Abstract

This study examines the energy efficiency and financial feasibility of cherry tomato cultivation in a Venlo greenhouse in West Java, Indonesia. The agricultural company operating this greenhouse faces challenges arising from improper design and technology selection, including elevated internal temperatures unsuitable for optimal plant growth. A fan-pad cooling system mitigates this issue but results in high energy consumption, with electricity accounting for 90.26 % of total energy use. The input–output energy ratio (5 %) and energy productivity (0.06 kg/MJ) indicate significant inefficiencies in resource utilization. Financial analyses reveal negative Net Present Value (NPV) and a Benefit-Cost (B/C) ratio below 1, reflecting a lack of profitability. The Payback Period (PBP) of 8.7 years highlights long-term financial risks. The findings emphasize the need for investment optimization and strategic cost management to ensure the sustainability of greenhouse-based cherry tomato production in tropical climates.

印尼西爪哇岛Pangalengan PT X温室生产樱桃番茄的投入产出能源分析及财务可行性

本研究考察了在印度尼西亚西爪哇的Venlo温室种植樱桃番茄的能源效率和财务可行性。经营这个温室的农业公司面临着设计和技术选择不当带来的挑战，包括内部温度升高，不适合植物的最佳生长。风扇垫冷却系统缓解了这一问题，但导致高能耗，电力占总能耗的90.26%。能源投入产出比（5%）和能源生产率（0.06 kg/MJ）表明资源利用效率明显低下。财务分析显示净现值（NPV）为负，收益-成本（B/C）比率低于1，反映出缺乏盈利能力。8.7年的投资回收期（PBP）凸显了长期的财务风险。研究结果强调了投资优化和战略成本管理的必要性，以确保热带气候下温室樱桃番茄生产的可持续性。
