Abstract: The effect of variation concentration of solution powder kaffir lime leaves (Citrus hystrix. dc) against the parameter of figure germ at eating utensils. The recommended disinfection process such as the use of heat and chemicals in a society generally not done because it takes a long time and expensive cost, as well as the excessive use of chemicals, can cause environmental pollution. Therefore, the necessary natural ingredients as a substitute as kaffir lime leaves. Based on the research results Sulistiyani, et al (2004) showed a rinsing by using kaffir lime leaves can decrease the number of microbes on eating utensils. This study aims to determine the effect of variation concentration of solution powder kaffir lime leaves (Citrus hystrix. DC) against the parameter of figure germ at eating utensils. This type of research is experimental, pretest-posttest design with the control group. The samples used were 42 swab samples plate tools. Methods of data collection based on the check out results from the number of figure germ (TPC) in the laboratory. Analysis of data using statistical test Paired t-test and correlation test. The results showed that the average total number of figure germs before treatment ranged from 44-73 colonies/cm2, and the average total number of figure germs after disinfection treatment with a solution of powdered kaffir lime leaves ranging between 6-50 colonies/cm2. Based Paired t-test is known that there are differences the average number of figure germ before and after treatment, where the average total number of figure germs after treatment is lower than the average number of figure germs before treatment with the percentage decrease ranging between 23-89%. Statistical analysis of the correlation test showed there is a relationship between variations in concentration of powder kaffir lime leaves with the number of figure germ on the plate. Kaffir lime leaves contain chemical compounds polyphenols, flavonoids, essential oils, tannins and alkaloids that have a pharmacological effect as an antiseptic, so it can be used as a disinfectant to wash eating utensils. Keywords: Kaffir lime leaves (Citrus hystrix. DC); figure germs.

Abstract

This study examines the construction of da'wah methodology in the Qur’an based on Imam Ibn Kathir’s interpretation in Tafsir Al-Qur’an Al-‘Azhim. The research focuses on Qur’anic verses that explain the commands, principles, and methods of da'wah practiced by the prophets and messengers. Using a library research method, this study places Tafsir Ibn Kathir as the primary source, supported by relevant tafsir works and academic literature. The findings show that the Qur’anic da'wah methodology, according to Ibn Kathir, follows a universal and consistent pattern grounded in tawhid, wisdom, good advice, and courteous dialogue. The da'wah of the prophets shares a common objective, namely inviting people to worship Allah alone, obey His commands, and follow the messengers sent to them. The novelty of this study lies in its systematic formulation of Qur’anic da'wah methodology through Ibn Kathir’s classical interpretation, revealing the continuity of da'wah principles across prophetic generations. The study also emphasizes that effective da'wah depends on the suitability of methods to audience conditions and the moral example of the da’i. Therefore, this methodological construction is both normative and practical for contemporary da'wah challenges. It strengthens understanding of prophetic communication ethics in responding to diverse social and religious contexts today. This research contributes to the development of da'wah and tafsir studies and may serve as a conceptual reference for Qur’an-based da'wah practice.
