Abstract

This study aims to determine the effect of the concentration and duration of soaking of Sodium Metabisulfite on the quality of potato chips. The study was conducted with a factorial Complete Randomized Design (CRD), which consisted of two treatment factors. The first factor concentration of Sodium Metabisulfite with the code N, consists of 4 levels, namely: N0 = 0% (control), N1 = 1%, N2 = 2% and N3 = 3%. The second factor of the immersion time with the code L, consists of 4 levels, namely: L0 = 0 minutes (control), L1 = 30 minutes, L2 = 60 minutes and L3 = 90 minutes. Data analysis was performed with LSR (Least Significant Ranges) test.The results showed that the concentration of Sodium Metabisulfite had a significantly different effect (P <0.01) on water content, ash content, protein content, and fat content. The higher the concentration of Sodium Metabisulfite, the fat content decreases, while the water content, ash content, and protein content increase. Soaking time gave a very significant effect (P <0.01) on the water content, ash content, protein content, and fat content. The longer the immersion time, the higher water content, and fat content while protein content, fat content content decrease. The interaction between Sodium Metabisulfite Concentration and soaking time had a very significant effect (P <0.01) on ash content.

Abstract

This study aims to determine the effect of the comparison of the concentration of temulawak extract And sirih leaves on the manufacture of herbal drink. This research was conducted in the laboratory of processing and Management of Agricultural Products, Faculty of Agriculture, Santo Thomas Catholic University, North Sumatra, Medan. This research was conducted with a factorial Complete Randomized Design (CRD), which consisted of two treatment factors. The first factor Comparison of the concentration of Temulawak and Betel Leaf with a code (K), consists of 5 levels, namely: K0 = Temulawak: sirih leaves = 100%: 0%, K1 = Temulawak: sirih leaves = 80%: 20%, K2 = Temulawak: sirih leaves = 70%: 30%, K3 = Temulawak: sirih leaves = 60%: 40%, K4 = Temulawak: sirih leaves = 50%: 50%. The second factor is the comparison of storage duration with a code (L), consisting of 4 levels, namely: L1 = 1 Week, L2 = 2 Weeks, L3 = 3 Weeks, L4 = 4 Weeks.

Abstract

Andaliman  is  typical spice plant in North Sumatra, has benefits as antimicrobial and antioxidant. Tempeh is a protein source food, has short shelf life, so the tempeh processing technology is needed to create another product with  longer shelf life and increase its added value. One of them is by processing tempeh into nugget. The purpose of this study was to determine the shelf life of tempeh nugget added with andaliman fruit extract as  natural preservative and to determine which concentration was the most optimal in extending the shelf life of tempeh nugget. This study used  completely randomized design with two factors. Factor I was the concentration of andaliman extract (0%, 0.1%, 0.25%, 0.5%) and factor II was the storage time (0 day, 7 days, 14 days, 21 days). The parameters analyzed were total microbial, water content, and aroma organoleptic test. The results showed that the addition of 0.5% andaliman extract and 21 days storage time obtained the lowest amount of microbes, the lowest water content was obtained at 0% andaliman extract and 21 days storage time treatment, while the highest aroma organoleptic test was obtained at adding 0.5% andaliman extracts. This is due to the presence of antimicrobial in andaliman

Abstract

Omega 3 and 6 fatty acids are very good consumed to improve human health. For this reason, research is needed to determine the glyceride profile and identification of omega 3 and 6 fatty acids in fat molecules so that the potential of catfish oil as a source of omega 3 and 6 can be known. Catfish oil was extracted by the soxletation method. Fatty acid composition was analyzed by gas chromatography (GC-FID) which was previously esterified using BF3. The results showed that the composition of unsaturated fatty acids more than saturated fatty acids. Omega-3 fatty acids are found consisting of linolenic acid, eicosapentanoic acid (EPA) and docosahexanoic acid (DHA) and omega 6, namely linoleic acid. The comparison of omega 3 and omega 6 in catfish oil is still within the recommended comparison terms. Judging from the composition and position of catfish oil fatty acids which contain omega 3 and omega 6 fatty acids. Thus catfish oil has the potential as a source of omega 3 and 6 from one of the freshwater fish that are consumed by many people.

Abstract

This study aims to determine the effect of packaging types and storage duration on the quality of andaliman powder. The study was conducted at the Laboratory of Processing and Management of Agricultural Products, Agricultural Product Technology Study Program, Faculty of Agriculture, Catholic University of St. Thomas Medan. This research was conducted using Factorial Complete Random Design method. The first factor is packaging with a password (K), consisting of 4 types, namely: K1 is Glass bottle, K2 is Plastic bottle, K3 is Flip plastic and K4 is Paper. The second factor is the storage time with L code which consists of four levels, namely: L0 is 0 weeks, L1 is 2 weeks, L2 is 4 weeks and L3 is 6 weeks. The results showed that the type of packaging had a very significant effect on water content, total acid, oleoresin content and organoleptic value, but it was not significant for ash content. The highest water content, ash content and total acid were found in paper plastic packaging, while the lowest was in glass bottle packaging, while the highest oleoresin content and highest organoleptic value were found in glass bottle packaging, while the lowest was on paper packaging. Storage time has a very significant effect on water content, total acid, oleoresin content and organoleptic value, but not significant to ash content. The longer the storage, the moisture content, ash content and total acid content increase, while the oleoresin content and organoleptic values decrease. The interaction between the type of packaging and storage duration gave no significant effect on water content, ash content, total acid, oleoresin content and organoleptic value. The best quality of andaliman powder is obtained in the type of glass bottles and plastic bottles which can be seen from the water content, oleoresin content and organoleptic value.
