Abstract

The increasing expansion of palm oil plantations can exacerbate climate change due to high deforestation rates and increased CO2 emissions. This study aims to identify carbon sequestration through oil palm frond biochar as a mitigation strategy for CO2 emissions and land degradation. This research  conducted at Palm Oil Plantation on Siluman B, Labuhanbatu District.  This study  using a Factorial Randomized Block Design  with two factors, 3 × 2, and 5 replications, resulting in 30 experimental units. The main factor is biochar  A0 = No biochar, A1 = 1.5 kg, A2 = 3.0 kg. The second factor is the method of biochar application which includes B0 = Incorporation into soil, B1 = Applied on the soil surface. Biochar significantly increases soil carbon stocks by nearly double, proving its role in carbon sequestration. Application of biochar on the surface and incorporation into soil have the same efect to increase soil carbon sequistration. Biochar fundamentally improves soil fertility by increasing the Cation Exchange Capacity, total N content, and the availability of essential base cations, while lowering the C/N ratio to a more ideal level. The method of incorporating biochar into the soil proved superior for enhancing CEC, making it the recommended practice.

Abstract

ABSTRACTThe increase on rice plant growth can be done through the application of organic and inorganic fertilizers, as well as the use of appropriate varieties. This research aimed to examine the effect of a combination of organic and inorganic fertilizer doses and the use of varieties on improving rice plant growth and nutrient level. The research was conducted from June to August 2025 located in Sudimoro Village, Megaluh Subdistrict, Jombang Regency. This research used a factorial randomized block design (RBD) with two factors and three replications. Factor 1 is a combination of biological and inorganic fertilizer doses consisting of 9 levels of treatment, namely: 100% inorganic fertilizer + no biological fertilizer (P1), 75% inorganic fertilizer + no biological fertilizer (P2), 50% inorganic fertilizer + no biological fertilizer (P3), 100% inorganic fertilizer + 5 ml biological fertilizer (P4), 75% inorganic fertilizer + 5 ml biological fertilizer (P5), 50% inorganic fertilizer + 5 ml biological fertilizer (P6), 100% inorganic fertilizer + 10 ml biological fertilizer (P7), 75% inorganic fertilizer + 10 ml biological fertilizer (P8), and 50% inorganic fertilizer + 10 ml biological fertilizer (P9). Factor 2 is the rice plant varieties, namely: Inpari 32 (V1) and Ciherang (V2). The observations conducted included growth observations, namely plant height, number of leaves, number of tillers and dry weight of plants observed at 15, 30, 45, and 60 days after planting and NPK level of plants observed at 60 days after planting. The results showed that the combination of 100% inorganic fertilization + 10 ml of organic fertilizer generally increased plant height, number of leaves and dry weight of rice plants. The use of the Ciherang variety resulted in better plant height, number of leaves and dry weight of rice plants compared to the Inpari 32 variety. The use of a combination of inorganic and organic fertilizer had a significant effect on increasing the number of tillers of rice plants of the Inpari 32 variety compared to the Ciherang variety. The nitrogen content of rice plants (1.17 to 1.99%) is included in the deficiency category, while the phosphorus content (0.14 to 0.31%) and potassium (1.45 to 2.22%) are included in the excess category, where the addition of biofertilizer has an effect on increasing the nitrogen, phosphorus and potassium content of rice plants compared to without biofertilizer.Keywords: Rice; Biological Fertilizer; Inorganic Fertilizer; Varieties; Growth.

Abstract

Arachis hypogaea L. (Fabales: Fabaceae), a vital palawija commodity in Indonesia, has seen declining production in Jawa Timur in recent years. Among agricultural challenges, biotic factors like pest and disease infestations significantly impact yield. Damping-off, caused by the fungal pathogen Sclerotium rolfsii, is a major disease impacting groundnut cultivation. Biocontrol agents offer a promising alternative to synthetic fungicides for managing plant pathogens. This study evaluated the effectiveness of various Trichoderma spp. isolates in controlling S. rolfsii damping-off disease in Bison groundnut variety based on four key parameters: incubation period, disease incidence and severity, and control efficacy. The results demonstrated that all tested Trichoderma spp. isolates had the ability to suppress damping-off disease. Notably, isolate TB01 exhibited the best performance significantly prolonging the pathogen's incubation period, reducing disease incidence and severity in both pre- and post-emergence phases, and demonstrating the highest control efficacy 47.95% “sufficiently capable”. This study highlights the potential of Trichoderma spp. as a sustainable and eco-friendly biocontrol agent for managing S. rolfsii damping-off in groundnut cultivation. The successful application of isolate TB01 offers a promising approach for farmers seeking effective disease control strategies with minimal environmental impact.

Abstract

The main product of the palm plant is sap, which results from tapping the male flowers into palm sugar, soft drinks, vinegar, and alcohol. Apart from that, sugar palm plants can also produce food products such as palm fruit from female fruit, sugar palm flour for food in the form of cakes, bread, and biscuits, which comes from processing the pith of the plant stem and can be used as a source of bioethanol production.  However, there is limited research on how sugar palm agroecosystems influence the dynamics of herbivorous pests and predatory insect populations, making it essential to understand these interactions for sustainable plantation management. This research aimed to study the influence of sugar palm agroecosystems on the presence of herbivorous insect pests and predatory. The research was conducted in Nagari Labuah Gunung, Lima Puluh Kota Regency, West Sumatra Province. Observations were conducted on stretches of sugar palm plants aged 7-8 years or already producing. The sample plants were determined using purposive sampling, and labels were given to each tree that was part of the sample plants. Identify herbivorous and predatory insects obtained from the field and calculate the attack level. From the research carried out, it was found that management of sugar palm plants affects the presence of herbivorous and predatory insect pests, where no herbivorous insect pests were found on sugar palm plantations, and no herbivorous insect pest attacks were found on sugar palm plants on people's plantation land. Many types of predatory insects are found in sugar palm plantations, including Hymenoptera, Coleoptera, Orthoptera, Mantodea, Dermaptera, and Diptera.  These findings contribute to a deeper understanding of the ecological balance within sugar palm agroecosystems, emphasizing the potential role of natural predators in maintaining pest-free plantations and supporting sustainable agricultural practices.

Abstract

Local rice seeds from Bangka have great potential for food security. Seeds stored in the wrong place can experience a decrease in quality. This study aims to assess the germination pattern and quality resilience of local Bangka rice seeds under different storage methods. The research was conducted from February to September 2024 at the Seed Laboratory and Plant Breeding, Bangka Belitung University. The study used a completely randomized design (CRD) with a split plot pattern. The first factor consists of six accessions of local rice from Bangka (Mukot, Jawa, Ungu, Pulut Hitam, Balok Merah, and Mayang Hutan). The second factor comprises seven storage methods (cans, 40-micron plastic, 120-micron plastic, plastic bags, plastic containers, nursery trays, and panicles). This study shows significant differences in the germination patterns of local Bangka rice seeds stored in various media for 0, 2, 4, and 6 months. The Jawa access had the highest germination rate (78.8%) with an optimal storage time of 4 months, while storing seeds using panicles gave the best results (82.3%) compared to other media. The Balok Merah access excelled in maintaining seed quality. The local Bangka rice access, namely Jawa and Balok Merah, stored using the panicle storage method, can be applied by farmers and the community to maintain seed quality.

Abstract

Diamondback moth (P. xylostella) is a major pest of Brassicaceae crops. This study investigates host plant preferences of P. xylostella and their impact on larval growth across five Brassicaceae species (cabbage, green mustard, cauliflower, kale, and kailan). This experimental using a Completely Randomized Design (CRD) with five replications, we assessed oviposition behavior and larval growth efficiency. The research was conducted at the Agrotechnology Laboratory, Faculty of Agriculture, University of Jember. Our findings reveal that P. xylostella preferred kale (B. oleracea var. sabellica) for oviposition (19 eggs on average), followed by green mustard, cabbage, kailan, and cauliflower. Analysis of the efficiency of conversion of food (ECI and ECD) were highest in larvae fed on kailan leaves, suggesting enhanced larval development (ECI = 0.1966, ECD = 0.2074). These findings suggest that kale could be used as a trap crop in integrated pest management (IPM) strategies to mitigate damage on economically important Brassicaceae crops.

Abstract

Yard-long bean production in Indonesia has declined due to environmental factors and pest infestations, particularly by Aphis craccivora, a vector of viruses such as Bean common mosaic virus (BCMV). Generally, A. craccivora has been controlled using insecticides; however, their use poses limitations including toxicity, the development of resistance, environmental concerns, and disruption of pest–predator dynamics due to excessive application. As a promising alternative, chitosan has demonstrated potential in inhibiting aphid feeding, reducing reproduction rates, delaying disease incubation periods, and lowering BCMV titres. This study assessed the effects of both pure and commercial chitosan on A. craccivora in yard-long beans. The evaluation focused on antixenosis, antibiosis, and insecticidal properties. The results showed that chitosan significantly reduced aphid colonisation and feeding preference, lowered infestation intensity, and enhanced natural predation. Furthermore, chitosan treatments suppressed aphid reproduction, prolonged the aphid life cycle, and decreased their growth rate. The direct spray method was found to be more effective than the systemic application. Among the treatments, KK 0.9 consistently produced the most favourable outcomes across all parameters, indicating its potential as an effective bio-insecticidal agent for pest and disease management in yard-long bean cultivation.

Abstract

Tobacco (Nicotiana tabacum L.) is an important agricultural product in Indonesia. Disease information on tobacco is required to develop effective control methods for supporting a proper tobacco farming system. This study investigates the disease type and intensity of tobacco in monoculture and polyculture cropping systems in Patebon District, Kendal Regency, Central Java. Disease evaluation factors such as types of symptoms, disease incidence and severity, and crop productivity under both crop systems were measured on tobacco every week for four weeks from 14 to 17 weeks after planting, as well as during harvest. Microscopic observation was used to identify the causative infections. The findings revealed that the disease makeup differed amongst crop systems. The leaf curl (Tobacco leaf curl virus) and mosaic (Tobacco mosaic virus) diseases were discovered in both cropping systems. However, anthracnose (Colletotrichum sp.) and leaf spot (Cladosporium sp.) were only observed in monoculture farming systems, whereas wildfire (Pseudomonas syringae pv. tabaci) was only identified in polyculture farming systems at a low incidence. In general, disease incidence and severity were higher in monoculture agriculture systems than in polyculture crops. Furthermore, the policulture crop system had a slightly higher yield, indicating that tobacco would be better planted in polyculture than monoculture crop systems.

Abstract

One solution to solve the problem of low maize productivity in dry land is to develop superior maize varieties with high production characteristics and resistance to drought stress.  This study aims to evaluate the characteristics of 10 hybrid maize candidates with high production characteristics and resistance to drought stress.The research used a Randomized Complete Block Design (RCBD) with 13 genotypes (10 hybrid maize candidates, three comparison varieties (Jakaring, Pioneer-X, and Bisi-X) as treatments and was repeated three times, so that there were 39 experimental units.Drought stress research follows the CIMMYT method. The observation parameters in this study were plant height, stem diameter, number of leaves, leaf length, leaf area, ear height, days of 50% tasseling, days to 50% silking, harvest age, number of kernel rows, weight of cob with husk, ear length, ear diameter, kernel width, kernel length, kernel thickness, 1000-kernel weight, and production per hectare. The results of the variance analysis showed that several genotypes tested had a significant effect on the characters of plant height, stem diameter, number of leaves, leaf length, leaf area, ear height, days of 50% tasseling, days to 50% silking, harvest age, number of kernel rows, weight of cob with husk, ear length, ear diameter, kernel width, kernel thickness, 1000-kernel weight, and production per hectare.  The value of heritability in the broad sense of candidate maize for all evaluated characters ranged from 0.00-97.64. The character of production per hectare significantly correlates with the ear length and ear diameter, with respective correlation coefficient values of 0.36 and 0.56.  The character of the ear height had a significant negative correlation with the production per hectare character, with a correlation coefficient value of -0.39.  The selected genotypes in releasing hybrid varieties were G1, G2, G3, G4, and G6.

Abstract

Groundnut (Arachis hypogaea L.) is one of the food crops that has high economic value. However, one of the constraints to groundnut production is the stem base rot (Sclerotium rolfsii) and rust (Puccinia arachidis) diseases. Liquid smoke is known to have antimicrobial activities that need to be further studied for their potential to control various types of pathogens. This study aimed to test the ability of liquid smoke from empty palm bunches in controlling S. rolfsii and P. arachidis in vitro. The phytotoxicity of liquid smoke to seeds was tested using a rolled paper test established in plastic. Antimicrobial activity was tested by using the poisoning medium method against S. rolfsii, while spore germination test against P. arachidis was conducted by direct liquid smoke dripping onto uredospore on object glass. Antimicrobial activity of liquid smoke at concentrations of 0.1%, 0.5%, 1.0%, 1.2%, and 1.4% showed growth inhibition of S. rolfsii by 2.0%, 5.4%, 35.0%, 78.8%, and 100%, respectively. At 24 hours after treatment, the effect of liquid smoke on P. arachidis spore germination at concentrations of 0.1% and 1.0% was 1.7% and 0.0% when compared to the control, 8.4%, and at 48 hours after treatment was 1.5% and 0.0% compared to the control, 9.7%. It indicates the ability of liquid smoke as an antifungal.
