Abstract

Melon is a fruit commonly served as a dessert at various dining events. Its nutritional content and pleasant taste make it popular among consumers. Due to high market demand, melon production continues to increase; however, one of the problems in production is the excessive use of inorganic fertilizers. This study aimed to determine the effect of trichocompost dosage on fruit weight, diameter, and sugar content of melon (Cucumis melo), as well as to examine the presence of interaction between the treatments. The research was conducted at the Ragunan Agro-education Tourism area and the Laboratory of the Faculty of Agriculture, Universitas Respati Indonesia, from March to July 2025. The experiment was carried out in the field using a factorial Completely Randomized Design (CRD). The study consisted of two treatment factors. The first factor was trichocompost dosage with four levels: P0 = without trichocompost fertilizer, P1 = 500 g trichocompost, P2 = 1,000 g trichocompost, and P3 = 1,500 g trichocompost. The second factor was melon variety, consisting of V1 = Sweet Net variety and V2 = Rock Melon variety. Each treatment was replicated three times. The observed variables included fruit weight (g), fruit diameter (mm), and sugar content (°Brix). The results showed that trichocompost dosage significantly affected fruit weight and diameter but had no significant effect on sugar content. The melon variety factor had no significant effect on all observed variables, and no interaction was found among the treatments for all variables.

Abstract

Kawista (Limonia acidissima L.) is a nutrient-rich tropical plant with antioxidant, anticancer, antidiabetic, and anti-inflammatory benefits. Despite its usefulness, it remains rare due to slow growth—taking up to 15 years to bear fruit. In regions like Rembang and Karawang, it is used in traditional foods and drinks. Tissue culture offers a faster, more efficient method for kawista propagation. This research aimed to determine the optimal concentration combination of Naphthalene Acetic Acid (NAA) and Benzyl Amino Purine (BAP) for promoting callus growth from kawista (Limonia acidissima L.) leaf explants through tissue culture techniques. The study was conducted at the Plant Biotechnology Laboratory, Academic Support Unit (UPA), University of Singaperbangsa Karawang, from February to March 2025.mThe experimental method employed a Completely Randomized Design (CRD) with a single factor involving various concentration combinations of NAA and BAP. The treatments consisted of six combinations, each replicated five times: A (control), B (1 ppm NAA + 5 ppm BAP), C (3 ppm NAA + 5 ppm BAP), D (5 ppm NAA + 5 ppm BAP), E (7 ppm NAA + 5 ppm BAP), and F (9 ppm NAA + 5 ppm BAP). The results demonstrated that the combination treatments significantly affected callus initiation time, callus growth percentage, callus diameter, and callus weight. The most effective treatment was F (9 ppm NAA + 5 ppm BAP), which showed the shortest average time for callus emergence 14.87 days, the largest average callus diameter 1.66 cm, and the highest average callus weight 0.39 gram.

Abstract

Oil palm frond has potential to be utilized as activated charcoal for plant tissue culture as phenolic compound absorber which causes browning and to promote explant growth. The objectives of this study were to produce activated charcoal from palm oil fronds which has characteristics in accordance with Indonesian National Standards (SNI 06-3730-1995) and commercial activated charcoal for plant tissue culture, to obtain larger activated charcoal pores and clean from the impurities, and to find optimum activated temperature in producing oil palm frond’s activated charcoal using physical-chemical activation method. The research design used was a non actorial - completely randomized design consisted of 4 treatments and 3 replications, namely E0 (control, without physical activation), E1 (physical activation of 450 °C), E2 (physical activation of 600 °C), E3 (physical activation of 750 °C). The parameters observed were the yield of activated charcoal (%), moisture content (%), ash content (%), iodine absorption (mg/g), volatile matter (%) and surface morphology of activated charcoal. The yield of activated charcoal ranged from 0.56 to 1.09%. All treatments significantly affected moisture content, ash content, iodine adsorption, and volatile matter. Overall, the characteristics of the activated charcoal met the SNI standards and commercial tissue-culture charcoal, except for moisture content. The 750 °C activation temperature (E3) was identified as the optimum condition, producing low moisture and ash content, high iodine adsorption, low volatile matter, and larger, cleaner pore morphology

Abstract

Fusarium wilt disease caused by the fungus Fusarium oxysporum is one of the main diseases affecting shallots and can cause losses of up to 50%. Gliocladium sp. has the potential to be used as a biological agent because it is able to control pathogens and suppress the development of fusarium wilt disease. This study aims to determine which carrier material is most effective in producing the highest spore density of Gliocladium sp. and its antagonistic ability in reducing the intensity of Fusarium wilt disease in red onions. The study was conducted experimentally using a completely randomised single-factor design to test the spore density of Gliocladium sp. on four types of carrier materials: U₁ (rice bran), U₂ (rice), U₃ (corn cobs), and U₄ (sorghum seeds) with six replications, and a single-factor Randomised Block Design to test Gliocladium sp. against Fusarium oxysporum wilt disease with seven treatments: G₀ (control), G₁ (fungicide), G₂ (Gliocladium sp. from rice bran), G₃ (Gliocladium sp. from rice), G₄ (Gliocladium sp. from corn kernels), G₅ (Gliocladium sp. from sorghum seeds), G₆ (commercial Gliocladium sp.), and four replications. The results of the study indicate that the use of various carrier materials significantly affects the spore density of Gliocladium sp. and in suppressing Fusarium wilt disease in red onions (Fusarium oxysporum f.sp. cepae). Treatment U₂ (rice) produced the highest spore density, 2.70 x1011 spores/ml. However, treatment G₃ (Gliocladium sp. on rice) yielded suboptimal results in terms of germination rate (20.0%) and disease severity (100%), thus failing to effectively suppress Fusarium wilt disease.

Abstract

Sheath blight (Rhizoctonia solani) is an important disease of rice plants that can cause yield losses of up to 20% and will continue to increase if the severity is high. Excessive use of fungicides has a negative impact on living things and the environment. The solution that can be found is to utilize biological agents such as Trichoderma sp. to control plant diseases. The purpose of this study was to determine the effect of using several carrier materials on the growth of Trichoderma sp. and its ability to suppress rice sheath blight. This study used an experimental method with a Completely Randomized Design (CRD) Single Factor for the growth test of Trichoderma sp. on several carrier materials consisting of 4 treatments (B1, B2, B3, B4) and 6 replications, as well as a Single Factor Randomized Block Design (RBD) for the test of the ability of Trichoderma sp. to suppress sheath blight with 7 treatments (F0, F1, F2, F3, F4, F5, F6) and 4 replications. The results of the study showed that Treatment B4 (Parboiled Rice + Dry Chicken Manure + Sugar) produced the best growth of Trichoderma sp., and each Trichoderma sp. treatment had no significant effect on seed germination and the incidence of leaf sheath blight disease

Abstract

Kale plant (Brassica oleracea L. Var. Acephala) is a horticultural crop that belongs to the Brassicaceae family. Non-optimal cultivation practices and limited agricultural land are problems faced because agricultural land has been converted for community and residential development. Efforts are made with other alternatives, planting systems that save land, namely by using the NFT hydroponic system. The purpose of this study was to analyze and determine the best response to the use of planting media for the yield and growth of kale plants (Brassica oleracea L. Var. Acephala) in the NFT hydroponic system. This experiment used a single-factor RAL (Completely Randomized Design) environmental design experiment consisting of 6 treatments and 4 replicates, namely: A (Rockwool); B (Cocochip); C (Sponge); D (Floral Foam); E (Waste Tea Dip); F (Cotton). The data obtained were analyzed by F test analysis and Duncan Multiple Range Test (DMRT) further test at 5% level. The results showed a significant effect of various types of planting media on all parameters.

Abstract

Cylas formicarius is a major pest of sweet potato plants in Indonesia that can disrupt and harm farmers because this pest can reduce sweet potato yields by up to 100%. Beauveria bassiana is an entomopathogenic fungus that has the potential to be a plant pest control agent. Papaya leaves are one of the plants that have the potential to control pests. This study aims to obtain effective treatment increasing mortality and suppressing the attack of Cylas formicarius. The method used was an experimental method with a single-factor Completely Randomized Design (CRD) consisting of 7 treatments and 4 replications: A (Control aquadest); B (40% Papaya leaf extract); C (60% Papaya leaf extract); D (80% Papaya leaf extract); E (Beauveria bassiana 109 + 40% Papaya leaf extract); F (Beauveria bassiana 109 + 60% Papaya leaf extract); G (Beauveria bassiana 109 + 80% Papaya leaf extract). Data were analyzed using F-test and Duncan Multiple Range Test (DMRT) at a 5% significance level. The results showed that the treatment G (Beauveria bassiana 109 + 80% Papaya leaf extract) achieved the highest mortality of 100%. Treatment F (Beauveria bassiana 109 + 60% Papaya leaf extract) gave an average mortality result of 82,50%. The best average LC50 concentration was 63,40%. Thus, treatment F (B. bassiana 109 + 60% Papaya leaf extract) is more recommended to controlling and suppressing the population Cylas formicarius as it requires less raw material and so it is more efficient

Abstract

Rice is the staple food for 90% of the Indonesian population, yet its grain Zn content is generally low, contributing to potential micronutrient deficiencies. Japonica rice, known for its sticky texture, has the potential to contain higher Zn levels, making it a promising candidate to support the national stunting prevention program. This study aimed to evaluate the morphological variation of high-Zn Japonica rice lines cultivated in irrigated lowland fields and to identify lines that outperform existing varieties. A single- factor Randomized Complete Block Design (RCBD) was used, consisting of 56 lines and 4 control varieties, with two replications, resulting in 120 experimental units. Observed variables included plant height, number of productive tillers, flowering time, maturity time, and panicle length. Data were analyzed using the F-test, followed by the Least Significant Increase (LSI) test at a 5% significance level when significant effects were detected. Line IR 134409-B-41-1-1 had the tallest plants, averaging 103.75 cm. The highest number of productive tillers was found in IR 134422-B-26-1 (32.75 tillers). The earliest flowering was observed in IR 134422-B-37-1 (58 days after sowing), and the earliest maturity in IR19K1059 (92 days). The longest panicle length was recorded in B14806D-MR-6-4-KN-5 (26.17 cm). Line IR 134421-B-31-1 showed high potential with a dry milled grain yield of 7.53 tons/ha and a Zn content of 31.15 ppm, closely matching the control Inpari IR Nutri Zinc
