Sunscreen aims to protect the skin from direct sun exposure. This cosmetic product is included in the type of cream. Sunscreen is made from patchouli oil as the main ingredient. The ingredients used in making the sunscreen in each package contain Niacinamide, Avobenzone, Patchouli Oil, Emulgade SE-PE, Cutina GMS SE, Isopropyl Myristate, Dimethicone, Cetiol CC, Glycerin, Phenoxyethanol, Disodium EDTA, and Aquades (ionize water). The tools used are hot plates, scales, magnetic stirrer, stirring spoons, measuring cups, baking glasses, and pipettes. This sunscreen production method is divided into two phases, namely phase A and phase B. In phase A Niacinamide and Avobenzone are mixed at a speed of 2500 rpm, Temperature 70o C for 15 minutes. In phase B, Phenoxyethanol, Disodium EDTA, and Aquades were mixed at a speed of 2500 rpm, a temperature of 70o C for 15 minutes. The next step is that the two phases are mixed at a speed of 1000 rpm, a temperature of 40o C for 10 minutes until homogeneous, then packaged. The results of the research will be carried out by laboratory tests. The indicators to be tested are organoleptic test, homogeneity test, pH test, cream irritation test and photoprotector activity test. The results of each organoleptic test of sunscreen were white, soft texture, patchouli oil aroma, stickiness on the skin was classified as sticky. Homogeneity test showed homogeneous sunscreen, the test was carried out using glass preparations. A certain amount of cream is applied to the slide and visually observed. This test was repeated three times. The cream pH test was carried out using a pH meter, carried out with a number of creams dissolved in aquades and dipped in a pH measuring instrument. Based on the irritation test, sunscreen does not cause irritation. The test was carried out in vivo, the cream was applied to the back of the hand repeatedly for 3 days to 10 respondents aged 19-22 years.

Root knots, caused by Meloidogyne spp. is among the plant pathogens that lead to significant yield loss in patchouli plants. Farmers have used synthetic nematicides to control the pathogen for many years. In fact, the chemicals not only harm the environment but also might degrade quality of agriculture products. Therefore, in this study, we examined several dosages of Bacillus thuringiensis (Bt) to control Meloidogyne spp. on Pogostemon cablin Benth. Three dosages of Bt suspension (30, 40, and 50 ml/plant) were applied to the rhizosphere to observe the incubation period, disease intensity, number of galls, and the population of nematode. The results show that 40 ml/plant of Bt significantly prolongs the incubation time, reduces the disease intensity, and the number of root-knots. None of the dosages tested showed a significant impact on the nematode population. This study showcases the potential of Bt to control Meloidogyne spp. on patchouli plants. More research is required to confirm the efficacy of this approach.
