Abstract

Along with the development of the times the need for electrical energy is increasing. PT. PLN (Persero) as a company that supplies electrical energy must be able to meet the needs of electrical energy to run a business to supply electric power in an even amount to meet the needs of the household, industrial, social and business sectors.. The purpose of this research to determine how much the growth of electrical loads in 2020 to 2025 at PT. PLN (Persero) Rayon Juwana. To find out the amount of increase in electrical energy required. Electrical data used data for 8 years, from 2012 to 2019. The results of this study are in the form of an estimate of the use and need for load electrical energy load for the next 5 years, from 2020 to 2025, the data used are the number of subscribers, connected power, and the amount of energy using a simulated neural network with the method (radial basis function). the results of this study an increase per year an average of 1% per year. in 2019 the value is 1.07%, in 2020 it is 1.10%, 2021 is 1.21%, for 2022 it is 1.27%, 2023 is 1.28%, 2024 is 1.17% and 2025 is 1.31 %.

Abstract

Gout is the final metabolite of purines. Purines are part of the nucleic acids found in the nuclei of body cells. Increased gout can cause rheumatic pain in the joint area and is often associated with extreme pain for those exposed to the disease. Doctors need to monitor so that they can assist patients in monitoring and treatment. Gout detection devices are only available in hospitals, clinics, health centers, laboratories, and equipment that was previously portable but could not be controlled directly by a doctor. The purpose of this study is to help make it easier for doctors to monitor patients with gout remotely or telemedicine via the internet. The research method uses blood to determine gout levels using the Internet of Things. Data acquisition is carried out with a resistance sensor (Authocheck) which is processed by the Arduino microcontroller. The processed data is then sent to the ESP8266 web server via WiFi. The use of the Internet of Things as a data transmission method for online use does not require human-to-human interaction. The sensor resistance value in the analog range obtained is 441.03 to 782.32 with a sensor voltage of 1.91 to 3.82 volts. The measured gout level is between 4 mg/dL and 8 mg/dL. The percentage of measured data with an average accuracy of 95.74% and an average error rate of 4.26% for the seven test data. Data is displayed directly on the device's LCD screen and on a web server that sends data from the ESP8266. Keywords: gout, Internet of Things, resistance sensor (Autocheck), telemedicine, web server ABSTRAKAsam urat merupakan metabolit akhir dari purin. Purin adalah bagian dari asam nukleat yang ditemukan dalam inti sel tubuh. Asam urat yang meningkat dapat menyebabkan nyeri rematik di area persendian dan sering dikaitkan dengan rasa sakit yang luar biasa bagi yang terpapar penyakit. Dokter perlu memantau agar dapat membantu pasien dalam pemantauan dan pengobatan. Alat pendeteksi asam urat hanya terdapat di rumah sakit, klinik, puskesmas, laboratorium dan alat-alat yang sebelumnya portable namun tidak dapat dikontrol langsung oleh dokter. Tujuan dari penelitian ini membantu memudahkan dokter untuk memantau pasien dengan penyakit asam urat secara jarak jauh atau telemedicine melalui internet. Metode penelitian menggunakan darah untuk menentukan kadar asam urat menggunakan Internet of Things. Akuisisi data dilakukan dengan sensor resistansi (Authocheck) yang diproses oleh mikrokontroler Arduino. Data yang telah diproses kemudian dikirim ke web server ESP8266 melalui  WiFi. Penggunaan Internet of Things sebagai metode transmisi data untuk penggunaan secara online tidak memerlukan interaksi manusia ke  manusia. Nilai  resistansi sensor pada rentang analog yang diperoleh adalah 441,03 hingga 782,32 dengan tegangan sensor 1,91 hingga 3,82 volt. Kadar asam urat yang diukur adalah antara 4 mg/dL dan 8 mg/dL. Persentase data terukur dengan akurasi rata-rata 95,74% dan rata-rata tingkat kesalahan  4,26% untuk tujuh data uji. Data ditampilkan langsung di layar LCD perangkat dan di web server yang mengirimkan data dari ESP8266.

Abstract

AbstrakKegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan keahlian siswa SMA Negeri 4 Semarang dalam perancangan desain Printed Circuit Board (PCB) untuk modul Internet of Things (IoT). Kegiatan dilaksanakan melalui pelatihan intensif yang dipadukan dengan praktik langsung, sehingga siswa memperoleh pemahaman mengenai dasar-dasar desain PCB, pengenalan perangkat lunak desain PCB, serta tahapan penyusunan skematik dan layout PCB. Program ini tidak hanya berorientasi pada peningkatan keterampilan teknis, tetapi juga bertujuan untuk menumbuhkan minat dan motivasi siswa dalam mengeksplorasi pemanfaatan teknologi IoT, khususnya pada sektor pertanian. Hasil kegiatan menunjukkan adanya peningkatan kompetensi yang signifikan, di mana kemampuan peserta meningkat dari tingkat pemahaman awal berupa pengenalan konsep dan komponen PCB menjadi mampu merancang dan mengimplementasikan modul IoT sederhana berbasis PCB. Peningkatan kompetensi tersebut ditunjukkan oleh hasil evaluasi kemampuan peserta pada skala penilaian 1–4, yang mengalami kenaikan dari rata-rata skor awal 1,2 menjadi 3,2 setelah kegiatan pelatihan. Selain itu, kegiatan ini memberikan dampak positif dalam mempersiapkan siswa menghadapi tantangan perkembangan teknologi di era Industri 4.0. Kata kunci: mikrokontroler; printed circuit board; internet of things. Abstract This community service activity aims to improve the skills of students at SMA Negeri 4 Semarang in designing Printed Circuit Boards (PCBs) for Internet of Things (IoT) modules. The activity was conducted through intensive training combined with hands-on practice, enabling students to gain an understanding of the fundamentals of PCB design, the introduction of PCB design software, and the stages of schematic and PCB layout development. The program was not only oriented toward enhancing technical skills but also aimed to foster students’ interest and motivation in exploring the application of IoT technology, particularly in the agricultural sector. The results of the activity indicate a significant improvement in participants’ competencies, where their abilities progressed from an initial level of understanding limited to basic concepts and PCB components to the capability of independently designing and implementing simple PCB-based IoT modules. This improvement is reflected in the evaluation results using a 1–4 competency assessment scale, which showed an increase in the average score from 1.2 before the training to 3.2 after the training. Furthermore, this activity had a positive impact on preparing students to face technological challenges in the era of Industry 4.0. Keywords: microcontroller; printed circuit board; internet of things
