Abstract

Coagulants are commonly used in rubber plantations to coagulate latex. This study aims to determine the effect of incubation time and dose of starfruit extract on coagulation speed, total solid content (TSC), and weight loss of the resulting coagulum. The study was carried out at the Sungei Putih Research Unit, Indonesian Rubber Research Institute in September – October 2023. A Completely Randomized Design (CRD) was applied with two treatments, namely, the incubation period for the extract (A) which consisted of three levels (0 days (A1), 2 days (A2), and 4 days (A3)) and the extract dose (B) consisting of three levels (3 ml (B1), 6 ml (B2), and 9 ml per 20 ml latex (B3)). Each treatment combination was repeated three times. The results indicated that the degree of acidity (pH) of starfruit extract without incubation was around 2.8. After incubation for 2 days, the pH decreased to 2.7, and after 4 days to pH 2.5. The fastest coagulation was obtained in treatment A3B3 for 2.03 minutes after mixing, while the longest was in treatment A1B1 for 7.07 minutes. The highest coagulum TSC was obtained in the A3B1 treatment at 50.30%, while the lowest was in the A2B3 treatment at 27.47%. The highest level of weight loss was found in the A2B2 treatment at 36.80%, while the lowest was in the A3B3 treatment at 23.01%. The use of high doses of starfruit extract can coagulate latex in a short time with low weight loss; thus, it can be used as an organic coagulant.

Abstract

The level of production and consumption of chicken eggs in Indonesia continues to increase. This condition will be in line with the amount of eggshell waste that has not been utilized properly. Egg shells are rich in calcium and have the potential to be used as a calcium source in the form of powder or flour through fortification into various foods. As for right now, there is no literature study available that addresses the impact of eggshell powder addition as a calcium fortification affects the characteristics and level of acceptance of various food products This literature review used the scoping review method, and the articles used in this review were obtained through searches using Google Scholar, ResearchGate, and PubMed. The results of this literature review show that eggshell powder is suitable to be added to food products as a source of calcium. Adding eggshell powder can greatly increase the calcium content of a variety of foods. Aroma, taste, and texture are the organoleptic characteristics that are mainly impacted by the addition of eggshell powder. The addition of eggshell powder is generally contradictory to the degree of liking and acceptability of the product. The degree of product acceptance and liking tends to decrease as eggshell powder concentration increases. Thus, it is imperative to perform suitable calculations concerning the highest concentration of eggshell powder applied to preserve the food product's unique qualities and attributes while preventing a decline in the product's degree of acceptance or liking.

Abstract

Home Industry products and Micro, Small and Medium Enterprises (MSMEs) in the form of traditional foods are widely developed in Sukoharjo Regency. Traditional food karak crackers are one of the products favored by the people of Central Java, especially Sukoharjo Regency. Karak crackers are a food that is much loved by the community because it tastes savory, cheap and can be used for side dishes and snacks. The main ingredient in making karak crackers is poor quality rice or rice groats with added salt and bleng. Bleng is alleged to contain borax, which is harmful when it enters the human digestive system. This study aims to determine the presence of borax contained in karak crackers produced by IRTs and MSMEs in Bulu Subdistrict and to select alternative ingredients to replace bleng (borax). This research was conducted with 2 methods, namely survey and evaluation, in the survey method to determine the sample using stratified purposive sampling with 3 levels. After the karak cracker samples were collected, the presence of borax was tested using turmeric extract. The results obtained stated that all samples from IRTs and MSMEs contained borax.

Abstract

Tomato sauce is a food product made in the form of tomato paste. Making tomato sauce requires a thickener. The thickener commonly used in making tomato sauce is CMC (Carboxymethyl Cellulose) which does not contain elements that are beneficial to health. One natural thickening agent that has the potential to be developed is breadfruit starch. This research aims to determine the effect of adding breadfruit starch on the characteristics of tomato sauce. The research began with making breadfruit starch, then making tomato sauce according to the treatment and continued with product analysis. This study used a simple complete random design with one factor, namely S(0.5) as much as 2.5 grams of breadfruit starch, S(1.0) as much as 5 grams of breadfruit starch, S(1.5) as much as 7.5 grams of breadfruit starch, SM (0 grams added breadfruit starch/using 5 grams of cornstarch), and SK (commercial tomato sauce). The data obtained were analyzed using One Way Anova and to determine whether there were differences in treatment, the Duncan Multiple Range Test (DMRT) was continued with a significance level of 5%. The results showed that the addition of breadfruit starch had a significant effect on water content S(1.5) with a value of 76.87%, degree of acidity/pH S(0.5) with a value of 4.01, total dissolved solids S(1.5 ) with a value of 27°Brix.

Abstract

Breadfruit is a fruit that grows widely in Indonesia. The use of breadfruit is still very limited, namely fried or boiled as a snack. Breadfruit has a high carbohydrate content, resulting in quite a lot of starch extraction. One way to increase the use of breadfruit is to process it into breadfruit starch. Breadfruit starch has a high amylose and amylopectin content so it can be used as a chewing agent in cendol production. The aim of this research is to obtain the ratio of breadfruit starch in making cendol, by testing water content and total dissolved solids. The data obtained were analyzed using One Way Anova and to determine whether there were differences in treatment, it was continued with the Duncan Multiple Range Test (DMRT) with a significance level of 5%. The results of the research show that the correct ratio in making cendol to substitute breadfruit starch would be 25% rice flour and 75% breadfruit starch. The addition of breadfruit starch to making cendol has a significant effect on the water content of 81.37% -84.45%. The addition of breadfruit starch did not significantly differ from the total amount of dissolved solids with a value of 6.33-6.67 brix.

Abstract

Donuts are a type of bakery product made from high-protein wheat flour and have a distinctive shape, in the center is hollowed out like a ring. The purpose of this study was to determine the chemical and organoleptic characteristics of donuts with the addition of suweg flour and variations in yeast concentration that are most favored by consumers. This study used a factorial completely randomized design (CRD) with 2 factors, namely the ratio of wheat flour and suweg flour (90:10, 85:15, and 80:20) and variations in yeast concentration (2, 4, and 6%). The best donut formulation favored by panelists was the formulation of 85% wheat flour: 15% suweg flour and the addition of 4% yeast concentration, where the donuts have a liking value for color 3.96 (neutral), taste 3.48 (neutral), aroma 3.00 (neutral), texture 3.88 (neutral), and overall liking 3.80 (neutral), and have a moisture content of 19.75%, ash content 1.01%, fat content 28.00%, total protein content 8.13%, carbohydrate content 43.11%, and crude fiber content 6.32%. Therefore, based on the results of the study, the formulation chosen was the formulation of 85% wheat flour: 15% suweg flour and the addition of 4% yeast concentration.
