Abstract Restrictions on activities outside the home were imposed during the Covid-19 pandemic to minimize the spread of the Covid-19 virus. One of the activities outside the home that is often carried out is taking medication at a health facility. Children are an age group that is vulnerable to disease exposure. Many diseases that often occur in children, including diarrhea. One of the places prone to disease transmission is in health facilities, while children with diarrhea tend to be taken by their parents to health facilities. Therefore, there is a need for socialization about the handling of diarrhea in the pre-hospital phase or at home, so that children can be treated at home first if the conditions allow. The purpose of this study was to determine the effect of the Mother's Smart Card, which is a simplification of the MTBS book, on knowledge in managing diarrhea in children in the pre-hospital phase. This study used a quasi-experimental design with a pre and post test approach with purposive sampling technique on 30 mothers. Maternal knowledge is measured from knowledge of diarrhea and its management. The results of data analysis using the paired t-test showed that there was a significant effect of the Mother's Smart Card on the mother's knowledge in managing children's diarrhea at home with a value of p = 0.000. This means that the Mother's Smart Card can increase maternal knowledge in the management of pre-hospital phase children's diarrhea. This result is expected that the Mother's Smart Card can be a reference in increasing maternal knowledge, and minimizing treatment in inappropriate health facilities that can be at risk of Covid-19 transmission.

ABSTRAK Kasus kegawatan medis dapat terjadi dimana dan kapan saja, salah satunya adalah henti jantung dan demam anak. Akan sangat berbahaya kejadian yang terjadi di lingkungan masyarakat yang tidak ada orang yang mampu memberikan pertolongan pertama, ataupun tidak tahu kemana akan mencari pertolongan. Kesalahan memberikan pertolongan bisa membuat pasien menjadi lebih menderita dan meninggalkan kecacatan. Keadaan diatas memerlukan pertolongan yang baik dan segera sebelum pasien dibawa ke rumah sakit untuk perawatan definitif. Permasalahan muncul karena tidak banyak orang awam di yang bisa memberikan pertolongan pertama pada kejadian tersebut dan ketidaktahuan akan sistem pengaduan kasus tersebut. Kegiatan ini dilaksanakan dengan metode demonstrasi dan praktik agar partisipan memiliki pengetahuan dan keterampilan pertolongan pada henti jantung dan demam pada anak. Selain itu butuh pembuatan sebuah sistem sederhana berbasis komunitas sebagai alur awal pertolongan pasien, dengan sistem ini masyarakat mengetahui kemana mereka harus melapor. Semua rangkaian kegiatan tersebut dengan tujuan membentuk sebuah komunitas yang aman yang disebut “Safe Community”. Dari pelaksanaan kedua pelatihan tersebut di atas, terdapat peningkatan pengetahuan dan keterampilan masyarakat dalam memberikan pertolongan henti jantung dan demam anak yaitu sebesar rata-rata 23 poin dalam skala 100. Kata Kunci: Henti Jantung, Kejang Demam, Safe Community  ABSTRACT Medical emergency cases can occur anywhere and anytime, one of which is cardiac arrest and childhood fever. It would be very dangerous to happen in a community where no one is able to provide first aid, or does not know where to go for help. Mistakes in providing help can make patients suffer more and leave disabilities. The above conditions require good and immediate assistance before the patient is admitted to the hospital for definitive treatment. The problem arose because there were not many ordinary people who could provide first aid to the incident and they were ignorant of the complaint system for the case. This activity is carried out with demonstration and practical methods so that participants have the knowledge and skills to help with cardiac arrest and fever in children. In addition, it is necessary to create a simple community-based system as the initial flow of patient assistance, with this system the community knows where they have to report. All of these series of activities are aimed at forming a safe community called "Safe Community". From the implementation of the two pieces of training above, there is an increase in the knowledge and skills of the community in providing assistance for cardiac arrest and child fever, which is an average of 23 points on a scale of 100. Keywords: Cardiac Arrest, Febrile Convulsion, Safe Community
