Abstract

Marginal alluvial soils are characterized by low fertility, acidic pH, and limited nutrient availability, which constrain agricultural productivity. This study investigated the effects of goat manure and liquid organic fertilizer (POC) from tofu wastewater on okra growth and yield in alluvial soil. A completely randomized factorial design was employed with two factors: goat manure doses (50, 100, 150 g/polybag) and tofu wastewater POC concentrations (10%, 20%, 30%), each replicated three times, resulting in 27 experimental units. Soil analysis revealed significant improvements in chemical and physical properties after treatment application. Initial soil pH increased from 4.82 to 5.9, organic carbon content rose from 1.82% to 3.05%, total nitrogen increased from 0.16% to 0.42%, and available phosphorus improved from 18.3 ppm to 92.14 ppm. Physical properties also enhanced with bulk density decreasing from 1.62 to 1.24 g/cm³ and total porosity increasing from 34.21% to 46.37%. ANOVA analysis showed significant effects of POC concentration on plant height and fruit weight, with 20% concentration producing optimal results. Goat manure significantly influenced fruit weight, with the highest dose (150 g/polybag) yielding 89.44 g compared to 56.96 g at the lowest dose. No significant interactions were observed between the two factors. The results demonstrate that combined application of goat manure and tofu wastewater POC effectively transforms degraded alluvial soil into fertile growing medium, supporting sustainable okra production in marginal lands.

Abstract

Mina padi is a rice-fish farming an agricultural innovation that integrates rice and fish cultivation on a single plot of land with the aim of increasing land productivity and water resource efficiency. Mina padi is a form of agricultural innovation that prioritizes environmental sustainability in water management, minimizes the use of chemical pesticides and fertilizers, reduces pests, and provides double benefits for farmers. This study aims to determine: the sustainability of mina padi from economic, social, and environmental aspects; analyze internal and external factors in mina padi; and design sustainability strategies for mina padi. The method used in this study is descriptive qualitative to describe the research results in greater depth. There are 13 informants in this study. The results of the study indicate that mina padi provides significant economic benefits, with an R/C Ratio of 1.24, meaning that every Rp 1 spent generates Rp 1.24 in revenue, making it worthwhile to pursue. Strategies that can be implemented for the sustainability of mina padi include: 1) increasing farmers' motivation to improve mina padi production through land intensification, such as the use of liquid organic fertilizer, adding natural feed, using high-quality seeds, and proper land preparation; 2) establishing partnerships with local restaurants and markets for sustainable absorption of harvests, 3) developing agrotourism with the support

Abstract

Determining growth centers for local governments is very important, in order to make it easier to accelerate regional development. The more developed the growth center, the more developed the hinterland or supporting areas will be. The purpose of this research is to find out which sub-districts are the centers of economic growth, how much interaction occurs between sub-districts that act as growth centers with surrounding areas / sub-districts, the position of the economy in each economic sector and to find out the leading sectors in Hulu Sungai Tengah Regency. There are 11 sub-districts in Hulu Sungai Tengah Regency. This research is a type of quantitative descriptive research and uses secondary data sourced from books published by BPS Hulu Sungai Tengah Regency. This research uses Scalogram Analysis, Interaction/Gravity Analysis, Klassen Typology and LQ (Location Quotient). The results showed that in 2020 there were four sub-districts that had hierarchy I and hierarchy II so that they became growth center sub-districts, these sub-districts were Barabai, Haruyan, Pandawan and Batang Alai Selatan. The level of interaction between the growth center sub-districts and their surrounding sub-districts varies. Based on Klassen's typology analysis, the agriculture, forestry and fisheries sector is in Quadrant 1, which indicates that it is a developed and rapidly growing sector. The results of the LQ (Location Quotient) analysis show that the agriculture, forestry and fisheries sector (LQ = 1.83) is one of the leading sectors in Hulu Sungai Tengah Regency.

Abstract

This study investigates the theoretical frameworks of innovation adoption and farmer behavior within the context of Indonesian agriculture, with the aim of exploring their implications for the advancement of the agricultural sector. Theories of innovation adoption and farmer behavior provide essential lenses through which the dynamics of technological uptake and decision-making processes in agriculture can be understood. Employing a literature review methodology, this paper analyzes a wide range of sources, including peer-reviewed journals, reports, academic textbooks, and recent statistical data relevant to both theoretical models. The analysis reveals that the adoption of agricultural technological innovations is shaped by a combination of internal factors—such as farmer demographics (age, education, experience), attitudes toward risk, and perceptions of innovation—and external factors, such as access to information, financial resources, and institutional support. A thorough understanding of these elements is expected to serve as a strong basis for developing effective strategies and policies aimed at enhancing the adoption of agricultural technologies in Indonesia.

Abstract

Urea fertilizer has a relatively high nitrogen content (45%) compared to any other nitrogen-source fertilizers. However, due to urea's ability to dissolve readily, nitrogen fertilizer in the form of urea often has a poor efficacy. The environment will lose around 70% of the urea fertilizer during the process, including soil ammonia evaporation and urea degradation. One of the methods to increase fertilization effectiveness is to coat it with slow-release fertilizer technology. The specific objective of this study is to determine the characteristics of urea slow release fertilizer with an encapsulation technique by using natural zeolite biocomposites-alginate and nitrogen release patterns as slow release fertilizer candidates. The characteristics of biocomposites were evaluated using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and spectrophotometer analysis for nitrogen release tests. This experiment used natural zeolite biocomposite-alginate to encapsulate the urea as an environmentally friendly slow-release fertilizer. The FTIR spectroscopy showed the presence of natural zeolite-alginate biocomposite. The SEM images showed the surface morphology of urea which had been coated by a natural zeolite-alginate biocomposite. The percentage of urea released for 72 hours at zeolite-alginate ratio of 1:1, 2:1, 3:1 were 16.10%, 21.03%, and 17.51%, respectively. This result shows that urea encapsulated by biocomposite with 1:1 ratio has the least percentage of urea release compared to the others. The biocomposite with 1:1 ratio exhibited the best performance in resisting nitrogen release from urea fertilizer. This study indicates that natural zeolite-alginate biocomposite is an alternative candidate for developing the efficiency of slow-release urea fertilizer.

Abstract

Shallot (Allium ascalonicum L.) is an important horticultural crop in Indonesia, yet its productivity remains relatively low, especially in suboptimal lands such as alluvial soils. This study aimed to evaluate the effects of combining chicken manure and NPK Mutiara fertilizer on the growth and yield of shallots in alluvial soils of West Kalimantan. The research was conducted from January to March 2025 at the Experimental Garden of the Faculty of Agriculture, Panca Bhakti University, Pontianak, using a factorial Completely Randomized Design (CRD) with two factors: chicken manure (40, 80, and 120 g/polybag) and NPK Mutiara fertilizer (6.22, 7.95, and 9.26 g/polybag). Observed parameters included plant height, number of leaves, number of bulbs, and fresh bulb weight. The results showed that the combination of treatments had no significant effect on all growth and yield parameters. However, the combination of a3n3 (120 g chicken manure and 9.26 g NPK Mutiara) produced the highest average plant height (33.11 cm), while the a2n3 combination resulted in the highest fresh bulb weight (116.67 g). The absence of significant effects is presumed to be due to insufficient nutrient supply under acidic and organic-poor alluvial soil conditions. Further research is needed to determine the optimal dosage and fertilization combination to improve shallot yields on suboptimal land. Recommended to adjust the dosage of chicken manure and NPK Mutiara fertilizer for optimal results, use high-quality seeds with a greater number of active buds, and improve the organic matter content of alluvial soil prior to planting.
