Abstract

Disasters such as earthquakes, tsunamis, floods and others always cause losses in the form of material, psychological can also cause casualties. To avoid the occurrence of greater losses, an early disaster warning and information system is needed to provide opportunities for self-rescue so that losses can be minimized. The basic concept of the Internet of Things (IoT) "wherever, whenever and however" and connected to the internet is very suitable when applied to detect and early warning of natural disasters. This tool will monitor the water level using a water level float sensor and detect vibrations with the SW-420 vibration sensor module. when the water exceeds the height of the water level sensor, the data will be processed by the Arduino programmed using the Arduino IDE then the data is sent to the NodeMCU 8266-12E to send data notifications to the user. The reading results can be seen on the Telegram smartphone application.

Abstract

Logika fuzzy merupakan perluasan dari penalaran tradisional, di mana x adalah salah satu anggota dari himpunan A atau tidak, atau sebuah x dapat menjadi anggota himpunan A dengan derajat keanggotaan (μ) tertentu. Kemampuan model fuzzy dalam memetakan nilai kabur menjadi alasan penggunaan model inferensi fuzzy dalam berbagai kasus yang menggunakan nilai kabur untuk menghasilkan suatu output yang jelas atau pasti. Dalam penelitian ini akan dilakukan analis tingkat akurasi yang dihasilkan model inferensi fuzzy Sugeno dan Mamdani dalam memprediksi laju inflasi di Kota Medan, hasil prediksi akan dianalisis tingkat akurasinya dengan membandingkan hasil yang diperoleh model fuzzy inferensi Sugeno dan Mamdani dengan nilai aktualnya. Hasil dari analisis yang dilakukan untuk model fuzzy Sugeno tingkat akurasi dipengaruhi nilai regresi linier berganda sedangkan tingkat akurasi dari model fuzzy inferensi Mamdani dipengaruhi oleh ketepatan nilai masukannya. Hasil akhirnya model fuzzy Mamdani lebih akurat dibandingkan dengan model fuzzy inferensi Sugeno dalam uji kasus laju inflasi di Kota Medan.

Abstract

In the current digital era, the administrative system that still uses the conventional (manual) method is very outdated. Especially in the case of the village administration system as a provider of information services where the conventional method is an inefficient and costly way. The demand for fast, precise and accurate village information services is the reason why it is necessary to implement a web-based village information system. Ease of management and speed of transactions such as writing letters at the village office are other supporting reasons. To support these reasons, the use of a web-based village information system seems to have become a necessity to avoid errors, such as letters that have been made but have not been recorded. And as an effort to integrate manual and electronic procedures, a combination of human and machine work systems. With the existence of a web-based village information system, village communities are expected to get convenience in making letters or administration because the process is easier and more efficient.

Abstract

The use of electrical energy that is not used as needed will lead to wastage of electrical energy. Research on the application of the Internet of Things for controlling electrical equipment specifically for the electric load of lighting lamps on the first floor of Building C, the Department of Electrical Engineering, Medan State Polytechnic aims to implement an IoT system for controlling electric lighting with scheduling mode, remote control mode via internet network and light sensor mode. Thus controlling electrical equipment, in this case lighting, can be done easily through automation of the IoT system at any time and anywhere. The specific target to be achieved in this research is implementing an IoT system for controlling lighting electrical equipment in scheduling mode, remote control mode via the internet network and light sensor mode. The method used in this research is the experimental method, which collects data from observations and designs, which is then tested. The research output target is applied vocational products that are implemented in the Department of Electrical Engineering, Medan State Polytechnic. the equipment used is PZEM 004T Sensor, Photocell, RTC DS 3231, NodeMCu ESP 8266, Triac BT 136, MOC3021 Triac Driven Optoisolator, Contactor, Relay, Photocell, CT and other supporting equipment
