ABSTRAK

Dewasa ini, lampu masih dihidupkan secara manual dengan menggunakan

saklar yang bisasanya terpasang di dinding. Namun, dengan sistem

penggunaan lampu secara manual ini menimbulkan suatu masalah baru.

Dimana masalahnya adalah sering kali lupa mematikan dan menyalakan

lampu sesuai dengan keadaan lingkungan. Kemudian juga intensitas cahaya

yang dikeluarkan oleh lampu yang hanya memiliki dua keluaran yaitu

menyala (terang) atau mati (gelap) masih dirasa belum optimal. Karena ada

suatu keadaan dimana lingkungan hanya sedikit membutuhkan cahaya dari

lampu tersebut. Sifat malas manusia pun ikut andil mengapa lampu belum

dimatikan padahal keadaan lingkungan sangat berlimpah cahaya. Dengan

adanya permasalahan tersebut diatas, tentunya dibutuhkan suatu sistem yang

dapat menanggulangi masalah yang terjadi. Sehingga sistem mampu bekerja

secara otomatis guna mengatur intensitas cahaya yang dikeluarkan oleh

lampu berdasarkan keadaan intensitas cahaya pada lingkungan. Dimana

sistem ini akan menggunakan dua jenis sensor utama sebagai parameter untuk

mengatur intensitas cahaya yang dikeluarkan oleh lampu. Sensor yang

digunakan adalah sensor PIR (Passive Infra Red) dan sensor LDR (light

dependent resistor). Metode yang digunakan untuk penyelesaian masalah

adalah dengan Fuzzy Logic dengan inferensi sugeno dan defuzziifikasi

weight-average method dapat menghasilkan keluaran yang tepat. Nilai MSE

yang didapat pada kondisi sangat gelap dan sangat terang adalah 0.

Sedangkan nilai MSE pada saat kodisi redup adalah 0,38044, sedang 0,44791

dan terang 0,67898.

Kata Kunci: Fuzzy Sugeno, PIR, LDR

FUZZY IMPLEMENTATION IN AUTOMATIC MULTISENSOR

LIGHTS BY SUGENO METHOD

ABSTRACT

Today, the lights are still turned on manually by using a switch that is usually

installed on the wall. However, with the system of using lights manually this creates

a new problem. Where the problem is often forget to turn off and turn on the lights

according to environmental conditions. Then also the intensity of the light emitted

by a lamp that only has two outputs which are on (bright) or off (dark) is still not

optimal. Because there is a situation where the environment requires only a little

light from the lamp. The laziness of humans also contributes to why the lights have

not been turned off even though the environment is very abundant in light. With the

problems mentioned above, of course a system is needed that can overcome the

problems that occur. So that the system is able to work automatically to regulate

the intensity of light released by the lamp based on the state of light intensity in the

environment. Where this system will use two main sensor types as parameters to

regulate the intensity of the light released by the lamp. The sensors used are PIR

(Passive Infra Red) sensor and LDR sensor (light dependent resistor). The method

used to solve the problem is Fuzzy Logic with sugeno inference and defuzziification

of weight-average method can produce the right output. The MSE value obtained

in very dark and very bright conditions is 0. While the MSE value at the dim

condition is 0.38044, medium is 0.44791 and bright is 0.67898.
