Abstract

SMEs face the problem of readiness and resilience in implementing digital transformation as part of the industrial revolution. Therefore, a process is needed to identify resilience factors that can increase the readiness of SMEs toward Industry 4.0. The industrial revolution 4.0 that emerged in recent years requires businesses and society to be ready to implement digital transformation. This study aims to identify the effects of resilience factors in the form of people, processes, and technology that influence the adoption of digital transformation in SMEs. The research object is SMEs in various sectors with a literature study approach to develop a conceptual framework and data collection using a questionnaire. Construct testing and data analysis used statistical methods from confirmatory factor analysis, while the data testing process used the Partial Least Square (PLS) method. The results of the study show that the resilient people (RPe) factor has a weak influence on international orientation (IO) but has a strong direct influence on digital transformation readiness (DT). The resilient process (RPo) and resilient technology (RTe) factors weakly influence DT but are significant on IO. Meanwhile, the IO factor has a strong influence on DT. As a mediator, IO has a weak role in mediating Rpe and DT but significantly mediates RPo, and RTe against DT. The results also show that an independent attribute of 65.9% influences DT, while IO has an independent attribute effect of 41%. The findings guide SMEs to pay attention to aspects of resilience in the work system and have a global orientation in business development plans to be more ready to adopt digital transformation.

Abstract

Sweet sorghum is the potential in Indonesia to be used as a fermentation medium for glutamic acid production. The sorghum plant resembles sugar cane which has sap in the stem. Sorghum is a plant with high sugar content and high biomass productivity. The high sugar content in sorghum sap is known from the total dissolved solids. The evaporation process on sorghum juice increases the sugar content and can inactivate microbial activity. Glutamic acid fermentation needs a substrate source derived from sugar for the growth of the producing microbes.  Therefore, this study aims to describe the sugar content in sorghum juice before and after the evaporation process so that it can be used as a substrate source for glutamic acid production. This research was carried out using the evaporation method of sorghum juice for 15 minutes at a temperature of 85 - 100 oC, so a concentrated sorghum sap was obtained. The analysis was pH, total dissolved solids (oBrix) using a refractometer, and reducing sugar content using the DNS method. The results obtained in this study indicated a significant increase in the quality and sugar content of sorghum sap with a pH of 4.81 ± 0.01 to 5.55 ± 0.03, total dissolved solids from 10.44 ± 0.09 to 34.80 ± 0.02 (oBrix), and reduced sugar content from 114.10 ± 0.45 to 271.74 ± 0.26 g/l. The sugar content allows sorghum juice to be used as raw material in industrial microbiology, especially for the production of glutamic acid.

Abstract

The Cocoa agroindustry requires future changes based on information technology that provide significant value benefits for organizations/companies (digital transformation). The experience during the pandemic required us to transform digitally. Cocoa agroindustry stakeholders such as cocoa farmers, farmer facilitators, and regulators have not been responsive to this, and the industry does not know what to do. The urgency of assessing the readiness for technology adoption in the cocoa agroindustry in Indonesia is urgently needed so that all stakeholders can feel the implementation of 4.0-based technology. What are the benefits of digital transformation to increase productivity, value creation, and social welfare in the industry?  This study aims to investigate and identify profiling of technology-based adoption, develop quantitative and qualitative models of TRI 2.0 and validate the assessment results. In this work, we take the case of agroindustry in Lampung province by involving cocoa agroindustry stakeholders. The technology readiness index 2.0 methodology provides a comprehensive framework with the result that the value of the Optimism variable is 1.05, the Innovativeness variable is 1.01, the Discomfort variable is 0.6, and the Insecurity variable is 0.75. The results of calculating the TRI 3.5 value, including the Intermediate Technology Readiness Index (Medium). The TRI value can be interpreted as Lampung cocoa agroindustry stakeholders in this case have have information and communications technology (ICT) potential and are not resistant to using new technology. Hopefully this will become a milestone for establishing a cocoa agroindustry community within the framework

Abstract

Moringa leaves (Moringa oleifera) are a "Superfood" food ingredient rich in protein, phenolics, amino acids, and unsaturated fatty acids that benefit human health. Consumption in fresh form is prevalent, but the last decade has been plentiful in dry preparations. Pulse Electric Field (PEF) is one of the important preliminary treatments in drying vegetables and fruits. Electroporation on Moringa leaves is applied to determine the effectiveness and efficiency of drying on the leaves. The study aimed to determine the effect of PEF treatment before drying on the kinetics of drying and the microstructure of Moringa leaves. PEF treatment is carried out at voltages of 1000V, 1500V, 2000V and without PEF as a control. The treatment during drying was observed at the level of moisture content and effective diffusivity on each of the PEF and control treatments. Experimental data were entered into seven mathematical models and evaluated through Lewis, Page, Modified Page, Logarithmic, Two-term, Wang and Singh, and Simple exponential models. The results of the evaluation of the drying model were selected as the best drying mathematical model on the Logarithmic model. The highest diffusivity effective value at PEF with a voltage of 2000V of 3.25 × 10−9 m2/s. In the microstructure changes of Moringa leaves, the preliminary PEF treatment was conducted using the scanning electron microscope (SEM) test. Moringa leaves with pretreatment PEF 2000V color analysis was lightness (L*), redness (a*), yellowness (b*), and ∆E values of 41.74±0.34a, -8.64±0.28c, 20.16±0.94a, 7.08±0.53c. The results of moringa leaves extract with pretreatment PEF 2000V were total phenols and IC50 values of 55.60±1.24d mg GAE/gram and 76.79±0.77a ppm. Implementing PEF preliminary treatment on drying is expected to accelerate the drying process and maintain a decrease in the quality of the final product of Moringa leaves.

Abstract

Telang (Clitoria ternatea) is a medicinal flower used in food and beverages. The beverages made from this flower are commonly available in Indonesia, but their properties have not been extensively investigated. Thus, this study aimed to determine the physicochemical properties of telang flower beverages, such as pH, vitamin C, anthocyanin, and hedonic level. The study employed a complete randomized factorial design. The weight of dried flowers and volume of lime juice were used as independent variables. The De Garmo effectiveness index selected the four best physicochemical characteristics of beverages. The addition of dried flower and lime juice resulted in a significant difference in anthocyanin, vitamin C, pH, and free radical inhibition activity. Four treatment beverages with good chemical qualities were chosen to be examined hedonically. The treatment with lime juice addition resulted in a significant difference in the hedonic level of color, sweetness, and acidity (p0.05). There was, however, no significant difference in the aroma produced in the beverages (p0.05). The best formulation of the telang flower beverage was based on hedonic analysis with a combination of 4.5 g of telang flower and 5 ml of lime juice, resulting in a beverage with less sugar and fewer calories.

Abstract

Sargassum plagyophyllum is a type of brown seaweed containing bioactive components including alkaloids, flavonoids, steroids/terpenoids, saponins and phenolics that have potential as antibacterial. This study aims to determine the bioactive components of the S. plagyophyllum extract fraction qualitatively and the antibacterial activity of the S. plagyophyllum fraction by agar diffusion method with wells. The method used in this research is an experiment by extracting and fractionating S. plagyophyllum. Parameter analysis consisted of analysis of bioactive components (alkaloids, flavonoids, steroids/terpenoids, saponins, phenolics) qualitatively and determining antibacterial activity in the S. plagyophyllum fraction against Staphylococcus aureus and Escherichia coli. The results showed that the bioactive components in the methanol extract of S. plagyophyllum contained flavonoids, steroids/terpenoids, saponins and phenolic compounds. The bioactive components in the ethyl acetate fraction contained alkaloids, flavonoids, steroids/terpenoids, saponins and phenolics. The n-hexane and butanol fractions contained steroids/terpenoids, and saponins. The extract fraction of S. plagyophyllum could inhibit the growth of antibacterial activity against S. aureus and E. coli bacteria. The ethyl acetate fraction was the best fraction inhibiting bacterial activity with the highest zone of inhibition compared to other fractions (n-Hexane and buthanol), namely 12.95 ± 0.64 mm for S. aureus bacteria and 10 ± 0.14 mm for E. coli bacteria.
