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

The Indonesian agricultural sector faces significant challenges in entering the era of digitalization and the Industrial Revolution 4.0. This study aims to examine the strategy for developing human resource (HR) competencies in the agricultural sector to face digital transformation through a comprehensive literature study. The results of the study indicate that the digital and competency gaps are still the main obstacles to sustainable agricultural development. The strategy for developing agricultural HR must include: (1) updating the agricultural education curriculum based on digital technology; (2) strengthening training programs and technology assistance for farmers; (3) developing penta-helix partnerships between stakeholders; (4) creating inclusive digital ecosystem in rural areas; and (5) implementing integrated agricultural HR empowerment policies. Implementation of these strategies requires ongoing commitment from the government, educational institutions, the private sector, and farmer communities to create adaptive and competitive agricultural HR in the digital era.

Abstract

This study aims to determine the role of agricultural extension workers and the priority of agricultural extension workers' activities in empowering farmers in the city of Yogyakarta. The method used is a combination of quantitative and qualitative approaches to produce more comprehensive, valid, reliable, and objective data. Each farmer group is made up of 5-7 farmers so that the total sample is 88 farmers. Data sources consist of primary and secondary data collected through observation, literature study, interviews, questionnaires, and documentation. Data analysis uses the Customer Satisfaction Index (CSI) and Importance Performance Analysis (IPA) methods. Based on the results of this study, it shows that the success of extension workers in social and technical roles has been felt by farmers, but the dimensions of responsiveness and anticipation are critical aspects that still need to be strengthened in order to answer the dynamics of urban agriculture in Yogyakarta.

Abstract

Water is an important component in shallot cultivation activities, optimal water availability is very necessary in shallot cultivation activities, especially in the early stages of growth and bulb formation. Traditional irrigation methods tend to be wasteful and unpublished in air distribution which can result in decreased yields, especially in cultivation activities carried out in areas with limited air. Sprinkler irrigation appears as a potential solution to optimize air distribution through a spraying mechanism that allows for more even air distribution. The research design used was a one-factorial Completely Randomized Design with five replications. Irrigation carried out in this study was in the form of traditional control 100% manual irrigation needs (I0), sprinkler 75% manual irrigation volume (I1), sprinkler 100% manual irrigation volume (I2), sprinkler 150% manual irrigation volume (I3) and sprinkler 200% manual irrigation volume (I4) which were given once in the morning at 06.00 -07.00. This study aims to analyze the effect of the use of a sprinkler irrigation system on shallot productivity. The results showed that sprinkler irrigation with a volume of 200% of the manual method gave the best results on plant height, number of tillers, dry weight of the stump, and diameter of the shallot bulb. In contrast, the traditional irrigation method with 100% manual volume produced the lowest bulb weight loss. Sprinkler application with 200% manual irrigation volume can significantly increase shallot production.

Abstract

Sorghum (Sorghum bicolor L) is one type of cereal plant that is a local and national food because it is resistant to disease and can be cultivated on marginal land. The local variety Watar Hammu Miting Tadda comes from East Sumba and has the potential to be developed in the highlands such as Kopeng, Central Java, which has different climate and soil characteristics. This study aims to determine the response of local sorghum Watar Hammu Miting Tadda to nitrogen (N) fertilizer. The study used an experimental method with a Randomized Block Design (RAK), five N fertilizer dose treatments (control; 2.44; 3.69; 4.89; and 6.08 g/plant), and four groups. The parameters observed included plant height, number of leaves, stem diameter, dry stalk weight, panicle length, seed weight per plant, tiled seed weight, and 100 seed weight. The results of the analysis showed that the N fertilizer dose treatment had a very significant effect on plant height at the age of 6 MST, with the highest height obtained at a dose of 6.08 g/plant (104.49 cm). However, the treatment did not significantly affect other parameters, such as seed weight and panicle length. The highest seed weight was recorded at a dose of 3.69 g/plant (302.38 g). This indicates that plant vegetative growth is more responsive to N fertilizer than harvest yields. These results also demonstrate the importance of site-specific nutrient management and the use of adaptive varieties to optimize yields.

Abstract

This study aims to analyze the efficiency of red chili agribusiness supply chain structures in Sindulang Village, Cimanggung Subdistrict, Sumedang Regency. Efficiency is measured by indicators such as distribution chain length, production cost (HPP), marketing margin, farmer’s share, and cash flow cycle. The research applied a qualitative case study approach using descriptive and diagnostic analysis. Results reveal three main supply chain structures: independent farmers, cooperative-partnered farmers, and company-partnered farmers. The independent farmer model was the most efficient, having the shortest chain, lowest HPP, smallest marketing margin, and highest farmer’s share (50%). The cooperative model was the least efficient, with the lowest farmer’s share (38%), highest HPP, and the longest cash cycle. The company-partnered model ranked moderate in efficiency. These findings emphasize that supply chain efficiency is significantly influenced by institutional structure, distribution system, and the integration of information among actors.

Abstract

This study aims to analyze the impact of crop rotation on the economic perspective of horticulture farmers in Landono District, South Konawe Regency, using a qualitative approach. In horticulture farming, cost efficiency and income optimization are key to success. Although quantitative data from three farmers (Nanang, Yohan, and Suparti) show differences in financial performance, a deep understanding of how farmers perceive and manage crop rotation practices and their impact on their economic condition still needs to be explored. Through in-depth interviews, this study explores farmers' understanding of crop rotation concepts, the practices they undertake, and their perceptions of its influence on farming costs, income, and profits. Initial findings suggest that farmers who intensively apply crop rotation tend to have a more positive view of their farming efficiency, although this is not always directly proportional to the highest absolute profit. This study concludes that farmers' understanding of crop rotation as an economic efficiency strategy needs to be strengthened through appropriate counseling and policy support.

Abstract

Red chili is widely used as a key ingredient in various traditional dishes. However, its availability often fluctuates due to seasonal changes, pest and disease outbreaks, and distribution challenges, resulting in unstable market prices. This study aims to evaluate the effects of different concentrations of rice washing wastewater and varying dosages of NPK fertilizer on red chili plants (Capsicum annuum L.). It also investigates whether there is a significant interaction between these two treatments on the plant's growth and yield. The research employed a factorial Completely Randomized Design (CRD) with two treatment factors and one control. The first factor was the concentration of rice washing wastewater at three levels: 150 ml/plant, 300 ml/plant, and 450 ml/plant. The second factor was the dosage of NPK fertilizer: 10 g/plant, 15 g/plant, and 20 g/plant. The results indicated a significant interaction between the wastewater and fertilizer treatments on stem diameter at 4 weeks after transplanting and fruit diameter. The best outcome was observed with the application of 450 ml/plant of fermented rice washing water, which significantly improved plant height at 4 weeks, number of fruits, and fruit weight.

Abstract

Leaves are essential organs in plant physiology as they store unique morphometric information for each variety. The leaf constant is an important parameter because it can be used to efficiently estimate leaf area. This study aimed to identify the leaf constant values of avocado variety Hass and mangosteen variety Kaligesing using digital image processing methods. The research was conducted at the Agrotechnology Laboratory, University of Pekalongan. Leaf images were calibrated and processed using ImageJ software to obtain leaf area values. The leaf constant was found to be 0.722 for avocado and 0.661 for mangosteen. These constants were then used to predict leaf area, which was validated against measured leaf area from digital image processing using statistical analysis. The results showed determination coefficients (R²) of 0,9984 for avocado and 0,9915 for mangosteen, with RMSE, NRMSE, NSE, and d values indicating a very high level of agreement. This study demonstrates that leaf constants obtained through digital image processing can be used to model leaf area accurately, quickly, and non-destructively.
