Abstract

Greenhouse adalah bangunan yang secara khusus dirancang untuk melindungi tanaman dari kondisi lingkungan eksternal yang tidak menguntungkan, serta mengatur lingkungan internal guna menciptakan kondisi ideal yang mendukung pertumbuhan tanaman secara optimal. Namun, sistem monitoring konvensional di Greenhouse mengalami masalah tingginya penggunaan kuota internet dan packet loss akibat ketergantungan pada WiFi access point (AP). Dalam penelitian ini, dikembangkan sebuah sistem monitoring tanaman di Greenhouse menggunakan arsitektur master-slave menggunakan protokol ESP-NOW untuk mengatasi masalah packet loss. Selain itu, algoritma change detection diterapkan pada node master guna mengurangi pengiriman data yang redundan serta memperkecil ukuran paket data yang dikirimkan. Hasil pengujian menunjukkan bahwa tingkat packet loss mencapai 1,43% dari total 222.793 pengiriman data selama tiga hari, yang termasuk dalam kategori "sangat bagus" menurut standar TIPHON. Algoritma change detection juga berhasil mengurangi estimasi penggunaan kuota internet bulanan hingga 82,4 MB. Sistem yang dikembangkan ini terbukti efektif dan efisien dalam memantau kondisi lingkungan tanaman dengan tingkat keandalan yang tinggi, sekaligus mampu menghemat penggunaan kuota internet.

Abstract

The bathroom is a basic necessity for personal hygiene, yet many still use conventional methods. This research aims to determine the delay between the sensor reaching the set temperature and the data being sent to the system, as well as the effect of the number of heaters on the duration of heating the bathwater temperature. The system is designed using an Arduino WiFi R4 microcontroller and a DS18B20 temperature sensor to measure the bathwater temperature. Temperature data is sent to the server via the HTTP protocol when the temperature reaches the threshold value of 37°C to 40°C. The research results show that the average delay between the DS18B20 temperature sensor reaching the recorded temperature and the time the data is received by the system varies depending on the number of heaters used. With 1 heater, the average delay is 1958.33 ms. This delay increases with the addition of heaters, becoming 2574.995 ms with 2 heaters, 2599.995 ms with 3 heaters, and 3766.665 ms with 4 heaters. Adding heaters speeds up the water heating process. With 1 heater, the longest duration reaches 10 minutes 1.58 seconds at a temperature of 40°C. This duration decreases to 6 minutes with 2 heaters, 5 minutes 17 seconds with 3 heaters, and 1 minute 45 seconds with 4 heaters. This system is capable of providing a response in reaching the target temperature as well as managing and delivering temperature information in real-time on an Internet of Things (IoT)-based website.

Abstract

Posyandu lansia is a government initiative designed to improve the well-being and health of older people. The program includes periodic evaluation of nutritional status, which includes measuring body weight, height and looking up the nutritional status of the elderly. The manual measurements often used in posyandu, while accurate, are often time-consuming and require high accuracy from health workers. To overcome these challenges, a nutritional status measurement device system called SIGIZI was developed. This system is connected to the measuring device using the HTTP protocol to allow direct data communication between the measuring device and the website in real-time. The system uses load cell sensors to measure weight and ultrasonic sensors for height. Data from the sensors is sent to the server in real-time via HTTP protocol, using stable connections from various providers. After the data is received, the system automatically calculates the Body Mass Index (BMI) by dividing body weight by the square of height, the results of this calculation are used to assess the nutritional status of the elderly. Analysis reveals that the BMI values obtained from SIGIZI and manual measurements differ by an average of 0.4 kg/m², with an error rate of 1.7% and an accuracy of 98.3%, indicating that SIGIZI's measurements are very close to those obtained manually. Furthermore, the HTTP protocol used for SIGIZI data transmission shows a stable connection with Axis (3.0 ms), Telkomsel (3.2 ms), and Tri (3.6 ms). Additionally, the average data transmission delay of 203 ms falls within the acceptable range according to the TIPHON standard, demonstrating that the system is reliable for efficient data transmission.

Abstract

Manual infusion fluid volume monitoring in hospitals has the risk of delays, which can endanger patients such as dehydration or electrolyte disturbances. This problem is caused by the limited time and labor of nurses in monitoring infusions in real-time. This research aims to develop an edge computing-based infusion fluid monitoring and alert system to monitor the volume and speed of infusion droplets in real-time through the website. This system uses NodeMCU ESP32 to collect data from load cell and photodiode sensors, which are then processed on the edge server and displayed on the website. Tests were conducted in three conditions, namely Line of Sight (LoS), Non-Line of Sight (NLoS), and without edge computing. The test results show that the LoS condition provides the best performance with an average delay of 113 ms, while the NLoS condition increases the delay to 146 ms. Without edge computing, the delay is higher than with the use of edge computing. Based on the test results, the use of edge computing in LoS conditions provides the best performance with the lowest delay, thus significantly improving the efficiency of infusion monitoring and reducing the risk of delayed infusion fluid replacement. The system has a measurement accuracy of 99.48% on the first infusion device, 99.58% on the second infusion device, and 99.57% on the third infusion device.

Abstract

The monitoring system for water level in peatland is crucial for detecting the potential for fires, especially during the dry season. This study develops a water level monitoring system using a water float level sensor capable of detecting changes in water level in real-time. Data from the sensor is transmitted via the LoRa SX1278 Ra-02 module, enabling long-range data transmission. The system was tested under two conditions: Line of Sight (LoS) and Non-Line of Sight (NLoS), to measure the signal strength indicated by the Received Signal Strength Indicator (RSSI). In the LoS condition, the best RSSI value was recorded at -63 dBm at a distance of 15.5 meters, while in the NLoS condition, the lowest RSSI value reached -110 dBm at a distance of 148 meters. The results show that this system is effective in monitoring water levels in peatland with reliable data transmission, even in remote areas. The integration of the water float level sensor and LoRa technology in this system has the potential to be a valuable tool for preventing peatland fires through real-time monitoring of water conditions.

Abstract

Education is a learning process aimed at enhancing students' abilities in the school environment. SMP Negeri 12 Sungai Ambawang is one of the educational institutions located in Sungai Ambawang District. In the learning process, each student has a different level of understanding of the material being taught. Some students struggle to grasp lessons at the same pace as their peers, which categorizes them as slow learners. Lack of awareness about slow learners can hinder the teaching and learning process, as teachers must repeatedly explain the material. Therefore, this study aims to identify and classify slow learners using the C4.5 machine learning algorithm to help schools design more effective and adaptive learning strategies. The classification of slow learners is divided into four categories: normal, mild, moderate, and severe. The dataset consists of 135 data points, including 81 training samples and 54 testing samples. The attributes used include scores from subjects such as Civics (PKN), Indonesian Language, Mathematics, Natural Sciences (IPA), Social Sciences (IPS), and English. The C4.5 algorithm generates a decision tree with Natural Sciences (IPA) as the root node attribute. Testing using the Confusion Matrix shows an accuracy of 91%, precision of 54%, recall of 68%, and an error rate of 9%. The classification results indicate that 9% of students fall into the normal category, 24% into the mild category, 62% into the moderate category, and 0% into the severe category. These results demonstrate that the C4.5 algorithm is effective in classifying slow learners.

Abstract

Divisi Al-Akram merupakan unit usaha yang bergerak dibidang penjualan Al-Qur’an dan speaker Qur’an dengan berbagai macam model. Saat ini Al-Akram menggunakan berbagai macam platform dalam proses penjualannya, namun pencatatan dan pengolahan data produk dan penjualan masih dilakukan secara manual dan data tiap platform terpisah sehingga untuk mengakses data tersebut harus membuka satu persatu halaman pencatatan. Dari pemasalahan tersebut maka dibangunlah sebuah sistem untuk mengintegrasikan data penjualan dari banyak platform menggunakan Extensible Markup Language (XML). XML digunakan sebagai format data yang umum dalam web service, yang memungkinkan aplikasi untuk berkomunikasi dan berbagi informasi melalui jaringan. Dengan XML semua data dari multiplatform di konversi menjadi format XML untuk selanjutnya disimpan ke dalam database. Pada proses integrasi data penjualan pengguna menggunakan data tanggal, nama pembeli, produk yang dibeli, jumlah pembelian dan harga dari masing-masing platform. Berdasarkan hasil pengujian maka terbangunlah sistem yang dapat menampilkan seluruh data penjualan dengan status sinkron dengan data yang ada pada sistem sesuai dengan sumber data diantaranya Ads : 141, Marketplace: 111, Facebook: 104, Instagram: 39, dan Youtube: 52. Sistem juga akan menampilkan seluruh data penjualan seperti detail data pembeli diseluruh platform, trend perbandingan penjualan tiap bulannya, dan grafik-grafik penjualan dari tiap platform.
