Abstract

Based on data from the Central Statistics Agency (BPS), the use of chemical fertilisers in Indonesia has increased by 50% in the last two decades, contributing to the decline of soil fertility and groundwater pollution (Rosadi, 2023). Research by the Indonesian Institute of Sciences (LIPI) found that the use of biofertilisers from agricultural waste can reduce the need for chemical fertilisers by up to 40%, while improving soil fertility in a sustainable manner. This research will focus on the development of agricultural waste-based biofertiliser formulations, with trials of their application in various crop types and land conditions in Indonesia. This research uses an experimental method with a quantitative approach, which aims to develop and test the effectiveness of agricultural waste-based biofertilisers. Table 1. The Bima variety (a1) has a larger number of plants than the Mentes variety (a2). Nutrient management also has a major impact on plant growth. Application of one dose of recommended NPK together with 100 kg/ha of pearl NPK (b3) and one dose of recommended NPK together with organic fertiliser and biofertiliser (b4) resulted in the highest plant growth at 8 weeks of age (Table 1). In the experiment, intensive pest control was carried out in the field. As a result, onion caterpillar (Spodoptera exigua hubn) populations per clump were low and fusarium wilt (Fusarium oxysporum hanz) infestation levels were generally low in both variety and nutrient management treatments. There was no evidence that varietal treatments or nutrient management had a significant impact. The application of agricultural waste-based biofertilisers not only improves crop yields, but also supports the sustainability of the agricultural ecosystem by minimising the use of synthetic chemicals and optimising the use of available resources.

Abstract

Modern agriculture faces a major challenge in maintaining high productivity while preserving the environment. In recent decades, the use of synthetic chemical fertilisers has become a common practice worldwide to increase crop yields (Sari, 2023). This research aims at analysing the effect of organic fertiliser use on plant and soil quality. This research uses a quantitative method with a field experimental approach. This approach was chosen because it allows researchers to directly measure the effect of organic fertiliser use on soil quality and plants under environmental conditions. From the results in table 3 regarding the effect of granular and bulk organic fertilisers on plant growth, it shows that the NPK treatment alone produces the highest plant height (33.6 cm) with a production of 17.7 t/ha. In Table 4 regarding the effect of fertiliser treatment on dry weight and stem varieties, the combination of NPK with NPK + 2 t POG organic fertiliser gave a dry weight of grain of 19.5 kg and a dry weight of straw of 21.5 kg. From the results shown in Table 3, it can be seen that the use of bulk (PO bulk) and granular (POG) organic fertiliser has a positive effect on plant growth compared to the control. In Table 4, the combination of NPK with 2 tonnes of straw or granulated organic fertiliser (POG) resulted in an increase in grain dry weight, especially in the NPK + 2 t POG treatment, which reached 19.5 kg dry weight. From the results of this study, it is clear that the use of organic fertilisers significantly improves soil fertility and crop yields, especially when combined with chemical fertilisers such as NPK. Organic fertilisers not only improve soil physical and biological properties, but also increase the effectiveness of chemical fertilisers.

Abstract

This research aims to evaluate the effectiveness of smart irrigation systems in increasing agricultural productivity in a specific area. The study used a group randomised design (RAK) with two main treatments: Treatment 1 (P1): Use of IoT-based smart irrigation system. The results show that smart irrigation significantly increased crop productivity (34.9% higher than traditional irrigation systems) through precision watering that matches crop needs. Water savings of up to 47.8% prove that the system is able to optimise the use of water resources, while supporting agricultural sustainability. Smart irrigation systems are proven to be more effective than conventional irrigation in improving crop productivity, water resource efficiency and economic returns.

Abstract

Internet of Things (IoT) technology has emerged as a potential solution to solve various problems in modern agriculture. This study uses a quantitative-descriptive approach with the aim of describing the application of IoT technology in agricultural management and identifying factors that influence its successful implementation. This approach is also complemented by a qualitative study to explore farmers' and experts' insights on the challenges and benefits of implementing IoS in the agricultural sector. The results show that the majority of informants have positive perceptions of the benefits of the application, especially in the form of improved water and fertiliser use efficiency, increased crop yields, and labour and time savings. The majority of farmers with a good understanding of the technology have a positive perception of its benefits, with 15 and 20 farmers rating it as very useful, respectively. However, there are major obstacles, namely the need for adequate infrastructure, training for farmers, and subsidising implementation costs. Theories of technological efficiency, technology adoption, and resource management support these findings, which suggest that successful implementation depends on infrastructure readiness as well as access and support for farmers.

Abstract

The structural transformation of Indonesia’s agrarian sector has triggered a demographic crisis marked by a significant decline in youth participation in agriculture. This study examines the relationship between stagnant farmer regeneration and rising mechanization intensity, focusing on how youth labor scarcity drives agricultural technology adoption. Using an econometric framework, the analysis integrates secondary data from the 2023 Agricultural Census and the 2020 Population Census Long Form. Regression models are applied to data from 514 regencies to assess the impact of demographic imbalance on mechanization uptake. The results reveal a strong positive association between labor scarcity and mechanization (p < .001), particularly in major production regions dominated by elderly farmers. Empirical estimates indicate that a 10% reduction in youth labor participation increases mechanized service utilization by 4.12%, confirming machinery as a functional substitute for human labor in aging rural economies. The study concludes that although demographic pressure accelerates technological adoption, its effectiveness depends on managerial capacity and targeted government support. These findings provide policy-relevant insights for achieving food sovereignty through demographically adaptive agricultural transformation.
