Telah dilakukan sintesis dan karakterisasi membran ZSM-5 dengan penyangga kasa jenis 304 ukuran 200 dan 400 mesh dan jenis kasa AISI 316 ukuran 180 mesh. Tujuan penelitian ini adalah mensintesis membran ZSM-5 dengan penyangga kasa jenis 304 ukuran 200 dan 400 mesh dan jenis kasa AISI 316 ukuran 180 mesh dan mengkarakterisasi membran ZSM-5 hasil sintesis. Sintesis membran dilakukan dengan cara melapiskan prekursor ZSM-5 (coating) pada penyangga kasa yang telah diberi perlakuan dan dipanaskan pada suhu 90 °C selama 4 hari. Selanjutnya, membran yang dihasilkan dikarakterisasi engan metoda X-ray diffraction (XRD), scanning electron microscope-energy dispersive spectroscopy (SEM-EDS) dan Fourier-transform infrared (FTIR). Hasil citra SEM-EDS menunjukkan bahwa ukuran membran ZSM-5 yang semakin besar, menghasilkan jumlah lubang atau pori semakin banyak dengan luasan pori yang semakin kecil. Pola difraksi XRD menunjukkan bahwa membran yang dihasilkan mempunyai intensitas tertinggi pada 2 8º dan 23º yang merupakan karakteristik dari ZSM-5. Hasil spektra FTIR menunjukkan adanya serapan pada bilangan gelombang 450 cm-1yang merupakan ciri khas membran ZSM-5.Characterization of ZSM-5 Membranes Synthesized by Variation of Support Types and Sizes. Synthesis and characterization of ZSM-5 membrane were carried out with 304 type 200 and 400 mesh gauze supports and 180 mesh AISI 316 gauze types. The purpose of this study was to synthesize ZSM-5 membrane with 304 type 200 and 400 mesh gauze support and AISI 316 type 180 mesh size 180 mesh and characterize the synthesized ZSM-5 membrane. Membrane synthesis was carried out by coating the pre-treated gauze support with the ZSM-5 precursor and was heated at 90 °C for 4 days. Furthermore, the resulting membrane was characterized by X-ray diffraction (XRD), scanning electron microscope-energy dispersive spectroscopy (SEM-EDS) dan Fourier-transform infrared (FTIR). The SEM-EDX analysis shows that the increasing of ZSM-5 membrane size allowed pores number to increase with smaller pore surface area. The X-ray Diffraction pattern (XRD) shows that the resulting membrane has the highest intensity at 2 of 8º and 23º as the characteristics of ZSM-5. The FTIR spectra results show absorption at wavenumbers 450 cm-1 which is a characteristic of ZSM-5 membranes.

Well water is one of the main water sources to meet the needs of the community, especially in rural areas. However, the quality of well water often does not meet health standards because it contains heavy metals such as iron (Fe). Therefore, a simple and environmentally friendly alternative technology is needed that can be utilized by the community. One method used is filtration using natural adsorbent media, one of which is coffee shell charcoal. This study aims to determine the effectiveness of coffee shell charcoal in reducing Fe levels in well water. The research design used was a true-experimental with a one-group pre-test and post-test. Well water samples were tested for Fe levels before and after filtration using coffee shell charcoal with varying media thicknesses (40, 50 & 60 cm) and contact times (30, 45 & 60 minutes). Laboratory analysis was carried out using the Atomic Absorption Spectrophotometry (AAS) method. The results showed that the average percentage of Fe reduction reached 75,36%. Media thickness and contact time significantly affected the effectiveness of Fe reduction with p values of 0,03 and 0,01, respectively (p < 0,05). A medium with a thickness of 60 cm and a contact time of 60 minutes provided the most optimal results, with final Fe levels below the threshold set by Minister of Health Regulation No. 32 of 2017 (≤ 1 mg/L). In conclusion, coffee husk charcoal has proven effective as a simple filtration medium for reducing Fe levels in well water.

These conditions may also have implications for adolescent mental health, particularly given the reported prevalence of mild (26.5%), moderate (13.2%), and severe (11.8%) depressive symptoms. Physical activity and exercise may provide a dual benefit by improving physical fitness and supporting psychological well-being. Objective: This community-based intervention aimed to improve adolescents’ knowledge of healthy lifestyle practices and strategies for maintaining and improving physical fitness as a foundation for disease prevention and mental health promotion. Method: The intervention was conducted among students at Al-Mukmin Islamic Boarding School, Tembarak, Temanggung, Indonesia, through structured health education and socialization focusing on healthy lifestyle practices and physical fitness improvement. Knowledge was assessed before and after the intervention using a questionnaire scored on a 0–100 scale. Descriptive analysis was performed using minimum, maximum, and mean scores, with changes in knowledge quantified as percentage improvement. Result: The baseline knowledge score ranged from 50 to 75, with a mean of 62.5. Following the intervention, scores increased to a range of 75–90, with a mean of 82.5. The mean score increased by 20 points, corresponding to a 32% improvement. The minimum and maximum scores increased by 50% and 20%, respectively, indicating an overall improvement in students’ understanding of healthy lifestyle practices and physical fitness. Conclusion: Structured health education focusing on healthy lifestyle practices and physical fitness was associated with improved knowledge among adolescents. Integrating health literacy with physical activity promotion in school and boarding-school settings may provide a feasible strategy for strengthening preventive health behaviors and supporting adolescents’ physical and mental well-being. Sustained and behavior-oriented interventions are warranted to translate improvements in knowledge into long-term healthy lifestyle practices.
