Abstract

Flakes are food products that have the shape of thin sheets, brownish yellow in color with a practical presentation. Flakes are easy to process and generally consumed for breakfast. Flakes that are rich in dietary fiber and protein can serve as a source of energy while also offering functional advantages. The objective of this study is to generate flakes with elevated levels of dietary fiber and protein by utilizing mocaf and yellow kepok banana bud flour. The use of mocaf flour in the manufacture of flakes intends to improve the fiber content, while the use of yellow kepok banana bud (YKBB) flour aims to boost the protein level. This research was conducted to determine the chemical characteristics of flakes with variations of mocaf flour and KBF. The chemical characteristics include moisture, ash, crude fiber, total protein, lipid, and carbohydrate content. This study used a completely randomised design (CRD) with 2 replications with a ratio of wheat flour, mocaf flour, and YKBB flour as much as the control (20g:0g:0g), F1 (10g:10g:0g), F2 (10g:2.5g:7.5g), F3 (10g:5g:5g) and F4 (10g:7.5g:2.5g). The results showed that the moisture content was 2.43–3.19% w.b., the ash content was 2.55–11.72% d.b., the crude fiber content was 2.17–8.40% d.b., the total protein content was 4.34–7.85% d.b., lipid content 2.46–3.17% d.b., and carbohydrate content was 76.91–87.98% d.b.

Abstract

Active packaging is packaging designed to extend shelf-life or to maintain or improve the quality of packaged food. The concept of active packaging is to add certain components to the packaged food system or the surrounding environment. Dodol is a perishable food because it has a high-water content. The deterioration typically manifests as the presence of microbial growth and rancidity on the dodol. To increase the shelf life and quality of dodol is by wrapping it with active packaging. This study aimed to determine the effect of using active packaging on the chemical properties (water content, peroxide number, and antioxidant activity) and total plate count (TPC) of dodol. Active packaging made from cassava starch with the addition of klutuk banana leaf extract (KBLE) of the wulung variety as a source of antioxidant compounds is made by casting method. This research was conducted in two variables, namely the Wulung variation of KBLE concentration (0% and 20% w/v) and storage time (0; 5; 10; 15; 20; 25; and 30 days). The results of this study indicate that the active packaging (F2) applied to dodol has a significant effect (p<0.05) on the water content, peroxide value, antioxidant activity, and TPC values of dodol. Dodol packaged using active packaging after 30 days had lower water content, peroxide value, and TPC values than dodol packaged without KBLE. In addition, the value of antioxidant activity in dodol and active KBLE packaging obtained higher values (37.5% on days 30th) than packaging that was not given KBLE.

Abstract

This paper presents a control system design for a magnetic levitation system (Maglev) or MLS using sliding mode control (SMC). The MLS problem of levitating the object in the air will be solved using the controller. Inductors used in MLS make the system have nonlinear characteristics. Thus, a nonlinear controller is the most suitable control design for MLS. SMC is one of the nonlinear controllers with good robustness and can handle any model mismatch. Based on simulation results with a step as input reference, MLS provided good system performances: 0.0991s rise time, 0.1712s settling time, and 0.0159 overshoot. Moreover, a prominent tracking control for sine wave reference was also shown. Although the augmented system had a chattering effect on the control signal, the chattering control signal did not affect MLS performances.

Abstract

CV TSR is one of the industries that produces Etawa goat's milk with some processing carried out manually, especially in the drying process when milk is mixed with sugar and heated in the traditional way, because it does not involve a heating process with a machine so there will be a possibility of uneven heat, skill differences between workers can also cause the rate of evaporation from one pan to another is different. Therefore, it is necessary to carry out heavy observations in order to guarantee product quality and minimize non-conformance to the SOPs that have been determined, especially in the process of receiving raw materials up to the production process. In analyzing the data, the methods used are control charts and fishbone diagrams. The results show that 5 data experienced out of control in observations for 15 days using the batch system and the results of the fishbone diagram that human factors greatly influence the discrepancy in the final results of powdered Etawa goat milk production so it is necessary to pay attention and disseminate knowledge of SOPs in handling fresh goat milk as the main raw material.

Abstract

Biofilm is an alternative packaging for food products in the form of thin layers made from natural materials that are safe to use and for consumption. One of the materials used in the manufacture of biofilms is starch. However, starch-based biofilms have a weakness, namely their low water resistance. The addition of green cayenne pepper leaf extract is thought to improve the physicochemical properties as well as the potential to become antimicrobial for biofilms. The purpose of this study was to determine the effect of the addition of green cayenne leaf extract on the physicochemical and antimicrobial properties of cassava starch biofilm. The green cayenne leaf extract formulations used in this study were F0 (control), F1 (1 ml), F2 (1.5 ml), F3 (2 ml), F4 (2.5 ml) and F5 (3 ml) with 3 repetitions each. The results of this study indicate that the addition of green cayenne leaf extract has a significant effect on thickness (0.17-0.26 mm), tensile strength (2.25-5.87 Mpa), elongation (44.9-81.9 % ), solubility (23.1-27.6 %), water vapor permeability (5.20-9.23 g/m.s.kPa), moisture content (11.3-11.8 %) and microbial inhibition on F5 results in higher values ​​of F0 and F1.

Abstract

Lamtoro Gung seeds are low in fat content but rich in protein. Lamtoro Gung is often used as an alternative protein source. Lamtoro Gung is usually taken as a prepared meal containing grains and nuts. It is germinated and utilized in a variety of dishes, including the production of tempeh. However, nothing has been done to explain the textural profile of Lamtoro Gung tempeh, which is made by fermentation processes in various packaging materials such as plastic, banana leaves, and teak leaves. This study aims to evaluate the textural characteristics of Lamtoro Gung tempeh produced using different packaging materials and fermentation periods. This study contributes to understanding how packaging variations affect the texture of Lamtoro Gung tempeh. Tempeh made from teak leaf packaging and fermented for four days offered better texture profile hardness (195.38 N), cohesiveness (0.46), gumminess (81.57 N), and chewiness (54.99 N) higher than banana leaves; hardness (49.90 N), cohesiveness (0.29), gumminess (14.52 N), and chewiness (10.14 N) but similar to plastic; hardness (165.28 N), cohesiveness (0.45), gumminess (74.23 N), and chewiness (50.35 N). Therefore, packaging material impacts the texture profile of tempeh fermented from Lamtoro Gung seeds. Sensory evaluation of the tempeh would need to be investigated to check consumer acceptance of the product.

Abstract

The reduced quality of red chili can be attributed to moisture loss. To inhibit water vapor transfer, one effective method is using an edible coating. This study aims to determine the effects of sago starch and chitosan as coating materials in reducing chili deterioration during storage at room temperature. A one-factorial, completely randomized design was used, with variations in the ratios of sago starch to chitosan (76.19%:23.81%, 71.43%:28.57% and 66.67%:33.33%). The parameters tested included weight loss, hardness, color, and moisture content. Red chili storage was conducted at room temperature, with observations on days 1, 3, 6, 9, 12, and 15. The results indicated that the edible coating made from sago starch and chitosan significantly impacted the weight loss, hardness, color, and moisture content of the red chili. The best treatment for maintaining the physical and chemical properties of red chili during room temperature storage was the 66.67% sago starch and 33.33% chitosan formulation, which resulted in a weight loss of 46.99%, hardness of 35.01 N, color a* value of 30.60%, color b* value of 20.90%, brightness L* value of 26.11%, and moisture content of 67.92%.
