Abstract

AbstrakPenelitian ini dilakukan untuk mengetahui kadar kalsium serta zat besi dalam kangkung air dan kangkung darat. Dalam penelitian ini sampel yang dianalisis adalah Kangkung Air (Ipomoea aquatica forsk) Dan Kangkung Darat (Ipomoea reptans poir). Kemudian kadar zat besi diukur dengan spektrofotometri UV-Vis pada panjang gelombang 509 nm. Penetapan kadar kalsium di ukur dengan kromatografi ion pada 10 ppm, 20 ppm, dan 30 ppm. Hasil dari penelitian ini menunjukan bahwa kadar zat besi tertinggi terdapat pada kangkung air bagian batang yaitu 0,144 mg/kg yang berasal pasar Bastiong, sedangkan kadar zat besi terendah pada kangkung darat bagian daun yaitu 0,057 mg/kg yang berasal dari Ternate Selatan. Kadar kalsium tertinggi terdapat pada kangkung darat bagian batang yaitu 8,871 mg/kg yang berasal dari Ternate Selatan, sedangkan kadar kalsium terendah terdapat pada kangkung air bagian daun yaitu 0,821 mg/kg yang berasal dari Jatiland Mall.Kata Kunci: Ca, Fe, kangkung darat, kangkung air, kromatografi ion, spektofotometer UV-VisAbstractThis research was conducted to determine the levels of calcium and iron in water kale and land kale. In this study, the samples analyzed were water kale (Ipomoea aquatica forsk) and land kale (Ipomoea reptans forks. Then iron levels were measured using UV-Vis spectrophotometry at a wavelength of 509 nm. Determination of calcium levels was measured using ion chromatography at 10 ppm, 20 ppm and 30 ppm. The results of this research show that the highest iron content is found in the stem part of the water kale, namely 0.144 mg/kg which comes from the Bastiong market, while the lowest iron content is in the leaf part of the land water spinach, namely 0.057 mg/kg which comes from South Ternate. The highest calcium levels were found in the stem part of land kale, namely 8.871 mg/kg, which came from South Ternate, while the lowest calcium levels were found in the leaf part of water kale, namely 0.821 mg/kg, which came from Jatiland Mall.keyword: Ca, Fe, land kale, water kale, ion chromatography, UV-Vis spectrophotometer

The Method used is the phytoremediation method by utilizing water spinach plants. The analysis used is UVVis spectrophotometry, bioconcentration factor, translocation factor. The research results obtained the concentration (Fe) in well water before treatment amounted to 1.40 mg/L, after treatment with a variation of 10, 15, and 20 stalks respectively 1.29 mg/L, 0.95 mg/L, and 0.61 mg/L. Water spinach is able to absorb iron (Fe) levels in well water with the highest absorption occurring in the roots with the number of variations of 20 stalks amounting to 937.5 mg/kg. There is an influence after the phytoremediation treatment on the absorption of iron (Fe) levels in well water.

Abstract

Cooking oil is a basic need for everyday people, approximately 80% of the people of Ternate City use cooking oil repeatedly for cooking in order to save costs. The repeated use of used cooking oil or waste cooking oil with high heating produces free fatty acids, carbonyl compounds, peroxides, decreases the value and nutrition of fried foods, so that over time it has an impact on health. Efforts to process used cooking oil in the City of Ternate by saving costs but not endangering health really need to be carried out by using the typical North Maluku banana peel (Musa sp) as a natural adsorbent to purify used cooking oil. Starting from the preparation of tools and materials, the processing of banana peels, mixing the ingredients in the adsorbent, testing the levels of free fatty acids, determining the levels of free fatty acids and the characteristics of the clusters of banana peels using the Fourier Transform-Infra Red. In this study, the percentage reduction in free fatty acid levels was 0.833%, which was originally 1.882%. These results indicate that the refining of used cooking oil using banana peels is close to the Free Fatty Acid (FFA) value regulated in the Indonesian National Standard (SNI) of 0.3%. Keywords: Used cooking oil, peel of banana's mouth duck (Musa sp), refining.
