Abstract

Stress is a condition of tension that affects emotions, thought processes, and the physical or psychological state of humans due to pressure from within or from outside a person, which can interfere with activities that can cause various diseases. Therefore, a tool is made to detect stress levels so that a person can monitor their condition and prevent stress from getting more severe and detrimental to the health of the body and mind. The stress level detection tool is designed using a galvanic skin response (GSR) sensor to detect skin response through a person's sweat glands and a heart rate sensor to detect heart rate. Furthermore, the reading results will be processed by microcontroller and then the stress level decision will be made using the fuzzy logic method and will be classified into Relax, Anxiety, Calm, and Stress. Based on the test results, the GSR parameter has the highest accuracy of 99.78%, and the heart rate parameter has the highest accuracy of 99.63%.

Abstract

This study explores the application of deep reinforcement learning (DRL) to solve the control problem of a single swing-up inverted pendulum. The primary focus is on investigating the impact of discount factor parameterization within the DRL framework. Specifically, the Deep Deterministic Policy Gradient (DDPG) algorithm is employed due to its effectiveness in handling continuous action spaces. A range of discount factor values is tested to evaluate their influence on training performance and stability. The results indicate that a discount factor of 0.99 yields the best overall performance, enabling the DDPG agent to successfully learn a stable swing-up strategy and maximize cumulative rewards. These findings highlight the critical role of the discount factor in DRL-based control systems and offer insights for optimizing learning performance in similar nonlinear control problems.

Abstract

To optimize land and yards as well as to produce healthy plants and minimal pest disturbances can be done with hydroponic farming techniques. Hydroponic plants such as vegetables have high nutrition and are healthy because they are free from the use of pesticides. In addition, hydroponics can also beautify the yard or yard of the house. For this reason, in this community service, counseling will be carried out on how to grow crops using hydroponics. With this activity, it is hoped that Women Farmers Group (KWT) at Jaten, Sendang Rejo will be more productive and can make the best use of the land by farming. It can also save expenses on kitchen ingredients, such as vegetables, spices, etc. The hydroponic stages are carried out in several stages, namely: sowing seeds (water spinach and mustard), carrying out hydroponic workshops, and implementing hydroponic practices. Hydroponic activities have been carried out well, so that further plant care is necessary until the plants can be harvested.

Abstract

The majority of Indonesia's population is Muslim, including more than 13,000 people with hearing impairments. In carrying out congregational prayers, the Deaf find it difficult to follow the instructions of the Imam's movement. The presence of hearing aids cannot be used by all persons with hearing impairments, and hearing aids often cause a buzzing sound, thus disturbing concentration. Therefore, in this study, a gyroscope bracelet will be made to assist people with hearing impairments in following the instructions of the Imam's movement when carrying out congregational prayers. The bracelet worn by the Imam will send a code in the form of a change in angle to the bracelet used by the Deaf congregation. The Z angle is a vertical angle in the gyroscope where the Z angle has an angular velocity of 360 degrees per second. The control system uses Arduino nano FT232RL FTDI FT232. The communication module uses HC-12 SI4463, with a wireless frequency of 433.4 - 473.0 MHz. The sensor for detecting changes in motion is the MPU6050 gyroscope sensor, the vibration indicator uses a micro vibrator motor. The bracelet used by the deaf will read the code from the Imam's device, with a notification in the form of a different vibration on every change in prayer movement. After experimenting with 30 people, the percentage of success was 84% ​​for all prayer positions. Thus, the gyroscope bracelet tool for prayer guides for the Deaf can help the Deaf community in carrying out congregational prayers.

Abstract

Sistem informasi akuntansi (SIA) saat ini digunakan oleh berbagai jenis lembaga untuk mengelola data dan informasi yang terkait dengan sistem akuntansi pada bisnis yang dijalankan oleh lembaga tersebut. Tujuan yang ingin dicapai adalah memudahkan proses analisis akuntansi untuk sistem pengendalian keuangan, strategi bisnis dan penerbitan pelaporan keuangan. Pengabdian ini mengambil studi kasus pengelolaan data perguliran pinjaman pada lembaga keuangan yang bergerak dalam penyediaan pinjaman modal wirausaha kepada masyarakat. Metode yang dilaksanakan yaitu  melakukan analisis dokumen, wawancara kepada pengelola organisasi dan pengamatan proses bisnis, baru dilanjutkan pembuatan aplikasi SIA. Hasil pengabdian merupakan penerapan teknologi informasi dalam bidang akuntansi dengan model client-server untuk efisiensi sumberdaya organisasi.

Abstract

Pada saat ini, semakin banyak variasi kuliner  (makanan), sehingga menyebabkan berbagai macam penyakit maupun gejala penyakit jika kita mengkonsumsinya terlalu berlebihan. Dengan adanya masalah ini, maka akan banyak orang yang berobat ke rumah sakit. Pada masa ini, selain rumah sakit juga berkembang Puskesmas maupun klinik kecil baik ditingkat Desa, Kelurahan maupun Kecamatan. Klinik pun terbagi atas berbagai macam yaitu klinik umum dan klinik gigi. Klinik maupun Puskesmas menyediakan peralatan medis untuk membantu menyembuhkan pasien atau untuk tindakan medis. Pengabdian ini bertujuan untuk memperbaiki maupun memberikan rekomendasi apakah alat medis pada klinik tersebut masih layak untuk diganti atau masih baik. Beberapa contoh alat medis yaitu tensimeter, thermometer , timbangan bayi, stetoskop dan timbangan orang dewasa. Tensimeter terdiri atas beberapa jenis yaitu tensimeter jarum, tensimeter air raksa dan sekarang telah berkembang tensimeter digital. Pengabdian yang dilakukan pada klinik ini yaitu mengidentifikasi peralatan tensimeter dan thermometer yang masih ada, jika terdapat kerusakan maka akan dilakukan perbaikan. Hasil dari pengabdian ini ditemukan kerusakan pada tiga tensimeter air raksa. Kesimpulan yang dapat diperoleh dari pengabdian ini adalah dengan adanya program pengabdian ini maka kita dapat membantu klinik tersebut.

Abstract

Generally, schools in remote areas, in this case SD Muhammadiyah Maesan and SD Muhammadiyah Bangeran have few students, this could be due to several factors related to learning technology, namely: teacher competence in using ICT devices for learning is inadequate, elementary schools do not yet have software as a forum for digital learning content that can be a medium for interaction of teaching and learning activities between teachers and students via the internet, ICT infrastructure in elementary schools is not sufficient for learning. Therefore, the community service team implemented a Moodle learning management system (LMS) platform for learning in both schools. With this e learning platform, it can make it easier for teachers or teaching staff to create IT / e learning-based teaching material content. The teachers are taught the process of installing, dressing and maintaining the devices. After the implementation of community service, SD Muhammadiyah Maesan and SD Muhammadiyah Bangeran can use e-learning / moodle cloud in managing the subjects to be taught.

Abstract

One of the impacts of the Covid-19 pandemic on the economic sector is the cessation of production activities in various businesses, falling levels of consumption and consumer confidence in a product. Rosalia is one of the small and medium business units engaged in the food sector, in the form of processed Salak products. The pandemic situation has also resulted in MSMEs being devoid of buyers, resulting in decreased income from business owners. Therefore, a marketing strategy is needed that can help this business to survive. One of the marketing techniques that will be applied is the use of social media and the creation of online shop accounts in marketplaces such as Shopee and business Instagram accounts. In addition, to ensure that the financial recording system in MSMEs is neatly organized, training on financial management will be given
