Abstract

Noodles are a food that all groups love. Many noodles sold in the community use natural dyes, although many still use synthetic dyes. This condition can be seen by the public starting to understand the importance of maintaining health, especially food coloring, so many noodles in circulation use natural coloring. Natural dyes are safe to use and have functional properties that are not available from artificial dyes, but have the weakness of being easily damaged during processing, especially at high temperatures. Generally, processed noodles use high temperatures in the process. Therefore, this research aims to identify the noodle processing process that causes the greatest damage to the color quality of the noodles produced. This research used a Completely Randomized Design with four treatments: boiling, steaming, steaming and drying, and steaming and frying. Noodle dough was used as a control in the treatment. This research used three replications. Observations were made on antioxidant activity, polyphenol, anthocyanin, betacyanin, and color quality. Based on this research, the noodle processing that provides the best colour quality is the steaming treatment with antioxidant activity of 21.69%, polyphenol content of 34.99 mg GAE/100 g, anthocyanin content of 40.72 mg/100, betacyanin content of 39.25 mg/100, and colour L* = 45.73, a* = 13.54 and b* = 9.86.

Abstract

This study aims to analyze the types of dominant contaminant molecules, identify the factors causing contamination, compare pesticide residue characteristics between regions, examine the relationship between residues and cultivation or processing practices, and formulate mitigation strategies for pesticide residues in cinnamon (Cinnamomum burmannii) commodities in Jambi and West Sumatra Provinces. The analysis revealed seven dominantly detected contaminant molecules, namely phenylphenol 2-, propamocarb, chlorpyrifos, fipronil, fipronil (sum), isoprocarb, and diethyl-m-toluamide (DEET), each with a detection frequency above five percent. These molecules are suspected to originate from pesticide applications, environmental pollution, and human activities. Statistical analysis using the Mann-Whitney U Test showed that 12 molecules had significantly higher residue levels in samples from West Sumatra compared to Jambi (p < 0.05), including ametryn, anthraquinone, carbofuran and its fractions, ethion, ethylene oxide, griseofulvin, nicotine, propamocarb, chlorpyrifos, DEET, and isoprocarb, indicating a clear regional difference. Jambi samples classified as high-grade had lower residues, reflecting that high quality can be achieved through sustainable farming practices such as integrated pest management and natural drying, rather than intensive chemical treatments. These findings suggest a negative correlation between visual quality and residue levels. Recommended mitigation strategies include the application of IPM, farmer education, post-harvest washing and drying, and environmental remediation. The 2021–2025 trend shows residue fluctuations peaking in 2023 before declining, highlighting the importance of regular monitoring. This research provides a scientific basis to support food safety, sustainable production, and enhance the export competitiveness of Indonesian cinnamon Keywords- pesticide residues; cinnamon; cinnamomum burmannii; Jambi; West Sumatra

Abstract

The use of swampland faces various challenges, such as flooded soil conditions, high acidity levels, and limited access to agricultural facilities and infrastructure. One of the solutions to overcome these challenges is the modernization of agricultural tools and machinery (alsintan), especially the use of hand tractors as an efficient soil tillage tool and in accordance with the characteristics of swampland. Tapus Village is one of the administrative areas located in Pampangan District, Ogan Komering Ilir Regency, South Sumatra Province. Tapus Village already has agricultural tools and machinery in the form of hand tractors that are quite adequate, but their use is still not optimal. The purpose of this study is to determine the role and strategy in optimizing hand tractor agricultural tools and machinery to support the management of swampland (OPLA) in Ogan Komering Ilir Regency in a more optimal and sustainable manner. In this study, methods were used in the form of literature study, gap analysis, SWOT (Strength, Weakness, Opportunity, and Threat) analysis, conducting needs and opportunities studies (KKP) and conducting observations and deep interviews with resource persons using questionnaires. The results of the study show that the optimization strategy of Alsintan hand tractor to support OPLA in Tapus Village can be carried out through the empowerment of farmers through training, socialization, and education on the use and maintenance of hand tractors, increasing the capacity of special operators, utilizing Alsintan hand tractors that are available, increasing UPJA and Alsintan workshops in Tapus Village. It is hoped that the results of this research can support the sustainability of the implementation of the strategy so that it can be carried out efficiently and effectively.

Abstract

The use of coconuts produces agricultural waste such as coconut fiber. Immature coconut fiber and mature coconut fiber are lignocellulosic materials that can still be utilized, one of which is by processing them into furfural. Furfural is a clear liquid with a distinctive almond aroma that is widely used as an additive by the chemical industry. The purpose of this study was to determine the effect of the level of coconut fiber maturity with various catalyst concentrations and differences in reaction time on furfural yield. This study used two samples: mature coconut fiber and immature coconut fiber. The concentration variations used were 10%, 12%, and 14%. The time variations used were 20 and 30 minutes. From the results, it can be seen that the concentration, reaction time and type of raw material showed no significant effect on furfural yield. Young coconut fiber produced a higher yield than mature coconut fiber.

Abstract

The success rate in the seedling process is ofte hampered by inappropriate watering, which can cause the seedlings to rot and die. To overcome this problem, an efficient watering system with a high degree of precision is required. Mist irrigation is one of the appropriate methods because micro-sized water droplets are sprayed to maintain air humidity and reduce the rate of transpiration. This study aims to optimize the application of mist irrigation by evaluating the effect of nozzle height variations on plant growth. Using an experimental method, the variations included nozzle heights of 20 cm, 25 cm, and 30 cm. The parameters measured in this study included water discharge, plant height, number of leaves, and leaf area. The results showed that a watering height of 25 cm produced the best plant growth. The results of this study show that specific adjustment of the nozzle height is very important for improving the efficiency of mist irrigation in the seedling process. Keywords: mist irrigation, seedling, green mustard

Abstract

Cavendish bananas have great potential and are widely cultivated and consumed by the community, both processed and raw. A good banana is a banana that is ripe while it is still on the tree, but many farmers pick the bananas when they are not ripe. The harvested fruit will ripen without ripening with uneven ripeness and the resulting color is not attractive, therefore ripening is carried out. The ripening materials used are gamal leaves and banana leaves because it contains ethylene which functions in the fruit ripening process and is free from chemicals. The purpose of this study was to determine and analyze the best type of ripening material for the quality of Cavendish Banana (Musa acuminata Cavendish). The method used was the Completely Randomized Design experimental method with 1 factor, namely the type of ripening material such as gamal leaves and banana leaves. The ratio of gamal leaves used was 30%, 40%, and 50%, while the ratio of banana leaves was 30%, 40%, and 50%. Based on the results of the study, the ripening material had a significant effect on the quality of Cavendish Bananas. The ratio of gamal leaves of 50% is the best ripening material for the quality of Cavendish Bananas with a weight loss value of 1.035%, hardness of 31.328 (N/cm2), total dissolved solids of 12.936°Brix, water content of 71.674%, color (light) of 22.661, and color (hue) of 37.934.

Abstract

This research aims to determine a method for estimating evapotranspiration (ET) using radiation-based methods to obtain evapotranspiration results that are close to the Penman Monteith (PM) method for the Cupak Tangah Village area, Pauh District, Padang City. This research was conducted using the Caprio, Droogers and Allen, Berti and McGuinness and Bordne methods as a comparison method to the PM method. The parameters used are weather parameters such as solar radiation, temperature, humidity, wind speed, barometric pressure and others. Based on the analysis carried out, it was found that the empirical method that approaches the Penman Monteith evapotranspiration value is the McGuinness and Bordne method with the regression equation y = 0.8601x and R2 = 0.9864. In order, the methods for estimating evapotranspiration from those that are close to those that are not close to the PM results are the McGuinness and Bordne, Caprio, Droogers and Allen, and Berti methods.
