Abstract

This study aimed to investigate the effect of various doses of gamma radiation (60Co) on the germination of Prentul chili pepper.  This research was conducted at the experimental field or greenhouse of the University of 17 August 1945, Banyuwangi, from August to September 2025. This study employed an RCBD with a single factor, namely the dose of ??Co gamma radiation. The treatment consisted of 11 radiation dose levels: 0 Gy (control), 50, 100, 150, 200, 250, 300, 350, 400, 450, and 500 Gy. The data obtained were analyzed using analysis of variance (ANOVA) to determine the effect of radiation dose on each parameter. If significant differences were found, further analysis was conducted using Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Co-60 gamma radiation significantly affected the viability, mortality, germination rate (MGT), and early growth of prentul cayenne pepper seedlings. Low to moderate doses (50–200 Gy) reduced viability, whereas moderate doses (250–400 Gy) had a stimulatory effect similar to the control. The highest mortality occurred at a dose of 200 Gy, which is close to the LD??, thus potentially generating genetic diversity. At high doses (>400 Gy), MGT increased sharply, and seedling growth was severely inhibited by physiological damage. Thus, the dose range of 200–300 Gy can be considered the optimum dose for mutation induction in prentul cayenne pepper.

Abstract

Cattle fattening is an important livelihood for rural farmers in Indonesia, particularly in regions such as Pidie District, where small-scale livestock management contributes significantly to household income. However, limited capital, traditional management practices, and lack of economic feasibility information often hinder farmers from optimizing their productivity and profit. This study aims to analyze the profitability and feasibility of the cattle fattening business operated by the Blang Rimeh Farmers Group in Pulo Seunong Village, Tangse Subdistrict, Pidie Regency, as a basis for determining whether the business is viable for further development. The research was conducted from March to April 2024 using a survey approach with a census of all 11 group members as respondents. Data were collected through observation, interviews, and questionnaires. Profitability analysis was calculated using the income formula (? = TR ? TC), while feasibility was assessed through the Revenue/Cost (R/C) ratio and Return on Investment (ROI). The cattle fattening activities were found to be traditional in scale, with each farmer raising an average of one head and relying solely on fresh forage without the use of concentrate supplementation. The analysis revealed an average income of IDR 2,096,061 per person per period, a return on capital (R/C) ratio of 1.11, and an ROI of 11%. These values suggest that, despite the simplicity of management practices, the business generates a positive return and provides significant financial benefits to farmers.The cattle fattening business in the Blang Rimeh Farmers Group is profitable and feasible to pursue. Strengthening feeding management, improving facilities, and enhancing technical knowledge may further increase productivity and profitability.

Abstract

The success of oil palm cultivation is closely related to the quality of seedlings produced in the nursery phase. This study evaluated the potential acceleration of early growth in oil palm seedlings by optimizing biochar-based growing media combined with organic–inorganic fertilizer formulations. The experiment was arranged in a Completely Randomized Design (CRD) with three treatments: M1 (10 g urea + 50 g organic fertilizer), M2 (10 g NPK + 50 g organic fertilizer), and M3 (10 g urea + 10 g NPK). Each treatment was replicated ten times, resulting in 30 seedlings per replicate. Growth observations were conducted weekly from week 4 to week 20 (approximately four months), covering seedling height, leaf number, and stem diameter. Data were analyzed using one-way ANOVA at a 5% significance level, complemented by effect size analysis (?² and ?²) at week 20 to quantify the biological treatment's influence, and descriptive evaluation of the growth trend. The results showed no significant differences among treatments (p > 0.05). However, all treatments exceeded the physiological growth standards for four-month-old seedlings. M3 produced the highest growth response, with relative increases of 200% in height, 177.8% in leaf number, and 133.3% in stem diameter compared with the standard. These findings suggest that biochar-based growing media, combined with integrated organic-inorganic fertilizer formulations, can enhance early vegetative growth, although statistical significance has not yet been achieved within four months. Further observation up to ten months is recommended to validate the consistency of this growth acceleration.

Abstract

Peanut (Arachis hypogaea L.) is a valuable legume crop whose productivity depends on effective and environmentally friendly nutrient management. Eco-enzyme, a liquid organic product obtained from the fermentation of organic waste, has potential as a sustainable agricultural input; however, information regarding its optimal dosage and application method for peanut cultivation remains limited. This study aimed to evaluate the effects of eco-enzyme dosage, application method, and their interaction on the growth and yield components of peanut plants. The experiment was conducted using a factorial randomized block design with two factors. The first factor was eco-enzyme dosage at four levels: 0, 10, 15, and 20 mL plant?¹. The second factor was the application method, consisting of soil drenching and foliar spraying. Observations included vegetative growth parameters and yield components. Data were analyzed using analysis of variance (ANOVA) followed by a least significant difference test at the 5% level. The results showed that the eco-enzyme dosage significantly affected plant height at 30 and 45 days after planting, whereas the application method alone did not significantly influence most of the observed variables. However, a significant interaction between dosage and application method was observed for plant height at 45 days after planting, number of empty pods, fresh pod weight, dry pod weight, and seed weight. Higher eco-enzyme dosages combined with appropriate application methods tended to improve yield performance. In conclusion, eco-enzyme influenced peanut growth and yield selectively, and its effectiveness depended largely on the interaction between dosage and application method

Abstract

The rose flower, as a commodity widely cultivated in Musuk District, possesses great potential to boost both regional and local economies. Despite the significant potential of rose flowers, it has not yet been optimized by the community and government. The lack of community knowledge regarding the existing potential is one of the factors contributing to the suboptimal production of these rose flowers. The aim of this research is to identify the potential of rose flowers and analyze strategies for developing the existing rose flower potential in Musuk District. The method used in this research is a descriptive qualitative approach. Informant selection technique utilized snowball sampling. SWOT analysis was the analytical method employed to determine the condition of the rose flower potential and to formulate strategies for its development and economic improvement. The SWOT analysis results indicate that the rose flower potential is in Quadrant V, suggesting that the rose flower is in a stable condition but lacks a strong competitive advantage. Strategies to optimize the rose flower potential include diversifying rose flower products, expanding the market, and conducting replanting to rejuvenate old rose plants to increase production. Efforts to enhance the economy through rose flower potential involve product diversification into items like rose chips, rose tea, rose syrup, and rose water.

Abstract

This study aimed to compare the quality of Batu 55 tangerine (Citrus reticulata Blanco) fruit cultivated at PT. Kusuma Satria Dinasari Wisatajaya (Kusuma Agrowisata), Batu City, East Java, with the quality description of the national superior variety as stipulated in the Decree of the Minister of Agriculture No. 307/Kpts/SR.120/4/2006. The research was conducted for approximately four months, from September to November 2025, using a comparative research approach. Plant sampling was carried out using a systematic sampling method, involving 23 sample trees selected from a total population of 150 trees in Block A2. The observed variables included the number of fruits per tree, fruit diameter, fruit weight per fruit, and fruit sweetness level (% Brix). Compost fertilizer was applied at a dosage of 30 kg per tree as the cultivation treatment. The collected data were analyzed comparatively by contrasting field observation results with the official quality standards of the Batu 55 tangerine variety. The results indicated that compost application improved several physical quality attributes of Batu 55 tangerine fruit, particularly the number of fruits per tree, fruit diameter, and fruit weight, while the fruit sweetness level did not reach the standard value. Overall, the fruit quality generally met the characteristics of the superior variety, although variations were influenced by environmental conditions and cultivation practices. This study provides useful information for evaluating fruit quality and supporting sustainable cultivation of Batu 55 tangerines.
