Abstract

Fresh milk in Boyolali Regency is currently unable to meet the demand of the processing industry because the quantity is limited and the quality is below the standard. The large number of activities at each tier and the long supply chain flow for fresh milk have the potential to cause a decrease in quality and quantity, making it vulnerable to risk. Therefore, this research aimed to analyze risk management in supply chain and provide mitigation proposals. Data were collected by in-depth interviews with 51 respondents using purposive and snowball sampling techniques. The variables examined include supply chain flow of fresh milk, risks at each tier, causes and impacts of risks, as well as likelihood, severity, and capacity to manage risk. Data processing used ISO 31000:2018 and the Rapid Agricultural Supply Chain Risk Assessment (RapAgRisk) method to assess risk vulnerability. The results showed that in Boyolali Regency, fresh milk supply chain consists of four tiers, namely farmers, as well as milk couriers, collectors, and processors, comprising processing industry and street vendors. Mitigation proposals were given for nine risks in the categories of high, moderate, and low vulnerability. These risks include high animal feed prices, low forage availability, cows being attacked by foot and mouth disease (FMD), adulteration of fresh milk, the amount of fresh milk received by couriers and collectors fluctuating, rejection, sudden demand, and excess stock of fresh milk. Subsequently, risk mitigation proposals were provided to maintain quality and increase fresh milk production.

Abstract

Potato (Solanum tuberosum L.) plant is widely favored due to its versatility in various processed products, but perishable. This study aimed to determine the effect of chitosan coating and storage at various temperatures on the physiological and chemical characteristics of potato tubers. This research used 2 variables, namely the concentration of chitosan (0, 1, 1.5 and 2%) and storage temperatures of 0, 10 and 25°C. The parameters observed included tuber skin color, weight loss, hardness, the thickness of the chitosan layer and tissue penetration, oxygen levels, water content, starch degradation, reduced sugar content, and sprouting amount. Furthermore, data were analyzed using the Analysis of Variance (ANOVA) test. The results showed the effect of chitosan coating and storage temperature on weight loss, color, oxygen level, hardness, water content, starch degradation, and reduced sugar content in potato tubers during storage. The most effective treatment was 1.5% chitosan coating combined with a storage temperature of 10°C.

Abstract

Root system is recognized to play a crucial role in enhancing plant tolerance and stability during drought conditions. Therefore, this study aimed to assess safflower (Carthamus tinctorius L.) genotypes under various irrigation regimes and explore the relationship between root traits and yield. A two-year factorial experiment was conducted with three spring safflower genotypes, namely Parnian, Goldasht, and Kazak under two irrigation regimes, including full and deficit. Irrigation treatments maintained residual moisture levels at 60% and 20% of available water. Root traits such as biomass (RB), length (RL), diameter (RD), dry weight (RDW), and root length density (RLD) were measured. Additionally, seed yield (SY), yield components, and oil content (OC) were assessed in all treatments. The results showed that drought stress reduced safflower RB and RL, but Kazak genotype had a significant increase in RDW (48%) and RL (12%) under deficit irrigation. Root biomass distribution and RLD varied among genotypes across soil layers. Parnian and Goldasht genotypes had the highest root biomass at 30 cm depth with full irrigation, while Kazak showed the highest values at 60-90 cm depth under deficit irrigation. Drought stress significantly reduced safflower SY by 71% and Kazak genotype showed the highest SY under deficit irrigation, suggesting better performance stability. SY had a strong positive correlation with RDW (0.57) and RD (0.84), indicating a significant relationship. Furthermore, SY was significantly correlated with RLD at depths of 60-90cm (0.72-0.68). These results suggested that root traits such as RDW, RD, and RLD in deeper soil layers were crucial for breeding programs aiming to develop drought-tolerant genotypes.

Abstract

Phaseolus vulgaris L, known as red bean, is a staple food in Indonesia. The temperature sensitivity of red bean limits the applications despite the high starch content. Therefore, this research aims to analyze the effects of heat-moisture treatment (HMT) on the properties of red bean starch, focusing on the functional and morphological characteristics. The effects of HMT (4, 5, and 6 hours at 110°C) were elevated on fresh and dried red bean starch using Completely Randomized Design. The results show that significant alterations were observed in starch properties due to HMT. Water absorption capacity (WAC) varied with HMT duration and fresh bean starch peaked at 4 hours (198.0 ± 0.1%) before declining at 6 hours (159.5 ± 0.7%). In contrast, dried bean starch showed a decrease from the native capacity of 223.5 ± 5.0% to 176.5 ± 5.0% after 6 hours of HMT. Oil absorption capacity (OAC) also changed markedly and fresh bean starch increased from 68.0 ± 2.8% to 85.5 ± 0.7%. Similarly, dried beans increased from 67.0 ± 1.4% to 83.5 ± 0.7% since the effectiveness of HMT enhanced starch interaction with water and oil molecules. In fresh and dry beans, swelling power decreased and increased with prolonged HMT, reaching a peak at 4 hours (8.57 ± 0.15 g/g). However, solubility index decreased in both types following an increase in HMT duration. The morphology of starch granules transitioned from round or elliptical shapes to more polyhedral and irregular forms, reflecting substantial structural changes. In conclusion, HMT effectively modified the functional properties of red bean starch to offer potential benefits for application in food industry.

Abstract

Tobacco waste has the same bioactive compounds as tobacco leaves but with lower concentrations such as nicotine, phenolic compounds, aromatic substances, and solanesols. Utilization of tobacco waste that is not optimal can be processed to produce bioactive compounds that are beneficial to the surrounding environment. Tobacco waste can be processed into biopesticides containing nicotine and solanesol which function as antifungals and antioxidants. Tobacco waste was processed using the UAE maceration method using variables of temperature (40-600C), time (15-30 minutes), and type of solvent (acetone, methanol, and 96% ethanol). The results of UAE maceration were processed using Response Surface Methodology (RSM) data to determine optimal in yield, antifungal, and antioxidant activity tests. The study produced optimal values in UAE maceration, namely using a temperature of 52.470C, 29.86 minutes, and 96% ethanol solvent with a yield of 9.92%, 97.89% antifungal, and antioxidant activity (IC50) 16.75 ppm.

Abstract

The industry is intensively producing health product from herbal plants to combat free radicals and prevent the potential of cancer disease in the body. In Indonesia, Cemara Udang (Casuarina equisetifolia) leaves have been investigated as herbal tea product for antioxidant purposes as a free radical scavenger from various plants. This herbal tea requires significant attention during processing to produce a quality final product. Therefore, this research aimed to examine the effect of setting withering times of 14 and 16 hours, along with a drying temperature of 40 and 50 °C on cemara udang leaves. Product quality was evaluated based on the chemical components and nutritional characteristics of tea, such as moisture content, pH, antioxidant activity, total phenolic content, and vitamin C, as well as sensory aspects. The evaluation was carried out based on the degree of preference for color, aroma, and taste. Fresh cemara udang samples had 46.57% moisture content, pH 7.05, 131.53 µg/mL IC50 value, 1.53 mg/100 g total phenolic, and 43.46% vitamin C. Based on the degree of preference, color, flavor, and taste hedonic score had 3.11, 2.57, and 1.94 out of 7.00, respectively. Tea of cemara udang that was withered for 16 hours and dried at 50°C showed good quality stability with favorable sensory attributes. This varies significantly compared to the control, with 10.32% moisture content, pH 7.04, 137.94 µg/mL IC50 value, 1.2 mg/100 g total phenolic, and 29.26% vitamin C. Furthermore, color, flavor, and taste hedonic scores had 6.37, 6.03, and 6.27 out of 7.00, respectively.

Abstract

The working environment in Micro, Small, and Medium Enterprises (MSMEs) is considered less than ideal based on the Indonesian Minister of Health Regulation Number 70 of 2016 concerning Standards and Requirements for Industrial Working Environment, in relation to temperature, lighting, noise intensity, and humidity. Therefore, an analysis is necessary to improve MSMEs’ ability to create an ideal working environment. This study aimed to analyze and improve working environment ergonomics by focusing on the physical working environment, workers preferences and sensitivities, as well as work environment risks associated with various factors. The case study examined MSMEs in Klaten Regency, Central Java. The methods used included working environment observation, HIRARC (Hazard Identification, Risk Assessment, and Risk Control), Kansei engineering, and multiple linear regression (MLR). Specifically, HIRARC was used to assess risks, Kansei engineering to identify workers preferences and sensitivities, and MLR to determine correlations between variables. One of the risky working conditions was observed at the smoking and frying workstation, where the temperature reached 32.81˚C, exceeding the reference value of 31˚C. Lighting levels were recorded at 101.09 lux, below the recommended 200-500 lux. Noise levels measured 68.38 dB, within the acceptable limit of 85 dB, while humidity was 52.63% compared to the reference value of 51.36% ± 5.72%. HIRARC assessment classified the risk level at the smoking and frying workstation as medium to extreme. Furthermore, Kansei engineering identified key perception variables, namely dark vs. light, dirty vs. clean, unpleasant vs. pleasant, stuffy vs. cool, and hot vs. cold. The results showed working environment parameters significantly correlated with HIRARC and Kansei engineering variables, which consequently correlated with HIRARC.

Abstract

Lactic acid is often produced from lignocellulosic materials through various steps, including pretreatment, hydrolysis, and fermentation. Therefore, this study aims to evaluate the conversion of lactic acid from rice straw using simultaneous and separate hydrolysis and fermentation. The process was initiated with and without pretreatment using Ca(OH)2 at 85 °C for 16 hours, followed by hydrolysis using Trichoderma reesei PK1J2 and fermentation with Rhizopus oryzae AT3. Hydrolysis and fermentation were performed simultaneously and separately. The results showed that pretreatment could reduce lignin content, but this process was not needed because Trichoderma reesei PK1J2 degraded lignin during hydrolysis. In addition, fermentation conditions in this study could not support the production of lactic acid by Rhizopus oryzae AT3. Based on biomass growth during the treatment, simultaneous hydrolysis and fermentation (108 mg/g dry substrate) was better compared to separate hydrolysis and fermentation (104 mg/g dry substrate).
