Abstract

SrTiO3 thin layer were synthesized through solvothermal method by using FTO (fluorine-doped tin oxide) glass as a conductive substrate. The raw materials strontium nitrate (Sr(NO3)2) and titanium tetra isopropoxide (TTIP) were dissolved in ethanol solvent. Sample purity, elemental compositions and surface morphology were characterized using x-ray diffraction (XRD), energy dispersive x-ray (EDX) and scanning electron microscopy (SEM). XRD analysis showed that the synthesized SrTiO3 thin layer at 200oC for 24 hours with the addition of CTAB and TBA had intensity peaks that mathced the SrTiO3 standard (ICSD #94573) with perovskite structure. This result was supported by the XRD pattern of the sample powder. The EDX spectrum showed that titanium and oxygen were in the sample, but the presence of strontium was not found, due to its weak intensity. Based on the SEM image, the morphology seen is distributed equally and the grain size is rather smaller in the sample with the addition of CTAB and TBA.

Abstract

Plastic is a synthetic polymer material that can be shaped and used in various functions, especially in household products, ranging from plates, glasses, spoons, cooking utensils to food storage containers. According to research, the use of plastic that does not meet the requirements can cause serious health problems such as cancer. Plastic waste is also difficult to decompose or degrade and takes up to hundreds of years to be completely decomposed by soil microorganisms. The purpose of this community service is to provide education to housewives about plastic and the dangers of plastic use for health and the environment. This service was carried out on August 30, 2025 in RT 04 RW 01 Mendalo Indah Village, Jambi Luar Kota District, Muaro Jambi Regency, Jambi Province. The implementation of the socialization was carried out in several stages, namely: 1) Preparation Stage including a pretest to determine the initial level of understanding of participants 2) Implementation Stage including the presentation of materials and distributing brochures to participants 3) Mentoring Stage where participants were given various other alternatives to avoid the use of plastic in everyday life and 4) Success Stage The activity was carried out by analyzing the data processing of the number of answers of each participant to each instrument 'Use of Plastic Packaging Products in Everyday Life'. The aspects of assessing the success of the activity consisted of high, medium and low. The instrument for the level of success of the activity was made with the answer 'yes' or 'no. And after the mentoring process, data on respondents' understanding of the socialization activity was obtained with high success indicator results compared to before the socialization. In conclusion, socialization of the dangers of plastic use is a critical step in minimizing problems with health and environmental pollution. By increasing public awareness, it is hoped that there will be changes in behavior and real actions in reducing the use of single-use plastics and those that do not meet SNI standards.

Abstract

Community awareness regarding the safe use of food additives in packaged foods remains relatively low, particularly in understanding the differences between safe and harmful additives and the importance of reading nutritional labels. This condition was also identified among residents of RT 11/RW 03 Valencia Housing Complex, Mendalo Indah Village, Jambi Luar Kota District, where the consumption of packaged and instant foods was relatively high, especially among housewives and children. Therefore, this community service activity aimed to improve public understanding of the hazards of excessive use of synthetic food additives and increase awareness regarding safe food selection. The program was conducted using an educational and participatory approach involving 20 housewives aged 30–60 years. The implementation stages consisted of preparation, educational activities, assistance, and evaluation. Educational materials were delivered through interactive presentations, brochures, discussions, and direct practice in identifying food additives through packaged food labels. The effectiveness of the program was evaluated using pretest and posttest questionnaires. The results showed a significant improvement in participants’ understanding after the educational activities. Participants demonstrated better knowledge regarding the functions of food additives, the hazards of borax use, the identification of potentially harmful additives, and the importance of reading product composition labels. The activity also increased participants’ awareness of selecting safer food products and encouraged healthier consumption behavior within the community.
