Abstract

A capillary electrophoretic (CE) analysis with ultra-violet (UV) detection was performed for further separation of low-molecular-mass (LMM) calcium species in phloem sap of Ricinus communis L. Two different background electrolytes (BGE) were used for the separation; these are (1) hydrogen phosphate/dihydrogen phosphate buffer containing cetyltrimethylammonium bromide (CTAB) as an electro-osmotic flow (EOF) modifier, and (2) boric acid buffer containing CTAB. Various parameters affecting the analysis, including the composition and pH of the BGE were systematically studied. The sensitivity, resolution, baseline noise, migration time of the species peaks, and reproducibility of the method were evaluated under optimised condition. At least 13 UV-active species were optimally separated within about ten minutes. The optimised measurement condition was also achieved using 10 mM hydrogen phosphate/10 mM dihydrogen phosphate containing 0.5 mM CTAB at pH 8.0 as BGE, and by applying voltage of ‑20 kV and temperature of 14°C. Evidently, the analytical method was successfully used for the separation of LMM calcium species in phloem sap of R. communis L.

Abstract

Yayasan Rumpun Nurani (YRN) merupakan sebuah organisasi nirlaba yang berjuang mengembangkan dan menguatkan sumber daya manusia melalui pendidikan, sosial, dakwah dan ekonomi. Salah satu visi misi YRN yaitu meningkatkan kesejahteraan umat yang diemban oleh Departemen Ekonomi. Departemen Ekonomi memiliki kelompok dampingan ibu tunggal dan ibu penopang ekonomi keluarga bernama Komunitas Ibu Pilihan (KIP). Ibu tunggal yang belum memiliki kesadaran berkegiatan ekonomi serta ibu penopang ekonomi keluarga berbasis UKM (Usaha Kecil dan Menengah) yang diharapkan mampu menghidupi dan mencukupi ekonomi keluarga merupakan tantangan tersendiri bagi YRN. Selanjutnya misi peningkatan kesejahteraan ekonomi umat diwujudkan dengan menggerakkan wadah penjualan produk berkualitas dari komunitas keluarga YRN dan KIP di bawah naungan Nunshop. Potensi Nunshop dalam menggerakkan ekonomi cukup besar. Produk-produk yang dijual – baik makanan maupun non makanan sangat berkualitas. Hanya saja, saat ini volume penjualan Nunshop masih terbilang kecil. Ketersediaan produk berkualitas sesuai konsep sehat yang diusung oleh Nunshop masih minim. Keterbatasan sumber daya manusia (produksi, marketing dan keuangan) menjadi kendala. Kondisi pandemik yang menyebabkan perubahan pemasaran berbasis online dan teknologi juga menjadi masalah. Hal ini disebabkan karena terbatasnya SDM (para ibu) yang melek teknologi. Berdasarkan permasalahan tersebut diatas diperlukan upaya pendampingan dalam hal peningkatan motivasi ber-UKM, peningkatan skill dan kualitas produksi pada komunitas serta pendampingan pemasaran produk berbasis teknologi. Hal ini dilakukan sebagai upaya peningkatan ekonomi ummat. Solusi yang diterapkan yaitu : (1) Peningkatan motivasi dan skill produk berkualitas berbahan alami, (2) Pendampingan pemasaran produk berbasis teknologi, dan (3) Peningkatan penjualan produk. Kegiatan pengabdian masyarakat yang dilakukan oleh UII bekerjasama dengan YRN telah berhasil memberikan motivasi ber-UKM serta meningkatkan jumlah produk. Program dan kegiatan ini dapat direkomendasikan menjadi program wilayah pemerintah Yogyakarta maupun nasional dalam pemberdayaan ibu tunggal dan ibu penopang ekonomi keluarga menjadi ibu yang tangguh, produktif serta melek teknologi dalam rangka penguatan ketahanan keluarga bangsa Indonesia.

Abstract

This research had been carried out on the formulation of guava leaf extract nanoemulsion as an active ingredient of antioxidant serum. The steps of this research include: (1) extraction by maceration; (2) Characterization and identification of extracts include phytochemical test, DPPH test, shear reagent test, and identification of compounds using LC-MS/MS; (2) formulation of nanoemulsion using Self-Nanoemulsifying Drug Delivery System (SNEDDS) method; (4) Nanoemulsion testing: stability test, antioxidant activity test using DPPH method, and irritation test, (5) nanoemulsion characterization which includes particle size, transmittance, pH, and viscosity. The results showed that: (1) the extract yields of the maceration method were 15,048%; (2) antioxidant compounds in Guava leaf extract were Candidate Mass C35H42O9, Candidate Mass C26H48O15, Candidate Mass C34H40O9, quercetin dan quercetin-3-O-α-L- arabinopyranoside; The IC50 of the macerated extract were 59,771 ± 1,357 ppm; (3) Nanoemulsions were made in 3 formulas (0.5; 1; and 1,5 g) with fixed variables of capryol 90, tween 20, and PEG 400 (1,5; 2,5; and 1); (4) stability test showed that only F1 was stable; the IC50 value of nanoemulsion is 509,039 ppm; and the F1 irritation test showed no erythema and edema; (5) The particle size of F1 was 168,2 nm with a transmittance value of 96,10%, a pH of 5,45, and a viscosity of 73,88 cP. So that the preparation of guava leaf extract nanoemulsion is not recommended as an active ingredient for making antioxidant serum. Keywords : Guava Leaf, Nanoemulsion, Antioxidant, Serum, SNEDDS
