<![CDATA[Dysmenorrhoea is a common menstrual problem among adolescent girls and may interfere with daily activities and academic performance. Non-pharmacological interventions such as hot dark chocolate and herbal beverages are considered safer alternatives to manage menstrual pain. This study aimed to analyse the effectiveness of hot dark chocolate and Jesoma (ginger, soya, and honey) in reducing dysmenorrhoea pain intensity among female students at SMAN 3 Pontianak. This study employed a quantitative approach with a quasi-experimental design using two groups with pretest–posttest measurements. The sample consisted of female students who experienced dysmenorrhoea and were divided into a hot dark chocolate group and a Jesoma group. The sampling technique used was purposive sampling, with a total sample of 90 respondents, divided into 45 respondents in each group, based on calculations using G*Power with an additional 10% to anticipate dropout. Pain intensity was measured before and after the intervention using a Numeric Rating Scale (NRS) ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst possible pain. Data were analysed using the Wilcoxon test and Mann–Whitney test. The results showed a significant reduction in dysmenorrhoea pain intensity in both intervention groups (p < 0.05). The hot dark chocolate group demonstrated a moderate effect size (0.60), while the Jesoma group showed a large effect size (0.72). Comparative analysis indicated that Jesoma was more effective than hot dark chocolate in reducing dysmenorrhoea pain (p = 0.038). Both hot dark chocolate and Jesoma are effective non-pharmacological interventions for reducing dysmenorrhoea pain among adolescent girls; however, Jesoma demonstrates greater effectiveness.]]>
