Abstract

Internet of Things (IoT) technology can be applied in many ways, one of which is home automation or Smart Home. There are several sensors and actuator modules in the Smart Home system such as movement sensors (PIR) to detect the presence of living things around the house, radio wave frequency-based authentication sensors (RFID) to ensure that only registered residents can enter the house, actuator servo actuator (SG90) which is used to open the door, and actuator switch (Relay) to automatically turn off the lights. All activities at home that apply the Smart Home concept can be done automatically without touching it directly by using a special application called SUSAH v2, which is an Android-based application created using MIT App Inventor. What is still a concern is the lack of the Smart Home system where the network usInternet of Things (IoT) technology can be applied in many ways, one of which is home automation or Smart Home.

All activities at home that apply the Smart Home concept can be done automatically without touching it directly by using a special application called SUSAH v2, which is an Android-based application created using MIT App Inventor. What is still a concern is the lack of the Smart Home system where the network used is still a LAN and can only be controlled if the user is on the same network as the Smart Home system. Therefore, this research objective is to developing, testing, and implementing security using cryptographic methods and the integration of the Antares Platform based on the MQTT protocol to be able to make the Smart Home system accessible on a WAN anywhere and anytime, taking into account the security of the data information sent.

Abstract

This paper aims to apply the weight selection feature by considering the Gain Ratio value in the decision tree algorithm in classifying student academic scores. We determine the feature selection from the gain ratio based on the split value information to reduce the feature's (attribute) bias value. The highest Gain Ratio' value will be the root of the branching in the tree in which becomes a determining feature (attribute) of student graduation. We use 82 data which are divide into two classes called a pass and a not pass. From the data, we know that the attribute ip smt 7 got the highest gain ratio value with 0.581. On the other hand, the multimedia introduction attribute got the lowest gain ratio value with 0.070. The calculation model using cross-validation with a value of k = 5 resulted in optimal performance. The resulting accuracy is 79.19% and AUC 0.778 using the decision tree algorithm. The threshold value of the gain ratio used is 1.00 so that four attributes are not used in this paper. feature selection using weights with information gain ratio will select the attribute selection process to be built in the model.

Abstract

Stunting adalah masalah gizi buruk yang disebabkan oleh kekurangan asupan gizi yang terus menerus yang menyebabkan anak mengalami gangguan pertumbuhan, yaitu tinggi badan yang lebih rendah atau pendek (kerdil) dari standar usianya. Hipotiroidisme kongenital adalah penyakit yang disebabkan oleh kurangnya hormon tiroid di dalam rahim. Kekurangan hormon tiroid menyebabkan gangguan pada tumbuh kembang anak pada masa emasnya.  Untuk pencegahan stunting dan HK, saat ini Dinas Kesehatan (Dinkes) Depok menggunakan buku Kesehatan Ibu dan Anak (KIA) sebagai media edukasi. Berbekal adanya beberapa materi perkembangan balita yang dikemas dalam format e-book berupa buku KIA didistribusikan melalui posyandu dirasa kurang efektif dan kurang sesuai dengan karakter lingkungan saat ini.Tujuan kegiatan pengabdian masyarakat ini adalah pengembangan Aplikasi SakuBalita yang dikemas dalam format video motion grafis yang lebih menarik untuk disimak dan ditonton. Pengabdian masyarakat SakuBalita dikembangkan melalui 5 tahap, yaitu identifikasi permasalahan dengan mitra, pembuatan media edukasi motion grafis, pengujian aplikasi motion grafis, integrasi dengan Depok Single Window (DSW) dan sosialisasi kepada masyarakat. Pembuatan motionn grafis SakuBalita dikembangkan menggunakan software Adobe Illustrator dan Adobe After Effect, menghasilkan 12 video yang disesuaikan dengan usia perkembangan bayi.Aplikasi ini diharapkan dapat dimanfaatkan secara lebih luas oleh fasilitator dan masyarakat sebagai media edukasi pencegahan stunting dan HK.
