Abstract

Latar belakang masalah dalam penelitian ini adalah hasil penelitian diperoleh hasil bahwa ada hubungan yang signifikan antara status gizi dengan perkembangan motorik siswa. Hal ini berdasarkan hasil uji korelasi status gizi dengan perkembangan motorik siswa menunjukkan bahwa ada korelasi antara status gizi siswa dengan perkembangan motorik siswa dengan koefisien korelasi 0,696. Dengan koefisien korelasi sebesar 0,696 tersebut menunjukkan bahwa kekuatan korelasi antara status gizi dengan perkembangan motorik siswa tergolong tinggi karena besarnya koefisien korelasi lebih dari 0,5. Hasil analisis koefisien korelasi sebesar 0,696 juga menunjukkan bahwa arah korelasi antara status gizi dengan perkembangan motorik siswa adalah positif, hal ini dapat katakan bahwa status giziberbanding lurus dengan perkembangan motorik siswa. Artinya bahwa jika status gizi meningkat maka akan dikuti meningkatnya perkembangan motorik siswa dan sebaliknya. Dan hasil uji koefisien determinasi menunjukkan harga R2: 0,484. Hal ini berarti variabel status gizi memberi sumbangan terhadap perkembangan motorik siswa sebesar 0,484 atau 48.4%, sedangkan sisanya dipengaruahi oleh faktor lain. Pengaruh yang diberikan oleh status gizi terhadap kinerja termasuk dalam kategori cukup. Hal ini memberikan gambaran bahwa tinggi rendahnya perkembangan motorik siswa dipengaruhi oleh status gizi. Perkembangan motorik siswa yang tinggi dipengaruhi oleh adanya status gizi yang tinggi pula.

Abstract

A data center is a vital component of Information and Communication Technology (ICT) infrastructure that requires continuous physical environmental monitoring, particularly for temperature and humidity. These parameters significantly affect the stability and longevity of server equipment. Therefore, a monitoring system with high accuracy, reliability, and rapid response capability is essential. This study aims to design and develop an integrated temperature and humidity monitoring system using a Raspberry Pi 5 as the control unit, employing a DHT22 sensor to measure environmental conditions. The collected data is stored in a MariaDB database, visualized through a Grafana dashboard, and complemented with automated notification delivery via the Discord platform. The implementation and testing were conducted at the Data center managed by the Department of Communication and Informatics of the Special Region of Yogyakarta. The system supports real-time monitoring, alerts when environmental parameters exceed defined safety thresholds, and automated daily reports sent to a designated Discord channel. The research follows an engineering-based system development method, comprising stages of literature study, needs analysis, system design, implementation, testing, and evaluation. The testing results indicate that the system performs accurate sensor readings (within a tolerance range of ±0.4°C for temperature and ±1.4% for humidity) and successfully stores data periodically in the database. It also reliably sends automatic alerts to Discord when temperature or humidity levels exceed the specified thresholds (18–27°C and 30–60% RH) and delivers visual dashboard reports twice daily on a schedule. This monitoring system is expected to support the operational team of the Data center in managing environmental security more effectively and responsively
