Abstract

The brown planthopper (BPH)-resistant rice, early maturity, and aromatic are expected by both farmers and consumers. The traits have been combined through gene pyramiding and some promising rice genotypes obtained. However the genetic control of BPH resistance and maturity is quantitatively inherited, it is therefore both molecular and phenotypic assessments would be tremendously helpful in selecting promising genotypes. The study aimed to obtain genotypes with such valuable traits. Rice lines were analyzed using molecular markers i.e., RM586, RM589, RM8213 (BPH resistant gene markers); RM7610 and RM19414 (early maturity markers), and IFAP (Internal Fragrant Antisense Primer) for detecting aromatic, and INSP (Internal Non-fragrant Sense Primer) for non-aromatic rice. Phenotypic assessment was performed for brown planthopper resistant-related traits, such as chlorophyll content, stomatal conductance, and trichome density. Other evaluations were heading date and aroma (using 1.7% KOH solution). Results showed that molecular markers for evaluating BPH resistance genes (Bph3, Bph4, Qbph4, and Bph17), aroma (fgr gene), and heading date (Hd2 and Hd3 genes) could differentiate genotypes, and they serve as perfect markers, except for heading date markers. Seven genotypes i.e., #2, #3, #4, #5, #6, #10, and #11 were related to all traits expected based on molecular marker analysis. Meanwhile, genotypes #1, #2, #4, #6, and #11 were similar to their parents based on phenotypic analysis. Pyramiding program based on molecular and phenotypic markers enables us to combine three valuable traits into one rice genotype as presented in this study

Abstract

Fish mashed jerky is a type of preserved food made from mashed fish meat, then added with spices such as sugar, coriander, galangal, salt, garlic, tamarind, onion, ginger and then molded and dried. Fish mashed beef jerky found in the market tastes sweet, and there is no addition of chili in the manufacture of minced fish jerky, while the people of Sumatra, especially the Minangkabau, like it spicy. Therefore, it is necessary to add additional spices that can add to the sweet taste of beef jerky by adding chilies to the manufacture of mashed fish jerky. This study aims to see the effect of the ratio of chili to sugar as much as 0:1, 1:0, 1:2, and 1:4 on the quality of shape, color, aroma, texture, and taste of jerky crushed catfish. This type of research is a pure experiment using a completely randomized design (CRD) method with three repetitions. The object of this research is jerky crushed catfish. The type of data is primary data sourced from 5 panelists who fill out the organoleptic test format. The data obtained were analyzed using statistical analysis (ANOVA), if Fcount > Ftable then continued with Duncan's test. The results of this study indicate that there is a significant effect of the chili to sugar ratio on the quality of color, texture, and taste (spicy). Meanwhile, on the quality of square and neat shape, fragrant aroma (typical of dried beef jerky) and taste (savory) there was no significant effect because Fcount < Ftable. The results of the quality test and the best hedonic (liking) of mashed catfish jerky were in the fourth treatment (X1) with a ratio of sugar to chili as much as 1:0 Keywords: Chili, Creamy Jerky, Catfish.

Abstract

Wet noodles are raw noodles that, before being marketed, undergo a boiling process in boiling water, with a water content of around 35%, and after boiling, the water content increases to 52%. In general, wet noodles are only made from the essential ingredients of wheat flour and eggs, with a protein content of 11.852%. This figure is low for one serving of food per human day. Therefore, it is necessary to think about alternative materials that can be used to increase the protein content of wet noodles. One of them is mackerel tuna. This study aims to describe the quality of wet noodles by adding mackerel tuna meat (10%) in terms of color, aroma, texture, and taste. The type of this research was an experiment conducted in October 2022 at the Culinary Study Program, Department of Home Economics, Faculty of Tourism and Hospitality, Universitas Negeri Padang. Data collection was carried out through organoleptic tests, which involved three expert panelists. The organoleptic test showed that the quality of wet noodles with the addition of mackerel tuna meat was light yellow, had a fragrant aroma, was chewy in texture, and had a savory mackerel tuna meat taste.

Abstract

Rapid digital transformation in the Industrial Revolution 4.0 era has shifted academic libraries into digital resource hubs, requiring librarians to adapt their competencies to meet the ever-evolving demands. This study is urgently needed to explore how the digital competency gap among librarians affects the effectiveness of library services in the digital era. This study aimed to measure the transformation of Universitas Negeri Padang Librarians in Industry 4.0. The research method used a sequential explanatory mixed-methods design, combining a cross-sectional survey of all 26 UNP librarians with follow-up in-depth interviews. The competencies assessed included device and software operation, information and data literacy, communication and collaboration, digital content creation, security, problem-solving, and self-development. Results showed that librarians excelled in basic skills such as ensuring internet connectivity (M = 7.08, SD = 1.055) and maintaining ethical digital communication (M = 6.85, SD = 1.190). However, challenges persisted in advanced areas such as software troubleshooting (M = 5.96, SD = 1.509) and creating innovative digital solutions to improve patron experience (M = 4.85, SD = 1.736). Interviews revealed a high dependency on technical support, limiting librarians’ independence in solving technical problems. The findings underscored the need for targeted training in problem-solving, digital innovation, and advanced application use, supported by improved infrastructure and access to sophisticated tools. This study concludes that improving the digital competencies of librarians is essential to support sustainable digital library services and strengthen the development of library science in Indonesia.

Abstract

Fresh noodles are widely consumed because of their chewy texture and ease of preparation. Product development in fresh noodles can be enhanced by using natural ingredients as colorants while increasing product value, including red dragon fruit peel, which contains anthocyanin pigments. This study aims to analyze the effect of substituting red dragon fruit peel extract on the sensory quality of fresh noodles, including color, aroma, chewy texture, resistance to breaking, and taste. An experimental design was employed using a Completely Randomized Design consisting of two treatments with three replicates: 150 ml of water as the control treatment (X₁) and 150 ml of red dragon fruit peel extract as the substitution treatment (X₂). Product quality was assessed through an organoleptic test involving 30 untrained panelists using a hedonic scale. Data were analyzed using an independent samples t-test. The findings show that the substitution of red dragon fruit peel extract significantly affected all sensory quality parameters of fresh noodles. Treatment X₂ obtained higher scores than treatment X₁ across all parameters, including color (5.34), aroma (5.00), chewy texture (5.09), resistance to breaking (5.10), and taste (5.11). These results indicate that red dragon fruit peel extract can improve the sensory quality of fresh noodles as a natural colorant. The study concludes that the best sensory quality was achieved through the substitution of 150 ml of red dragon fruit peel extract, suggesting its potential application in fresh noodle product development.

Abstract

Fresh noodles are widely consumed food products; however, their production commonly involves synthetic additives, including artificial colorants, which may pose potential health risks. Therefore, natural ingredients are needed as safer alternatives, one of which is pandan leaf extract, known for its natural green color and distinctive aroma. This study aimed to analyze the effect of pandan leaf extract substitution on the sensory quality of fresh noodles, including color, aroma, texture, resistance to breakage, and taste. An experimental method was applied using two treatments: 150 mL of water as the control treatment (X₁) and 150 mL of pandan leaf extract as the substitution treatment (X₂). Organoleptic evaluation was conducted by 30 panelists using a sensory assessment scale covering color, aroma, texture, and taste attributes. The collected data were analyzed using a pooled variance t-test, also referred to as an independent samples t-test, with SPSS version 22. The findings indicate that pandan leaf extract substitution had a significant effect on all sensory attributes of fresh noodles. Treatment X₂ obtained the highest mean scores across all assessed parameters, including color (5.36; light green), aroma (5.70; highly fragrant), chewy texture (5.17), resistance to breakage (5.00), and taste (5.04; savory). These results demonstrate that pandan leaf extract can improve the sensory quality of fresh noodles while functioning as a natural colorant and aroma-enhancing ingredient. The study concludes that substituting 150 mL of pandan leaf extract produces better overall sensory quality in fresh noodles and may support the development of food products using natural ingredients.
