Makanan yang beredar dibeberapa wilayah di Jawa Barat diduga mengandung Bahan Tambahan Pangan (BTP) yang berbahaya. Zat aditif pada makanan digunakan untuk mempertahankan kualitas suatu zat pangan. Penelitian ini dilakukan untuk mengetahui pengetahuan masyarakat mengenai fungsi dan bahaya yang ditimbulkan oleh penggunaan zat aditif. Metode yang digunakan adalah observasi dan survei lapangan dengan teknik ceramah, tanya jawab, demonstrasi, dan penyebaran angket dengan beberapa sasaran di wilayah di Jawa Barat dengan subjek penelitian yaitu remaja dan ibu-ibu. Hasil penyebaran angket menunjukkan bahwa sebagian masyarakat ada yang masih keliru dalam memahami fungsi penggunaan zat aditif sehingga perlu adanya tindak lanjut masyarakat yang mulai membiasakan diri untuk memilah dan memilih jajanan yang sehat dengan memperhatikan kondisi fisik makanan. Masyarakat juga mulai terbiasa untuk menggunakan zat aditif alami dibandingkan zat aditif buatan karena lebih terjamin kualitas dan kesehatannya bagi tubuh.

This article analyses the educational thought of Abu Al-Hasan Ali Al-Nadwi (d. 1999 A.D.). The study aimed to determine the concept of the Sirah education curriculum at the junior high school level, according to Abu Al-Hasan Ali Al-Nadwi. This type of research is categorized as library research, with data obtained from Al-Nadwi's books relating to Sirah and education in particular such as Al-Tarîq ilâ al-Madînah; Sîrah Khâtim al-Nabiyîn li al-Atfâl; Al-Sîrah Al-Nabawiyyah; Muslims in the West, Message, and Mission. The methods used in this study are descriptive research, qualitative research, and basic research. Based on the study results, two main thoughts about Sirah's education were found. First, the continuity of Sirah Education is essential, which means that Sirah education is taught for all generations. Furthermore, Sirah education means integrating Sirah education in subjects, especially religious aspects. The author's findings on the concept of the Sirah education curriculum at the junior high school level, according to Abu Al-Hasan Ali Al-Nadwi, are a set of objectives, programs, processes, and evaluations of Sirah education up to the junior high school level that can be given from class VII to grade IX junior high school. With the existence of Sirah Education, which aims to make the Prophet Muhammad Sallallahu 'Alaihi Wa Sallam an example for junior high school students, it is hoped that it can shape the Islamic personality of students at the junior high school level and give birth to Akhlaq al Karimah based on Tawhid.

The hydrothermal method has effectively synthesized hydroxyapatite (HA). This study aimed to analyze the effect of pH on the properties (purity, crystallinity, and size) of HA crystals. HA synthesis of chicken eggshells was carried out using the hydrothermal method at temperatures of 230 °C with pH 9 and 9.34. The characteristics of HA are determined by XRF, XRD, FTIR, and TEM. The composition of the most significant compound obtained from the results of XRF analysis is CaO (97.5%). The XRD analysis showed that the purity of HA with pH 9.00 and 9.34 obtained was 97.8 and 96.6%, with the crystallinity of 56.46 and 56.96%. It was also obtained that the size of crystal HA was 21.8 and 15.7 nm for samples synthesized at pH 9.00 and 9.34. The results showed that the purity and size of HA were affected by differences in the pH synthesis and were relatively the same for its crystallinity which directly affects the value lattice parameter. The properties of HA produced by the hydrothermal method have met the criteria for biomedical applications.

Hydroxyapatite (HA) has garnered significant attention as a versatile biomaterial with promising applications in drug delivery systems. This study aimed to synthesize and characterize HA derived from eggshells using the hydrothermal method and explore its potential insights for drug delivery systems. We delivered a step-by-step process to produce HA using a hydrothermal method, supported by several analyses, X-Ray Diffraction (XRD) to analyze the crystallinity structure, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Particle Size Analyzer (PSA), and Brunauer-Emmett-Teller (BET). The stage is continued with a study on the potential of HA as a drug delivery system with UV-Visible spectrophotometer instrumentation. The results suggest that the characterized HA suits drug delivery systems due to its favorable properties. This study contributes to the understanding of utilizing hydroxyapatite from eggshells as a viable material for drug delivery systems, opening avenues for further research and development in this field.

Hydroxyapatite (HA) was successfully synthesized using the hydrothermal method. This study aimed to analyze the effect of a low solid/liquid ratio on the properties of HA crystals. HA synthesis was performed using chicken eggshells and the hydrothermal method at a temperature of 150°C. The solvent amount was kept constant, while the solid amount varied (half-reaction). The characteristics of HA were determined using XRD, FTIR, PSA, and SEM. The results showed that the purity and size of HA were influenced by a low solid/liquid ratio, while the crystallinity remained relatively unchanged, directly impacting the lattice parameter value. FTIR analysis revealed the absence of the O-H group in the sample with the low solid/liquid ratio. PSA results showed a smaller particle size of 0.995 µm for the sample with the low solid/liquid ratio. SEM results demonstrated a smaller particle size in the sample with a low solid/liquid ratio when observed at the same magnification
