Abstract

Penelitian ini melakukan tinjauan literatur mengenai efektivitas penggunaan biopestisida dalam pengelolaan hama tanaman. Biopestisida seperti Bacillus thuringiensis, produk berbasis neem, dan jamur entomopatogen Beauveria bassiana, telah terbukti efektif dalam mengurangi populasi hama dan meningkatkan hasil tanaman. Studi menunjukkan bahwa biopestisida menawarkan keuntungan signifikan dibandingkan dengan pestisida kimia konvensional, termasuk dampak positif terhadap kesehatan tanah dan biodiversitas, serta keamanan bagi organisme non-target seperti serangga penyerbuk. Namun, efektivitas biopestisida dipengaruhi oleh berbagai faktor, termasuk kondisi lingkungan dan metode aplikasi, yang memerlukan optimisasi lebih lanjut. Implikasi dari temuan ini sangat penting untuk praktik pertanian berkelanjutan, dengan potensi untuk mengurangi ketergantungan pada pestisida kimia dan mendukung keberlanjutan ekosistem pertanian. Penelitian ini juga mengidentifikasi kesenjangan pengetahuan yang membutuhkan penelitian lebih lanjut, termasuk dampak jangka panjang biopestisida dan ekonomi penggunaannya dalam skala besar. Hasil tinjauan ini menyarankan perlunya peningkatan kesadaran dan pemahaman petani tentang biopestisida serta pengembangan protokol aplikasi yang lebih standar dan efektif.

Abstract

[ISOLATION AND IDENTIFICATION OF STRAWBERRY FRUIT PATHOGENIC FUNGI DURING STORAGE]. Storing strawberry fruit is one way to extend its shelf life and maintain its quality during storage. However, during storage, there is still a risk of pathogenic fungi attack that can cause damage to the strawberry fruit. Pathogenic fungi attack on fruits can cause various types of damage, such as physical damage, color changes, loss of taste and aroma, as well as a decrease in nutritional quality. In addition, pathogenic fungi can also cause significant economic losses for farmers and producers. The purpose of this study is to identify the types of pathogenic fungi commonly found on strawberry fruit and analyze the severity of damage caused by pathogenic fungi. Identification of fungal species is carried out using microscopic methods and through examination of spore morphology. The pathogenic fungi that attack strawberry fruit are Penicillium spp., Colletotrichum spp., and Botrytis cinerea. Strawberry fruit stored at a cool temperature can suppress post-harvest disease symptoms compared to those stored at room temperature.

Abstract

Tomatoes are a type of fruit vegetable that has excellent prospects in agribusiness development due to its high economic value and high nutritional value. The successful growth and yield of tomato plants are greatly influenced by the condition of the planting medium and the availability of nutrients in the soil. The planting medium serves as a place for root attachment and as a provider of nutrients for plants. Therefore, selecting the right dose of organic fertilizer is very important to improve soil quality and support the growth of tomato plants. The purpose of this study was to obtain the best dose of cow manure and various planting media for the growth and yield of tomato plants. This study used a completely randomized design (CRD) with 2 factors. The first factor is the planting medium (M) which is PMK soil (M1) and sandy black soil (M2). The second factor is the dose of cow manure (D) which consists of 500 g/plant (D1), 1000 g/plant (D2), 1500 g/plant (D3) and 2000 g/plant (D4). The observation data were analyzed statistically by analysis of variance (F test). If the calculated F > F table 5%, then the difference between treatments was tested with Duncan's New Multiple Range Test (DNMRT) at a significance level of 5%. The results showed that the application of cow manure with a dose of 2000 g/plant had a significant effect on observations of plant height, number of fruits and fruit weight. The sandy black soil medium had a significant effect on observations of root length, root volume, number of fruits and fruit weight.

Abstract

This study investigated the effectiveness of artificial shelter structures (rumpon) in reducing cannibalism and improving the survival rate of baung fish (Mystus nemurus) fry cultured in circular ponds. Cannibalism is one of the major constraints in baung fish hatchery production because it significantly decreases fry survival and productivity. A Completely Randomized Design (CRD) consisting of four treatments, namely control (without rumpon), full rumpon, ¾ rumpon, and ½ rumpon, with three replications for each treatment was applied. Parameters observed included survival rate and water quality (temperature, pH, and dissolved oxygen). Data were analyzed using analysis of variance (ANOVA), while water quality parameters were analyzed descriptively. The results showed that the full rumpon treatment produced the highest survival rate (56%), followed by ½ rumpon (50%), ¾ rumpon (45%), and control (13%). The presence of rumpon increased habitat complexity, reduced direct interactions among fry, minimized cannibalistic behavior, and consequently improved survival. This study demonstrates that coconut leaf rumpon can serve as a simple, environmentally friendly, and low-cost habitat modification technology to enhance baung fish hatchery performance.

Abstract

Fusarium wilt caused by Fusarium oxysporum f.sp. capsici is one of the most destructive diseases affecting red chili pepper cultivation because it significantly reduces plant growth and yield. Disease management that still relies on synthetic fungicides may increase environmental pollution and promote pathogen resistance; therefore, environmentally friendly control alternatives are required. This study aimed to evaluate the effectiveness of several local rhizobacterial isolates as antagonistic agents against Fusarium wilt in red chili pepper. The novelty of this study lies in the evaluation of indigenous rhizobacterial isolates with dual functions as antagonistic agents against Fusarium oxysporum f.sp. capsici and as plant growth-promoting rhizobacteria (PGPR) capable of enhancing red chili pepper growth under both in vitro and in vivo conditions. The results showed that all rhizobacterial isolates significantly inhibited pathogen growth. Isolate UBI-Rz04 exhibited the highest inhibition rate of 85.78% and the lowest fungal biomass (0.03 g) under in vitro conditions. In the in vivo assay, isolate UBI-Rz01 reduced disease incidence to 44.67%, compared with 80.00% in the control, and suppressed the pathogen population to 3.33 × 10⁵ CFU/g soil. Rhizobacterial application also improved red chili pepper growth. These findings indicate that local rhizobacteria have strong potential as environmentally friendly biological control agents for sustainable red chili pepper cultivation.

Abstract

Modern agriculture faces increasing challenges from soil-borne fungal pathogens such as Fusarium oxysporum, Rhizoctonia solani, and Sclerotium rolfsii, which cause severe root and wilt diseases and significantly reduce crop productivity. This study employed a qualitative–descriptive approach supported by controlled laboratory experiments to evaluate the potential of agricultural waste as an alternative, low-cost substrate for producing antifungal rhizobacterial biopesticides. Six types of agricultural waste—rice straw, rice husk, corn cob, sugarcane bagasse, coffee husk, and soybean residue—were assessed based on their C/N ratio, lignin content, biodegradability, and nutrient availability. The results indicated that substrates with moderate C/N ratios (15–25) and low lignin content, particularly soybean residue and sugarcane bagasse, promoted optimal rhizobacterial colonization, robust biofilm formation, and high production of antifungal metabolites such as chitinase and siderophores. Rhizobacteria cultured on soybean residue exhibited the strongest inhibition zone against Fusarium oxysporum (20.5 mm) and the highest plant protection efficacy (88%), with biopesticide stability maintained for up to 120 days. Two conceptual models, Substrate Structure Colonization (SSC) and Media Metabolite Effectiveness (MME), are proposed to explain the relationship between substrate structure, metabolite biosynthesis, and biopesticide performance. These findings provide a sustainable strategy for converting agricultural waste into high-value bio-based inputs, supporting circular economy practices and green agriculture initiatives.
