Abstract

This research aims to develop computational visualization of the wave function and probability distribution of particles in a one dimensional infinite potential well. The wave function is obtained analytically from the time-independent Schrödinger equation and then normalized to give it probabilistic meaning. Numerical simulations are carried out using Python with the NumPy library for computation and Matplotlib for visualization, allowing manipulation of parameters such as box length and quantum number. The visualization results confirm the basic concepts of quantum mechanics, namely quantized energy levels, sinusoidal wave function forms with a specific number of nodes, and probability distributions that have several peaks and are always positive. The simulation also shows the correspondence between wave-function nodes and zero-probability points, as well as the increasing complexity of oscillations and variations in probability distributions as the quantum number increases. These findings are consistent with theoretical predictions and show that the computational approach is effective in visualizing abstract concepts in quantum mechanics, thereby clarifying the relationship between mathematical formulation and its physical interpretation.

Abstract

Kebakaran lahan gambut di Sumatera Selatan, khususnya di Kabupaten Ogan Ilir, berdampak signifikan terhadap kualitas udara melalui pelepasan polutan berbahaya seperti karbon monoksida (CO) serta perubahan kondisi mikroklimat berupa suhu dan kelembaban. Penelitian ini bertujuan merancang dan menguji detektor portabel berbasis mikrokontroler ESP32 untuk memantau konsentrasi CO, suhu, dan kelembaban pada kondisi pascakebakaran. Sistem ini memadukan sensor MQ-7 dan DHT11, modul pencatat waktu RTC DS3231, serta penyimpanan data otomatis menggunakan MicroSD. Pengukuran dilakukan selama delapan jam pada area lahan gambut pascakebakaran di Ogan Ilir. Hasil menunjukkan bahwa CO masih terdeteksi dalam rentang 0,20–0,28 ppm meskipun kebakaran telah berakhir hampir satu bulan sebelumnya. Analisis mikroklimat memperlihatkan hubungan negatif kuat antara suhu dan kelembaban (r = –0,90). Validasi terhadap sistem pemantauan referensi menunjukkan korelasi sangat tinggi untuk suhu (r = 0,995), kelembaban (r = 0,999), dan CO (r = 0,84), menegaskan bahwa detektor portabel ini mampu menangkap pola fluktuasi lingkungan secara akurat. Temuan ini menunjukkan bahwa sistem berbasis ESP32 layak digunakan sebagai perangkat monitoring lingkungan berbiaya rendah pada wilayah rawan kebakaran lahan gambut.   Kata kunci: kebakaran lahan gambut, karbon monoksida, suhu, kelembaban, ESP32.
