Abstract

TSS (True Shallot Seed) merupakan benih botani alternatif selain umbi yang sangat potensial untuk digunakan dalam proses budidaya bawang merah. Proses pembibitan di petani umumnya menggunakan metode tebar langsung pada lahan dengan tingkat persentase tumbuh yang rendah. Hal tersebut menjadi permasalahan dalam penerapan TSS di lapangan. Penelitian ini bertujuan untuk melakukan studi pembibitan benih TSS menggunakan metode hidroponik, khususnya sistem aeroponik dengan modul ultrasonic atomizer sebagai pengabutan larutan nutrisi. Percobaan menggunakan 3 jenis varietas TSS yaitu Lokananta, Tuktuk dan Sanren. Proses penyemaian bibit dilakukan selama 7 minggu pada ruangan dengan kisaran suhu 23,5-29 oC serta kelembapan relatif sebesar 54,1-75,7 %. Penyinaran fotosintesis menggunakan cahaya LED White dengan nilai photosynthetic photon flux density (PPFD) rata-rata sebesar144 mmol/m2/s. Diperolah hasil performa performa pengabutan ultrasonic atomizer sebesar 89,71 % pada konsentrasi larutan nutrisi 135-1.048 ppm. Sistem aeropnik mampu menghasilkan bibit bawang merah TSS dengan performa keberhasilan pembibitan rata-rata sebesar 89,29 %. Varietas Lokananta, Tuktuk dan Sanren secara berurutan memiliki tinggi tanaman rata-rata sebesar 32 ± 3,61 cm, 34,47 ± 4,52 cm dan 30,2 ± 3,53 cm dengan jumlah daun rata-rata sebanyak 4,07 helai, 4,33 helai dan 4,01 helai. Keragaan tanaman tersebut sesuai dengan kriteria bibit TSS bawang merah. Penggunaan TSS dapat menjadi alternatif penyediaan bibit berkualitas untuk petani bawang merah di Indonesia.

Abstract

The fertigation control system has been extensively developed, particularly for hydroponic plant cultivation. However, existing studies often overlook the characteristics of the interaction between the environment and plants. Evapotranspiration and the moisture status of the growing medium are two critical parameters in determining the volume of fertigation. As a control system, fuzzy logic can manage fertigation based on these two parameters. This study aims to deliver water and nutrients to plants more effectively and efficiently, aligning with current environmental conditions and plant needs. The research was conducted through several stages: defining design criteria, creating a fuzzy logic design, simulating the fuzzy logic-based fertigation control system, and testing the system. Simulation results indicate that when the moisture content of the growing medium is between 26% and 31%, the fertigation duration varies according to evapotranspiration values. When the moisture content exceeds 32%, fertigation does not occur regardless of evapotranspiration values. Testing results demonstrate that the fuzzy logic used in this control system is efficient in delivering fertigation, as evidenced by minimal runoff compared to systems without control. Additionally, the moisture status of the growing medium consistently remains within the available water zone or at the optimum condition for plant water absorption, with a mean absolute percentage error of 1.98%. The designed fuzzy logic control system is also effective in providing fertigation, with the total volume ranging from 132 to 308.4 ml/day, closely matching the daily evapotranspiration rate. Based on plant physiological measurements, the fuzzy logic control system outperforms fertigation without control.

Abstract

Melons are become a popular fruit cultivating inside the greenhouse using the drip irrigations in Indonesia. The application of internet of things-based monitoring is beneficial to optimize cultivation management. Another issue on melon cultivation inside the greenhouse is automation of the water and nutrient delivery. However, currently monitoring and control is expensive and difficult to modify by farmers. The aim of this study was to develop a low-cost technology and easy to use by farmers using internet of technology. The method used in this study consisted of analysis, design and implementation. The result of this study was a system monitoring to monitor air temperature, air humidity, media humidity and solar radiation inside the greenhouse integrated with nutrient or water delivery using drip irrigation. A web-based dashboard was developed as a user interface for the farmers and users. The overall cost to develop a system monitoring and control was 358.24 USD not including the water thank and nutrient delivery system (pump and irrigations pipe). The system was deployed and tested at Agribusiness and technology park IPB University.
