views on the MBKM policy. As this is a new policy, it is important to conduct analysis and evaluation of this program involving feedback from the community to enhance its performance. In a research on sentiment analysis of the Merdeka Belajar program on Twitter using the Naïve Bayes algorithm gets an accuracy value of 78% of the model to be able to predict positive, negative, and neutral classes from the 203 testing data used or 20% of all data (1015 data).

Abstract

Pratima is usually kept in temples or kept in sacred rooms. Lack of care and supervision causes easy cases of theft and damage due to fire. An Internet of Things-based pratima monitoring system is needed to avoid some of the threats that occur. Devices that are made connected to the internet for monitoring, and controlling monitoring devices so that Pratima remains safe. The Internet of Things-based pratima monitoring system is expected to be an early prevention system for acts of theft and damage due to fire. The results obtained are all the features successfully run. The measurement values of the ultrasonic sensor are 11CM and 16CM, while the ruler measurements are 10.5CM and 16CM. The temperature on the DHT22 is 70.50°C, and the flame sensor value is 123. The microwave sensor detects movement, and the image capture is stored on firebase and SD Card.

Abstract

Water in the reservoir on the first floor is often empty, resulting in no running water for each toilet in the Information Technology. In addition, the water pump in the Information Technology is still turned on manually, so the officer must occasionally control the water pump. Method Software Development Life Cycle (SDLC) Waterfall model to be used in this study. The hardware used is NodeMCU ESP8266, HCS-R04 which functions to measure water level and water volume, relay, and YF-B10 which functions to measure water discharge and volume. The results obtained were that the water level measured using the HCS-R04 was 11 cm high, while the water level was 10.7 cm measured using a meter. The water discharge obtained is 6 L/m. The water pump status feature, and the ON/OFF feature on the Android application are declared successful for turning on and turning off the water pump.
