Design of IoT-based System for Smart Temporary Waste Shelter

Internet of Things (IoT) is a concept where all products can interact with each other to help human activities by utilizing the internet. The IoT system can help solve problems such as the schedule-based retrieval system at a temporary shelter in Indonesia. This paper creates a web-based geographic information system along with the IoT-based waste temporary shelter prototype. The prototype also integrated with an Arduino Microcontroller so that it can sort the waste automatically into three types of waste, then record data in the form of height and weight, and send the results of the data to the database so that the geographic information system can display the results of the data. Node-RED serves as an Application Programming Interface (API) that sends data from the server to the database belonging to a web-based geographic information system. The results of the performance analysis are that the prototype has sorted waste well, and the system also produced good QoS by ETSI standards when looking at the network traffic from the MQTT server to the database, and from the end-user to the web. As for the QoE results for tools and systems have produced good results according to the ITU-T standard

Effect Of Price Sensitivity And Green Knowledge On The Interest In Buying Organik Vegetables In Bengkulu Province

Organic agricultural products in the current era are very attractive to farmers and consumers because there is no use of synthetic chemicals that can pose a danger to the health of the human body and the environment. Awareness of a healthy lifestyle makes the demand for organicproducts increasing for most consumers. Prices that are too high will make consumers switch to other similar products but with lower price offers make consumers doubt the quality of the product, thereby reducing buying interest in the product. . Green knowledge is defined as the knowledge that an individual has about knowing an issue or phenomenon that has a significant impact on the decision-making process. The purpose of this study was to determine the effect of price sensitivity and Green knowledge on the interest of organik sayuaran buyers in Bengkulu Province. This study was an associative study, using a sample of 100 respondents. Testing the research hypothesis using multiple regression, previously the data obtained must pass the validity and reability test. The results of the study stated that the variables of price sensitivity and green knowledge partially had an influence on the interest in buying organic vegetables in Bengkulu Province. Meanwhile, price and green knowledge together affect consumers' buying interest in organic vegetables. The value of the research determinant coefficient is 0.345, which means that the independent variable used only affects 34.5% of the variables tied to buying interest, while the remaining 65.5% is influenced by other variables outside the study

Advanced detection Denial of Service attack in the Internet of Things network based on MQTT protocol using fuzzy logic

Message Queuing Telemetry Transport (MQTT) is one of the popular protocols used on the Internet of Things (IoT) networks because of its lightweight nature. With the increasing number of devices connected to the internet, the number of cybercrimes on IoT networks will increase. One of the most popular attacks is the Denial of Service (DoS) attack. Standard security on MQTT uses SSL/TLS, but SSL/TLS is computationally wasteful for low-powered devices. The use of fuzzy logic algorithms with the Intrusion Detection System (IDS) scheme is suitable for detecting DoS because of its simple nature. This paper uses a fuzzy logic algorithm embedded in a node to detect DoS in the MQTT protocol with feature selection nodes. This paper's contribution is that the nodes feature selection used will monitor SUBSCRIBE and SUBACK traffic and provide this information to fuzzy input nodes to detect DoS attacks. Fuzzy performance evaluation is measured against changes in the number of nodes and attack intervals. The results obtained are that the more the number of nodes and the higher the traffic intensity, the fuzzy performance will decrease, and vice versa. However, the number of nodes and traffic intensity will affect fuzzy performance

Analisis Perbandingan Kinerja Sensor Jarak HC-SR04 dan GP2Y0A21YK Dengan Menggunakan Thingspeak dan Wireshark

Until now, Internet of Things (IoT) is a very interesting topic to research. This is due to the wide role that IoT can play in human life. This study aims to compare the performance of two sensors in an IoT-based distance detection system with the focus of the parameters being tested: sensor readings, Qos of data transmission, and power requirements. The two sensors that are the subject of comparison are HC-SR04 and GP2YA21YK. As an analytical tool, this research uses two tools, namely Thingspeak and Wireshak. The performance test results show that in terms of accuracy in determining distance, the HC-SR04 has a much better performance than the GP2YA21YK. On HC SR04, the average reading error is 0.82 cm, while on GP2YA21YK it is 14.40 cm. Meanwhile, in terms of QoS parameters, the two sensor systems show almost commensurate performance, the packet loss is both 0%, the throughput value is 37.01 kbps on HC-SR04 and 38.12 kbps on GP2YA21YK. As for the delay, the HC-SR04 sensor gives a value of 33.55 ms, and on GP2YA21YK it is 26.1 ms. Furthermore, based on power requirements, sensor systems using the HC-SR04 consume 14.36% less power than the system that use GP2YA21YK. By referring to the results of measurements and visualizations using Wireshark and Thingspeak, it can be concluded that the distance detection system using the HC-SR04 sensor is better than the system with the GP2YA21YK

Implementation of QR Code Attendance Security System Using RSA and Hash Algorithms

The quick response (QR) code-based attendance application contributes to reducing paper usage and attendance input errors. However, in its implementation process, the QR-code-based attendance at a Bandung school demonstrates weaknesses. Absent students can fake their attendance for themselves or friends. This type of attack is known as fake QR code generation. This research proposes a security authentication system using the Rivest–Shamir–Adleman (RSA) encryption algorithm and the secure hash algorithm 1 (SHA-1) to secure QR code-based attendance applications from fake QR code generation attacks. The RSA algorithm encrypts QR code data to maintain privacy, while the SHA-1 algorithm ensures data integrity. Based on this method, the mutual authentication process between the QR code data generated by the student and the attendance reading application by the teacher can be established. The results obtained from a series of tests showed that the security system in the student attendance recording application that had been implemented at Madrasah Aliyah (MA) Al-Mukhlishin could detect and prevent fake QR code generation attacks. The test was conducted by changing the impact of the key length on RSA-1024 bits and RSA-2048 bits. The results showed that in RSA-1024 bits, energy consumption of 0.14 J and time of 1.66 s is more efficient than that in RSA-2048 bits, with energy consumption of 0.19 J and time of 2.09 s. Interestingly, if a higher level of security is required, the key length should be increased at the expense of some energy and time efficiency
