In the last ten years, Indonesia has been carrying out massive infrastructure development. The goal is to facilitate community mobility which has an impact on economic growth. Infrastructure development also aims to increase the Human Development Index even though it does not directly affect it. One of the provinces that contributed to infrastructure development was East Java, with the Human Development Index during the 2018-2022 period increasing and tending to stagnate. For this reason, the purpose of this study is to identify the influence of infrastructure development on the Human Development Index, including identifying the influence of poverty on the Human Development Index. The research methodology used is quantitative with  a Geographically Weighted Panel Regression (GWPR) approach that allows to comprehensively identify the Regional Development Index in East Java. The results obtained were that the variables of Infrastructure Development with the dimensions of Road Length (6,172) and Number of Schools (2,686) had an impact on the Human Development Index in East Java. Meanwhile, the poverty variable (-6,139) has no effect on the Human Development Index (HDI). However, simultaneously the variables of Infrastructure Development and Poverty affect the National Development Index (HDI) with a calculation of 64.42 > 2.4202.

Fire is one of the incidents that disturbs homeowners because of the fire that will drain property and can claim lives when there is a lack of anticipation and minimal ignorance of the incident, such as when a fire occurs there is no early warning to the homeowner, this is also a cause of fire. The cause of the fire can be caused by a gas leak, electrical short circuit or caused by the community itself. Based on these problems, a solution is needed to create a safety system technology to be applied to the home kitchen, namely the design of an early detection system for fires based on the Internet Of Things (IoT) using ESP8266 which is useful for monitoring kitchen conditions and will automatically send a notification of the kitchen condition if the sensor reads an incident. The Hardware Design uses several tools consisting of ESP8266, Arduino R3. Jumper Cables, Fire Sensors, MQ-2 Gas Sensors, Mini Fans, Mini Water Pumps, Relays, Buzzers. and for the software design using Arduino IDE for system programming and Blynk as an application to display notifications. The designed system will be tested using black box testing which is used to determine whether the designed system will meet the specified parameters or not, and the results of the design state that the system is in accordance with the parameters used.

<p class="Text"><em>In Kendal, smoked fish producers generally use the hot smoking method, in which the fish is placed close to the smoke source and smoked for three to four hours. The upside is that it has a significant impact on supporting many human endeavors, such as in industrial fishing and food processing. While the negative impact on the environment, such as environmental damage due to global warming, and air pollution. To overcome this problem, a prototype of an environmentally friendly Electrostatic Precipitator chimney has been created. This prototype is operated using power from a Solar Power Plant (PLTS). The results of this study indicate the potential absorption of solar radiation by solar cells shows good efficiency in the first test, the efficiency of solar cells recorded the lowest value of 8.50%, the highest reached 15.76%, with an average of 13.03%. Furthermore, in the second test, the efficiency of the Solar Cell showed an increase, recording the lowest value of 12.83%, the highest reaching 17.19%, and an average of 14.72%. The best test is in the second test because the first test is cloudy and drizzling. By utilizing the intensity of solar radiation as a resource, the Electrostatic Precipitator can be operated quite well. In the two tests carried out, the average output power of solar panels reached 28.51 and 49.49 Watts. Meanwhile, for the power used as the input of the tool in the two experiments, the values recorded were 30.70 and 10.33 Watts.</em></p><p> </p><p><strong><em>Keywords</em></strong><em>: </em><em>Fumigation, Electrostatic Precipitator, PLTS (Solar Power Plant)</em></p><p> </p><p class="Abstract" align="center"><strong>ABSTRAK  </strong></p><p>Di Kendal, para produsen ikan asap umumnya menggunakan metode pengasapan panas, di mana ikan diletakkan dekat dengan sumber asap dan diasapi selama tiga hingga empat jam. Dampak positifnya adalah memiliki dampak yang signifikan untuk mendukung banyak usaha manusia, seperti di bidang indutsri perikanan dan pengolahan makanan. Sedangkan, dampak negatifnya terhadap lingkungan, seperti kerusakan lingkungan akibat pemanasan global, dan polusi udara. Untuk menangani masalah tersebut, telah dibuat sebuah prototipe cerobong <em>Electrostatic Precipitator </em>yang ramah lingkungan. Prototipe ini dioperasikan menggunakan tenaga dari Pembangkit Listrik Tenaga Surya (PLTS). Hasil penelitian ini menunjukkan potensi tingkat penyerapan radiasi matahari oleh <em>Solar Cell</em> menunjukkan efisiensi yang baik pada pengujian pertama, efisiensi <em>Solar Cell</em> tercatat nilai terendah sebesar 8,50 %, tertinggi mencapai 15,76 %, dengan rata-rata 13,03%. Selanjutnya, pada pengujian kedua, efisiensi <em>Solar Cell</em> menunjukkan peningkatan, mencatat nilai terendah sebesar 12,83 %, tertinggi mencapai 17,19 %, dan rata-rata sebesar 14,72 %. Pengujian terbaik terdapat pada pengujian kedua dikarenakan pengujian pertama terdapat cuaca mendung dan gerimis. Dengan memanfaatkan intensitas radiasi matahari sebagai sumber daya, alat <em>Electrostatic Precipitator </em>dapat dioperasikan dengan cukup baik. Pada dua pengujian yang dilakukan, rata-rata daya <em>Output </em> panel surya mencapai 28,51 dan 49,49 <em>Watt</em>. Sementara itu, untuk daya yang digunakan sebagai <em>Input </em>alat tersebut dalam dua percobaan, nilai yang tercatat adalah 30,70 dan 10,33 <em>Watt</em>.</p>
