Abstract

Pisang nangka (Musa paradisiaca formatypica) is a type of banana that is consumed in processed form. One way of processing pisang nangka (Musa paradisiaca formatypica) is making it into pisang nangka jam. This product is in the form of paste which is processed by cooking pisang nangka pulp added with sugar and citric acid. The purpose of this study is to find out the effect of sugar and citric acid concentrations on several characteristics resulted from pisang nangka jam. And the aim is to determine the right sugar and citric acid, so it can produce pisang nangka jam with good characteristics. The experimental design used in this study is randomized block design (RBD) with a factorial pattern, each factor consisting of 5 levels and 3 levels, repeated 3 times. The first factor is sugar concentration (g) consisting of 5 levels, namely: g1 = 57.5%, g2 = 60.0%, g3 = 62.5%, g4 = 65.0%, g5 = 67.5%. The second factor is citric acid concentration (S) which consists of 3 levels, namely: s1 = 0.25%, s2 = 0.30%, s3 = 0.35%. Observation is conducted on sucrose content, water content, pectin content, and organoleptic assessments of aroma, spreadability, taste, color, and overall acceptance.

Abstract

Coconut (Cocos nucifera) has a strategic role for the people of Indonesia, considering that its product is one of the nine staples of society, namely coconut oil. One type of coconut oil that is beneficial for health and cosmetics is virgin coconut oil. Research on virgin coconut oil has been carried out from April to May 2022 at the Chemical and Processing Laboratory of the Faculty of Agriculture, Ma'soem University. The experimental treatments consisted of heating periods: A (3 minutes), B (4 minutes), C (5 minutes), D (6 minutes), E (7 minutes) and F (8 minutes). Each treatment tried was repeated 4 times. The method used is an experimental method using a completely randomized design (CRD) with Duncan's multiple range test statistic at a 5 percent level of significance. The results showed that the heating period of 6 minutes produced the best characteristics of virgin coconut oil. This determination is based on the content of free fatty acids, water content, color (very clear), preferred taste and aroma.
