South Sulawesi's Lake Tempe is a popular tourist site. Many foreigners, both locally and internationally, visit Lake Tempe. The quality of the guide's service has a significant impact on the smoothness and comfort of travel in Tempe. As a result, a training and mentoring program for foreign-language tourism performers in the Tempe Lake area is required. The PKM program is carried out in stages: (1) PKM participant selection; (2) PKM briefing participants; (3) survey site; (4) PKM program socialization; (5) debriefing tourist actors; and (6) twice-weekly training and mentorship for three months. In total, 25 meetings were held to provide training and mentorship. The training team enhances the vocabulary at the start of the training, and subsequently, the material and speaking are intensified by the team. The assessment's findings revealed a significant increase: (1) There were three people in the very good group, 25 in the good category, and two in the bad category when it came to vocabulary ability. (2) There are 26 persons who are classified as good at tenses, and just four people who are classified as less good. (3) In terms of speaking skill, four people were rated as very good, 25 were rated as good, and one was rated as less good.

The aim of this study was to evaluate the efficacy and safety of CAEC (Canavalia gladiata arctium lappa extract complex) in adults with white blood cells between 3 and 8 × 103 cells/µL by assessing natural killer (NK) cell activity and immune-related biomarkers. Overall, 100 participants (CAEC group = 50, placebo group = 50) were randomised, and administered CAEC or placebo once daily for 8 weeks, with an evaluation visit performed every 4 weeks. NK cell activity, the primary outcome, significantly increased in CAEC when compared with the placebo at effector-to-target (E:T) ratios of 25:1 and 50:1 after 8 weeks. Compared with the placebo group, IL-10 demonstrated significant differences at week 8 in the CAEC group. Our findings demonstrate that CAEC is safe and enhances immune function by stimulating NK cell activity through IL-10 expression. Hence, we anticipate that CAEC can be developed as a functional food for stimulating immunity.

• CAEC enhanced immune function by stimulating NK cell activity and IL-10 expression. • CAEC significantly increased NK cell activity at E:T = 25:1 and 50:1 after 8 weeks. • CAEC significantly increased the level of IL-10 after 8 weeks. • CAEC will be able to serve as a functional food for stimulating immunity.
