Informasi curah hujan bulanan sangat diperlukan dalam perencanaan irigasi dan bangunan air, perencanaan infrastruktur, pertanian, transportasi dan juga telekomunikasi. Dengan adanya perbedaan sifat curah hujan bulanan setiap tahunnya, kita tidak dapat memprediksi sifat curah hujan yang akan terjadi pada tahun berikutnya. Backpropagation adalah salah satu metode dalam Jaringan Syaraf Tiruan (JST) yang digunakan untuk prediksi. Jaringan syaraf tiruan (JST) merupakan salah satu sistem pemrosesan informasi yang meniru cara kerja otak manusia. JST mempunyai kemampuan untuk memberikan keputusan terhadap data yang telah dipelajari sebelumnya. Pada penelitian ini, JST Backpropagation menggunakan 3 neuron berupa variabel input yaitu data curah hujan bulanan 3 tahun sebelumnya dengan target curah hujan bulanan tahun berikutnya, 1 lapisan tersembunyi dengan 3 neuron, Pada pengujia ini ditentukan nilai parameter learning rate (α) dimulai dari 0.01, 0.03, 0.05, 0.09 dan 0.1, sedangkan batasan epoch yang digunakan dimulai epoch 1000, epoch 1500 dan epoch 2000, dan nilai ambang batas (threshold) 0.0001, 0.00001 dan 0.000001, dalam proses pembelajaran dilakukan 5 kali pengujian terhadap data curah hujan bulanan. Akurasi MSE tekecil yang didapat pada pengujian paramater ini yaitu 0,005 terdapat pada learning rate 0,1 dengan epoch ke 2000, dari semua pengujian parameter yang dilakukan memiliki hasil prediksi yang sama yaitu dari 12 bulan terdapat 9 bulan yang sesuai dengan target dan 3 bulan yang tidak sesuai target terhadap data curah hujan bulanan tahun 2017. Sehingga kelayakan sistem yang didapatkan dari pengujian tersebut adalah 91,67%.

Jurusan Teknik Elektro Universitas Mataram menerapkan kurikulum yang mewajibkan mahasiswa memilih bidang keahlian setelah semester empat berdasarkan Indeks Prestasi Kumulatif (IPK). Hal ini membuat mahasiswa yang memiliki nilai rendah akan sulit untuk mendapatkan bidang keahlian penjurusan yang memiliki peminatan paling banyak dan tidak memiliki rekomendasi lain dari hasil pembagian bidang keahlian tersebut. Oleh karena itu, penelitian ini bertujuan untuk menerapkan sistem pengambilan keputusan untuk setiap peminatan bidang keahlian. Parameter yang digunakan sebagai data masukan dalam penentuan bidang keahlian adalah nilai mata kuliah dasar, IPK, minat mahasiswa, keinginan orang tua, dan keterampilan mahasiswa dalam menentukan peminatan bidang keahlian sebagai pengembangan dari sistem sebelumnya. Metode yang digunakan untuk mengola data masukan adalah logika Fuzzy Inferense System (FIS) dengan pendekatan fuzzy Mamdani bertingkat yang terdiri dari tahapan: fuzzifikasi, implikasi, komposisi aturan, dan defuzzifikasi. Jumlah sampel data yang digunakan sebanyak 65 data mahasiswa dari empat bidang keahlian. Hasil pengujian menunjukkan bahwa tingkat akurasi dari perbandingan antara hasil penentuan bidang keahlian dari sistem fuzzy Mamdani dan faktanya adalah sebesar 80%. Pengukuran kepuasaan pengguna sebesar 87.62% dari 21 responden. Sistem pendukung keputusan ini dapat mempermudah mahasiswa dan pengelola Jurusan Teknik Elektro Universitas Mataram dalam mengelola dan menganalisis penentuan bidang keahlian.

When a high-rise building's lights are not required because they are frequently left on, electrical energy is wasted as a result of this.Â The smart light is one of the effective ways to energy saving in a building. This study aims to create a smart light system using the ESP-Mesh network and the MQTT protocol to control the turn on/off of all lights in all rooms of a high-rise building. The ESP-Mesh network is a mesh of ESP8266 devices that are designed for multi-hop transmission. The MQTT is one of the widely used IoT protocols that allows a smartphone to control the lights in every room in a mesh topology via the internet remotely. The performance evaluation shows that a multi-hop ESP-Mesh is better than that a Single-hop ESP8266 in signal strength. The signal strength of the ESP8266 single-hop is bad. Meanwhile, the signal strength of the multi-hop ESP-Mesh is good in all rooms. Furthermore, The functional tests of the multi-hop ESP-Mesh show that although there are various broken paths caused by several disconnected nodes, all lights can be turned on or off suitably through the command from the smartphone switch. Turning off the not-required lights by smart light systems can help save energy.

Outdoor positioning is one of the important applications in the Internet of things (IoT). The usage of GPS is unsuitable for low-power IoT devices. Alternatively, it can use the LoRa devices. This research aims to find a better method as the fingerprint algorithm for determining the outdoor position using RSS LoRa. The methods used as the fingerprint algorithm were two artificial neural network models, i.e. backpropagation (BP) with four types of training methods and learning vector quantization (LVQ) with two types of training methods. The experiment results show the performance of LVQ1 better than those of LVQ2. Besides, the LVQ1 was also better than the BP method. However, both BP and LVQ2 have a performance that is almost similar to about 70 %. Both of the artificial neural network models, BP and LVQ, can be used as a fingerprint algorithm to determine quite accurate the outdoor object position.

LoRa Technology is one of the devices used on Low-Power Wide Area Networks (LPWAN), which is a viable alternative wireless communication technology for the Internet of Things (IoT). The LoRa device is meant to traverse a large distance while using minimal power. However, because it uses single-hop communication, the Gateway's farthest nodes will die prematurely as a result of the increased energy usage. This research attempts to improve the range of LoRa networks utilizing multi-hop uplink communication while also reducing energy consumption by adjusting the LoRa transmission power to the lowest possible dBm in each hop. As a network model, a star topology-based tree made of some rings with a gateway as the central point is chosen. The performance of two forms of uplink communication, single-hop and multi-hop models was tested in terms of energy consumption and coverage. The results show that the network structure in the multi-hop uplink model can extend coverage over a greater distance while using less energy than the single-hop uplink model. This model can be used as a supplement to the LPWAN's uplink communication in the IoT to enhance the network's coverage range and lifetime.

Based on WHO’s data in 2013, there are 24.5% of children under five in the world experiencing stunting. Around 80% of stunted children in the world live in 14 countries. Furthermore, based on the results of the 2018 National Basic Health Research, the stunting rate in children in Indonesia reached 30.8%. With West Nusa Tenggara being the area with the 5th highest stunting rate in Indonesia, which is 30.9%. Besides, Ketangga Jeraeng Village is one of the villages that also has the potential for stunting children. The Ketangga Jeraeng village consists of 8 hamlets and 9 Posyandu places. Based on data from the Posyandu in the Ketangan Jeraeng village, there were 1 child identified as stunted and 3 children identified as weight below the red line (WBR). 1 child was identified as stunted from Wates Hamlet. Meanwhile, the 3 WBG children came from the Ketangga Kemalik and Timuk Lauk hamlets. This activity lasts for 45 days starting from June 20 to August 3, 2022, which were conducted by the students of University of Mataram in Community Service Program (CSP). During those 45 days, CSP students in Ketangga Jeraeng Village empowered the community through socialization, Supplementary Food Provision, and capacity building for posyandu cadres. The result of this activity is an increase in knowledge related to how to prevent stunting and how important it is to provide nutritious food for children. In addition, the end result of this activity is also implemented by making nutritious Moringa pudding to prevent stunting. CSP students chose Moringa as the main ingredient in addition to having high nutrition, Moringa is also easy to find in this village so that it will make it easier for mothers to make the product.
