Abstract

Mayonnaise is an emulsion product consisting of oil, water and other ingredients which affect its stability. Improving the stability of mayonnaise can be done by using emulsifiers and stabilizers. This study aims to determine the type and concentration of the right emulsifier to produce a stable red fruit oil mayonnaise and to analyze the physical properties, total carotenoids, and organoleptic properties of the red fruit oil mayonnaise. In this study, degummed red fruit oil was used because the impurity components (gum and phospholipids) had been removed. The experimental design used in this study was a completely randomized design (RAL) with four different treatments of emulsifier, namely Gelatin 3.5% (M1), Gelatin: Lecithin = 3.0%: 0.5% (M2), Gelatin: Gum Arabic = 2.0%: 1.5% (M3), and Gelatin: Gum Arabic: Lecithin = 1.5%: 1.5%: 0.5% (M4) with three replications for each treatment. The results showed that the degummed red fruit oil mayonnaise of the four formulas produced varied in color from red, pink, orange, and dark orange, had a distinctive aroma of mayonnaise and a sour taste of mayonnaise (pH 4.31-5.20), had a thick texture (viscosity 220-297 d.Pas) with a total carotenoid content ranging from 3170.9-3410.1 ppm. The organoleptic properties (level of preference) of the four mayonnaise formulas produced include color having a score of 5.12-5.88 (like moderately), aroma with a score of 4.48-5.28 (neutral - like moderately), the texture of 5.00-5.40 (like moderately - like), taste ranges from 4.72-5.12 (neutral - like moderately), and the overall rating ranges from 5.08-5.64 (like moderately-like). Formula M1 (gelatin) and M3 (a combination of gelatin and gum arabic) can produce stable mayonnaise compared to other formulas.

Abstract

The development of oil palm plantations in Bengkulu Province has increased rapidly yearly. An increase also occurred in the CPO production sector. In 2021 the Bengkulu Province's CPO production rose to 30,052 tons of CPO from the total production in 2020 of 1,063,404 tons of CPO. PT X is a CPO production industry with a 30 tons/hour production capacity of FFB located in Bengkulu Province. PT X’s activities, from oil palm cultivation, fertilization and garden maintenance, industrial processing, waste treatment, and others, impact the environment and increase emissions. This research aims to evaluate the potential environmental impact of 1 tonne of CPO production. The method used is a life cycle assessment (LCA) with three impact categories: greenhouse gas (GHG) emission, acidification, and eutrophication. The boundary of the LCA study is cradle-to-gate, which includes the oil palm plantation subsystem and the industrial CPO production process subsystem. Based on the LCA results, the environmental impact of GHG, acidification, and eutrophication of 1 tonne of CPO production is 559.9 kg-CO2eq/tonne-CPO; 2.04 kg-SO2eq/tonne-CPO, and 0,96 kg-PO43-eq/tonne-CPO. GHG emission is the most significant impact resulting from the CPO production life cycle. Alternative recommendations for improvement to reduce the impact of replacing NPK fertilizer 12:12:17 with organic fertilizer EFB and using electricity from POME biogas (methane capture).

Abstract

Maintenance of production machines is the key to success for increasing the efficiency of production machines. The value of OEE (overall Equipment Effectiveness) is an important indicator of the level of effectiveness of production machines. The grinding machine at the cocoa powder company PT ABC Sidoarjo is a production machine that is considered to have the greatest contribution to achieving OEE values. However, up to now, the machine maintenance is only corrective so it has the potential to harm the company. The purpose of this study is to determine the effectiveness of the grinding machine and formulate recommendations for improvement. The method used is the six big losses analysis technique to identify the dominant type of loss, and the FTA (Fault Tree Analysis) technique to determine the root cause. The results of the analysis show that the OEE value of the grinding machine is only 45% (low). The types of losses that contributed greatly to these conditions were reduced speed losses by 41% and were categorized as bad. This is due to the absence of regular replacement of the grinding machine blades so that their performance is less stable. In addition, the values of idling and minor stoppages and set up and adjustment losses are also categorized as bad because of the frequent occurrence of wasted processing time. Only rework losses are categorized as good. A low OEE value indicates that the machine is still not working effectively. Recommendations for improvements that can be done are performing independent maintenance, forming a competent small group, arranging planned maintenance for replacing machine blades and installing vibrators on peripheral pipes

Abstract

Gelatin is a material produced from the partial hydrolysis of collagen sourced from the skin and bones of farm animals such as cows and pigs. Gelatin has been used for coatings because it has high permeability and dissolves in warm conditions, so the matrix cross-links are strong. The red snapper fillet processing industry produces 11.2-15% of waste, such as bone which has not been utilized optimally. The objective of this study was to determine the characterization of red snapper bone gelatin as a source of halal gelatin and measure its ability as a coating material for β-carotene pigment microencapsulation. Results showed the characteristics of red snapper bone gelatin with a yield of 10.71%, water content of 9.63%, protein content of 34.06%, ash content of 7.62%, gelatin fat content of 0.28%, and color intensity (L: 62.6). ; a+: 13.3 and b+: 30). The obtained halal gelatin was applied as a coating material for β-carotene pigment microencapsulation through the foam-mat method. It resulted in encapsulation with a yield of 16.75%, water content 9.25%, total carotenoid content 145.49 mg/g, surface carotenoid content 2.04%, solubility 78%, encapsulation efficiency 98.22%, color intensity (L: 50; a+: 29.9 and b+: 14.6), the particle size of 1004.04 μm and irregular shape.

Abstract

Jenang ayas is ethnic food from Gresik, East Java, Indonesia. Recently, jenang ayas are still packaged using improvised packaging, and the information conveyed regarding the product is still lacking. Even though the label information on the packaging can attract consumers' attention in making purchases, packaging will not only serve to protect the product but also as a means of promotion to increase the selling value of the product and influence the customer purchase decision. Therefore, this study aimed to examine the influence of the jenang ayas label and packaging that affect the customer purchase decision. A quantitative method with a descriptive approach was adopted following 179 responses to the online questionnaire. The finding revealed that the independent variables (label and packaging of jenang ayas) positively affected the dependent variable (customer purchase decision) both partially and simultaneously. The influence of food labels was greater than the packaging, with a value of 0.200 compared to 0.119. Label information, especially the expiration date, becomes an important factor in the jenang ayas product based on consumer choice. This study result provides useful insight into strategies for producing jenang ayas as Gresik food souvenir products in the Asian business.

Abstract

Belacan depik is one of the fermented products made from depik fish (Rasbora tawarensis). Fermented fish products often involve lactic acid bacteria (LAB) in the production process, but scientific studies on indigenous microorganisms, including LAB, have not been reported. This study aims to characterize and identify LAB originating from depik belacan, especially those with proteolytic activity. This research is exploratory laboratory research, consisting of making depik belacan, isolation and characterization of LAB, proteolytic LAB screening, and molecular identification of LAB. Three pure isolates suspected of LAB were obtained with different colonies, namely B1, B2, and B3. The three isolates had varied morphological and biochemical characteristics. Only two isolates were confirmed as LAB with positive and negative catalase and Gram test results. Of the two LAB isolates, only isolate (B1) was able to break down protein, so this isolate was a potential starter in the depik fish fermentation. Isolate B1 was identified molecularly as Enterococcus faecium strain DT-2 with a homology of 98.18% and Query Cover 100%. This isolate needs to be further confirmed for its ability as a potential starter in improving the quality of fermented depik fish.
