Abstract

Kualitas udara di ruang tertutup dapat menurun akibat akumulasi gas berbahaya dan kurangnya sirkulasi, yang berdampak negatif pada kesehatan. Exhaust fan umum digunakan sebagai solusi, namun mayoritas masih dioperasikan manual tanpa pemantauan kondisi udara. Penelitian ini bertujuan merancang prototipe sistem kendali exhaust fan otomatis berbasis Internet of Things (IoT) menggunakan sensor MQ-2 untuk deteksi gas dan sensor DHT22 untuk pemantauan suhu serta kelembapan, dengan mikrokontroler ESP32 dan platform Blynk sebagai antarmuka jarak jauh. Metode meliputi perancangan perangkat keras (ESP32, MQ-2, DHT22, relay, exhaust fan DC 12V) dan pemrograman menggunakan Arduino IDE yang terhubung ke Blynk. MQ-2 menjadi parameter utama ON/OFF kipas, sedangkan suhu dan kelembapan hanya untuk monitoring. Pengujian dilakukan dengan membandingkan pembacaan sensor terhadap alat ukur komersial, serta mengukur waktu respons sistem. Hasil menunjukkan sistem mampu mendeteksi peningkatan konsentrasi gas dan mengaktifkan exhaust fan otomatis dengan waktu respons rata-rata 2 detik. Rata-rata error suhu 0,58°C, dan kelembapan 2,15%. Data dapat dimonitor real-time di Blynk dengan opsi kendali manual atau otomatis. Sistem ini menjadi solusi ventilasi cerdas yang responsif, akurat, dan terhubung, cocok untuk rumah tangga, usaha kuliner, maupun smoking room.

Abstract

The increasing electricity consumption of the Indonesian population requires renewable energy as an alternative to electricity generation supplies. Renewable energy can be formed through mechanical energy in its simplest form, namely in the form of a footrest. Generally, energy-harvesting floors that utilise human footsteps are designed with piezoelectric sensors. This sensor is responsible for converting mechanical energy into electrical energy. However, the power generated from piezoelectrics is only around 0.041 μW to 240.59 μW. So, in this study, an alternative design for a footstep floor is proposed capable of harvesting electrical energy using a DC generator. The proposed platform consists of a platform design that utilises the translational motion of the gears on the gear rack and is assisted by four springs surrounding the sides of the iron plate. Apart from that, the platform has a power management and storage system. Unlike controllers in general, solar charger controllers are used for charging (voltage and current in the accumulator) and flowing current to the load (lights). The subjects used in this floor test ranged from 20-100 kg. Compared to floors that use piezoelectrics, the results are that floors with DC generators experience an increase in power of around 0.62%. Hence, DC generators are more effective in harvesting electrical energy.

Abstract

Used cooking oil underwent thermal and oxidative degradation due to repeated heating, resulting in increased peroxide levels and producing rancid odors, discoloration, and potential toxicity. In this study, the initial peroxide value of the used cooking oil was 56.42 meq O₂/kg, indicating significant oxidative degradation. The study evaluated the ability of activated sugarcane bagasse-bentonite (ASBB) and non-activated (SBB) composites to reduce peroxide values. Characterization was performed using SEM-EDX and FTIR, while adsorption efficiency was tested by varying the adsorbent dose (2–10 g) and treatment time (0–180 minutes). Peroxide reduction was analyzed using iodometric titration. The results showed that ASBB was more effective, with 10 g of ASBB and 180 minutes of treatment reducing the peroxide value by up to 82.3–84.5%.
