Land conversions pose a threat to food security. Urban agriculture is considered to be a solution to this issue. Urban agricultural innovations are diverse, including vertiminaponics, cube-model microirrigation, and Nonpowered Automatic Fertigation systems. The development of a powerless automatic fertigation innovation involves creating a portable Minapadi concept by substituting some components, such as pots, with fiberglass boxes. This study aims to achieve a good box design to support the concept of urban agriculture. The study began by testing 10 fiberglass samples on a UTM machine to obtain the mechanical properties of the material, such as the modulus of elasticity, which were input into a computer simulator along with other physical and mechanical properties. The computer-aided simulator used was the ANSYS 2024 R2 Student software, simulating two potential box designs: the first box had a thickness of 4 mm with a lateral support in the middle of its vertical span, while the second box had a thickness of 6 mm without lateral support. Loading was applied hydrostatically with water level heights ranging from 50 to 400 mm and thermal loading simulating solar radiation. The results of this study show that solar radiation has a minimal impact on box deformation, whereas water-level height plays a significant role in box deformation. The first box design was considered the best based on deformation due to hydrostatic pressure, with a maximum deformation of 2.175 mm under hydrostatic loading with a water level height of 400 mm.

High temperature is the major constraint to potato cultivation in the lowland for it causes stress and inhibit initiation of potato tuber. This study was designed to investigate the effects of root zone cooling upon seed potato production using aeroponics system in lowland wet tropical climates. Cultivation techniques used in this study was the aeroponics system with three cooling temperatures (10, 15, and 20 oC) and control (greenhouse room temperature). Plantlet of potato ‘Granola’ variety derived from tissue culture propagation were used. The results showed that the highest number of tuber and tuber weight that can be harvested up to 90 days after planting were obtained from cooling the root zone temperature at 10 °C with the average number of tuber 14.85 tubers plant-1and average weight of tubers 409.15 mg tuber-1. Plants grown at root zone cooling at 15 and 20 °C treatments produced lower number of tubers and lower tuber weight than at 10 oC, while plants grown at greenhouse temperature did not produce tubers.Keywords: cultivation techniques, Granola, high temperature, lowland tropical, potato tuber

ABSTRACTNutrition pumps pressure is important in aeroponic. Optimal pump pressure produces well oxygenation, so that increases the dissolved oxygen content in the nutrition. It is good for plant roots. The purpose of this study was to determine pump pressure on the growth and yield potato seeds grown in aeroponics in lowland 125 m asl with root zone cooling. This study used a randomized block design non factorial. Data were analyzed using analysis of variance followed by a further test of orthogonal contrasts at the level of α = 5%. Results showed that different pump pressure on the provision of nutrient, temperature cooling in the root zone gave different results on the number of potato tubers per plant and weight per tuber in each variety. Root zone cooling temperature 15 °C, the pump pressure> 1.5 atm produce highest number of tubers per plant, i.e. 11.8 tuber of Granola variety and 8.2 tuber of Atlantic variety. The was no tuber produced from control (without referigeration). The highest weights per tuber (10.35 and 5.01 g for Atlantic and Granola variety, respectively) were reached with cooling temperature at 15 °C and the pump pressure > 1.5 atm.Keywords: evaporative cooling, hydroponics, potato, tuber, variety

The construction of the Plaza Aspirasi Building experienced significant delays due to the contractor's weak technical and managerial readiness, land issues that led to a 43-day work stoppage, and the contractor's unpreparedness to fulfill the implementation plan. This condition caused the progress deviation to continue to increase until the project entered the critical contract category. This study aims to analyze the role of the Commitment Making Officer (PPK) in handling delays. Project delays occurred due to two factors: excuseable delays such as land claims by residents and non-excuseable delays in the form of the contractor's inability to manage the work project. The results of the study indicate that the PPK has carried out its contract control function systematically through issuing warnings, temporary suspensions, evaluation meetings, implementing tiered SCM, cross-agency coordination, and providing opportunities for work completion. Overall, the impact of delays on the project is not only seen in time deviations, but also spreads to the internal costs of service providers, work quality, and the effectiveness of contract management.

The 2022 redevelopment of Situ Cipondoh represents an engineering-based waterfront intervention aimed at improving public space quality, socio-economic functions, and environmental conditions within an urban water body. This study documents and analyzes the technical implementation of adaptive construction methods in shallow-water environments, contributing to the body of knowledge on sustainable waterfront infrastructure development in densely populated urban areas. The project focused on the arrangement of key waterfront areas, construction of a flying-deck jogging track, development of a floating market for vendor relocation, and light water normalization. This paper applies a descriptive-analytical approach using construction documentation from 2022, supported by field observations, technical specifications analysis, and post-construction evaluation to assess the effectiveness of the engineering solutions implemented. The results show that the application of a flying-deck structure supported by mini piles installed from a pontoon constitutes an adaptive engineering solution suitable for aquatic environments with soft soil conditions and limited terrestrial access. Vendor relocation to the floating market improved spatial order while maintaining local economic activities and providing formal trading infrastructure compliant with hygiene and safety standards. Overall, the redevelopment enhanced public comfort, visual quality, tourism activity, and regional asset protection while demonstrating replicable engineering approaches for similar urban waterfront contexts.

The rehabilitation of irrigation networks plays a critical role in enhancing agricultural productivity and supporting national food self-sufficiency targets as mandated by Presidential Instruction No. 2 of 2025. Traditional monitoring practices still rely on manual reporting, inconsistent documentation, and non–real-time inspections, leading to data inaccuracies and limited transparency. These challenges highlight the need for a more reliable, timely, and objective monitoring system. SIMORI (Irrigation Monitoring Information System) is introduced as an AI-powered digital solution capable of providing real-time data, detecting anomalies, and generating accountable automated reports. This paper explores the relevance and urgency of SIMORI as a strategic instrument to enhance transparency, accountability, and monitoring quality in irrigation rehabilitation projects, thereby accelerating national food security objectives.

Produksi kayu dari hutan tanaman industri di Indonesia meningkat dari 18,8 menjadi 49,6 juta m³ pada periode 2015–2022. Peningkatan ini menuntut ketersediaan bibit dalam jumlah dan kualitas yang memadai. Umumnya, pembibitan dilakukan menggunakan biji atau stek di dalam greenhouse, kemudian dipindahkan ke luar ruangan saat mendekati waktu tanam. Keberhasilan pembibitan di dalam greenhouse sering terkendala oleh suhu yang melebihi batas toleransi tanaman, sehingga menghambat pertumbuhan. Penelitian ini bertujuan mengidentifikasi fluktuasi suhu di dalam greenhouse pembibitan Eucalyptus sebagai sumber bahan baku industri pulp dan kertas, serta mengembangkan model pindah panas yang sesuai dengan kondisi greenhouse tersebut. Kondisi iklim di dalam dan di luar greenhouse diukur menggunakan automatic weather station dengan interval 30 menit selama lima bulan. Model pindah panas yang dikembangkan menjelaskan pengaruh perubahan iklim luar terhadap suhu di dalam greenhouse. Berdasarkan kondisi greenhouse, perbedaan suhu antara lantai dan atap diabaikan sehingga model menjadi lebih sederhana. Model menghasilkan koefisien determinasi (R²) sebesar 0,9051 dan root mean square error (RMSE) 1,31°C. Fluktuasi suhu di dalam greenhouse relatif lebih stabil, dengan rata-rata suhu 0,1°C lebih rendah dan kelembapan relatif 2,9% lebih tinggi dibandingkan di luar. Keterbatasan model ini adalah ketidakmampuannya memprediksi suhu ekstrem di luar secara akurat. Oleh karena itu, diperlukan pengembangan lebih lanjut, termasuk mempertimbangkan kemungkinan perubahan nilai parameter pindah panas pada kondisi suhu yang lebih ekstrem.
