Abstract

Breast milk is nutrition for newborns, where exclusive breastfeeding will be given to babies until they are six months old. The hormone oxytocin can affect the production of breast milk. The release of the hormone oxytocin is carried out by a stimulation of the nipples through baby sucking or massage where breast massage is called breast message which can be done by a mother, or with the help of a special massage clinic to facilitate breastfeeding. The author created an Automatic Oxytocin Massage Vest to Accelerate Breast Milk Production in Breastfeeding Mothers. The strategy for implementing the vest tool can be used by the community, and knowing the level of usefulness of the tool. The next step will be knowing the effectiveness of the implementation of the vest using the "One Groups Pretest-Posttest Design" method, namely a research design that has a pretest before being given treatment and a posttest after being given treatment. Based on the results of the respondents and the analysis that has been carried out, it will be concluded that the hormone oxytocin is a hormone that has an important influence on the production of breast milk in nursing mothers, oxytocin massage tools are effective in increasing milk production in breastfeeding mothers, it is proven by 60% of the results of expressing breast milk from respondents more look at using an oxytocin massager. The reduced production after using the tool is influenced by several factors, including stress when using the tool and adding formula milk to babies during exclusive breastfeeding.

Abstract

Pencatatan presensi praktikum secara manual berisiko menimbulkan kesalahan, memperlambat rekapitulasi, dan menyulitkan pemantauan kehadiran secara real-time, sehingga diperlukan sistem presensi digital yang terintegrasi. Penelitian ini bertujuan merancang dan menguji sistem presensi praktikum berbasis sidik jari yang terhubung dengan website monitoring secara real-time. Metode penyelesaian masalah dilakukan melalui studi lapangan di Laboratorium Teknik Elektro, studi literatur, perancangan perangkat keras dan perangkat lunak, pengujian fungsional, serta evaluasi kinerja sistem. Sistem dibangun dari mikrokontroler ESP32 sebagai pengendali utama, sensor sidik jari AS608 untuk autentikasi biometrik, modul Real Time Clock (RTC) DS3231 sebagai penanda waktu, LCD I2C 16×2, LED, dan buzzer sebagai indikator, serta website berbasis Laravel (PHP) dan MySQL untuk penyimpanan dan penampilan data yang dikirim melalui jaringan Wi-Fi. Tahapan penelitian meliputi studi lapangan di Laboratorium Teknik Elektro, studi literatur, perencanaan dan perancangan alat, pengujian, serta evaluasi. Hasil pengujian menunjukkan bahwa seluruh percobaan identifikasi sidik jari berhasil (5 dari 5 percobaan) dengan waktu respons rata-rata 0,87 detik, pengiriman data ke website rata-rata 1,29 detik, dan waktu respons pada pengujian sistem keseluruhan berkisar 0,72–2,14 detik, sehingga memenuhi kriteria keberhasilan yang ditetapkan (akurasi ≥ 90% dan waktu pengiriman < 5 detik). Website mampu menampilkan data kehadiran, mengelola data mahasiswa, praktikum, dan nilai, serta mengekspor data ke Excel. Kebaruan penelitian ini terletak pada integrasi sidik jari berbasis ESP32 dan website monitoring presensi praktikum secara real-time, dengan kinerja yang dipengaruhi kondisi jari dan kualitas jaringan.
