Abstract

Penggunaan daya listrik untuk menunjang kegiatan sehari-hari menjadikan konsumsi listrik seakan bukan hal yang patut dicermati. Padahal, dengan banyaknya alat atau perangkat elektronik penunjang kegiatan sehari-hari yang menggunakan daya listrik menjadikan penggunaan daya listrik semakin tinggi. Energi merupakan suatu hal yang sangat penting dalam suatu kehidupan, terutama Energi Listrik. Listrik merupakan energi yang sangat dibutuhkan oleh manusia dalam era modern ini maka dengan adanya perkembangan teknologi yang semakin pesat hal ini juga berbanding lurus dengan kebutuhan listrik yang semakin besar. Minyak bumi sebagai hasil dari penghasil energi saat ini , maka cepat atau lambat minyak bumi akan habis. Untuk itu perlu upaya untuk menghemat penggunaan energi dari sumber daya alam yang tidak dapat diperbaharui, salah satunya adalah dengan berperilaku hemat energi sehari-hari atau rumah tangga. Walaupun terlihat sederhana, namun ternyata banyak konsumsi listrik yang tidak kita sadari turut berkontribusi dalam meningkatnya penggunaan daya listrik setiap hari. Untuk itu, ada baiknya kita lebih mencermati setiap penggunaan daya listrik khususnya di rumah agar tidak hanya menghindari

Abstract

Mother's Milk (ASI) is nutritious food for babies up to 6 months, but it is also recommended that breast milk be given to babies up to 2 years old. The benefits of breastfeeding include for antibodies in infants, avoiding allergic diseases, avoiding the risk of diseases of the respiratory tract, reducing diarrhea, reducing diabetes, and others. The problems that occur in Indonesia are several things, namely the limitations of exclusive breastfeeding due to the lack of knowledge of mothers about breast care and the lack of use of breast care in breast care for breastfeeding mothers. This can have a negative impact from not doing breast care or breast care which can have a negative impact, one of which is mastitis or tissue problems in the breast. One of the efforts to get sufficient milk production is that mothers must routinely carry out breast care, namely the use of a Breast Care tool design for the lactation process. Breast massage device or Breast Care for the lactation process can be used when mothers experience breastfeeding problems, with vibrations generated from servo motors and control motors on the device so that it can produce 3 types of vibrations that nursing mothers can use during breastfeeding.

Abstract

Mayangsari, Kalipancur Village, Ngaliyan District is an area with the potential to experience river water overflows during high rainfall. This condition causes the community to be at risk of being late in evacuating goods or saving themselves because a simple, independent, and easy-to-operate early warning system is not yet available. This community service activity aims to implement a river water level rise early detection tool based on a float switch as an early warning facility that suits the needs of the community. The implementation method includes three stages, namely 1) socialization regarding mitigation and flood risk reduction, 2) installation of an early detection tool that works mechanically using a float switch without requiring an internet network so that it is easy to operate and maintain, and 3) training on the operation and maintenance of the tool for neighborhood administrators and residents. Activity evaluation was carried out through tool function tests and observation of participants' abilities in operating and maintaining the installed system. The results of the activity show that the tool is able to activate the buzzer automatically when the water surface reaches a warning limit of about one meter according to the set settings. Based on the results of function tests on-site, the system can work according to the design and be utilized by residents as an early warning medium. In addition, the community has understood how to operate and maintain the tool so that the system can be used independently. The implementation of this tool provides an alternative early warning system that is simple, easy to maintain, and supports community preparedness in facing potential floods in the local environment.

Abstract

Medical waste presents a serious threat to health and the environment if not properly managed, especially in clinical facilities that require high hygiene standards. Manual waste disposal is still commonly practiced, which increases the risk of cross-contamination and reduces operational efficiency. This research aims to design and develop an automated and hygienic SmartBin system for medical waste using Artificial Intelligence (AI) and edge computing technologies without relying on internet connectivity. The system employs distance and weight sensors controlled by an Arduino Uno R3 microcontroller, along with a local image recognition module to classify medical waste based on type. All classification and system responses are processed locally to ensure fast and independent operation. A notification feature using visual and audio indicators is included to alert staff when the bin is full or when hazardous waste is detected. Testing conducted in a simulated clinical environment demonstrated a classification accuracy rate of 92% and reduced direct human contact by up to 85%. This study concludes that the SmartBin system, powered by AI and edge computing and supported by the Arduino Uno R3, offers an effective solution for improving hygiene and safety in medical waste management.
