Abstract

Breast milk is the main source of nutrition for infants and is highly susceptible to spoilage if not stored at the right temperature. This system uses temperature sensors to monitor the thermal conditions in the storage cabin and automatically control the cooling fan to maintain the ideal temperature for breast milk storage. Test results show that the thermoelectric-based cooling system works optimally in conditions without products, with an initial temperature of 31.3°C that decreases to 2.3°C within 70 minutes. However, in conditions with breast milk products, the initial temperature of 35.3°C could only be reduced to 5.4°C within 120 minutes. This difference indicates that the presence of the product provides an additional thermal load that slows down the cooling process. Therefore, a responsive automatic temperature control system and better thermal insulation are needed to maintain the breast milk storage temperature stably around 4°C. This system is expected to maintain the quality of breast milk during storage and support users' needs in maintaining stable storage temperature efficiently.

Abstract

Alat peraga merupakan salah satu media pembelajaran yang dapat mempermudah guru dalam melaksanakan pengajaran dan memudahkan peserta didik memahami materi yang diberikan. Proses pembelajaran biologi yang dilaksanakan di SMP Yabri Terpadu Pekanbaru belum menggunakan alat peraga sebagai media pembelajaran. Kegiatan pengabdian masyarakat dilaksanakan di SMP Yabri terpadu pekanbaru dengan tujuan membantu siswa yang kesulitan dalam memahami dan mengerjakan soal-soal Sistem Peredaran Darah Manusia. Alat peraga diharapkan dapat membantu siswa dalam mengingat bagaimana proses sistem peredaran darah manusia. Siswa dapat dengan mudah mengingat proses sistem peredaran darah manusia menggunakan alat peraga yang seolah-olah nyata dari pada membaca buku teks yang berbentuk narasi. Dengan begitu diharapkan penggunaan alat peraga dapat membantu guru mengatasi kesulitan belajar Biologi terutama dalam materi Sistem Peredaran Darah Manusia.

Abstract

Physics is one of the subjects that is a scourge for students majoring in Natural Sciences at Yapin Kertasemaya High School. Based on the results of the team's interview with the physics teacher, it was found that the students were weak in electricity. In overcoming this problem, a teaching tool is made to learn basic electricity. From the results of community service activities, it can be seen that students are very enthusiastic and easily understand the material provided using teaching aids.

Abstract

Gabah yang terlambat dikeringkan akan berdampak buruk terhadap kualitas beras. Hal ini disebabkan gabah yang dipanen dengan kadar udara tinggi dan kondisi lembab mengalami respirasi yang cepat. Akibatnya gabah membusuk, berjamur, berkecambah atau mengalami reaksi pencoklatan enzimatis sehingga nasi berwarna kuning/kuning kecoklatan. Kandungan udara maksimum yang dimiliki oleh gabah kering adalah antara 12-14%. Oleh karena itu, dibutuhkan alat ukur kadar air gabah sehingga kekeringan gabah dapat dipantau.  Penelitian ini bertujuan untuk menganalisis perbedaan lebar penampang pada alat ukur tingkat kekeringan gabah menggunakan jembatan wheatstone berbasis Arduino Uno. Penelitian ini melibatkan perbandingan lebar penampang yang berbeda pada alat ukur yang sama, dengan menganalisis pengaruhnya terhadap akurasi pengukuran tingkat kekeringan gabah. Hasil analisis ini diharapkan dapat memberikan wawasan lebih lanjut tentang bagaimana lebar penampang mempengaruhi akurasi pengukuran dan membantu dalam pengembangan alat ukur yang lebih presisi untuk menilai tingkat kekeringan gabah. Lebar penampang yang diteliti yaitu ukuran 1,5cm, 2,5cm, 3cm, dan 4cm. Berdasarkan hasil perhitungan dan percobaan, penampang dengan lebar 4cm menunjukkan keakuratan yang sesuai. Penampang ini menghasilkan nilai error kadar air sebesar 0,3% hingga 0,6% dan rata-rata error tegangan antara 0,052 VAC hingga 0,694 VAC menggunakan resistor 2,2MΩ. Hasil ini menunjukkan bahwa alat ukur dengan penampang 4cm mampu memberikan hasil yang mendekati nilai yang sebenarnya. Oleh karena itu, penampang dengan lebar 4 cm dapat dianggap sebagai pilihan yang baik untuk pengembangan alat ukur tingkat kekeringan gabah menggunakan jembatan wheatstone berbasis arduino uno.

Abstract

Water is one of the basic needs that must be met by humans. To meet drinking needs in urban areas, the easiest and cheapest way for people is to buy refilled drinking water. However, the process of filling drinking water is still done manually by humans, so it is prone to errors. Therefore, in this study, the automation of gallon water filling will be carried out using Outseal PLC. Outseal PLC is used because of its relatively low price and greater reliability when compared to a microcontroller. In addition, the gallon filling status will also be displayed on the HMI display. In this study, a trial will be conducted on a drinking water installation at the Indramayu State Polytechnic (Polindra). Before testing, the flow sensor used must be calibrated first. Calibration is done by comparing the results of the flow sensor readings with the PDAM water meter to obtain a conversion of pulses to liters of water. Based on the tests that have been carried out, the results obtained are that the system can work well, namely the valve and pump turn on when the start button is pressed and will automatically turn off when the sensor has read a water volume of 19 liters. However, the sensor shows different readings when the water source used has a different water flow rate. In the first calibration using PDAM water flow rate, a pulse value of 464 was obtained for 1 liter of water, while in the second calibration using pump water flow rate, a pulse value of 566 was obtained for 1 liter of water. This is caused by the sensor used having less sensitivity to changes in water flow rate, which results in different reading results for different water flow rate. Therefore, the sensor must be recalibrated if it is to be used in water installations with different water flow rate. Although the sensor reading values are inconsistent, from tests carried out 40 times, the difference in readings is less than 10%.
