Abstract

Perkembangan teknologi dan telekomunikasi berbasis Internet of Things (IoT) telah membantu pekerjaan manusia terutama dalam berhubungan, berkomunikasi, pengiriman, dan pemrosesan data. Salah satu pemanfaatan penggunaan sistem teknologi dan telekomunikasi berbasis Internet of Things (IoT) adalah pada pengolahan makanan fermentasi tape ketan. Tape ketan adalah makanan fermentasi dari beras ketan yang menggunakan ragi untuk proses fermentasinya. Pada penelitian sebelumnya proses fermentasi dengan objek ketan belum adanya pengembangan teknologi dan telekomunikasi alat berbasis Internet of Things. Hal ini mengakibatkan sulit memantau proses fermentasi apabila jauh dari alat. Oleh sebab itu, penulis bertujuan untuk membuat sebuah penelitian penerapan Internet of Things (IoT) untuk melakukan proses monitoring fermentasi tape ketan. Dengan NodeMCU ESP8266 bertindak sebagai microcontroller dan koneksi internet dari sistem, sensor DHT22 sebagai sensor untuk membaca suhu pada ruang penyimpanan, Relay 2 Channel bertindak sebagai saklar on dan off pada lampu dan kipas, kemudian sensor MQ3 merupakan sensor yang berfungsi untuk membaca kadar alkohol pada tape ketan, dimana hasil pembacaan sensor DHT22 dan MQ3 yang akan ditampilkan di LCD 16x2 yang terintegrasi dengan modul 12C. Kemudian data sensor dan visualisasi juga akan ditampilkan pada aplikasi Blynk yang terdapat pada smartphone. Dengan hasil penelitian proses fermentasi dengan menggunakan alat dapat bekerja dengan baik dan mampu melakukan proses fermentasi lebih cepat 15 jam dibanding proses fermentasi secara tradisional dengan menggunakan aplikasi Blynk sebagai media Internet of Things (IoT) yang membantu memantau proses fermentasi di dekat maupun di luar area jangkauan alat.

Abstract

The advancement of technology demands an acceleration in data transmission, where the utilization of UWB MIMO presents a solution to address this issue. However, the implementation of MIMO techniques involving multiple transmitters and receivers leads to an increase in mutual coupling values. This results in a decline in antenna performance. Therefore, a decoupling structure on the ground is employed to minimize mutual coupling values and enhance isolation. The progress of technology calls for expedited data transmission, where the utilization of UWB MIMO presents a solution to address this issue. However, the use of MIMO techniques with numerous transmitters and receivers escalates mutual coupling values. This subsequently leads to a degradation in antenna performance. Hence, a decoupling structure on the ground is employed to minimize mutual coupling values as much as possible and enhance isolation. In this research, a UWB MIMO antenna was designed utilizing a 30 × 40 mm FR-4 Epoxy substrate with a thickness of 0,8 mm and a dielectric constant of 4,4. The antenna was designed using CST Studio 2019 software, followed by fabrication, and subsequently, a comparison was drawn between the simulation and fabrication results.The obtained results have fulfilled the UWB antenna specifications within the frequency range of 3,07 GHz to 11 GHz, with simulated mutual coupling values lower than -15 dB and an envelope correlation coefficient (ECC) value less than 0,01. The resulting radiation pattern is omnidirectional. During the measurements, mutual coupling values of less than -15 dB and good isolation is found within the frequency range of 4,3 GHz to 11 GHz

Abstract

Chili plants are one of the horticultural crops in Indonesia which have great potential in the Indonesian economy. However, crop failure often occurs. One of the main factors causing this is pest and disease attacks on chili plants. This requires early prevention which can reduce losses. With today's technological developments, prevention can be done easily and economically by using deep learning methods. YOLO is a deep learning algorithm that is commonly used to detect objects in real time. There are 4 classes that will be tested, namely leaves affected by yellow virus disease, leaf spot, thrips pests, and healthy chili leaves. Testing was carried out with a web-based application created with the flask framework. The accuracy results of the YOLO model training process with epoch 150 were 73%. The precision, recall and mAP values ​​obtained were 77.4%, 67.1% and 75.1%. Testing produces accuracy above 74%. The results of this research still produce accuracy that is not high enough, but the application can be used to detect it well and is quite accurate.

Abstract

In Indonesia, which has a tropical climate there is a lot of wood which is very suitable for mushroom growth. However, some of these mushrooms are poisonous and should be avoided. By examining the morphological characteristics of the mushroom, such as the shape of the mushroom cap, color, smell, and other characteristics it is possible to identify between poisonous and non-poisonous mushrooms. However, some poisonous mushrooms have the same morphological characteristics as non-poisonous mushrooms, making it difficult for us to differentiate them when seen with the naked eye. As a solution to this problem, machine learning is needed to identify which mushrooms are poisonous and which are not. As in this research, Convolutional Neural Network (CNN) and You Only Look Once (YOLO) were used as methods for identification. The stages in this research include collecting datasets, modeling and training data, and the final process, namely deployment. CNN Method got an accuracy value of 55% and succeeded in identifying 5 correct and 5 incorrect images from the 10 images given. Meanwhile, using YOLOv5, we got a high accuracy value of 91% and succeeded in identifying 9 correct and 1 incorrect image out of the 10 images provided. From a comparison of the 2 methods, it was found that detecting poisonous and non-toxic mushrooms was better using the YOLO method than the CNN method

Abstract

Information technology has now become a primary need for many individuals, facilitating access to various needs, including work, learning, and other activities. Mobile phones allow users to stay connected to the internet without interruption, even when traveling out of town, thanks to their ability to switch between cells or through a process known as handover. The focus of this article is on the impact of handover on 4G LTE networks. The data collection approach in this research uses the drive test method by utilizing the tems pocket application to retrieve internet network data. The research results highlight the importance of understanding how handover can affect 4G LTE network performance. With the role of information technology increasingly dominating everyday life, a deep understanding of technical aspects such as handover has become essential to maintaining the quality and efficient availability of cellular communications services.

Abstract

This research discusses the design, implementation, and evaluation of Fiber to the Home (FTTH) networks using Gigabit Passive Optical Network (GPON) technology, including network topology design, device installation, activation, and quality of service analysis. Attenuation measurements were conducted before and after activation to ensure compliance with ITU-T G.984 standards, while Quality of Service (QoS) analysis using Wireshark application evaluated parameters such as throughput, packet loss, delay, and jitter. Results show an increase in network efficiency after activation, with a decrease in attenuation. QoS measurements showed excellent network performance, with high throughput (2,595 Kbps), no packet loss, low delay (3.106 ms), and minimal jitter (3.128 ms). This study provides a comprehensive overview of FTTH network implementation and the importance of quality of service evaluation to ensure optimal performance for end users. The systematic approach used can be a valuable guide for telecom operators and internet service providers in implementing reliable and efficient FTTH networks. The study also emphasizes the importance of continuous monitoring and evaluation of network performance, contributing to the technical understanding of FTTH implementation and highlighting the implications for end-user experience as well as the potential for future broadband service development.
