Melakukan evaluasi pengaruh pupuk kandang ayam dan NPKMg terhadap produktivitas tanaman aren. Sugar palm (Arenga pinnata Merr.) is a plantation commodity that is very beneficial ecologically and financially because it can adapt to various geographical conditions such as mountains, valleys, riverbanks, and undulating land. However, the development of this plant is still constrained by low cultivation intensification, unstructured planting patterns, and optimal land use, resulting in low productivity. Increasing the productivity of sugar palm plants can be achieved through intensive cultivation. The purpose of this study was to study how chicken manure and NPKMg fertilizer affect the growth of sugar palm plants and determine the best fertilizer dosage.

Abstract

This study aimed to determine the effectiveness of fertilization application techniques and fertilization intervals on the growth of ornamental caladium (Caladium sp.). The research was conducted using a factorial randomized block design consisting of two factors, namely fertilization application techniques and fertilization intervals. The fertilization application techniques included spraying, drenching, and broadcasting, while the fertilization intervals consisted of once a week, once every two weeks, and once every three weeks. Observed parameters included plant height, number of leaves, leaf area, and root length. The results showed that fertilization application techniques significantly affected plant height, number of leaves, and leaf area, with the best treatment being the drenching technique. Fertilization intervals had a significant effect on the number of leaves, with the best result obtained from fertilization applied once a week. There was a significant interaction between fertilization application techniques and fertilization intervals on the number of leaves, with the best combination being drenching application and weekly fertilization. Therefore, the drenching fertilization technique combined with a one-week interval is recommended to enhance the growth of ornamental caladium plants.

Abstract

Land suitability evaluation is essential for optimizing maize (Zea mays L.) cultivation in dryland agricultural areas. This study aimed to evaluate the actual and potential land suitability classes for maize cultivation in Slogohimo District, Central Java, and to formulate appropriate land management strategies. The research employed a descriptive-explorative method using the Land Mapping Unit (LMU) approach combined with field observations. LMUs were delineated through integration of soil type and slope class maps, followed by suitability evaluation using the matching method. The results showed that actual land suitability varied across the study area, and no land was classified as Highly Suitable (S1). Potential land suitability in LMU 1, 3, and 4 was classified as Marginally Suitable (S3) with limiting factors including water availability (wa), nutrient retention (nr), and erosion hazard (eh). Meanwhile, LMU 1 and 5 were classified as Not Suitable (N) due to steep slopes (>25%) and shallow soil depth. Improvement scenarios involving organic matter application, liming, and soil conservation practices increased the potential suitability of LMU 3 and 4 to Moderately Suitable (S2). These findings provide important information for sustainable land management for maize cultivation in Slogohimo District.

Abstract

Agricultural extension plays an important role in improving farmers’ knowledge, attitudes, and skills through effective communication. However, extension activities still face challenges, including low meeting intensity, irregular activities, and limited interaction between extension workers and farmers, which may affect communication effectiveness within farmer groups. This study aimed to analyze the effect of extension frequency on communication effectiveness among farmer groups. A quantitative approach was employed in farmer groups in Sukabumi Regency, West Java, Indonesia, involving 30 respondents selected through purposive sampling. Data were collected using a Likert-scale questionnaire that had been tested for validity and reliability and were analyzed using simple linear regression with SPSS. The results showed that extension frequency had a positive and significant effect on communication effectiveness, with a significance value of 0.030 (<0.05) and a regression coefficient of 0.260. Higher extension frequency improved message comprehension, feedback, communication openness, and farmers’ attitudes. Therefore, increasing the frequency of extension activities should be supported by appropriate communication methods to optimize information delivery to farmers.

Abstract

Fermented beverages are increasingly viewed as business opportunities, but positive market perceptions do not always translate into entrepreneurial readiness. This study identified consumer-perceived dimensions of business potential and development barriers for fermented beverages. A quantitative survey was conducted in 2025 with 121 consumers in Java aged 17-30, 31-50, and over 50 years. Respondents had consumed at least one fermented beverage and completed a structured questionnaire through face-to-face assistance using Google Forms. Data were analyzed using descriptive statistics and principal component analysis with Varimax rotation. Business potential formed two factors explaining 75.016% of variance: market potential and product substitution capacity, and entrepreneurial and investment attractiveness. The market/substitution factor had a higher mean (3.438) than entrepreneurial/investment attractiveness (3.102). Development barriers formed two factors explaining 78.399% of variance: accessibility and market acceptance barriers, and technical production barriers. Technical production barriers had a higher mean (3.479) than accessibility/market acceptance (2.781). These findings indicate that consumers recognize fermented beverages as promising products, especially as alternatives to sugar-sweetened beverages, but are less ready to start or invest in the business. Business development should combine market expansion with technical training, simplified procedures, input access, food safety guidance, financing, and marketing support.

Abstract

Processed corn products have potential as value-added food products, but their development depends on consumer behavior and its influencing factors. This study aimed to describe consumer behavior toward processed corn products and analyze the factors affecting it. The research was conducted in Jatinangor District from January to February 2026 using a quantitative survey method. A total of 102 respondents were selected using purposive sampling, with the criteria of knowing or having consumed processed corn products. Data were collected using a five-point Likert scale questionnaire and analyzed using descriptive statistics and multiple linear regression. The results showed that consumer behavior was in the moderate-to-high category. The regression model had an R Square of 0.354, indicating that the independent variables explained 35.4% of consumer behavior variation. Price, promotion, product availability, family or friend influence, stress or fatigue, practicality, social media, age, and urban residence significantly affected consumer behavior. Social media had the largest positive coefficient, suggesting its key role in encouraging consumer behavior. The findings recommend strengthening digital promotion, product accessibility, practical packaging, and competitive pricing.

Abstract

PT Kartel Daun International cultivates, hybridizes, and markets ornamental Anthurium, but its domestic sales remain volatile. This study described the marketing system, identified factors associated with domestic demand, and formulated development strategies. A qualitative case study involved 12 informants from management, operational and sales staff, and domestic consumers. Data from in-depth interviews, observation, and documentation were validated through source and technique triangulation, then analyzed inductively using NVivo and qualitative SWOT. The company applied hybrid marketing through social media, marketplaces, websites, live sales, and greenhouse visits, supported by barcode, SKU, and RFID inventory systems. Domestic demand was associated with consumer knowledge, price perception, purchasing experience, substitute products, purchasing power, and preferences for unique plant characteristics. Collectors evaluated price relative to rarity, leaf form, verified identity, and service quality. The proposed strategies comprise localized sales channels and payment methods, entry-level product segmentation, and value-based communication to broaden the domestic market while preserving premium positioning.

Abstract

Seed dormancy is one of the factors limiting the production of local Bangka cayenne pepper seeds. The application of potassium nitrate (KNO₃) and soaking duration are reported to be effective in breaking seed dormancy, including in cayenne pepper seeds. This study aimed to determine the effective KNO₃ concentration and soaking duration for breaking seed dormancy in local Bangka cayenne pepper. This study was conducted at the Agricultural Laboratory of the Faculty of Agriculture, Fisheries, and Marine Sciences, Bangka Belitung University, using a two-factor completely randomized design. The first factor was KNO₃ concentration (0, 0.25%, 0.5%, 0.75%, and 1%), and the second factor was soaking duration (1, 12, and 24 hours). The research results indicate that the application of KNO₃ at various concentrations was ineffective in breaking the dormancy of local Bangka cayenne pepper seeds. Conversely, the soaking duration significantly influenced germination percentage, growth rate, vigor index, maximum germination potential, and dormancy intensity. Soaking seeds for 12 hours resulted in the greatest improvement in seed physiological quality, yielding a germination percentage of 66.93%, a growth rate of 6% per day, a vigor index of 4.53%, and a maximum growth potential of 77.20%.

Abstract

Ageratum conyzoides is a weed that can be used as a bioherbicide because it contains polyphenols, flavonoids, tannins, and terpenes. The study was conducted at the Krajan training farm, specifically in an area planted with oil palm trees in the pre-productive phase (TBM), using a randomized block design with treatments consisting of natural surfactants derived from Daun Waru (Hibiscus tiliaceus) weighing 25 g and 50 g, dissolved in 500 ml of water, and Ageratum conyzoides liquid extract at concentrations of 3%, 5%, and 7%. The results showed that the combination of 5% A. conyzoides and 50 g of Daun Waru leaves dissolved in 500 ml of water produced a significant difference and enhanced the efficacy of allelochemical/allelopathic absorption as a bioherbicide, as evidenced by the presence of toxicity symptoms and weed mortality that continued to increase up to 30 days after application (HSA). The aim of this study was to develop the best environmentally friendly post-emergence bioherbicide formulation.

Abstract

Bean (Phaseolus vulgaris L.) is one of the horticultural crops with high economic value and is widely consumed as a source of vitamins, minerals, and plant-based protein. Bean production in Riau Province has fluctuated over the years, indicating the need for efforts to improve productivity through the application of organic fertilizers. One potential alternative is banana peel liquid organic fertilizer (POC), which contains essential macronutrients and organic matter that support plant growth. This study aimed to determine the effect of banana peel liquid organic fertilizer on the growth and yield of bean plants and to identify the optimum concentration of LOF. The research was conducted in Rambah Hilir District, Rokan Hulu Regency, from March to June 2026. The experiment employed a Completely Randomized Design (CRD) with one factor consisting of four treatments: P0 (without LOF), P1 (300 mL L⁻¹ of water), P2 (350 mL L⁻¹ of water), and P3 (400 mL L⁻¹ of water), with three replications, resulting in 12 experimental units. The results showed that the banana peel liquid organic fertilizer contained 0.11% total nitrogen (N), 0.13% P₂O₅, 0.20% K₂O, 2.72% organic carbon, a C/N ratio of 24.72, and a pH of 5.57. The application of banana peel LOF significantly affected vine length and the number of pods per plant but had no significant effect on flowering time. The best treatment was P3 (400 mL L⁻¹ of water), which produced a vine length of 99.50 cm and 32.33 pods per plant.

Abstract

This study aimed to examine the effects of liquid fertilizers derived from orange, banana, and a mixture of pineapple and papaya waste on the growth and yield of water spinach. The research was conducted at the Faculty of Agriculture Experimental Garden in Trini, Trihanggo, Gamping, using a Completely Randomized Design (CRD) with three replications. The observed parameters included plant height, number of leaves, leaf length, leaf width, stem diameter, harvestable plants per m², fresh plant weight, and fresh edible weight. The results showed that fruit waste-based liquid fertilizers had no significant effects on vegetative growth, fresh plant weight, or fresh edible weight. However, the treatments significantly affected the number of harvestable plants per m². Banana, orange, and pineapple-papaya liquid fertilizers produced 92, 91, and 92 plants/m², respectively, compared with 77 plants/m² in the control treatment. These findings indicate that fruit waste-based liquid fertilizers have the potential to increase the number of harvestable water spinach plants.
