Abstract

Sebagian besar ibu-ibu PKK di Karang Menjangan V Surabaya, merupakan ibu rumah tangga dan rata-rata masyarakat berpenghasilan rendah dan kebutuhan semakin meningkat dari tahun ke tahun, oleh karena itu ibu - ibu PKK disini memiliki program pengumpulan minyak jelantah untuk nantinya bisa di jual kembali sebagai tambahan penghasilan. Pengamatan di lapangan menunjukkan bahwa pemanfaatan kelapa beserta limbah minyak jelantah berbasis teknologi dapat meningkatkan nilai jualnya dengan mengetahui cara pembuatan sabun padat organik ini diharapkan remaja dan ibu – ibu rumah tangga di daerah tersebut dapat menerapkan dan nantinya juga dapat berwirausaha dengan ide sabun padat organik ini. Kegiatan terbagi menjadi dua tahap, tahap pertama diawali dengan penyuluhan pemanfaatan VCO untuk kosmetik salah satunya adalah sediaan sabun dan tahap kedua worksop pembuatan sabun padat organic.selama mengikuti kegiatan ini masyarakat sangat antusias.Melalui  pelatihan  pembuatan  dan  pengolahan VCO diharapkan  masyarakat karang menjangan V surabaya khususnya  para  ibu – ibu PKK dapat memahami cara pengolahan kelapa menjadi minyak kelapa, VCO dan pengolahan untuk meningkatkan nilai jual VCO  jika  dijadikan  sabun dan  diharapkan  dapat  meningkatkan  tingkat  perekonomian masyarakat.

Abstract

The degradation of Vitamin C in orange and tomato juice with sucrose addition and were storaged for 0, 30, and 60 minutes at room temperature were investigated. The level of vitamin C in juice was ensured by spectrophotometric method. The result indicated that vitamin C in sample with sucrose addition, decreased by about 0,41% (orange juice); 0,47% (tomato juice) after 30 minutes of storage; and 0,82% (orange juice); 1,19% (tomato juice) after 60 minutes of storage; while vitamin C in sample without sucrose addition, decreased by about 1,2% (orange juice); 2,12% (tomato juice) for 30 minutes of storage; and 2,45% (orange juice); 2,89% (tomato juice) for 60 minutes of storage. In conclusion, sugar addition and storage time could affect the degradation of vitamin C.

Abstract

Repeated use of cooking oil produces hazardous compounds such as free fatty acids, carbonyls, and peroxides. This study aims to examine the effectiveness of turmeric as a bio-adsorbent in reducing free fatty acid levels, peroxide numbers, and water content in used cooking oil, and determine the appropriate adsorption isotherm model. Turmeric is one of the biopharmaceutical plants whose availability is quite abundant in Indonesia. Adsorption was carried out with variations in adsorbent mass and contact time. The result showed that turmeric is effective in reducing free fatty acid levels, peroxide value, and water content with adsorption efficiency of up to 54.02, 48.78, and 42.89%, respectively. The adsorption isotherm analysis suggested that the adsorption of free fatty acids followed the Freundlich model rather than the Langmuir model. This study reveals that turmeric has the potential to be a viable bio-adsorbent for enhancing the quality of used cooking oil.

Abstract

Mango is a plant that is commonly cultivated and consumed in Indonesia. Mangoes are generally consumed directly, and some are made into processed products, one of which is wet candied. This processing aims to extend the shelf life of the fruit. The process of making wet candied is generally soaked with sodium metabisulfite as a preservative. This study aims to determine the effect of soaking time and sodium metabisulfite concentration on vitamin C levels in Manalagi candied mangoes. Vitamin C is an unstable compound and is easily oxidised during processing. Vitamin C content in Manalagi Candied mangoes was analysed by Iodometric titration method. The results of this study showed that the levels of vitamin C obtained from candied mangoes soaked in sodium metabisulfite for 30, 60, 90, 120, and 150 minutes were 115.3; 153.22; 184.49; 150.0; and 170.32 mg/L, respectively. The level of Vitamin C in candied manalagi mangoes soaked in 50; 100; 150; and 200 ppm sodium metabisulfite was 128; 136.8; 107.84; 123.68 mg/L, respectively. The results of the ANOVA statistical analysis have a Sig value more than 0,05 indicating that the soaking time of sodium metabisulfite and the concentration of sodium metabisulfite have no significant effect on vitamin C levels in Candied Manalagi Mango.
