Abstract

The purpose of this study is to increase the propagation success rate of Rosa centifolia L. cuttings by examining the interaction of several types of growing media with varying amounts of auxin-based plant growth regulators. A factorial Completely Randomized Design with four treatment groups and three replications. The first factor was the composition of the planting media, which was made up of four tiers of soil: soil:husk (1:1), soil:compost (1:1), and soil:manure (1:1). The second factor was the concentration of indole-3-butyric acid (IBA), which has four levels: Z1 (control), Z2 (500 ppm), Z3 (1000 ppm), and Z4 (1500 ppm). The acquired data were subjected to Analysis of Variance, which was followed by a comparison using the Least Significant Difference test to identify significant treatment effects. The results showed that the soil:compost (1:1) treatment was the most effective planting media composition in terms of shoot length, number of leaves, and flowering time. Providing auxin concentrations is not effective in increasing root growth and rose plant yield through cutting propagation. Keywords: auxin, flower appearance time, growing media, indole–3–butyric acid, rose cuttings

Abstract

The COVID-19 pandemic required new approaches to organizing regional elections, highlighting the use of information systems to reduce infection risk and improve election management effectiveness. This study examines the influence of information systems and political participation on the efficacy of simultaneous regional head elections during the pandemic. A quantitative design determined a sample of 402 respondents with the Slovin formula at a 95% confidence level. Data were collected through a Likert-scale questionnaire comprising 12 indicators of information systems, 21 of political participation, and 12 of electoral effectiveness, and analyzed using Structural Equation Modeling (SEM) with LISREL. The results show that information systems exerted a positive but statistically insignificant effect on electoral effectiveness (T-value = 0.79, below the 1.96 threshold). In contrast, political participation demonstrated a significant positive impact (T-value = 6.79), underscoring its decisive role in achieving effective election outcomes under pandemic conditions. These findings emphasize the importance of citizen engagement for sustaining democratic processes during public health crises and illustrate how digital technologies can support, but not replace, active political participation.

Abstract

Tomatoes are a popular commodity in Indonesia, with demand increasing every year. The lack of production compared to the demand for tomato commodities requires steps to increase production, one of which is by providing a booster in the form of a natural growth regulator. This study used a Split Plot Design (2x5) with a basic design of Randomized Group Design. The main plot was Tomato Plant Variety, which consisted of two types, namely Fortuna Variety and Servo F1 Variety. The subplots were natural growth regulators consisting of five types: Water, GA3 100 ppm, Sweet Corn Extract equivalent to 100 ppm GA3, Shallot Extract equivalent to 100 ppm, and Moringa Leaf Extract equivalent to 100 ppm GA3. The results showed that the Fortuna tomato variety gave the best results in the parameters of dry weight of biomass per plant and chlorophyll content, while the application of moringa leaf extract gave the best results in the parameter of leaf area.

Abstract

Introduction: Light-emitting diodes (LEDs) are artificial light sources that have been widely used in indoor farming systems. The light quality of red and blue LEDs plays a role in plant growth and diverse physiological responses. The right ratio of red and blue LEDs is expected to increase the growth, yield and physiology of Pakchoy plants. Experiments on the effect of LED light quality on growth, yield and physiology of Pakchoy plants have been carried out at the Grow Box. Methods: The experiment was arranged in a Completely Randomized Design (CRD) consisting of 5 types of LED light quality, with the ratio of Red and Blue light (R:B), namely: (R10), (B10), (R5:B5), (R3:B7) , and (R7:B3). Each treatment was repeated 3 times, so there were 15 experimental units. Parameters observed included growth, yield and physiological components related to photosynthesis, namely: plant height (cm), plant length (cm), number of leaves (plant-1), leaf area (cm2), plant fresh weight (g plants -1), content of chlorophyll a, b and total (mg g-1), leaf carotenoids content (mg g-1), chlorophyll content of SPAD (Soil Plant Analysis Development), and DCGI (Dark Color Green Index). Results: The light quality of monochromatic blue LEDs (B10) and the combination of red and blue (R3:B7, R5:B5 and R7:B3) significantly improves vegetative growth, chlorophyll content, carotenoids and fresh weight than monochromatic red light (R10). Monochromatic red light R10 decreased growth, chlorophyll component and yield in Pakchoy plants. Conclusion: Red and blue LEDs with a ratio of R3:B7 showed the best results on all observation parameters.

Abstract

This study aims to explore the role and contribution of Street Vendors (PKL) in local economic development. Through data collection from 50 respondents involved in PKL activities, analysis was conducted on demographic characteristics, types of products sold, and daily earnings of the vendors. The results show that the majority of respondents are within the productive age range (27-40 years), predominantly male, with educational backgrounds of SMP (junior high school) and SD (elementary school), and an average trading experience between 2 to 5 years. The most sold products are food, with 95% of respondents contributing to the local economy by paying retribution when trading in places that require an entrance fee. Validity testing of the questionnaire indicates that all questions are well-measured, while reliability testing yields values above 0.7, indicating that the research instrument is reliable. Moreover, frequency analysis shows that 60% of respondents are food traders, with an Independent Samples T-Test revealing that the average daily earnings of food vendors reach Rp 250,000, while non-food vendors average only Rp 180,000, indicating a significant difference. This research emphasizes the important role of PKL in creating jobs, increasing community income, and contributing to local economic sustainability, and is expected to provide insights for decision-making in policies that support the development of the informal sector and the improvement of community welfare.

Abstract

Cherry tomatoes have high economic value, but their production is low, this is due to the low quality of seeds. Coating and storage are efforts made to maintain seed quality. This study aims to examine the effect of coating materials and shelf life on seed viability and cherry tomato growth. The experimental design used is Time Series with a long storage series and coating on seeds. The long storage consists of 4 levels; 0, 30, 60, and 90 days and the Coating Material consists of 4 levels; uncoating, PEG 6000, Arabic Gum, Galangal Powder, and Clove Oil with 3 replications. The data analyzed with Honest Real Difference Test. The results showed that Clove oil hasn’t effect the germination. Uncoated and unstored seeds have the highest moisture content. Plant height, number of leaves, fresh weight of the stamp, dry weight of the stamp, and flowering time have no effect, this is due to internal factors such as seed genetics and external factors such as the concentration of coating materials and plant growth environment.

Abstract

Farmer welfare is indicated by the level of purchasing power, which is calculated based on the ratio between the price index received from agricultural products and the price index paid for household consumption and production inputs. This study aims to analyze the internal and external factors influencing farmers’ welfare in Kutai Kartanegara Regency. The research data is primary and secondary data with a mixed method. The analysis was conducted using multiple linear regression to identify the factors that significantly affect farmers’ welfare. The results show that income, commodity prices, household consumption, and agricultural input costs are significant determinants of farmers’ welfare. Income and commodity prices have a positive effect, while agricultural input costs have a negative effect. The coefficient of determination (R²) values of 81.70% for the food crop subsector and 64.67% for the plantation subsector indicate that these variables explain a large portion of the variation in farmers’ welfare in the study area. Increased income increases welfare, but if consumption expenditure and input costs increase more than the increase in income, then farmer welfare will actually decrease. There is a need for policies to stabilize agricultural product prices, reduce production costs, and increase farmer productivity in Kutai Kartanegara Regency by strengthening market access, providing affordable inputs, and implementing technology and training so that agricultural products have added value and farmer welfare increases.
