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.

This paper proposes a performance analysis of the auotscaling methods that can be utilized in Kubernetes Clusters in order to determine cost-efficiency for services. This paper aims to accommodate the specifications for an analysis by using Google Kubernetes Engine (GKE) built into Google Cloud Platform (GCP) as a platform to orchestrate clusters alongside deployed services. To fulfill the cluster model, customized cluster settings and NGINX-based services are developed to manage the website used for load testing in order to determine the behavior of the autoscaling methods. This paper proposes an experiment using real-time transmission of Virtual Users (VU) sent from an application, called k6, used to simulate a number of users accessing the website within a time frame through a public network. During the experiment, the quality of service of the website is measured and analyzed using metrics and events from GKE and the results made by k6 to determine whether the autoscaling system works within set parameters and determine cost efficiency in Kubernetes cluster. The proposed load test is able to ensure that the number of HTTP requests results in HTTP Status Code 200 and that 95% of the requests are completed in less than 2 seconds.

The Named Data Network (NDN) is a future network concept that addresses some of the issues present in the current internet architecture. One of the main advantages of NDN is the use of content caching at each router, enabling faster and more efficient data access. As internet network technology develops, the demand for video content continues to increase every year. Therefore, video optimization and delivery require high access speeds so that clients can run content from the server seamlessly. This research incorporates NDN-DPDK (Named Data Network-DData Plane Development Kit), which is designed as hardware acceleration, and uses NDN's default forwarder, Network Forwarding Daemon (NFD), which allows a wide variety of experiments with NDN architecture. The implementation and analysis of video streaming performance will use Quality of Service (QoS) parameters such as RTT, throughput, and startup delay to measure the quality of video streaming on the network side. In addition, CPU measurements are made on the router closest to the client to evaluate the traffic load required by the forwarder to transmit data. The results of implementation and analysis in this study obtained video streaming quality on the second accessor with an RTT time of 4 seconds, throughput above 0.4 MBps, a video startup delay of 8 seconds, and 100% CPU usage.

ABSTRAKPada makalah ini, kami membandingkan protokol routing proaktif Optimized Link State Routing (OLSR) dan protokol routing reaktif Ad-hoc on-demand distance vector (AODV) dan Dynamic Source Routing (DSR) pada model propagasi Shadowing dan pergerakan pada mobile adhoc network (MANET). Terdapat dua skenario pengujian, yaitu dampak dari kecepatan pergerakan pengguna dan variasi waktu jeda pengguna dengan mobilitas Random Way Point (RWP). Hasil simulasi menunjukkan bahwa semakin besar kecepatan maka kinerja throughput akan menurun, sedangkan delay dan Normalized Routing Load (NRL) akan meningkat. Semakin lama waktu jeda, semakin lama topologi berubah, akibatnya parameter throughput meningkat sedangkan delay end-to-end dan NRL menurun. OLSR proaktif menunjukkan kinerja terbaik dibandingkan dengan protokol lain berdasarkan parameter throughput, sedangkan AODV reaktif mengungguli penundaan end-to-end dan parameter NRL.Kata kunci: Protokol perutean, shadowing, Mobility, MANETÂ ABSTRACTIn this paper, we compared the proactive routing protocols Optimized Link State Routing (OLSR) and the reactive routing protocols Ad-hoc on-demand distance vector (AODV) and Dynamic Source Routing (DSR) in shadowing propagation and mobility model on mobile adhoc network (MANET). There are two test scenarios, such as the impact of user movement velocity and variations in user pause time with Random Way Point (RWP) mobility. In user velocity testing, the greater the speed, the throughput performance will decrease, while the delay and Normalized Routing Load (NRL) will increase. The pause time test describes the dynamics of changing network topology. The longer the pause time, the longer the topology changes, as a result, the throughput parameter increases while the end-to-end delay and NRL decrease. The proactive OLSR shows the best performance compared to other protocols based on throughput parameters, while the reactive AODV outperforms for end-to-end delay and NRL parameters.Keywords: routing protocol, shadowing, Mobility, MANET

The Sindulang Village community faces obstacles in internet access due to uneven network infrastructure. This challenge makes it difficult for residents to obtain the latest information which is a key factor in supporting economic progress, education, and community welfare in the area. These obstacles arise due to geographical conditions that are difficult to access and suboptimal regional structures, which cause significant obstacles in resource management and accessibility. The Telkom University, PT. Tigaresi Bangun Nusaperdana, and SMK Al Amah Sindulang community service teams together overcome these obstacles by building Sindulang NetConnect as a public Wifi station as an innovative answer to provide easy internet access while accelerating the digitalization process for the Sindulang Village Community. In addition, in order to develop the Teaching Factory (TeFa) at SMK Al Amah Sindulang, an office container was implemented as a means of producing a Wifi network that can be used by students to improve their skills and experience in the networking field. This implementation was carried out in 2 stages, where the first stage was the construction of an office container and public Wifi services and in the second year a digital community space would be developed. Based on the results of the questionnaire on 30 respondents, it showed that 93.3% strongly agreed with the implementation of office containers as public Wifi stations and TeFa facilities that provide benefits for the Sindulang Village Community and students of SMK AL Amah Sindulang.

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.
