Abstract

An innovative technological development, the position tracking system uses latitude and longitude coordinates to determine the GPS's location. The covid-19 pandemic has caused the demand for cool box delivery for convalescent blood plasma to increase significantly. The obstacle in the field is the hospital's position and patient rooms far from the reach convalescent donors, so they require a cool box for delivery. The problem is tracking the cool box accurately and precisely so that it can be monitored by the hospital properly. For this reason, it is necessary to increase the accuracy of the GPS position in the cool box by using fuzzy logic algorithms The Ublox NEO-6M is one GPS module that can be utilized for navigation. This module uses UART connection using the NMEA 0183 protocol and has an accuracy level of around 2.5 meters to 10 meters. In this research, validation of the accuracy of the GPS coordinate position was carried out on a Blood Cool Box device which was designed using the fuzzy logic method. The Sugeno method fuzzy logic algorithm is used to validate the accuracy of GPS coordinate positions based on latitude and longitude obtained from the GPS sensor module. The test results show a Mean Absolute Percent Error (MAPE) value of 21.66% which can be concluded that the Sugeno fuzzy logic method algorithm has forecasting model capabilities that are suitable for use as a validation method for testing GPS position coordinates.

Abstract

Penelitian ini menerapkan teknologi web services dengan metode REST API pada Sistem Monitoring Manajemen Yayasan Badan Wakaf Sultan Agung untuk mengintegrasikan sistem yang berbeda platform dari unit yang berbeda sehingga kebutuhan informasi yang lengkap. Pengujian menunjukkan bahwa teknologi REST API berhasil merealisasikan interoperabilitas antara Sistem Monitoring Manajemen YBWSA dengan dua sistem lainnya yang berbeda platform. Pengujian REST API dilakukan dengan 2 cara yaitu dengan memasukan parameter sesuai dengan desain dari API Endpoint, dari pengujian tersebut REST API dapat mengembalikan data sesuai dengan parameter yang digunakan, kemudian jika data yang dicari maka akan mengembalikan HTTP Status Code ‘404’ (Not Found) dan jika parameter tidak sesuai maka REST API mengembalikan data dalam kondisi default atau tanpa parameter, dan pengujian kecepatan dari pengujian yang dilakukan terjadi perbedaan ketika menggunakan parameter dengan tidak menggunakan parameter misalkan pada API Endpoint /unissula/penelitian yang dilakukan sebanyak 10 kali yang masing-masing dalam satuan milisecond (ms). Untuk rata-rata kecepatan tanpa menggunakan parameter adalah 106, 2 milisecond, sedangkan dengan menggunakan parameter “judul=learning&kdProdi=55201” adalah 80 milisecond. Kecepatan request dari REST API dipengaruhi beberapa hal yaitu, penggunaan query, ukuran dari database, optimalisasi database seperti penggunaan query, index dalam tabel dan kecepatan jaringan internet.Kata Kunci : Interoperabilitas, REST API, Web Services

Abstract

Starting from the development of medical technology that is increasingly sophisticated and rapidly growing,researchers conduct medical research, namely about patient infusion handling services. In handling patient infusion, currently it is still manual which is carried out by nurses / medical personnel. Infusion handling services for patients still have shortcomings, namely the process of monitoring and replacing infusion fluids which are often late. If the problem is not treated quickly, it can lead to problems, namely the presence of air embolism in the blood vessels (the entry of foreign objects into the blood vessels, for example air). From that problem, the researchers made a new innovation in medical technology in handling infusions automatically and based on IoT. In this study, the smart online infusion device that has been made has good features and is very effective in handling infusions. This device has 3 main functions, namely: it can monitor the remaining infusion, it can change the infusion fluid automatically and it can indicate a blocked patient's infusion. This device already has a method for processing data with fuzzy logic. Media monitoring has been supported by a website that can be controlled remotely and in real time. Tests have been carried out and the effectiveness of the system is found to have an error rate of 0.2% - 0.7% and has an accuracy of 98%. Thus this tool can be used in terms of handling patient infusion automatically.

Abstract

The current condition, in Karimunjawa Island, is supplied by diesel power with a total power output of 400kW. The number of households in this island is 1545, while the number of electricity customers as many as 850 homes with the local electrification ratio of 55%. With such high load electrification, the generator is only operated from 05.00pm-06.00pm every day to limit the operating costs. Methodology used was the determination of the size of the PV generator capacity based on the percentage of daily generation. The selection of conversion technology with hybrid concept synergizes photovoltaic to be combined with diesel. Loading simulations are performed with HOMER application that provides a variety of features on a variety of configurations and scenarios designed.The first scenario is in the form of giving additional capacity by using the power of 100kW of PV system and at peak load by adding the duration of the day with 5 hours, it is obtained the production of PV of 800kWh/day with the selling price of $ 3,900;/kWh. The second scenario is in the form of giving additional capacity by using the power of 100kW of PV system at noon for 10 hours and during peak load, it gains total value production of PV with1400kWh/day and distributed to system with a selling price of Rp 3,867/kWh.

Abstract

The reflow soldering process is an important stage in the assembly of electronic components that requires high-precision temperature control to ensure the quality of the solder joints. This study aims to evaluate the performance of a K-type thermocouple temperature sensor integrated into the solder reflow control system. Evaluation was carried out through temperature measurements at 20 different points, ranging from 35°C to 220°C, with a focus on reading accuracy and error rate. The results of the experiment showed that the type K thermocouple sensor had an error range between 0.02°C to 0.97°C, with an average error value of 0.54°C.  These findings indicate that the sensor is stable and reliable enough to be used in industrial applications that demand temperature precision. The advantages of these sensors lie in their cost efficiency, ease of integration, and responsiveness to temperature changes. Nonetheless, periodic calibration is still necessary to maintain long-term accuracy, especially in dynamic work environments. This research contributes to the development of temperature control systems in the electronic manufacturing process, especially in the selection of the right sensors to support production quality. The conclusion of this study confirms that the K-type thermocouple is a practical and economical solution in reflow soldering systems, with sufficient performance to meet industry standards.

Abstract

Suhu berlebih pada kubikel 20 kV merupakan salah satu faktor utama penyebab kegagalan isolasi yang dapat memicu gangguan hubung singkat, kerusakan peralatan, dan penurunan keandalan sistem tenaga listrik. Pada sebagian besar gardu induk, pemantauan suhu masih dilakukan secara manual melalui inspeksi periodik sehingga tidak mampu mendeteksi lonjakan suhu secara cepat dan kontinu. Penelitian ini bertujuan merancang sistem peringatan dini berbasis Internet of Things (IoT) yang mampu memantau suhu kubikel 20 kV secara real-time dan mengirimkan notifikasi otomatis ketika terjadi anomali termal. Sistem menggunakan sensor termal radiometrik FLIR Lepton 3.5 yang terintegrasi dengan mikrokontroler ESP32-WROVER-E untuk membaca suhu pada terminasi kabel, terminal CT, dan konektor utama. Data dikirimkan secara nirkabel ke Google Spreadsheet sebagai basis penyimpanan dan ditampilkan dalam dashboard pemantauan. Power Automate Desktop digunakan untuk melakukan screen scraping, pengolahan data, penentuan ambang batas, serta pemicu pengiriman notifikasi ke WhatsApp melalui API Fonnte. Hasil pengujian lapangan menunjukkan sistem menunjukkan hasil uji pengukuran dengan selisih rata-rata sebesar 0,62°C terhadap alat ukur acuan yang telah terkalibrasi dan mampu mengirimkan notifikasi dalam waktu kurang dari          1 Menit. Sistem ini mampu meningkatkan akurasi deteksi dini hotspot, mendukung pelaksanaan Condition Based Maintenance, serta meningkatkan keandalan operasi kubikel di gardu induk. Kata Kunci: IoT, Early Warning System, Thermal Monitoring, FLIR Lepton, WhatsApp API.
