Abstract

Shallots are a high-value horticultural commodity. But so far, they have been mostly developed in the highlands. Shallots are plants that like areas with hotter air temperatures, so they are suitable for cultivation in the lowlands. Still, the soil that is widely available in the lowlands of the city of Padang is Ultisol. Ultisol contains high clay, so the soil becomes dense, the available nutrients are low, and the ground has difficulty passing water. Using Ultisol as a land for planting shallots, it requires using organic fertilizer in large doses. One of the agricultural waste products that is available and has yet to be widely used in Lambung Bukik Village is rice straw. Rice straw is a waste that is difficult to decompose. Therefore, it is necessary to use a decomposer to get compost faster. Training on making rice straw compost and making demonstration plots was carried out in Lambung Bukik, Padang City, to support the development of shallot cultivation on lowland Ultisol. Farmers are very enthusiastic about learning to cultivate shallots and making organic fertilizer from rice straw.

Abstract

Tamarillo (Solanum betaceum), a fruit native to South America, thrives in the highlands of Indonesia and is rich in bioactive compounds with significant potential for functional food development. This study employs a comprehensive literature review of 108 indexed national and international journals to explore the application of tamarillo in food products. Despite its nutritional benefits—such as high vitamin C, antioxidants, and dietary fiber—tamarillo remains underutilized in culinary applications. Current products incorporating tamarillo include syrup, ice cream, jam, soft candy, jelly, steamed bread, cheese, and yogurt. These products leverage tamarillo’s bioactive properties, such as its antioxidant and anti-inflammatory effects, which contribute to health benefits like improved digestion, immune support, and chronic disease prevention. However, further research is needed to expand its applications and optimize its potential in functional foods

Abstract

Flexible polyurethane foams is the most produced foam compared to other types of polyurethane foams. The raw material for polyurethane foams is usually derived from petroleum polyols. The availability of petroleum which is getting thinner needs to be sought alternative raw materials for polyurethane foams from vegetable polyols (biopolyols). The relatively high productivity of palm oil causes the potential of palm oil to be used as raw material for flexible polyurethane foams compared to other vegetable oils. Various formulations and modifications that have been made in synthesizing flexible polyurethane foams from various types of biopolyols are aimed at increasing the usability and to produce flexible polyurethane foams with characteristics close to polyols made from petroleum-based foams.Busa poliuretan fleksibel merupakan busa yang paling banyak diproduksi dibanding dengan jenis busa poliuretan yang lain. Bahan baku busa poliuretan biasanya berasal dari poliol minyak bumi. Semakin berkurangnya ketersediaan  minyak bumi,  maka perlu dicari alternatif  bahan baku busa poliuretan dari poliol nabati (biopoliol). Produktivitas kelapa sawit yang cukup tinggi menyebabkan minyak kelapa sawit cukup potensi digunakan sebagai bahan baku busa poliuretan dibandingkan dengan minyak nabati lain. Berbagai formulasi dan modifikasi yang telah dilakukan dalam mensintesis busa poliuretan fleksibel  dari berbagai jenis biopoliol  bertujuan untuk meningkatkan daya guna dan untuk menghasilkan busa poliuretan fleksibel dengan karakteristik mendekati busa berbahan baku poliol dari minyak  bumi.

Abstract

Spodoptera frugiperda is a major invasive pest of maize that requires effective control strategies. Entomopathogenic fungi are promising biological control agents because they can infect larvae and disrupt insect development. However, information on indigenous fungal isolates from West Sumatra, Indonesia remains limited. Moreover, their effects on post-larval development of S. frugiperda are still poorly understood. This study aimed to evaluate the pathogenicity of several fungal isolates against S. frugiperda under laboratory conditions. The experiment was arranged in a Completely Randomized Design (CRD) with eight treatments and four replications. The treatments consisted of six fungal isolates (Beauveria bassiana BBWS, B. bassiana BBPD, Metarhizium anisopliae B22C, M. anisopliae KRJ, Trichoderma asperellum A116, T. asperellum S2D11) and two controls (sterile distilled water and cypermethrin). Fungal suspensions were applied to second-instar larvae at 1 × 10⁸ conidia mL⁻¹. All data were analyzed using ANOVA followed by the LSD test at the 5% level. This study showed that the entomopathogenic fungal isolates tested affected the survival and postlarval development of S. frugiperda under laboratory conditions. The fungal treatments caused larval mortality ranging from 40 - 70% and reduced the proportion of larvae into the pupal and adult stages. Among the tested isolates, B. bassiana BBWS was the most effective, causing the highest larval mortality, the shortest LT₅₀, and the lowest pupal and adult formation. However, further research is needed to confirm the pathogenicity mechanisms of the isolates, their conidial viability and stability during storage, and their efficacy under greenhouse and field conditions.

Abstract

Purpose: This work aimed to analyze the profiles of amino acids in the ficin enzyme isolated from Ficus aurata (Miq.), and to determine the efficiency of these amino acid concentrations under two types of drying – solar drying and freeze drying. Methodology: The enzyme ficin was obtained from fig tree, and the presence of amino acids was determined by UPL chromatography. The applied methods of drying were solar and freeze. However, the primary objectives were aimed at investigating the influence of these treatments on the level of amino acids present in all the samples. Results: The findings indicated that freeze drying techniques retained more amino acids in figs than was observed in the case of solar drying. In particular, the amount of L-glutamic acid in freeze drying was 2.39 mg/g, while that of solar drying was 1.43 mg/g. Similar results were observed in L-lysine and L-aspartic acid, which were relatively higher in freeze drying than solar drying, with concentrations of 2.43 mg/g and 2.55 mg/g, respectively, as opposed to 0.99 mg/g and 1.76 mg/g in solar drying. Besides, freeze drying showed better L-serine, L-phenylalanine, and L-histidine preservation. Findings: It was observed that freeze drying gave the best opportunity to reduce the loss of amino acid of the ficin enzyme. The drying method, in particular, resulted in a concentration of some important amino acids like L-glutamic acid, L-lysine, L-aspartic acid, L-serine and L-phenylalanine, and L-histidine as compared to solar drying. Novelty: This study focused on different types of solar energy and freeze energy economic systems in enzymatic activities in the ficin enzyme extracted from Ficus aurata (Miq.). The novel contribution of this research lies in its objective, which is to show how the drying methods used affected the retention of the most influential and critical amino acids in the enzymatic processes. Originality: The novel aspect of the study was the attachment of ultra vortices to different drying techniques, such as solar drying and freeze drying in select ficin enzymes from Ficus aurata. It opens up a new perspective toward the development of drying parameters for the enhancement of important enzymatic characters from this particular variety. Conclusion: This research considers the changes in amino acid content during the drying of ficin enzyme from Ficus aurata through different drying methods. It is shown that freeze drying enhances the retention of critical amino acids and is thus one of the most efficient methods for the enzymatic processing of this plant species. Type of Paper: Empirical research paper.

Abstract

Entomopathogenic fungi (CEPs) possess dual potential as biological control agents and endophytes that modulate plant physiological processes. Single applications of CEPs often provide suboptimal protection and growth support, necessitating a synergistic, interspecies combination approach. This study aimed to evaluate the effects of single and combined inoculations of CEPs on the growth, chlorophyll content, and yield components of shelled corn (Zea mays L.). A Randomized Block Design (RBD) with eight treatments and four replications was employed. The treatments included Beauveria bassiana (BBWS), Metarhizium anisopliae (B22C), and Trichoderma asperellum (A116), applied singly or in combination via seed soaking for six hours. Sterile distilled water served as the control. Observed parameters included plant growth, leaf chlorophyll content, and yield components. Data were analyzed using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test at the 5% significance level. Results indicated that fungal inoculation had no significant effect on corn vegetative growth six weeks after planting. However, the combination of B. bassiana and M. anisopliae produced the highest total chlorophyll content (1,101 μg g⁻¹), whereas single inoculations decreased chlorophyll levels, likely due to carbon costs during the initial phase of endophyte colonization. Importantly, the combination of M. anisopliae and T. asperellum yielded the highest number of kernels per ear, ear weight, and 100-kernel weight. This research advances previous studies by demonstrating that synergistic fungal combinations effectively mitigate early-phase carbon costs, thereby maximizing crop yields compared to single applications. Therefore, the combination of M. anisopliae and T. asperellum is recommended as a biofertilizer formula and biocontrol agent for sustainable corn kernel production.

Abstract

The titan arum (Amorphophallus titanum (Becc.)), an endangered and endemic flora from the island of Sumatra, faces a significant risk of extinction. Conservation efforts for the titan arum were undertaken, including in vitro conservation through tissue culture. The study aimed to determine the optimal concentration of the growth regulator Benzyl Amino Purine (BAP) for inducing shoot formation in titan arum and to observe cellular changes during the shoot stage through histological test. This research was conducted from November 2023 to March 2024 at the Tissue Culture Laboratory, Andalas University. The experiment was arranged in a Completely Randomized Design (CRD) with five treatment levels: 2, 3, 4, 5, and 6 ppm.  Data analysis was performed using an F-test at a 5% significance level. If the F-test showed significant differences, further testing was carried out using Duncan's Multiple Range Test (DMRT) at a 5% significance level. Meanwhile, data on explant rooting percentage and root count were presented as means and standard deviations. Results indicated that various concentrations of BAP could induce shoots formation of Amorphophallus titanum Becc., with the percentage of explants forming shoots reaching 80–95%.  The concentration of 5.0 ppm BAP was the most effective, yielding the highest average number of shoots at 7.80. Histological test revealed cell enlargement at the shoot tips. This research is pivotal for the conservation of titan arum and promotes further studies in in vitro culture techniques.

Abstract

Banana plants have a wide genetic diversity in Indonesia, but research on the morphological characterization of this fruit is limited. The purpose of this study was to conduct a systematic literature review on scientific trends, production, and knowledge, specifically the morphological characterization of the banana plant in Indonesia. An examination of 290 published documents in the Google Scholar database from 2012 to 2022 was carried out for this purpose. To reveal the overall trend of this topic, the co-occurrence of keywords was visualized and studied using VOSviewer software. The study findings revealed a linear increase in research trends over the years regarding the diversity of banana cultivars in some regions of Indonesia. Bibliometric mapping identified several primary research focuses, including the identification and characterization of the distinctive morphological diversity of banana plants, the utilization of various plant parts (such as leaves, stems, humps, and peels), as well as the analysis of nutritional composition and physical properties of processed products. Through overlay and density visualization, this study concludes that research on the morphological characterization of banana plants in Indonesia still holds extensive potential for future development to support the breeding of new superior varieties.

Abstract

Rhizoctonia solani Kühn is a pathogenic fungus that causes sheath blight disease in rice. One effective strategy for managing this disease is the use of biological control, particularly through consortia of endophytic bacteria. This study aimed to identify the most effective endophytic bacterial consortium for suppressing sheath blight severity while also enhancing rice growth and yield. A Completely Randomized Design (CRD) was aemployed with six treatments, three replications, and three experimental units per treatment. The treatments included four bacterial consortia composed of combinations of Bacillus thuringiensis LmD13, Ochrobactrum intermedium LmB1, and Stenotrophomonas maltophilia LmB35, along with positive and negative controls. The experiment involved treating rice seeds and soaking seedling roots with the bacterial consortia before transplanting. R. solani was inoculated onto the rice leaf sheaths 40 days after planting. The effectiveness of each consortium as a biocontrol agent was evaluated based on incubation period, disease incidence, disease severity, and the area under the disease progress curve (AUDPC). Their biostimulant potential was assessed through parameters related to seedling growth, plant development, and yield. Results indicated that the endophytic bacterial consortia effectively suppressed sheath blight and significantly improved rice growth and production. Notably, the consortium of B. thuringiensis LmD13, O. intermedium LmB1, and S. maltophilia LmB35 extended the incubation period to 35 days post-inoculation and reduced disease incidence, severity, and AUDPC to 22.22%, 0.29%, and 1.01, respectively. This consortium also enhanced rice yield, with fresh and dry grain weights reaching 72.78 g and 63.02 g, respectively, compared to the positive control. These findings suggest that this bacterial consortium holds strong potential as a biocontrol agent and yield enhancer in rice cultivation.

Abstract

Spodoptera frugiperda J.E. Smith is an invasive pest of corn, requiring effective and environmentally friendly control strategies. This study aimed to evaluate the effectiveness of three entomopathogenic fungal (EPF) isolates, namely Beauveria bassiana WS, Metarhizium anisopliae B22C, and Trichoderma asperellum A116, tested as single isolates or in combination against S. frugiperda eggs and larvae. The experiment used a Completely Randomized Design (CRD) with eight treatments (three single treatments, four combinations, and a control) and four replications. Conidial suspensions were applied by spraying onto eggs and second-instar larvae. Parameters observed included the percentage of unhatched eggs, larval mortality, and pupal and adult development. Chitinase, protease, and lipase activities were qualitatively tested to support the identification of pathogenicity mechanisms. Data were analyzed using analysis of variance (ANOVA), followed by the LSD test at a 5% significance level. The results showed that EPF combinations increased mortality and inhibited the development of S. frugiperda. The combination of B. bassiana WS + T. asperellum A116 was the most effective treatment, inhibiting egg hatching by 85% and reducing pupal and adult formation to 25.95% and 12.96%, respectively. The highest mortality of first-instar larvae was observed in the single treatment of B. bassiana WS and the tertiary combination of B. bassiana WS + M. anisopliae B22C + T. asperellum A116, at 24.18% and 22.91%, respectively. Consistent enzymatic activity indicated potential biocontrol synergy through the production of cuticle-degrading enzymes. This combination is recommended for field-scale testing as an environmentally friendly alternative to reduce dependence on chemical insecticides.
