https://ojs.imeti.org/index.php/EMSI/article/view/11989
<p>Geopolymers have been known for decades and classified as inorganic polymers, characterized by high resistance to high temperatures. They can be successfully used for the thermal insulation of buildings, especially in the foamed form. The addition of phase change materials (PCMs) in such materials may also increase the heat capacity of the materials, therefore, using them for building cladding can increase the thermal comfort of the building and prevent it from overheating. This study tests the addition of PCMs to geopolymers by spraying and presents the results. Additionally, the study includes preliminary experience concerning the technology of applying these materials, along with selected test results that assess the properties of the produced coatings. The results indicate that the addition of PCMs in the amount of 15% can increase the heat capacity of geopolymer materials by about 150-180%, and the foamed geopolymer coatings produced have a thermal conductivity in the range of 0.07-0.09 W/mK.</p>Michał ŁachAgnieszka BąkKinga PławeckaMaria Hebdowska-Krupa

https://ojs.imeti.org/index.php/EMSI/article/view/12280
<p>The odor affects both one’s health and quality of life. This study measures and analyzes odor concentration and odor sources in ambient air, the correlation between odor gas concentration and the hedonic scale, and the design of an odor-reduction instrument. The research commenced from February to May 2022 in the small industrial area (SIA) of Magetan Regency and compost bins of Bogor City. Data was collected through chemical analysis, and the hedonic scale was measured at four points divided into radii one and two. The concentration of odor parameters in Magetan and Bogor City is below the quality standard, while the correlation between ammonia gas concentration and the hedonic scale is low. Regarding the biofilter, its odor reduction efficiency is 35% for rotten fish, 70% for goat manure, 82% for compost waste, and 47% for chicken carcasses.</p>Adinda Rizki VirginiaArief Sabdo YuwonoChusnul Arif

https://ojs.imeti.org/index.php/EMSI/article/view/12005
<p>Voltage Transients are generated in power lines and emit both low-frequency electromagnetic fields and radio-frequency radiation. This study aims to highlight its existence and detrimental effects on human health. A comprehensive literature review is presented, encompassing studies by multiple authors exploring the topic of dirty electricity, its impact on well-being, and preventative measures. The electromagnetic spectrum analysis and measurements of both electric and magnetic fields are performed on various household appliances such as hair dryers, old televisions, blenders, heaters, toasters, vacuum cleaners, and microwaves. The findings indicates that microwaves and compact fluorescent lamps (CFL) bulbs exhibit similar spectral characteristics, with high-frequency voltage transients primarily originating from these two devices. Conversely, other appliances do not generate significant high-frequency voltage transients (HFVT). Overall, dirty electricity poses a substantial risk to human health and necessitates attention to minimize its adverse consequences.</p>Saban Selim SekerOsman CerezciMuhammet Fatih BayindirOzlem Simsek

https://ojs.imeti.org/index.php/EMSI/article/view/12785
<p>Food waste is a growing concern in developing countries. This study aims to implement food waste bioconversion by utilizing black solider fly larvae for two eateries' food waste. The bioconversion process used 0.5 g of black solider fly eggs for 14 days in the six bio ponds. After 14 days, the waste, larvae, and compost are separated using sieves to measure the larvae and compost production. The bioconversion process is evaluated based on bioconversion characteristics and black soldier fly larvae and compost produced. Waste Reduction Index, Fresh Matter Consumption Rate, Dry Matter Consumption Rate, Dry Matter Rate, and Efficiency of Conversion of Digested Feed evaluated the bioconversion characteristics for reduction. According to the experimental results, utilizing BSFL is adequate for food waste management, effectively reducing up to 62.6%. Simultaneously, the fresh larvae and compost are produced within a 14-day bioconversion process. The compost meets standards for the nitrogen, C/N ratio, phosphorus, potassium, zinc, and iron content (SNI 19-7030-2004).</p>Dewi Apriliani PutriYudi ChadirinArief Sabdo Yuwono
