MSMEs, particularly producers of *kerupuk kemplang* from Palembang, often face challenges in managing kitchen smoke generated during production. This smoke not only pollutes the air and poses health risks to workers but also reduces comfort and productivity. Therefore, this study aims to design an Internet of Things (IoT)-based control system using the Fuzzy Tsukamoto algorithm to automatically regulate the exhaust fan speed based on temperature, smoke concentration, and carbon monoxide (CO) levels. This system introduces technological innovation to enhance efficiency and productivity in MSME kitchen management. The method involves using MQ135, MQ7, and DHT11 sensors to detect kitchen environmental conditions in real time. The collected data is processed by the NodeMCU ESP8266 microcontroller using the Fuzzy Tsukamoto algorithm and is then used to adjust the exhaust fan speed via an AC dimmer. The monitoring results are displayed on the Blynk IoT application for easy access. The study results show that the system successfully reduces smoke concentration by up to 30 ppm and CO levels by 40 ppm while maintaining the kitchen temperature within an optimal range of 49°C to 55°C. With a Mean Absolute Percentage Error (MAPE) of 7.66% and an accuracy rate of 92.34%, the system proves to be effective and responsive to changes in kitchen environmental conditions. The implementation of this Fuzzy Tsukamoto and IoT-based system has a positive impact on improving air quality, ensuring worker health, and increasing MSME productivity. Additionally, this system supports a more modern, efficient, and environmentally friendly kitchen management approach, making it an innovative solution for the *kerupuk kemplang* production industry

Phase Change Material is one form of renewable energy utilization that can be applied to the walls of a house to support the work of the AC to be more efficient. This material works by absorbing solar heat energy, storing it, then releasing it out so that the wall does not conduct heat into the room which will affect the workload of the AC. Lauric and stearic fatty acids are one of the superior PCM forming materials. In this study, PCM was made using a mixture of eutectic fatty acids modified with lactic acid. The method used is the direct mix method (direct mixing). PCM fatty acid materials (Laurate-Stearate) are combined into a binary mixture of eutectic fatty acids at a composition of 86%: 14% w/w. Furthermore, modifications are carried out with poly lactic acid (P) in three composition variations (L-S):P, namely (0.5: 1), (0.7: 1.0), (0.9: 1.0). Samples will be prepared in a laboratory scale model and their energy analysis will be carried out. Based on DSC testing, it was concluded that the highest latent heat was achieved by sample LSPb with a value of 101.53 J/g. The second place was taken by sample LSPc, followed by LSPa and the lowest latent heat was sample GLSP0. In line with this, the lowest melting point as an indication that PCM can withstand hot air temperatures is also found in sample LSPb . Among the four test samples, TGA data showed that sample LSPb was the sample that had the best thermal stability among the other samples with the furthest onset and endset values and the smallest % weight loss with values of 154.60 oC, 191.11 oC and 3.87% weight loss, respectively. The use of 0.7 times the amount of poly lactic acid to the eutectic mixture can absorb heat best. However, the excessive amount of poly lactic acid added actually causes a decrease in the absorption capacity and the ability to maintain heat in the PCM sample. The eutectic mixture of lauric and stearic fatty acids and the addition of poly lactic acid in the gypsum matrix successfully formed PCM which can be a candidate for room temperature control material in energy-efficient building wall applications.
