Abstract

Chili is a vegetable as well as a kitchen spice that is almost always present in everyday food. One of the types of chili that has many benefits and nutritional content that is useful for the body is paprika (Capsicum annuum L. var Grossum). Chili peppers are rich in vitamin C even higher content than oranges. Vitamin C content in paprika was determined by UV-Visible spectrophotometric method. Analysis with UV-Vis spectrophotometer was carried out for various reasons, including simpler, more specific, more accurate and more precise operating principles which were developed and validated mainly for simultaneous and more specific evaluation to determine vitamin C levels. green, yellow and red. The results showed that the highest vitamin C levels were in red chili peppers, the value of vitamin C levels in green peppers was 11.67 mg/100 g, yellow peppers were 19.15 mg/100 g, and red peppers were 29,96 mg/100 g.

Abstract

Curcuma spp. consists of several species including temulawak (C. xanthorriza), turmeric (C. domestica), white ginger (C. zedoaria), and black ginger (C. aeruginosa). Likewise, it is known that the bioactive compound of turmeric rhizome is ascorbic acid (vitamin C). There are several methods developed to determine vitamin C levels, one of which is the UV-Vis spectrophotometry method. The research design used was descriptive experimental with the aim of knowing the levels of vitamin C in some Curcuma spp. growing in the Garut, Indonesia. This research uses UV-Vis Spectrophotometry method. From the results of this study, it has been reported that Curcuma xanthorriza has the highest levels of vitamin C compared to the others, namely the levels obtained are 0.720 mg/100 g.

Abstract

Milk as one of the results of livestock commodities is a food ingredient that is a source of nutrition or animal protein substances. Whole cow's milk must contain at least 3.25% of milk fat and 8.25% of nonfat milk solids. In this study, qualitative analysis of raw cow's milk samples for the determination of protein content was carried out using the biuret method and quantitative analysis using the Kjeldahl method. From the results of the biuret examination, a purple solution was obtained which showed a positive result containing protein. Quantitative results using the Kjeldahl method are NaOH with oxalic acid titration until the solution becomes a clear pink color. The average result obtained from the standardized titration of NaOH is 9.17. The result of analysis by quantitative titration is the reaction of HCl with NaOH and phenophthalein to form a clear pink color with an average of 9.3. The average yield of pure cow's milk protein content is 9.36%.

Abstract

Protein is a nitrogen containing substance that is an imfortant factor for body function. In most body tissues, protein is the larges component after water. Protein components are essential for the replacement of tissues, energy supplies, and versatile macromolecules in all biological processes as catalysts, transporting various other molecules such as oxygen, immune, and delivering nerve infusions. This research is conducted by qualitative and quantitative test. Qualitative test with biuret method while quantitative test with Kjeldahl method. White the aim to determine the protein levels in tilapia (Oreochromis niloticus) who was 1 month, 2 month, and 3 month districts Cikajang Garut. The results obtained by qualitative test with biuret method is characterized by the formation of violet to purple. In the quantitative test with Kjeldahl method, the results obtained in 1 month old tilapia are 1,419%, 2 months are 1,788%, 3 months is 2,15%.

Abstract

Formalin is a formaldehyde compound which contains approximately 30-40% in water. This study aims to determine the level of formalin content in salted fish sold in the Ciawitali market, Garut, West Java qualitatively with KMnO4 reagent and quantitatively using the acidia alkalimetry method. The results of the study using 14 random samples proved that there were 10 types of salted fish with different levels of formalin, ranging from 4.44% to 5.40%, while 4 types of salted fish negatively contained formalin.

Abstract

Pangi (Pangium edule Reinw.) or picung thrives in most of Southeast Asia, including Indonesia. Most of the people of Cisewu, Garut Regency, West Java consume picung seeds as food and as a complement to rice. Picung seeds contain cyanide, which has the potential to cause poisoning and even death if consumed in excess. In this study, cyanide analysis was carried out quantitatively using UV-Vis spectrophotometry and qualitatively using pictured paper. The results showed that 6 picung seeds from different trees were all positive for cyanide, indicated by the formation of a brick red color on picrat paper qualitatively, while the results of quantitative analysis of cyanide levels contained in picung seeds were 175 ppm.

Abstract

Worm infection caused by the Soil Transmitted Helminth (STH) are one of health problem in indonesia, as in vegetable farmers. Worm that are transmitted through the Soil are Ascaris lumbricoides, Trichuris trichiura, and Hookworms (Necator americanus and Ancylostoma duodenale). The purpose of this study was to determine the presence or absence of Soil Transmitted Helminth (STH) egs in vegetable farmer of Kartama Pekanbaru. This study used a cross-sectional design with the sedimentation method. Microscopic observation of 27 sample showed that STH eggs were not found in both faeces and nails samples. The examination method used was sedimentation method the population in this study were farmers in Kartama Pekanbaru who did hot use gloves or footwear during gardering.
