Abstract

Chili commodity production has been rising and falling over the years. In contrast, prices for chili experience extreme variability. A price fluctuation of more than 40% indicates that something is wrong with supply management. Chili price volatility poses significant challenges for food security and inflation control in Indonesia. This study investigates the factors influencing cayenne pepper prices using daily data from January 2023 to September 2024 at the Kramat Jati Wholesale Market. An Autoregressive Distributed Lag (ARDL) model was applied to estimate the dynamic relationship between prices and supplies of cayenne and curly red chili. The results indicate that previous prices, substitution effects with curly red chili, and supply shocks have a significant influence on cayenne pepper prices. These findings underscore the importance of real-time supply monitoring, market integration, and strategic distribution planning in mitigating price spikes. The study offers empirical evidence to support more responsive government interventions in stabilizing chili prices and reducing inflationary pressure in perishable food markets.

Abstract

Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae) is a major stored product pest that can damage flour in storage. The infestation of T. confusum causes contamination of stored grain, such as flour. Research about the population growth of T. confusum in various commercial and non-commercial flours is still limited. This study aims to determine the population growth of T. confusum in various commercial and non-commercial flours. The study was conducted using the no-choice test method (NCTM). This study used a treatment jar containing 30 g of diet and infested 15 pairs of T. confusum adults for 7 days. Data obtained from this research were analyzed using analysis of variance (ANOVA) and further analyzed using the Duncan Multiple Range Test (DMRT) at a 5% significance level. The results showed that the number of larvae, pupae, and F1 progeny of T. confusum was higher in non-commercial red rice flour (80, 50 individuals; 59, 50 individuals; 57, 50 individuals) compared to other types of flour. The chemical characteristics of diets that can affect the population growth of T. confusum include fat, ash, carbohydrate, and phenol content. In conclusion, understanding the chemical characteristics of flour is crucial for developing a strategy to control T. confusum.

Abstract

The uniqueness of stingless bee honey makes it an attractive choice as both food and natural medicine for honey consumers, who were previously dominated by honey produced by honeybees (Apis mellifera). This study examines the marketing of stingless bee honey in North Sumatra. The objectives were to determine marketing channels and functions, farmer share, share margin, and the marketing mix. This study uses a cross-sectional survey in five districts/cities in North Sumatra. Respondents were selected using the purposive sampling method (11 stingless bee farmers with at least 50 colonies and at least 5 years of experience), snowball sampling (5 resellers) by recording buying and selling prices. The study results show that three marketing channels are used, with farmers sharing 64.6% on channel 2, yielding an average margin of IDR 106,088/kg. This study found that the longer the distribution chain, the smaller the proportion of income received by farmers (farmer share). Direct channels provide full margins to farmers, whereas the involvement of resellers significantly reduces the farmer's share of the profit. The implications of these findings underscore the importance of developing more efficient and equitable marketing strategies for farmers, including the effective use of digital platforms to expand their markets. However, this study was limited to a specific region and sample. Further studies are recommended to analyze channel efficiency and the impact of digital promotions on increasing sales and farmer welfare.

Abstract

Fusarium wilt caused by Fusarium oxysporum remains a major limitation in shallot (Allium cepa L.) cultivation, severely reducing yield and crop quality. This study aimed to evaluate the effectiveness of native rhizobacterial isolates as biological inducers of resistance against Fusarium wilt under different organic growing media. A split-plot randomized complete block design was applied using three growing media (rice husk charcoal, manure, and their combination) and four rhizobacterial treatments (control and three local isolates: R1–R3) with three replications. Key physiological assays included the measurement of salicylic acid (SA) content and peroxidase (POX) enzyme activity as biochemical indicators of induced resistance. Results showed that the isolate from Waitii Village (R3) significantly reduced disease incidence to 52.67% compared with 86.56% in the control, while the combined organic medium (M2) further enhanced plant resistance. Increased SA (26.82 ppm) and POX activity exhibited strong negative correlations with disease incidence (R² = 0.60 and R² = 0.71, respectively), indicating their pivotal role in rhizobacteria-mediated defense activation. These findings confirm that indigenous rhizobacteria, when combined with organic amendments, effectively stimulate systemic acquired resistance and mitigate the severity of Fusarium wilt in shallots. The study highlights the potential of the R3 isolate as a sustainable bioinoculant candidate for integrated disease management. Further molecular identification, in vitro antagonism testing, and multi-location field validation are recommended to ensure its stability, efficacy, and applicability under diverse agroecological conditions.

Abstract

. The increasing trend of fossil fuel consumption is inversely proportional to the available natural gas reserves. Renewable energy sources derived from biomass are needed to become alternative fuels, such as biobriquettes. This study aims to optimize biobriquette production by adding burning initiator materials to obtain the best composition that meets the Indonesian National Standard (SNI) and exhibits good ignition characteristics. The experimental design was based on the Taguchi method with an L9 (34) orthogonal array, and the results were statistically analyzed using Grey Relational Analysis (GRA) to evaluate multiple responses. Although the highest Grey Relational Grade (GRG) indicated the theoretical optimum, the confirmation test revealed a slightly different composition with better burning performance. The optimal composition consisted of 3 g of OPEFB (A1), 16 g of PKS (B2), 40% pine sap (C3), and 20% sulfur (D3), producing a moisture content of 1.148%, ash content of 10.75%, volatile matter content of 12.36%, calorific value of 7,223.5 cal‧g-1, initial ignition time of 1.83 s, and burning rate of 0.237 mg‧min-1. These results indicate that the produced biobriquettes meet SNI standards for moisture, volatile matter, calorific value, and have good burning ease.

Abstract

This greenhouse study investigated the impact of Biotogrow liquid organic fertilizer concentration and application frequency on lettuce (Lactuca sativa L.) growth and yield at Telaga Kodok from May to August 2024. The purpose of the research is to determine the effect of Biotogrow Liquid Fertiliser concentration and fertilisation interval, as well as the interaction between the two, on the growth and production of lettuce (Lactuca sativa L.). Using a factorial Randomized Complete Block Design with three replications, researchers tested four Biotogrow concentrations (0, 2, 5, and 8 ml L⁻¹) and four fertilization intervals (0, 4, 7, and 10 days). Growth parameters, including plant height, leaf number, leaf area, fresh weights, shoot-to-root ratio, and harvest index, were measured at 14, 21, 28, and 35 days after planting. ANOVA and Duncan's Multiple Range Test (α = 0.05) revealed significant findings. Biotogrow concentration substantially influenced plant height at 21, 28, and 35 DAP (P < 0.01), leaf number throughout all observation periods (P < 0.05 at 14 DAP; P < 0.01 thereafter), plus shoot and root fresh weight, leaf area, and harvest index (P < 0.01). Fertilization intervals significantly affected all parameters except the shoot-to-root ratio (P < 0.01). Importantly, concentration-interval interactions showed highly significant effects on leaf number at 35 DAP, shoot fresh weight, and leaf area (P < 0.01), with significant impacts on plant height at 28 and 35 DAP, leaf number at 28 DAP, and root fresh weight (P < 0.05). These results demonstrate that optimizing both Biotogrow concentration and application timing can significantly enhance lettuce productivity under greenhouse conditions.

Abstract

Healthy and sustainable diets play a crucial role in addressing global challenges, including climate change, food security, and public health. This study focuses on plant-based meatballs, analyzing their appeal as an environmentally friendly, resource-efficient, and healthy alternative protein source. Conducted among undergraduate students at Brawijaya University, the study examines the impact of innovation adoption characteristics on consumption intentions, with environmental concerns serving as a moderating factor. Utilizing an online survey distributed to 385 respondents, data were collected over two weeks in October 2024. Results reveal that plant-based meatballs received the highest average scores in compatibility (Attractiveness: 3.94, Safety: 3.81) and relative advantages (Environmentally Friendly: 3.84, Food Security: 3.28), as well as in consumption intention for Health Interest (3.88). Statistical analyses confirmed strong convergent validity, reliability, and predictive performance, with meatballs showing significant influence on consumption intention (f² = 0.839). This research highlights the strategic role of students as agents of change in promoting sustainable diets, providing actionable insights for developing marketing strategies and policies to support the adoption of plant-based alternatives. Emphasizing the environmental and health benefits of plant-based meatballs could drive their wider adoption and contribute to a more sustainable food system in Indonesia.

Abstract

Sweet corn is recognized as one of the plants with relatively high economic value and potential for expansion, increasing from 8.31 to 18 million tons. Arranging planting distance and applying potassium when conditions are stressed by drought can be one of the efforts to modify the environment for plant growth.  This study employed a split-plot design repeated three times, consisting of a main plot and three levels of sub-plots. The main plot is J1 = 75 x 20 cm, J2 = 50 x 30 cm, and J3 = 60 x 25 cm. While the sub-plots are K1 = 100 kg.ha-1, K2 = 200 kg.ha-1, dan K3 = 300 kg.ha-1. The results obtained show that the arrangement of closer planting distances between rows 60 x 25 cm with increasing doses of Potassium 200 kg.ha-1 results in an interaction with increased growth and optimal sweet corn yields. The microclimate conditions of sweet corn, including soil moisture, were influenced by spacing and potassium dosage. The relationship between plant distance and potassium dosage to soil moisture is directly proportional or linear. Plant distance of 60 x 25 cm with increasing potassium dose, such as at a potassium dose of 300 kg.ha-1 produces the most moist soil moisture under drought stress conditions.

Abstract

Local food is a viable alternative to traditional food sources for meeting people's food needs. Central Java Province is a fairly high producer of porang. This is proven. One location with many farmers growing porang is in the buffer district of Surakarta City, namely Sukoharjo Regency. The production of food crops, especially porang in Sukoharjo, is what actually provides supplies to urban areas. Porang plants are sold in processed form, such as flour. The added value of this product increases economic value. The purpose of this study is to reveal the strengthening of the porang creative economy in Central Java Province through the creation of value-added products and the introduction of a communal business system that could potentially encourage porang production to become one of the iconic products in Central Java. This study uses a descriptive analytical method. This study utilizes primary data collected through direct interviews with farmers. The respondents of this study were 50 porang farmers in Sukoharjo Regency who are members of the Sukoharjo Porang Farmers' Friends (SPPS) in Kamal Village, Bulu District, Sukoharjo Regency. Data analysis used the Hayami method of value-added analysis and a literature review of the communal introduction system. The value-added analysis results show that glucomannan flour production generates an added value of IDR 199,641 per kg of porang tuber raw material with a ratio of 72.25%. The profit obtained by the trading business is IDR. 186,483 per kilogram of porang tuber raw material with a profit ratio of 68.68%. The communal introduction system enables the porang business to be well-managed, as there are still porang farmers outside Sukoharjo Regency who continue to plant. Communal integration can stabilize production supplies, thereby strengthening existing institutions and necessitating testing in the three districts involved.

Abstract

Organic waste is an abundant resource but remains underutilized as a safe and nutrient-rich organic fertilizer. This study aims to evaluate the effectiveness of Trichoderma as an alternative bioactivator to EM4 in improving the quality of liquid organic fertilizer (LOF) and compost through tiered bucket systems under aerobic (A2) and anaerobic (A1) conditions. A randomized complete block design was used with five Trichoderma doses (0; 15; 20; 25; 30 mL.L⁻¹) and EM4 (30 mL.L⁻¹) as a comparison. The liquid and solid fractions were analyzed for C, N, C/N ratio, P₂O₅, K₂O, and heavy metals (Pb, Cd, Cu) using standard methods. The data were analyzed through ANOVA and orthogonal contrast tests. Results showed that the aerobic system consistently reduced the C/N ratio, producing more mature and stable products, while the anaerobic system tended to retain higher C-organic content. These differences were statistically significant as the aerobic condition (A2) decreased the C/N ratio by 4.74 or 40.93% in liquid organic fertilizer and by 3.62 or 19.52% in compost compared to the anaerobic condition (A1), while total P₂O₅ in liquid organic fertilizer increased by about 14.81% under A2. Medium–high doses of Trichoderma (25–30 mL L⁻¹) in the aerobic system yielded the best quality in terms of maturity, whereas EM4 generally resulted in higher macro-nutrient contents (N, P₂O₅, K₂O). All heavy metal levels were far below the SNI/Ministry of Agriculture thresholds, indicating product safety. Practically, the A2–T3/T4 combination is recommended to produce mature, stable, and safe organic fertilizer, while co-inoculation strategies may be pursued to enhance nutrient content. This study confirms that Trichoderma primarily accelerates humification and stabilizes organic matter, offering a practical, low-cost option for household/community organic waste management within a circular-economy framework; accordingly, the aerobic bucket system with medium–high Trichoderma doses (A2–T3/T4) is recommended to achieve mature, stable LOF–compost. However, the findings are lab-scale and substrate-specific.
