Abstract

Tapak dara (Catharanthus roseus) is a plant belonging to the Apocynaceae family originating from Central America and is generally grown as an ornamental plant. The purpose of this study was to determine the percentage of mortality data and the LC50 value of tapak dara methanol extract (Catharanthus roseus) against Artemia salina Leach larvae using the Brine Shrimp Lethality Test (BSLT) method. The BSLT method used consisted of 6 concentration treatments, namely 20 ppm, 60 ppm, 100 ppm, 140 ppm, 180 ppm, and 0 ppm a negative control, each of which was repeated three times. At each concentration, 10 experimental animals of 48 hours old Artemia salina Leach larvae were used. The toxic effect of the extract was identified by the percentage of mortality of Artemia salina Leach larvae using probit analysis (LC50). The results showed the linear regression equation y = 3.0809x – 12.065. This shows that the mortality of the test animals reached 50% when the compound concentration reached 34,599 ppm. Based on the toxicity test of the methanol extract of the tapak dara flower (Catharanthus roseus) using the Brine Shrimp Lethality Test (BSLT) method, in this study it was toxic because LC50>1000 ppm so it has potential as an anticancer.

The purpose of this activity is to determine the level of preference (hedonic) for a product in the form of lemon candy with a combination of lemon juice and sugarcane juice. The activity begins with making a product in the form of lemon candy from a combination of lemon juice and sugarcane juice. The activity continued with data collection using pre-test, post-test and hedonic test questionnaires. The results of filling out the pre-test showed that SMAS HKBP Sidorame students' knowledge regarding lemon candy was still lacking with the percentage of yes answers to each question namely 100%, 33.33%, 20%, 6.67%, 40%. The results of filling out the post-test showed that SMAS HKBP students' knowledge was very good with the percentage of yes answers to each question namely 100%, 77%, 97%, 93%, 93%. This shows the development and increase in knowledge of SMAS HKBP Sidorame students about lemon candy. The results of the hedonic test survey obtained the highest percentage for shape parameters of 33.33% (very like), color of 43.3% (quite like), aroma of 40% (like very much), hardness of 30% (very like) and taste of 46.67% (very like). These results indicate that SMAS HKBP Sidorame students like the preparation of lemon candy.

Abstract

Bath salt or better known as bath salt is a product that has recently been growing rapidly. Herbal bath salt itself is still not widely developed by the community. Herbal bath salts can be made from ginger powder and lemon peel which has a distinctive fragrance that can be relaxing for anyone who uses it. This community service activity involved class XI HKBP Sidorame Private High School students based on an innovative herbal bath salt preparation with a combination of ginger and lemon peel. The purpose of this activity is to determine the level of preference (hedonic) for a combination of lemon peel and ginger bath salt preparations. The activity began with the preparation of a combination of lemon peel and ginger bath salt. The activity ended with data collection using pre-test, post-test and hedonic test questionnaires. The results of filling out the pre-test showed that SMAS HKBP Sidorame students' knowledge was still lacking with the proportions for each question namely 23,33%, 6,66%, 10%, 0% and 30%. The results of filling out the post-test showed that the students' knowledge of SMAS HKBP was very good with a proportion of 100% for each question. This shows the development and increase in knowledge of SMAS HKBP Sidorame students about bath salts. The results of the hedonic test survey obtained the largest proportion for shape parameters of 56,66% (very like), color of 50% (like very much), fragrance of 70% (very like), hardness of 46,66% (very like) and ease of use of 63,33% (very like). These results indicate that SMAS HKBP Sidorame students like bath salt product.
