Abstract

Noni juice can inhibit the growth of Escherichia coli bacteria. Noni juice extraction needs concentration to extract so that the preparation is more stable in the storage process. The purpose of this study was to determine the antibacterial activity and the amount of the minimum inhibitory concentration of noni juice extract from E. coli bacteria in vitro. This type of experimental research with a completely randomized one-way design. The extract was obtained by concentrating the Noni leaf extract. Extract quality control parameters include organoleptic, yield, drying shrinkage, and qualitative tests of flavonoid and anthraquinone compounds. Antibacterial activity test using the disc diffusion method with an extract concentration of 1.56%; 3.12%; 6.25%; 12.5%; and 25% with 3 replications. Positive control of amoxicillin and negative control of distilled water. Inhibition is known from the zone formed around the paper disc. The data obtained were statistically analyzed using Kruskall Wallis followed by Mann Whitney with a 95% confidence level. The results showed that the variation in the concentration of the noni juice extract had a significant effect (p <0.05). The biggest inhibitory zone was seen at 25% concentration of 10.16 mm and included in the strong category. The minimum inhibitory power was produced at a concentration of 3.12% at 2.50 mm with a weak treatment category.

Abstract

Red spinach leaves contain flavonoid, tannin, alkaloid, saponin and terpenoid that have potential as antifungal compounds. This research isĀ  experimental. The purpose of this reserach is is to find out extract red spinach leaves can inhibit the growth of Pityrosporum ovale and to find out that red spinach leaf extract can be formulated in shampoo. Extraction was carried out using the remaceration method with 70% ethanol solvent and then tested for phytochemical content. Antifungal activity testing of red spinach leaf extract using concentrations of 15; 30; 45; 60 and 75% using the well method with PDA media incubated at 37 for 3x24 hours. The results showed the average inhibition zone activity against Pityrosporum ovale at a concentration of 75% of 19.17 mm statistically showed a significant difference. Formulation of shampoo preparations was carried out on red spinach leaf extract at a concentration of 15% with variations in the formula of Cocamide DEA and CMC-Na. The physical characteristics of the shampoo preparation include organoleeptic test, homogeneity, pH, viscosity, adhesion, spreadability and foam height. The results of testing the antifungal activity of shampoo preparations in formula 1 (17.5 mm); formula 2 (17.83 mm); and formula 3 (16.83 mm), based on statistical tests of antifungal shampoo preparations with a p-value (> 0.05) variations in the concentration of Cocamide DEA and CMC-Na have no significant effect on antifungal activity.

Abstract

Penggunaan minyak goreng secara berulang masih sering dilakukan oleh masyarakat karena keterbatasan pengetahuan mengenai dampaknya terhadap kesehatan. Minyak jelantah yang digunakan kembali sebagai media menggoreng berpotensi menghasilkan senyawa oksidatif yang berbahaya, sedangkan pembuangannya secara langsung dapat mencemari lingkungan. Di sisi lain Kelurahan Pedurungan Lor memiliki potensi berupa Tim Penggerak PKK yang aktif serta hasil urban farming berupa sereh yang dapat dimanfaatkan sebagai bahan tambahan produk sabun. Kegiatan pengabdian ini bertujuan meningkatkan pengetahuan dan keterampilan Tim Penggerak PKK Kelurahan Pedurungan Lor dalam mengolah minyak jelantah menjadi sabun ramah lingkungan berbasis sereh hasil urban farming. Metode yang digunakan meliputi observasi, penyuluhan, pelatihan, pendampingan, serta evaluasi menggunakan pretest dan posttest. Sebagai media pembelajaran berkelanjutan, disusun video edukasi mengenai pemurnian minyak jelantah, pembuatan minyak sereh, dan proses pembuatan sabun. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan peserta mengenai bahaya penggunaan minyak jelantah, pengelolaan limbah rumah tangga, serta keterampilan dalam memproduksi sabun ramah lingkungan. Program ini mengimplementasikan konsep Green Pharmacy dan Circular Economy melalui pemanfaatan limbah minyak jelantah dan sereh hasil urban farming menjadi produk non-pangan yang aman dan bernilai ekonomi. Kegiatan ini diharapkan dapat meningkatkan kesehatan masyarakat, mengurangi pencemaran lingkungan, serta mendukung pemberdayaan ekonomi keluarga berbasis potensi lokal.
