Abstract

Muscles are an important organ in the movement of the body's skeleton to carry out sports activities. Measurement of muscle activity during the exercise process can be done using electromyography (EMG). This research uses Myoware muscle sensor (AT-04-001) which is integrated with Arduino Uno and Xbee to monitor biceps brachii muscle fatigue wirelessly. Fatigue data processing is carried out objectively using the envelope and sliding window method and subjectively verbally from the respondents. From this study, it was found that muscle fatigue can be measured using the method objectively when there is an increase in EMG amplitude with a window size of 5 s. The indication of biceps brachii muscle fatigue for the right arm is stronger to withstand the load during exercise with the average duration of the measurement of the right arm is 41.87 s from 69.67 s; 53.53 s from 98.90 s and 76.87 s from 98.80 s with the ratio of the left arm tending to fatigue more quickly is 23.53 s from 42.13 s; 41.87 s from 51.60 s and 23.53 s from 44.73 s.

Abstract

The oscillation of frequency can cause the generator to run out of sync in a power system. Therefore, load frequency control (LFC) is needed to reduce frequency oscillation and prevent out of sync operation. The LFC regulates the governor to balance the turbine speed with changes in the load of existing. In this paper, a proportional integral differential (PID) controller and a battery energy storage system (BESS) are added to an LFC to improve the frequency stability of a power system. The parameters of the PID controller and BESS are optimized using the Bat algorithm (BA) to attain a good coordination. The frequency performance analysis is done by introducing disturbance in the form of changes in load power. The simulation results show that the frequency deviation of the system with the PID controller and BESS, has a faster settling time and smaller overshoot value. The system performs better than those with only the PID controller or the BESS. In conclusion, the BA algorithm can be used to find optimal parameter values of the PID controller and BESS for a synchronized coordination of an LFC.

Abstract

Kabupaten Banyuwangi masih menjadi produsen buah naga terbesar di Indonesia, dengan hasil panen pada tahun 2020 mencapai 82.544 ton yang meningkat dibandingkan tahun sebelumnya. Sekitar 80% pasokan buah naga di Indonesia berasal dari Banyuwangi. Desa Sukorejo, Kecamatan Bangorejo, Kabupaten Banyuwangi merupakan salah satu penghasil buah naga terbesar dengan lahan seluas 273 Ha digunakan untuk budidaya buah naga. Dalam budidayanya, inovasi terus dilakukan untuk meningkatkan hasil produksi. Salah satunya penggunaan lampu neon berwarna kuning yang dinyalakan pada malam hari untuk mempercepat dan memperbesar panen. Jumlah lampu neon yang banyak akan mengonsumsi listrik yang besar juga. Selaras dengan hal tersebut, dibutuhkan biaya yang besar juga. Oleh karena itu, diadakan Abmas dengan menerapkan teknologi berupa panel surya yang terintegrasi battery storage guna menunjang penerangan lampu pada lahan pertanian buah naga. Dengan adanya alat tersebut, penggunaan listrik dari PLN akan berkurang karena sebagian telah disediakan oleh panel surya dan battery storage. Abmas dibagi menjadi 4 tahap, yaitu tahap persiapan yang berkaitan dengan peninjauan lokasi secara langsung untuk memeriksa kembali permasalahan dan solusi terkait, tahap penyuluhan yang memberi penyuluhan kepada masyarakat Desa Sukorejo terkait sistem yang digunakan, tahap pengadaan yang meliputi pengadaan alat-alat serta penunjang, dan tahap instalasi perakitan PLTS yang terintegrasi dengan battery storage. Kegiatan ini memiliki kegunaan dalam meningkatkan efisiensi pertanian buah naga di Desa Sukorejo, Kecamatan Bangorejo, Kabupaten Banyuwangi yakni dengan membantu dengan mengurangi biaya operasional melalui penggunaan sumber daya energi baru terbarukan yang ramah lingkungan. Sekaligus menjadi model pertama pemanfaatan sumber daya energi baru terbarukan, mengingat besarnya potensi ini di Desa Sukorejo.
