Abstract

This study evaluates the effectiveness of soil pH enhancement and pesticide-use efficiency on operational costs and the profitability of a sustainable farming system in Gunungsari Village. In this area, rice and maize are cultivated alternately in the first and second planting seasons, heavily reliant on rainfall and irrigation. During the dry season, this dependency shifts to chemical fertilizers and water pumps, leading to a surge in operational expenses. Employing a triple bottom line approach (people, planet, profit), the methodology combines quantitative analysis via SmartPLS to identify dominant sustainability factors with system dynamics simulations in STELLA to test various policy scenarios. SmartPLS results identify soil pH as the most influential factor (44% contribution). Raising soil pH from 5.97 to 6.80 through liming and organic amendments significantly reduces reliance on urea fertilizer, lowering operational costs by 5.36–7.04% and boosting profits by 12.91% (Rice Season 1), 10.27% (Rice Season 2), 14.65% (Maize Season 1), and 13.83% (Maize Season 2). Moreover, a 20–80% increase in pesticide-use efficiency curtails production costs without sacrificing yield, supporting eco-friendly agriculture. This model provides a systemic overview of social, environmental, and economic interactions and informs data-driven policy recommendations for more efficient, adaptive, and sustainable farming.

Abstract

  Tempeh, a soybean-based product fermented by the fungus Rhizopus oligosporus, is a traditional Indonesian food known for its high nutritional value, particularly as a source of plant-based protein. The Tempeh Production House "Mas Alfin" employs both Make-To-Order (MTO) and Make-To-Stock (MTS) production systems to meet customer demands, including partnerships with catering companies. However, the tempeh production process at this facility faces efficiency challenges, particularly in the manual packaging stage, which is time-consuming and causes ergonomic complaints among workers. This study aims to develop a semi-automatic and ergonomic packaging tool to enhance production efficiency, reduce worker complaints, and improve product competitiveness. Based on anthropometric measurements, the packaging tool is designed with the following specifications: tool height of 150 cm, hand reach for input of 68.5 cm, and output height of 61.5 cm. The tool can reduce packaging time from 75 seconds to 36 seconds per kilogram, increase production capacity by up to 108%, and lower the production cost from IDR 7,058 to IDR 6,083 per 500 grams. The investment in this packaging tool achieves a payback period of 8 days, with a daily cost of IDR 383,400. Keywords: Anthropometry, Design, Tempeh

Abstract

Abstract: One of the important challenges the industry faces is the problem of raw material inventory, so good inventory management is essential. This management results in the emergence of inventory costs comparable to the company's operational costs. Inventory deviations in an industry can be in the form of less or more inventory caused by inaccurate inventory calculations, such as those experienced by PT SLU. The condition of PT SLU shows that the products produced have decreased while raw materials have an excess inventory of more than 15,000 kg. This study aims to determine the quantity of flour raw materials to achieve optimal inventory costs at PT SLU. The method used is the Markov chain and enumeration method to determine the optimal amount of raw materials to reduce costs. The research findings indicate that policy 58 yields the lowest expected cost of Rp. 32,463,360 compared to other policies. Therefore, it is suggested that improvements be implemented, such as if the system is in states 3, 4, 5, or 6, for long-term policy. This condition can help companies create strategies to reduce overstock, particularly of raw flour materials.

Abstract

This study investigates agricultural sustainability and food security in Bungur Village, Nganjuk Regency, East Java, by addressing critical challenges such as an aging farming population, heavy reliance on chemical fertilizers, and recurring pest infestations. To identify key determinants, Structural Equation Modelling–Partial Least Squares (SEM–PLS) was employed, while system dynamics modeling using STELLA software was applied to simulate three alternative intervention scenarios. The simulation results demonstrate that the adoption of semi-organic fertilizers increases profit by approximately 1% (Rp106.4 million), the use of environmentally friendly pest management enhances profit by 12% (Rp117.8 million), and the combined application of both strategies yields the highest improvement, with a 16% increase (Rp122.3 million) compared to the baseline condition (Rp105.6 million per hectare annually). Model reliability was confirmed through validation tests using mean comparison error (≤5%) and variance explained (≤30%). These findings highlight that integrated interventions are effective in improving productivity, profitability, and sustainability, while also providing incentives to encourage greater youth participation in agriculture. Nonetheless, the scope of this study is limited to Bungur Village and focuses exclusively on rice, shallots, and corn, without accounting for farmer-level heterogeneity. Future studies are recommended to extend the model to wider geographical contexts and incorporate factors such as climate variability and market fluctuations.

Abstract

Sustainable agricultural systems require efficient input management to achieve optimal results in both productivity and profitability. This study aims to develop a system dynamics model to explore strategies for increasing productivity and cost efficiency in sustainable agriculture. The research was conducted in Singkalan Village, Balongbendo District, Sidoarjo Regency using STELLA software to build a simulation model. This model captures the relationship between key variables, including the use of superior crop varieties and semi-organic fertilizer, rice and corn yields, operational costs, and farmer profits. Three management scenarios were tested: (1) increasing productivity through superior varieties, (2) reducing operational costs by applying semi-organic fertilizer by 25%, and (3) combining the two approaches. The simulation results show that the combination of scenarios provides the best results, with an increase in rice productivity of 3.96%, a reduction in operational costs of 16.29%, and a profit for rice farmers of 1.27%. These results highlight the effectiveness of the system dynamics approach in assessing input-based policy interventions and supporting sustainable profit-oriented decision making in agriculture. Keywords: cost efficiency, productivity, profitability, system dynamics
