Abstract

Deteksi dini kanker payudara merupakan langkah penting untuk meningkatkan peluang kesembuhan dan menekan angka kematian. Penelitian ini merancang sistem deteksi dini berbasis citra digital dengan memanfaatkan indikator visual berupa warna kemerahan pada kulit. Sistem dikembangkan menggunakan ESP32-Cam yang terintegrasi dengan Edge Impulse untuk pelatihan dan inferensi model klasifikasi berbasis Artificial Intelligence (AI). Deteksi dilakukan melalui pengolahan citra warna dan metode machine learning (ML) yang bekerja berdasarkan prinsip fisika optik dan sensorika, khususnya interaksi cahaya dengan permukaan kulit, serta merupakan bentuk penerapan prinsip-prinsip fisika dalam pengembangan teknologi deteksi visual modern. Dataset dikumpulkan dari phantom payudara dengan variasi tingkat kemerahan, dua jenis warna kulit (kuning langsat dan sawo matang), serta pencahayaan berbeda (600 lux, 800 lux, dan 1000 lux). Gambar diambil dari jarak 20 cm dengan sudut 90° dan 45° menggunakan kamera handphone. Model dilatih menggunakan metode CNN dan diintegrasikan ke ESP32-Cam, namun proses inferensi masih memerlukan koneksi internet untuk dapat dijalankan. Hasil menunjukkan bahwa pencahayaan 800 lux memberikan visual optimal, dan berhasil menjalankan klasifikasi dengan akurasi rata-rata sebesar 90,9%. Evaluasi menggunakan confusion matrix menunjukkan bahwa sistem ini baik dan akurat. Kata kunci: Deteksi dini; edge impulse; ESP32-cam; fisika optik; kanker payudara.

Abstract

Abstrak Pencahayaan buatan memiliki peran penting dalam menciptakan kenyamanan visual dan efisiensi energi di ruang tertutup, terutama pada bangunan publik seperti auditorium. Kualitas pencahayaan diukur melalui intensitas cahaya (lux) dan keseragaman distribusi cahaya yang sesuai dengan standar SNI 6197:2011. Standar tersebut menetapkan tingkat pencahayaan minimum sebesar 300 lux dan rasio keseragaman minimal 0,7 untuk ruang dengan aktivitas visual menengah hingga tinggi. Penelitian ini bertujuan untuk menganalisis sebaran intensitas cahaya buatan di Auditorium Budi Utomo Universitas Muhammadiyah Lamongan menggunakan alat ukur lux meter dan perangkat lunak Surfer. Pengukuran dilakukan pada 290 titik dengan jarak antar titik 60 cm dalam kondisi seluruh lampu menyala. Hasil pengukuran menunjukkan bahwa intensitas cahaya di auditorium berkisar antara 50 hingga 110 lux dengan rata-rata 84,2 lux, masih jauh di bawah standar SNI. Hasil pemetaan menggunakan Surfer memperlihatkan area tengah auditorium memiliki intensitas tertinggi, sedangkan bagian tepi depan dan belakang lebih rendah. Nilai keseragaman pencahayaan (uniformity ratio) sebesar 0,59 menandakan distribusi cahaya belum merata. Kondisi ini menunjukkan bahwa sistem pencahayaan auditorium belum optimal, baik dari segi intensitas maupun pemerataan, sehingga dapat menurunkan kenyamanan visual. Diperlukan penambahan titik lampu, penggunaan lampu berefikasi tinggi, dan penataan ulang armatur agar pencahayaan menjadi efisien, merata, dan sesuai standar nasional.   Abstract Artificial lighting plays an important role in creating visual comfort and energy efficiency in enclosed spaces, especially in public buildings such as auditoriums. Lighting quality is measured through light intensity (lux) and uniformity of light distribution according to the SNI 6197:2011 standard. The standard stipulates a minimum lighting level of 300 lux and a uniformity ratio of 0.7 for spaces with moderate to high visual activity. This study aims to analyze the distribution of artificial light intensity in the Budi Utomo Auditorium, Muhammadiyah University of Lamongan using a lux meter and Surfer software. Measurements were conducted at 290 points with a distance between points of 60 cm with all lights on. The measurement results show that the light intensity in the auditorium ranges from 50 to 110 lux with an average of 84.2 lux, still far below the SNI standard. The mapping results using Surfer show that the center area of ​​the auditorium has the highest intensity, while the front and rear edges are lower. The lighting uniformity ratio value of 0.59 indicates that the light distribution is not yet even. This situation indicates that the auditorium's lighting system is suboptimal, both in terms of intensity and distribution, which can reduce visual comfort. Additional lighting points, the use of high-efficiency lamps, and the rearrangement of fixtures are needed to ensure efficient and even lighting and meet national standards.

Abstract

East Java has various regional conditions. The condition of the area certainly has the potential for disasters that have a significant impact on the agricultural sector. Flood is one of the factors that damage agricultural land. Flood risk management plays an important role in guiding the government in making timely and appropriate decisions for flood rescue and relief. The purpose of this research is a study of flood risk assessment in the agricultural sector in East Java using Multi Attribute Utility Theory. The Multi Attribute Utility Theory is used to solve problems related to spatial planning and disaster management because it is systematic and suitable for solving complex problems such as the agricultural sector. The results showed that the agricultural land areas in East Java with the category of very flood-prone include Bojonegoro, Lamongan, Tuban, and Sidoarjo Regencies. Furthermore, the results of this study were visualized by mapping flood risk using a GIS. This can be used for efforts in flood disaster management. This research is expected to assist policy making at the Department of Agriculture and Food Security in monitoring flood-prone agricultural land in order to minimize the occurrence of flood disasters in the agricultural sector.

Abstract

This research explores facial thermal dynamics as a non-invasive indicator of emotion and physiological stress in Indonesian students during physics learning, given the prevalence of mental health issues in this demographic. Academic stress triggers the body's stress response, causing measurable changes in skin surface temperature. Analyzing these variations offers a potential biomarker to assess physiological stress and its associated mental health risks. Using a quantitative approach, the study measured the facial temperature of four participants on their forehead, nose, and lips with a Uti120s thermal camera during four distinct stages of a physics lesson, with the thermographic data subsequently analyzed via Python to calculate temperature, radiation wavelength, heat transfer, and temporal temperature gradients. The average temperature increase was recorded on the forehead: Tmin = 33,86℃, Tmax = 35,34℃,Tincrement  = 1,48 ℃,  nose : Tmin = 30,56 ℃, Tmax = 34,27℃, Tincrement  = 3.32 ℃ and lip : Tmin = 29,82 ℃, Tmax = 34,07℃, Tincrement 3,88 ℃. This temperature increase was observed during the pre-lecture and core lecture stages, then decreased after the quiz. The emitted infrared wave radiation ranges from 9.42μm (forehead), 9.47μm (nose), and 9.48μm (lips), high radiation heat transfer in the forehead area and minimal in the lip area. The temperature gradient is positive at the beginning of the lecture and negative at the end which are not visible to the naked eye but can be captured by thermal cameras as biomarkers of physiological stress. Although there were temperature changes, the detected emotions were mostly neutral, indicating that the physics learning process triggers physiological stress but does not significantly affect mental health negatively in this initial observation.
