    Queue System Analysis Using Arrival Patterns and Customer Service Patterns for Fast Food Restaurants at Simpang Dago Bandung

    Authors: Faysal Rafly, Muhammad Rafi Hafizh, Agung Rahmat Fardan, Suryatno Wiganepdo Soegoto, Rudhi Lesmana

    Abstract

    Queues are one of the problems that have a large enough influence for a fast-food restaurant, especially in the world of food and beverage. Queues occur because the high arrival rate is not matched by the maximum level of service. This study aims to determine the queuing model that occurs at the McDonald’s cashier and find out whether the queue model applied is efficient by comparing the results of observations and simulation results. The research method used is descriptive analysis with a quantitative approach to customers at McDonald’s restaurants with arrival times and service times every 20 minutes on both servers. The results showed that there are several things that affect the queuing system, namely arrival time, service time, number of servers and McDonald’s consumer eating hours. From this, we can simulate the addition of servers to reduce queues during peak hours, namely at lunch time. Of course, the optimal performance of the queuing system will provide satisfaction for consumers or buyers because it can reduce waiting time during the purchasing process. © School of Engineering, Taylor’s University.

    Authors: Muhamad Afghany Haryatno, Yeffry Handoko Putra

    Abstract

    The amount of information that people generate on daily life have put their smart devices as active participants of the business that runs by numerous organizations. However, following the process the information brought numerous people to consider the safety level, as some personal information might be leaked during the process. In the last few years, there have been a lot of national and international regulations that oblige organizations to follow certain rules in their information security program. This is mainly because leakage of personal information might put the victim’s privacy in danger, resulting in identity theft and perhaps financial loss. For organizations this situation could led them loss trust, reputation, and loyalty from their customers. Therefore, ensuring privacy during the process, storing, and sharing of personal information is important. Although it’s clear that security and privacy are two different terms, upon implementation security often believed covers privacy too. This paper seeks to enhance information system security, by developing privacy program using privacy by design as method. The goal is to illustrate and present some insight of how privacy by design address privacy in information system security. © School of Engineering, Taylor’s University.

  • Development of a Machine Learning Model for Multiple Membership Publication Documents

    Development of a Machine Learning Model for Multiple Membership Publication Documents

    authors: Apriani P. Purfini, Stephanie B. R Hersianie, Rio Yunanto

    Abstract

    This research aims to develop a learning model in the text mining process by modifying TFIDF. The methodology employed in this study consists of a literature review, data collection, data preprocessing, and document processing. Text mining is conducted using the title and keyword attributes in publication documents. The outcome of this research is a learning model with modified TFIDF to determine multiple memberships in publication documents. The modification of TFIDF weighting can group words according to their document field categories. In contrast, previous TFIDF methods could only group words per document, making it difficult to determine the field categories of publication documents. The results of this research are expected to provide a solution to achieve more accurate outcomes with the same data scheme. The modification of TFIDF weighting can group words according to their document field categories. These field categories consist of a collection of words from many documents that have characteristics in specific field categories. Longer documents tend to have higher TFIDF weights because they can contain more words. This condition can affect the comparison between long and short documents. TFIDF also does not consider the context surrounding words, so in some cases, context is crucial for understanding the meaning of words or phrases. © School of Engineering, Taylor’s University.

    Server Security and Air Quality Monitoring System Using Raspberry Pi 4 and Telegram

    Authors: Mochamad Fajar Wicaksono, Myrna Dwi Rahmatya

    Abstract

    The purpose of this research is to develop a system that uses Raspberry Pi and IoT technologies to monitor server room conditions such as temperature, humidity, air quality, and access rights security. The contribution of this research is that it makes it easier for users to monitor the server room and take appropriate action when something goes wrong. The method utilized in this study is experimental. The output obtained is in the form of a web display and telegram notifications. The brain of this system is the Raspberry Pi 4. The input received is temperature, humidity, carbon monoxide levels, carbon dioxide, and dust particle values. The thing that causes the Raspberry Pi 4 to activate the buzzer and send notifications via Telegram is when the temperature value is more than 230C, the humidity is less than 45% or 60%, the measured carbon monoxide value is more than 50 ppm, or carbon dioxide is more than 800 ppm or the AQI value of dust particles is more than 100. Regarding access rights, users can only enter the server room using a registered RFID card. Access rights violations will be detected by PIR1, PIR2, and Ultrasonic sensors. If this happens, the Raspberry Pi will take a photo with the Pi Camera, activate the buzzer, and send it via Telegram. The entire system testing process is tested into two main parts: temperature, humidity, AQI testing, and security testing related to access rights according to the program scenario and initial objectives. Test results show that every part is functioning 100%. The overall test shows 100% success where the system can do actions according to program conditions and scenarios. © School of Engineering, Taylor’s University.

    Authors: Diana Effendi, Rani Puspita Dhaniawaty, Mia Fitriawati, Delviola Cancerina, Aldi Ramadhan

    Abstract

    This research is the development of SIKEMAS (Mosque Financial Flow Information System), which is now referred to as the Qurban Service Information System (SIQUR), conducted at DKM Khairul Amal, Bandung City. There are problems in processing qurban data, at the Khairul Amal mosque DKM, which currently still uses conventional manual methods, which cause many problems starting from the qurban preparation stage, registration of qurban (shohibul qurban) and sacrificial animals, to the distribution of qurban meat. Another problem is the unsynchronized data between the availability of qurban meat and the number of recipients. Because it creates an application or system that has already been developed, this research was carried out utilizing the research and development technique. At the same time, the design of information systems uses object-oriented design tools using the Unified Modelling Language (UML). At the same time, the application is built with Java Netbeans 7.0 programming with MySql database. The result of measuring the respondents’ satisfaction index with SIQUR is 98%, which means that users are satisfied with the facilities in SIQUR. © 2024 Taylor’s University. All rights reserved.

    Authors: Hidayat H, Muhammad Salman Al-Farisi

    Abstract

    Obesity has become a significant global health issue, affecting populations in both developed and developing countries. The World Health Organization (WHO) reported a substantial rise in obesity rates since 1990, with 43% of individuals classified as overweight in 2022. This study aimed to design and implement an Android-based diet and jogging recommendation application targeting adults. Following the Waterfall model, the research adhered to a structured, sequential process that included requirements analysis, system design, implementation, testing, deployment, and maintenance phases. The application calculates Body Mass Index (BMI) based on user input, such as weight, height, age, and gender, categorizing individuals into seven classifications: Underweight, Normal weight, Pre-obesity, Obesity class I, II, and III. Personalized diet and exercise recommendations are then provided to help users achieve and sustain a healthy weight. The app integrates the Google Maps API to track jogging routes and the Low Carb Recipes API to offer calorie-based meal suggestions. Additionally, the Jogging Tracking feature allows users to monitor their jogging history. The results demonstrate that the application effectively delivers customized dietary and physical activity recommendations, aiding users in managing their caloric intake and maintaining consistent exercise routines. The system proves to be both functional and practical, offering a valuable tool in the fight against obesity, particularly in Indonesia. This research contributes to addressing the global obesity crisis by providing an accessible, technology-driven solution. © School of Engineering, Taylor’s University.

  • Utilization of Ferrocement and Zinc Plate as Floor Plate Formwork of Multi-Storey Houses

    Utilization of Ferrocement and Zinc Plate as Floor Plate Formwork of Multi-Storey Houses

    Authors: Y. Djoko Setiyarto, Vanya Jasmine Shaf

    Abstract

    Ferrocement is a thin-walled concrete that is less commonly used than reinforced concrete. On the other hand, zinc plate is a type of metal frequently utilized as roofing material and for rain gutters. This study aimed to evaluate the tensile strength of zinc and the flexural strength of ferrocement to ensure their safe load-bearing capacity for multi-storey building floors. The study was conducted experimentally by testing the strength of formwork plates made from ferrocement, with a base plate comprising a layer of zinc. The ferrocement used in the experiment contained two layers of wire mesh and mortar with a cement-to-sand ratio of 1:3. The experimental results yielded a formwork flexural strength value of 0.403 kNm, mortar compressive strength of 22.3 MPa and zinc yield stress of 194.6 MPa. Based on construction trial activities in multi-storey houses, zinc-coated ferrocement plates are deemed safe for application as permanent formwork for floor slabs. © 2025 Taylor’s University.
