Abstract

Presto food is one of the favorite foods of Indonesians. Some of the favorite types of presto food are grilled chicken, presto duck, fish pepes, and presto milkfish. Sidoarjo Regency is one of the regions in East Java that has an area of 15,530 hectares of ponds that produce abundant milkfish of approximately 9,866,300 tons. This is a factor in the emergence of MSMEs engaged in the culinary sector, one of which is UKM Presto Sidoarjo. Limited production equipment causes the production process to be inefficient in terms of time and fuel. Marketing that has not been widespread and product packaging that is less attractive is a factor in the product being less known to the public. The implementation method is carried out through a participatory approach, training and mentoring, as well as discussion activities between the proposing team and partners. The result of this activity is the creation of an automatic presto machine that is able to increase production capacity from 5 kg per process to 10 kg per process and the formation of partners who are independent in using the machine and increasing sales turnover through marketing on social media and product packaging that has good, creative elements, imprints on consumers and labels.

Abstract

Antena array adalah antena yang terdiri dari lebih dari satu elemen, dalam upaya menerapkan modifikasi array penelitian ini menggunakan antena Vivaldi. Aplikasi antena vivaldi banyak digunakan dalam teknologi Ground Penetrating Radar, Medical Imaging seperti deteksi tumor otak dan kanker payudara. Penggabungan antena vivaldi dengan metode array memiliki kelebihan dapat menghasilkan gain yang lebih tinggi, dengan kelebihan gain yang lebih tinggi maka daya pancar antena penelitian ini bisa memfokuskan daya yang dipancarkan atau disebut pola radiasi. Desain antena yang dibuat ada tiga macam yaitu antena Coplanar Vivaldi elemen tunggal, antena Coplanar Vivaldi dengan 2 elemen dan 4 elemen array yang bekerja di frekuensi L, S dan C band. Dimensi substrat dari ketiga antena array vivaldi dibuat sama aitu 500 mm x 227 mm x 1.635 mm dan di desain untuk bekerja di frekuensi 1-8 GHz dengan menggunakan bahan copper pada pacth antena dengan tebal 0.035 mm, dan juga bahan FR-4 pada substrat dengan tebal 1.6 mm. Dengan dimensi ukuran substrat yang sama antena array dengan 4 elemen memiliki nilai Gain yang lebih tinggi dibandingkan dengan desain antena array 2 elemen dan 1 elemen. Dari hasil simulasi didapatkan untuk desain antena array 4 elemen memiliki Gain tertinggi 11.2 dB pada frekuensi 2 GHz dan 1 elemen memiliki Gain tertinggi 6.6. dB pada frekuensi 2 GHz. Dari hasil simulasi tersebut didapatkan bahwa untuk ukuran substrat yang sama, kinerja return loss terbaik diperoleh untuk elemen tunggal namun untk parameter Gain tertinggi diperoleh untuk antena 4 elemen array.

Abstract

The existence of substation operators is essential for monitoring substation equipment and operating control rooms. In addition, substation operators also have other tasks, such as inspecting substation equipment in the switchyard or in-service inspection (Level 1 inspection). This condition is less than ideal because the operator cannot monitor the control room continuously while in the switchyard. The control panel at the substation is equipped with an alarm annunciator, which is auxiliary equipment that serves to provide warning signs to the operator regarding which protection functions are working. Therefore, it is necessary to have a monitoring system that can provide real-time information about the condition of the control panel alarm annunciator. This research models a fault alarm monitoring system that can provide notification messages according to the type of fault automatically through the Telegram application. The system test results show the average value of 100 test data on the five types of fault, resulting in an accuracy rate of 100%, a precision rate of 100%, a recall rate of 100%, an error rate of 0%, and an F1-score rate of 100%. This is because all test data on the five types of fault were detected correctly, and no test data from other types of fault was detected as the five types of fault. Based on these averages, it can be concluded that using a confusion matrix to measure the performance of the fault alarm monitoring system on the IoT-based control panel annunciator alarm shows excellent system performance results.
