Millettia pinnata (L.) Panigrahi is a potential legume tree that produces seed oil for biodiesel feedstock. The initial step for raising a large-scale plantation of the species is selection of high oil yielding trees from the natural habitat. This is followed by vegetative propagation of the selected trees and then testing the growth of the clone in the field.Â The aim of the present study was to select high-oil yielding trees of M. pinnata, to propagate the selected trees by budding and to evaluate the survival and growth of budded plants in the field. Pods were collected from 30 trees in Lovina Beach, Buleleng Regency, Bali. Oil was extracted from seeds using soxhlet with hexane as a solvent.Â The high oil yielding trees were propagated by budding using root stocks grown from M. pinnata seeds.Â Scions were taken from young branches of selected trees. Incision was made on rootstock and the same size of cut was made on a scion containing a single bud.Â The scion was inserted to the incision of rootstock then closed tightly using plastic strips.Â Â The plastic was removed when the scion grew into a little green shoot. One month after plastic removal, the scion union grew into a single shoot and then the budded plants were removed to polybags. Budded plants were planted in the field of Bukit Jimbaran, Badung Regency, Bali with 4 Ã— 4 spacing. Results showed all budded plants successfully grow new shoots. Two months after planting the survival of budded plants was 100%. Plant height increased by 22.13 cm, stem diameter increased by 2.43 mm and the number of compound leaf increased by 2.08.Â It can be concluded that four high oil yielding trees were selected from Lovina Beach and successfully propagated by budding. Survival of budded plants was 100% with vigorous growth.

Staphylococcus epidermidis infections of the skin can cause boils, itching and long-lasting sores. Currently, around 75% to 90% of S. epidermidis infection cases are resistant to the antibiotic methicillin. Thus, this becomes a concern in the health sector. This research aims to discover a new method to treat S. epidermidis infection by using lactic acid bacteria as its opponent, so that the use of antibiotics can be reduced. The physical test includes confirmation of Lactic Acid Bacteria (LAB), inhibition test of lab on S. epidermidis, lotion formulation, organoleptic and homogeneity test of lotion, lotion hedonic test, LAB total plate count test in lotion, and data analysis using Microsoft Excel, Statistical Program Service Solution (SPSS), and ANOVA test. Lactic acid bacteria isolates were obtained from previous research stocks and tested for their ability to inhibit S. epidermidis in vitro. These lactic acid bacteria were added to the lotion. The favorability level of consumers to the lotion was also tested. The results indicated that lactic acid bacteria were able to inhibit the growth of S. epidermidis and remained effective until the seventh day. In addition, respondents provided a positive response to the physical quality of the lotion that contained lactic acid bacteria.

This study produced biodiesel from Malapari seed oil (Pongamia pinnata L.) by optimizing the esterification and transesterification processes. The objectives of this study were to determine the sulfuric acid (H2SO4) catalyst concentration in the esterification reaction that can reduc the free fatty acid (FFA) content of the seed oil to ≤2%, analyze the oil to methanol molar ratio (i.e.,1:6, 1:9, and 1:12) and KOH concentration (i.e.,2%, 4%, and 6%) that will produce the highest biodiesel yield, and evaluate the quality of the produced biodiesel according to the Indonesian National Standar (SNI) 04-7182-2015. The research was conducted from October to December 2023 at the Plant Physiology Laboratory and the Physical Chemistry Laboratory, FMIPA, UNUD. The research applied Completely randomized design. Quantitative biodiesel data were analyzed using Analysis of Variance. If significant differences (α < 0.05) were detected, then the quantitative biodiesel data were further analyzed using Duncan's Post Hoc Test. Results showed that an H2SO4 concentration of 7% reduced the FFA content to 1.915%. A molar ratio of 1:12 with a 2% KOH catalyst produced the highest biodiesel yield of 65.35%. The produced met the SNI for the saponification number (i.e., 52.82–133.69 mg-KOH/g), iodine number (i.e.,7.19–22.42 g_I2/100_g), and cetane number (i.e., 86.48–132.68). However, the water content (i.e., 0.721%–2.407%), viscosity (i.e., 1.73–6.18 mm²/s), acid number (i.e., 0.224–4.685 mg_KOH/g), density (i.e., 874–917 kg/m³), FFA content (i.e., 0.116 -% to 2.229%), and methyl ester content (48,13% to–132.12%_mass) partially did not meet the standards. This study highlights the potential of Malapari seed oil as a biodiesel feedstock, with further required needed to meet all quality standards.

Black rice contains antioxidants that neutralize free radicals, helping prevent wrinkles and skin damage. Fragrant lemongrass produces essential oils with citronellal, geraniol, and citronellol, which have antibacterial effects. This study aims to develop and evaluate a face mask combining black rice extract and citronella essential oil to nourish, cleanse, and tighten the skin. Masks were formulated with black rice concentrations of 30%, 40%, and 50%. Evaluations included phytochemical screening, antioxidant activity (DPPH assay), organoleptic properties, pH, homogeneity, dispersibility, and physical stability. Black rice extract showed antioxidant content of 0.037 mg/L, while the mask formulations exhibited strong antioxidant activity at 2.231 mg/L. The FII mask met Indonesian National Standard (SNI) criteria for physical stability. Clinical tests from week 2 to 6 on volunteers revealed that the FIII mask improved skin firmness, reduced acne and black spots, and increased moisture. This research demonstrates that combining black rice antioxidants with citronella essential oil produces an effective natural face mask that enhances skin health.
