Abstract

Moler disease caused by Fusarium oxysporum f. sp. cepae is a main disease on shallot resulting high yield loss and always found in every shallot plantation. Biological control using antagonistic microorganism is an effective method in controlling moler disease with the mode of action of induced resistance. Expression of induced resistance may be affected by several factors such as the concentration of inducer. This research studied the effect of concentration of inducer in increasing induced resistance of shallot to moler disease so that the best contration was revealed. Single factor (spore concentration) with Completely Randomized Design and three replications was used. Spore concentration of avirulent F. oxyssporum f. sp. cepae used in this research was as follows: A = control, B = spore concentration of 104/ml, C = spore concentration of 105/ml, and D = spore concentration of 106/ml. Induced resistance was raised by soaking the shallot bulbs in the spore suspension of the inducer for about 30 minutes. The bulbs were then planted in polybags containing planting media of soil : cow manure with the ration of 1:1 (v/v). The results showed that the treatments were able to increase shallot resistance to moler disease from susceptible to moderate. Regression analysis revealed that the higher the concentration the higher the suppression of moler disease intensity. Increasing suppression of moler disease intensity may increase the growth and yield of shallot.

Abstract

Issues surrounding hybrid corn seeds in Indonesia include the increasing demand for seeds from year to year and the limited selection of hybrid varieties on the market. One solution to reduce the problem of hybrid corn seed availability is to develop new strains or varieties using parent plants from local areas. Polinela corn breeders have currently developed several hybrid corn lines (F1) that need to be tested for performance. The objective of this study was to determine the performance advantages of five Polinela hybrid corn lines compared to five superior commercial hybrid corn varieties developed by several multinational companies. The study was designed using a completely randomized block design (CRBD). The treatments used were five Polinela hybrid corn lines and five commercial hybrid corn varieties. The observations included quantitative yield components and yield potential, as well as several qualitative characteristics of the lines and varieties. The results showed that there were three new hybrid lines, namely line PL 401/PL 20, line PL.401/PL.2020, and line PL 202/PL 40), which had yield potential equivalent to the hybrid varieties BISI 18, NK 22, and Pertiwi 3, with a dry grain yield potential of between 11.7 and 12.9 tons.ha-1. There are three new hybrid corn lines with grain yield potential equivalent to three commercial varieties and higher than two comparison varieties, namely Pioneer 88 and Pertiwi 6.

Abstract

The utilization of vegetable waste as a raw material for liquid organic fertilizer (LOF) is an eco-friendly innovation that can enhance soil fertility and plant growth. This study aims to evaluate the effectiveness of LOF derived from vegetable waste from Banyuasri Market, Buleleng Regency, on the growth of shallots (Allium cepa). The study employed a Completely Randomized Design (CRD) with three treatments: Formula A (liquid concentration at 2 ml/L), Formula B (liquid concentration at 5 mL/L), and a control group (without LOF). The observed parameters included leaf length and the number of leaves over a six-week observation period. The results showed that LOF treatments (Formula A and B) led to better shallot growth compared to the control group. The average leaf length in Formula A reached 45 cm, Formula B 40 cm, while the control group only achieved 30 cm. Similarly, the number of leaves followed the same trend, with Formula A producing approximately 20 leaves, Formula B 18-19 leaves, and the control group only 15 leaves. These findings indicate that LOF derived from vegetable waste significantly enhances the vegetative growth of shallots compared to plants that did not receive additional treatment. In conclusion, the application of LOF from vegetable waste can serve as an effective organic fertilizer alternative to improve shallot growth with best concentration at 5 mL/L. The use of LOF from vegetable waste also has the potential to reduce environmental pollution while promoting sustainable agricultural productivity.

Abstract

Tissue culture can be used as an alternative technique that can be used to multiply porang seeds to meet the need for seeds in porang development. This study aims to determine the proliferation response of porang in various types and concentrations of BAP or TDZ. The experiment was carried out using a randomized block design (RAK). The treatments tried in the shoot proliferation experiment were P1 (MS 0), P2 (BAP 0.5 mg.l-1), P3 (BAP 1 mg.l-1), P4 (TDZ 0.5 mg.l-1) and P5 (TDZ 1 mg.l-1). Each treatment was tried with 5 replications, and each treatment per replication was planted with 5 bottles. Data were analyzed by Analysis of Variance, and differences between treatments were seen by the LSD test at the 5% level. The use of MS 0 and BAP 1 mg.l-1 gave better results compared to other treatments. The use of MS 0 and BAP 1 mg.l-1 resulted in 100% shoot growth on porang propagules. MS 0 and BAP 1 mg.l-1 produced the highest number of shoots (17.8 and 17.4) and the highest shoot height (3.52 and 2.50) compared to the other three treatments.

Abstract

Inceptisols are widely distributed in tropical regions, including Indonesia, and are characterized by high rainfall and intensive weathering. These conditions promote severe nutrient leaching, low cation exchange capacity (CEC), and moderately to slightly acidic soil pH, thereby limiting nutrient availability, fertilizer-use efficiency, and crop productivity, particularly in oil palm (Elaeis guineensis) plantations. This study aimed to evaluate the effects of BIO SOLID 17, an organic soil conditioner derived from palm oil mill effluent (POME) sludge, on the chemical and physical properties of Inceptisol through a controlled incubation experiment. A two-month laboratory incubation was conducted using a randomized complete block design with five application rates of BIO SOLID 17 (0, 5, 10, 15, and 20 kg ha⁻¹), each with five replications. Observed parameters included soil pH, cation exchange capacity (CEC), and water-holding capacity (WHC), which were analyzed using standard methods. The results demonstrated that BIO SOLID 17 application significantly improved Inceptisol soil quality in a dose-dependent manner. Soil pH increased from strongly acidic conditions (4.85) in the control to near-neutral levels (6.19) at the highest application rate. Soil CEC also increased significantly from 34.41 to 47.49 cmolc kg⁻¹, indicating enhanced nutrient retention capacity. In addition, soil water-holding capacity increased from 46.82% to 55.81%, reflecting improvements in soil aggregation and moisture retention. Overall, BIO SOLID 17 shows strong potential as a sustainable organic soil amendment for improving the chemical and physical fertility of Inceptisol. The utilization of POME-based materials supports circular economy principles by converting agro-industrial waste into value-added agricultural inputs. Further field-scale studies are recommended to confirm effectiveness and determine optimal application rates under oil palm plantation systems.

Abstract

The limited availability of conventional porang seedlings through seeds and tubers is a constraint in the development of this plant because it is time-consuming, seasonal-dependent, and produces non-uniform seedlings. Therefore, an alternative method in the form of tissue culture, known as micropropagation, is needed to produce quality porang seedlings. Micropropagation is a more efficient and profitable plant propagation method than conventional methods because it can produce seedlings in a relatively short time, is not seasonal-dependent, uniform, and free from pathogens. This study aims to determine the response of porang shoot multiplication to various types and concentrations of cytokinin growth regulators. The experiment was conducted using randomized block design. The treatments tested were P1 : BAP 0 mg.l-1 + TDZ 1 mg.l-1 ; P2 : BAP 0 mg.l-1 + TDZ 2 mg.l-1 ; P3 : BAP 0 mg.l-1 + TDZ 3 mg.l-1 ; P4 : BAP 1 mg.l-1 + TDZ 0 mg.l-1 ; P5 : BAP 1 mg.l-1 + TDZ 0,5 mg.l-1 ; P6 : BAP 1 mg.l-1 + TDZ 1 mg.l-1 ; P7 : BAP 2 mg.l-1 + TDZ 0 mg.l-1 ; P8 : BAP 2 mg.l-1 + TDZ 0,5 mg.l-1 ; P9 : BAP 2 mg.l-1 + TDZ 1 mg.l-1 ; P10 : BAP 3 mg.l-1 + TDZ 0 mg.l-1 ; P11 : BAP 3 mg.l-1 + TDZ 0,5 mg.l-1 ; dan P12 : BAP 3 mg.l-1 + TDZ 1 mg.l-1. Each treatment was replicated five times, with five bottles planted in each replication. Data were analyzed using Analysis of Variance, and differences between treatments were assessed using the LSD test at the 5% level. The observed variables were the rate at which explants formed buds, the number of buds, and the multiplication rate. Addition of cytokinin affected the multiplication response of porang buds in vitro. The P6 treatment produced the fastest bud formation rate, the highest number of buds and the highest multiplication rate.

Abstract

Rice is an agricultural commodity that plays an important role in meeting the basic needs of people in Indonesia. Along with population growth, rice consumption in Indonesia continues to increase. However, the availability of agricultural land is not commensurate with the increase in population, on the contrary, its availability is decreasing. One way to increase rice productivity is land intensification through improvements in the management of production factors by using them efficiently. This research aims to determine: 1) the determining factors for rice farming production, 2) the determining factors for technical efficiency and technical inefficiency of rice farming in the Special Region of Yogyakarta (DIY). The data used is secondary data sourced from the results of the 2013 agricultural census with a sample of 3,751 farmers. Data analysis uses the multiple linear regression method estimated using Ordinary Least Square (OLS) to determine the determining factors of rice farming production. Technical efficiency is analyzed using a stochastic frontier model estimated with Maximum Likelihood Estimation (MLE). Based on the results of the analysis, it is known that rice farming production in DIY is influenced by harvest area, NPK fertilizer, organic fertilizer, pesticides, labor, irrigation systems, superior varieties, seasons and climate change. Factors that have a significant influence on the technical efficiency of rice farming are harvest area, NPK fertilizer, organic fertilizer, labor, irrigation systems, superior seeds and pesticides. The determining factors for technical inefficiency are age, education, government assistance, counseling, and field schools.

Abstract

Air quality and soil fertility are critical factors for sustaining agricultural productivity. This study, conducted in Kebontunggul Village from July to September 2025, evaluated ambient air quality and soil fertility at two distinct sites. Results indicated that major air pollutants such as SO₂, NO₂, O₃, and CO remained below permissible limits, suggesting relatively safe conditions, though variations in NH₃, Pb, and TSP highlight potential long-term risks requiring monitoring. Soil analysis revealed contrasting characteristics: Site 1 had low available phosphorus (4.20 mg/kg) but higher organic carbon (3.36%), while Site 2 showed higher phosphorus (7.24 mg/kg) yet lower organic carbon (2.85%). These findings underscore the need for site-specific management strategies, with organic inputs prioritized at Site 2 and phosphorus fertilization emphasized at Site 1 to enhance productivity while maintaining agricultural sustainability.

Abstract

 Trichoderma brevicompactum indigenous to Gorontalo is a potential biological control agent that plays an important role in plant disease management and agricultural waste utilization. The availability of cost-effective and environmentally friendly growth media is a key factor in supporting the production of fungal inoculum. This study aimed to describe the growth response of Gorontalo indigenous T. brevicompactum on agricultural waste-based media, namely cassava peel extract and coffee peel extract, in comparison with Potato Dextrose Broth (PDB) as a control medium. The study was conducted using a descriptive approach at the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, Universitas Negeri Gorontalo. The observed parameters included changes in the physical properties of the media (temperature, pH, and color), mycelial biomass, relative growth rate (RGR), absolute growth rate (AGR), and conidial density during the incubation period. The results showed that, descriptively, cassava peel extract exhibited a higher tendency in RGR and AGR values than the control medium and coffee peel extract, particularly during the mid-incubation phase. In contrast, coffee peel extract showed a relatively lower growth response, especially at the later incubation stage. Conidial density increased over time in all media, with the highest values observed in the control medium, followed by cassava peel extract and coffee peel extract. Overall, cassava peel and coffee peel wastes have potential as alternative growth media for T. brevicompactum, with cassava peel extract demonstrating a more favorable growth tendency.
