Seiring dengan pertambahan penduduk dan pembangunan ekonomi, jenis dan kuantitas limbah cair semakin besar. Di lain pihak kebutuhan air bersih juga semakin meningkat. Hal ini tidak diimbangi dengan kondisi kualitas air yang semakin menurun. Salah satu syarat air yang dapat dimanfaatkan untuk kebutuhan air bersih adalah air yang memiliki nilai salinitas ≤0.5 ppt. Salinitas menggambarkan kadar garam yang terlarut dalam air. Pada penelitian ini dirancang pengukuran salinitas air tercemar limbah cair menggunakan sensor konduktivitas dan Arduino UNO sebagai sistem kontrol. Penelitian ini bertujuan untuk mengetahui apakah air sungai yang diuji layak dijadikan sumber air bersih berdasarkan parameter salinitas. Hasil karakterisasi sensor menunjukkan sensitivitas sensor sebesar 0.4152 mV/ppt dengan kesalahan relatif maksimum sebesar 5.26%. Pada pengujian salinitas air sungai, diambil sampel yang berasal dari wilayah Cipinang, Banjir Kanal Timur (BKT), Galur, dan Bekasi. Berdasarkan hasil pengujian salinitas, sampel air sungai yang diambil dari keempat wilayah yang berbeda memenuhi syarat salinitas air bersih yaitu ≤0.5 ppt sehingga layak dijadikan sumber air bersih.
The stunting prevalence in Indonesia is still above the WHO minimum standard of 20%. An important aspect of early detection of stunting is to monitor the nutritional status of children under five periodically. In daily practice, nutritional status is obtained through anthropometry. The main anthropometric parameters are body mass, height, and head circumference. This research entails the development of an integrated and non-contact anthropometric system for measuring body mass, height, and head circumference for children aged 12–60 months. This non-contact method can prevent the transmission of infectious diseases, especially during the COVID-19 pandemic. For the development of a prototype, three types of sensors are used: load, proximity, and temperature sensor. In addition, a load cell sensor is used to measure body mass, an infrared sensor to measure height and head circumference, ultrasonic sensor to measure height. In addition, the anthropometric system developed is equipped with an MLX90614-DCI sensor to measure temperature, a thermal printer to print measurement results, and sound output. The results of the tests showed that this anthropometric system had an average error less than 5%. Therefore, it is suitable to measure the body mass, height, and head circumference of children under five.
According to WHO, the incidence of hyperemesis gravidarum reaches 12.5% of all pregnancies in the world. Pregnancy check-up visits for pregnant women in Indonesia obtained data on mothers with hyperemesis gravidarum reaching 14.8% of all pregnancies. Nausea and vomiting occur in 60-80% of primigravida and 40-60% of multigravida. Management of nausea and vomiting can be done by non-pharmacological methods. Non-pharmacological therapies such as drinking boiled red ginger and coconut water. Red ginger contains zingiberol, zingiberena essential oil, curcumin, bisabilena, flandrena, gingerol, and vitamin A which can reduce nausea and vomiting. Coconut water also contains minerals, namely magnesium, potassium, and calcium. It turns out that drinking coconut water can relieve symptoms of nausea and vomiting. It is known that the comparison of giving coconut water with red ginger to pregnant women in the first trimester in reducing hyperemia gravidarum. Quasi experimental with a pretest protest design with a two experimental design. The samples in this study were all pregnant women in the first trimester at BPM Umiatin in January - February 2022 as many as 60 people, the sampling technique was total sampling. There is an effectiveness of giving coconut water and red ginger to pregnant women in the first trimester in reducing hyperemia gravidarum (p.value 0.000). After comparison between the groups of giving coconut water and red ginger decoction, it was concluded that both administrations were equally effective in reducing hyperemia gravidarum. Coconut water and red ginger decoction are both effective in reducing hyperemia gravidarum. Midwives are expected to provide counseling to pregnant women how to make red ginger stew and drink coconut water to reduce hyperemesis gravidarum. Keywords : Hyperemesis Gravidarum, Coconut Water, Red Ginger ABSTRAK Menurut WHO jumlah kejadian hiperemesis gravidarum mencapai 12,5% dari seluruh jumlah kehamilan di dunia. Kunjungan pemeriksaan kehamilan ibu hamil di Indonesia diperoleh data ibu dengan hiperemesis gravidarum mencapai 14,8% dari seluruh kehamilan. Mual dan muntah terjadi pada 60-80% primigravida dan 40-60% pada multigravida. Penatalaksanaan mual dan muntah dapat dilakukan dengan cara non farmakologi. Terapi nonfarmakologis seperti minum rebusan jahe merah dan air kelapa. Jahe merah mengandung zingiberol, minyak atsiri zingiberena, kurkumen, bisabilena, flandrena, gingerol, vitamin A yang bisa menurunkan mual muntah. Air kelapa juga memiliki kandungan mineral, yaitu magnesium, kalium, dan kalsium yang ternyata minum air kelapa dapat meredakan gejala mual muntah. Diketahui perbandingan pemberian air kelapa dengan jahe merah pada ibu hamil trimester I dalam menurunkan hiperemisis gravidarum. Quasi eksperimental dengan rancangan pretest protest with design two eksperiment. Sampel dalam penelitian ini adalah seluruh ibu hamil trimester I di BPM Umiatin pada bulan Januari - Februari 2022 sebanyak 60 orang, teknik pemgambilan sampel yaitu total sampling. Ada efektivitas pemberian air kelapa dan jahe merah pada ibu hamil trimester I dalam menurunkan hiperemisis gravidarum (p.value 0,000). Perbandingan sesudah antara kelompok pemberian air kelapa dan rebusan jahe merah disimpulkan bahwa dari kedua pemberian sama-sama efektif dalam menurunkan hiperemisis gravidarum. Air kelapa dan rebusan jahe merah sama-sama efektif dalam menurunkan hiperemisis gravidarum. Diharapkan Bidan memberikan konseling kepada ibu hamil cara membuat rebusan jahe merah dan minum air kelapa untuk mengurangi hiperemesis gravidarum.

AbstrakPulse Electromagnetic Therapy (PEMFt) atau lebih dikenal dengan PEMF merupakan salah satu modalitas yang disetujui oleh Food and Drug Administration (FDA) untuk membantu proses penyembuhan fraktur tulang non union (gagal sambung). Saat ini alat PEMF yang dijual dengan harga yang tidak murah, memiliki parameter fisis yang bervariasi sehingga dalam penggunaannya menghasilkan efektivitas beragam dan terkadang menimbulkan kontraindikasi. Dalam penelitian ini telah dilakukan desain, pembuatan dan uji coba prototipe alat PEMF menggunakan Arduino dan Labview. Tujuan dari penelitian ini adalah mendapatkan alat PEMF yang dapat digunakan dalam penelitian bioloektromagnetik. Penelitian dilakukan dalam tiga tahap yaitu tahap desain dan perancangan perangkat keras, desain dan perancangan perangkat lunak dan tahap ketiga adalah ujicoba alat PEMF untuk penelitian fraktur tulang menggunakan hewan coba tikus.

Obesity is a mojar public health problem in worldwide, especially in Indonesia. Obesity in addition to affecting productivity, is also trigger for other chronic disease such as diabetes and cardiac disease. Body mass index is an assessment tool used to assess degree of individual adiposity to define overweight, obesity, and severe obesity.The determination of obesity is based on the calculation of Body Mass Index (BMI), which devide body weight (kg) by height (cm2). In addition to the method of regulating diet, exercise, and bariatric surgery for weight loss, it was reported that the biophysical therapy tool, that is static magnetic field (SMF) became a modality for weight loss. Based on research reports, it proves that the static magnetic field affects weight loss in the group of obese mice after 30 days of exposure. Therefore, in this study, we carried out static magnetic field exposure to obese mice with a field intensity of 2 mT for 1 hour/day. Mice were exposed gradually to SMF on 2, 7, 14, and 21 days to determine the effectiveness of SMF to obesity in mice in terms of weight loss and cellular adipose cell density. The results showed that the weight of mice decreased significantly on 2nd and 7th days of exposure, the trend showed a decrease in body weight until the 14th day. The density of adipose tissue is increased after exposure to SMF on the 14th and 21st days of exposure. It showed that early exposure to SMF (2 and 7 days) could induce weight loss in mice, while cellularly SMF increased adipose cell density on late exposure (14 and 21 days).
